Preface

1.1 Executive Overview

Indonesia’s ethanol sector sits at the nexus of energy security, agro-industrial upgrading, and climate strategy. While biodiesel (B30) has been the poster child of Indonesia’s biofuel push, ethanol has remained under-scaled, used mostly for industrial applications rather than transport fuel. In 2020–2025, rising energy import bills, net-zero commitments, sugarcane revitalization, and government discussion of E5–E10 blending revived ethanol’s strategic importance. Whether ethanol becomes a second national biofuel pillar depends on policy clarity, feedstock security, cost competitiveness, and infrastructure readiness.

1.2 Scope and Objectives

This report covers Indonesia’s ethanol industry (fuel-grade & industrial-grade) with time series 2020– 2025: production, consumption, prices, trade, players, capacity, policy, benchmarks, risks, and outlook.

1.3 Definitions, Grades & Use Cases

Ethanol (C₂H₅OH) is produced via fermentation and distillation. In market practice:

• Fuel-grade ethanol
  • Purity typically ≥99.5% (anhydrous), denatured for tax/regulatory purposes.
  • Use: blending with gasoline (E5, E10, E20, E85), octane enhancement, oxygenate to reduce CO and HC emissions.
• Industrial-grade ethanol
  • Hydrous (~95%) or anhydrous, denatured/undenatured per application.
  • Use: solvents, pharmaceuticals, cosmetics, beverages, food processing, inks, sanitizers, and chemical intermediates (e.g., ethyl acetate).
• Feedstocks
  • First generation (1G): sugarcane juice, molasses, cassava, corn.
  • Second generation (2G): lignocellulosic biomass residues (bagasse, rice straw, empty fruit bunches, wood wastes).
  • Third generation (3G): algal routes (R&D stage globally).
• Key by-products / co-products:
  • DDGS (grain   routes),   vinasse (as    fertilizer), CO₂  capture electricity/heat from bagasse/biomass cogeneration.

1.4 Indonesia’s Feedstock Reality (Why it Matters)

• Sugarcane & Molasses: Primary domestic 1G route. Sugar productivity and milling efficiency drive molasses availability and cost. Competes with food, export, and industrial users.
• Cassava: Technically viable but faces smallholder fragmentation, food vs fuel sensitivity, and logistics.
• Corn: Limited for fuel ethanol at scale; priority is food/feed.
• 2G biomass (bagasse,        straw,  wood   residues): Large theoretical   potential; needs capex, enzymes/pretreatment, and strong offtake economics.

1.5 Where Ethanol Fits in Indonesia’s Energy & Industry Strategy

• Energy security: Substitute imported gasoline components; diversify octane/oxygenate supply.
• Agro-industrial upgrading: Monetize molasses and residues; stabilize farm incomes; create rural jobs.
• Industrial base: Expand solvents/chemicals; enable biorefinery clusters (ethanol–ethyl acetate–CO₂– fertilizer).
• Climate policy: Lower well-to-wheel emissions; complement EV policy; support NDC targets.
• Trade balance: Reduce import reliance; enable flexible export hedging when domestic demand dips.

1.6 Industry Value Chain (Indonesia Context)

Upstream

• Crops: sugarcane (estate & smallholders), cassava (smallholders).
• By-products: molasses (sugar mills), bagasse (cogeneration), field residues (2G feedstock).

Midstream

• Fermentation & distillation: hydrous/anhydrous ethanol, dehydration (molecular sieves), denaturing.
• Utility integration: boiler/cogen (bagasse/biomass), wastewater (vinasse treatment).
• QA/QC: moisture control, denaturant specs, impurity management.

Downstream

• Fuel supply chain: terminal tanks, in-line blending/skid blending, pipeline/truck logistics, depot QA, retail dispenser compatibility.
• Industrial supply chain: drums/ISO tanks, solvent distributors, pharma/cosmetics/chemical plants.

Enablers

• Policy (excise, blending mandates), licenses, commodity balance, SNI/specs, sustainability certification (e.g., ISCC), financing & guarantees.

Market Trend and Size

2.1 Overview of the Ethanol Market in Indonesia

Between 2020 and 2025, Indonesia’s ethanol industry evolved from a stable yet overlooked industrial segment into a strategically recognized component of national energy diversification. Annual production averaged 205– 220 million liters (ML) — only a fraction of global ethanol output — but the period marked a critical policy inflection. For the first time, the government and Pertamina began integrating ethanol into the transport fuel system, moving beyond its traditional role in pharmaceuticals, cosmetics, food processing, and solvents.

Historically, Indonesian ethanol has been produced from molasses, a by-product of sugar refining. This tight linkage made ethanol output dependent on the performance of the sugar industry. Fluctuating sugarcane yields, old milling equipment, and the diversion of molasses for export caused inconsistent feedstock availability. Consequently, national distillation capacity (≈300 ML/year) operated at only 60 % utilization, leaving a large portion idle.

Policy shifts during this period began redefining ethanol’s role. Under Presidential Regulation No. 22/2017 on the General National Energy Plan (RUEN), Indonesia committed to achieving 23 % renewable energy share by 2025, with biofuels as a central pillar. While the biodiesel (B30) program advanced rapidly, ethanol lagged due to high costs, taxation, and supply issues. However, by 2023–2024 the government recognized ethanol’s potential to complement biodiesel: biodiesel substitutes diesel, ethanol substitutes gasoline.

The milestone came in August 2023, when Pertamina launched “Pertamax Green 95”, Indonesia’s first E5 gasoline (95 RON with 5 % ethanol). Produced from domestically fermented molasses supplied by PT Energi Agro Nusantara (Enero) in East Java, the product initially served Jakarta, Surabaya, and Semarang stations. Although consumption was small (~1–2 ML in 2023; 3 ML projected by 2025), the pilot proved technical feasibility: ethanol of ≥ 99.5 % purity can be blended safely in Indonesia’s logistics and retail systems.

Economically, ethanol now connects three national priorities:

1. Energy security, by reducing imported gasoline (~18 billion L in 2024, costing > USD 15 billion).
2. Agro-industrial revitalization, by absorbing molasses and stabilizing sugarcane farmer incomes; and
3. Rural employment, through new distilleries in Java, Lampung, and South Sumatra.

Every 100 ML of ethanol production sustains roughly 2,500–3,000 jobs, co-generates renewable electricity from bagasse, and enhances rural income stability. By 2025, government coordination between the Ministries of Energy, Finance, and Agriculture produced a draft policy package addressing ethanol excise reduction, blending standards, and feedstock expansion. Meanwhile, PT Perkebunan Nusantara (PTPN) Holding’s sugar revitalization plan targeted yield improvement from 65 t/ha → 90 t/ha and sucrose recovery to 9.5 %, which could raise molasses availability by 20–25 % by 2027. These agricultural reforms form the feedstock backbone for ethanol scaling. Technologically, Indonesia remains a first-generation (1G) ethanol producer but has begun R&D on second- generation (2G) routes using bagasse, rice straw, and oil-palm residues at BRIN research facilities. 2G technology, though costlier, avoids food-fuel conflicts and provides the scalability required for E10–E20 ambitions.

From an environmental standpoint, national E10 adoption would cut gasoline demand by ~3 billion L/year and reduce CO₂ emissions by roughly 1.8–2 million tons CO₂-eq annually. Thus, ethanol is no longer just a chemical; it has become a strategic bridge toward Indonesia’s Paris Agreement commitments and low-carbon transport agenda.

2.2 Market Size and Composition (2020–2025)

Total production grew only 1 % CAGR, but composition shifted as pilot fuel ethanol began entering the mix. With ~300 ML installed capacity, Indonesia has immediate room for expansion once offtake certainty improves.

2.3 Ethanol Types, Blend Standards, and Current Use

Currently ethanol is used only in RON 95 gasoline (Pertamax Green 95). Lower grades (RON 90–92) remain fossil-based E0 fuels. The staged approach mirrors Thailand’s pathway: starting with premium fuels, building consumer trust, then expanding nationwide.

2.4 Production, Feedstock, and Pricing Trends

Ethanol output closely follows sugarcane performance. A weak 2022 season triggered 96 ML of imports. Prices rose from USD 0.70/L (2020) to USD 0.93/L (2025e). On an energy basis, ethanol remains 25–30% more expensive than gasoline and faces additional excise—making blending commercially unviable without fiscal incentives.

2.5 Infrastructure and Blending Readiness

As of 2025, only five major terminals—Jakarta, Cirebon, Semarang, Surabaya, and Palembang—handle ethanol blending. These sites use truck or rack blending, since ethanol cannot share pipelines with gasoline. Nationwide E10 adoption would require USD 200–250 million in upgrades (sealed tanks, inline meters, QA labs).

Pilot operations since 2023 confirmed that E5 is technically viable with minimal modification, forming the template for regional expansion (Java–Bali first, followed by Sumatra and Kalimantan).

2.6 Market Outlook and Growth Potential

If a national E5 mandate begins by 2026, Indonesia’s ethanol demand could reach 1.5 billion L/year; E10 by 2030 would double that to ≈ 3 billion L/year. That implies a 10–15× supply increase, achievable through better cane yields, mill efficiency, and gradual investment in 2G ethanol. Policy levers—excise reform, blending incentives, and guaranteed offtake—will determine whether producers commit capital.

The 2020–2025 window thus stands as Indonesia’s learning and readiness phase. While output stayed flat, institutional capacity, inter-ministerial coordination, and pilot infrastructure matured significantly. If the government executes its 2026 E5 rollout, Indonesia could replicate its biodiesel success and transform ethanol from an industrial by-product into a national-scale renewable fuel contributing both to energy security and climate goals.

Summary of Feedstock Landscape

• Current Effective Supply (2024): ~1 million tons molasses → ≈ 300 ML ethanol equivalent.
• Total Theoretical Potential (2030): > 6 billion L ethanol equivalent if 2G feedstocks (bagasse, rice straw, EFB) are commercialized.

Key Regions:

• Java (East & Central) – legacy sugar mills, refineries, pilot E5 distribution.
• Lampung & South Sumatra – high sugarcane yield and cassava belt; export gateways.
• South Sulawesi & NTT – new frontiers for sorghum and energy crops.
• Sumatra & Kalimantan – palm residue (EFB) clusters for future cellulosic ethanol.

This profile reveals that Indonesia already possesses adequate biomass potential to support E10 scale domestically; the bottleneck lies in collection, logistics, and policy coordination rather than resource scarcity.

Major Players in the Industry

3.1 Industry Structure Overview

Indonesia’s ethanol industry remains highly concentrated and vertically linked to the sugar sector. Almost all commercial ethanol distilleries are attached to sugar mills operated by either state-owned or private plantation companies, reflecting the industry’s dependence on molasses feedstock.

The market can be divided into two major groups:

1. PMDN (Penanaman Modal Dalam Negeri) – domestic investment entities, including state-owned enterprises (SOEs) and private national firms.
2. PMA (Penanaman Modal Asing) – foreign direct investment, often joint ventures for high-purity or industrial-grade ethanol targeting export markets.

By 2025, Indonesia had approximately 10 active producers, with total installed capacity around 300–320 million liters (ML) per year but actual utilization around 60 %. The top five producers control over 80 % of output, indicating high market concentration. Most production remains industrial ethanol; only one producer (PT Energi Agro Nusantara) has achieved fuel-grade certification for blending in Pertamax Green 95.

3.2 Key PMDN (Domestic Investment) Producers

Notes:

• PT Energi Agro Nusantara (Enero) is the only producer with certified fuel-grade ethanol (≥99.5 % purity). It directly supplies Pertamina’s E5 (Pertamax Green 95) blend program.
• PT Molindo Raya Industrial (MRI) and PT Madusari Nusaperdana (MSN) are the largest industrial-grade suppliers, together accounting for over 60 % of total ethanol exports (mainly to the Philippines, Thailand, and South Korea).
• PT Medco Ethanol Lampung, originally designed for industrial-grade output, has begun feasibility studies to upgrade dehydration systems for fuel-grade ethanol by 2026.

3.3 Key PMA (Foreign Investment) Producers

 Notes:

• PMA participation remains small but strategically important, focusing on high-purity, export-oriented, or next-generation (2G)
• PT Indonesia Cellulosic Energy (ICE) is the first 2G ethanol pilot using palm residues, supported by Japanese and Indonesian research agencies (BRIN, Mitsui).
• PMA plants usually operate within export-processing zones, benefiting from VAT exemptions and simplified licensing under BKPM’s OSS framework.

3.4 Ownership and Market Concentration

The Indonesian ethanol industry is oligopolistic, with a few integrated agro-industrial groups dominating supply. The Molindo Group, Miwon (Madusari Nusaperdana), and Gunung Madu collectively contribute ≈ 75 % of total national production. PT Energi Agro Nusantara (Enero) adds a strategic state-controlled component, aligning ethanol with national fuel diversification goals. Despite this concentration, the industry’s profitability is volatile, as feedstock cost and molasses allocation vary annually with sugar yields.

Ownership trends show growing consolidation under PTPN Holding. The sugar sector restructuring program (2023–2027) aims to integrate sugar and ethanol assets into a single holding system, enabling cane-to- ethanol optimization and centralized feedstock planning, like Thailand’s Mitr Phol model. Private producers, meanwhile, rely heavily on export revenue to stabilize cash flow amid weak domestic demand.

3.5 Regional Distribution of Ethanol Production

Most ethanol plants are concentrated in Java and Lampung, reflecting the distribution of sugar mills. Future expansions (especially 2G) are expected in Sumatra and Kalimantan, leveraging palm biomass residues.

3.6 Emerging and Future Players

1. 1. PT Perkebunan Nusantara (PTPN) Bioenergy Division – exploring new cane-based distilleries in Lampung and Central Java.
   2. PT Medco Power Indonesia (Biofuels Unit) – assessing cassava-based ethanol and possible integration with biomass power.
   3. PT Pertamina Renewable Energy (under Pertamina NRE) – expected to enter the fuel-ethanol segment through blending, logistics, and co-investment with Enero.
   4. Foreign Tech Partners – Mitsui, Hitachi Zosen, and Shell Indonesia conducting feasibility for 2G ethanol using palm residues.

These new entrants could double national capacity to ~600 ML/year by 2030 if policy frameworks (E5–E10) solidify.

3.7 Challenges for Industry Players

• Feedstock volatility: dependence on molasses links ethanol output to sugar price cycles.
• Excise and taxation: ethanol is still taxed as an industrial chemical, not as renewable fuel.
• Infrastructure gap: absence of dehydration and blending facilities outside Java.
• Investment risk: unclear long-term pricing policy deters private capital in fuel ethanol.
• Export reliance: lack of stable domestic demand exposes producers to global price swings.

Despite these constraints, Indonesia’s ethanol industry has proven technically mature and export-competitive and now stands at the threshold of structural transformation once regulatory clarity emerges.

Production, Consumption, Export and Import Trends

4.1 Overview

Between 2020 and 2025, Indonesia’s ethanol industry transitioned from a stable industrial segment into a strategically observed energy commodity. Throughout this period, production volumes remained steady between 200–220 million liters (ML) annually, reflecting the limited elasticity of supply linked to molasses availability. Industrial consumption dominated (>98%) while fuel-ethanol demand only began in 2023 with Pertamina’s E5 pilot program.

However, the five-year timeline also exposed the fragility of Indonesia’s feedstock structure: in 2022, a convergence of agricultural, climatic, and policy factors caused a historic ethanol import spike to 96 ML— nearly half of domestic demand. This event, often called the “2022 ethanol shock,” underscored how dependent the industry remains on sugarcane-derived molasses and how quickly disruption in one crop year can ripple through the entire bioeconomy.

4.2 Consumption Trend (2020–2025)

Interpretation:

Industrial use remains dominant—primarily in food, pharmaceutical, cosmetic, and solvent industries—with marginal penetration into the fuel sector. The fuel-ethanol market began to register in 2023 but remained below 2% of total consumption. However, the policy trajectory clearly indicates a pending demand explosion once E5 becomes national: fuel use could reach 1.5 billion liters/year by 2026, or 10× current total production.

4.3 The 2022 Import Surge: Understanding the “Ethanol Shock”

The year 2022 stands out as the most disruptive in Indonesia’s ethanol trade history. Imports skyrocketed from 5 ML in 2021 to 96 ML, representing nearly 46% of total domestic supply. This spike was the result of compound system failures in feedstock supply, market prioritization, and climatic conditions.

1. Collapse in Molasses Availability
   • Molasses production fell from ~1.0 million tons to only ~0.7 million tons, slashing potential ethanol feedstock by roughly 150–200 ML.
   • The cause was poor sugarcane performance during the 2021–2022 La Niña cycle: excessive rainfall delayed harvesting and diluted sugar content.
   • Recovery rates at state mills dropped to 4% (vs. 9.0% target), the lowest since 2016.
   • As sugar mills underperformed, ethanol plants were left with only partial feedstock allocations.
2. High Global Sugar Prices Encouraged Molasses Diversion
   • World sugar prices climbed 30% in 2022, reaching a 10-year high.
   • Many private mills optimized crystallization for sugar output, producing less molasses.
   • Molasses prices in Java and Lampung rose from IDR 900/kg (2021) to IDR 1,350/kg (2022), making ethanol feedstock economically unviable.
   • Some mills exported molasses directly to India and Thailand rather than supplying domestic distilleries.
3. Post-Pandemic Industrial Demand Rebound
   • Industrial ethanol users (food, beverage, cosmetics, pharma) saw double-digit demand growth as the economy reopened.
   • Export contracts with ASEAN clients also resumed, tightening domestic availability.
   • Producers prioritized export commitments to preserve foreign exchange, leaving local buyers short of supply.
4. Refinery Maintenance and Downtime
   • PT Molindo Raya Industrial and PT Indo Lampung Distillery underwent major maintenance in 2022.
   • Enero’s fuel-grade facility had not yet restarted operations (revived in 2023).
   • Combined, downtime reduced effective national output by ≈30–35 ML, further widening the supply gap.
5. India’s Surplus and Indonesia’s Quick Imports
   • India’s ethanol program achieved large surpluses in 2022, and exporters offered industrial-grade ethanol at USD 0.80/L CIF, below Indonesia’s domestic price (~USD 0.90/L).
   • 70% of Indonesia’s 2022 imports came from India, 20% from the U.S., and 10% from China.
   • The combination of low freight costs, currency weakness, and feedstock scarcity made importing cheaper than restarting idle capacity.
6. Lack of Strategic Feedstock Buffer Policy
   • Indonesia had no national molasses reserve or stabilization scheme (unlike Thailand’s “Cane and Sugar Fund”).
   • Every sugarcane fluctuation immediately affected ethanol producers.
   • The absence of a feedstock balancing mechanism forced imports as the only short-term solution.
7. Outcome
   • Domestic ethanol output stagnated, industrial users scrambled for imports, and the price gap between domestic and imported ethanol narrowed to only USD 0.05/L.
   • The government issued emergency import permits through Kemenperin and BKPM to secure pharmaceutical and beverage supply continuity.
   • However, these imports were all industrial grade, not fuel ethanol.
   • The episode revealed that Indonesia’s ethanol sector remains feedstock-fragile, not technologically constrained.

4.4 Export Trend (2020–2025)

Exports act as a pressure valve for fluctuating domestic demand. Indonesia exports mostly industrial-grade ethanol (96%), while retaining minimal quantities for domestic blending. Future expansion of the E5–E10 program will likely reduce exports by 70–80%, redirecting supply to local markets.

4.5 Import Trend (2020–2025)

Interpretation:

• The 2022 anomaly was a one-off corrective shock.
• Imports quickly normalized as cane yields rebounded in 2023.
• Long-term import dependency remains negligible, but 2022 proved Indonesia lacks feedstock resilience

Potential Challenge and Structural Issues in Indonesia

5.1 Feedstock Dependency and Agricultural Volatility

Indonesia’s ethanol industry rests on a fragile single feedstock base—sugarcane molasses—which supplies roughly 88% of total input volume. Production swings in sugarcane output or sucrose recovery directly translate into ethanol supply shocks.

Between 2020–2025, the national average sugar recovery rate hovered between 7.5–8.5%, well below regional peers (Thailand 9.8–10.2%). In 2022, molasses availability dropped by nearly 30%, slashing potential ethanol feedstock by 150–200 million liters (ML) equivalent.

Key constraints:

• Ageing cane cycles and poor varietal replacement.
• Low mechanization—average cane cutting cost ≈ IDR 70,000/ton vs IDR 45,000/ton in Thailand.
• Cane allocation conflict: mills prioritize sugar crystallization when global prices rise, diverting molasses exports.

Consequences:

• Utilization rates at distilleries rarely exceed 70%.
• Volatile feedstock pricing → unstable ethanol cost base.
• Feedstock shortfall in 2022 forced 96 ML imports, the highest on record.

If feedstock diversification (cassava, sorghum, or 2G residues) is not realized, ethanol output will remain capped at 200–220 ML/y, regardless of distillation capacity growth.

5.2 Feedstock–Capacity Mismatch by Region

While Java and Lampung host 80% of national distillation capacity, emerging feedstock resources (cassava in Sulawesi, EFB and bagasse in Sumatra) remain underutilized.

This spatial imbalance—feedstock-rich, plant-poor outside Java—creates excessive logistics cost (USD 25–35 per KL transport differential) and restricts regional economic distribution. A sustainable national supply chain will depend on aligning feedstock geography with new capacity investment corridors.

5.3 Technology and Product Quality Limitations

Nearly all Indonesian distilleries operate hydrated-ethanol systems (96%) using azeotropic distillation. Only a few possess molecular-sieve dehydration units needed to produce anhydrous ethanol (≥ 99.5%) for fuel use.

Technical snapshot (2025):

• <10% of total capacity can deliver fuel-grade output.
• Conversion cost from hydrated → anhydrous ≈ USD 6–8 million per 30 ML unit.
• Energy intensity ≈ 2.2 MJ/L (vs Thailand 1.5 MJ/L, US 1.3 MJ/L).
• By-products (vinasse, CO₂) largely unvalorized.

Result: most producers remain locked in industrial ethanol, missing out on the higher-volume energy market. Limited dehydration infrastructure is the single largest technical bottleneck to scaling E5/E10 fuel programs.

Cost Structure and Pricing Volatility

Domestic ethanol pricing is driven by feedstock cost (~60%), energy (~20%), and logistics (~10–15%). From 2020–2025, production cost averaged USD 0.75–0.90 per liter, exceeding global benchmarks by 10– 20%.

The persistent gap undermines fuel blending economics and reduces international competitiveness. Without productivity gains, Indonesia’s ethanol will remain structurally high-cost relative to peers.

5.4 Infrastructure, Logistics, and Quality Control Challenges

Distribution of ethanol faces significant logistical and quality hurdles:

• Limited storage and handling facilities (ethanol-compatible tanks, pipelines, inline blending).
• Water ingress and contamination risks during trucking, raising off-spec reprocessing losses ≈ 2–3%.
• Lack of centralized QA laboratories for aldehyde and moisture testing at terminal level.
• Inconsistent denaturant practices across producers.

This weak mid-stream infrastructure inflates downstream blending cost by USD 0.03–0.05/L, enough to erase refinery margin incentives. Reliable logistics is therefore as critical as production capacity.

5.5 Financial and Investment Risks

Ethanol projects in Indonesia are considered high-risk by lenders due to:

• Absence of stable offtake contracts (fuel program not yet nationwide).
• Feedstock price volatility ± 20–30%.
• High capital cost vs uncertain demand.
• Exposure to USD–IDR currency risk for imported enzymes, equipment, and chemicals.

Banks typically assign ethanol projects a WACC > 12–14%, well above energy-sector average (8–9%). This suppresses reinvestment and modernization, keeping the industry in a low-productivity equilibrium.

5.6 Sustainability and Environmental Pressure

As global markets move toward low-carbon certification (EU RED III, ISCC, RSB), Indonesia’s ethanol producers face rising scrutiny.

Current gaps:

• No verified life cycle GHG data at national level.
• Minimal vinasse treatment → COD loads > 20,000 mg/L in effluent streams.
• Inefficient energy integration (steam reuse <40%).

These issues elevate reputational and export risks. The next growth phase will require embedding sustainability as a production KPI, not a marketing label.

5.7 Human Capital and Technical Skills

Ethanol operations demand cross-disciplinary expertise (fermentation, chemical engineering, instrumentation). Key weaknesses:

• Dependence on legacy operators; average workforce age > 45 years.
• Few specialized training centers for biofuel engineering.
• Low exposure to process digitalization and predictive maintenance.

Human-resource renewal and upskilling are essential to lift yield and reduce energy intensity.

5.8 SWOT Analysis of Indonesia’s Ethanol Industry (2025 Outlook)

 Benchmark and Common Practices

6.1 Overview: Global Ethanol Landscape (2020–2025)

From 2020 to 2025, the global ethanol market stabilized between 115–120 billion liters (BL) per year, dominated by fuel ethanol (>85%). The United States and Brazil accounted for over 70% of global output, while Asia—led by China, India, and Thailand—emerged as the fastest-growing regional cluster.

Average global ethanol production (2025):

Key trend:

While global demand is rising modestly (~3% CAGR), the strategic value of ethanol lies not in volume but in energy transition policy. Mature economies now treat ethanol as a carbon-reduction instrument, not just a commodity. Indonesia sits on the bottom edge of this curve, with the potential to pivot from industrial to energy-grade production—if it can replicate the operational discipline seen in Thailand or India.

6.2 Feedstock Strategy Benchmark

Observation:

Countries that achieved ethanol stability—Brazil, India, Thailand—diversified their feedstock base early. Indonesia’s molasses monoculture leaves the sector vulnerable to agricultural cycles and sugar-price fluctuations.

Best practice: Thailand’s “dual feedstock” model (molasses + cassava) allowed ethanol capacity utilization above 90%, regardless of seasonal cane output.

6.3 Market and Blending Practices

Benchmark Analysis:

• Brazil and the USA prove that blending mandates succeed when the distribution system and fiscal incentives are in place.
• India and Thailand show that feedstock flexibility combined with fixed-price offtake contracts creates bankable demand.
• Indonesia’s E5 pilot remains a proof-of-concept; without logistical infrastructure and uniform blending specs, expansion to E10 remains aspirational.

6.4 Second-Generation (2G) and Waste-to-Fuel Practices

Global ethanol evolution now pivots toward 2G (second-generation) production using lignocellulosic residues.

Gap:

Indonesia generates over 20 million tons of EFB and 10 million tons of bagasse annually, theoretically equivalent to 2–3 billion liters of ethanol potential. Yet, no large-scale 2G conversion exists beyond pilot stage (PT Indonesia Cellulosic Energy, Riau).

Best practices abroad:

• Brazil integrates bagasse gasification into sugar mills for cogeneration and ethanol dehydration.
• India’s 2G program provides viability-gap funding to offset enzyme and logistics cost—an approach Indonesia could adapt.
  • Key Lessons from Global Leaders

1. Brazil – Integration and Flexibility
   • Full integration of sugar and ethanol economics via flexible-crush mills.
   • Ethanol-to-sugar switching mechanism allows dynamic response to market prices.
   • E27 blending and E100 flex-fuel vehicles create a closed domestic loop.

→ Lesson for Indonesia: integrate PTPN sugar mills with ethanol refineries under a unified yield management model.

2. United States – Market Instruments
   • Ethanol supported through Renewable Fuel Standard (RFS) and tradable RIN credits, providing price certainty.
   • Corn-ethanol co-products (DDGS) generate secondary revenue.

→ Lesson: monetize by-products like CO₂, vinasse, and fertilizer to reduce ethanol’s effective cost.

3. India – Multi-Feedstock Diversification
   • Shift from molasses-only to grain + molasses within three years (2020–2023).
   • Output jumped from 8 BL to 5.0 BL, enabling E12 nationwide by 2025.

→ Lesson: multi-feedstock flexibility can more than double capacity without new distilleries.

4. Thailand – Government-Orchestrated Dual-Feedstock Stability
   • Co-development of cassava and molasses sectors stabilizes ethanol supply.
   • Central price formula aligns ethanol, cassava, and molasses economics.

→ Lesson: create regional feedstock zoning—Lampung (cassava + molasses), East Java (cane), Sumatra (2G).

5. European Union – Sustainability-Driven Incentives
   • Bioethanol industry tied to carbon reduction credit systems under RED III.
   • Encourages low-carbon, high-efficiency production rather than just volume.

→ Lesson: positioning ethanol as a carbon reduction asset could open green finance and credit trading for Indonesia.

Indonesia currently ranks last among key ethanol-producing peers in operational maturity, efficiency, and market integration—but with strong potential upside. The combination of abundant agricultural residue, rising fuel demand, and industrial base positions Indonesia to climb rapidly once systemic issues (feedstock and scale) are resolved.

6.6 Synthesis: What Indonesia Can Learn

   Government Policy

7.1 Policy Evolution and Institutional Landscape

Indonesia’s ethanol framework has evolved gradually over the past 20 years — from industrial commodity control to early renewable energy integration. However, despite several ministerial decrees and strategic plans, the sector has never achieved the policy coherence of biodiesel.

Timeline of Major Policy Milestones

Key insight:

Regulatory architecture exists, but execution gap persists because ethanol has no dedicated fiscal support, commodity balance system, or inter-ministerial execution body like biodiesel’s governance model.

7.2 Institutional Roles and Fragmentation

Ethanol policy in Indonesia spans five major ministries and two state-owned entities but lacks unified command.

This fragmented ecosystem leads to policy silos:

• Ministry of Energy and Mineral Resources (ESDM) issues blending targets but lacks funding tools.
• MoF controls fiscal levers but no biofuel-specific exemption.
• MoI manages industrial permits but cannot mandate blending.
• Pertamina and PTPN act as executors but rely on top-down instruction.

Hence, policy moves vertically, not horizontally — resulting in pilot projects rather than systemic transformation.

7.3 Existing Legal Framework Overview

1. PerMen ESDM No. 32/2008 (and Amendments)
   • Legalizes the production, distribution, and use of Biofuel (BBN) as substitute energy.
   • Defines ethanol as a qualified BBN for transportation, industry, and electricity sectors.
   • Mandates that fuel distributors (e.g. Pertamina) must procure and blend ethanol-based fuels.
   • However, the enforcement mechanism and pricing formula remain inactive for ethanol.
2. Presidential Regulation No. 22/2017 (RUEN – National Energy Plan)
   • Sets biofuel share target of 5% of total national energy mix by 2025.
   • Bioethanol included under liquid fuel diversification.
   • Assigns cross-ministerial coordination to achieve the target.
3. Law No. 30/2007 on Energy & Law No. 21/2014 on Bioenergy
   • Provide the overarching legal basis for renewable energy and biofuel utilization.
   • Encourage domestic industry and energy security through bio-based fuels.
4. Fiscal and Taxation Law (UU 39/2007 on Excise, PMK 160/2023)
   • Defines ethyl alcohol as an excisable commodity with Rp 20,000/L excise duty.
   • No distinction between industrial and renewable energy use → discourages ethanol fuel competitiveness.
5. Environmental Regulations (PP No. 22/2021, ESDM Technical Standards)
   • Require waste management for vinasse, LCA data, and emission control.
   • Key for future certification under ISCC or RED III alignment.

7.4 Major Policy Gaps

Despite a strong legal foundation, implementation lags due to four principal policy gaps:

1. No Dedicated Funding Mechanism
   • Biodiesel success was driven by BPDPKS Fund (Palm Oil Fund) providing subsidies and price stabilization.
   • Ethanol has no equivalent financing institution; pricing must compete directly with gasoline, which is still subsidized.
2. Excise Misalignment
   • Ethanol taxed at IDR 20,000/L → effectively penalized as a luxury or intoxicating substance.
   • As a result, ethanol for fuel blending costs 20–25% more than gasoline energy-equivalent.
3. Absent National Mandate & Supply Quota
   • There is no compulsory E5/E10 regulation specifying blending ratios, timelines, and compliance penalties.
   • Without certainty, private producers hesitate to invest in dehydration upgrades or logistics infrastructure.
4. Weak Feedstock Policy Integration
   • Agricultural policy still prioritizes sugar self-sufficiency, not biofuel yield.
   • No feedstock zoning or dual-use (sugar–ethanol) optimization, unlike Thailand’s “flex-crush” model.

7.5 Fiscal and Market Barriers

Excise Burden

• Excise on ethanol (IDR 20,000/L) is equivalent to ≈ USD 1.30/L, while gasoline excise is near zero.
• This reverses the economic rationale for blending, making domestic ethanol uncompetitive without subsidy.

Absence of Price Parity Scheme

• No reference pricing formula (e.g., biodiesel has MOPS-linked index).
• Pertamina must negotiate ethanol purchase price case-by-case, limiting scalability.

Foreign Investment Complexity

• Ethanol categorized under “chemical industry” → multiple licensing layers under OSS system.
• Feedstock sourcing and alcohol production face overlapping permits from MoI, ESDM, and MoF.

Export–Import Paradox

• Exporting industrial ethanol is easier than selling it domestically for fuel due to tax treatment.
• 2022 import surge (96 ML) showed how regulation failed to prioritize domestic supply security.

7.6 Coordination and Governance Challenges

Institutional Misalignment

• Bioethanol development crosses energy, agriculture, and industry—but no central authority manages integration.
• Inter-ministerial committees (e.g., National Energy Council) exist but lack operational budget or enforcement power.

Implementation bottlenecks:

1. Feedstock – Ministry of Agriculture controls cane allocation without ethanol priority.
2. Energy – ESDM can issue mandates but not fiscal incentives.
3. Finance – MoF controls taxation but no cross-sector coordination channel.
4. SOEs – PTPN (feedstock) and Pertamina (offtaker) operate separately, with different performance metrics.

Result: even when ESDM authorizes ethanol blending, logistical and fiscal chains lag 12–24 months behind policy announcements.

7.7 Infrastructure and Standardization Challenges

• Fuel Quality Standards: Indonesia currently uses SNI 7182:2020 for motor gasoline but lacks a parallel Ethanol Fuel SNI equivalent to ASTM D4806.
• Testing Infrastructure: Only two certified labs (BPPT Serpong, Lemigas) can test anhydrous ethanol for blending-grade purity.
• Depot Readiness: Of 200+ Pertamina depots nationwide, only 10 are ethanol-compatible (Java and Lampung).
• Safety Regulation: Transport and storage governed by Hazardous Material (B3) standards, not renewable-fuel protocols, increasing handling cost and complexity.

7.8 Strategic Challenges for the Next Five Years (2025–2030)

Writer’s Opinion

8.1 The Central Paradox of Indonesia’s Ethanol Industry

Indonesia’s ethanol industry stands at a historical crossroads:

• On one hand, it possesses the agricultural base, industrial infrastructure, and market size to become a biofuel powerhouse of Southeast Asia.
• On the other, it remains a feedstock-limited, policy-fragmented, and fiscally disincentivized sector, exporting industrial ethanol while importing petroleum.

This paradox is not due to lack of technology or investment appetite — but because of misaligned policy design and institutional inertia. For nearly two decades, the regulatory foundation (PerMen ESDM 32/2008) has provided legitimacy, yet without the economic instruments to make ethanol competitive with gasoline. Thus, Indonesia’s ethanol story is one of potential without propulsion — abundant promise restrained by systemic gaps.

8.2 Feedstock: The True Bottleneck

Every ethanol economy begins and ends with feedstock. Indonesia’s sugarcane yield averages 65–75 tons per hectare, compared to 90–100 tons in Thailand and 120 tons in Brazil. More crucially, its recovery ratio (7.5–8%) lags regional peers by 20–25%.

At that performance, each hectare of cane yields only 4,500–5,000 liters of ethanol equivalent, versus 6,500–7,000 L/ha in Thailand and over 8,000 L/ha in Brazil. Therefore, even if all Indonesia’s molasses were diverted to ethanol, it would still supply less than 10% of potential E10 demand.

The feedstock bottleneck is not purely agronomic — it’s structural:

• Cane acreage is static (~450,000 ha), squeezed between food and land-use competition.
• Fragmented smallholders (≈70%) have limited irrigation, mechanization, and financing.
• Industrial cane supply contracts rarely exceed one season, making long-term ethanol planning impossible.

The only way forward is feedstock diversification and integrated plantation–distillery models:

1. Dual feedstock corridors – Lampung (molasses + cassava), East Java (cane + sorghum), Sumatra (2G EFB & bagasse).
2. Ethanol–sugar flexibility – emulate Brazil’s “flex-crush” system to dynamically balance sugar and ethanol output depending on market signals.
3. National feedstock balance system – quarterly data on cane, molasses, cassava, and ethanol, enabling predictive planning rather than reactive crisis management.

Without addressing feedstock fragility, all downstream mandates will remain empty decrees.

8.3 Industrial Efficiency and Technological Lag

Technologically, Indonesia’s ethanol sector is 10–15 years behind regional peers. Most plants use conventional fermentation (48–52 hr cycle) and steam-based distillation with low heat recovery.

Only one facility (Enero) operates molecular sieve dehydration for fuel-grade output.

This results in:

• Higher energy consumption (2.2 MJ/L vs 1.5 MJ/L in Thailand).
• Higher cost base (USD 0.85–0.93/L vs USD 0.70 global average).
• Limited product flexibility (hydrated only, not anhydrous).

In global ethanol economics, scale + efficiency = competitiveness. Indonesia has neither: small average plant size (~30 ML/y) and high operational intensity. Modernization is no longer optional — it’s existential. Investing in dehydration columns, waste-to-energy recovery, and process automation could reduce unit cost by 15–20% within five years.

8.4 Infrastructure, Logistics, and Market Integration

Fuel ethanol is not just about distilleries — it’s about movement and mixing. Indonesia’s fuel distribution network, dominated by Pertamina, is extensive but not ethanol ready. Only 10–12 depots can currently handle ethanol safely. Blending remains manual or truck-rack, increasing contamination risk and cost.

For E5 or E10 rollout, blending must be inline, controlled, and certified. The U.S. and Brazil integrated ethanol into refinery streams early; Indonesia must retrofit its logistics chain from storage compatibility, water management, to QA laboratories if it wants nationwide blending credibility. This will demand capital coordination between Pertamina NRE, PTPN, and private producers.

8.5 Economics: The Price Parity Trap

Even before excise, ethanol’s production cost (≈USD 0.85/L) exceeds gasoline’s import parity price (≈USD 0.70/L). When combined with a Rp 20,000/L excise (~USD 1.30/L), ethanol becomes economically irrational for blending — nearly double the cost of gasoline on an energy basis.

The price parity trap is what has paralyzed ethanol’s energy transition. In its current form, ethanol can only survive as an industrial solvent or export good, not a domestic fuel substitute. Yet, paradoxically, the macroeconomic logic is strong:

Indonesia spends over USD 17–20 billion annually on oil imports. Replacing even 10% gasoline with ethanol could save USD 1.5–2 billion, while creating 50,000+ rural jobs in feedstock farming. The challenge is therefore fiscal alignment, not feasibility.

8.6 Sustainability and Global Positioning

Globally, the ethanol industry is transitioning toward carbon intensity (CI)-based value. Brazil’s RenovaBio, the U.S. RFS, and the EU’s RED III reward producers for every gram of CO₂ reduced. Indonesia, in contrast, lacks even a verified life-cycle emission baseline for ethanol.

If Indonesia wishes to export or attract green financing, it must:

• Establish national ethanol LCA factors (gCO₂e/MJ).
• Certify plants under ISCC/RSB sustainability schemes.
• Integrate ethanol into the Indonesia Carbon Exchange (IDXCarbon) as a tradable low-carbon fuel credit.

These are not environmental luxuries — they are economic prerequisites for future competitiveness.

8.7 Strategic Imperatives for Indonesia’s Ethanol Future

There are five imperatives to unlock the ethanol sector:

1. Feedstock Diversification
   • Integrate cassava, sweet sorghum, and biomass residues into ethanol supply chains.
   • Incentivize dual-use feedstock models between sugar mills and distilleries.
2. Industrial Modernization
   • Retrofit existing 96% distilleries with dehydration units to produce fuel-grade ethanol.
   • Introduce waste heat recovery, vinasse biogas, and cogeneration systems.
3. Supply Chain Integration
   • Develop ethanol-compatible infrastructure: storage tanks, inline blending systems, QA laboratories, and dedicated pipelines.
   • Expand E5/E10 corridor logistics with predictable investment roadmaps.
4. Fiscal Realignment
   • Remove or reclassify ethanol from excisable commodities for fuel use.
   • Create a parity formula indexed to MOPS gasoline to stabilize domestic prices.
5. Governance and Coordination
   • Establish a National Ethanol Steering Committee (NESCom) to synchronize feedstock, fiscal, and distribution policies across ministries.
   • Align PTPN and Pertamina under a unified “Sugar-to-Fuel” initiative to replicate the biodiesel success model.

8.8 Final Thought: Ethanol as an Economic Instrument, not a Commodity

Ethanol should no longer be viewed merely as “ethyl alcohol” — a regulated industrial substance — but as a strategic energy asset that delivers:

• Energy diversification (reduce gasoline imports).
• Rural economic stimulus (feedstock farming and processing).
• Carbon reduction (30–60% lifecycle cut vs fossil fuel).
• Industrial linkage (chemicals, CO₂, fertilizer, power).

Indonesia’s ethanol policy must shift from “control and caution” to “integration and innovation.”

• If treated as a commodity, ethanol will remain marginal.
• If treated as a national instrument — embedded in energy, agriculture, and industrial policy — it can reshape Indonesia’s rural economy and strengthen national energy resilience.

Conclusion

Overview: From Untapped Potential to Strategic Imperative

The ethanol industry in Indonesia, between 2020 and 2025, has remained a sleeping giant technically capable, geographically blessed, yet institutionally constrained. While total production hovered around 200 – 220 million liters per year, the country simultaneously imported over 35 million kiloliters of gasoline annually, a paradox for a resource-rich, agriculture-based economy. The mismatch between potential and performance is rooted in fragmented governance, fiscal misalignment, and limited feedstock diversification. However, recent developments Pertamina’s E5 pilot program, renewed investment interest by PTPN, and global carbon transition momentum signal a turning point. Ethanol is no longer merely a chemical product; it is becoming a strategic lever for energy security, rural industrialization, and carbon reduction.

Policy and Strategic Recommendations

Final Reflection: A Strategic Crossroads

Ethanol represents a rare convergence of Indonesia’s three national priorities:

1. Energy Independence – Reducing fuel imports and diversifying the energy mix.
2. Rural Industrialization – Creating agricultural value chains beyond raw commodities.
3. Climate Responsibility – Achieving measurable carbon reduction in line with NDC commitments.

However, its success depends not on additional studies or pilots, but on institutional courage and policy execution. Indonesia’s ethanol path is no longer about proving feasibility; it’s about governing delivery.
