As the world’s leading producer of palm oil, Indonesia stands at a critical crossroads of the global energy transition. The nation’s ambitious biodiesel mandates (such as B35 and the move toward B40) represent a significant step toward energy independence and carbon reduction. However, this shift has intensified a long-standing dilemma: the “Food-vs-Fuel” debate. Can a nation aggressively pursue biofuel targets without compromising the affordability and availability of domestic cooking oil? This challenge is the focus of a recent peer-reviewed publication in the journal Energy Nexus, which explores the systemic trade-offs inherent in Indonesia’s palm oil supply chain.

To move beyond a fragmented understanding of this issue, SEMS Lab researchers applied System Dynamics (SD) modeling. By utilizing a model-based policymaking approach, the team simulated the complex feedback loops between plantation productivity, refinery capacities, domestic food demand, and national energy mandates. This methodology allows for “What-If” scenario analysis, helping policymakers visualize how a decision in the energy sector—such as increasing the biodiesel blend—ripples through the system to affect household expenditures and industrial stability.

Key Highlights

  • The Price Interdependency: The research confirms that domestic cooking oil prices are highly sensitive to biodiesel mandates. When palm oil is diverted to fuel, the supply-demand balance for food shifts, necessitating integrated price-stabilization mechanisms.

  • Yield Improvement as a Leverage Point: Rather than relying on land expansion, which is increasingly restricted by environmental regulations, the study identifies plantation “intensification” (improving yield per hectare) as the most effective systemic lever for satisfying both food and fuel needs.

  • The Limits of land Expansion: The model illustrates that land expansion alone cannot sustain rising biofuel targets in the long term without creating significant ecological and economic friction.

  • Synchronized Policy Design: A key finding is the necessity of “de-siloing” government policies. Energy mandates must be designed in tandem with food security strategies to prevent market volatility and ensure industrial resilience.

The SEMS Perspective

This research reflects our commitment to moving from complexity to Clarity, from Insights to Impact. The “Food-vs-Fuel” debate is not a simple binary choice but a multifaceted system of interconnected variables. By applying systems thinking, we provide the Insight to Impact necessary to inform better decisions. Our goal is to ensure that Indonesia’s journey toward a green economy is both sustainable and socially equitable, fostering an industrial landscape that is resilient to global shocks while securing the basic needs of the population.
