RENEWABLE ENERGY TRANSFORMATION AS A MANIFESTATION OF ISTI'MAR AND AMANAH IN ISLAM: A PSO APPROACH IN NORTH SUMATRA

Rimbawati Rimbawati

Abstract


This study proposes an optimization model of the renewable energy mix in North Sumatra using the Particle Swarm Optimization (PSO) method. Five simulation runs were conducted with varying parameters to evaluate the optimal contribution of hydro, geothermal, biomass, biogas, and solar power plants. The simulation results show a consistent pattern, where hydropower contributes the largest share at around 48–52%, followed by geothermal at 18–21%, biomass at 10–13%, biogas at 7–9%, and solar at 6–8%. The fluctuations between simulations are relatively small, reaffirming the robustness of PSO in finding optimal solutions despite differences in initial parameters. The implementation of this model also demonstrates significant potential to reduce dependence on fossil energy, whose maximum capacity is maintained at approximately 1828 MW under the restriction scenario. From an Islamic perspective, the principles of isti’mar (prosperity and stewardship of the earth) and amanah (responsibility) reinforce that this transition is not merely technical but also carries ethical and spiritual dimensions, aligning with the maqasid al-shariah in preserving the environment (hifz al-bi’ah) and wealth (hifz al-mal).
