Oil palm waste in the South West Aceh, Indonesia region, has the potential for renewable energies to replace fossil energy. On the basis of previous studies, the mixture of EFB, fiber and shells into bio-try briquettes had an average calorific value of 5000 calories per gram. In this study, the authors explored the potential of bio-try briquettes. Especially for the South West Aceh (Barsela) Region, a Bio-try briquette can generate electricity of 586.152 GWH, meet electricity consumption in Barsela of 584.57 GWH, and electricity surplus of 1.582 GWH. On the basis of the economic feasibility analysis, it was demonstrated that the Internal Rate of Return (IRR) is 22.58%, which surpasses the set interest rate of 12%, the net profit (NBC ratio is 34.39 > 1), and the principal return point (BEP) is below 1 year (< 0.034 years). As for the environmental aspect, the solid waste used can be reduced by 10.94% or 100800 tons per year. The environmental impact caused by the presence of bio-try briquette on the global warning potential (kg CO2 eq) or greenhouse gases on the third mixture of waste is 77,000 kg per day or 77 tons per day.
