PKM PEMANFAATAN LIMBAH AIR TAHU SEBAGAI BAHAN BAKAR ALTERNATIF BIOGAS PADA RUMAH TANGGA DI KECAMATAN TAMALANREA MAKASSAR

Abstract

The Community Partnership Program (PKM) titled Utilization of Tofu Wastewater as an Alternative Biogas Fuel for Households in Tamalanrea District, Makassar aims to assist partners in finding energy-saving solutions by utilizing tofu wastewater as an alternative biogas fuel. This initiative involves providing equipment and training to empower partners with the skills needed to process tofu wastewater into renewable energy for household use. The specific objective of this program is to ensure that the biogas equipment operates effectively within the partner’s production facility and surrounding community. The implementation method includes conducting surveys and interviews to identify the main problems faced by the partners. These findings are followed by the development and handover of biogas equipment as a solution. The final stage of the program involves evaluating its success by monitoring equipment usage and assessing the partners’ understanding and proficiency in operating the system. The test results show that the biogas equipment produced 3.68 liters of biogas with a stable blue flame lasting six minutes during combustion testing. The system achieved an efficiency rate of 48.61%. These findings demonstrate that tofu wastewater has significant potential as a biogas feedstock, supporting renewable energy development and contributing to environmental pollution reduction.
