Pemanfaatan Limbah Kotoran Sapi Sebagai Pembangkit Listrik Tenaga Biogas Untuk Mesin Pengupas Kulit Kacang Berbasis IOT di Desa Pattiro Deceng Kabupatan Maros

Abstract

Along with population growth and the improvement of the community's economic status, energy demand continues to surge. The high dependence on natural resources such as oil, gas, and coal drives the urgency of developing alternative energy to ensure the fulfillment of human needs in the future. One potential solution is the utilization of biogas from cow manure waste, which is anaerobically processed into ready-to-use fuel for daily activities. This study aims to optimize the biogas storage facility owned by a partner from the Toba farmers group in Maddenge Hamlet, Pattiro Deceng Village, Maros Regency, as an energy source to drive a generator set (genset). The generated electricity is then allocated to operate a peanut peeling machine, considering that the majority of the local community works as peanut farmers who require work efficiency in the post-harvest process. The methodology for testing the biogas genset was conducted under two conditions, namely no-load and with the mechanical load of the peeling machine, at a constant gas pressure of 0.4 bar. In addition to analyzing generator rotation parameters to determine the optimal operational ratio, this study also tested the accuracy of an Internet of Things (IoT)-based electrical power monitoring system by comparing it against a conventional multimeter measuring tool. The comparison results showed a current value variation of up to 5% between the two measuring devices, which serves as an important reference in optimizing the performance and real-time monitoring of the biogas-based power generation system.
