Uji Kinerja Kompor Biomassa Multifungsi Berbasis Pemanfaatan Panas Buang Untuk Konversi Energi Listrik

Abstract

Biomass stoves are a renewable energy technology that utilizes agricultural waste as an alternative fuel to generate heat and electricity. The purpose of this study was to analyze the voltage, current, and electrical power generated, determine the battery charging duration, and analyze the thermal efficiency of multifunctional biomass stoves using various types of biomass. The study was conducted at the Agricultural Engineering and Biosystems Study Program Workshop, Faculty of Agriculture, University of North Sumatra, Medan. The research method used a complete randomized design (CRD) factorial and a non-factorial complete randomized design with the factors of fuel feeding interval (10, 15, and 20 minutes) and three types of biomass (rice husks, coconut shells, and sawdust). The parameters measured included voltage, current, electrical power, battery charging duration, and thermal efficiency. In this study, six TEGs were used, producing a maximum electrical power of 0.3599 watts, a voltage of 1.5858 volts, and a current of 0.2275 amperes. The fastest battery charging duration was 119 minutes using coconut shells with a 20-minute interval. The highest thermal efficiency was 11.8304% in the rice husk treatment.
