Analisis Potensi Sampah Pasar Inpres Kalianda Sebagai Sumber Energi Terbarukan dilihat dari Aspek Timbulan, Komposisi dan Karakteristiknya

Abstract

This study aims to analyze the potential utilization of waste generated at the Inpres Market in Kalianda as a renewable energy source, based on waste generation volume, composition, and thermal-physical characteristics. Data were collected through field surveys, observations, interviews, and sampling following the Indonesian National Standard (SNI 19-3964-1994). The results showed that the total waste generated by market vendors reached 284.002 kg/day, with organic waste dominating at 70.7%, followed by plastic (15.9%) and paper (8.7%). Laboratory analysis of the waste characteristics revealed a moisture content of 81.71%, volatile matter of 16.83%, ash content of 0.97%, and fixed carbon of 1.03%. Using an average lower heating value (LHV) of 16.8 MJ/kg, the total thermal energy potential was estimated at 4,771.2 MJ/day. Assuming a thermal-to-electricity conversion efficiency of 25%, the resulting electrical energy potential is approximately 1,192.8 MJ/day or 347 kWh/day. These findings indicate that market waste, particularly organic-dominated waste, holds significant potential for development as a renewable energy source, while simultaneously offering a sustainable solution to waste management challenges.
