LIFE CYCLE ASSESSMENT (LCA) PENGELOLAAN SAMPAH PASAR WONOKERTO KABUPATEN MALANG

Abstract

Wonokerto Market is a traditional market in Malang Regency which is located on Jalan Raya Wonokerto-Bantur, Wonokerto Village, Bantur District, Malang Regency. Based on Malang Regent Regulation Number 8 of 2012, Wonokerto Market is included in Class II Regional Traditional Market which has a market area of 5,931 m2 with 94 shops, 96 powders, and 91 booths that are actively used for buying and selling. Waste handling at Wonokerto Market is carried out by container, collection, transfer, and transportation. The purpose of this study is to analyze the environmental impact from waste management in the existing conditions along with 3 (three) scenarios for waste management recycling, composting, and a combination of recycling and composting with a Life Cycle Assessment (LCA). The environmental impact categories analyzed from this waste management scenario include abiotic depletion, acidification, eutrophication, global warming, and ozone layer depletion. Life Cycle Assessment analysis was carried out using SimaPro software version 9.4.0.2 CML 2001 method. The interpretation of the Life Cycle Assessment (LCA) shows the results of the scenario with the lowest potential impact, namely scenario 3 (three) of waste recycling and composting. The relative contribution value in scenario 3 for the impact category is Abiotic Depletion of 459,754 kg Sb eq, Acidification of 273331,065 kg SO2 eq, Eutrophication of 29,204,356 kg PO4--- eq, Global Warming of 41,206633.4 kg CO2 eq, and Ozone Layer Depletion of 16,655 kg CFC -11 eq.
