Abstract

ABSTRACT
West Semarang sub-district currently lacks adequate waste processing facilities, with Temporary Waste Collection (TPS) serving only as initial collection points before waste is transported to the final disposal site (TPA). This final project aims to analyze the existing waste management conditions in West Semarang sub-district
as a basis for planning a 3RWPS, which is expected to improve community waste management. The methods used include sampling based on SNI 3964:2025 and the Waste Wise Cities Tools Guidebook, Material Flow Analysis, and Simple Additive
Weighting (SAW) for determining organic waste treatment. The planned 3RWPS is designed to process organic waste through composting and fermentation, and inorganic waste through a pyrolysis machine, with a capacity of 19.4 tons/day,
resulting in only 10.47% of the total waste ending up in the landfill. The required investment is IDR 6,752,239,600, and management is planned to be carried out by the Karang Taruna of West Semarang sub-district, particularly in Tambakharjo Village. The proposed plan is expected to serve as an initial step toward more sustainable waste management in this sub-district.
