Waste Reduction Potential of the Waste Management Facility (TPST) in Gili Trawangan, Pemenang District, North Lombok Regency

The rapid growth of the tourism industry has led to an increasing number of visitors to small islands like Gili Trawangan in West Nusa Tenggara. However, this growth has also resulted in higher waste production. Gili Trawangan, as a prominent tourist destination, experiences significant impacts from this influx of tourists. In 2024, the island's waste production reached 5.1 tons per day, with only 4.6 tons being transported. Furthermore, waste management in Gili Trawangan remains suboptimal, with only 370 kg processed daily, including 200 kg of glass waste, 100 kg of plastic bottles, and 70 kg of paper waste. This study aims to analyze waste reduction potential using quantitative research methods, specifically mass balance analysis and recovery factor. The results are divided into three outcomes: reduction based on existing equipment, the addition of waste processing tools, and reduction through both equipment enhancement and worker capability improvements. Recommendations include the addition of one worker and three organic waste shredders. This would result in a total reduction of 3.9 tons per day, including 3.2 tons of organic waste, 377 kg of glass waste, 165 kg of plastic bottles, and 140 kg of paper waste.
