Calculation of Waste Generation and Composition in Tegal City as an Effort to Increase Waste Reduction

Abstract

The generation of waste will increase along with the increase in population. Meanwhile, the composition of waste will change every year due to changes in the lifestyle and economic level of the community. Tegal is a densely populated city, and the accumulation of garbage in the city of Tegal in the last two years has increased by 38.9%. The existing waste management paradigm is still conventional so the amount of generation that enters the Final Disposal Site is still quite large. The purpose of this study is 1) to determine the generation and composition of waste in the Educational Area, offices, markets, and other public facilities. 2) find out the percentage of managed waste. The study began with surveys and interviews regarding the sources of waste and the existing conditions of waste management in the city of Tegal. The survey was conducted by reviewing the facilities of garbage bins, temporary shelters, and sources of waste. This research is quantitative in nature and becomes the basis for the proposed solid waste management design. Waste generation and composition were calculated using the SNI 19-3964-1995 method. The results showed that the waste generated was around 261.93 kg/day. Meanwhile, the composition of waste in Tegal City is dominated by organic waste by 66%. The rest is in the form of waste such as; plastic (15%), paper (13%), cloth & leather (4%) the rest is glass and metal, and others. The percentage of Tegal city waste that is managed is 88.8%, which is divided into two, namely: the first is waste handling with a percentage of 77.61% and the second is a waste reduction with a percentage of 11.19%. While the remaining 11.2% is still unmanaged waste.
