Pengembangan Sistem Pengelolaan Sampah di Kota Prepare

Abstract

Waste is often viewed as a problem in human life. On one hand, waste is considered as having no economic value, thus disposed; on the other hand it is viewed as useful material. The purpose of this research was to develop a waste management system in Parepare. It was conducted in a region of 99.33 km² consisting 21 villages. The location was determined on the basis of population density, resulting in the villages of: Wattang Soreang, Labukang, and Lumpue. The primary data was obtained from 100 respondents, and the secondary data from various related institutions. To determine the amount of waste and the age of the Final Disposal Area, the model of analysis system, Powersim was applied; whereas a laboratory analysis was used to determine the quality of shallow well water as clean water. The respondent profile shows that 87.0% respondents are males and 13.0 % females. In terms of education level, around 11.0% respondents are of elementary schools, 23% of junior secondary schools, 52 % of senior high schools, and 14.0% of tertiary education. 64.0% respondents are state civil servants and National Army, 15.0% self-employed, 12.0% farmers and fishermen, and 9.0% laborers. The income level shows that 3.0% respondents receive less than Rp 750,000/month, 22.0% between Rp 750,000 and Rp 1000,000/month and 75.0% more than Rp 1000,000/month. The data on the numbers of family members shows that 42.0% of respondents have less 5 members, 58.0% more than 5 members. The types of waste are 7.2% used paper, 75% leaves and vegetable waste, 12.8% plastic bags, and 5.0% others. The disposal methods include: 74% thrown into garbage bins, 3,0% burned, 11.0% thrown into rivers, and 12,0 % disposed to the sides of streets. The result of analysis showed that the sample water of shallow well was not suitable for the source and direct use of clean drinking water. The parameters have exceeded the threshold or limit of standard quality of clean water: turbidity, phosphate, COD, total coliform and Escherichia coli. At present, the waste management system is not optimal because of limited vehicles of waste removal, field workers, and waste collecting facilities, thus only as much as 256 m³/day of total waste produced every day is disposed to the Final Disposal Area (FDA). The amount of waste in 2012 is estimated to be 114.124 m³/year. Based on the using age of FDA and people participation in sorting and management of organic and inorganic wastes by the government by applying the 3 R+ 1P pattern and a simulated model, the analysis resulted in a zero for 2002.
