Analysis of Consigned Waste Generation and Planning for Trash Floating

Abstract

Environmental problems caused by indiscriminate waste disposal are very troubling to the local community. This problem occurs on Pasaran Island where waste enters from the Way Belau River and ends up in the waters and mangrove areas around Pasaran Island. This waste is sourced from the garbage of residents of the waterway area and consignment waste. Based on these problems, it is necessary to analyze the influx of waste as a first step in handling waste in the Way Belau River. Sampling refers to the journal, where the sampling process was carried out for one month with a frequency of twice a week by installing nets on both sides of the river for six hours. Measurement of the weight and volume of waste produced was carried out based on SNI 19-3964-1994. The results of the study showed that the average amount of waste entering the Way Belau River was 19.33 kg/day. The amount of waste generated in the research location can be caused by several factors such as the width of the river, the net used, the weather, the sampling location, and the activities of the surrounding community. The largest to smallest component of waste composition starts from organic waste (47%), plastic waste (34%), hazardous waste (8.11%), textiles (7.17%), paper (2.17%), rubber (1.71%), glass (0.28%), and metal waste (0.08%). Trash floating is a tool that will be designed to block the entry of river waste into the sea. The cost budget plan in making trash floating in the Way Belau River with a width of 8 m requires a cost of Rp. 8,898,420.
