Composition of Coastal Waste in Ambon Bay Waters

Abstract

The results of activities originating from community activities include waste. Increasing population of Ambon City who settled in the area around the waters of the Ambon Bay increasingly increased resulting in an increase in the amount of waste produced. The purpose of this study is to determine the composition of coastal waste based on its type and determine the density and weight percentage of coastal waste in the waters of Ambon Bay. The research method used field observation methods with sampling locations on the coast of Rumahtiga-Poka and Laha, Sub-district of Teluk Ambon. The waste data obtained consisted of meso and macro waste, which were then identified and classified according to the United Nations Environment Program (UNEP) waste classification system. Analysis of waste data included density and percentage of specific gravity of waste. The results of the analysis of meso and macro waste densities in the two highest locations were owned by broken glass and ceramic waste with values ??ranging from 1.32 species / m² - 8.84 species / m². In the making process, glass and ceramics use heavy metal as a coating to make it glossier. If broken glass and ceramics enter the waters, there will be an increase in concentrations of heavy metals in the waters. The weight percentage of waste is dominated by building material waste in the form of cement which is found on the shores of Rumahtiga-Poka which are sourced from bridge construction activities. It can be concluded that the density of waste types in both observation locations is dominated by broken glass and ceramic waste, while the highest percentage of weight is owned by building material waste.
