Abstract

Macro-sized waste is not only found on the coastlines of densely populated islands, but also on the coastlines of small islands. Satonda Island is a small island in the eastern part of Sumbawa Island, West Nusa Tenggara Province, Indonesia. Although small, the island is an attractive tourist destination because it has a lake formed by the eruption of Mount Tambora. Therefore, the purpose of this study is to determine the abundance of garbage on the island due to the influence of tides. Waste data collection was carried out using the quadrant transect method which was carried out randomly along the coastline. Data were collected during high and low tide, and the parameters recorded were the amount and type of waste, size and shape of waste, coordinate points, transect length, and length of data collection. The results showed that waste on Satonda Island at high tide was dominated by rubber waste such as shoes and sandals weighing 1,457 g (33 items) with a density of 0.264 items/m3, while at low tide it was dominated by hard plastic waste weighing 3,972 g (147 items) with a density of 1.176 items/m3.
