Threats to the marine and coastal environment are increasing due to the increasing population and increasing exploitation of the population on the coast. If the garbage is thrown into the river or thrown directly into the sea, it will eventually result in a reduction in the beauty of the coastal area, the sea and the mangrove ecosystem. Inorganic waste with the type of plastic will not be separated from everyday life, due to the increasing number of people in the world. Therefore, the demand for and consumption of plastic-type materials is increasing and will continuously enter the land environment to the sea. Sampling is located at Tasik Ria Beach, Tombariri District, Minahasa Regency. The sampling time for marine debris in the mangrove ecosystem will be in August 2021. Inorganic waste sampling is carried out in the mangrove ecosystem by looking at the age of the month at the lowest low tide. Sampling used the line transect method or quadrant line transect and was carried out directly in the morning and it took one day until the tide started. Based on the research objectives, to identify inorganic marine debris found in the mangrove ecosystem of the Tasik Ria beach and analyze the total density of inorganic marine debris, both heavy and the amount laid on the mangrove ecosystem, research conducted at Tasik Ria Beach, Tombariri District, Minahasa Regency has obtained five types of waste. namely plastic, glass, metal, rubber and wood waste and their derivatives.
