Abstract
One of the factors causing sea pollution is a large amount of plastic waste. Over the past 40 years, the world’s plastic production has increased by 25 times and the material recovered is no more than 5%. According to the World Bank in 2018, Indonesia is a contributor to 9 million tonnes of plastic waste annually. Plastic waste in the sea will be cut into smaller sizes or called microplastics, over 100 years. Microplastics have an impact that can save the lives of marine life. Globally, the growth of plastics has increased significantly, in the 1950s the amount of plastic reached 1.7 million tonnes and in 2014 it had increased to 299 tonnes. Muara Gembong is part of the downstream of the Citarum river in Bekasi Regency which has a dense population and has the potential to contribute to plastic waste in the sea. Based on the results of research, there are four types of microplastics found, namely fibres fragments, films and pellets. Microplastic characterizations found were polypropylene (PP), polystyrene (PS), nitrile, nylon, low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE). This can happen because of the dense population which will increase the activities of the community around the coastal area.
