The observation and direct sampling, as well as laboratory tests of this research was conducted from June until October 2018. This study aims to determine the existence of microplastics in the sediment of water bodies in Kupang and Rote Districts based on the number, type, size and abundance of microplastics. The data used in this study include the type of sediment, microplastic abundance and the characteristics of the data collection area. Microplastics are plastic particles sized less than 5 mm, and in our research, were divided into 4 types: manifold fiber, fragment, film and pellets. Herein, 849 particles of microplastic were found: 635 fibers, 160 particle fragments, and 54 particle films. The primary influencing factor for microplastic deposition is the sedimentary texture itself. Sediments of a coarse type do not capture as much microplastic as do sediments of a finer texture. Data collection area characteristics also affect accumulation.

Rapid development in the tourism sector of Pangandaraan raises various problems such as environmental degradation, environmental pollution and waste problems. Microplastic pollution in the oceans is a type of hazardous waste, with microscopic plastic particles less than 5 mm in size. Generally, easy-to-find microplastics include fragments, films, and fibers. Microplastic abundances are found in deep sea areas similar to those in the intertidal area. The purpose of this research is to know the microplastic composition which is sedimentation in various types of sediments and the factors that influence the changes to the microplastic sedimentation in the Pangandaran waters. This research uses the survey method. The most common microplastic particles in station 2 were 12.622 particles (fibers and fragments) and the lowest was found in station 4 of 1.809 particles (fiber, fragment and film). The highest number of microplastic particles trapped in mesh size sediment between 106 µm – 250 µm. Current, waves and tides are factors that cause microplastic movement in the sea. The distribution of microplastic particles is influenced by oceanography factor, density, shape and size of microplastic.
