ABSTRAC Pariaman Regency coastal area is affected by current and tide from Indian Ocean that contribute the presence of microplastic in that area. To understand the microplastic types and density, a research has been conducted in May-July 2019. There were 3 sampling sites (Pantai Mangguang, Pantai Ampalu and Pantai Gandoriah) and there were 3 plots (50x50 cm) placed in each site. Sediment inside the plot was scrapped 5 cm depth. The sediment was then sieved (5 and 1 mm mesh size), dried and soaked in 35% NaCl. The floating microplastics were then collected and identified using a dissecting microscope. Results shown that there were 4 types of microplastic present, they were film, fragmen, fiber and foam. The most common microplastic found was film (1,360item/m3). The density of microplastic found in the sampling site ranges from 400 - 1,840 item/m3. In the intertidal zone, the highest density of microplastic was found in the highest tidal level (2000 item/m3). Keywords: Plastic Pollution, Intertidal Zone, Sediment, Film.
