Coastal debris is a global problem sourced from human or anthropogenic activities. Coastal debris has an influence on the growth of organisms in the waters and also for humans as users of coastal resources. The study was conducted on April 2018 in the Rumah Tiga Village, Teluk Ambon District to identify and to analyze coastal debris which consists of type, relative weight and density of the debris. Sample of debris was collected by using Line Transect method. The debris collected was filtered by using a 2.5 cm size sieve for macro debris and a 0.5 cm sieve for meso debris. The filtered debris was then identified based on the debris classification system of UNEP (United Nation Environment Program). The results showed that glass fragments and ceramics had the highest amount and density both in meso and macro debrises while building material in the form of rubble cement had the highest percentage of weight. Metal and plastic debris were also found in small amount, however both debrises are well known have negative influence on the growth of marine organisms.
