Assessment of Stranded Marine Debris on Karimunjawa Island

Abstract

Marine Debris is a common problem in every tourism development area such as the Karimunjawa Islands. In accordance with the title, this study aims to identify the characteristics and density of debris around the Karimunjawa Islands. The method of taking data from this research is using direct-sampling on field observation technique by making transect columns to identify various debris compositions. Debris sampling was taken at four observation points namely Batu Topeng Beach (2 points), Batu Penganten Beach and Cemara Besar Beach. The results of field observation and debris sampling activities which has been done shows that the most common types of stranded marine debris found around the Karimunjawa Islands are plastic, wood, metal, glass and rubber. The highest density level of debris components obtained are the plastic type of debris found at Batu Penganten Beach with the value of density 4,18 plastic debris / m2 which is followed by the density level at Batu Topeng 1 Beach with a density value of 3,93 plastic debris / m2. The lowest level of solid debris density calculated is the type of metal found at Cemara Besar Beach, where the density level only reaches 0,02 metals / m2.
