Mikroplastic is a fragment of plastic that have size less than 5 mm. Microplastic mainly came from plactic debris as the result of degradation. The research about mikroplastic on sea urchine, water and sedimen had been done on Gili Labak Island Waters, Sumenep Regency, East Java. The purpose of this research is to know the amount, weight, and the type of microplastic on Gili Labak Island Waters and the correlation between each type of samples. The method that were used are random sampling and then laboratorium analyse. The part that had been tested on sea urchin are the gut which then add with KOH 10% as much as three times the sample weigh. The sample tha net using paper net for 100 sea water. For sedimen taken 50gr and added with NaCl as much as three times the weigh of the sample. The result from the netting than observe on stereo microscope to determine the type and the amount and then weighted on analytical scale. The result that obtained are the amount of microplastic on water are 189 particles with weight of 0,656gr, on sediment obtain 130 particle with weight of 0,0402gr and on sea urchin obtained 155 particle with weight of 0,0757gr. The types of microplastic that had been found are fragment, fiber, microfiber and film. From the anova test it happened to be know the signivicance value of both sample are above 0,05 which showed the difference between microplastic on each sample.
