Identifikasi Dan Analisis Kelimpahan Sampah Laut Di Pantai Manggar Sagara Sari Kota Balikpapan, Kalimantan Timur

Abstract

Human activities such as tourism and other activities carried out in coastal areas have the potential to cause impacts that disrupt the balance of the coastal ecosystem. One of the impacts of community activities that have the potential to disrupt the coastal environment is the spread of garbage. This research was conducted in the coastal area of Manggar Sagara Sari which aims to identify the type, composition and average abundance between types of marine debris. The transect was installed 100 m x 20 m and divided into 5 lanes of 20 m each. each lane is reassembled a sub transect box (5m x 5m) is placed in each of the randomly selected lanes. Data were analyzed using ANOVA-One Way. The types of waste identified are plastic waste, metal, processed wood, cloth, rubber, glass, paper, and other materials. The most identified amount of marine debris was plastic waste with a total of 367 items with a density of 2.94 items/m2. The composition of the amount of waste consists of plastic waste (85%), processed wood (5%), paper (3%), glass and other materials each (2%) while rubber, metal and cloth each (1%). There is a significant difference in the abundance of plastic waste compared to other types of marine waste with a p-value (0.000) < (0.05).
