Analysis of small island environmental carrying capacity in Panggang Island, Jakarta, Indonesia

Abstract

To support continuity of life, information on the availability of natural resources is needed. Natural resources need in a region must not exceed their availability. Panggang Island is a small island with an area of 13.76 ha and a population density up to 4,388 people in 2019. The land use of the island is intended as a residential area. With a small area and dense population, the ability of the environment to support life in Panggang Island is concerning. This study aims to determine the carrying capacity of water and land in Panggang Island. Water carrying capacity analysis is carried out by comparing the amount of water resource availability with standard water needs. The Thornthwaite Mather method is applied to calculate the water resource availability. Land carrying capacity analysis is based on a comparison of the amount of actual residential land with minimum space requirements of each individual according to the Indonesian National Standard (SNI 03-1733-2004). The results showed that Panggang Island has a very low carrying capacity for water and land. The water and land carrying capacity index reaches 0.12 and 0.98 respectively. This shows that the demands of residential land and water in Panggang Island are higher than the resources.
