Abstract

Government Regulation No. 37 of 2012 mandates that to prevent the decline in the carrying capacity of a watershed, it is necessary to increase the carrying capacity of the watershed. The carrying capacity of a watershed is the ability of a watershed to realize the sustainability and harmony of ecosystems and the increasing use of natural resources for humans and other living things in a sustainable manner. Minister of the Environment Regulation No. 17 of 2009 mandates that in carrying out the calculation of environmental carrying capacity, there are two carrying capacities that must be calculated, namely the carrying capacity of food and carrying capacity of water. Water carrying capacity is the potential contained in water and / or in water sources that can provide benefits or harms to human life and livelihoods and the environment. This study aims to analyze the carrying capacity of water in Pulubala Sub-watershed, Gorontalo District. This research uses the method of calculating the carrying capacity of water through the availability of water and the need for water which is calculated based on the guidelines for the preparation of environmental carrying capacity in the Minister of Environment Regulation No. 17 of 2009, and added with some calculations for the needs of agriculture (rice fields), industry, and animal husbandry. Pulubala watershed covers 4 sub-districts, namely Bongomeme District, Dungaliyo District, Pulubala District and Tibawa District. From the results of the analysis, the carrying capacity of water in Bongomeme District in 2016 was 0.59, in 2017 it was 0.70, in 2018 it was 0.69. Water carrying capacity in Dungaliyo District in 2016 was 0.46, in 2017 it was 0.54, in 2018 it was 0.46. Water carrying capacity in Pulubala District in 2016 amounted to 1.15, in 2017 amounted to 1.34, in 2018 amounted to 1.24. Water carrying capacity in the District of Tibawa in 2016 was 0.51, in 2017 it was 0.62, and in 2018 it was 0.57. The water carrying capacity in the Pulubala Sub-watershed is exceeded (carrying capacity <1) and conditional safety (carrying capacity between 1-2).
