Abstract

The ecological integrity of many watersheds is declining due to land conversion, deforestation, and urbanization, which increase surface runoff, reduce infiltration, and trigger discharge instability. A quantitative evaluation that simultaneously links KRA, KAT, sediment load, flood frequency, and IPA parameters with water governance aspects to assess the degree of hydrological resilience in the archipelago. This study aims to assess hydrological resilience based on the carrying capacity of the water system in the Tiworo Watershed, Muna Island. The method used refers to the Minister of Forestry Regulation No. P.61/Menhut-II/2014 by measuring the variables of flow regime efficiency, annual flow coefficient, sediment load, flood intensity, and water use index. The results show that the carrying capacity of the Tiworo Watershed water system has a performance value of 96.25, which is categorized as moderate. This carrying capacity value can be interpreted as functionally having sufficient capacity, but is vulnerable to ecological and anthropogenic pressures.

Abstract

The Wanggu Watershed (DAS), located in the center of Kendari City, tends to experience development pressure due to uncontrolled land use along with increasing urban needs and infrastructure. The research aims to analyze the carrying capacity of the Wanggu Watershed based on water infrastructure investment and spatial utilization. The research method used is based on the Ministry of Forestry Regulation No. P.61/Menhut-II/2014 Concerning Monitoring and Evaluation of Watershed Management. The analysis data used includes population, value of water building investment, area of vegetation cover, area of protected areas in the watershed, and land area with a slope of 0–250. The results show that building investment in the Wanggu Watershed is in a medium urban area (224,225 inhabitants), the value of water building investment has a very high class (Rp. 73,89 billion), and the classification of the carrying capacity value of watershed building investment shows a poor class (125). Land use in the protected area of the Wanggu Watershed has a poor class (27%) due to the low level of protection in conservation areas, while cultivation areas show a very good class (106%), and the classification of the carrying capacity value of watershed land use shows a good class (87.5). This indicates that the use of area functions is in accordance with its designation. Strengthening aspects of spatial planning policies and controlling the use of protected areas need to be improved to ensure sustainable and continuous management of the Wanggu Watershed.
