Abstract

The Mamasa watershed is one of the important areas in the Mamasa–Saddang hydrological system, which has a strategic ecological function in providing ecosystem services. Changes in land cover, pressure on land use, and variations in geomorphological characteristics have the potential to affect the capacity to provide ecosystem services in the region. Therefore, a comprehensive understanding of the potential for ecosystem services is very important as a basis for sustainable development planning and the preparation of environmental carrying capacity studies within the framework of the Strategic Environmental Assessment (SEA). This study aims to describe and map the potential for ecosystem service provision in the Mamasa watershed, which covers the districts of Mamasa, Polewali Mandar, Pinrang, Tana Toraja, and Enrekang. The methods used include expert judgment for geomorphological and land cover assessment, which are then analyzed using a Pairwise Comparison Matrix and Geographic Information System. The results of the study show that the Mamasa watershed has 12 types of land cover and 8 types of geomorphology. In terms of food provision ecosystem services, the moderate category dominates at 53.77% and is mainly located in the upper reaches with an area of 25,463.67 ha. Clean water provision ecosystem services are also dominated by the moderate category at 56.18%, mainly distributed in the downstream area covering an area of 25,247.22 ha. For fiber provision ecosystem services, the moderate category dominates at 30.10% and covers the upstream area with an area of 24,649.19 ha. Meanwhile, biomass fuel ecosystem services show a dominance of the medium category at 30.10% with an area of 20,845.75 ha, which is also located in the upstream area. These findings provide a comprehensive spatial overview for sustainable natural resource management planning in the Mamasa watershed.

Abstract

Population growth is increasing beyond previous estimates. The world's energy needs are also extensive and continue to grow. This puts pressure on the energy available in nature in the form of biomass, and the decreasing fossil energy. So, alternative energy sources are needed that can be renewed in the form of Biofuel Sources. In addition, the development of biofuel energy source plants is a solution to restore environmental conditions. Based on this, it is necessary to identify the types of energy sources and the potential for developing biofuel energy source plants in the Bonehau Watershed ecosystem. The method used is non-experimental mapping based on Geographic Information Systems. The initial stage of introducing the identification of types of energy use by the community based on accessibility density classes. Furthermore, an analysis of the potential for developing biofuel plants, namely Nyamplung and Kemiri Sunan, was carried out using a land suitability approach. The Bonehau Watershed community generally uses LPG and firewood energy to meet household energy needs. Most people use more firewood energy than LPG because the watershed area has low accessibility, and the availability of firewood around the community's residence is limited. Analysis of Biofuel Plant Land Suitability in the form of Nyamplung Plants has the potential of 25% and Kemiri Sunan Plants 34% of the watershed area to be developed. The potential for developing these plants can handle 59% of the critical land for Nyamplung plants and 74% for Kemiri Sunan plants, from the total critical land area

Abstract

The Lake Tempe ecosystem is one of Indonesia’s national priority lakes that requires restoration due to severe sedimentation. The lake plays an important role in supporting regional economic resilience, social sustainability, and community livelihoods. The natural shallowing of the lake is caused by sediment transported by rivers flowing into the lake, including the Batu-Batu River. Previous oceanographic and limnological studies identified the highest accumulation of Total Suspended Solids (TSS) at the Batu-Batu River estuary. This study aims to analyze sediment conditions and formulate appropriate land-use directions as a sedimentation mitigation strategy in the Batu-Batu Watershed. Sediment accumulation was simulated using the Soil and Water Assessment Tool (SWAT) hydrological model. Land-use recommendations were developed by considering areas with heavy and very heavy sedimentation classes, land capability classes, 2020 land cover conditions, and the 2032 Spatial Pattern Plan. The simulation results show that sediment production in 2020 reached 1,233,509.04 tons/year, indicating a high sedimentation rate. Under the 2032 spatial planning scenario, sediment yield is projected to increase by 30.10% compared to existing conditions. However, the proposed land-use directions could reduce sediment yield by 66.17%. These findings indicate that the proposed land-use strategy can be considered in future regional spatial planning and watershed management policies.
