Carrying Capacity Analysis for Measuring Land Capability in Arid Area
Asep Saepulloh Institut Teknologi Bandung Indonesia , Maria Dolorosa Bhebhe Institut Teknologi Bandung Indonesia , Aang Anggara Institut Teknologi Bandung IndonesiaThe study of sustainable development in an area must include environmental carrying capacity (ECC). Measurement of environmental carrying capacity is needed to determine the limits of an area's ability to support individual behavior, such as consumption of natural resources and disposal of waste into nature. This study aims to evaluate the ECC analysis based on land capability in dry areas in East Nusa Tenggara as a contribution to spatial planning strategies. The results of this study show that Timor Tengah Selatan Regency, which is dominated by dry areas, has a land capability classification ranging from class I to III, or as much as 42% of the total area that can be exploited for agricultural and plantation activities. This research can be used as input for the 5-year revision cycle of the Timor Tengah Selatan Regency spatial plan so that land allocation in the RTRW is more in line with the land's carrying capacity.

Â This research aims to analyze the suitability of the Teluk Rasau Lake fish reserve based on environmental, social, economic, and cultural aspects and provide management recommendations for fish reserve based on its suitability. The research implemented from August to September 2023 in 3 (three) locations using the purposive sampling method. The suitability through the approach analysis of the function and effectiveness of the fish reserve area, considering parameters such as water depth, water quality, availability of aquatic plants as riparian vegetation, protection, water area, spawning, feeding, and nursery grounds for fish, rare/protected species, legality aspects, ease of access, usage conflicts, and the role of the community supervisory groups. Each parameter was scored based on its importance for the fish reserve. The analysis results of the function and effectiveness of the fish reserve show that its feasibility is quite appropriate, with a score of 26, indicating that the fish sanctuary is moderately functional and fairly effective. It was concluded that these categories showed optimal performance for the conservation goals of protecting rare/endemic fish species and increasing fish stocks for the surrounding waters. However, community supervisory groups participation involving the role was still low. Co-management-based fish reserve management is a suitable approach for the Teluk Rasau Lake fish reserve.
