Abstract

Estimation of surface run-off in karst watersheds has not been widely carried out and the estimation method is generally developed for non-karst watersheds. This study aims to analyze the accuracy of estimation of river discharge at the outlet of the Karst Biringere Sub-watershed using the modified Soil Conservation Service Curve Number (SCS-CN) method and analyzed the impact of land use change on river discharge at the outlet of the Karst Biringere Sub-watershed. Modification of the SCS-CN method in estimating direct flow at the outlet of the Beringere Sub-watershed is influenced by the similarity of rainfall and direct flow fluctuation of river discharge. The modified SCS-CN method provides satisfactory direct flow estimation when rainfall with observed direct flow of river discharge forms a linear relationship with a strong correlation. Changes in land use with reduced forest cover into mining areas result in increased run-off and reduced storage, the larger the forest land becomes mining areas, the greater the increase in run-off and reduction in storage. Reclamation of the former mining area to be a forest reduces run-off and increases water storage.

Abstract

Pemanfaatan Danau Lido akan terus berkembang terutama pada aspek pariwisata, karena Rencana Tata Ruang Wilayah (RTRW) Kabupaten Bogor 2016-2036 telah menetapkannya sebagai kawasan pariwisata dan dalam Peraturan Pemerintah Nomor 69 tahun 2021 sebagai kawasan ekonomi khusus pariwisata. Pada saat yang sama terjadi penumpukan sampah di sempadan, masuknya limbah di perairan dan sedimentasi menjadi permasalahan yang ada saat ini. Penelitian ini bertujuan untuk meyusun strategi pengelolaan agar keberlanjutan danau Lido dapat dipertahankan dalam menghadapi perkembangan. Melalui metode SWOT penelitian ini mengidentifikasi faktor internal dan eksternal yang ada di danau Lido, dengan cara menganalisis karakteristik kondisi biofisik danau dan menganalisis preferensi dan partisipasi masyarakat di sekitar danau. Hasil penelitian menunjukkan internal factor evaluation dan external factor evaluation danau Lido berada pada kuadran V, yaitu bentuk strategi mempertahankan dan memelihara. Berdasarkan matriks SWOT ada 6 strategi pengelolaan yang direkomendasikan yaitu (1) Ekowisata sebagai dasar pengembangan pariwisata, (2) Menerapakan dan menata sistem budidaya ikan KJA ramah lingkungan, (3) Penanganan sedimentasi di perairan danau, (4) Membuat arahan desain bangunan di sempadan danau, (5) Penanganan penyebab degradasi danau di daerah tangkapan air danau, (6) Menyediakan sarana dan prasarana pengendalian sampah.

Abstract

The redevelopment of the slum area in Community Unit CU (Rukun Warga/RW) 07 Babakan Raya, Dramaga District, is a strategic step to reduce slum conditions while improving the quality of the area's infrastructure. This study aims to identify and analyze the existing slum conditions based on basic infrastructure, land use, building density, and environmental quality, and to develop a spatial planning concept based on spatial analysis to produce an adaptive and sustainable site plan. The methods used include a physical survey in the field, involving 81 respondents through crowdsourcing, and a Weighted Overlay analysis based on the criteria outlined in the Regulation of the Minister of Public Works and Public Housing No. 14/PRT/M/2018. The results showed that 56% of respondents identified building quality as the main factor contributing to slum conditions, followed by drainage problems at 23%. The spatial analysis identified a severe slum area of 9.220 m² located in the southern part of CU 07, while the mild slum area reached 61.210 m². The projected population of Babakan Raya in 2044 is estimated to accommodate 6.500 people, with a density of approximately 573 people per hectare. As a technical response, a spatial plan for the development of the area was prepared in accordance with SNI 03-1733-2004 to improve building layout, drainage systems, and environmental quality in the future. Implementation of this plan is expected to create a healthier, safer, and more sustainable residential environment.
