Pemetaan Bahaya Longsor dan Upaya Mitigasi di Kecamatan Cisarua, Kabupaten Bogor SARAGIH, VALENTINO WILLYFART Kecamatan Cisarua, Kabupaten Bogor, merupakan wilayah dengan kerawanan tinggi terhadap tanah longsor akibat topografi curam, curah hujan tinggi, kondisi geologi yang rentan, serta perubahan penggunaan lahan. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang memengaruhi bahaya longsor, menganalisis tingkat bahaya menggunakan pendekatan Multi Criteria Analysis (MCA) berbasis sistem informasi geografis (SIG), serta menyusun rekomendasi mitigasi. Parameter yang dianalisis meliputi kemiringan lereng, curah hujan, penggunaan lahan, litologi, jenis tanah, dan landform melalui pembobotan, skoring, dan analisis tumpang tindih spasial. Hasil penelitian menunjukkan bahwa Kecamatan Cisarua memiliki kelas bahaya longsor rendah (25,22 %), sedang (60,51 %), dan tinggi (14,26 %), dengan wilayah berlereng curam, bercurah hujan tinggi, dan penggunaan lahan yang tidak sesuai sebagai area paling rentan. Rekomendasi mitigasi meliputi perbaikan drainase, stabilisasi lereng, penguatan vegetasi, pengendalian alih fungsi lahan, serta peningkatan edukasi dan kesiapsiagaan masyarakat. Hasil penelitian diharapkan menjadi dasar penyusunan strategi pengurangan risiko longsor yang efektif dan berkelanjutan.; Cisarua District, Bogor Regency, is an area highly susceptible to landslides due to its steep topography, high rainfall, vulnerable geological conditions, and land use changes. This study aims to identify the factors influencing landslide hazards, analyze the hazard levels using a geographic information system (GIS) based Multi Criteria Analysis (MCA) approach, and formulate appropriate mitigation recommendations. The analyzed parameters include slope, rainfall, land use, lithology, soil type, and landform through weighting, scoring, and spatial overlay analysis. The results indicate that Cisarua District comprises low (25,22 %), moderate sedang (60,51 %), and high (14,26 %) landslide hazard zones, with steep slopes, high rainfall, and inappropriate land use identified as the most vulnerable areas. The proposed mitigation measures include improving surface drainage, slope stabilization, vegetation reinforcement, land use control, and enhancing community awareness and preparedness. The findings are expected to serve as a basis for developing effective and sustainable landslide disaster risk reduction strategies in Cisarua District.

Pemodelan Distribusi Aliran Air Lindi Fasilitas Pengolahan Sampah Bantargebang dan Sumur Batu Menggunakan Winflows Kusuma, Alana Willy Peningkatan timbulan sampah di TPST Bantargebang dan TPA Sumur Batu berpengaruh terhadap peningkatan volume air lindi yang berpotensi menimbulkan pencemaran lingkungan. Kondisi terkini menunjukkan terdapat kendala sistem pengolahan air lindi seperti kebocoran, fluktuasi debit, serta keterbatasan kapasitas. Penelitian ini bertujuan untuk menganalisis karakteristik hidrolik jaringan distribusi air lindi, menentukan sistem pengolahan yang mengalirkan air lindi dari IPAS 2 dan IPAS 3 menuju IPAL Lindi Bersama, dan menyusun rancangan distribusi aliran yang efisien. Metode penelitian meliputi observasi lapangan, pengumpulan data teknis, analisis hidrolik perpipaan, serta pemodelan menggunakan perangkat lunak Epanet dan Winflows. Analisis jaringan distribusi dilakukan dengan menentukan debit, elevasi, tekanan, dan waktu distribusi. Hasil pemodelan menunjukkan bahwa distribusi air lindi dengan sistem pompa berjalan optimal pada jam puncak. Simulasi pengolahan air lindi menunjukkan teknologi membran menghasilkan persentase air olahan yang tinggi sebesar 45-50%. Penelitian diharapkan menghasilkan rancangan sistem distribusi dan pengolahan air lindi yang andal.; The increasing amount of municipal solid waste at TPST Bantargebang and TPA Sumur Batu has contributed to a higher volume of leachate, which may pose environmental pollution risks if not properly managed. Current conditions indicate several constraints in the leachate management system, including pipeline leakage, flow rate fluctuations, and limited treatment capacity. This study aims to analyze the hydraulic characteristics of the leachate distribution network, determine an appropriate treatment system for conveying leachate from IPAS 2 and IPAS 3 to the Central Leachate Treatment Plant (IPAL Lindi Bersama), and develop an efficient leachate distribution design. The research employed field observations, technical data collection, pipeline hydraulic analysis, and hydraulic modeling using EPANET and Winflows software. The distribution network was analyzed based on flow rate, elevation, pressure, and distribution time. The modeling results indicate that the pump-operated distribution system performs optimally during peak operating hours. The leachate treatment simulation also demonstrates that the selected membrane technology is capable of achieving a high water recovery of approximately 45–50%. The proposed distribution and treatment system is expected to provide a reliable leachate management scheme.
