Abstract

Rats pose a significant threat to rice farmers, attacking crops at all stages of growth, including storage, with the most severe damage occurring during the reproductive phase. In Bendung Village, Bendung District, rats have caused substantial losses, including crop failures, particularly due to unpredictable weather conditions. The proposed solution involves creating eco-friendly rodent repellents powered by solar energy. The activities include socialization, device design, technology implementation, and evaluation. Evaluation results indicate that 40% of farmers understand the operation of the rodent repellents using frequency waves, and 60% understand their environmental impact. This program has provided farmers with new knowledge about methods to repel harmful rodents.

Abstract

Household waste production, especially organic waste from yards and kitchens, often accumulates, causing disturbances to the surrounding environment. Organic waste can be processed in several ways, such as being processed into compost, eco-enzymes, fish feed pellets, and so on. One of the objectives of this community service program is to enhance community skills in processing yard and kitchen waste into various useful products. Organic waste from household kitchens, such as leftover vegetables and fruit peels, is processed into compost and eco-enzymes, thus reducing the waste burden on the environment. The conclusion obtained is that with the training on organic waste processing, community skills have improved and organic waste that is usually disposed of in the trash can be processed into various more beneficial products.

Abstract

Meningkatnya aktivitas perubahan penggunaan lahan di kawasan Universitas Trisakti menimbulkan permasalahan baru, di mana peningkatan jumlah area kedap air menyebabkan genangan saat terjadi hujan dengan intensitas tinggi. Untuk mengatasi permasalahan tersebut, dipilih solusi berupa pembangunan sistem ekodrainase dengan sumur resapan dan pemanenan air hujan pada gedung C Universitas Trisakti. Penelitian ini dilakukan untuk menganalisis penerapan teknologi ekodrainase sumur resapan dan pemanenan air hujan di gedung C Universitas Trisakti, dengan harapan dapat memberikan rekomendasi terkait pembangunan sistem ekodrainase yang tepat untuk gedung tersebut. Untuk sumur resapan, digunakan empat metode perhitungan, yaitu metode Sunjoto (1988), Litbang PU (1990), SNI 03-2453-2002, dan SNI 8456-2017. Hasil perhitungan dari keempat metode dibandingkan berdasarkan parameter diameter, kedalaman, debit, dan jumlah sumur resapan yang dibutuhkan. Sementara itu, untuk pemanenan air hujan, dilakukan perhitungan volume dan debit guna menentukan kapasitas tangki yang diperlukan. Berdasarkan hasil perhitungan, metode Sunjoto dipilih sebagai metode yang digunakan dengan radius sumur sebesar 0,7 meter, kedalaman rencana 1,5 meter, dan diperlukan sebanyak 31 sumur resapan berpori untuk menampung debit air hujan di gedung C Universitas Trisakti. Namun, pembangunan 31 sumur resapan tersebut sulit direalisasikan karena keterbatasan lahan yang tersedia. Oleh karena itu, perhitungan yang lebih memungkinkan adalah kombinasi empat sumur resapan dengan radius 0,7 meter dan kedalaman 1,5 meter di setiap sudut bangunan, sehingga dapat menambah cadangan air tanah sebesar 13% dari volume air hujan di atap bangunan, serta dilengkapi dengan tangki pemanenan air hujan berkapasitas 65 m³ atau berukuran 6,5 m × 5 m × 2 m.

Abstract

The Serayu Watershed is one of the critical watersheds in Central Java, particularly in the upstream. Aim: This study aims to assess the suitability of nature-based solutions (NBS) in flood risk reduction in the Serayu Watershed. Methodology and results: The collected data included the Serayu Watershed boundary and spatial datasets, consisting of a Digital Elevation Model (DEM), infiltration area map, soil erosion map, land use map, and slope map. The authors applied a spatial analysis method using the Geographic Information System (GIS) to integrate historical flood data, population density, topography, slope, geology, soil type, land use, water catchment area, water absorption area, groundwater basin, and erosion rate. The study found that within 10 years (2014-2023), 54 villages were exposed to flooding with a total area of ​​6,453.3043 ha or 8.010% of the area of ​​Purbalingga Regency. The analysis of land use changes from 2017 to 2022 shows a significant decrease in the area of ​​plantation forests-by 225,477.67 ha, from 323,979.26 ha to 98,501.58 ha. Conclusion, significance, and impact study: This study examines the regional characteristics and flood patterns of the Upper Serayu River in Central Java, Indonesia. Drawing on spatial analysis and hydrological data, the findings identified five NBS recommended for implementation: river floodplain restoration river and stream renaturation, building-related interventions, bioretention areas, and urban farming. These strategies align with local geormorphological conditions and offer sustainable approaches to flood mitigation. This study contributes to regional policy-making and supports the development of flood risk management in the Upper Serayu Watershed.
