Abstract

The Karangpucung Housing Area in Purwokerto Selatan District frequently faces local flooding problems due to increased rainfall intensity and limited water absorption areas caused by urbanization. This condition is further exacerbated by the community’s lack of understanding regarding the importance of water conservation and simple technologies for flood mitigation. To address this issue, this community service activity was conducted with the aim of providing education and concrete action through socialization and the construction of rainwater infiltration wells. The activity was carried out from April to May 2025 using the Participatory Rural Appraisal (PRA) approach and a community-based approach to encourage active community involvement. The activity stages included site surveys, socialization and outreach, technical training on infiltration well construction, and monitoring and evaluation. The results showed that 50 residents actively participated in the socialization and training activities, and 10 infiltration wells were successfully built at strategic locations previously prone to flooding. Residents also demonstrated improved understanding of the function of infiltration wells and the importance of water conservation as part of hydrometeorological disaster mitigation. Testimonials from residents indicated a significant reduction in flooding following the well construction. This program demonstrates the effectiveness of an educational and participatory approach in encouraging behavioral change among the community. Moving forward, regular maintenance strategies and the involvement of other stakeholders are needed to ensure that this program can be replicated and expanded to other areas facing similar issues.

Abstract

Program pengabdian masyarakat ini bertujuan untuk meningkatkan akses masyarakat pesisir terhadap air bersih melalui penerapan teknologi pengolahan air berbasis filtrasi sederhana di Desa Papringan, Kecamatan Banyumas, Kabupaten Banyumas. Permasalahan utama yang dihadapi warga adalah rendahnya kualitas air sumur akibat tingginya tingkat kekeruhan, kandungan logam berat, serta kontaminasi mikroba yang disebabkan oleh intrusi air laut dan limbah rumah tangga. Kegiatan ini dilaksanakan dengan pendekatan partisipatif berbasis komunitas yang melibatkan warga dalam seluruh tahapan, mulai dari perencanaan, pembuatan, hingga pemeliharaan alat filtrasi. Sistem filtrasi yang dikembangkan menggunakan bahan lokal seperti pasir silika, arang aktif, ijuk, dan kerikil, dengan desain yang mudah diterapkan dan berbiaya rendah. Hasil pengujian menunjukkan penurunan kekeruhan air sebesar 93,8% dan kandungan Escherichia coli hingga 96%, menjadikan air layak digunakan untuk kebutuhan rumah tangga. Selain peningkatan kualitas air, terjadi pula peningkatan literasi masyarakat terhadap sanitasi dan kesehatan lingkungan sebesar 36,8%, serta penurunan pengeluaran air bersih rumah tangga hingga 60%. Pembentukan Kelompok Masyarakat Peduli Air Bersih menjadi langkah strategis dalam menjaga keberlanjutan program melalui sistem perawatan mandiri berbasis gotong royong. Kegiatan ini tidak hanya memberikan dampak teknis dan sosial, tetapi juga mendukung pencapaian Sustainable Development Goals (SDGs) poin ke-6 tentang air bersih dan sanitasi layak. Dengan demikian, penerapan teknologi filtrasi sederhana berbasis bahan lokal terbukti efektif, inklusif, dan dapat direplikasi di wilayah pesisir lain di Indonesia sebagai model pengelolaan air bersih berkelanjutan.

Abstract

The estuary functions as a discharge from the river, especially when it floods into the sea. The movement of currents from the sea and also the flow of water from upstream causes sedimentation problems in the estuary. Jetty building planning is required for handling sediment at the estuary of the Serayu River, which is planned with 35721 m2 construction area of a pair Wind data analysis for 10 years is carried out using software WRPLOT, AUTOCAD, and Google Earth. Concrete quality for making tetrapod using concrete (f’c) 31.2 MPa. The tetrapods used have a weight, width, height of 7.6 tons, 2.69 m, and 2.24 m, respectively. Geotextiles used in the jetty building design are 44781.68 m long. Security of the Serayu River estuary requires two pairs of the jetty, the jetty to the right of the estuary requires 778 m length and 34.6 m width, while the jetty to the left of the estuary requires 560 m length and 34.6 m width. The budget plan for the construction of a jetty for handling sediment at the estuary of the Serayu River is IDR 438,708,114,000.00.

Abstract

An earthquake is one that occurs as a result of a sudden shift in the soil layer below the earth's surface. Purwokerto as the city of Banyumas Regency is a city that is currently trying to develop as well as other big cities in Indonesia. The lecture building is a public service facility in terms of education for the community As the lecture building must be able to provide feasibility and comfort so that activities inside and outside the lecture building become comfortable. This aims of the reasearch to assess the vulnerability of several buildings at Wijayakusuma University to earthquakes. To find out the feasibility of the building, the analysis approach was carried out using the RVS method contained in FEMA 154, besides that the load calculation was carried out using SAP 2000 modeling with the 3D Response Spectrum method. The results showed that the multi-storey buildings at the University of Wijayakusuma Purwokerto were safe against earthquakes when assessed by the RVS method, whereas when assessed by the 3D response spectrum method in accordance with SNI 1726-2019 these buildings were less safe for fundamental natural vibration times, but for the third loading the building is safe.
