Abstract

Abstrak: Ketika memasuki musim kemarau, beberapa wilayah di Kabupaten Malang mengalami kesulitan air untuk kebutuhan hidup sehari-hari, salah satunya Dusun Sumberwaluh, Desa Pringgodani, Kecamatan Bantur. Kegiatan ini bertujuan untuk meningkatkan pemahaman peserta kegiatan terkait potensi air tanah sebagai langkah awal untuk mengatasi kekeringan pada lokasi pengabdian. Metode pelaksanaan adalah sosialisasi, sedangkan mitra kegiatan yaitu Yayasan SEMAIN dan warga setempat. Kegiatan sosialisasi diikuti oleh 5 Dosen, 3 mahasiswa, 4 mitra dari yayasan SEMAIN, dan 57 mitra sekaligus peserta dari warga setempat. Evaluasi untuk mengukur pengetahuan peserta dilakukan melalui pertanyaan langsung sebanyak 3 pertanyaan. Indikator keberhasilan kegiatan ini adalah peserta memiliki pengetahuan tambahan terkait potensi sumber air tanah pada daerah mereka. Hasil yang dicapai yaitu peserta memperoleh pengetahuan baru, dimana mayoritas peserta mampu menjawab 2 dari 3 (66,6%) pertanyaan terkait materi sosialisasi yang diberikan. Secara ekonomi, kegiatan investigasi sumber air tanah menghabiskan biaya sekitar 30 juta, sedangkan pembuatan sumur bor sekitar 70 juta (total 100 juta). Biaya tersebut diberikan secara gratis kepada masyarakat setempat sebagai bentuk kepedulian terhadap sesama.Abstract: When entering the dry season, several areas in Malang Regency experience water shortages for daily needs, one of which is Dusun Sumberwaluh, Pringgodani Village, Bantur District. This activity aims to increase participants' understanding of groundwater potential as an initial step in overcoming drought at service locations. The implementation method is socialization, while the activity partners are the SEMAIN Foundation and local residents. The socialization activity was attended by 5 lecturers, 3 students, 4 partners from SEMAIN Foundation, and 57 partners and participants from local residents. Evaluation to measure participants' knowledge is carried out through 3 direct questions. The success indicator of this activity is that participants have additional knowledge regarding the potential of groundwater sources in their area. The results achieved were that participants gained new knowledge, where the majority of participants were able to answer 2 out of 3 (66.6%) questions related to the socialization material provided. Economically, groundwater source investigation activities cost around 30 million, while drilling wells cost around 70 million (total 100 million). These costs are provided free of charge to the local community as a form of concern for others.

Abstract

Abstrak: Pengabdian ini bertujuan mengedukasi masyarakat tentang upaya mitigasi terhadap bencana kekeringan di wilayah desa setempat sehingga meningkatkan softskill masyarakat dalam menghadapi potensi bencana alam tersebut serta hardskill dalam pengelolaan air bersih yang efisien. Metode yang digunakan yaitu metode resistivitas sounding atau VES (Vertical Eletric Sounding). Kegiatan pengabdian diikuti oleh Tim Pengabdian Teknik Geofisika Universitas Brawijaya sekitar 5 orang dengan profil sebagai ahli geofisika dan ahli geologo, Yayasan SEMAIN sekitar 10 orang dengan kemampuan dalam menyelaraskan hubungan para ahli dan warga serta membantu dalam penyuluhan air bersih dan warga setempat sebagai pelaku dalam kegiatan. Hasil pengabdian diwujudkan dalam bentuk peta persebaran air tanah yang dapat digunakan dalam acuan pengeboran sumber mata air. Pemberian materi berupa ceramah dan praktik umum secara langsung dan berkala sehingga dapat meningkatkan kesadaran akan pentingnya air bersih. Tingkat persente pemahaman masyarakat sekitar rata-rata 19.2% sebelum dilakukan pengabdian dan meningkat rata- rata menjadi 89% setelah dilakukan pengabdian. Hal ini dibuktikan dengan penggunaan air bersih yang lebih efisien dibanding sebelumnya seperti penampungan air hujan perubahan kebiasaan penggunaan air bersih.Abstract: This community service aims to educate the community about mitigation efforts against drought disasters in the local village area so as to improve the community's soft skills in dealing with potential natural disasters as well as hard skills in efficient clean water management. The method used is the resistivity sounding method or VES (Vertical Electric Sounding). The community service activity was attended by the Brawijaya University Geophysical Engineering Community Service Team of around 5 people with profiles as geophysicists and geologists, the SEMAIN Foundation of around 10 people with the ability to harmonize the relationship between experts and residents and assist in clean water counseling and local residents as actors in the activity. The results of the community service are manifested in the form of a groundwater distribution map that can be used as a reference for drilling springs. The provision of material in the form of lectures and general practices directly and periodically so as to increase awareness of the importance of clean water. The level of understanding of the surrounding community averaged 19.2% before the community service was carried out and increased to an average of 89% after the community service was carried out. This is evidenced by the use of clean water that is more efficient than before such as rainwater collection changes in clean water usage habits.

Abstract

Forecasting earthquakes is still one of the most difficult problems in geophysics, mainly because seismic activity is irregular and often influenced by many factors that interact in complex ways. In this study, we develop a leakage-controlled hybrid ensemble model that combines CatBoost, LightGBM, XGBoost, and Gradient Boosting to predict five earthquake parameters: magnitude, depth, latitude, longitude, and a scaled inter-event interval in Northern California. These models were trained using USGS earthquake data ranging from 1900 to 2025 (M ≥ 4.0), with a process designed to prevent time leakage through strict time separation, a moving window feature, and prospective validation. Overall, the hybrid models produced consistently low MAE and RMSE values ​​and very high R² values ​​(above 0.99) for all target variables. While the estimates performed impressively, the results should be interpreted in a probabilistic context, with recognition of the inherent uncertainty of seismic processes. The framework proposed here provides a clear and replicable approach that can support the development of systems for more reliable short-term earthquake forecasting
