Abstract

Research using satellite imagery of gravity data has been conducted in the Dampit District, Malang Regency, East Java Province. This research was conducted to identify areas vulnerable to landslides. The results of this research can serve as a basis for the government to develop effective landslide disaster mitigation policies, thereby minimizing the losses incurred. The data used is TOPEX satellite gravity data in the form of Free Air Correction data, and supported by landslide vulnerable areas data from the InaRisk satellite. The research area is 23 km x 16 km with 2 km spacing between points and 184 measurement points. Furthermore, the research area is divided into four areas: Area A1, Area A2, Area A3, and Area A4.  The residual anomaly value in the study area is between 82.7 mGal to 142.4 mGal. The residual anomalies are more variable due to the local nature of the anomalies. The correlation between the residual anomaly value and InaRisk satellite image data shows that Area A4 is the most vulnerable to landslides, especially if there is a trigger such as an earthquake.  This is because Area A4 has a low-density value, a large fault, and is the contact area between the Mandalika Formation and Wuni Formation.

Abstract

Abstrak: Salah satu penyebab menurunnya produktivitas tambak di Kelurahan Blandongan Kota Pasuruan yaitu penurunan kualitas lingkungan tambak karena tingginya ketergantungan terhadap pakan dan probiotik pabrikan yang mahal serta kurangnya inovasi budidaya ramah lingkungan. Kegiatan ini bertujuan untuk meningkatkan pengetahuan petambak tentang penggunaan probiotik alami berbahan rempah sebagai alternatif yang lebih murah dan ramah lingkungan. Kegiatan disampaikan dengan metode dialog interaktif dan praktik, diikuti oleh 3 dosen dan 3 mahasiswa Universitas Brawijaya. Sebagai mitra yaitu Kelompok Pembudidaya Ikan Banyu Urip sebanyak 27 peserta dan Dinas Perikanan Kota Pasuruan sebanyak 10 peserta. Evaluasi kegiatan menggunakan kuesioner dengan 6 pertanyaan untuk mengukur tingkat pemahaman peserta sebelum dan sesudah kegiatan. Hasil evaluasi menunjukkan bahwa lebih dari 80% peserta belum mengetahui kandungan dan proses pembuatan probiotik alami. Setelah sosialisasi, sebanyak 95% responden menyatakan telah memahami fungsi probiotik, kandungan bahan aktif, serta tahapan pembuatannya. Dengan pendekatan edukatif berbasis dialog interaktif dapat meningkatkan kapasitas petambak dalam mengadopsi teknologi tepat guna dan berkontribusi pada keberlanjutan produktivitas tambak tradisional.Abstract: One of the causes of declining pond productivity in Blandongan Village, Pasuruan City is the decline in the quality of the pond environment due to the high dependence on expensive feed and probiotics and the lack of environmentally friendly cultivation innovations. This activity aims to increase farmers' knowledge about the use of natural probiotics made from spices as a cheaper and environmentally friendly alternative. The activity was delivered using interactive dialog and practical methods, attended by 3 lecturers and 3 students of Universitas Brawijaya. The partners were the Banyu Urip Fish Farmer Group with 27 participants and the Pasuruan City Fisheries Service with 10 participants. The evaluation of the activity used a questionnaire with 6 questions to measure the level of understanding of the participants before and after the activity. The evaluation results showed that more than 80% of the participants did not know the content and process of making natural probiotics. After the socialization, 95% of respondents stated that they understood the function of probiotics, the content of active ingredients, and the stages of making them. This proves that an educative approach based on interactive dialog can increase the capacity of farmers to adopt green technology and contribute to the sustainability of traditional pond ecosystems.

Abstract

Abstrak: Seiring bertambahnya usia, lansia rentan mengalami berbagai masalah kesehatan gigi dan mulut. Umumnya masyarakat beranggapan bahwa masalah gigi merupakan bagian alami dari proses penuaan, dan lebih parah jika masyarakat beranggapan bahwa masalah gigi dan mulut merupakan hal yang sepele. Sehingga kegiatan pengabdian ini bertujuan untuk memberikan edukasi kesehatan dan penyakit mulut bagi para lansia terkait penyakit sistemik. Pelaksanaan kegiatan dilakukan dengan metode sosialisasi kemudian dilanjutkan dengan pemeriksaan kesehatan. Tim pelaksana kegiatan terdiri dari 7 Dosen FKG UB, 20 Mahasiswa FKG UB, sedangkan mitra sekaligus peserta sebanyak 44 orang lansia yang berasal dari Desa Sumberejo dan Desa Kalisongo. Sistem evaluasi menggunakan kuesioner untuk mengukur tingkat pemahaman peserta sebelum dan sesudah kegiatan. Hasil evaluasi menunjukkan adanya peningkatan pemahaman peserta yang signifikan, seperti pengetahuan tentang diabetes mellitus dan dampaknya terhadap kesehatan mulut. Responden yang menyatakan "tahu," awalnya sebanyak 11 responden meningkat drastis menjadi 33 responden (50%). Secara garis besar kegiatan edukasi tentang kesehatan gigi dan mulut dalam kegiatan pengabdian ini mampu memberikan dampak positif. Tim pengabdian berharap, kegiatan pengabdian ini dapat mendorong perubahan perilaku menuju praktik kebersihan gigi dan mulut yang lebih baik.Abstract: As people age, the elderly become increasingly susceptible to various dental and oral health problems. Generally, people assume that dental problems are a natural part of the ageing process, and it is worse if people assume that dental and oral problems are trivial. So this community service activity aims to provide health and oral disease education for the elderly regarding systemic diseases. The implementation of the activity was carried out using the dissemination method and then continued with a health check. The activity implementation team consists of 7 FKG UB lecturers, 20 FKG UB students, while the partners and participants are 44 elderly people from Sumberejo Village and Kalisongo Village. The evaluation system uses a questionnaire to measure participants' level of understanding before and after the activity. The evaluation results showed a significant increase in participants' understanding, such as knowledge about diabetes mellitus and its impact on oral health. Respondents who stated "know," initially 11 respondents, increased drastically to 33 respondents (50%). Generally, educational activities about dental and oral health in this community service activity were able to provide a positive impact. The community service team hopes that this community service activity can encourage behavioural changes towards better dental and oral hygiene practices.

Abstract

The Brigif retention pond not only serves to temporarily store rainwater for groundwater reserving but also reduces the risk of flooding in the Southern Jakarta area. Research was purposed to study two critical conditions of a dike made from clayey material from before to after water impounding stages correlating with its stability. The research will investigate pore-water pressure (u) parameter changes at any stage in both conditions. The parameter of (u) can be predicted (upre) using the laboratory consolidation or oedometer test and measured (uact) completely with hydrostatic pressure (u0) directly in the field. Actual measurements using a piezometer were also conducted on the body of the dike. The prediction analysis used the self-developed program and conventional geotechnical software. The critical peak depth of (u) was found at 3.0 to 4.0 m. The actual settlement potential values reached -0.10 to -1.42 m and matched the prediction result. Safety factor (SF) was around 2.0 to 4.0, or in stable condition. Research results found that the magnitude parameter of (u) could be influenced by groundwater flow and porosity or void ratio fluctuations. The consolidation process also would affect the physical soil pore, contributing to the change of (SF) the dike pond.
