Abstract

Jabung Village, located in Jabung District, Malang Regency, has various groundwater potentials. The study using the Vertical Electrical Sounding (VES) geoelectric method was carried out in several hamlets in Jabung Village with water shortages to map the groundwater potential in these hamlets. VES measurements were carried out in Boro Lor Hamlet, Gunung Kunci Hamlet, Umpak Hamlet, and Mindi Hamlet, with 1 reference point measured next to a drilled well belonging to the Regional Government. The results of VES analysis in 4 hamlets show that the aquifer layer is a sandstone with a resistivity of 25.8-41.7 m. The thickness of the aquifer varies from 4.6 meters to 30.1 meters. The depth of the aquifer also varies from a depth of 40.6 meters to a depth of 68.6 meters.

Abstract

Bantur District in Malang Regency is an area that is vulnerable to drought disasters. A geoelectrical resistivity survey has been conducted in Sumber Waluh Hamlet, Pringgodani Village, Bantur District, Malang Regency as an effort to mitigate drought disasters. This study aims to identify the distribution of aquifer layers based on the results of subsurface resistivity modeling. The identified aquifer layers can be used as a solution to the problem of drought disasters. In this study, geoelectrical resistivity measurements used the VES technique, i.e. the Schlumberger configuration, which was carried out at seven points. Analysis of the modeling results showed the existence of a shallow aquifer layer with a depth of 8-20 meters and a deep aquifer with a depth range of 50-70 meters. The aquifer layer has a resistivity value between 0.51-31.36 Ωm which is interpreted as a tuffaceous sandstone layer. In hydrogeological modeling, it is interpreted that the position of the groundwater level is at a depth of 40-50 meters. Thus, the results of this study can be used as a recommendation for drilling points to find new water sources in the research area.

Abstract

Lokasi SMA Negeri 1 Tumpang di Desa Malangsuko, Kabupaten Malang berpotensi terjadi bencana alam, seperti halnya beberapa wilayah lain di Kabupaten Malang, salah satunya adalah gempa bumi. Namun demikian, pendidikan mitigasi bencana yang melibatkan aktivitas partisipatif dari siswa-siswi di sekolah tersebut belum pernah dilakukan. Kegiatan school watching dilaksanakan sebagai upaya meningkatkan kesadaran terhadap potensi bahaya di lingkungan sekitar bagi siswa-siswi di SMA Negeri 1 Tumpang. School watching merupakan kegiatan pemetaan potensi bahaya yang ada di sekitar sekolah. Hasil pemetaan tersebut selanjutnya disajikan dalam bentuk peta dan dipresentasikan oleh peserta. Sebanyak 50 siswa-siswi SMA Negeri 1 Tumpang dilibatkan dalam kegiatan ini yang dibagi menjadi 5 kelompok. Masing-masing kelompok didampingi oleh satu orang dari tim Pengabdian kepada Masyarakat (PkM). Kegiatan ini berhasil meningkatkan kepekaan peserta terhadap potensi bahaya yang ada di sekitarnya. Hal ini terlihat dari presentasi potensi bahaya yang ada di sekolah dan upaya mitigasinya. Lebih lanjut, hasil pengisian kuisioner menunjukkan lebih dari 90% peserta menyatakan kegiatan tersebut penting untuk meningkatkan kepekaan terhadap potensi bahaya di sekitarnya. Oleh karenanya, kegiatan school watching perlu dilakukan secara rutin dengan melibatkan semua siswa-siswi dan guru di SMA Negeri 1 Tumpang dan sekolah-sekolah lain sebagai upaya menciptakan warga sekolah yang tanggap bencana.

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

Purwodadi Village, located in East Java, Indonesia, has recently gained recognition as one of the top tourism villages in the country. With its rich geological heritage and unique landforms, the area holds significant potential for geotourism development. This study explores sustainable geotrail planning by characterizing geodiversity across nine identified geosites and assessing their vulnerability to degradation. Field surveys and geosite inventories were conducted following the Geological Agency’s technical standards, supported by a 4A analysis framework consisting of attraction, accessibility, amenities, and ancillary services. Additionally, a weighted overlay method incorporating slope, rainfall, soil type, and land cover data was used to map degradation risk. The findings reveal that each geosite possesses moderate to high geological significance, with varying degrees of susceptibility to erosion and anthropogenic impact. The proposed geotrails are thematically organized to reflect the area's ancient volcanic history, offering both educational and recreational value. The results contribute to sustainable tourism planning and geoheritage conservation efforts by identifying strategies to manage geosites while preserving their scientific and aesthetic value for future generations.

Abstract

Volcanic eruption is one of the phenomena that can change the volcanic landscape drastically. Monitoring of volcanic edifices after eruptions should be considered to further understand the potential hazards in the future. Satellite monitoring is a reliable technique for assessing deformation in a volcano. InSAR was applied to detect material build-up after the eruption phase of Semeru Volcano in December 2022. As a consequence of the opening crater along with the InSAR result, a lahar product after the eruption was deposited in the southwest direction. Significant deformations were indicated by PS-InSAR near the crater, which was characterized by a LOS displacement of -10 to -40 mm/year, indicating scouring of the pyroclastic material moving down the slope. The accumulation of pyroclastic flows from the abrading process below was detected in the proximal zone of Semeru, as shown by the positive LOS displacement ranging from 10 to 40 mm/year. The field survey conforms to the PS InSAR results, where unconsolidated material, ranging in size from gravel to boulders, piles up approximately 4-5 m in Curah Kobokan. Highly unconsolidated material tends to move easily by water and threaten the surrounding settlements. Overlying PS InSAR and drainage pattern in the flank of Semeru, concluding several locations that have a high-risk potential of being affected by lahar flows are Curah Kobokan, Supiturang Village, Pronojiwo District, then Tulungrejo, Pasropan Village, Pasrujambe District, Lumajang Regency.

Abstract

Background: Farmers can market their crops due to the significant market share for hydroponic agriculture products. However, this presents a dilemma as the market demands a consistent supply of high-quality crops. Precise nutrient levels and controlled chemical-physics parameters are crucial considerations in hydroponic yields. Thus far, these factors have been managed manually, leading to challenges in achieving desired outcomes. Objective: This community service program aimed to address this issue by developing a real-time automated system for monitoring and controlling chemicalphysics parameters and nutrient levels via an Android application. The goal was to enhance the effectiveness and productivity of hydroponic crop harvests. Method: The program commenced with designing the system based on farmer requirements, followed by the installation and testing of equipment at partner locations. Subsequently, technical training on system features and usage was provided. Results: The system was successfully installed at Grahaponik. According to questionnaire responses, 68.4% of farmers expressed satisfaction, and 78.9% of total participants reported that the system was easy to employ. Technology installation, implementation, and dissemination to local hydroponic farmer groups were conducted. Hydroponic farmers acknowledged the user-friendliness of the devices. Conclusion: Partners' acceptance of the instruments was favorable, facilitating their ease of use and thereby enhancing the effectiveness of hydroponic farming.
