Abstract

Mount Semeru is an active volcano located on the island of Java. On December 4, 2021, Mount Semeru erupted again, resulting in damage and loss of life. Sentinel-2 satellite imagery was utilized for mapping vegetation areas, while Sentinel-3 was employed for assessing surface temperatures. The NDVI distribution related to the Semeru volcano eruption indicates that the extent of cloud cover, water, and open vegetation was consistent before, during, and after the eruption. Before the eruption, areas of very low vegetation were more prevalent than during and after. In contrast, areas of low vegetation were more common following the eruption compared to the eruption period and before it. Medium vegetation remained dominant after the eruption in comparison to the periods before and during it. In contrast, high vegetation was most abundant during the eruption and was at its lowest before the eruption occurred. The land surface temperature recorded before the eruption ranged from a minimum of 11.8 °C to a maximum of 30.12 °C. During the eruption, temperatures peaked at 42.4 °C and dropped to a low of 14.0 °C. Following the eruption, the maximum temperature recorded was 40.8 °C, with a minimum of 11.6 °C. The presence of lava flow during and after the eruption is indicated by the red circle on the land surface temperature map, and when compared to the NDVI map, the black circle shows areas where vegetation was absent due to the lava flow observed on the land surface temperature map

Abstract

Indonesia is situated amidst three major tectonic plates: the Indo-Australian Plate, Eurasian Plate, and Pacific Plate. As a consequence, the country is characterized by numerous volcanoes, frequent earthquakes in various regions, and the occurrence of tsunamis. Particularly in the southern region of Java Island, this coastal area is a disaster-prone area. One of the areas is Tambakrejo Village, which is located in the coastal area of Malang Regency, which has potential in the form of beautiful beaches, abundant fishery products and development of the tourist village. This research aims to create a tsunami evacuation route map using a GIS. The digital elevation model data was obtained from Geospatial Information Agency using reclassification based on variations in altitude levels. Distance data from the coastline is processed using a base map of the research location and assisted by the Multiple Ring Buffer Toolbox. Land use data is processed using the Maximum Likelihood Classification process, the data used is Landsat 8 imagery. Determination of tsunami evacuation routes is carried out by implementing the Network Analyst method. The Network Analyst method uses the starting point of the incident to the end point of the facility to produce an appropriate evacuation route. The results show four new gathering points and 6 recommended evacuation routes for Sendangbiru, Tamban and Sendiki Beaches respectively.

Abstract

To date, performance of the management of Indonesian production forests are discouraging. The concession areas, timber production and employment have been decreasing over time. concern on these matter and to improve management, a research was conducted for six years (2008-2013) and resulted in recommendations to implement the Multi-System of Silviculture (MSS) systems. Two products were generated in MSS; criteria and indicator to guide the selection of appropriate silvicultural system and supersilvik, a model to develop the best business plans. This paper evaluates and strengthens the recommendations through the simulation of MSS products in PT. Sarmiento Parakantja Timber (Sarpatim), Central Kalimantan, Indonesia. Various data variables were used, such as thematic maps of forest areas, data of stand, materials, equipments, labors, finances and incomes. Data were processed in a variety of formulations which were connected to each other in model systems to produce a variety of outcomes, such as production, finance, employment and tax contributions. Results offer four options to improve PT. Sarpatim performance, one of which is the best choice. Compared to the former business model under limited silvicultural systems, MSS projected an increase in the use of land, timber production and employment by 151-753%. Implementing MSS will provide a better and healthier finance for company with an increase of NPV up to 193%; as well as for government tax revenues with an increase up to 308%.

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.

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.
