Abstract

Andesite rock identification has been carried out in Satui, South Kalimantan using the geoelectric method. Four lines resistivity measurement using Wenner configuration are used with a length of 200-350 m. The purpose of this study is to determine the depth, thickness and position of andesite rocks in the measurement area. Based on the results of processing there are three types of layers in the measurement area, clay with a resistivity of 9.760-68.373 Ωm, sandstones with a resistivity value of 68.373-324.509 Ωm and andesite with a resistivity ≥ 324.509 Ωm. The results of 2D interpretation show that the andesite rock in the entire first path are at a distance of 10.00-170.00 m, depth 6.76-9.94 m and thickness 7.36-10.54 m. Andesite in the second lane are found at a distance of 80-345 m, depth 1.25-9.94 m and thickness 2.62-10.54 m, on the third lane found at a distance of 100.00-200.00 m, depth 13.40 m and 3.90 m thick. Andesite in the fourth lane are found at a distance of 5.00-175.00 m with a depth of 6.76-13.40 m and thickness 1.95-10.54 m.

Abstract

Peatland fires have been a long-standing topic of discussion in combating greenhouse gas effects, especially in Indonesia, which has the largest tropical peatlands in the world. However, peatland fires have their own complexities, one of which is that hotspots do not always reflect the amount of carbon emissions. This study was conducted in the Kahayan-Sebangau Peatland Hydrological Unitary (KHG) by integrating several spatial data sets: MODIS hotspot distribution data from 2019 to 2022, peat thickness data, forest area status data, land cover data from 2018 and 2022 with carbon content values based on the 2015 national guidelines of the Ministry of Environment and Forestry (KLHK). Carbon emissions were estimated from changes in land cover and carbon reserves per hectare. The results show that Production Forests (HP) contribute >40% of total hotspots and >80% of carbon emissions, while Conversion Production Forests (HPK) have the highest hotspot density at 1.08 hotspots/km2 and the highest carbon emissions are found in the deep peat thickness class. This study found that the status of forest areas and peat thickness greatly determine the amount of carbon emissions from a fire, as indicated by the distribution of hotspots.
Pemantauan Dinamika Land Surface Temperature dan Indeks Spektral (NDVI) Menggunakan Landsat ETM+ dan OLI/TIRS di Lanskap Jember Selatan: Monitoring Land Surface Temperature and Spectral Indices (NDVI) Dynamics Using Landsat ETM+ and OLI/TIRS in the Southern Jember Landscape Sholihah, Rizqi I'anatus; Putra, Rizki Auliansyah; Santosa, Lenalda Febriany; Atmadja, Krisologus Genesa Ruby; Wulandari, Verlina Intan; Rahman, Basuki; Islami, Muflihatul Maghfiroh; Kusneti, Monica

Abstract

Landscape transformation driven by rapid urbanization is a primary determinant of microclimate change in peri-urban regions. This study aims to analyze the spatiotemporal dynamics of land surface temperature (LST) and its relationship with vegetation density (Normalized Difference Vegetation Index/NDVI) in the Southern Jember landscape. Utilizing Landsat 7 ETM+ and Landsat 8 OLI/TIRS imagery from 2001, 2013, and 2025, this research evaluates the impact of land cover changes on the regional thermal regime and vegetation index variability. The results reveal a fundamental landscape transition, where the dominance of paddy fields shrank drastically from 66.400 ha (2001) to 13.800 ha (2025), replaced by a massive expansion of settlements reaching 82,900 ha. This shift triggered a significant surface urban heat island (SUHI) phenomenon. Settlement areas recorded an extreme maximum LST of 38,1°C in 2025, a sharp increase compared to the initial study period. Spectral analysis confirms that the rise in LST has a negative correlation with NDVI. This evidence suggests that the loss of vegetation biomass and the increase in impervious surfaces due to uncontrolled urbanization are the primary drivers of environmental warming in South Jember. These findings underscore the urgency of climate-mitigation-based spatial planning strategies for regional sustainability.

Abstract

Pengamatan menunjukkan pola persebaran yang tidak merata, dengan keberadaan spesies sangat ditentukan oleh karakteristik habitat dan ketersediaan sumber pakan. Spesies sensitif seperti Rangkong badak (Buceros rhinoceros) dan Cica-daun besar (Chloropsis sonnerati) hanya dijumpai di hutan primer yang menyediakan pohon tinggi dan minim aktivitas manusia. Sebaliknya, Elang-ular bido (Spilornis cheela) tercatat di habitat hutan primer dan sekunder yang masih mendukung ketersediaan mangsa. Beberapa spesies seperti Kipasan belang (Rhipidura javanica) dan Sepah raja (Aethopyga siparaja) menunjukkan toleransi yang lebih baik terhadap aktivitas manusia selama habitat masih menyediakan kebutuhan spesifik mereka. Penelitian ini menyimpulkan bahwa strategi konservasi perlu mempertimbangkan karakteristik spesifik setiap spesies, dengan kombinasi perlindungan habitat kunci dan pengelolaan terhadap habitat dengan aktivitas manusia yang tinggi. Penelitian ini bertujuan untuk menganalisis faktor-faktor penentu persebaran burung langka tersebut guna menjadi bahan kajian terhadap kepentingan konservasi.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk memperkuat literasi lingkungan anak-anak di Panti Asuhan Sentosa Banjarmasin melalui edukasi bijak energi dan pengelolaan sampah. Kegiatan dilaksanakan pada 29 November 2025 dan melibatkan 15 peserta dengan jenjang pendidikan sekolah dasar. Metode kegiatan meliputi ceramah interaktif, demonstrasi partisipatif, diskusi, penggunaan media visual, simulasi pemilahan sampah, permainan edukatif, dan kuis hemat energi. Pelaksanaan terdiri atas tahap persiapan dan koordinasi, penyampaian dua materi utama, serta evaluasi sederhana melalui observasi partisipasi dan respons peserta selama kuis dan simulasi. Hasil kegiatan menunjukkan partisipasi aktif peserta dari awal hingga akhir. Pada evaluasi akhir, peserta mampu mengidentifikasi perilaku boros energi, menyebutkan praktik penghematan energi, serta membedakan sampah berdasarkan kategori organik, anorganik, dan B3. Secara praktis, program ini mengintegrasikan dua dominan tindakan lingkungan sehari-hari, yaitu hemat energi dan pengelolaan sampah, dalam satu intervensi partisipatif yang dikontekstualisasikan dengan nilai tanggung jawab di lingkungan panti asuhan. Kegiatan ini dapat menjadi dasar awal bagi pembiasaan ramah lingkungan, tetapi belum mengukur perubahan pengetahuan dan perilaku secara kuantitatif maupun jangka panjang. Keberlanjutan program perlu diperkuat melalui pendampingan berkala, penyediaan sarana pemilahan sampah, pembentukan duta lingkungan, dan kemitraan dengan bank sampah.
