Abstract

In this study, the Geographic Information System (GIS) is used to assess the risk of multiple hazards in eight rural villages of Kecamatan Licin, Banyuwangi Regency, Indonesia. The study looks at six natural disasters, including floods, earthquakes, forest fires, droughts, volcanic eruptions, and landslides. It maps and classifies the level of risk using Digital Elevation Models (DEM), soil amplification factors, the Standardized Precipitation Index (SPI), and Kawasan Rawan Bencana (KRB) zonation. Weighted overlay and fuzzy logic were used to calculate the risk level of each village (low, medium, or high) with the standardized hazard factors. The results demonstrate that the risks are in very different locations. Tamansari and Kluncing villages are highly prone to multiple hazards, for instance, due to their proximity to volcanic zones, steep slopes, and floodplains. On the other hand, villages of Licin and Pakel have high risks from volcanic lahar and landslide. Villages that are close to the ground, like Banjar and Gumuk are more susceptible to flooding, while places that do not hold on to rain are more susceptible to drought. The study illustrates how risks can intersect. For example, 32% of the Tamansari area is at high risk for flooding, landslides, and volcanoes at the same time. The GIS-based framework provides useful information for selecting the best disaster prevention plans by encouraging tailored actions based on the peculiar risk profiles of each town. The results show the significance of spatial analysis to develop more disaster-resilient rural areas. This is in conformity with the Sustainable Development Goals for disaster risk reduction.

Abstract

Program implementasi reaktor biogas berbasis geomembran biodigester di Desa Wisata Kemiren, Kabupaten Banyuwangi, dilaksanakan sebagai bentuk penerapan teknologi tepat guna dalam mendukung transisi menuju energi bersih di tingkat desa. Kegiatan ini bertujuan untuk mengoptimalkan pemanfaatan limbah ternak sapi Rambon dan limbah organik rumah tangga sebagai bahan baku energi alternatif. Metode pelaksanaan menggunakan pendekatan Participatory Action Research (PAR) yang melibatkan masyarakat secara aktif dalam tahapan identifikasi, perancangan, instalasi, pelatihan, dan evaluasi. Reaktor geomembran HDPE berkapasitas 6.000 liter dirancang dengan sistem plug-flow digester dan rasio pencampuran bahan 1:1 antara kotoran sapi dan air. Hasil uji lapangan menunjukkan produksi biogas stabil sebesar 1,5–2 m³/hari dengan tekanan 0,15–0,20 bar, yang dapat memenuhi kebutuhan energi memasak dua rumah tangga per unit biodigester. Produk samping berupa bio-slurry memiliki kandungan nutrisi tinggi dan dimanfaatkan sebagai pupuk organik. Evaluasi pelatihan menunjukkan peningkatan pemahaman masyarakat hingga 80% dengan skor kepuasan 4,77 dari 5. Implementasi ini tidak hanya mengurangi pencemaran lingkungan, tetapi juga memperkuat kemandirian energi dan mendukung citra Desa Kemiren sebagai desa wisata berbasis energi terbarukan yang berkelanjutan.
MINERALOGY AND MICROSTRUCTURE OF RANTAU DEDAP'S GEOTHERMAL RESERVOIR: HYDROTHERMAL ALTERATION INSIGHTS Welayaturromadhona Welayaturromadhona; Firman Sauqi Nur Sabila; Mauliate Agustinus Hamonangan Sihotang; Luthfi Rindra Salam; Fifi Izzati

Abstract

The Great Sumatra Fault controls the Rantau Dedap geothermal system in South Sumatra. It is a high-temperature volcano-tectonic system. This study presents a comprehensive mineralogical and microstructural examination of core samples from three deep wells (UJ-A1, UJ-B1, and UJ-C1) at depths ranging from 1,840 to 2,313 m, aiming to elucidate hydrothermal alteration and its impact on reservoir quality. X-ray Diffraction (XRD) and Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDS) analyses demonstrate a distinct propylitic alteration zonation correlated with increasing depth and temperature. UJ-A1 (1840 m) is mainly made up of oligoclase, microcline, and quartz. UJ-B1 (2142 m) is mainly made up of oligoclase-quartz. UJ-C1 (2313 m) is mainly made up of anorthite-quartz with more iron. Anorthite, a calcium-rich plagioclase that stays stable above 280 °C, is found at greater depths. This means that the area is close to a major upflow zone. SEM microstructural analysis reveals hydrothermal breccia textures, characterized by angular fragments within a matrix of secondary minerals, and indicates secondary porosity resulting from mineral alteration. These characteristics suggest that hydraulic brecciation resulting from tectonic activity is essential for the creation and preservation of reservoir permeability. The reservoir's potential is enhanced because it lacks smectite-type clays, which typically block pores. In general, these results indicate that Rantau Dedap is a structurally controlled upflow zone characterized by deep mafic lithologies. The anorthite-quartz assemblage stands out as a key sign for future high-temperature geothermal exploration.

Abstract

The problem currently occurring in the Y geothermal field is a decrease in production, especially at the geothermal power plant unit 4. The solution is to drill a make-up X well, The production test using orifice meter method is one way that can be used to determine the performance of a geothermal well, which will then produce a deliverability curve. When drilling a make-up X well, of course there is a water injection process into the well, this will cause an interference effect on the surrounding wells. The results obtained from the production test using orifice meter method on make-up X well, has an electrical potential of 9.49 Mw with a steam flow rate of 70.920 kg/kWh, and the type of production fluid is superheated steam. Whereas, the wells that were interfered with by make-up X well are production wells Well-B and Well-G, for production wells that are completely uninterrupted by make-up well are Well-E, Well-K, Well-H, Well-N, and Well-O. However, there are wells that experience instrument and data manipulation problems, so that the temporary conclusion is that they are not interfered with by make-up X well, including the production wells Well-C, Well-A, WellF, Well-D, Well-J, Well-L, Well-M, and Well-I.
