Abstract

Based on trace geological history and several studies, the Sangiran mud volcano provides insight into the geology and hydrology of the region, aquifer system in the basin, groundwater flow patterns and characteristics, rock lithology, hydrogeology condition, and saltwater trap mapping. Related to these conditions, studies were conducted on the magnetic content and composition of the major oxide compounds in the Sangiran sediments. Sample analysis was based on geochemical methods. The methods consist of frequency dependent magnetic susceptibility and vibrating sample magnetometer (VSM) analysis. Geochemical analyses using x-ray fluorescence (XRF) analysis have been conducted and various elemental grades have been determined. VSM results confirm that the magnetic content of Sangiran sediments is partly dominated by Fe (17.66 percent) contained in hematite (Fe2O3). At the same time, the samples of Sangiran sediment were enriched by Si, Fe, Al, Ca, Cl, Ti, and K according to XRF measurements. The samples exhibited the highest Si and Fe concentrations in samples T1 (Si is 29.48 percent and Fe is 13.66 percent) and T7 (Si is 24.95 percent and Fe is 12.01 percent). Meanwhile, in the T4 sample, the highest concentrations were Si and Ca, 23.45 percent and 13.45 percent, respectively. Retrieved from the magnetic susceptibility measurement, this paper confirm that Fe content is one of the components of volcanic ash in the Sangiran sediment.DOI: 10.17977/um024v8i12023p009

Abstract

West Kalimantan is a province in Indonesia that has 1.73 hectares of peatland. In utilizing peat soil, it is necessary to know several indicators, such as electrical conductivity and soil texture, to see whether or not it is suitable for plantation land. This study examines the relationship between electrical conductivity and soil texture supported by the K-Means Cluster statistical method on peat melon plantations in The village of Rasau Jaya, West Kalimantan. Electrical conductivity measurements were carried out using a conductivity meter, soil texture classes were determined using the USDA (United States Department of Agriculture) classification method, and clustering was used the K-Means Cluster statistical method. Besides that, the physical characteristics of the soil were observed visually using the Munsell Soil Color Chartbook. The research showed that melon plantation soil has two layers with straight-line delineation. The first layer has a range of electrical conductivity values of 0.14 dS/m, has a clay texture, and has a color code of 10 YR 2/1. The second layer has a range of electrical conductivity values of 0.07 dS/m, has a sandy loam texture, and has a color code of 10 YR 2/1

Abstract

Indonesia is a country with a high frequency of natural disasters due to its location in the tropics and along the pacific ring of fire. Its diverse topography, characterized by numerous mountains and coastal areas, significantly influences land slopes. One common disaster associated with slope differences is landslides-mass movements of soil triggered by various factors, one of which is the steepness of the slope. Cianjur Regency is among the regions with a high risk of landslides. According to data from the West Java Regional Disaster Management Agency (BNPB), Cianjur experiences more than 90 landslides annually. Therefore, mitigation efforts must be carried out based on landslide risk mapping in this region. The purpose of this research is to identify and map landslide-prone areas in Cianjur Regency. Mapping results from 2018 to 2023 indicate that areas with the highest landslide risk are concentrated in northern Cianjur, particularly in the districts of Cugenang, Cipanas, Sukaresmi, and surrounding areas. Mitigation efforts should be prioritized in these districts without neglecting other areas. In addition to the 2018–2023 mapping, a 2025 prediction map can also be developed to guide broader and more comprehensive mitigation efforts, which still indicate a very high risk in northern Cianjur. Furthermore, mapping using the SMORPH method has produced results that closely align with both the annual and predictive mapping approaches, reinforcing the validity of the identified high-risk zones.

Abstract

The development of satellite data has played an important role in monitoring natural disasters on the Earth's surface. Providing an overview of the current conditions of a volcanic crisis, including information on lava flow extension, is a challenge in observing volcanoes. Various methods were used to map lava flows, such as identifying lava on optical satellite images and detecting thermal anomalies emitted by hot lava. This study aimed to generate a preliminary map of active lava flow caused by the 2022 Mauna Loa eruption in near real-time by analyzing fire radiative power (FRP) data acquired from Suomi National Polar-orbiting Partnership (S-NPP) and National Oceanic and Atmospheric Administration-20 (NOAA-20) satellites. FRP data was filtered to identify lava flow using statistically determined thresholds from its value distribution, including the 5th percentile, 3rd quartile, mean, and 95th percentile. The obtained active lava flow map is evaluated using confusion matrix analysis by comparing the estimated map with the reference map. The maps generated using various thresholds were compared, and the best result was provided by the threshold of the 3rd quartile, with S-NPP and NOAA-20 FRP threshold values of 27.2 and 27.9 MW/pixel, respectively, with overall accuracy reaching 97%. The higher threshold reduced the overestimated lava location represented by a false positive (FP) value. The results show that the active lava originated from the summit caldera, and the eruptive fissure on the northeast flank extended to the northeastern area with an estimated daily distance reaching about 18 km from a certain reference point. This preliminary lava flow map can provide general information regarding areas prone to lava flows, especially around Mauna Loa, and support related parties in updating hazard zones rapidly. The findings should help make immediate decisions for evacuation routes and public warnings when an eruption occurs without visiting the volcanic area directly.
