Abstract

Being in an active fire lane means that Indonesia has geothermal potential. The geothermal research location is in the Tempuran area, Magelang Regency. The method used is by using alignment in the National Digital Elevation Model (DEMNas) data and calculating it using the Fault Fracture Density (FFD) method, the result of which is a contour map. This research aims to identify the existence of geothermal manifestations with FFD values. The research results show that the FFD value in the Tempuran geothermal manifestation area varies between 0.09 - 1.80 km/km2. The FFD value shows that the Tempuran geothermal manifestation is in a low density zone. There is no direct correlation between the presence of geothermal manifestations and the FFD value. The Tempuran geothermal manifestation is thought to be related to geological formations composed of volcanic rock and related to an aquifer system, as well as faults that trend northwest-southeast.

Abstract

On July 7, 2024, an M4.4 earthquake affected Batang, Warungasem, and Wonotunggal sub-districts, causing minor to major damage to houses. This study intends to conduct macroseismic and microseismic studies in the earthquake-affected zone. Macroseismic analysis involves determining the amount of building damage on the MMI intensity scale, whereas microseismic analysis relies on dominant frequency characteristics (fo), amplification factor (Ao), and local geology. Macroseismic study indicates that the Batang earthquake had an intensity of III-IV MMI. The amount of light-to-heavy building damage does not affect the earthquake intensity (MMI) number. This is because the destroyed structures were constructed in a simplistic manner and were not earthquake-resistant. Microseismic investigation revealed that the Alluvium Plain had the dominating distribution of damage, with fo values <3.4 Hz and Ao >4.8. Aside from building quality, local geological variables have an impact on earthquakes on the surface.

Abstract

Located on the Pacific Ring of Fire, Indonesia has great potential in significant geothermal energy. Kamojang, located in Samarang District, is one of the areas that show this potential. This study aims to assess the existence of geothermal potential in Kamojang through fault density analysis using the Fault Fracture Density (FFD) method. The data used are fault patterns from the National Digital Elevation Model (DEMNas) which are then analyzed to calculate the density of cracks and presented in the form of contour maps. The resulting FFD values range from -0.5 to 9.5 km/km². The results show that the alignment pattern in Kamojang is mostly northwest - southeast, which is closely related to tectonic movements and the formation of active faults in the area. Although the FFD value in this area is relatively low, the presence of active faults still provides a pathway for the movement of geothermal fluids that form geothermal manifestations such as geothermal craters. These results provide important insights to support the management and development of geothermal energy in the Kamojang area.

Abstract

Ngawi is one of the areas in East Java province with an area that has topographic variations in the form of lowlands and highlands, because of its location on the slopes of Mount Lawu. There are several areas in Ngawi Regency that have the potential to be prone to landslides, which were then identified as suitable between the landslide hazard map which was derived from combining rainfall parameters, slope slope and geological conditions. Next, the landslide hazard map was compared with the FFD map produced from DEM (Digital Elevation Model) alignment analysis. The resulting landslide map is in accordance with the FFD map produced, namely in Sine sub-district, Ngrambe sub-district, Jogorogo sub-district and Kendal sub-district.
