The Gedongsongo and Nglimut areas have the potential for Indonesian geothermal exploration projects. One of the problems of the PLTP sector is producing geothermal waste in the form of brine, and geothermal mud can endanger human health and ecosystems. This study aimed to determine the best zone for waste storage ponds in this prospect area. The method integrates DEM and Landsat data analysis, producing Maps of Slopes and Lineaments to delineate the best area for making ponds. There are several parameters for determining the pond-making zone: area with a slope of less than 15%, distance from the fault is more than 200 m, and distance from areas of geothermal manifestations such as hot springs and fumaroles is more significant than 200 m. This analysis results in four delineation zones suitable for creating waste storage ponds. In the Nglimut area, there are N1 and N2; in the Gedongsongo area, there are G1 and G2 as potential zones. The best zones were N2 and G1. Locations N1 and G2 are fair zones because the eastern area of G2 is 200 m from the fault, and the northern region of N1 is close to the hot spring.

“…Lithology of Ungaran volcano and its surroundings (Figure 1) consists of Neogene sedimentary rocks (Tmk), andesite intrusion (Tma), volcaniclastic rocks (Qpkg), Old Ungaran volcanic rocks (Qpj, Qpk), and Younger Ungaran volcanic rocks (Qhg, Qls) [8,9]. The remnant of volcanic activity of Ungaran is manifested as fumaroles, altered rocks, steaming ground, and hot springs [10,11]. The unique volcanic features, beautiful volcanic landforms, and geothermal manifestations are a good opportunity to be developed as a geotourism site.…”

The indigenous nature of the Ungaran volcano-geothermal area allows us to bring the benefit to its nearest community. Geotourism can be an opportunity to introduce geological knowledge and foster the socio-cultural acceptance of society towards geothermal. This study aims to assess the potential of the study area as tourist destination. The research method is collecting data on geothermal manifestations and volcanic feature sites, quantitative assessment of geosites and geomorphosites, and preliminary hazard risk analysis. Study results identify six geosites: Gedong Songo area, Nglimut hot spring, Diwak-Derekan-Kaliulo warm spring, and Mawar camping area which features a volcanic landscape. Five of six geosites have high geotourism value of more than 0.5 in average, except for Kaliulo site. The recommendation of activities to do are leisure activities in nature, hiking, camping, thermal bathing, horseback riding, and geological excursion.Ttourists should be cautious of potential hazards risk from volcanic gases, hot and acid waters, slippery and unstable areas, landslides, rugged terrain, and extreme weather. A geotourism model is constructed to highlight each site and their attributes to Ungaran volcano-geothermal setting, tourism activities, and possible risks. By exploring the natural and geological richness offered by this destination, tourists will discover the uniqueness of volcano-geothermal tourism experience.

“…Mount Ungaran is a geothermal system stratovolcano type that has a thermal energy source in the form of Fumarole, hot soil, travertine deposits, hot springs and literate rocks that show underground geothermal activity. 1 On the north side of Mount Ungaran, namely on the slopes of the mountain in the Nglimut area, Gonoharjo Village shows geothermal reserves that appear to the surface in the form of hot springs. On the slopes of Mount Ungaran, there are also several springs, either those that appear directly or need drilling to extract groundwater.…”

The Ungaran Mountain is a stratovolcano-type volcano with a geothermal system. On the northern side of Mount Ungaran, there are hot springs located in the Gonoharjo area, Kendal Regency, Central Java, Indonesia. These hot springs appear on the mountain slopes and are very close to the surface water. This research aims in analyzing the pattern of groundwater flow with surface water flow around the springs and identifying the relationship that occurs between the springs and the nearest river flow. Analysis of the groundwater flow pattern can be determined based on groundwater level contour maps and groundwater flow maps. Such mapping can occur by plotting groundwater level data measured from 16 springs scattered on the slopes of Mount Ungaran. As a result of the measurements taken, the groundwater level ranged from 298.02 m above sea level to 818.47 m above sea level. The highest groundwater level is in the Pakis area while the lowest groundwater level is in the Boja area. The groundwater flow pattern at the study site flows from the top of the mountain and spreads to the north, northwest, west, southwest. Based on the 15 cross sections conducted, it can be identified that in general the relationship between groundwater and rivers flow in the study area is that most of the groundwater supplies surface water.
