The Community Service (PKM) team from the Graduate School, the Environmental Science Master Program, interest Environmental Management Master Program, has conducted a field survey with the theme “Investigation of Aquifers and Groundwater Potential for Clean Water Provision in Mojosari Hamlet, Kedung Poh Village, Nglipar District, Gunungkidul Regency.” This activity was carried out as a manifestation of SPs’ concern for vulnerable communities. The activity began on August 14th 2024.
According to Dr. Tjahyo Nugroho Adji, MSc.Tech., the Chief of the Community Service Team, the location was chosen because, geologically, the area is water-scarce due to the inclusion of the Sambipitu Formation at the top (sandstone and mudstone) and the Nglanggeran Formation below (volcanic breccia, agglomerate, andesite basalt lava, and tuff). As a result, water only occupies gaps or fractures in the volcanic rock. In addition, several drilling attempts by the community have failed due to a lack of scientific research support.
“Based on this, community assistance is necessary. Therefore, precise detection is required to determine where groundwater is stored and can be extracted in sufficient quantities, using a water detector tool that employs very high to very low-frequency electromagnetic waves to detect this groundwater potential,” continued Mr. Adji (the Head of the Team).
The Community Service team consists of Dr. Langgeng Wahyu Santosa, MSi, and Ir. Erik Febriarta, MSc. From the two surveyed locations, the team found layering within the gaps of the rock at a depth of around 120-150 meters below the surface, with an estimated flow rate of 0.85-1.25 liters per second. The team hopes that the results of this study can be quickly realized in the form of well drilling so that the community’s clean water needs can be provided properly.
