Analysis of spring discharge quantity in a fractured karst aquifer of the Klapanunggal Formation, Ligarmukti Village, Bogor Regency, West Java

Abstract

Indonesia has karst areas spread across Sumatra, Java, Sulawesi, Nusa Tenggara, Maluku, and West Irian. On Java Island, there is one of the main karst areas, namely the Klapanunggal Formation in Ligarmukti Village which is our research area. Karst areas are able to store and drain water (aquifer zones) due to the dissolution process in carbonate rocks that have the potential to be a source of spring water. There are several karst media aquifer springs in the study area, one of which is Sodong Spring which drains water through fracture media. The existence of Sodong Springs can meet the raw needs of the surrounding community and become a source of income from the tourism sector. In connection with this, this study was conducted to test the quantity of discharge in Sodong Spring which can always meet the needs of the community until now even in dry conditions. The conduct of this research aims to develop the use of Sodong Springs which supports the lives of the surrounding community. In this case, the community will more effectively utilize the source of Sodong Spring. The method to be carried out in this study is a quantitative method based on hydrogeological observations. Sodong spring water will be able to be developed for utilization because of the very high discharge. The results of this research will later become an indicator of the development of water use in the Ligarmukti Village area that can be used sustainably.
