Origin of Groundwater in Kawung Carang Cold Spring, Sumbang District, Banyumas Regency, Central Java

Abstract The occurrence of several springs around Slamet Volcano raised questions regarding their origin. Many studies have been conducted to understand the origin of hot spring water around Slamet Volcano. Meanwhile, there has not been any research on the origin and hydrogeological system of cold spring water around Slamet Volcano. Kawung Carang Spring is one of cold spring water that occurs on the southern flank of Slamet Volcano. It is situated in a quaternary volcanic deposit of Mt. Slamet formation. Field observation was conducted to identify local geological conditions and hydrogeological systems in the research area. Isotopic analysis was performed to help understand how to delineate the recharge area. This study used a physical-chemical analysis of Kawung Carang cold spring water and the ratio of deuterium (2H) and 18O stable isotopes to interpret its groundwater origin. The results of the analysis informed that the origin of Kawung Carang spring water was local meteoric water. The hydrogeological system was an unconfined aquifer that consisted of a lahar deposit on the top of a volcanic breccia layer. The physical-chemical characteristic of groundwater around the Kawung Carang cold spring shows low electric conductivity (EC) and total dissolved solids (TDS) values. EC and TDS values of groundwater vary from 92 to 253 µS/cm and 46 to 126 mg/L indicating that groundwater has a short time in water-rock interaction process and comes from shallow depth aquifer. Furthermore, the signature of stable isotopes of δ18O and δ2H shows the elevation of the Kawung Carang cold spring recharge area ranges from 386.08 to 441.37 meters above sea level in the northwestern part of the research area.

Pemberdayaan Masyarakat Melalui Reposisi Masyarakat Dalam Proses Perumusan Penganggaran Di Tingkat Desa (Studi Kasus di Desa Kotayasa dan Banjarsari Wetan, Kecamatan Sumbang, Kabupaten Banyumas)

So far, policy formulation almost carried out by the elite, even formally the elite has the authority while the community does not. This mechanism conceptualized in the form of formulation models, such as institutional, rational and even incremental models, and especially the elite-mass model. The position of the community directly is generally relatively weak or even almost non-existent. Initiation to involve more community roles in policy formulation has carried out as much as in deliberative and participatory models, but still, the involvement of the community becomes an object, not the subject of policy formulation. This elitist model of policy formulation, especially in Indonesia, occurs both at the national, provincial and district/city levels, the latter at the village level. By these facts, it is interesting to know the potential or prospects of the community, especially at the village level, to be the subject of policy formulation at the village level. This study uses an experimental approach with the treatment of enhancing their understanding and awareness about the formulation of budgeting policies or empowerment in legal, administrative and socio-psychological aspects. This study focuses on the process of formulating village income and expenditure budgets in two villages in Sumbang District, Banyumas Regency.
