Analysis of groundwater sufficienty for domestic and livestock requirements as an anticipation to sea water intrusion in Kebumen coast

This study has three objectives, i.e calculating the availability of groundwater in area, water demand for domestic and livestock evaluating safe yield extraction. To achieve these availability, actual utilization are calculated. Groundwater is calculated based on multiplication aquifer thickness specific yield. Water determined base number population amount each person day. consumption day, while annual level fluctuation The results research showed that area reached 440,517,770 m 3 /year, its extraction was 76,641,600 /year. Because 6,495,100 so still sufficient to support sectors. two sectors have not exceeded extraction, it will cause decreasing pressure which can sea intrusion.
