Abstract

One of the solutions for water shortage in Grobogan District is groundwater utilization. Excessive groundwater pumping will decrease groundwater level and trigger a landsubsidence. It is necessary to conduct hydrogeological study to determine the groundwater storage in this area. The purpose of this research were to determine the hydrogeological conditions, aquifer characteristics and potential of groundwater storage in Grobogan district. This research used geoelectrical method to identify rock characteristics. The results showed that the geological formation in Grobogan district consisted of Qa, Tmpk, Tmpl, Tps, Tmw and Qp. Grobogan district had 5 aquifers system, there are: poorly productive aquifers, moderately productive aquifers, locally productive aquifers, extensive productive aquifers and region without exploitable groundwater. The aquifer layer consisted of sand, marl sandy, silty sand and calcareous sand. The unconfined aquifer was located at 1,2 - 58 m from soil surface with average thickness of 13,54 m and the hydraulic conductivity of 3,54 m/day. The confined aquifer depth can be estimated between 29 - 174 m from soil surface with average thickness of 37,4 m and the hydraulic conductivity of 3,87 m/day.The predicted groundwater storage in Grobogan district of unconfined aquifer was 401,33 l/sec and confined aquifer was 1.804,95 l/sec.

Abstract

The water supply at the IPB Education and Research Garden Jonggolis generally sourced from rainfall. This can lead to water shortage during certain periods, so building a water storage structure such as a small reservoir (embung) is necessary. The embung can provide a more stable water supply by storing rainwater and river inflow. This research aims to design an embung at the IPB Education and Research Garden Jonggol, and to analyze the water balance of the planned embung. This study presents the application of SWAT-based dependable discharge analysis for small-scale industrial reservoirs in tropical regions. The findings support sustainable water management and enhance enhance agro-industrial resilience, particularly in regions dependent on rainfall. The planned embung is designed for the palm oil processing plant with a total water requirement of 8,786 m3 in the dry season. Dependable discharge analysis is conducted using Soil Water Assessment Tool (SWAT), while flood discharge analysis uses the rational method. Embung capacity design is based on water availability, water requirement, sediment volume, and total evaporation. The planned embung will be located at coordinates 107° 2' 10.53" E and 6° 28' 17.60" S. It features a normal water surface area of 7,737.19 m², a normal water depth of 3 m, and a total storage volume of 9,947.76 m³. The design includes essential components such as an overflow channel, an outlet channel, and an embankment. The water balance indicates that the embung will begin filling in February and remain full from March to May. Subsequently, the water balance is expected to repeat its cycle consistently, ensuring that the embung can meet the water demand at the location.
