Analisis Nilai Transmisivitas Dan Storativitas Air Tanah Gambut Berdasarkan Uji Pemompaan (Pumping Test)

---

The exploitation excessive peat fires resulted in the dry season. This fire can be minimized by utilizing the potential of groundwater on peatlands. The potential of groundwater can be determined by pumpingtestso that it can be known the aquifer characteristics in the form of storage capacity (storativity), transmisivity coefficient, and decrease in groundwater level in the observation well. Pumping tests are carried out in two stages, the first stage is pumping test at the production well to observe the groundwater level drop that occurs due to pumping process and the second stage ofrecovery testwhich is carried out to observe theprocess recharge from the pumping observation wells. Groundwater level reduction can be determined using two methods, namely Cooper-Jacob Method and Sunjoto Method. The decrease in groundwater level with Cooper-Jacob in the 45th minute is 0.314 m and the Sunjoto Method is 0.596 m. Difference in groundwater level analyzed by RMSE, for Cooper-Jacob Method obtained value of 0.1134 and Sunjoto Method obtained at 0.17948, so the Cooper-Jacob Method is used as a basis for finding transmissivity and storativity. The transmissivity value of the pumping test obtained was 491,786 m2/day, the transmissivity of the relapse test (recovery test) was 203,356 m2/day, and storativity was obtained at 4,23 10-3.Based on these two parameters, the potential availability of ground water is obtained by themethod trial and error of 1066.17 m3/day.
