  Working as Consultant Hydrogeologist in Consultant Company, have some responsibilty to handle Hydrogeological Project on Coal Mining PT. Marunda Graha Mineral. Goals of this project is develop hydrogeological monitoring well, create groundwater conceptual and numerical model in PT. Marunda Graha Mineral Mining area, estimate groundwater volume in active mining area for dewatering estimation, and update feasibility study documen for PT. Marunda Graha Mineral. ❖ Coordinate with owner (PT. Marunda Graha Mineral), Drilling contractor (PT. Duta Borneo Mining) and wellsite geologist to implement hydrogeological drilling program. ❖ Geological, hydrogeological and hydrological mapping to know actual condition on site mining area and collect data from field for groundwater model. ❖ Supervise hydrogeological drilling program and supervise groundwater monitoring well construction. ❖ Carry out the in-situ test (Pumping test and slug test) on hydrogeology monitoring well to know the value of permeability on the aquifer, and calculate optimum and maximum discharge from the aquifer. ❖ Take groundwater samples to analyze chemical and biological content. ❖ Create geological and hydrogeological conceptual models. ❖ Create a hydrogeological numerical model to determine the condition of groundwater in actual conditions during mining activity. ❖ Calculate Potencially Acid Forming (PAF) and Non Acid Forming (NAF) from rock sample and classify the distribution of rock that contain PAF and NAF ❖ Make a report for PT. Marunda Graha Mineral related on Hydrogeology and Hydrological condition on their mining area and give recommendation for dewatering program based on the result of hydrogeological and hydrological actual condition.

  I was working as a freelance Hydrogeologist, working on my lecture project. I was doing geology and hydrogeology mapping, geophysics data acquisition in Tangerang Groundwater Basin, make geological data analysis and reconstruction. Analysis geophysics subsurface data to know the existence of aquifer, take and analysis data from pumping test, and analysis groundwater geochemistry data to know the type and groundwater characteristic then compared with Government National Standard for drinking water. Make a final report to suggest the company for estimation groundwater production/abstraction, groundwater treatment with the goals to maintain groundwater sustainability around production area.
