Abstract

Wastewater pollution in mining areas often occurs and becomes a problem in the surrounding groundwater aquifer system. One of the efforts to determine the distribution of wastewater pollution is to calculate the discharge and volume of wastewater. In this study, an open channel in the form of a ditch or commonly referred to as a drainage system is carried out to determine the total water discharge entering the research location, design the dimensions of the sump and design the optimal cross-sectional dimensions of the ditch to overcome the discharge of water that comes out and pollutes the environment. The method used is to make an open channel in the form of a trapezoid to be used around the andesite rock mining site which then drains the mine water to the setlingpond. Efforts to drain the water that has entered the main sump (mine dewatering system) are carried out by making wells, after which the waste water is channeled into the settling pond using a pump. From the results of the study, information was obtained that the total water discharge entering the sump was 235,175 m so that the volume of the sump made was 300 m with dimensions of top area: 20m x 10m, bottom area: 10m x 10m, with a depth of 2m for total water discharge for ditches. 0.0237 m so that the volume of the trench made is 0.228 m.

Abstract

A mud volcano is one type of mountain in the world. Mud volcano has specific characteristics. In Java, several mud volcanoes spread from west to east of Java. Bledug Kuwu and Bledug Cangkring are mud volcanoes in Central Java. Research on the Bledug Kuwu and Cangkring mud volcanoes systems was not done. In this preliminary study, the gravitational field analysis of the Kuwu-Cangkring mud volcano system was done by using GGmPlus satellite data with a 220 m grid and elevation data using ERTM. Free air anomaly data processing obtained a complete Bouguer anomaly value of 23 to 34 mGal. The separation process of anomalies using the upward continuation method produces a local of -0.5 to 0.5 mGal and a regional of 23 mGal to 34 mGal. The local anomaly value of Bledug Kuwu was -0.275 to - 0.05 mGal and Bledug Cangkring-0.125 to 0.1 mGal. The local anomaly around Bledug Cangkring is higher than Bledug Kuwu, indicating a lower density beneath Bledug Kuwu than in Cangkring.
