Abstract

PT MAS operates in the mining sector, extracting white rocks or feldspar from steep and rugged slopes. Inadequate drainage systems pose significant challenges, such as floods, erosion, and landslides, emphasizing the critical role of effective drainage in mining activities. The designed drainage system incorporates trapezoidal open channels at the mining steps' base. Before reaching natural water bodies, mining water is directed to sedimentation ponds to settle sediments. This research, an experimental study correlating theory with field data, begins with a literature review on open channel drainage theories in mining areas. Data collection includes location specifics, mining area dimensions, rainfall, and runoff coefficients. Manning equation calculations determine planned open channel dimensions, with a bottom width of 0.45 m, flow depth of 0.39 m, freeboard height of 0.097 m, water surface width of 0.9 m, and a slope angle of 60⁰. The research aims to contribute insights for the development and management of open channel drainage systems in mining areas.

Abstract

The aim of limestone mining activities is to obtain the main raw material, namely limestone, which can then be used as a construction raw material such as cement. This data collection method is to collect primary data obtained from identifying activity locations and secondary data obtained from Journal Reviews and other scientific articles and then compiling them into a narrative. From the results of this analysis, it can be seen that there is a positive impact, namely the recruitment of workers from the local area and a negative impact, namely a decrease in ambient air quality, a decrease in water quality, soil erosion, disruption of flora and fauna and plant vegetation.

Abstract

Land cover is defined as the physical and biological cover of the earth's surface, both those formed naturally such as swamps, hills and rivers and those formed by man-made means such as rice fields, gardens, forests and buildings. As technology develops, conventional methods of satellite image processing are starting to be abandoned. This is because conventional methods require quite a long time to process satellite image data. The presence of Google Earth Engine (GEE), which is a cloud computing-based platform, makes it easier for users to process satellite image data boldly and for free. This research aims to classify satellite image land cover in the Trenggalek Regency area, East Java. The level of accuracy in this study uses a confusion matrix. The accuracy test results show a value of 90.23%.
