Abstract
Dalam kegiatan tambang akan meninggalkan suatu Lubang bekas galian tambang yang pada akhirnya akan menjadi kawasan tampungan air larian dan air hujan (reservoir) Dalam upaya untuk memanfaatkan air di lubang bekas tambang penelitian ini mengevaluasi kuantitas air lubang bekas tambang batubara dengan menghitung debit menggunakan metode FJ Mock menyatakan hujan yang jatuh pada daerah tangkapan air, sebagian akan hilang akibat evapotranspirasi, sebagian akan langsung menjadi direct runoff dan sebagian lagi akan masuk ke dalam tanah atau terjadi infiltrasi. Curah hujan rata-rata bulanan di daerah penelitian dihitung berdasarkan data pengukuran curah hujan dan evapotranspirasi yang sebenarnya dari data meteorologi dengan menggunakan metode Penman dan karakteristik vegetasi. Perbedaan antara curah hujan dan evapotranspirasi mengakibatkan limpasan air hujan langsung (direct runoff), aliran dasar/air tanah dan limpasan air hujan lebat (storm runoff). Dengan metoda Model FJ Mock, dapat digunakan untuk menganalisa debit andalan lubang bekas tambang. Kata kunci: debit, lubang bekas tambang, air, pemantauan ABSTRACT Mining activities will leave an ex-mining pit which will eventually become a reservoir for runoff and rainwater (reservoir). In an effort to utilize water in ex-mining pits, this study evaluates the quantity of water in ex-coal mine pits by calculating the discharge using the FJ Mock method. states that rain that falls on water catchment areas will partly be lost due to evapotranspiration, some will immediately become direct runoff and some will enter the ground or infiltrate. The average monthly rainfall in the study area was calculated based on the actual rainfall and evapotranspiration measurement data from meteorological data using the Penman method and vegetation characteristics. The difference between rainfall and evapotranspiration results in direct runoff, baseflow/groundwater andstorm runoff. With the FJ Mock Model method, it can be used to analyze the mainstay discharge of ex-mining pits. Keywords: discharge, ex-mining pit, water, monitoring
