Abstract

The mining industry in Indonesia plays an important role as the source of state income and the part of industrial progress of a nation. The majority of mining industry in Indonesia is an open pit., including clay mine that mined by United Tractors Semen Gresik Ltd in Temandang Village, Tuban. An open pit is a mining method that is directly exposed to the free air because it is above the earth’s surface. Therefore, weather factor greatly affects the productivity of the open pit apart from the factors of work effectiveness and material hardness. The result of the study showed that Temandang area has rainfall 135 mm/month. The average of the small production was 76.000 tons per month, so it becomes the researcher’s attention to analyze how great the rainfall influenced the production decrease. To achieve the production capacity target, an analysis by using linear regression equation, in which equation formula of the best statistical test result is as follow : Log P = 0,5025 x [ log {(Pr x JK)1,99 x (CH)-0,001}] + 0,0013. The calculation result by the mathematical model equation above showed that the effect of rainfall on production decrease was very small. Thus, the working hour and productivity greatly affected the production. So, if the production needs to be increased, then the working hour must be increased

Abstract

Usaha Pertambangan adalah sebagian atau seluruh tahapan kegiatan dalam rangka penelitian, pengelolaan dan pengusahaan mineral dan batubara yang meliputi penyelidikan umum, eksplorasi, studi kelayakan, konstruksi, penambangan pengolahan dan pemurnian, pengangkutan dan penjualan serta kegiatan pasca tambang (Pasal 1 butir 6 Undang-Undang No.4 tahun 2009 tentang Pertambangan Mineral dan Batubara). Pertambangan mempunyai beberapa karakteristik , yaitu tidak dapat diperbaharui (non renewable), mempunyai resiko relatif lebih tinggi dan pengusahaannya mempunyai dampak lingkungan baik fisik maupun lingkungan yang relatif lebih tinggi dibandingkan pengusahaan komoditi lain pada umumnya. Pentingnya penerapankegiatan industri dan/atau pembangunan yang berbasis lingkungan, perlu disadari oleh setiap elemen bangsa, karena persoalan lingkungan merupakan permasalahan bersama. Hanya saja dalam pratiknya, diperlukan lembaga formal pengendali yang secara yuridis berwenang untuk itu. Pengendalian kegiatan dan operasionalisasi industri, dalam prakteknya terwujud dalam konsep dan program kerja sistematis dalam bentuk perlindungan dan pengelolaan lingkungan hidup. Pengelolaan lingkungan hidup harus bermuara pada terjaminnya kelestarian lingkungan, seperti tercantum dalam Pasal 1 butir 2 Undang-Undang No.32 Tahun 2009 tentang Perlindungan dan Pengelolaan Lingkungan Hidup.

Abstract

Pemanfaatan air tanah yang cenderung meningkat akan mengakibatkan berbagai dampak negatif, berupa penurunan muka air tanah, penurunan mutu air, dan penurunan tanah (Subsidence) akibat kosongnya rongga-rongga didalam tanah karena hilangnya air. Salah satu cara untuk mengetahui stratigrafi batuan dan kondisi akuifer di dalam tanah adalah dengan teknik geolistrik, karena geolistrik merupakan alat untuk mendeteksi perlapisan batuan di dalam bumi. Untuk mengetahui perlapisan batuan dan kondisi akuifer di Desa Balunijuk maka dilakukan pendugaan geolistrik pada 4 titik sampel dengan sebaran berdasarkan topografi Desa Balunijuk, Adapun metode geolistrik yang digunakan adalah rangkaian elektroda menurut konfigurasi Wenner. Dari ke empat titik pendugaan geolistrik tersebut maka diperoleh daerah penelitian yang diwakili penampang E-F merupakan daerah paling potensial mengandung air tanah yang tersimpan dalam akuifer dangkal, dengan demikian di daerah ini dapat dilakukan kegiatan pengeboran air tanah sedangkan untuk daerah penelitian yang diwakili penampang C-D merupakan alternatif daerah yang cukup potensial mengandung air tanah yang tersimpan dalam akuifer dangkal. Namun lapisan pasir yang mengandung air tanah di daerah ini tidak setebal lapisan pasir yang dimiliki daerah penelitian dalam penampang E-F. Sedangkan untuk Lapisan batuan di Desa Balunijuk terdiri dari 3 bagian yaitu: lapisan lempung pasiran dengan nilai tahanan jenis 165-18.207 Ωm, lapisankrikil pasiran dengan nilai tahanan jenis 22,5-258 Ωm, dan lapisan lempung dengan nilai tahanan jenis 2,04-20,5 Ωm serta hasil analisis air permukaan bahwa air permukaan yang diambil dari semua titik sampel tidak layak di jadikan sebagai sumber air baku air minum.
