Abstract
INTISARI Daerah penelitian ini dilakukan di PT Nusa Halmahera Minerals yang berada di desa Tabobo, Kecamatan Malifut, Kabupaten Halmaher a Utara, Propinsi Maluku Utara. Luas daerah PT. Nusa Halmahera Minerals yaitu 29.622 hektar. Secara geografis terletak pada koordinat 127º43’ BT dan 1º07’ LU. PT Nusa Halmahera Minerals merupakan perusahaan tambang emas yang memiliki beberapa daerah operasi penambangan yaitu Tambang Gosowong ( open pit mine ), Tambang Toguraci ( underground mine ) dan Tambang Kencana ( underground mine ) . Penelitian yang dilakukan menggunakan metode survey lapangan, metode sampling air sungai, metode analisis laboratorium. Unt uk metode evaluasi menggunakan yaitu metode kuantitatif dengan cara membandingkan hasil la boratorium dengan Baku Mutu PP Nomor 82 Tahun 2001 kelas 2 dan Kepmen LH No 202 Tahun 2004. Hasil analisis dan evaluasi data, menunjukka n bahwa kegiatan pembuangan air tambang terhadap kualitas air sungai Sambiki dan Bora di titik outlet settling pond (RSPK Outlet ) , sungai Sambiki (titik CSS I, CSS II, CSS III, SS10DS u/s dan SS10DS d/s) dan sungai Bora (SB15TD u/s dan SB15TD d/s) tidak menim bulkan pencemaran pada kondisi air sungai. Berdasarkan hasil analisis di laboratorium PT Nusa Halm ahera Minerals menunjukkan bahwa kadar unsur pH berkisar antara 6,4-8,34 dengan standar baku mutu yang ditetapkan 6-9, untuk kadar unsur TSS yaitu 5-31 mg/l dengan standar baku mutu T SS yaitu 50 mg/l berdasarkan peruntukan air kelas 2 untuk PP nomor 82 Tahun 2001 dan untuk Kepmen LH Nomor 202 tahun 2004 yaitu 200 mg/l, serta kadar DO dengan nilai berkisar antara 4,43-7,89 mg/l. Untuk kandungan logam berat (As, Cd, Cr, Cu, Pb, Hg, Ni dan Zn ) yang di analisis di laboratorium Water Laboratory Nusantara (WLN) Manado hasilnya menunjukkan tidak melebihi baku mutu baik berdasarkan PP nomor 82 Ta hun 2001 dan Kepmen LH Nomor 202 tahun 2004. Kata kunci: air tamba ng, kualitas air sungai ABSTRACT The area of research is done in PT Nu sa Halmahera Minerals in the village Tabobo, District Malifut, North Halmaher a, North Maluku. The total area of PT. Nusa Halmahera Minerals is 29,622 hect ares. Geographically, it is located at 127º43' EL and 1º07' NL. PT Nusa Halmaher a Minerals is a gold mining company that has mining operations are some ar eas Gosowong Mine (open pit mine), Toguraci Mine (underground mine) and Kencana Mine (underground mine). Research conducted using field surveys, river water sampling methods, laboratory analytical methods. For evaluati on of the method usi ng the quantitative method by comparing the laboratory result s with the Quality Standards Regulation No. 82 Year 2001 Class 2 and Decree No. 202 LH 2004. The results of the analysis and ev aluation of data, suggesting that the activity of the mine drainage water quali ty and Bora Sambiki settling pond at the outlet point (RSPK Outlet), river Sambik i (CSS point I, II CSS, CSS III, SS10DS u/s and SS10DS d/s) and river Bora (SB15TD u/s and SB15TD d/s) does not cause pollution of the river water conditi ons. Based on the results of laboratory analysis of PT Nusa Halmahera Minerals showed that pH levels ranging from 6.4 to 8.34 elements with quality standards set 6-9, to the levels of TSS element is 5- 31 mg/l TSS with the quality standards 50 mg / l based on grade 2 water allotment for the PP number 82 Year 2001 and for LH Decree No. 202 of 2004 which is 200 mg/l, and DO levels with values rangi ng from 4.43 to 7.89 mg /l. For the content of heavy metals (As, Cd, Cr, Cu, Pb, Hg, Ni and Zn) were analyzed in the laboratory Nusantara Water Laboratory (WLN) Manado re sults indicate not exceed the quality standards either under Regulation number 82 of 2001 and Decree No. LH 202 2004. Keywords: mine water, river water quality
