Abstract

Penelitian ini bertujuan untuk menganalisis dampak aktivitas pertambangan emas tanpa izin (PETI) terhadap kualitas air Sungai Kapuas di Desa Tumbang Randang, Kecamatan Timpah, Kabupaten Kapuas. Sampel air diambil dari empat titik (permukaan dan dasar sungai di hulu dan hilir), kemudian diuji berdasarkan 10 parameter fisik dan kimia, dan dianalisis menggunakan metode Indeks Pencemaran (IP). Hasil penelitian menunjukkan bahwa beberapa parameter seperti TSS, Cu, COD, dan BOD melebihi baku mutu air kelas I, II, dan III sesuai PP No. 22 Tahun 2021. Nilai IP berada pada kisaran 3,20–3,95, yang menunjukkan status pencemaran ringan. Dengan demikian, kualitas air Sungai Kapuas di lokasi penelitian tidak lagi memenuhi standar air minum tanpa pengolahan. Diperlukan pengawasan dan penertiban terhadap aktivitas PETI serta pengelolaan lingkungan yang berkelanjutan untuk mencegah peningkatan pencemaran.

Abstract

PT Dayak Membangun Pratama is a company engaged in coal mining located in Tumbang Manyangan Village, Tumbang Tambirah, and Penda Pilang, Kurun and Tewah Districts, Gunung Mas Regency, located in Central Kalimantan with an area of 4,88.17 hectares of Borrowing Permit for Use of Forest Area (IPPKH) from the Ministry of Forestry with Decree (SK) Number 24/1/IPPKH/PMDN/2016 with an area of 999.95 hectares. The validity period of the production operation IUP is for 20 (twenty) years starting from November 29, 2011 to November 28, 2031. From the results of observations on seam B3, the time required for the coal getting activity was 4.19 hours with a coal volume of 125.99 tons. So that the productivity of coal getting on seam B3U[1] is 30.07 tons/hour. On seam B1 and Fault B1, the time required for coal getting activities is 3,143 hours with a coal volume of 134.5 tons. So that the productivity of coal getting on seam B1 and Fault B1 is 42.8 tons/hour. In the B23L seam, B23U fault and B3U fault, the time required for coal getting activities is 5.57 hours with a coal volume of 167.62 tons. So the productivity of coal getting on seam B23L, Fault B23U and Fault B3U is 30.01 tons/hour.
