Abstract

Kegiatan penelitian dilakukan pada lokasi pertambangan emas rakyat tanpa izin didaerah Kelurahan Petuk Barunai, Kecamatan Rakumpit, Kota Palangka Raya. Penelitian ini bertujuan untuk mengetahui dampak kegiatan pertambangan emas rakyat skala kecil terhadap kondisi lingkungan berdasarkan pengujian sampel air Sungai Takaras dan sampel tanah di laboratorium. Tujuan berikutnya yaitu untuk menganaisis strategi alternatif pengelolaan lingkungan pada lokasi pertambangan emas tersebut. Hasil penelitian menujukkan bahwa nilai Total Suspend Solid (TSS) dan derajat keasaman air (pH) melewati ambang batas Baku Mutu Air. Pada tanah, kandungan C-Organik (rendah), N-Total (tinggi), P2O5 (sangat rendah), K-Total (sangat tinggi), KTK (rendah), pH tanah (asam). Berdasarkan dari hasil analisis SWOT didapatkan 1 buah strategi prioritas yaitu strategi WT dengan skor total 6,433. Strategi alternatif berdasarkan hasil analisis SWOT adalah fitoremediasi, revegetasi lokasi penambangan emas yang terbengkalai, dan sosialisasi kepada masyarakat Petuk Barunai khususnya penambang emas.

Abstract

Takaras River is a river basin that is vulnerable to pollution, particularly from the mercury usage in small-scale gold mining. This study aims to identify water quality based on mercury (Hg)and pH levels in the Takaras River. Samples were taken at two locations using a purposive sampling method. Results showed indications of mercury use on former gold mining land around the Takaras River altought the mercury content level was below 0.075 µg/L or 0.00075 mg/L in sample 1 and 2. Based on the test results, the acidity level (pH) in the two water samples from Takaras River is 3.86 and 3.84 in sample 1 and 2, compared to the maximum pH quality standard of 6-9 for Class II water, it is concluded that the scale of acidity in Takaras River is very low, indicating that the water quality in the Takaras River is highly acidic, abnormal, and shows signs of serious pollution. The implications of low pH levels in the Takaras River can cause damage to the Takaras River ecosystem, a decline in soil quality and fertility, and an increase in heavy metal toxicity in the environment surrounding the river.
