Abstract

Aktivitas penambangan pasir sangat banyak dilakukan di Kelurahan Sei Gohong Kecamatan Bukit Batu dan merupakan salah satu sektor utama mata pencaharian masyarakat setempat. Lubang-lubang bekas tambang pasir yang ditinggalkan tanpa adanya melakukan pengelolaan sehingga sebagian bekas lubang galian tersebut terisi oleh air dan sebagian tidak mengandung air. Berdasarkan latar belakang tersebut maka dilakukan analisis Analisi Kesesuaian Pemanfaatan Air Pada Lubang Bekas Tambang Pasir Di Daerah Kelurahan Sei gohong agar nantinya dapat ditemukan kondisi lubang bekas tambang pasir, kualitas air lubang bekas tambang pasir, dan pemanfaatan air pada lubang bekas tambang pasir. Dari hasil penelitian, kondisi lubang bekas tambang pasir A dan B berumur ± 20 tahun yang dapat dikategorikan lubang bekas tambang usia sedang (setengah matang) dan kondisi air yang berada di lubang bekas tambang setiap musim kemarau tidak akan kering, jadi masyarakat sekitar memanfaatkannya air tersebut untuk mengairi tanaman , mencuci kendaraan dan lain-lain. Berdasarkan hasil uji 4 sampel air dilaboratorium menunjukan hasil tidak  sesuai dengan yang terlampir pada bagian IV lampiran II tentang Baku Mutu Air Danau Dan Sejenisnya pada PP No. 22 Tahun 2021 Standar Maksimum Kelas 4 sehingga pemanfaatnya hanya bisa digunakan untuk mengairi tanaman dan digunakan sebagai penyiraman kebakaran hutan

Abstract

PT. Satria Alam Manunggal merupakan salah satu perusahaan tambang yang terletak di Desa Buhut Jaya, Kecamatan Kapuas Tengah, Kabupaten Kapuas, Provinsi Kalimantan Tengah. Dengan menerapkan sitem tambang terbuka yaitu open pit mine method. Salah satu kegiatan pertambangan yang biasa dilakukan dan tidak dapat ditinggalkan yaitu kegiatan survey. Kegiatan survey digunakan untuk membuat peta topografi area tambang dengan tujuan untuk mengetahui sebaran dan cebakan dari suatu bahan galian yang akan ditambang dan juga untuk menghitung volume overburden, top soil, maupun batuan atau mineralnya. Untuk ntuk menghitung volume overburden yang tergali dapat juga mengggunakan metode truck count dengan menghitung ritase alat angkut dan dikalikan dengan volume vessel yang sudah disepakati Perusahaan. Pada bulan Maret 2024, didapatkan volume overburden berdasarkan joint survey sebesar 313.935,74 bcm sedangkan untuk volume overburden berdasarkan truck count didapatkan sebesar 317.986 bcm. Kedua metode tersebut terdapat perbedaan volume overburden yang tergali dengan deviasi sebesar -1,27% (joint survey kurang 4.050,26 bcm terhadap truck count). Faktor yang menyebabkan deviasi tersebut yaitu adanya data survey progress yang tidak terambil, spasi pengambilan data survey progress yang kurang rapat, adanya material timbunan dalam pit, standar volume vessel tidak sesuai dengan kondisi aktual, dan adanya material sisa pada vessel.

Abstract

Coal mine wastewater typically has acidic characteristics that can pose environmental hazards if not properly treated. This study aims to evaluate the effectiveness of quicklime (CaO) and caustic soda (NaOH) in increasing the pH level of mining wastewater at Settling Pond 1, PT Nantoy Bara Lestari, located in Pandreh Village, Teweh Tengah District, Central Kalimantan. The research employed a jar test method using various dosages applied to 1 liter of water samples. The results indicated that the initial pH of the wastewater was 2.85, significantly below the regulatory standard (6–9). After treatment, both reagents successfully increased the pH of the wastewater, with optimal doses at 0.7 g/L for quicklime and 0.2 g/L for caustic soda. However, caustic soda demonstrated greater effectiveness at lower doses compared to quicklime. These findings suggest that caustic soda may serve as a more efficient alternative for active treatment of mining wastewater. This study is expected to contribute as a reference for pH-based wastewater management in mining operations. Keywords: mining wastewater, pH, quicklime, caustic soda, settling pond

Abstract

Coal is an important energy source that is still widely used in industry, especially the power generation industry, because of its high energy content. However, in the process of handling and storage, coal has the characteristic of being easily oxidized, This oxidation process, if it occurs continuously, can cause internal heat accumulation which eventually triggers spontaneous combustion. This study aims to analyze changes in coal quality before and after spontaneous combustionto find out how spontaneous combustionaffects coal quality in stockpiles. The research method used is a quantitative method where the data from laboratory tests on coal quality before and after spontaneous combustionis analyzed, the comparison of coal quality in stockpile 10 before and after spontaneous combustionis then graphed to see changes in the quality of each parameter. Based on the results of the analysis of changes in coal quality before and after spontaneous combustion, there were significant changes to several coal quality parameters, namely Total Moisture which was originally from 7.06% to 5.50% (down by 1.56%), Moisture which was originally 3.91% to 3.22% (down by 0.69%), Ash Content which was originally 8.84% to 14.67% (up by 5.83%), Volatile Matter which was originally 39.77% to 35.10% (down by 4.67%), Fixed Carbon from 47.48% to 47.01% (down by 0.47%), Sulphur from 0.55% to 0.46% (down by 0.9%), and Calorific value decreased from 6,921 to 6,289 kcal/kg (down by 632 kcal/kg). This decrease in quality has a direct effect on the selling value and efficiency of coal combustion. The existence of an analysis of changes in coal quality due to spontaneous combustioncan help companies to find out how much of an impact losses can be caused by the occurrence of spontaneous combustion. By considering the potential losses due to spontaneous combustion, the company will make efforts to prevent the occurrence of spontaneous combustion in the future to minimize the losses caused.
