Abstract

Studi ini dilakukan untuk menganalisis pencemaran logam berat hasil pengolahan emas tambang rakyat terhadap air Sungai Kalemendo yang diduga mengandung logam berat yaitu Merkuri, Sianida, Tembaga, Timbal, dan Besi. Dilakukan pemantauan kondisi sungai, pengambilan sampel air, pengujian laboratorium, serta melakukan penentuan status mutu air dengan menggunakan Metode Storet. Hasil kualitas air pada Sungai Kalemendo sebagian besar belum memenuhi Baku Mutu Air Limbah Bagi Usaha dan atau Kegiatan Pertambangan berdasarkan KepMen LH No 113 Tahun 2003, sedangkan status mutu air termasuk pada kualitas air yang tercemar berat berdasarkan KepMen LH No. 115 Tahun 2003. Kualitas air Sungai Kalemendo berdasarkan PP No 82 Tahun 2001 untuk kriteria kelas mutu air ditemukan bahwa Ph, TSS, logam Fe, Pb dan Cu tidak memenuhi parameter Kelas I dan II. Kandungan logam berat Cn memenuhi baku mutu kelas I dan II, kandungan Ph, TSS, logam Fe, Pb dan Cu pada air sungai belum memenuhi kriteria kelas III.

Abstract

Aktivitas pertambangan akan memberikan limbah bagi lingkungan. Limbah tersebut berupa logam berat yang mudah terakumulasi dengan air. Logam berat dalam air sangat penting bagi organisme hidup tetapi jika konsentrasi di luar batas yang direkomendasikan oleh berbagai organisasi nasional dan internasional dapat menyebabkan gangguan fisiologis. Kelebihan ini di lingkungan air terjadi, melalui berbagai proses dan jalur, oleh sumber alami dan antropogenik. Akumulasi logam-logam ini dalam organisme hidup dapat menjadi racun dan karsinogenik karena sifatnya yang tidak dapat terurai secara hayati. Untuk tujuan ini air, manajemen kualitas dan penilaian dalam logam berat adalah sangat penting. Status kualitas air secara keseluruhan dan identifikasi sumber asal logam berat diperlukan untuk pengelolaan kualitas air. Indeks polusi logam berat (HPI) dan Analisis faktor (FA) adalah pendekatan yang paling nyaman dan efektif untuk menilai status kualitas air dan mengidentifikasi sumber polutan. Makalah ini mengulas tentang sumber, dampak terhadap kesehatan manusia dan teknik penilaian pencemaran logam berat di lingkungan perairan serta. teknik pengolahan air limbah untuk menghilangkan logam berat tersebut

Abstract

Dalam kegiatan penambangan memberikan dampak positifnya untuk memenuhi kebutuhan manusia dalam membangun infrastruktur, sarana prasarana dan bahan galian yang diambil dapat dimanfaatkan.sedangkan Dampak negatif dari kegiatan pertambangan adalah terjadinya perubahan bentuk lahan yang ada pada kawasan pertambangan dimana dari perubahan bentuk lahan tersebut pada umumnya mengakibatkan erosi dan gerakan massa tanah karena pertambangan yang dilakukan secara tradisional umumnya tidak berwawasan lingkungan karena tidak memiliki perencanaan penambangan. Pada lahan miring sering tidak memperhatikan tindakan konservasi tanah terutama pada penggunaan lahan. oleh karena itu, perlu dilakukan analisis prediksi laju erosi tanah. Penelitian ini dilakukan untuk mengetahui tingkat erosi yang terjadi dan laju erosi tanah serta arahan untuk melakukan konservasi disekitar area penambangan dengan melihat parameter erosivitas hujan, erodibilitas tanah, panjang dan kemiringan lereng, Praktek pengelolaan lahan,Serta praktek pengelolaan tanaman sehingga dapat mengetahui tingkat erosi dan arah penyebaran erosi yang terjadi di daerah penelitian dengan menggunakan pendekatan metode USLE, metode MUSLE dan metode RUSLE serta memberikan arahan untuk melakukan konservasi lahan.

Abstract

This study aims to make a technical design for coal mining in the first quarter of 2022 which includes a mining progress design, disposal design. The research methodology includes literature study to find literature references that directly support and relate to mining technical design. Then conduct orientation and observation of the problems that exist in the field. The data needed in this study are primary data and secondary data. The data that has been obtained is then processed and analyzed to produce a conclusion in the form of a mining technical design that meets the coal production target of 135,000 tons/quarter. Mining progress plan is made based on a predetermined production target of 135,000 tons/ quarter of coal. The results of the reserve based on the design in January 2022 obtained overburden volume of 166,637 BCM, coal of 45,348 tons with SR = 3.67: 1, in February 2022 obtained overburden volume of 167,655 BCM, coal of 45.017 tons with SR = 3,72 : 1, in March 2022 obtained overburden volume of 166,541 BCM, coal of 45,127 tons with SR = 3.69 : 1. The disposal design is located 1,893.09 m south of the pit. The total disposal capacity based on the design is 552,763 CCM with an area of 9.72 Ha. The amount of disposal capacity is 2.5% higher per year against the reserve based on the design with the type of embankment applied is the Terrance Dump. The type of Terrace Dump embankment was chosen because the topography in the study area is not too steep.

Abstract

Acid Mine Drainage is one of the environmental problems most frequently faced by the mining industry. Acid mine drainage occurs when sulfide minerals such as pyrite (FeS2) and marcasite (FeS3) are exposed due to mining activities such as dismantling overburden and coal excavation, causing them to react with oxygen and water. Based on the literature review, there are several adsorbents used in the management of acid mine drainage to reduce heavy metals, one of which is coconut fiber. To reduce the impact of acid mine drainage, an effective and efficient management method is needed. An effective method for managing acid mine drainage is to reduce heavy metals using coconut fiber carbon impregnated with a solution of mercaptobenzothianol (MBT). The research results stated that the absorption of heavy metals for the optimum value in coconut fiber carbon impregnated with mercaptobenzothianol (MBT) was 99.93%, however this method was not efficient because it was quite expensive. The most efficient method is the acid mine drainage method using coconut fiber because it is economical and environmentally friendly.

Abstract

One of the energy requirements for fuel is in the form of solid hydrocarbons and as basic materials or feedstocks. Coal is formed from deposits of organic plant compounds that grow in an oxygen-free environment and are influenced by temperature and pressure for a long time. Based on the coal formation process, coal from the highest to the lowest level is anthracite, bituminous, sub-bituminous, and lignite. Low-grade coal has a faster oxidation rate than high-grade coal because it contains inherent moisture, oxygen, and carbon in large quantities, has high porosity, and causes an increase in activation energy resulting in evaporation and a continuous increase in temperature causing spontaneous combustion. Monitoring and control of coal, especially in the stockpile area as a temporary storage place, is carried out to prevent oxidation and self-burning, namely by arranging the piling pattern and applying demolition principles by taking into account the length of the pile, forming the design of the stockpile base surface, calculating the volume, height, side slope, and distance between piles, as well as taking into account wind speed and direction, which greatly influence particle size, porosity, and the rise in temperature of the coal during self-heating. Efforts to handle self-heating in coal can be made by creating drainage in the stockpile area, reducing the height, and forming a slope angle of 15–30° to facilitate compaction of the coal pile so that it can be stored for a long time, as well as minimizing losses from spontaneous combustion and early self-heating detection for safe coal storage.

Abstract

This mineral processing aims to separate valuable minerals from their impurities using mechanical methods by utilizing the physical and chemical properties of the minerals. One of them is by using gravity concentration with a sluice box tool. It is known that to achieve the desired recovery, this tool requires supporting parameters for optimal recovery, including dimensions and materials, riffles, slopes, water discharge, and carpet types. The purpose of this paper is to determine whether several supporting parameters really affect the results of metal mineral processing with the limitation of the problem is the influence of supporting parameters in various previous research results. The results of the review show that the supporting parameters affect the processing results. In addition, the parameters also influence each other. If the results of these parameters are not accurate, the processing results will also be less than optimal and material sedimentation will occur.
