Abstract

One of Indonesia’s potential gold ore deposits is found in the Bolaang Mongondow area of North Sulawesi Province. This research is one of the initial studies conducted to determine the metal content of gold in ore deposits based on the results of Au extraction using aqua regia. It is known that several operating parameters determine the success rate of the leaching process. One of these parameters is the leaching time. The leaching time ranges used in the study were 5, 10, 20, 60, and 120 minutes. Based on the variation of the leaching time applied to the leaching process, it will also be known how much mass of dissolved Au metal is. The leached filtrate obtained was then analyzed for its concentration using AAS (Atomic Absorption Spectrometry) instrument. The AAS data were then processed using x and y curves to obtain the optimum leaching time, and the mass of dissolved Au metal was obtained using the equation. The results showed that the optimal time for the hydrometallurgical process in gold ore deposits was 120 minutes with an Au concentration of 1.67 mg/L.

Abstract

Kegiatan peledakan akan menimbulkan dampak yang berisiko bagi lingkungan sekitar, salah satunya flyrock (batu terbang) hasil ledakan. Lemparan fragmen batuan yang melewati radius aman dapat merusak peralatan, mengakibatkan cidera, dan kehilangan nyawa pada manusia. Oleh karena itu digunakan balldeck sebagai instrumen tambahan untuk meminimalisir flyrock. Tujuan penelitian ini adalah untuk mengetahui ukuran geometri peledakan yang digunakan, mengetahui cara meminimalisir flyrock pada saat peledakan, dan mengetahui cara perhitungan hasil lemparan maksimal flyrock secara teoritis dengan penggunaan balldeck. Metode penelitian dilakukan dengan cara pengumpulan data berupa geometri peledakan, data jarak lemparan maksimum flyrock  sebelum dan setelah menggunakan balldeck. Hasil penelitian diperoleh hasil rata-rata volume geometri peledakan yaitu 46.231,94 BCM, hasil rata-rata lemparan maksimum flyrock sebelum menggunakan balldeck 149,1 m, hasil rata-rata lemparan maksimum flyrock menggunakan balldeck 58,7 m, dan hasil rata-rata jarak lemparan maksimum flyrock menggunakan balldeck berdasarkan teori Richard and Moore, yaitu 80,43 m (Face Burst) dan 59,54 m (Cratering ). Adapun faktor yang meminimalisir flyrock yaitu kedalaman lubang tidak dangkal, kolom stemming tidak pendek, dan juga penggunaan balldeck di dalam lubang bor.

Abstract

Mining materials can be in the form of material (over-burden) and potentially contain sulfide minerals, the research location is a former iron ore mining, it is known that iron ore is an acid mine drainage forming material. This characterization test of acid mine drainage forming samples can be used as a consideration in environmental management design to minimize unwanted environmental impacts. This study aims to analyze the mineralogical content of rocks, the potential of rocks as acid mine drainage formers, and determine management methods if the potential for acid mine drainage is indicated. The samples used were 5 rock samples in the pit and disposal, using petrography, mineragraphy, and XRD mineralogy analysis to determine the mineral composition contained, and kinetic testing to determine the reaction rate of acid mine drainage formation. The results of the analysis obtained the composition of metal minerals contained in samples 4 and 5, namely pyrite, hematite, magnetite, and geotite. Whereas in samples 1, 2, and 3 not enough metal minerals were detected. The results of the kinetic test analysis produce accurate data for samples 4 and 5 which have low or acidic pH values 6. So it can be concluded that the potential for the formation of acid mine drainage is found in samples in the disposal, namely iron ore with a low pH value 6 (acidic), methods that can be used in the process of preventing and controlling acid mine drainage can be done passively by using NAF material to stockpile polluted PAF material.

Abstract

Coal in Indonesia is widely used for both export and domestic industrial needs. Domestically, it is widely used for the textile industry, power plants, and the cement industry. Coal consumption for the cement industry in Indonesia in 2022 is up to 15 million tons. In the cement industry, coal is used as a basic material for fuel in kilns. For its utilization, coal needs to know its properties. These properties can be known by proximate analysis, sulfur content analysis and calorific value. Therefore, this research aims to find out and determine whether the quality of Bonto Matinggi coal is in accordance with the coal specifications needed in the cement industry. The research method was carried out by taking two coal samples directly in the research area, namely SA I coal sample and SA II coal sample. The coal samples were then prepared and further analyzed. Analysis of coal sample quality was carried out by proximate, sulfur and calorie analysis methods. The results of proximate analysis show that the moisture content in air dried both samples have a value that is not too significant with an average value of 6.29% adb; ash content of 19.99% adb; volatile matter of 46.79% adb and fixed carbon of 39.86% adb as well as sulfur content of 0.39% adb and calories with an average of 4,692.92 cal/g. The coal in the study area does not qualify as a basic material for fuel in kilns in the cement industry. The coal in the study area, if classified according to the Classification of in Seam Coal 1998, is classified as low grade coal (according to ash content) and the coal rank includes bituminous rank (medium rank).

Abstract

Sumberdaya dan cadangan bijih besi laterit Indonesia sangat melimpah sehingga memberi potensi untuk dimanfaatkan sebagai alternatif bahan baku pembuatan baja, mengingat kebutuhan besi baja tiap tahunnya meningkat. Pada penelitian ini dilakukan transformasi fasa goetit menjadi hematit secara mekanokimia untuk meningkatkan kandungan Fe pada bijih besi laterit. Percobaan secara mekanokimia dilakukan dengan menvariasikan waktu penggerusan 5 – 50 jam, 20 – 50% persen volume mill dan jenis bola penggerus. Hasil karakterisasi menunjukkan bahwa bijih besi laterit asal Pulau Sebuku, Kalimantan Selatan bersifat ferromagnetik yang didominasi oleh goetit (FeOOH) dan maghemit (γFe2O3) dengan kadar Fe 42,68%. Transformasi fasa goetit menjadi hematit dan maghemit menjadi magnetit secara sempurna terjadi setelah 50 jam penggerusan, pada persen volume mill terbaik 50%, dan jenis media bola penggerus baja dengan kadar Fe 53,03%. Distribusi ukuran partikel D90 54,30 nm. Penggerusan secara mekanokimia berpengaruh pada sifat kemagnetan bijih besi laterit yang semula dengan nilai intensitas medan magnet 6,23 emu/gram naik menjadi 9,55 emu/gram.

Abstract

Pyrolysis is a process of chemical decomposition of materials through a heating method in the absence of oxygen or a little oxygen. The utilizing coal as a raw material for making liquid smoke, it is hoped that it will be able to produce pesticides that have economic value and can be used as a termite exterminator. The use of coal as a raw material for making liquid smoke is expected to produce pesticides that have economic value and can be used as a termite repellent. This research aimed to determine the optimum concentration and time of liquid coal smoke as a pesticide against termite insect mortality (Coptotermes curvignathus Holmgren). The method used is the coal pyrolysis process at a temperature of 300 0C. The process of testing the mortality of termites with time and concentration variables. The determination of the liquid smoke content of coal is carried out by qualitative and quantitative analysis. The results showed that the optimum time for termite mortality was 25 minutes with an optimum concentration of 80%, where the termite mortality was obtained by 100%. Based on the results of UV/VIS Spectrophotometer Analysis, the sulfur content of liquid coal smoke was 46.92 mg/kg, and the degree of acidity (pH) was 3.00. The acidity content is high enough to allow pesticides from liquid coal smoke to be widely used in agriculture.
