Abstract

The crushing plant in the mining industry produces noise levels above the allowable noise level, potentially causing hearing damage to mining workers. One way to early control this is by mapping the noise distribution in the area. The noise distribution mapping was based on noise intensity. The noise intensity measurement was done using a sound level meter according to Indonesian national standards 7231:2009. The noise exposure analysis was based on the NIOSH formula and Indonesia's national standard 7570:2023. The study's results revealed that noise levels at the source exhibited an intensity of approximately 95-103 dB. The noise propagation pattern extended from the southwest to the northeast, with an intensity of approximately 68-93 dB. The highest noise intensity was observed in the vicinity of the first jaw crusher, exceeding 100 dB, with a daily exposure time in this area of 6-12 minutes. Prolonged exposure to high noise levels can potentially lead to auditory damage. Therefore, the implementation of noise control measures, including using personal protective equipment and the installation of appropriate safety signage, is imperative.

Abstract

The geoelectric method is an effective geophysical method in subsurface mapping by utilizing the electrical properties of rocks. The basic principle of the geoelectric method is to measure resistivity by flowing an electric current into the earth through electrodes. Geoelectrical (resistivity) surveys generally aim to determine the condition or structure of subsurface geology based on variations in rock type resistance. The results of the training showed significant variations in the resistivity of Andesite and Granite rocks, which were indicated as potential resource zones worthy of further exploration. The results of resource potential calculations show that the volume of Andesite is 909,364,491 m³ and the volume of granite is 55,436,878 m³. This training also provides recommendations for residents in Salatiga District, Sambas Regency, to use this as literature to attract investors so they can invest in the area as much as the relevant volume.

Abstract

The Integrated Islamic Elementary School (Sekolah Dasar Islam Terpadu, abbreviated as SDIT) Wisata Hasanah is one of the elementary schools in Pontianak City that implements the independent Murikulum Merdeka. In this curriculum, there is the Pancasila Student Profile Strengthening Project (Proyek Penguatan Profil Pelajar Pancasila, abbreviated as P5), where students actively address relevant issues in their surroundings. In a previous P5 activity, training on waste sorting based on its types—organic and inorganic—was conducted. A field lecture was held at the Final Disposal Site (TPA) of Batu Layang, Pontianak in this community service activity to raise awareness and concern for the environment, develop responsibility, independence, and critical thinking skills. Waste management education needs to be carried out from an early age to produce human resources with expertise in science and technology, in line with achieving Indonesia’s Golden Vision 2045. The students currently in elementary school will be the next generation to continue the nation's development. Activities at the TPA included delivering material, discussions, observations, and student feedback in the form of resumes and responses containing experiences, suggestions, input, and hopes. At the TPA site, students directly observed the facilities, infrastructure, and operational techniques of waste processing. The results of this activity included an increase in students' knowledge about waste management, an understanding of the impact of indiscriminate waste disposal and burning, and a commitment to environmental preservation. Community service is a form of collaboration and knowledge transfer between higher education institutions, elementary schools, and the government (Environmental Agency). Through this activity, it is hoped that students will develop environmental awareness and concern not only at school but also in their surrounding environment.

Abstract

Konsumsi bahan bakar merupakan biaya operasional yang signifikan dalam penambangan terbuka. Penelitian ini bertujuan untuk menganalisis pengaruh kuantitatif dari kemiringan jalan (grade) jalan dan jarak angkut terhadap konsumsi bahan bakar pada dua jenis alat angkut, Mitsubishi Fuso 220 dan Hino 500, di PT. Gilgal Batu Alam Lestari. Penelitian dilatarbelakangi oleh adanya inefisiensi bahan bakar yang ekstrem (0,64 km/liter untuk Mitsubishi Fuso 220 dan 0,38 km/liter untuk Hino 500), yang disebabkan oleh kemiringan jalan kritis sebesar 10,35% dan kondisi permukaan yang buruk di sepanjang jarak angkut. Metodologi kuantitatif dengan metode perhitungan rimpul digunakan untuk mengisolasi dan memodelkan pengaruh kedua variabel pada setiap alat angkut. Hasil penelitian menunjukkan bahwa setiap kenaikan 1% grade pada kondisi jalan ideal menambah konsumsi bahan bakar sebesar 0,209 liter/jam (Mitsubishi Fuso 220) dan 0,396 liter/jam (Hino 500). Model prediksi menunjukkan bahwa setiap penambahan 1 km jarak angkut akan meningkatkan konsumsi bahan bakar sebesar 1,437 liter (Mitsubishi Fuso 220) dan 2,434 liter (Hino 500). Skenario perbaikan jalan terbukti meningkatkan efisiensi Fuel Ratio sebesar 47,6% untuk Mitsubishi Fuso 220 dan 41,2% untuk Hino 500.

Abstract

Indonesia's largest bauxite reserves are in the province of West Kalimantan, which is 703 million tons Bauxite is formed from rocks with a high relative aluminum (Al) content, low iron (Fe) content, and small amount of quartz. The mineralogy and characteristics of lateritic bauxite deposits are closely related to several factors, one of which is the texture and composition of the bedrock such as color, mineral composition, and shape of the ore. This study discusses the genetic type of bauxite deposits based on mineralogy and geochemistry using mineragraphic, XRD, and XRF methods. The primary data from bauxite ore samples were collected from the stockpile of PT. Dinamika Sejahtera located in Toba area. The quantitative result of the geochemical analysis indicates a higher amount of alumina observed using the XRF method. Granodiorite bauxite, which is bauxite coming from granodiorite bedrock, generally has abundant geochemical elements, especially SiO2 and Al2O3. The lateritic bauxite type in the Toba area is a product of granodiorite weathering from the Sepauk Tonalite formation is embedded within a clay matrix which exhibits a brownish to red color with coarse to boulder-size of concretion texture without relict. Some important elements in bauxite laterite deposits are Al, Fe, Si (Silicon), and Ti (Titanium). The comparison between Al and Si values is a benchmark for the economics of bauxite mines. Gibbsite is the major mineral in the bauxite ore, while hematite, goethite, kaolinite, and quartz are the accessory minerals. The deposit is recognized as Low-Fe bauxite due to comparing Al2O3, Fe2O3, and Si2O3 concentrations. The weathering process has altered the primary texture, remaining resistant and secondary minerals. The petrographic analysis shows the replacement of Gibbsite as bauxite ore which presents as kaolinite replacement and fills the mineral cracks. The result of this study is expected to be useful in determining the exploration method for the bauxite deposits.
