Abstract

Daerah Arinem berada dalam wilayah Kabupaten Garut. Termasuk dalam endapan epitermal karena berada pada daerah busur kepulauan Sunda (Sunda Arc) yang terletak di kepulauan Indonesia di sisi selatan dari Sundaland dan lempeng Eurasia. Dalam kegiatan eksplorasi endapan mineral bijih, penting adanya pemahaman tentang mineral. Penelitian ini bertujuan untuk mengidentifikasi karakteristik mineralisasi endapan epitermal prospek Arinem berupa tekstur, morfologi, ukuran dan kehadiran mineral bijih yang nantinya dapat membantu untuk interpretasi paragenesanya. Studi dilakukan dengan mengamati 16 sampel hand speciment yang ditemukan dipermukaan serta 12 sampel yang berasal dari 1 lubang bor level 170-210 meter. Sampel-sampel tersebut diamati menggunakan mikroskop polarisasi refraksi-refleksi. Sementara 4 sampel terpilih digerus menjadi fraksi berukuran lempung dan dianalisis dengan menggunakan metode X-ray Diffraction (XRD) untuk mendeteksi mineral-mineral lempung dan asosiasi mineral ubahan lainnya. Tekstur kuarsa yang hadir pada lokasi penelitian berdasarkan pengamatan megaskopis, umumnya didominasi oleh tekstur saccharoidal, colloform, comb, zoned crystal, lattice bladed, banded, dan massif. Mineral bijih yang teridentifikasi umumnya didominasi oleh mineral base metal dengan paragenesa secara berurutan adalah pirit, sfalerit, kalkopirit, galena, limonit, jarosit dan malasit. Alterasi pada pada lokasi penelitian dicirikan oleh keberadaan kuarsa-kaolinit-illit, serta kuarsa-kaolinit-klorit-kalsit yang mencirikan zona propilitik. Hasil penelitian disimpulkan bahwa tipe mineralisasi pada prospek Arinem merupakan tipe epitermal sulfidasi rendah.

Abstract

Water is a natural resource that is crucial for the survival of all living beings, including humans. The quality of water is an important factor that can have a significant impact on human health. To ensure the well-being of the community, water quality testing was conducted at 2 drilled wells that are being used by residents of Anaiwoi Village. Based on the water quality testing results, it was found that the pH value at point 1 was between 4,6-4,8, while at point 2, it was between 4.6 - 5.9. Unfortunately, the pH values at both points were below the Environmental Health Quality Standards. On the other hand, the Total Dissolved Solid (TDS) parameters at both points were found to be within the Environmental Health Quality Standards. This is because the TDS values obtained were less than 300 mg/L or less than 300 ppm.

Abstract

The current advancements in the automotive industry highlight the critical need for electric vehicles, which require a reliable supply of nickel for battery production. A potential nickel source is Ferronickel's local content, which can be used as a secondary resource. However, research on converting smelted Ferronickel into electrolytic nickel is still limited. This study aims to examine the effects of electrolyte molarity and applied voltage during the electrolysis process for refining Ferronickel. The molarities of HCl employed in this research are 0.1, 0.25, 0.5, 0.75, and 1 M for 2 hours. Additionally, the molarities of HCl are set at 2, 3, and 4 M for 6 hours. Further experiments were performed using varying voltages of 1, 2, 4, 6, and 8 V while keeping the solution concentration constant at 1 M and maintaining an electrolysis duration of 2 hours. The electrolysis solution was subsequently analyzed using the AAS (atomic absorption spectrophotometry) test. The results indicated that higher molarity levels were associated with increased current, resulting in faster reaction rates and greater solubilization of nickel metal. The Ni concentration rose with higher molarity, increasing from 76.50 mg/L in .25 M HCl to 91.88 mg/L in 1 M HCl. In contrast, the Fe concentration remained nearly constant across various molarity levels, ranging from 11.81 mg/L in .25 M HCl to 11.95 mg/L in 1 M HCl, suggesting a minimal influence of molarity below 1 M. Fe exhibited a strong positive correlation with increasing electrolyte molarity, showing a significant rise in concentration from 49.06 g/L at 2 M to 90.17 g/L at 4 M. Ni showed a more modest response to elevated molarity, with concentrations increasing from 11.95 g/L at 2 M to 22.70 g/L at 4 M. The Ni concentration increased with the applied voltage up to 6 V, reaching 95.57 mg/L, but then decreased to 77.67 mg/L at 8 V, indicating that the optimum voltage is 6 V. The Fe concentration displayed slight fluctuations but remained relatively stable across different voltage levels, measuring 11.81 mg/L at 1 V and 12.28 mg/L at 8 V, indicating that the applied voltage does not significantly influence Fe concentration in the solution.

Abstract

Mining is one of the activities that use natural resources. Mining activities can have both positive and negative impacts on local governments and communities. The positive impacts can lead to an increase in regional income, while the negative impacts are reduced land activity, erosion, landslides and disturbance of flora and fauna. The knowledge of the people living around the mining area about the impact of mining activities has a major impact on environmental sustainability. This community service was conducted at Sulaho Village, IV Lanipa-nipa Hamlet, Lasusua District, North Kolaka Regency. The service method is carried out with lectures/socialization of the planting technique procedures as well as the direct planting of mangrove trees in the beach area. As a result of the engagement, the team received active responses from the community by asking questions, great enthusiasm for participating in direct field planting activities, and commitment to always protect the surrounding area from the negative impacts that mining activities could cause. All parties involved in mining activities are expected to participate in protecting the environment around the mining area

Abstract

PT Putra Mekongga Sejahtera is a nickel laterite mining company located in Pomalaa District, Kolaka Regency, Southeast Sulawesi Province. In a mining activity, many factors affect the aspects of production achievement, one of which is the haul road. Haul roads make a major contribution to smooth transportation operations if the road geometry is in accordance with the dimensions of the conveyance used, then the production target of 80,000 tons / month can be achieved. The current field conditions in terms of road geometry are considered unrepresentative for the movement of hauling equipment and can interfere with mining activities. Based on actual haul road geometric measurements between 5.41-16.98 meters while the theoretical road width for straight roads is 8.72 meters. The actual bend road width ranges from 5.50-15.10 meters while the theoretical bend road width is 14.32 meters. The actual road slope ranges from 0.35% to 17.30% while the maximum road slope is 12%. After evaluation, there are 4 straight road segments that need to be increased in width, namely segments AB, BC, CD and DE and 5 segments of bend road width, namely segments AB, BC, CD, DE and EF, as well as grade reduction in segments AB, BC, DE and EF. Hino FM 260 JD dump truck production before road geometry improvement is 3029 tons/day or 78761.75 tons/month. Hino FM 260 JD dump truck production after ideal road geometry improvement is 3143 tons/day or 81724.38 tons/month.
