type: item
description: Dalam memaksimalkan kegiatan penambangannya, perusahaan secara rutin wajib melakukan kegiatan pengawasan, pengendalian dan tindakan konstruktif dengan menerapkan standar baku mutu terhadap kualitas bahan galian dan limbah cair terhadap kegiatan penambangan yang mengandung logam berat. Penelitian ini berfokus pada limbah Cr6+ yang bersumber dari endapan nikel laterit yang dihasilkan dari penambangan PT Konutara Sejati. Tujuan penelitian yaitu menganalisis potensi pembentukan chromium hexavalent (Cr6+) menggunakan metode analisis mineralogi dan analisis geokimia untuk mengetahui mineral-mineral terkandung dan kadar logam berat pada endapan nikel laterit yang menjadi pembawa chromium hexavalent (Cr6+). Sampel air settling pond dianalisis menggunakan metode pengujian fisika dan kimia, untuk mengetahui tingkat pencemaran logam berat Cr6+. Jenis sampel yaitu limonit, saprolite dan bedrock pada BLOK D titik GK-1. Hasil penelitian ditemukan mineral talc, lizardite, geothite, magnetite, hornblende, forsterite, spinel dan enstatite. Kadar unsur logam berat Cr6+ berkisar 27,7 – 52,1 ppm, Ni berkisar 2,259 – 10,253 ppm, Fe berkisar 39.685 – 167.534 ppm dan Pb berkisar <3 ppm. Hasil analisis sampel air pada settling pond ditemukan parameter TSS pada inlet yaitu 87 mg/l dan outlet 143 mg/l, nilai pH inlet 7,48 dan outlet 7,08. Kadar logam berat Cr6+ pada sampel air ditemukan berkisar <0,028 mg/l. Berdasarkan hasil analisis geokimianya potensi pembentukan unsur logam berat berbahaya Cr6+ ditemukan pada pada 3 sampel tanah sebanyak 27,7 ppm hingga 52,1 ppm kandungan Cr6+. Berdasarkan pemantauan air limbah pada settling pond potensi pencemaran unsur Cr6+ tidak ditemukan melebihi batas baku mutu lingkungan yaitu 0,1 mg/l. Kromium terdapat hampir pada seluruh lapisan litologi laterit, sehingga kegiatan penambangan memiliki potensi yang besar dalam menghasilkan kromium.

Analisis Pengaruh Temperatur, Lama Timbunan, dan Dimensi Timbunan Terhadap Terjadinya Swabakar pada ROM Batubara PT Triaryani
type: item
description: Swabakar (self-heating) pada batubara merupakan permasalahan serius yang terjadi akibat reaksi oksidasi yang menghasilkan panas secara bertahap hingga memicu kebakaran spontan. Penelitian ini bertujuan untuk menganalisis pengaruh temperatur, lama timbunan, dan dimensi timbunan terhadap potensi terjadinya swabakar pada ROM batubara di PT Triaryani. Penelitian dilakukan di ROM PT Triaryani, Sumatera Selatan, selama Februari hingga Maret 2025 menggunakan pendekatan kuantitatif dengan metode regresi linier sederhana dan analisis deskriptif. Data primer dikumpulkan melalui pengukuran temperatur batubara pada 10 titik timbunan bagian crush, pengamatan dimensi fisik timbunan, serta arah dan kecepatan angin. Sedangkan data sekunder meliputi lama timbunan dan curah hujan. Sebanyak 88 kejadian swabakar tercatat, dengan temperatur maksimum mencapai 483,9°C. Hasil analisis menunjukkan hubungan yang kuat antara umur timbunan dengan peningkatan temperatur, ditunjukkan oleh nilai koefisien determinasi R² sebesar 80,25%. Dimensi timbunan yang melebihi standar, seperti tinggi 10 meter dan sudut kemiringan 43°, memperbesar luas permukaan yang terpapar angin, meningkatkan tekanan beban timbunan, dan mempercepat akumulasi panas yang memicu swabakar. Pola penumpukan jenis chevcon turut memperburuk kondisi karena membentuk sisi miring luas yang tidak dipadatkan secara optimal. Untuk meminimalkan risiko swabakar, disarankan penerapan sistem FIFO, pemadatan tiap lapisan, serta pengaturan arah dan bentuk timbunan sesuai arah angin dominan.

Analisis Pengaruh Pengotor Terhadap Material Limonit Pada Proses Penambangan Metode Selective Mining Sebagai Bahan Baku Baterai Kendaraan Listrik
type: item
description: Peningkatan penggunaan kendaraan listrik di Indonesia menunjukkan perkembangan signifikan. Peningkatan ini didorong oleh persepsi bahwa kendaraan listrik lebih ramah lingkungan dibandingkan kendaraan berbahan bakar fosil. Saat ini, sebagian besar kendaraan listrik menggunakan nikel sebagai salah satu bahan utama dalam komponen baterainya. Hal ini disebabkan oleh karakteristik baterai lithium yang mengandung nikel yang mampu menyimpan energi dalam jumlah lebih besar dan memungkinkan kendaraan menempuh jarak yang lebih jauh dalam sekali pengisian daya. Limonit merupakan salah satu jenis bijih nikel laterit, bijih limonit umumnya mengandung berbagai unsur pengotor, pengotor ini disebabkan oleh tercampurnya material atau mineral yang menyebabkan penurunan signifikan terhadap kadar nikel dalam bijih tersebut. Salah satu metode yang dapat digunakan untuk mengidentifikasi unsur unsur pengotor dalam sampel limonit adalah Energy Dispersive X-Ray Fluorescence(EDXRF). EDXRF merupakan metode analisis yang memanfaatkan sinar-X untuk mendeteksi dan menganalisis komposisi kimia dalam suatu sampel secara non-destruktif. Penelitian ini dilakukan untuk mengetahui hasil pencampuran material beserta dampak dan pengaruh dari kontaminasi pada material yang dijadikan sebagai bahan baku baterai kendaraan listrik dari proses pengolahannya dipertambangan. Berdasarkan hasil penelitian ini diperoleh Hasil analisa sampel blending antara material limonit dengan material pengotor atau kontaminan (topsoil, saprolitedan bedrock) dengan konsentrasi 90:10, 75:25, dan 60:40 berbanding lurus dan selaras dengan pergeseran kadar dari berbagai unsur yaitu Ni, Fe, Co, MgO, Al2O3 dan SiO2, dibandingkan dengan hasil Analisa dari sampel dari zona transisi di pit yang menggambarkan karakteristik dari nikel ore laterit dari zona transisi yang alami di bentang alam yang sebenarnya.

Kajian Teknis Unit Pencucian Bauksit pada Washing Plant untuk Memenuhi Target Produksi di PT Bumi Khatulistiwa Bauksit Kecamatan Meliau Kabupaten Sanggau
type: item
description: PT. Bumi Khatulistiwa Bauksit salah badan usaha yang menjalankan kegiatan disektor pertambangan dengan fokus pada sumber daya bauksit berlokasi dan beroperasi di Kecamatan Meliau, Kabupaten Sanggau, Provinsi Kalimantan Barat. Dengan sistem penambangan terbuka (surface mining). PT. Bumi Khatulistiwa Bauksit menetapkan target sebesar 4.167 ton/hari. Produksi aktual dari perusahaan hanya mencapai 1.852 ton/hari dibulan September 2024, maka produksi belum memenuhi target yang sudah ditetapkan. Hal ini dikarenakan rendahnya efektifitas kerja unit pencucian (hopper, trommol baby, trommol screen). Dan terdapat faktor hambatan yang terjadi, yaitu kerusakan washing plant, gangguan cuaca, hopper kosong, boulder tersangkut, penirisan penuh, keterlambatan alat mulai beroperasi, istirahat lebih awal, istirahat terlalu lama, dan waktu berhenti beroperasi lebih awal. Untuk melakukan upaya peningkatan produksi unit pencucian, maka dilakukan perbaikan mengelola waktu kerja secara optimal dengan mengatasi hambatan yang dapat diminimalkan dengan menghilangkan waktu keterlambatan alat mulai beroperasi, istirahat lebih awal, istirahat terlalu lama, dan berhenti beroperasi lebih awal. Efisiensi kerja meningkat dari yang semula 83,24% menjadi 94,27% namun masih belum bisa mencapai target produksi. Upaya selanjutnya yang dilakukan adalah penambahan ore feeding sebesar 378 ton, peningkatan unit pencucian dari semula hopper : 57,49% menjadi 97,27%, trommol baby : 57,78% menjadi 97,79%, dan trommol screen : 58,24% menjadi 98,56% namun target hanya mencapai 3.134 ton/hari. Upaya terakhir yang dilakukan adalah penambahan waktu lembur yang didapatkan hasil produksi bauksit sebanyak 4.168,31 ton/hari yang artinya mencapai target produksi harian perusahaan

Genetic Analysis of Iron Ore Deposits in Pakke Region Bontocani District Bone Regency South Sulawesi
type: item
description: Characteristics of iron ore deposits vary significantly from the physical properties of the ore carrier rock, the physical and chemical properties of the ore carrier minerals, and the geological conditions of an area, causing variations or types of iron ore deposits. Based on this, the research will focus on the characteristics of alteration or mineral alteration in iron ore deposits in the Pakke area, Bontocani District, and Bone Regency. This study aims to determine the type of alteration in iron ore deposits. The sampling process used chip sampling and grab sampling, where five samples were taken in the form of ore samples. The data analysis process from the samples obtained was analyzed using petrographic analysis, micrography, and XRD (X-ray diffraction). Petrographic analysis is used on altered rock samples to determine alteration mineral assemblages and rock names. Mineragraphic analysis was carried out on iron ore samples to determine the assemblage of iron ore carrier minerals and alteration characterizing ore minerals. XRD (X-ray diffraction) was conducted to determine the set of alteration minerals, iron ore carrier minerals, and alteration-characterizing ore minerals. The characteristic of skarn-type alteration is the type of alteration formed in the research area. Skarn alteration is characterized by the presence of the main characterizing minerals, namely garnet, epidote, diopsid, and wollastonite. The sequence of formation of the alteration of the curvature includes three stages, namely the first isochemical (600ºC), the second stage is metasomatism (600-400ºC), and the third stage is retrograde (400-200ºC).

Studi Penyaliran Tambang Pada Penambangan Batubara Pit B Rawa Selatan Pada Main Sump A4 di PT Mandala Karya Prima Kalimantan Utara
type: item
description: Industri pertambangan batubara merupakan salah satu sektor penting dalam mendukung kebutuhan energi di Indonesia. Namun, aktivitas penambangan batubara seringkali dihadapkan pada berbagai tantangan teknis, salah satunya adalah masalah air tambang. Air yang masuk ke area tambang dapat berasal dari air hujan, air permukaan, atau rembesan air tanah. Keberadaan air tersebut, jika tidak dikelola dengan baik, dapat menyebabkan gangguan operasional, meningkatkan risiko keselamatan, dan merusak lingkungan sekitar. Seiring dengan kemajuan tambang, akan dilakukan penutupan sump yang mengubah luasan tangakapan hujan dan memerlukan perhitungan kembali untuk melakukan rancangan sistem penyaliran tambang. Penelitian ini bertujuan untuk mengetahui proses sistem penyaliran tambang yang dimulai dari perhitungan curah hujan, luasan daerah tangkapan hujan, debit air limpasan, dimensi sump, kebutuhan pompa, dan dimensi saluran terbuka. Perhitungan curah hujan dimulai dari tahun 2014-2023 dan ditentukan dengan menggunakan distribusi log pearson III, didapatkan hasil yaitu 112,36 mm/hari yang diambil dari periode ulang 5 tahun. Berdasarkan hasil penelitian, diperoleh intensitas curah hujan 24,54 mm/jam, koefisien limpasan 0,90 dan daerah tangkapan hujan 3,22 km2 sehingga didapatkan debit limpasan yang masuk pada sump A4 RL-50 adalah 71,173 m3/jam dengan waktu hujan selama 2 jam dan didapatkan volume sump sebesar 407,585 m3. Untuk mengeluarkan air yang ada pada sump A4 RL-50 dibutuhkan 3 unit pompa dan 3 unit booster multiflo 420 EXHV dengan pipa 14 inci atau 355 mm dengan jam kerja pompa selama 20 jam durasi pengeringan selama 4 hari.

Dealuminasi Zeolit Daerah Moncongloe Kabupaten Maros Provinsi Sulawesi Selatan Dengan Menggunakan Asam Sulfat
type: item
description: Zeolite is a hydrated aluminosilicate mineral that possesses pore structures to be used as an absorbent material. These absorbent properties of zeolite are useful in the adsorption of toxic materials such as ammonium and heavy metals. It can therefore be used as additives in livestock, shrimp farming, wastewater treatment, and palm oil refining. However, the commonly used natural zeolite has a low Si/Al ratio and higher impurities. It can therefore reduce the absorption capability. One of the activation methods of zeolite is chemical dealumination; that is removal of Al from crystal structures of zeolite to increase its Si/Al ratio. This research aimed to find out the mineralogical and chemical composition of zeolite samples. Dealumination experiments were then carried out using sulfuric acid as a solvent with acid concentration and temperature as experimental variables. Results of the analysis show that zeolite contains feldspar, clinoptilolite, mordenite, and quartz. The chemical composition of zeolite was dominated by SiO2 and Al2O3. The experiment indicates Si/Al ratio was increased from 1.09 to 1.29, which was achieved at an H2SO4 concentration of 1.5 M with a temperature of 100oC.

Geologi dan Mineralisasi Endapan Emas Orogenik di Gunung Lipan, Kecamatan Rorowatu, Kabupaten Bombana, Sulawesi Tenggara, Indonesia
type: item
description: The prospect of Gunung Lipan is located in Rorowatu District, Bombana Regency, Southeast Sulawesi Province. Physiographically it is situated in the Rumbia mountains, which is occupied by the metamorphic rocks of Pompageo complex. The Gunung Lipan is a prospect which has potential to produce gold mineralization in the Rumbia Mountains. However, a detailed research has never been carried out, in which the latest research is still on regional scale. Therefore, this study aims to understand more details about the geological conditions, alteration types and mineralization characteristics of the prospect and its surroundings. The research methods include geological mapping, petrographic analysis to determine type of hostrock, ore microscopy analysis to determine sulfide minerals in rocks/veins, and ore geochemistry to determine metal content in rocks and veins. Gold mineralization in the Gunung Lipan is hosted by mica schist, and controlled by sinistral shear fault in form of shear zone. The fault movement in the field is indicated by the presence of a milonite structure in the rock and the texture of mica fish on microscopic observations. The hydrothermal alteration appears at the study area is a typical type of alteration found in orogenic gold deposits such as silicification, carbonatization, and carbonization, argillic and propylitic. The sulfide minerals of orogenic type of gold deposit occurred in this study consist of stibnite, cinnabar, tripuhyite, pyrite, arsenopyrite, and hematite. Sulphide minerals are present in rocks and veins in disseminated form. Based on the results of geochemical analysis of gold content ranging from <0.005 ppm to 1.25 ppm, high grade gold was found in quartz veins that cross-cut foliation and veins with brecciated texture. Correlation of metallic elements using multivariate statistical methods shows that gold is positively correlated with As, Sb, and Hg, negatively correlated with Ag, and base metal elements (Pb, Zn, and Cu) are not abun…

Kajian Struktur Geologi Daerah Muaro, Kabupaten Sijunjung, Sumatera Barat
type: item
description: Sumatra has long been recognized as the interacting region between Indo-Asutralian plate and Eurasian plate, hence the tectonic deformation occurring in the island may have affected by the converging movement of these plates. This study focuses on evaluation of the tectonic structures developed in the Muaro region by integrating the field data and the lineament pattern interpreted from Digital Elevation Model (DEM). Study area is situated within the Ombilin basin, known as the intramontane basin that formed due to transtensional movement of the Sumatran fault system. The DEM image used to identify structure is that of DEMNas, which has been extracted on ArcGIS 10.3 and PCI-Geomatica. The results of interpretation reveal that the alignment shows a general orientation northwest-southeast, which is parallel to a structural pattern of the Kabun anticline, the Silokek syncline, and the Kabun fault. The consistency in orientation between the lineament pattern and the structural trend indicates that the direction of tectonic forces responsible for the deformation of rock sequence was likely northwest-southeast.

Identifikasi Struktur Geologi Daerah Sijunjung, Kabupaten Sijunjung, Sumatera Barat
type: item
description: The study area is located in Sijunjung, and tectonically situated in Ombilin basin, which is considered as an intramountain basin or a sedimentary basin within a mountainous range of Bukit Barisan. Geological mapping has been previously carried out, and the present study conducts a structural evaluation by integrating field data and results of interpretation upon lineament using images of Digital Elevation Model (DEM), applying ArcGIS and PCI-Geomatic programs. Results of imagery analysis reveal that the lineament shows a general trend to NW-SE, and this orientation is consistent to that of structures developed in the region studied, especially those of Padangdoto, sesar Aie Angek, dan sesar Takung. The patterns of lineament and structure which are both directed to NW-SE can be interpreted that the region has been controlled by transtensional stresses due likely to the movement of active faults along the Bukit Barisan mountains.

Karakteristik Dan Petrogenesa Batuan Beku Granit Di Daerah Sibayu, Kecamatan Balaesang, Kabupaten Donggala, Provinsi Sulawesi Tengah
type: item
description: The tectonic history of Sulawesi is closely related to the activities of the three major world plates that surround it. This results in the complexity of geological conditions on the island of Sulawesi, including the diversity of rock types. One of the most common types of rock is igneous granite, which is widespread in the Sibayu area, Donggala Regency, Central Sulawesi Province. This study aims to determine the characteristics and petrogenesis of igneous granite using megascopic and microscopic or petrographic observation methods. The results showed that the rock has a megascopic appearance in the form of a grayish-white fresh color and a brownish weathered color, a holocrystalline texture, a massive structure, and a mineral composition consisting of orthoclase, amphibole, and quartz. Its microscopic appearance shows a brownish-transparent color on parallel nikol, on brown cross-linked nikol, light gray to dark gray, mineral size 0.15-0.05 mm, the average mineral composition is orthoclase (41.25% ), quartz (43.75%), biotite (11.25%) and plagioclase (3.75%). Based on these data, it can be concluded that the rocks are Late Miocene to Late Pliocene, which proves that the Palu-Koro fault was still active during the Late Miocene to Late Pliocene. The presence of biotite in granitic rocks characterizes S-Type granite which is formed deep below the earth's surface which is characterized by euhedral-subhedral forms.

Analisis Kestabilan Lereng pada Pit Bengkirai Tambang Terbuka Batubara di PT Guruh Putra Bersama Site Gunung Sari Kecamatan Tabang Kabupaten Kutai Kartanegara Kalimantan Timur
type: item
description: PT Guruh Putra Bersama (GPB) is one of the mining company engaged in coal mining that applies an open pit mining system located at the Gunung Sari Village Site, Tabang District, Kutai Kartanegara Regency, East Kalimantan Province with an IUP area of 3.205 ha. In open pit mining activities, slope stability is a problem that needs to be considered for mining activities that operate every day. The condition of the slope geometry in the pit design with the actual conditions in the field is also a problem of slope stability. A safe and stable mine slope will ensure the smooth operation of mining operations, therefore it is necessary to analyze slope stability and optimal mine slope design to support a better process of mining operations. This research was conducted in the Bengkirai pit using geotechnical drill data GPBF-03 at PT Guruh Putra Bersama (GPB). Slope stability conditions at PT Guruh Putra Bersama (GPB) based on the results of slope stability analysis in the Bengkirai pit is a stable or safe slope because the FK value > 1,3. The single slope on the dumping road area has an FK value of 3,193 with a slope height of 8,6 meters and a slope angle of 51,36o. The overall slope of the Mine Situation Map and Pit Design has FK values of 3,992 and 3,286, respectively. The FK value on the overall slope has a difference of 0,706 because the two overall slope geometries are different both in height and slope angle. However, because both of the overall slopes have a value of FK> 1,3, the slope is stable and the slope geometry on the mine situation map does not need to change its dimensions.

Determination of Relative Error in Coal Resource Classification Based On Geostatistical Drill Hole Spacing Analysis: A Case Study of Coal Deposits at Batang Hari, Jambi
type: item
description: Generally, the determination of resource classification is only qualitative based on the geometric factors and geological complexity that control it. However, as the prospect area is found to have a reasonably heterogeneous sediment characteristic, a method is needed that can be used to increase the level of confidence in determining the Optimum Drill Hole Spacing. Therefore, this study uses the application of geostatistics with the Global Estimation Variance (GEV) method based on the relative error value of each parameter, namely the thickness geometry and quality in the form of Ash and VM. This research was carried out in Jangga Aur village, Bathin XXIV District, Batang Hari Regency, Jambi Province, Working Area of PT Berkat Bara Persada Jobsite PT Inti Bara Nusalima.The Drill Hole Spacing Analysis (DHSA) results will obtain optimum spacing on resource classification based on relative error values, namely 0 to 10% for measured resources, 10 to 20% for indicated resources, and > 20% for Inferred resources carried out the on-seam reference. Based on the results of the study, it was found that the seam reference used was Seam D, then the spacing distance of the drill hole on the coal seam of the research area, which had an average distance of 80 m, with geostatic analysis could be increased up to a distance of 250 m in measured resources, indicated resources of 450 m and inferred 800 m.
