Abstract

Abstrak: Biologi merupakan pelajaran IPA yang mempelajari kehidupan organisme, termasuk struktur, fungsi dan pertumbuhannya. Pembelajaran biologi perlu menambahkan keterampilan menggunakan alat peraga atau praktikum seperti pengamatan bentuk sel, ukuran sel, serta pergerakan mikroorganisme. Oleh karena itu perlu adanya sarana berupa mikroskop. Keterbatasan ketersedian mikroskop yang dimiliki sekolah mengakibatkan guru kurang optimal dalam melakukan penelitian dan pengajaran. Oleh karena itu perlu adanya optimalisasi kinerja mikroskop dengan cara mengubah mikroskop konvensional menjadi digital. Berdasarkan permasalahan tersebut, maka diadakan pelatihan Optimalisasi Mikroskop konvensional menjadi digital bagi guru biologi. Pelatihan mulai dengan pengenalan fungsi masing-masing komponen alat tambahan seperti kamera, lampu, dan perangkat lunak penangkap gambar. Selanjutnya dilakukan pelatihan instalasi dan mengoperasikan perangkat lunak penangkap gambar serta pengamatan menggunakan mikroskop digital. Pelatihan terakhir yaitu analisis gambar yang diperoleh dari mikroskop digital menggunakan perangkat lunak Image J. Hasil evaluasi menunjukkan bahwa 4 guru biologi sudah mampu mencapai level 3 yang artinya guru menguasai penggunaan mikroskop digital, penggunaan perangkat lunak serta melakukan analisis gambar menggunakan Image J. Tingkat pemahaman guru menggunakan mikroskop digital mencapai 90%. Abstract: Biology is a science lesson that studies the life of organisms, including their structure, function and growth. Biology learning needs to add skills using teaching aids or practical such as observing cell shape, cell size, and the movement of microorganisms. Therefore, it is necessary to have a tool in the form of a microscope. The limited availability of microscopes owned by schools causes teachers to be less than optimal in conducting research and teaching. Therefore, it is necessary to optimize the performance of the microscope by converting conventional microscopes to digital ones. Based on these problems, a training on Optimization of Conventional Microscopes to be Digital was held for biology teachers. The training begins with an introduction to the function of each component of the auxiliary equipment such as cameras, lights, and image capture software. Furthermore, training on the installation and operation of image capture software and observations using a digital microscope was carried out. The last training was analysis of images obtained from digital microscopes using Image J software. The evaluation results show that 4 biology teachers have been able to reach level 3, which means that teachers able to use of digital microscopes, use software and image analysis using Image J. The level of understanding of teachers using digital microscopes reaches 90%

Abstract

The research sites are located in the village of Berambang, Sekotong District, West Lombok Regency,West Nusa Tenggara Province. This area was dominated by volcanic rocks composed of dasiticvolcanic rock, diatrema breccia, and diorite intrusion. Berambang area shows alteration in the form ofpotassic, propylitic, advanced argillic, and argillic alterations where in some places accompanied bypyritisation and stockwork structure, the type of mineralization in this area is a porphyry copper-goldtype. In the potasic alteration zone there are minerals that have a strong anomaly response to themagnetic due to the presence of oxide minerals magnetite (Fe2O3). Mineral sulfides such as pyrite(FeS2) and chalcopyrite (CuFeS2) will also provide significant anomalous responses that have anabundance of 2-5% in the potassic zone. In a propylitic alteration zone characterized by chlorite,calcite and epidote minerals that do not respond to magnetic anomalies, the presence of pyriteminerals, hematites and chalcopyrite with abundance of ≤1% will provide some magnetic anomaly inthe propylitic zone. As for advanceargillic alteration zones characterized by mineral andalusite, aluniteand quartz, there will not be any magnetic anomalies, the phenomena was due to the rarity ofmineralization in this zone gives an insignificant anomalous impact. Meanwhile, for the argillic zonecharacterized by mineral illite, kaolinite and smectite will not have anomalous magnetic impact, veryrare mineralization in the argillic zone so that the magnetic anomaly is not significant. From the floatingEuler 3D shows an anomalous source from a depth of 0 meters to a depth of more than 400 meters.

Abstract

Nikel laterit adalah proses oksidasi atau pelapukan batuan ultramafik pembawa Ni-Silikat umunya di daerah sub tropis-tropis. Penelitian ini bertujuan untuk mengetahui pengaruh morfologi terhadap ketebalan dan zona pengkayaan endapan nikel laterit. Metode penelitian mencakup studi literatur; Mengamati morfologi dan mengumpulkan sampel bawah perkmukaan; analisis laboratorium menggunakan fluoresensi sinar X (XRF); dan analisis data. Hasil penelitian menjelaskan morfologi pada lokasi penelitian termasuk perbukitan rendah/perbukitan memiliki slope agak landai-landai dengan ketebalan lapisan ore yang relatif tebal yaitu 10-13 meter dan slope agak curam-curam ketebalan lapisan ore relatif tipis yaitu 5-12 meter. Distribusi kandungan unusr Fe dan Ni meningkat pada morfologi perbukitan rendah/perbukitan dengan slope yang agak landai-agak curam dengan rata-rata unsur Fe 41.1-31.1% dan unsur Ni dengan rata-rata 1.4-1.3% sedangkan slope yang curam unsur Ni rendah dengan rata-rata 1.1% dimana morfologi mempunyai peran/pengaruh terhadap pelapukan dan pengayaan supergene enrichment sehingga air tanah yang mengandung nikel masuk melalui rekahan/celah batuan dan membawa unsur nikel turun ke lapisan saprolit, karena disebabkan unsur Ni sifatnya mobile/mudah larut terbawa oleh air. Sementara unsur Fe terjadi proses pengayaan di lapisan limonit disebabkan unsur Fe sifatnya immobile atau tidak dapat terbawa atau larut oleh air.

Abstract

The aim of this study is to identify the groundwater aquifer layer using the resistivity method in Puaringan, Pelangan Village, West Lombok. The aquifer layer is a layer of rock that has the ability to store groundwater well. This layer also tends to have high porosity so that fluid/water is trapped in the layer. The resistivity method used is vertical electric sounding (VES). This method is effective in detecting the subsurface vertically. Data acquisition was carried out using two sounding points (S1 and S2). Sounding points S1 and S2 were processed using IP2WIN software to produce a picture of the subsurface rock layer. The results of the S1 point study showed that the groundwater aquifer layer was at a depth of 113-126 meters identified as a sandstone layer. The results of the S2 point study showed that the groundwater aquifer layer was at a depth of 105-198 meters identified as a sandstone layer.

Abstract

The Batu Hijau mine, an extensive copper-gold operation in West Sumbawa, Indonesia, employs an open-pit mining method and is characterized by its significant pit dimensions, with planned slope heights reaching up to 1000 meters. Given the scale of the operation, maintaining slope stability is critical, influenced by stress on the pit slopes, geological structures, mine geometry, and rock mass strength. This study investigates the impact of groundwater on slope stability, emphasizing the role of groundwater pressure in reducing shear strength and consequently affecting slope stability. A comprehensive sensitivity analysis was conducted to evaluate the influence of groundwater pressures on the stability of the Batu Hijau pit walls. This analysis utilized the SLIDE® software from Rocsience, incorporating Rock Mass Rating parameters derived from geotechnical drill hole logs and mapping data, which were integrated into a 3D block model using Minesight™. The analysis focused on two groundwater conditions: Water Surface and Pore Pressure Grid. Groundwater model conditions were based on piezometer data and a new groundwater conceptual model of the Batu Hijau pit walls. Results from sensitivity assessments shows that high pore pressure will decease the slope stability. This findings highlight the need to manage groundwater pressures within the pit walls to mitigate slope instability effectively,therefore, the safety of mining operational could be increased. This study provides valuable insights into groundwater pressure management and its implications for slope stability in large-scale open-pit mining operations.
