Abstract

This research aimed to determine the influence of side-slip velocity on subsurface displacement during seismic data acquisition. Anisotropy constants were used to determine the depth migration process before stack, which showed inadequate results after data validation. Therefore, the forward modeling of a medium, which comprised anisotropy constants of normal and offset raytracing was conducted to address this problem. The configuration of source to receiver were orthogonal and slant. The results showed that the migration process failed to resolve the geological structures of the position shifting. The configuration of source to receiver were orthogonal and slant. The results show the better continuity of slant and the influence of complex geological structures controls the position shifting, which could not be resolved by the migration process. It could be seen from the random distribution of the normal shift of group velocity and phase velocity, as well as the CDP – CRP shift. It produced wave azimuth rotation in a discontinuity plane, such as fault and anticline ridge. This azimuth rotation was strongly suspected to cause inaccurate anisotropy constants implementation in pre-stack depth migration process. Keywords: side-slip velocity, anisotropy constants, migration, normal displacement, CDP-CRP displacement

Abstract

Tambang Big Gossan di Papua Tengah dikenal dengan mineralisasi tembaga yang terbentuk akibat intrusi diorit pada batuan karbonatan Formasi Waripi. Penelitian ini bertujuan menganalisis karakteristik alterasi dan mineralisasi tembaga di level 2860, 2900, dan 2940 Footwall West. Metode yang digunakan termasuk pemetaan geologi dan analisis laboratorium (petrografi, mineragrafi, dan XRD). Hasilnya, ditemukan empat satuan litologi serta lima zona alterasi, yaitu klinopiroksen-garnet-kuarsa, epidot-klorit-kuarsa-kalsit, garnet-kuarsa-kalsit-piro pilit-epidot, piropilit-kuarsa-kalsit, dan aktinolit-kuarsa-klorit. Mineral sulfida tembaga utama adalah kalkopirit dan bornit, dengan pirit, pyrrhotite, dan magnetit sebagai mineral pembawa besi. Tembaga terakumulasi pada zona retrograde alterasi 2, 3, 4, dan 5. The Big Gossan mine in Central Papua is known for its copper mineralization, formed due to diorite intrusion into the carbonate rocks of the Waripi Formation. This study aims to analyze the characteristics of alteration and copper mineralization at levels 2860, 2900, and 2940 Footwall West. The methods used include geological mapping and laboratory analyses (petrography, mineragraphy, and XRD). The results revealed four lithological units and five alteration zones: clinopyroxene-garnet-quartz, epidote-chlorite-quartz-calcite, garnet-quartz-calcite-pyrophyllite-epidote, pyrophyllite-quartz-calcite, and actinolite-quartz-chlorite. The main copper sulfide minerals are chalcopyrite and bornite, with pyrite, pyrrhotite, and magnetite as iron-bearing minerals. Copper is concentrated in the retrograde alteration zones 2, 3, 4, and 5.

Abstract

Kegiatan penyediaan air bersih merupakan salah satu kebutuhan pokok bagi masyarakat, mengingat air bersih adalah faktor penting dalam kehidupan dan kesehatan masyarakat. Semakin bertambahnya populasi penduduk ditunjang dengan aktifitas ekonomi yang semakin kompleks, juga berdampak pada strategi pelayanan kebutuhan akan air bersih dan pemaksimalan usaha untuk menghadirkan sarana air bersih. Masalah air bersih tidak hanya hadir di daerah-daerah terpencil yang belum tersentuh pembangunan, daerah perkotaan dengan jaringan infrastruktur PAM yang sudah memadai pun terkadang masih terkendala dengan aktifitas pencemaran air dan penggunaan air berlebihan yang tidak efektif dan efisien. Desa Sungai Dayo, Kecamatan Bahar Utara, Kabupaten Muaro Jambi, memiliki permasalahan air yang kotor dengan kandungan mangan dan besi yang tinggi. Selain tercemar limbah, hasil penelitian menunjukkan bahwa air tanah di daerah tersebut bersifat payau dan mengandung pengotor unsur mangan, besi, dan fluoride tinggi yang tidak baik untuk kesehatan, terutama kesehatan gigi. Berkaitan dengan hal tersebut kegiatan PkM ini menawarkan solusi alternatif yang bisa dipakai masyarakat dalam menyelesaikan permasalahan air bersih yaitu dengan menggunakan rekayasa material mineral lempung bentonit dalam pembuatan filtrasi air.

Abstract

Mineral and coal mining has a significant impact on the surrounding environment. One of these impacts is the formation of post-mining lakes, often referred to as mine voids or pit lakes. The unavailability of rocks or the lack of cover material to backfill the mining area forms post-mining lakes. A post-mining lake forms when water fills the mine hole. In rock mining with the quarry method that reaches a certain depth, post-mining lakes are often formed because all the rocks are taken as products, so that no cover rock remains. The existence of post-mining lakes in several areas can have both positive and negative impacts. The positive impact is the sustainable use of post-mining lakes, for example, as a water resource for the surrounding community. Given the important role of post-mining lakes, it is necessary to conduct socialization with the community about how to utilize them. One area that requires attention is the Rumpin area, Bogor Regency, West Java, which has many post-mining lakes. We expect the community to gain insight and input regarding the potential utilization of water from post-mining lakes through this socialization activity. Thus, we can achieve the goal of sustainable mining while directly benefiting the surrounding community.

Abstract

Slag waste from the metal refining industry, if left to accumulate for a long time, can become a source of environmental pollution due to the content of heavy metals that can dissolve and spread to the surrounding environment. However, slag can also be an alternative source for obtaining valuable metals. Aim: This study aims to examine the ability of diethylaminedithiocarbamate ligands to recover nickel metal from slag waste through the mechanism of complex compound formation. Methodology and results: The extraction process was carried out at the optimal pH for each ligand to maximize the selectivity and efficiency of metal recovery. Characterization of the complex compounds from the reaction was carried out using various analytical techniques, including Fourier Transform Infrared Spectroscopy (FTIR), UV-visible spectroscopy (UV-Vis), X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS), and melting point tests to determine the thermal stability of the compound. The study results indicate that diethylaminedithiocarbamate ligands can selectively form complex compounds with nickel metal in slag and are effective in recovering metals from slag waste with a recovery value of 94.88%. Conclusion, significance, and impact study: The results of this study indicate that using diethylaminedithiocarbamate ligands can be an environmentally friendly approach to using slag waste as a secondary source of metals.
