Abstract

Pemodelan sumber daya batubara seam tegak Formasi Warukin di daerah Kecamatan Barito Tuhup Raya, Kalimantan Tengah, sering terdistorsi jika ketebalan tampak dihitung tanpa koreksi inklinasi borehole. Penelitian ini mengevaluasi dampak integrasi inklinasi pada estimasi total sumber daya batubara di wilayah IUP PT X. Data eksplorasi terdahulu, yang tidak memperhitungkan inklinasi, diolah ulang dengan memasukkan sudut inklinasi ke dalam pemodelan tiga dimensi menggunakan aplikasi Minescape 2023 (modul Stratmodel). Hasil menunjukkan peningkatan koefisien determinasi (R²) dari 0,0225 menjadi 0,039 setelah inklinasi diterapkan, menandakan akurasi yang lebih tinggi antara ketebalan model dan observasi lapangan. Estimasi total sumber daya juga turun dari 6.091.300 ton (tanpa inklinasi) menjadi 5.660.486,98 ton (dengan inklinasi), mengindikasikan over estimasi sekitar 7,1% jika inklinasi diabaikan. Perbedaan paling besar terjadi pada kategori “Terkira” dengan selisih mencapai 49,5%. Temuan ini menegaskan bahwa koreksi true thickness melalui inklinasi borehole wajib diterapkan dalam eksplorasi seam tegak guna menghasilkan estimasi sumber daya yang lebih realistis dan mengurangi risiko perencanaan tambang yang terlalu optimistis.

Abstract

Eksplorasi lanjutan tambang batugamping merupakan bagian integral dari strategi pengelolaan sumber daya mineral yang berkelanjutan, khususnya dalam konteks industri semen dan bahan bangunan. Kegiatan ini tidak hanya bertujuan untuk memperkuat basis data geologi dan mengidentifikasi cadangan baru, tetapi juga mendukung pengambilan keputusan strategis bagi keberlanjutan operasi jangka panjang. Melalui pendekatan multidisipliner, kajian ini menelaah berbagai aspek eksplorasi lanjutan, mulai dari karakterisasi geologi regional dan lokal, perencanaan teknis eksplorasi, hingga evaluasi keekonomian berdasarkan model sumber daya dan biaya kegiatan eksplorasi. Aspek manajemen risiko dan kepatuhan terhadap regulasi nasional—seperti UU No. 3 Tahun 2020 tentang Pertambangan Mineral dan Batubara serta kebijakan perizinan IUP—juga menjadi sorotan utama. Selain itu, eksplorasi yang berwawasan lingkungan menuntut integrasi prinsip Environmental and Social Governance (ESG) sebagai bagian dari tata kelola perusahaan yang bertanggung jawab. Studi kasus difokuskan pada wilayah eksplorasi di Zona Kendeng, Rembang, Jawa Tengah, yang memiliki potensi batugamping signifikan dan tantangan geologi kompleks. Dengan menggabungkan data primer dan sekunder serta mengacu pada literatur ilmiah dan kebijakan pemerintah, makalah ini menyusun rekomendasi strategis yang aplikatif bagi pengelolaan eksplorasi lanjutan. Rekomendasi tersebut diharapkan mendukung efisiensi operasional, mitigasi risiko lingkungan, serta pencapaian tujuan keberlanjutan industri.

Abstract

Eco enzyme is a product of organic waste derived from vegetables and fruits, fermented with sugar in a container and allowed to stand for three months to become an active solution. The use of eco-enzyme as a natural cleaning solution contributes to protecting the environment because it treats household-scale organic waste. The community service program aims to enhance Cigombong Village's potential with a community that cares about the environment that has been formed. The eco enzyme can be used to clean all areas of the house, clothes, vegetables, and fruits, fertilize plants, eliminate pests, and improve the quality of plants; the eco enzyme is also very effective in repelling plant pests. The eco enzyme can also be utilized to stimulate plant hormones to enhance fruit and vegetable quality and improve crop yields. Making eco enzymes can be done simply, using easily available equipment. The raw materials for eco enzyme consist of brown sugar, water, and fruit peel waste in a ratio of 1:10:3. The container used for the eco enzyme is a plastic jar with a lid. A training program for making eco enzymes from fruit and vegetable peel waste can protect the environment, increase community plantation yields and make Cigombong village a fruit tourism village.

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

Abstract

Uncertainty is often present in the relationship between physical property variables and the complexity increases, when mechanical properties are included. The problems becomes more interesting in cases, where fluid dynamics act as the primary contributing factor. Pore pressure changes is the main actor of every uncertainty of physical properties. Therefore, this study aimed to examine the influence of fluid dynamics on physical uncertainties of hydrocarbon reservoir. To achieve this objective, well data from production and enhanced oil recovery (EOR) operations between 1994 to 2007 were entangled. Specifically, 3D seismic data was incorporated to distribute physical and mechanical properties after well periodization. In this study, the impact of pore pressure changes on minimum horizontal stress from 1994-2017 was also examined. The results showed that changes in porosity were not significant, but variations in bulk modulus and Poisson's ratio remained observable. Furthermore, tensors field were not dominated by vertical stress, instead of horizontal stresses. Changes in pore pressure apparently had a significant impact on minimum horizontal stress. The increase of  minimum horizontal stress reached approximately one third of pore pressure change. Consequently, the stress regime transitioned from the strike-slip fault in 1994 to thrust fault in 2017, emphasizing a significant increase in the influence of horizontal stress. While water injection and oil production did not lead to significant changes in physical properties, the effects were evident in the variations of Poisson's ratio.
