Limestone mining is a quarry system mining . Its production is influenced by weather factors, especially rainfall. This study aimed at determining the mathematical model wich is able to correlate the influence of rainfall on production of limestone. In addition, it analyzed the correlation between rainfall and limestone production using linear regression method. There are four important steps in this research. The first step is to collect data production and production factors. The second step is to process the data into a mathematical model using linear regression. The third step is to test the result of the mathematical model with the statistical test method. Then the fourth step is to analyze the mathematical model that has met the statistical test results. The results showed that the best mathematical model was: Log P = 0.502 x LOG((JO X Pr) 1.99 x (CH)-0.001) + 0.0002. In conclusion, the effect of rainfall toward the production derivation was very low. Besides, operation hours and productivity also affected production derivation.

At the end of mining, an open pit coal mine will form a mine sump, also known as a “pit lake”. At PT ABC, the pit wall rock lithology consists of 30% potentially acidic rock and 70% non-acidic rock, with low pH sump water quality. The static test is intended to calculate the balance of acid-forming and acid-consuming components. The static test does not consider the rate of acid formation and neutralization. The objective is to determine the potential for acid formation to occur in the rock. The kinetic test aims to understand the kinetics of acid formation reactions in samples through a simulation of oxidation reactions in rocks. This test can predict long-term weathering characteristics as a function of time. Of the 4 rock samples tested statically, all samples showed PAF (Potencial Acid Forming) screening criteria. The results of the kinetic test showed that sample S1 experienced an increase in pH to 4,43, sample S2 experienced a decrease in pH to 8,03, sample S3 experienced an increase in pH to 2,44, and sample S4 experienced an increase to 7,24.

Indonesia adalah negara dengan potensi sumberdaya mineral yang melimpah, menjadikan sektor pertambangan sebagai salah satu pilar utama perekonomian nasional. Akan tetapi, beberapa kegiatan pertambangan masih memiliki nilai ekonomi rendah karena gagal memenuhi standar teknis dan kriteria kelayakan pertambangan. Oleh karena itu, kegiatan eksplorasi diperlukan untuk menentukan potensi sumberdaya secara lebih akurat. Penelitian ini bertujuan untuk menganalisis distribusi dan mengestimasi sumberdaya tanah urug di Desa Toyomarto, Kecamatan Singosari, Kabupaten Malang, Provinsi Jawa Timur, dengan luas area penelitian 2,7 hektar. Metode penelitian yang digunakan meliputi pengumpulan data melalui observasi lapangan dan studi literatur, analisis data spasial, pembuatan peta topografi, dan perhitungan volume tanah urug menggunakan perangkat lunak pertambangan. Proses estimasi sumberdaya dilakukan menggunakan metode Inverse Distance Weighting (IDW) dengan beberapa variasi parameter pangkat untuk mendapatkan hasil interpolasi yang paling akurat. Hasil analisis menunjukkan bahwa nilai Mean Absolute Percentage Error (MAPE) terkecil diperoleh pada parameter power 3, dengan nilai prediksi 47,32 dan tingkat kesalahan minimum 1,06%. Berdasarkan perhitungan ini, estimasi volume sumberdaya tanah urug di lokasi penelitian diperkirakan mencapai 258.912 m³. Hasil penelitian ini diharapkan dapat memberikan dasar untuk perencanaan kegiatan penambangan tanah urug yang lebih optimal dan mendukung pengelolaan sumberdaya mineral yang efisien dan berkelanjutan.

Penilaian risiko geoteknik ini menginvestigasi kerentanan likuefaksi pada lokasi kritis Jembatan Jurug di Surakarta, sebuah wilayah yang diklasifikasikan sebagai Kelas Situs SE (Tanah Lunak) dengan potensi seismik tinggi yang dipengaruhi oleh Sesar Kendeng. Lapisan bawah permukaan dicirikan oleh endapan aluvial muda berupa pasir halus dan lanau berpasir dengan kepadatan rendah hingga sedang, serta muka air tanah yang dangkal (2 hingga 6 m). Analisis menggunakan metode semi-empiris Seed et al. (1985) dengan nilai N-SPT terkoreksi (N160) untuk menghitung Faktor Keamanan (FS) dan Indeks Potensi Likuefaksi (LPI) hingga kedalaman 20 m guna mengukur tingkat keparahan manifestasi permukaan. Hasil menunjukkan variasi spasial kerentanan yang signifikan: Titik Bor 02 (BH-02) merupakan zona paling kritis dengan potensi likuefaksi tertinggi, ditunjukkan oleh nilai FS terendah dan LPI tertinggi, yang terkonsentrasi pada lapisan dangkal hingga menengah (0 hingga 18 m) di mana FS<1 terjadi secara konsisten. Sebaliknya, BH-01, BH-04, dan BH-05 menunjukkan potensi likuefaksi sedang yang terpusat pada lapisan permukaan (0 hingga 10 m), sementara BH-03 merupakan area paling stabil dengan FS tinggi dan LPI rendah yang konsisten. Hal ini mengharuskan adanya mitigasi geoteknik mendesak pada zona dangkal berisiko tinggi, seperti teknik pemadatan (compaction grouting/vibro compaction) atau metode berbasis drainase (PVD), guna memastikan integritas struktural jembatan terhadap pembebanan seismic.

Coal still plays a major role in Indonesia's energy mix, accounting for approximately 40% of the national primary energy mix in 2024., while low-emission technologies are becoming dominant in the world. In this study, a Systematic Literature Review (SLR) was performed to conduct an evaluation of technological developments and implementation challenges on the clean coal utilization which include gasification, clean combustion systems, activated carbon production and valorization of coal residues (fly ash and bottom ash) from both international view as well as Indonesian perspective. All international and national peer-reviewed articles (published between 2014–2024) were reviewed to analyze trends, gaps, and technical readiness. It is found that coal gasification technology provides the highest energy conversion efficiency of up to nearly 75%, and can cut carbon emissions by 40–60% in comparison to traditional combustion. On the other hand, fly ash and bottom ash utilization of for example 20 million tonnes per year could save up to around Indonesia’s coal power waste generation as well as support circular economy goals. There are still barriers to the adoption of this technology such as high investment costs ($1.2–1.5 million/MW), medium moisture in low rank coal (>30%) and small-scale pilot projects at industrial level. Lessons learnt This article reiterates that R&D needs the backing of fiscal incentives, demo plants and regulatory frameworks to hasten the sustainable deployment of CCTs in Indonesia
