Tanamerah Village is one of fourteen villages in Saronggi District, Sumenep Regency, East Java. Villagers experience water difficulties during both the rainy season and the dry season. Technical guidance will be carried out for groundwater identification to find out where the groundwater points are located that are able to meet the community's water needs. The method used for identification makes six tracks with varying distances between tracks. The length of each passage is twelve meters, and the depth of each passage is three hundred meters. Identification was carried out on village treasury land with an area of 500 m2. Six tracks in this service, the distance between tracks is 5-8 m, and the length of each track is 12 m. Track 1 was obtained from groundwater at a depth of 80m, and track 2 was obtained from groundwater at a depth of 80 m. Track 3 was obtained from groundwater at a depth of 70 m, and track 4 was obtained from groundwater at a depth of 20 m. Passage 5 is obtained from groundwater at a depth of 20 m, and passage 6 is obtained from groundwater at a depth of 70 m. Recommended drilling point is located on the TM1 line at point 8 with a depth of 80 m.

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.

This study focuses on the evaluation of the production capacity of loading and hauling equipment in limestone mining operations at PT. X, South Sulawesi Province. The selection of this topic is based on the importance of operational efficiency in limestone mining which has a direct impact on the productivity and sustainability of the cement industry. The main objectives of this study are to determine the actual production of loading and hauling equipment, determine the number of equipment needed to meet production targets and identify compatibility factors between mechanical equipment at the mining site. The methods used include field data collection involving measurement of cycle time and production capacity of loading and hauling equipment. The data obtained are then processed using statistical methods to ensure the accuracy of the results. Data analysis is carried out by considering variables such as work efficiency, cycle time, and equipment capacity. The results show that Kobelco SK 480 LC has the highest production capacity (509.34 tons/hour), followed by Komatsu PC 400 (448.25 tons/hour) and PC 300 (417.05 tons/hour). To achieve the Crusher production target of 1450 tons/hour, a combination of loading equipment and dump trucks with a compatibility factor between 0.87 and 0.92 is required, indicating potential for increased efficiency. It is recommended to improve maintenance of equipment and mining roads to optimize productivity.

Kualitas air bersih merupakan faktor penting dalam mendukung kesehatan masyarakat, terutama di kawasan perumahan padat penduduk. Penelitian dan program ini bertujuan untuk menguji serta meningkatkan kualitas air bor di Kelurahan Sidorahayu, Kecamatan Wagir, Kabupaten Malang, guna memastikan kesesuaiannya dengan standar baku mutu air untuk keperluan higiene dan sanitasi. Kegiatan dilakukan melalui tiga tahapan utama, yaitu persiapan, pelaksanaan, dan evaluasi. Pengujian air dilakukan pada beberapa titik sumur bor yang dipilih secara representatif dengan parameter meliputi pH, Total Dissolved Solids (TDS), konduktivitas, Oxidation Reduction Potential (ORP), dan suhu, kemudian dibandingkan dengan ketentuan Permenkes No. 2 Tahun 2023. Hasil menunjukkan nilai pH 8,19–8,25 masih dalam batas aman meskipun cenderung basa, TDS 119–137 ppm, dan konduktivitas 114–131 µS/cm yang menandakan kualitas air relatif baik untuk keperluan nonkonsumsi. Namun, nilai ORP negatif menunjukkan kondisi reduktif yang berpotensi memengaruhi aspek mikrobiologis, sehingga diperlukan uji lanjutan terhadap Escherichia coli dan Total Coliform. Berdasarkan hasil tersebut, direkomendasikan langkah teknis seperti pemasangan filter sederhana, perebusan air, serta peningkatan kesadaran masyarakat terhadap kebersihan lingkungan dan pengelolaan limbah. Program ini menunjukkan bahwa kolaborasi antara masyarakat, perguruan tinggi, dan pemerintah daerah mampu mendukung pengelolaan air bersih yang berkelanjutan.

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

Unmanned Aerial Vehicle (UAV) photogrammetry has gained significant popularity across various industries due to its versatility in a wide range of applications. In the field of surveying, UAV photogrammetry offers a faster and more cost-effective solution compared to surveying conventional methods such as leveling instruments or total stations. In rural areas, the pavement of village access roads is vulnerable to deterioration, particularly in the form of settlement caused by repeated loads from transport vehicles. Therefore, monitoring pavement settlement is essential to ensure safety and facilitate timely maintenance planning. Mostly, pavement settlement measurements are conducted using conventional surveying methods. This study aims to explore the potential of UAV-photogrammetry in monitoring pavement elevation in rural areas and to assess its accuracy compared to conventional surveying methods. Aerial data acquisition was conducted in two separate epochs: Epoch I on December 18, 2024, and Epoch II on April 23, 2025. These multitemporal aerial surveys produced a series of overlapping aerial photos. Within the study area, point markers were installed as reference points for elevation measurements on the generated Digital Elevation Model (DEM). The elevation change from Epoch I to Epoch II ranged from 0.00 to 0.029 meters. However, this change cannot be directly interpreted as pavement deformation or settlement. This limitation arises because the root mean square error (RMSE) values of the elevation data obtained from UAV photogrammetry and total station measurements range from 0.048 to 0.098 meters.
