Abstract

Groundwater is the primary source of freshwater for communities in Soe Regency, located in the highland of West Timor Island, where surface water resources are limited. This study aims to characterize the groundwater system and assess its sustainability through an integrated approach combining geological mapping, hydrogeological observations, pumping tests, and hydrochemical analyses. Geological mapping identified two dominant lithological units: Quaternary coral limestone, functioning as the main aquifer, and the underlying Noele Formation, where marl layers act as an impermeable base. Hydrogeological surveys revealed four types of spring settings—rock unit contact, fracture-controlled, perched aquifer, and gravel contact springs—demonstrating the role of both karstification and structural controls in groundwater discharge. Groundwater level measurements show that recharge occurs in the northern highlands (elevations up to 1050 m), with flow directed southward and westward towards the Noelmina River. Pumping test results indicate discharge rates ranging from 1 to 11 L/s, with higher productivity in the southern areas. Hydrochemical analysis of 41 water samples shows TDS values of 261–500 mg/L, electrical conductivity of 400–1000 nS/cm (with a localized anomaly of 1200 nS/cm in Hane Village), and pH values of 6.6–8.5, all within safe standards for human consumption.Based on these findings, the Soe groundwater basin is classified into three aquifer productivity zones: moderate, low, and rare. The system is dominated by shallow unconfined aquifers, which remain sufficient in both quality and yield for current needs. However, population growth and urban development pose risks to long-term availability. Therefore, conservation of the northern recharge area is essential, alongside regulation of groundwater abstraction, infrastructure improvements, and exploration of deeper confined aquifers to secure future water resources. This study contributes a comprehensive framework for groundwater system characterization in structurally complex karst environments, providing critical guidance for sustainable water management in semi-arid highland regions.

Abstract

This study examines the relationship between facies and stylolitization in the Upper Araej Member carbonates of onshore Abu Dhabi. Analysis of core and thin sections identified four facies: wispy-laminated skeletal wackestone (F-1), peloidal skeletal mud-dominated packstone (F-2), coated-grain skeletal grainstone (F-3), and peloidal skeletal floatstone (F-4), deposited across a shallow carbonate ramp. Stylolites were described and measured for vertical offset amplitude to assess facies dependence. Results show facies-related tendencies in stylolite amplitude and morphology. Mud-supported facies (especially floatstones and wackestones) tend to display higher variability, with floatstones reaching amplitudes of up to 20 mm, whereas grainstones may also contain isolated high-amplitude stylolites (up to 14 mm). Packstones and wackestones, by contrast, rarely exceed 10-13 mm. Boxplots highlight greater variability in mud-rich facies, whereas grainstones exhibit narrower distributions. Statistical testing (ANOVA, p = 0.109; Kruskal–Wallis, H = 3.38, p = 0.34) indicates no statistically significant differences in mean stylolite amplitude across facies, although descriptive data reveal trends in variability and extremity. Jagged stylolites occur in both mud-rich and grain-supported facies, whereas wispy seams are strongly associated with micrite-rich facies and are largely absent in grainstones. Stylolites in these carbonates may act as both vertical barriers and localized porosity enhancers. Their facies-associated occurrence emphasizes the need to integrate stylolitization into reservoir models to better predict connectivity, compartmentalization, and flow behavior in Middle Jurassic carbonates.

Abstract

Implementation of occupational safety and health is one part of the workforce protection aspect to achieve optimal work productivity. In connection with the implementation of occupational safety and health, the use of Personal Protective Equipment is an effort to protect or prevent potential dangers or work accidents. To describe the relationship between the implementation of CCTV-based monitoring and compliance with the use of Personal Protective Equipment among Jakarta Propertindo Lintas Velodrome - Manggarai LRT project workers in 2024. This research uses a correlative descriptive quantitative research design with the approach used is a Cross Sectional Study conducted on 30 Technician Employees at the Jakarta Propertindo Lintas Veledrome – Manggarai LRT project. The results in this research i statistical results using chi square obtained a P-Value = 0.019 with a degree of confidence or ɑ of 5% (0.05), because the P-Value is 0.019 ɑ value (0.05) meaning that Ho is rejected so it can be It is concluded that this means Ha is accepted or there is a relationship between the Implementation of a CCTV-Based Monitoring System and Compliance with the Use of PPE at the LRT Jakarta Propertindo Lintas Veledrome - Manggarai KSO Project Location of PT Len Railways Systems.

Hydrothermal Alteration and Mineralization in the Grindulu River Segment, Pacitan, East Java: A Study of the Geotourism Potential of the River Area Mineralization Kurniawan, Oki; Purwanto, Heru Sigit; Harjanto, Agus; Winarno, Edy; Fatchurohman, Dedi; Pratomo, Septyo Uji

Abstract

The Grindulu River in Pacitan is one of the areas that exhibits manifestations of hydrothermal alteration and metal mineralization. However, the valuable metals found are relatively low, making it less economical to produce. This condition opens up other opportunities by utilizing the area as a natural laboratory for geological education and sustainable geotourism development. This study evaluates the potential for hydrothermal mineralization-based geotourism through geosite assessment. The study area comprises the Watupatok Formation and the Arjosari Formation, which show silicic, argillic, and propylitic alteration zones. The research methods include geological mapping, rock sampling, petrographic analysis, XRD, FA-AAS, and geosite assessment using the Kubalikova method, covering scientific, educational, aesthetic, and value-added aspects. The results show the presence of mineralization in the form of pyrite, chalcopyrite, sphalerite, and galena, with low levels of valuable metals (Au, Ag, Cu, Pb, Zn). Nevertheless, all three segments of the Grindulu River possess significant geosite value for educational and conservation purposes, with segment 2 considered the most ideal due to its superior accessibility and educational value. This study concludes that the Grindulu River is more appropriate for development as a sustainable geotourism destination based on conservation and geological education rather than mining exploitation.

Abstract

The use of technology such as automatic feed management systems helps create convenience in feeding chickens regularly and optimally for chickens, most village chicken farmers have other activities such as work, etc. therefore farmers can be negligent or forget to feed their livestock, due to this problem, many farmers fail to raise livestock. That is why the idea was born to make an automatic chicken feed system based on the ESP8266 microcontroller that can provide feed for chickens automatically and regularly. This system uses the RTC (real time clock) conveyor as a timer input to run the system, after a predetermined time the ESP8266 will command the DC motor to rotate the spiral screw which will carry the feed from the hoper to the 3 containers where in the test results the feeding time for 3 minutes 40 seconds produces 700grams of feed where the first container contains 300grams, the second container 200grams and the third container 200grams.
