Abstract:This study developed and evaluated a standalone, non-intrusive radio frequency identification (RFID)-based elevator access control system for a four-story residential building. The system used an Arduino Uno, an MFRC522…
RFID reader, and relay interfaces to regulate access to Floors 2, 3, and 4. Authorized card identifiers and floor permissions were stored locally, enabling offline operation without an external database or network connection. The relays interfaced only with the elevator push-button circuits and did not modify the original controller, motor drive, door mechanism, or safety system. Performance was evaluated using 47 registered cards and three unregistered cards, with each card tested 50 times, producing 2,500 authentication trials. Under the tested conditions, all registered cards were correctly authenticated according to their assigned floor permissions, while all unregistered cards were rejected. The system achieved 100% authentication accuracy, 100% correct relay activation, and 100% unauthorized-card rejection. Stable card detection was obtained at distances of up to approximately 1 cm. The first-floor button remained independent of the RFID module to preserve minimum accessibility during module failure. The proposed system provides a practical and low-cost retrofit solution for floor-specific elevator access control in small residential buildings.

Abstract:This study aims to evaluate the stability of three rock slopes in an artisanal kaolin mine in Semin, Gunungkidul, Yogyakarta, Indonesia, using deterministic and probabilistic approaches, and to identify the geotechnical…
parameters most influencing slope stability. The evaluation is conducted in compliance with Indonesian Mining Regulation (Kepmen ESDM No. 1827 K/30/MEM/2018) to provide quantitative geotechnical evidence for a mine that has been operated without prior formal geotechnical assessment. Field data were collected using the scanline method to characterize rock mass discontinuities. Laboratory tests comprising direct shear and physical properties tests were conducted to determine cohesion (c), friction angle (ϕ), and unit weight (γ) for each slope. Seismic coefficient (ks = 0,0913) was incorporated as a dynamic loading parameter. Slope stability was analyzed using the General Limit Equilibrium (GLE) method to obtain the deterministic Factor of Safety (FoS). Monte Carlo simulation (N = 10.000 iterations) was applied to determine the Probability of Failure (PoF), coefficient of variation of FoS (CoV), and reliability index (β). Sensitivity analysis was performed to quantify the contribution of each geotechnical parameter to FoS reduction. Results show that FoS values ranged from 2,019 (Slope III) to 10,55 (Slope II), all exceeding the regulatory minimum of 1,1. The PoF was 0,00% for all three slopes, well below the maximum allowable limit of 25%, with reliability indices ranging from 5,70 to 31,38. The CoV of FoS ranged from 3% to 9%, indicating low dispersion in stability outcomes despite parameter variability. Sensitivity analysis identified cohesion as the most dominant parameter in Slopes I and II, contributing 28% and 31% to FoS reduction respectively, while Slope III exhibited near-equal contributions from cohesion (20%) and friction angle (21%), reflecting its lower shear strength conditions. All three slopes satisfy the acceptance criteria of Kepmen ESDM No. 1827 K/30/MEM/2018 under current geotechnical and geometric conditions. The combined deterministic-probabilistic approach provides a more comprehensive slope safety assessment than deterministic analysis alone and is recommended for application in artisanal kaolin mining operations. Cohesion is identified as the critical parameter to be monitored and preserved to maintain slope stability.

Abstract:This study aims to systematically analyze the influence of Occupational Safety and Health (K3) on employee productivity through organizational commitment and company culture using the Systematic Literature Review (SLR) approach.…
pproach. K3 has a strategic role in creating a safe and healthy work environment, which not only contributes to reducing the number of occupational accidents and occupational diseases, but also has implications for improving employee performance and productivity. However, the relationship between K3 and productivity is not always direct, but rather influenced by psychological and organizational factors, especially organizational commitment and company culture. This study uses the SLR method with PRISMA steps. Articles filtered from the Scopus journal database with the topic The study process is carried out systematically through the stages of identification, screening, feasibility assessment, and determination of final articles in accordance with the inclusion and exclusion criteria that have been set. The results of the study show that the effective implementation of K3 has a positive effect on employee productivity both directly and indirectly. Organizational commitment acts as a mediator that strengthens these relationships through increased employee loyalty, attachment, and responsibility, while a company culture that supports safety values strengthens collective norms and performance orientation in Indonesia published between 2021 and 2026 in a total of 5,863 articles. After elimination according to the criteria, only 41 articles were considered and extracted. These findings confirm that K3 is not only seen as a regulatory obligation, but as a strategic instrument in human resource management to improve the sustainability and competitiveness of the organization. Theoretically, this study integrates the concepts of K3, organizational commitment, company culture, and productivity in a comprehensive conceptual framework, and practically provides managerial implications in strengthening performance based on work safety.
