This study aims to analyze the effect of transformer oil purification on oil breakdown voltage and evaluate its benefits in maintaining transformer performance and reliability. Oil purification is a crucial preventive maintenance step to preserve insulation quality and prevent operational failures caused by reduced dielectric properties. The study was conducted through several stages, including data collection, oil purification, measurement of breakdown voltage before and after purification, and evaluation of results. Data collection involved measuring the oil’s electrical properties according to SPLN 49-1:1982 and observing results using a Break Down Voltage (BDV) test. Purification of a Trafindo 400 kVA transformer was performed through visual inspection, connecting the inlet and outlet hoses to the purification machine, and circulating the oil until the breakdown voltage met the required standards. Results indicated that the oil breakdown voltage before purification was below standard due to reduced insulation quality caused by water contamination, charcoal particles, thermal degradation, and dissolved gases that weakened dielectric properties. Additional factors such as electrical stress, mechanical stress, and excessive loading also contributed to insulation deterioration. After purification, the oil breakdown voltage increased significantly to meet the standard of >30 kV/2.5 mm, demonstrating that purification effectively restores the oil’s insulating capacity and supports optimal transformer performance. Analysis confirms that the transformer oil remains suitable for use, and routine annual purification is recommended to maintain reliability, efficiency, and operational performance. This study highlights oil purification as an effective preventive measure for transformer stability, extending operational life, and reducing the risk of insulation failure. The findings provide valuable guidance for transformer maintenance in the electricity industry, ensuring safe and optimal long-term operation.

This study examines the political reconstruction of fair juvenile criminal law in the diversion mechanism at the investigation stage in Indonesia. The background of the research departs from the gap between the empirical conditions (das sein) and the ideal conditions (das sollen) mandated by the Law on the Juvenile Criminal Justice System UU SPPA and the principle of the best interest of the child in the Convention on the Rights of the Child. The research method used is normative legal research with legislative, case, and comparative approaches. The results of the study show that the implementation of diversion faces obstacles in substance, structure, and legal culture: procedural uncertainty, limited capacity of apparatus, lack of supporting facilities, and weak coordination across institutions. This research offers a reconstruction of legal politics in these three domains at once substance, structure, and culture so that diversion truly becomes an instrument of restorative justice that restores, not punishes. The scientific contribution of this article lies in the formulation of a multi-layered policy model, the elaboration of performance indicators for the implementation of diversion at the investigation stage, as well as a matrix of operational recommendations for stakeholders at the police, prosecutor's office, court, and child social service institutions.

Turnover intention is a critical issue that companies must address, particularly in service sectors such as cleaning services, which often experience high employee turnover rates.

The research findings indicate that, on a partial basis, only the Work-Life Balance variable has a significant effect on employee performance, with a significance value of 0.029 and a t-value of 2.311. In contrast, the Physical Work Environment and Interpersonal Communication variables show no significant impact, with significance values of 0.774 (t-value -0.290) and 0.217 (t-value 1.264), respectively. Simultaneously, the three variables do not exhibit a significant influence on performance, as evidenced by a significance value of 0.056 on an F-value of 2.845. The coefficient of determination (Adjusted R²) of 0.240 suggests that the model explains only 24% of the variability in employee performance. These results imply that employee performance at PT Daihatsu Jolo Abadi is more strongly influenced by work-life balance than by the physical work environment or social interactions in the workplace.

Attendance is an essential activity in both educational institutions and companies, serving as an indicator of discipline, presence, and individual responsibility. Conventional attendance systems that still rely on manual journals often face several problems, such as vulnerability to manipulation, data loss, and physical damage. Meanwhile, modern methods such as fingerprint, QR code, RFID, and GPS are not entirely ideal since each has its own limitations in terms of cost, accuracy, user convenience, and potential misuse. For instance, fingerprint systems raise hygiene concerns due to shared use, while QR code and GPS methods are prone to fraud and location spoofing. To address these challenges, this study proposes a face-based attendance simulation system by integrating the YOLOv8 algorithm for face detection and Local Binary Pattern Histogram (LBPH) for face recognition. YOLOv8 was chosen for its ability to detect faces in real time with high speed and accuracy, while LBPH is employed for face recognition due to its robustness in handling variations in facial features and its relatively low computational requirements. This makes the system efficient even when implemented on medium-specification devices. The system was tested on 25 participants with a total of 250 attendance attempts. Based on the confusion matrix analysis, the system achieved outstanding performance with 98.4% accuracy, 98.4% precision, 100% recall, and a 99.2% F1-score. Furthermore, the system automatically recorded attendance dates and times with an average latency of 69.185 ms, proving its capability to operate quickly and reliably in real-world scenarios. Nevertheless, several limitations were observed, such as decreased accuracy when the face moved too quickly during image capture, as well as potential performance degradation under extreme lighting conditions. Despite these challenges, the proposed system demonstrates excellent performance and offers a promising solution for efficient, hygienic, and fraud-resistant attendance management applicable to both educational and professional environments.

This study aims to analyze the effect of communication and work environment on employee morale at the Maritime Affairs and Fisheries Service of Bima Regency.

The results reveal that communication (β = 0.551; t = 18.459; p < 0.05) and work environment (β = 0.401; t = 16.786; p < 0.05) have a significant partial effect on employee morale. Simultaneously, these two variables contribute 94.4% to the increase in employee morale (R² = 0.944; F = 43.288; p < 0.05). These findings indicate that effective communication and a supportive work environment can enhance motivation and productivity among public sector employees. The practical implication of this study suggests that organizational management needs to improve the quality of internal communication and create a conducive work environment to optimize organizational performance.

. The phenomenon of a potential megathrust earthquake predicted to occur in the coming years has raised widespread concern among the Indonesian public, particularly due to the high vulnerability of existing structures. In response to this issue, this study aims to analyze the structural capacity of buildings in resisting seismic forces and lateral loads, with a specific focus on factory structures. As a civil engineering student specializing in structural engineering, the objective of this research is to examine the behavior, performance, and potential failure patterns of building structures under earthquake loads. The research method employs pushover analysis as a tool for structural assessment, while the evaluation process refers to the guidelines outlined in ATC-40. The analysis results indicate that the factory structure is capable of withstanding a lateral load of 108,587.40 kN, with a controlled roof displacement of 1.5 meters. The structural performance level is categorized under the Damage Control (DO) stage, specifically at performance level SP-2, where the structure remains standing under lateral loads but experiences damage requiring repair before reuse. Furthermore, the failure patterns observed reveal a progressive performance of structural elements, shifting from condition B (Basic), IO (Immediate Occupancy), LS (Life Safety), C (Collapse Prevention), up to E (Extreme Damage). These findings highlight the importance of proper structural design and evaluation in enhancing resilience, ensuring safety, and minimizing potential risks from future megathrust earthquake events.

Stable temperature regulation is essential in various industries to maintain product quality and energy efficiency. This study analyzed the water temperature regulation system using PID control through MATLAB simulation and the actual implementation using Thermocontrol and PT100 sensors. In the simulation, the PID control parameters used were Kp = 3.0, Ki = 240, and Kd = 60, while the tuning results in the actual implementation were Kp = 3.0, Ki = 0.5, and Kd = 1.2. The simulation results showed that the system could reach the setpoint faster (±330 seconds), but with a high overshoot (±20.8°C). In contrast, the actual implementation shows more stable performance, with a much lower overshoot (±0.8°C) and a time to the setpoint of about ±345 seconds. These differences in performance can be influenced by environmental factors and the physical characteristics of real systems that are not fully reflected in the simulation. Although the simulation provides faster results, the actual implementation is more adaptive to changing conditions and better able to maintain temperature stability. This research can provide important insights into the development of more effective and reliable temperature control systems for industrial applications, as well as demonstrate the importance of proper tuning in PID control systems to achieve optimal performance.

The results indicate that work discipline has a positive and significant effect on employee performance, while workload does not significantly affect performance. Work discipline also has a positive and significant effect on motivation, and workload has a positive and significant effect on motivation. However, motivation is not able to significantly mediate the relationship between work discipline or workload and employee performance at KSP Semarak Dana Mojokerto.

Compensation for employee has a significant impact on employee discipline and performance. According to Hasibuan, compensation includes all types of income received by employees, both in the form of money and goods, either directly or indirectly in return for the contribution they make. The purpose of this study is to test the compensation and work discipline that affect the performance of PT Prima Soeaka Buana employees. The method used is a descriptive quantitative method, namely with multiple linear regression analysis. The results showed a calculated value of 9.326 > a table of 1.998 and a value of Sig. 0.000 < 0.05 so that compensation and employee performance were partially influential and significant. Seen on the T test, it shows that Ho is rejected and H1 is accepted. For work discipline, there is no positive and partially significant influence on employee performance. Seen in the T test with a tcal value of 0.649 < ttable of 1.998 and a Sig. value of 0.519 > 0.05. So, Ho was accepted and H2 was rejected. In both variables of compensation and work discipline, there is a simultaneous positive and significant influence on employee performance. Seen in the F test with a fcal value of 43.930 > ftable 3.140 and a Sig. value of 0.000 < 0.05. So, Ho refused H3 to accept.

Research on stock splits has been widely conducted in Indonesia and internationally, as stock splits are considered an important corporate action that can influence investor perception and stock performance. However, the motivations and consequences of stock splits remain diverse, ranging from efforts to increase stock liquidity, adjust market price ranges, attract new investors, or signal positive corporate prospects. This study aims to empirically reanalyze the effect of stock splits on trading volume and stock prices of companies listed on the Indonesia Stock Exchange (IDX) during the 2022–2024 period. Specifically, the research investigates whether significant differences exist between trading activities and stock price levels before and after the stock split event. The data used in this study are historical in nature, consisting of stock split announcements, daily trading volume, and stock price movements surrounding the event period. To test the hypotheses, this research employs both the paired-sample t-test and the Wilcoxon signed-rank test as statistical tools. These tests are appropriate because they allow for the comparison of two related samples, namely the stock performance indicators before and after the split. The selection between the two methods depends on the distribution of the data, where the paired t-test is used if the data is normally distributed, while the Wilcoxon test is applied if the normality assumption is not met. This study is categorized as moderate TKT (Technology Readiness Level 4–6) because it uses secondary historical data and focuses on empirical statistical analysis rather than experimental or simulation-based approaches. By examining stock split events within the specified period, this research contributes to the understanding of whether stock splits in Indonesia are primarily cosmetic in nature or if they generate real economic impacts on liquidity and stock valuation. The findings are expected to provide useful insights for investors, market analysts, and policymakers in assessing the relevance and effectiveness of stock splits as a corporate strategy.
