timulation, individualized consideration, and value-based motivation, is thought to have a significant influence on improving employee productivity. However, how such mechanisms work in the context of the automotive industry in Indonesia still requires in-depth exploration. Using a qualitative approach, this research adopts a case study method to analyse the perceptions, experiences, and interactions of employees and managers in responding to transformational leadership styles. Data was collected through in-depth interviews with managers and employees at PT Mitsubishi Electric Automotive Indonesia, as well as participatory observation in the work environment. Thematic analysis was used to identify key patterns related to motivation, work engagement, and productive behaviour change. The results revealed that transformational leadership contributes to increased productivity through three main mechanisms: (1) strengthening the psychological climate that encourages innovation, (2) increasing organizational commitment through identification with the company's vision, and (3) optimizing team collaboration through inspiring communication. However, implementation challenges were also identified, including resistance to change and a gap between management expectations and employees' adaptive capacity. The implications of this study provide practical insights for companies in designing more effective leadership development programs, while enriching the human resource management literature with a contextual perspective from the Indonesian automotive industry. Policy recommendations include case-based leadership training, participatory feedback approaches, and integration of transformational values in corporate culture.

This study aims to analyze the electrical installation condition of SDN 002 Bontang Utara through the evaluation of lighting systems, power requirements, conductors, protection systems, and air conditioning based on PUIL 2011 standards and DIALux simulation. The study employed a field research method with a quantitative descriptive approach through observation, technical measurements, documentation, and lighting simulation analysis. The findings indicate that the school’s electrical installation still exhibits several discrepancies with actual technical requirements, particularly regarding the number and capacity of lamps, air conditioner capacity, and electrical power demand. DIALux simulation revealed that several rooms have not yet met the required lighting standards, while power analysis demonstrated that the actual demand of 25,794 VA exceeds the installed capacity of 22,188.8 VA, thereby necessitating adjustments to the protection and conductor systems to enhance installation safety and efficiency. The study concludes that the electrical installation of SDN 002 Bontang Utara requires improvements in lighting, cooling systems, power capacity, and electrical protection. The novelty of this research lies in its integrated evaluation of elementary school electrical installations through field analysis, PUIL 2011 technical calculations, and DIALux simulations across rooms with diverse functions, thereby producing more comprehensive and applicable recommendations.

electrical installation standards. The research approach involved field surveys to obtain empirical data, measurements of lighting intensity, calculations of the required number of lighting points according to the function and characteristics of each room, as well as technical analysis of installation components, including conductors and protection systems. All observed data were compared with theoretical calculations to identify the level of conformity as well as potential deviations that could cause problems. The findings indicate that although the electrical installation remains operational, there are significant discrepancies, particularly in the distribution of lighting intensity, the number of lighting points, and the selection and placement of protective components that do not fully meet the standards. These discrepancies affect the optimality of lighting, reduce user comfort, and present potential safety risks. Therefore, this study recommends adjustments to the installation design, prioritizing the optimization of the lighting system, the use of standard-compliant components, and the implementation of energy efficiency principles as part of a comprehensive improvement effort. The implications of these findings highlight that regular evaluations and updates of electrical installations in educational buildings are essential to create a safe, comfortable, and productive learning environment. Thus, the results of this research not only provide practical contributions for school management but also offer a scientific basis for developing technical standards of electrical installations that are more responsive to educational needs.

the demand for electricity supply is projected to continue rising. In Indonesia, PLN (Perusahaan Listrik Negara) is the main electricity provider, but it often faces challenges in meeting this demand, especially with frequent power outages that disrupt industrial and societal activities. To address this issue, many companies have turned to using generator sets (gensets) as an alternative solution to ensure a stable energy supply. Although the use of gensets provides energy independence, it requires a significant investment. Therefore, an in-depth analysis of the efficiency and economic feasibility of using gensets is necessary. This study aims to analyze the use of gensets at PT. Teladan Prima Agro Bukit Permata Mill, located in Kaubun, East Kutai, focusing on technical-economic aspects such as Present Value (PV), Future Value (FV), Net Present Value (NPV), Internal Rate of Return (IRR), and Break Even Point (BEP). Data collected directly from the field includes genset specifications, electricity load, energy consumption, fuel usage, and genset operations. The analysis results indicate that the 455 KVA genset is capable of meeting the factory's electricity needs with an initial cost of IDR 649,649,996. The NPV calculation shows a value of IDR 880,380,813, with an IRR of 6.63%. The BEP is achieved in the 12th month with a profit of IDR 109,645,114. Based on these results, the operation of the genset at PT. Teladan Prima Agro Bukit Permata Mill is considered feasible and profitable in the long term.

mportant equipment in a substation is a transformer, and the protection device used is a lightning rod. With its good characteristics, the arrester plays a role in bypassing lightning currents so that the equipment does not produce high overvoltages. The analysis results show that the maximum distance between the arrester and the transformer is 10.96 meters, while the installation distance in the field is 3.2 meters, so the arrester can still protect the transformer because it is still lower than the maximum distance. Allowed. After the arrester turns on for 9.54 μs, the voltage on the transformer will drop. And because the BIL of the transformer is 650 KV and the peak voltage reaches 751.3 kV at 300 μs, the arrester can still protect the transformer.

the ship. Ship maneuvering, on the other hand, refers to the ability to turn and pivot while sailing. This ability is crucial for the safety of the ship, especially when operating in restricted waters or near ports. The blackout occurs as a result of generator overload or the inability of an electrical voltage and current to flow too high or too large. The load is too high because the bow thruster consumes too much electrical voltage. In fact, on KM. Dharma Kartika IX, the generator has already supplied a significant amount of electricity to various parts of the ship, including the lighting system throughout the ship, from the mast to deck 3, the cooling system, and several navigation systems. The aim of this research is to understand and explain the causes of blackouts in the electrical system of KM Dharma Kartika IX during maneuvering and to find solutions that should be implemented in case of problems with the generator unit. The method I used to gather this data is through direct observation during seagoing service on the subjects under examination.
