Abstract

Arch flash is a disorder that often occurs in the electrical system of an industry or factory. In this research focusing on the analysis of the protection system by considering arc flash, it will be discussed in detail at the existing factory in East Java, namely PLTU Paiton unit 3 which is developing a unit with a capacity of 1x815 MW. The electrical system at PLTU Paiton unit 3 discusses only high and medium voltage systems. In order to support the continuity of the plant, to connect the Java-Bali electricity system, it is necessary to have a good protection coordination system to avoid black out due to one of the impacts caused by the arc of fire. After coordination of protection in the Paiton PLTU unit 3 system, arc analysis will be simulated with IEEE 1584-2002 standard calculations to find the  magnitude of energy incidents and determine the safety limits of workers and also personal protective equipment according to NFPA 70E standards. The results of the study after resetting the protection coordination of PLTU Paiton unit 3 using differential rele on the SWGR-3A bus incident value of arc energy and Flash Protection Boundary (FPB) value decreased which originally reached a level outside level 4 (>40cal / cm2) to level 3 (8.1-25cal / cm2), on the SWGR-3B bus the incidence energy value was at level 3 (8.1-25cal / / cm2) dropped to level 2 (4.1-8cal / cm2), for coal hand sys bus SWGR A the energy incident value from level 3 (8.1-25cal//cm2) drops to level 0 (0 -1.2cal/cm2), while for the coal hand sys SWGR B bus the energy incident value when existing conditions reach level 3 (8.1-25cal//cm2) drops to level 0 (0-1.2cal/cm2). After obtaining the energy level of the bus, then personal protective equipment can be determined.

Abstract

Electrical energy is one of the basic human needs in carrying out various activities or daily activities, especially in office buildings such as office buildings of state higher education institutions, namely the Sumatra Institute of Technology (ITERA). Office buildings are the third highest consumer of electrical energy after shopping centers and hotels. The high demand for electrical energy requires the user sector to make efficiency in energy use. Before making efficiency, it is necessary to know the profile of electrical energy consumption including energy consumption intensity (ECI) and significant energy users. Therefore, in this study, an analysis of electrical energy consumption in each ITERA office building was carried out, through observation and interviews according to SNI / ISO 50002: 2018 energy audit procedures. The results obtained show that the total energy use of the 6 largest buildings (A, B, C, D, E, and F) in May 2023 is 144768 kWh and from the calculation of the ECI value is in the very efficient category (7.44 kWh/m2/month). From 6 existing buildings, there are 3 buildings that are very efficient, 1 building is efficient, and 2 buildings are quite efficient. Then, significant energy users were found by 83% in building C AC. Recommendations for saving energy in the effort of energy conservation and efficiency that can be done include, making changes in habits / patterns of use of electrical energy user equipment, especially in air conditioners and dispensers, so as to save electricity 2-21%, and retrofitting refrigerant AC types of split ducts and cassettes that still use R-22 with MC-22 which can save electricity 15-25%.

Abstract

Electrical energy is energy that cannot be released from daily activities at home, all elec-tronic equipment requires electrical energy, one source of electrical energy is the electrici-ty company PT. PLN (Persero) and as an alternative source of electrical energy, a home can use solar panels installed on the roof as a small scale power generator or can be called Solar Home System (SHS), but electrical energy obtained is very dependent on the radia-tion received by the solar panels, therefore, to obtain optimum solar radiation, it is neces-sary to calculate the azimuth angle and tilt angle which can be used as a reference for in-stalling solar panels. So mathematical calculations are needed to calculate the maximum azimuth angle and tilt angle. Mathematical modeling is used to calculate solar energy in-stalled at coordinates 7.7° south latitude, in that coordinate, average solar radiation can get from Meteorological, Climatological, and Geophysical Agency on horizontal surface, then calculation the declination angle, latitude angle, hour angle, azimuth angle and tilt angle to get value of incidence angle. Value of the declination angle, latitude angle, and hour angle are constant, while the azimuth angles divide into four directions, it's 0°, 90°, 180°, and 270° and the tilt angles are 20°, 25°, and 30° on skillion roof design. The results of the calculation and analysis of the movement of the sun for one year show that, by calculating the average solar radiation in a year, the roof of the house in the form of a skillion with an azimuth angle in the 0° gets the most optimal solar energy at an angle of 20° with an aver-age solar radiation of 442,96 W/m2 in one year.

Abstract

Hospitals, as large energy consumers, must adopt efficient energy-saving measures due to cost increases, regulations, and climate change concerns. In this study, an electrical energy audit was conducted at Pratama Tapan Hospital to identify energy-saving opportunities and recommend equipment replacements or technology upgrades. The primary objective was to determine the Energy Consumption Intensity (ECI) and analyze the potential for energy savings. The audit re-vealed an ECI value of 10.33 kWh/m²/year, highly efficient by ASEAN-USAID standards. However, 100% of rooms didn't meet the SNI 03-6197-2000 light intensity standard, causing discomfort. The study recommends installing specific light fixtures and adjusting lamp power to comply with the standard. These findings offer valuable insights for healthcare institutions striv-ing to achieve sustainability goals.

Abstract

Based on the latest data from the Serang Regency Central Statistics Agency in 2022, the Open Unemployment Rate (TPT) of Vocational High School (SMK) graduates is still relatively high compared to graduates of other levels of education, namely 12.87%. Apart from that, from the results of observations, there are still many vocational school students who still need to be ready for work. This is because the industrial internship program has not been able to optimize students' work readiness, students' work motivation still needs to be visible, and students' communication skills still need to be improved for their readiness to enter the world of work. This research seeks to determine the influence of industrial internship, work motivation, and communication skills on vocational school students' work readiness. This research uses a quantitative approach to answer the research hypothesis, which asks whether industrial internship, work motivation, and communication skills are positively correlated with vocational school students' work readiness. This research used a questionnaire distributed to 180 students in seven vocational schools in Serang Regency. This research proved that industrial internship, work motivation, and communication skills significantly influence work readiness (7%). For the conclusions and limitations of existing research, this research provides several suggestions for improving vocational school students' work readiness by paying more attention to the variables of industrial internship, work motivation, and communication skills.

Abstract

The lack of interest in technopreneur-based entrepreneurship raises concerns about stu-dents' readiness to face the demands of an ever-changing and dynamic job market. There-fore, this research aims to understand the factors that influence interest in technopreneur-based entrepreneurship, especially students in Vocational Education related to leadership and creativity. The research method used was a survey followed by data collection through questionnaires distributed to Vocational Education students, followed by multiple regression analysis using the T test and F test to test the three proposed hypotheses. The research results show that the spirit of leadership and creativity significantly influences the entrepreneurial interest of technopreneur-based Vocational Education students. These two variables together explain most of the variation in entrepreneurial interest, with 91.4% of the variation explained by the combination of the two factors. These findings highlight the importance of developing leadership qualities and stimulating student creativity to foster interest and success in technopreneur-based entrepreneurship.

Abstract

The greater the power losses, the higher the loss costs for the transformer. These losses can occur due to load, no-load, and load imbalance factors. This study aims to obtain the cost of losses incurred due to these three factors for ten years (2023-2033). The estimated cost of losses due to unbalance is obtained from the calculation of power losses in the neutral of the transformer, the cost of no-load losses is obtained from the losses of the iron core in the transformer, In contrast the cost of load losses is influenced by the development of the load and the interest rate for each year. As a result, the greatest power losses occur under unbalanced conditions with an average load for ten years of 88.68%, followed by no-load conditions of 11.10% and 0.21% load. The total power losses for ten years amounted to Rp. 3,029,196,416.64.
