Abstract

The Substation is a sub-system or a unit of the electric power distribution (transmission) system. Distribution (transmission) is a sub-system of the electric power system. This means that the substation is a sub-sub-system of the electric power system. Therefore, one of the most important equipment in the substation is the current transformer (CT) which is a very important equipment in the substation, where this device is used to convert a large current value into a smaller current value for measurement and protection purposes. The Current Transformer must be in good condition in order to be able to transform the current accurately and thoroughly. The research method carried out in the form of literature studies is to find and collect various references from books and journals as well as previous research related to the research title that the author took, in addition to that the author takes and collects related data needed in the form of CT maintenance data at PT. PLN (Persero) ULTG Rangkasbitung then analyzed all the data that had been collected. The measurement of isolation resistance is carried out at the beginning of the test intended to find out the isolation conditions of the current transformer at an early stage and to avoid subsequent test failures. The test results of the isolation resistance of primary-ground CT in phase R are 130000 MΩ, which means that the CT is still in good condition. Meanwhile, the delta tan test on CT with R phase is 0.17%, which means that the ct is also still in good condition.

Abstract

The development of transportation technology encourages companies to improve vehicle monitoring systems to be more effective and measurable, particularly in addressing speeding violations that can increase accident risks and reduce operational efficiency. This study aims to analyze the implementation and effectiveness of using a buzzer integrated with the Teltonika FMB910 GPS module as a vehicle speed warning indicator at PT. Lacak Cipta Aktual. This research employs a qualitative descriptive method with a case study approach, where data were collected through observation, interviews, and documentation during a one-month industrial internship and analyzed using the Miles and Huberman model, including data reduction, data presentation, and conclusion drawing. The results show that the system is capable of detecting overspeed conditions and automatically activating the buzzer when the vehicle speed exceeds the predefined threshold of 80 km/h. Based on logbook data, the system achieved a success rate of 93.9% in responding to overspeed conditions. The use of a buzzer is proven effective in providing immediate warnings to drivers, thereby improving driver awareness and speed control. However, the system still has limitations, particularly its dependence on GPS signal stability and vehicle electrical conditions. Overall, this study demonstrates that the integration of GPS and a buzzer provides a simple, effective, and cost-efficient solution to enhance driving safety and fleet management efficiency.

Abstract

Learning activities in the Basic Vocational Program subject at SMKN 1 Cilegon are still predominantly conducted through conventional instructional methods, accounting for 84.4% of classroom practices and limiting student’s active engagement. This study developed an interactive learning module using the Genially platform integrated with a deep learning approach for the topic of Active and Passive Electronic Components and evaluated its feasibility, practicality, and effectiveness through a Research and Development (R&D) method based on the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The participants were 34 tenth-grade students of Mechatronics Engineering at SMKN 1 Cilegon, with data collected through expert validation instruments, student response questionnaires, and pretest–posttest assessments. The results showed that the module was highly feasible, with validation scores of 71 from media experts (X ≥ 54) and 79 from material experts (X ≥ 60), while student responses indicated very high practicality with an average score of 84.5 (X ≥ 72). In terms of effectiveness, learning outcomes improved significantly, as shown by an increase in the average score from 51.6 on the pretest to 91.2 on the posttest, with an N-Gain value of 0.822 categorized as high, confirming that the developed module is feasible, practical, and effective in enhancing student learning outcomes and supporting student-centered learning in vocational education.

Abstract

Three-phase induction motors are the primary drive components in various modern industrial systems demanding high energy efficiency and operational reliability. However, conventional speed control methods have proven to waste electrical power and are less adaptive to dynamic load changes. Therefore, this study aims to design and fabricate an integrated speed control panel for a 3-phase AC induction motor utilizing a Chint NVF5-3.7/TS4-B Variable Speed Drive (VSD). In contrast to qualitative approaches, this research applies an applied quantitative methodology based on engineering design, validated through a literature review and empirical observations at PT. Tiga Kreasi Indonesia, Tangerang Regency. The panel prototype was precisely fabricated with dimensions of $800 \times 550 \times 300$ mm, using 2 mm thick steel plates coated with RAL 7035 paint, and complies with the IP42 protection standard. Its electrical architecture is integrated into four main subsystems: incoming, inverter, outgoing, and manual control system. Operational testing results validate that the VSD effectively regulates rotor rotation linearly against its output frequency, yielding measured speeds of 1,713 rpm at 35 Hz and 2,709 rpm at 50 Hz. Although the empirical evaluation revealed an escalation in slip value during low-frequency operations due to flux weakening, comprehensively, the implementation of this VSD control panel is proven reliable in regulating speed and possesses a highly significant potential for reducing power consumption compared to conventional Direct on Line (DOL) operations.
