Vocational high school curriculum aimed to prepare pupils for careers in specific industries. Student learning results are significantly impacted by the vocational school learning process. Students' comprehension at SMKN 1 Lhoknga is still deficient since the learning model used is not as effective in maximizing the growth of students' understanding. Applying the Think Pair Share learning paradigm, which is in line with the learner-centered curriculum, is one option to solve this issue. This study employs a quantitative methodology and involved 27 pupils in class X TITL SMKN 1 Lhoknga. Questionnaires and observation sheets are the tools employed. The findings demonstrated that, according to the Think Pair Share learning model, students' average level of activity was 79, with a trend of 79 > 73.3, placing them in the very high category. The percentage of students who responded is 77.04%. it can be concluded that the utilization of the Think Pair Share approach can raise students' engagement with basic electrical materials, according to the study's findings.

In today's world, technological innovations make it easier to choose doors that enhance security, such as those with digital locks that integrate biometric systems such as fingerprint scanners or facial recognition. Previous research has successfully developed a prototype smart door locking system that combines RFID technology, keypads and motion sensors. Radio Frequency Identification (RFID) technology and keypads are two key components of modern security systems. Their use can enhance security in applications ranging from door access control to storage solutions. Motion sensors are devices designed to detect movement in a given area. They work by monitoring changes in the physical environment, such as changes in temperature, sound waves or electromagnetic fields, caused by the movement of objects or people. The method used in this research is the End User Computing Satisfaction (EUCS) approach, together with the BlackBox method. EUCS is a technique used to measure user satisfaction with a system, emphasising the user's experience while interacting with the system. Based on the analysis of the evaluation results, it can be concluded that the RFID-based smart door lock system, equipped with a keypad and a sensor, meets the usability criteria and falls into the good or acceptable category for users. In addition, the black box test results show that the system is functioning as expected.

This study evaluates the efficiency performance of the motor-pump system used by the regional water utility company to identify strategies for improving efficiency. The three-phase induction motor utilized is highly dependent on the quality of the supplied voltage. The primary focus of this research includes analyzing the efficiency performance of the system, examining the electrical parameters of the three-phase induction motor, which include voltage and current imbalance, power factor, and Specific Energy Consumption (SEC). Another focus is the optimization of the motor-pump system and estimating the potential energy savings and operational cost reductions achievable within one year. The research method involves measuring electrical and hydraulic parameters. Electrical parameters were measured using a 3-phase power analyzer (type DW-6195), which records current, voltage, frequency, power, and power factor. Hydraulic parameters were measured using an electromagnetic flow meter for flow rate readings, a manometer for pressure measurements, and a measuring tape to measure the water level in the reservoir tank. All measurement results were tabulated and further analyzed to evaluate the performance of electrical parameters and compare them to the hydraulic performance of the system. The results revealed that the efficiency of the PDAM motor-pump system is below 50%, indicating the need for a comprehensive system revitalization. An inspection of electrical parameters showed that voltage deviation is below 10%, voltage imbalance is below 5%, and current imbalance ranges between 5.65% and 7.35%. All electrical parameters comply with IEEE standards. The power factor, at 0.85, also meets electrical standards. The SEC value, below 0.44 kWh/m³, indicates potential energy efficiency. Based on the pump performance curve study, the pump system can be replaced with a pump unit that has a lower electrical power rating, reducing it from 75 kW to 55 kW, while maintaining its hydraulic performance. Implementing this revitalization is expected to save up to 172,800 kWh of energy per motor per year and reduce by 18.4%.

The level of electrical energy demand in an area reflects the welfare of that community. The greater the use of electrical energy, the higher the community's standard of living, followed by the public's critical attitude towards everything that happens and influences lives, including electricity services. Generally, a network's reliability level can be seen from the size of the SAIDI and SAIFI values on the PLN (state electricity company) side. The calculation and reliability analysis results of the Lhokseumawe ULP above show that the total SAIFI index value is 2.68 times/year. The SAIFI Rayon Lhokseumawe reliability index is categorized as reliable because its value does not exceed the standard set by PLN in SPLN 68-2 of 1986, namely 3.2 times/year. The total value of the SAIDI index is 45.30 hours/year. The Lhokseumawe Rayon SAIDI reliability index is categorized as unreliable because its value exceeds the standard set by PLN in SPLN 68-2 of 1986, namely 21 hours/year. There are certainly differences in infrastructure, electrical equipment, and number of customers in 1986 compared to current years; this has a different influence on electricity reliability values such as SAIDI and SAIFI.

The electronics laboratory of the PTE department still faces issues with conventional keys, limiting access control. To address this, a prototype door security system using e-KTP as an access key was developed through a quantitative experimental method. A system trial was carried out to evaluate the performance of the solenoid and LCD components. Seven e-KTP samples were selected using random probability sampling. The system was built using an ATmega328 microcontroller on an Arduino Nano, with RFID as input and LCD and solenoid as outputs. An admin card was designated to manage user access, including registration and deletion. Testing results revealed an authentication success rate of 87.5%. The distance and response time of RFID reading showed 85.71% accuracy, with a response time of under 2 seconds and a maximum effective scanning distance of 2.5 cm. Additionally, metal was identified as the main obstacle to RFID signal transmission, with a success rate of 83.33% when tested with barrier materials. These results demonstrate the effectiveness and feasibility of the e-KTP-based door security prototype for the PTE electronics laboratory

Controlling access to sterile hospital rooms can be effectively managed using a secure and reliable interlock system based on electrical contactors, which ensures that only one door is open at a time to prevent cross-contamination. This study aims to design and test a prototype of an interlock system for sterile room doors using an electrical contactor as the main controller. The research follows stages of design, testing, and performance evaluation. The system utilizes solenoid door locks controlled by contactors to automate door locking and opening. Testing focuses on measuring the output current of the contactors and the solenoid’s response time during door operations. Results show that contactor 1 outputs 7.63 mA, and contactor 2 outputs 7.64 mA. Solenoid door lock 1 has an average operating time of 0.80 seconds with a delay of 0.89 seconds, while solenoid 2 operates at 0.96 seconds with a 0.97-second delay. The system demonstrates stable performance and complies with sterile room safety standards. It is suitable for hospital implementation and can be further enhanced with remote monitoring and automatic alarm features to improve operational supervision
