Abstract

Maintaining reliability in the distribution of electricity to customers or the public can be achieved through electrical maintenance. In the SUTM network, maintenance often involves power outages during work, resulting in losses for both consumers and the company because kWh cannot be distributed. Maintenance without power outages can be carried out by the PDKB team, who perform work on network development or installations while the system is energized. This study aims to determine the values of SAIDI and SAIFI, and the amount of kWh before and after the implementation of PDKB at PT. PLN (Persero) UP3 Langsa. Data collection involved observation techniques and analysis of kWh, SAIDI, and SAIFI values. The research results show that maintenance with PDKB can save 1,457,823.97 kWh for customers, generating Rp. 1,135,391,541.48. The SAIDI value is 819.456 Minutes/Customer and the SAIFI value is 9.29 times/customer. In contrast, maintenance without PDKB yielded a kWh value of 3,921,103.2 and a rupiah value of Rp. 3,136,882,560. The SAIDI value is 1533.84 Minutes/Customer and the SAIFI value is 10.04 times/customer. This indicates that the smaller the SAIFI and SAIDI values, the better the service provided by PLN to customers, thereby improving the company's image and avoiding losses due to discontinuity in electricity distribution services.Keywords: PDKB, SAIDI, SAIFI

Abstract

The depletion of fossil fuels has driven significant changes in the global electricity system. Solar Power Plants (PLTS) as a renewable energy source have shown the potential to contribute up to 25% of global electricity generation by 2050. The electricity system often experiences disturbances that can affect its performance and reliability. This study examines the performance of a 1.2 kW hybrid PV system under various load conditions. The system was tested with load variations of 2%, 7%, 22%, and 26% to assess its efficiency and performance. Despite a slight voltage drop of 4V Vac (-1.82%) at higher loads, the hybrid PV system consistently maintained a voltage range of 216-220V Vac, which meets the standard requirements. The system demonstrated high efficiency, averaging over 95%, with a peak efficiency reaching 98.5% at 2% load. These results confirm the effectiveness, safety, and reliability of the system under various load conditions. The findings are based on direct testing and measurements of a 1.2 kW hybrid PV system to evaluate the impact of load variations on its performance. The 1.2 kW hybrid PV system has been proven to be effective, safe and reliable in the face of load variations. These findings support the potential implementation of hybrid PV systems as a future renewable energy solution in the electricity sector

Abstract

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

Abstract

The presence of wild monkeys in the Engineering Prayer Room at Malikussaleh University has become a severe problem for cleanliness and worship activities. Monkeys often damage equipment and disturb the comfort of pilgrims, causing material losses and threatening environmental cleanliness. Traditional methods to repel monkeys have proven ineffective for a long time, so technological solutions such as ultrasonic waves are needed. This study looked at the effects of using various ultrasonic frequencies on monkeys at multiple distances to determine their effective range of distraction. The results show higher frequencies cause more significant interference, especially at close range. At 23 kHz and 26 kHz, monkeys were only disturbed at a distance of 1 and 2 meters, without disturbance at 3 and 4 meters. The frequencies 29 kHz and 32 kHz show interference at a distance of 1 and 2 meters, with variations at 29 kHz at 3 meters. At 35 kHz, the monkeys were highly disturbed at 1 meter, disturbed at 2 meters, and slightly disturbed at 3 and 4 meters. The 38 kHz and 41 kHz frequencies cause significant interference at 1 and 2 meters, and interference is still felt at 3 and 4 meters. Thus, using frequencies above 30 kHz has proven effective in driving away monkeys up to a distance of 4 meters, with the highest intensity of interference at a distance of 1 to 2 meters. It is hoped that using ultrasonic technology can maintain cleanliness, safety, and comfort in prayer activities in prayer rooms and demonstrate commitment to sustainable and environmentally friendly solutions.

Abstract

The reliability of the electricity distribution system is essential to ensure continuous service to consumers. Maintenance is necessary to uphold this reliability. However, on the SUTM (Medium Voltage Overhead Line) network, maintenance often requires power outages, causing losses for both consumers and the company due to undelivered electrical energy (kWh). This study aims to analyze the SAIDI and SAIFI values, as well as the amount of kWh before and after implementing PDKB (Live Line Maintenance) at PT PLN (Persero) UP3 Langsa. The research uses a quantitative descriptive method with data collected through observation and analysis of kWh, SAIDI, and SAIFI metrics. The results show that PDKB-based maintenance saved 1,457,823.97 kWh with a financial gain of Rp. 1,135,391,541.48. The SAIDI and SAIFI values were 819.456 minutes/customer and 9.29 times/customer, respectively. In contrast, maintenance without PDKB resulted in a loss of 3,921,103.2 kWh or Rp. 3,136,882,560, with higher SAIDI and SAIFI values of 1533.84 minutes/customer and 10.04 times/customer. These findings indicate that lower SAIDI and SAIFI values reflect improved service quality, enhancing the company’s image and reducing losses from power distribution interruptions

Abstract

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

Kebutuhan akan energi ramah lingkungan semakin meningkat. Energi matahari menawarkan solusi berkelanjutan yang melimpah. Namun, efisiensi panel surya (PV) sering terhambat oleh panas berlebih. Hal ini dapat menurunkan kinerja konversi daya. Penelitian ini bertujuan untuk meningkatkan efisiensi PV dengan memanfaatkan sistem pendinginan berbasis efek Peltier sebagai solusi inovatif dalam mengatur suhu PV agar tetap stabil dan optimal. Metode yang digunakan dalam penelitian ini adalah eksperimen langsung dengan membandingkan dua kondisi operasional PV, yaitu dengan pendinginan Peltier dan tanpa pendinginan. Data yang dikumpulkan meliputi suhu PV, voltage (Vmp, VOC), arus (Imp), dan daya maksimum (Pmax) untuk setiap kondisi. Sistem pemantauan menggunakan perangkat seperti kamera pencitraan termal dan multimeter panel surya untuk mendapatkan hasil pengukuran yang akurat terkait dengan kinerja PV. Hasil penelitian menunjukkan bahwa sistem pendingin Peltier mampu menurunkan suhu PV secara signifikan, sehingga daya listrik yang dihasilkan oleh PV meningkat. Pada suhu yang lebih rendah, PV dengan pendinginan Peltier menunjukkan efisiensi daya yang lebih tinggi dibandingkan dengan PV tanpa pendinginan. Teknologi ini terbukti ramah lingkungan dan hemat energi, karena tidak memerlukan cairan pendingin atau komponen mekanis yang rumit. Sistem pendingin ini menawarkan alternatif berkelanjutan dalam manajemen suhu PV. Sistem ini dapat diterapkan secara luas untuk meningkatkan efisiensi energi panel surya dan mendukung penggunaan energi terbarukan yang optimal.
