Pelaksanaan Pemeliharaan Rutin Belt Conveyer untuk Meminimalkan Downtime pada UBP PLTU Jeranjang
type: item
description: The Field Work Practice (PKL) at UBP PLTU aimed to understand and analyze routine maintenance of the belt conveyor system to reduce downtime. Methods used included direct observation, interviews, data analysis, and post-maintenance condition evaluation. Before implementing routine maintenance, downtime occurred 5–7 times per month due to belt wear, misalignment, motor overheating, and spillage. After applying preventive and condition-based maintenance strategies, downtime significantly decreased to 1–2 times per month, and corrective maintenance needs were reduced by up to 60%. Routine maintenance also helped stabilize motor temperatures, reduce vibration, and extend uninterrupted operating time. Challenges such as delays in spare part procurement and errors in CMMS usage were addressed through technician training and improved monitoring systems. In conclusion, well-planned routine maintenance effectively improves the efficiency and stability of operations. Recommendations include strengthening human resource capacity, enhancing digital monitoring, proactive spare part management, fostering a preventive work culture, and conducting regular evaluations and audits.

Analisis Perhitungan Tegangan Eksiter Untuk Menghasilkan Tegangan Generator 6,3 kV Kondisi Tanpa Beban Pada Mesin ZV PLTD Ampenan
type: item
description: Analysis of the excitation voltage required to produce an output voltage of 6.3 kV on the ZV-type synchronous generator, Unit 2, at PLTD Ampenan under no-load conditions. The stability of the generator's output voltage is significantly influenced by the excitation voltage, which is regulated through the Automatic Voltage Regulator (AVR) system. The study was conducted using two approaches: direct field measurements and a mathematical approach based on the magnetic induction voltage formula. Field measurements indicated that the average excitation voltage required was 7.24 VDC, while the mathematical approach yielded a value of 7.7 VDC. This discrepancy is attributed to the use of assumed parameters, such as the number of windings on the stator and rotor, as well as the omission of certain technical factors, including temperature, impedance, reactance, and voltage losses. This analysis aims to provide a technical understanding of the influence of excitation voltage on generator performance and to serve as a foundation for controlling and maintaining the excitation system to ensure that the generator's output voltage remains stable. It is expected that this study will support the reliability of power supply at PLTD Ampenan and serve as a technical reference in the operation of synchronous generators.

type: item
description: engukuran daya listrik dilakukan dengan Empat metode pengukuran daya listrik voltmeter-amperemeter, tiga voltmeter, tiga amperemeter, dan wattmeter dievaluasi untuk menentukan tingkat akurasi pada berbagai beban berdasarkan Hukum Ohm dan teori daya listrik yang mencakup daya aktif, reaktif, dan semu. Pengukuran menunjukkan bahwa hasil daya meningkat seiring bertambahnya beban, tetapi akurasi bervariasi di antara metode. Wattmeter memberikan hasil paling akurat dengan kesalahan terkecil, sedangkan tiga voltmeter menghasilkan kesalahan terbesar karena keterbatasan alat ukur. Hubungan antara arus dan daya sesuai dengan Hukum Ohm, sedangkan tegangan sumber tetap stabil meskipun arus meningkat akibat beban yang bertambah. Pilihan metode pengukuran berpengaruh signifikan terhadap akurasi hasil, dengan wattmeter direkomendasikan untuk aplikasi yang membutuhkan presisi tinggi, sementara metode lainnya lebih cocok untuk kebutuhan tertentu. Temuan ini diharapkan menjadi referensi dalam memilih metode pengukuran daya listrik untuk keperluan praktis maupun penelitian lebih lanjut.

Implementasi Sinkronisasi File Server Dengan Secure File Transfer Protocol
type: item
description: The web serves as a platform for disseminating and retrieving information. However, during periods of server overload, server performance and client access times can significantly slow down. One viable solution to address this issue is server clustering, where multiple servers are combined into a unified system. Among the methods employed in such scenarios is load balancing, which aims to evenly distribute client requests across multiple servers to optimize performance. Nevertheless, ensuring file synchronization across these clustered servers remains crucial to maintain file availability. Python's watchdog library provides a solution for monitoring file changes and facilitating file synchronization using Secure File Transfer Protocol (SFTP). In synchronization tests, file transfer speeds ranged from 39.54 to 42 Mb/s, with transfer durations varying between 2.02 seconds and 19.05 seconds for file sizes ranging from 10MB to 100MB. Concurrent synchronization experiments revealed that 9 files failed due to data collisions caused by simultaneous file transfers to both servers. Furthermore, the experiments successfully differentiated and compared the MD5 values of each file, demonstrating the capability to detect changes when files were created, deleted, or modified during alternate synchronization processes.

PERENCANAAN PEMBANGKIT LISTRIK TENAGA SURYA ROOFTOP KAPASITAS 600 WP ON GRID
type: item
description: The increasing demand for electric power, along with an economic growth estimated at about 7%-10% per year, means that electricity consumption in Indonesia will rise. As a country with a tropical climate, Indonesia has the potential for renewable energy in the form of solar energy with an average irradiation of 4.5 – 4.8 W/m2. Therefore, the development of solar power plants (PLTS) is highly necessary, leading to the issuance of Ministerial Regulation ESDM Number 26 of 2021, which contains regulations on the installation of rooftop PLTS. This study aims to obtain a 600 Wp capacity on-grid rooftop PLTS system in accordance with Permen ESDM Number 26 of 2021. It also seeks to determine the energy production (kWh/day) and the efficiency of the 600 Wp on-grid rooftop PLTS system. The results obtained from this study include achieving an on-grid rooftop PLTS system with a 600 Wp capacity, obtaining a total production in 1 day over 3 days of 2.3 kWh on day 1, 2.1 kWh on day 2, and 2.2 kWh on day 3. Additionally, the average system efficiency was found to be 9.06% on day 1, 9.12% on day 2, and 8.85% on day 3. These results are based on measurements taken in August, when, according to the solar cycle, the sun is north of the equator, whereas the installation point of the PLTS is in the southern hemisphere.

Rancang Bangun Prototipe Pengusir Hama Burung Dan Tikus Sawah Berbasis IoT Terintergrasi Aplikasi Android
type: item
description: Pests are one of the scourges that often lead to crop failure. Some challenges faced by farmers in growing rice include rat and bird pests. Therefore, this study designs a system to repel pests. It uses an ESP32 microcontroller connected to a PIR (Passive Infrared Sensor) to detect pest movement. When pests are detected, the system will activate several pest repelling components, including a buzzer to produce a sound that scares rats, an electrified wire fence to repel rats, and a servo that moves to repel birds, where the servo will also be active if an anemometer detects winds of 3000-4000 m/s. The tool is monitored in real time using Arduino Cloud IoT software connected to the internet. The purpose of monitoring is to determine the success of the tool in repelling pests. This prototype system has been tested on a small scale, with separate tests for rat and bird pests. The PIR sensor successfully detected pest movement within a range of up to 4 meters. From the testing on 8 birds, 5 were successfully repelled by the servo movement. For rats, the buzzer effectively disturbed rats up to a distance of 40 cm, and with the support of a high voltage module kit, rats were successfully repelled up to a distance of 80 cm. Then the pests can be monitored in real time using Arduino Cloud IoT software. Then field testing was conducted on the prototype for 6 days, where the development of the success rate of the tool was observed from 3 days without repelling and 3 days of repelling to find out the difference in the number of pests repelled. The results of the testing showed a decrease in rat and bird pests, with a decrease in the number of rats and birds detected.
