Abstract

The increasing need for electrical energy requires the reliability of good electrical power distribution. Intentional or unintentional blackouts caused by electrical disturbances will certainly be detrimental to both PLN parties themselves. Several parameters that can be used as a reference in determining the reliability of a distribution system are by calculating SAIFI (System Average Interruption Frequency Index) which is an index calculation of the average number of disturbances during each month and SAIDI (System Average Interruption Duration Index) which is an index of the average duration of disruption to the system for one month. Analysis of the condition of the level of reliability of the distribution system at PT. PLN (Persero) ULP Fakfak aims to determine the monthly reliability of SAIDI and SAIFI in the distribution system at PT. PLN (Persero) ULP Fakfak whether it still meets the SAIDI and SAIFI target values at PT. PLN (Persero) ULP Fakfak.. The method used is a qualitative-descriptive approach. The results obtained are the SAIDI and SAIFI PT eligibility standard values. PLN (Persero) ULP Fakfak in the month standard used for SAIDI is the limit of 79.01 hours / plg - 308.00 hours / plg and the SAIFI standard is 0.56 times / plg - 1.86 times / plg. From the results of SAIDI calculations for 5 months from February - June, it can be seen that in May the SAIDI value was much better than the target set by PLN, namely 17.24 hours / plg. Meanwhile, SAIFI according to the calculation results was 0.16 times / home from 1.38 times / home in May set by PT. PLN (Persero) ULP Fakfak. Keywords: SAIDI, SAIFI, Reliability, Distribution Systems.

Abstract

This research aims to develop an effective and reliable work safety protection system based on Arduino Uno. The system is designed to detect hazards in the workplace, such as suspicious movements that may cause accidents for industrial workers. Arduino Uno is used as the brain of the system, and sensors connected to the microcontroller serve as input devices that detect actions not in accordance with safety procedures. When the sensors detect a hazard, Arduino Uno will activate an alarm and automatically take the necessary control actions. This research involves programming the Arduino Uno, selecting the appropriate sensors, hardware integration, and thorough system testing. The developed system is expected to enhance workplace safety and provide better protection for workers. System testing is conducted using a simulated work environment that depicts different hazard scenarios. The test results show that the Arduino Uno-based work safety protection system functions as expected. The installed sensors accurately detect hazards such as excessive temperature, fire, toxic gases, excessive vibrations, and unwanted movements in the work area. Arduino Uno receives signals from these sensors and quickly responds by activating alarms and taking appropriate protective actions. Interpretation of the test results indicates that the developed system can effectively help identify potential hazards and provide the necessary protection for workers in the manufacturing industry

Abstract

Fakfak Regency, West Papua Province is one of the oldest regencies in Papua. However, electricity problems are still a scourge that has not yet been resolved properly. So far, the mainstay of power plants in Fakfak Regency is the Diesel Power Plant (PLTD) which is highly dependent on the supply of Fuel Oil (BBM) and the reliability of the Diesel Engine. In fact, Fuel Oil (BBM) is one of the natural resources that cannot be renewed. For this reason, it is necessary to conduct a study on New Renewable Energy (EBT) that has the potential to be developed in Fakfak Regency. There are several rivers that have the potential to be developed as Micro Hydro Power Plants (PLTMH) in Fakfak Regency. The existence of Micro Hydro Power Plants (PLTMH) in Fakfak Regency is one of the real solutions to the power outages that still often occur in Fakfak Regency. Through this study, it is hoped that there will be a mapping of the energy potential that can be produced by several rivers in Fakfak Regency if used as Micro Hydro Power Plants (PLTMH). In addition, the potential of Micro Hydro Power Plant (PLTMH) will support the transition of power plants in Fakfak Regency. Another objective is to support environmental conservation efforts (nature and culture) and increase community participation in the management of existing natural resources, thus providing economic benefits to the local community. The research was conducted through surveys and direct measurements where the measurement results will be calculated to determine the potential river flow discharge and the potential for power generation. The results of the measurements and calculations obtained an average discharge of the Sakartemen River of 3.1m3/second which based on the measurement of the effective fall height (Heff) of the flow was obtained at 4 m. With these results, it can be estimated that the electrical power generated is 104,260 kW.

Abstract

Penelitian ini memanfaatkan data gerak yang direkam untuk memperkirakan gerakan maju kursi roda otomatis menggunakan teknik interpolasi Lagrange. Metode ini dipilih karena kapasitasnya untuk menghasilkan perkiraan yang tepat tanpa kompleksitas komputasi yang umumnya terkait dengan metode interpolasi diferensial terpisah seperti interpolasi Newton. Studi ini melibatkan pengukuran jarak lurus, jarak lateral, dan waktu yang dibutuhkan untuk setiap percobaan. Hasil evaluasi menunjukkan bahwa teknik interpolasi Lagrange menghasilkan perkiraan yang akurat pada titik evaluasi penting. Pada x=5000, interpolasi Lagrange memprediksi -5,43269 × 1015 dengan kesalahan 0,26665, sedangkan pada x=10000, prediksinya adalah -7,83405 × 1018 dengan kesalahan 0,78549. Studi ini menyimpulkan bahwa interpolasi Lagrange adalah metode yang efektif untuk memodelkan pergerakan kursi roda otomatis menggunakan data yang tersedia. Namun, perhitungan kompleks yang terlibat memerlukan manajemen distribusi data yang cermat dan peningkatan metode untuk mengatasi keterbatasan ini di masa depan. Studi ini berkontribusi pada pengembangan teknologi yang bertujuan untuk meningkatkan kualitas hidup individu dengan kebutuhan mobilitas khusus.

Abstract

Bangsa Indonesia dituntut mempersiapkan SDM agar bisa bersaing dan beradaptasi dalam revolusi industri 4.0 dan masyarakat 5.0. Lulusan pendidikan kejuruan dituntut kesiapannya dalam percaturan dunia tenaga kerja di tingkat nasional maupun global khususnya penggunaan teknologi berbasis temuan-temuan baru. Dalam hal ketenagakerjaan kita patut khawatir sumber daya manusia tidak akan mampu bersaing dengan tenaga kerja dari negara lainnya yang telah mempersiapkan diri dan mempunyai kualitas yang lebih baik. Salah satu cara yang dapat dilakukan untuk meningkatkan kompetensi lulusan Sekolah Menengah Kejuruan (SMK) adalah implementasi pembelajaran berbasis industri (PBI) karena siswa dapat memperoleh pengalaman belajar yang nyata dalam suasana industri/dunia kerja sesungguhnya. Konsep yang diterapkan dalam PBI adalah Competence Based Training (CBT) dan Production Based Training (PBT). Pemerintah Indonesia telah menerbitkan beberapa regulasi tentang PBI sejak tahun 1990 hingga saat ini. Upaya tersebut dilakukan agar kualitas lulusan SMK memiliki daya saing global dengan kompetensi sesuai kebutuhan dunia usaha dan dunia industri (DUDI). Beberapa model sudah diterapkan selama ini, pada tulisan ini diuraikan tentang model-model PBI pada SMK dan menganalisis kekurangan dan kelebihan masing-masing model. Pada tulisan ini akan memberikan rekomendasi model yang paling efektif, efisien, dan praktis digunakan berdasarkan pendapat para ahli dari akademisi, pemerintah, dan DUDI.
