Abstract

This study aims to see how effective the type C passive filter is in reducing harmonic currents generated by the electrodynamometer induction motor trainer. The method used in this study is to model a C-type passive filter and simulate it with computer software. The type C passive filter modeling is designed to reduce harmonics in the thirty-fifth order. From the observation results, it was found that the thirty-fifth order harmonic current was 1.5% while the IEEE 519-2014 standard limits the thirty-fifth order harmonic current to 1.0%, which has exceeded the permitted standard. After the simulation, the type C passive filter successfully reduced the existing harmonics so that the harmonic content was 0.95%. From the results of this simulation, it can be concluded that the type C passive filter successfully reduced the harmonic content in the thirty-fifth order to 36.29%. This harmonic reduction has also been below the maximum value permitted by the IEEE 519 – 2014 standard at the thirty-fifth order so that the passive filter is effective in reducing the thirty-fifth harmonic produced by the electrodynamometer induction motor trainer.

Abstract

Penelitian ini bertujuan untuk menganalisis kebutuhan dalam pengembangan modul praktikum monitoring panel kendali industri berbasis Internet of Things (IoT). Latar belakang penelitian ini adalah kesenjangan antara praktik pembelajaran di laboratorium pendidikan tinggi dengan tuntutan keterampilan teknologi industri 4.0. Penelitian menggunakan pendekatan deskriptif kualitatif dengan teknik pengumpulan data melalui observasi lapangan, wawancara semi-terstruktur terhadap dosen, mahasiswa, dan praktisi industri, serta analisis dokumen pembelajaran seperti silabus, RPS, dan modul ajar. Hasil penelitian menunjukkan bahwa fasilitas praktikum umumnya masih konvensional dan belum terintegrasi dengan sistem monitoring digital atau perangkat berbasis IoT. Praktisi industri menekankan pentingnya penguasaan sistem monitoring jarak jauh dan keterampilan integrasi perangkat lunak dan keras sebagai kompetensi dasar di dunia kerja. Analisis dokumen juga menunjukkan belum terintegrasinya materi IoT secara eksplisit dalam kurikulum dan rencana pembelajaran. Berdasarkan hasil tersebut, dapat disimpulkan bahwa pengembangan modul praktikum berbasis IoT sangat dibutuhkan untuk menjembatani kesenjangan antara dunia pendidikan dan industri. Modul ini diharapkan dapat mendukung pembelajaran yang lebih aplikatif, adaptif terhadap perkembangan teknologi, serta membekali mahasiswa dengan keterampilan yang relevan di era digitalisasi industri.

Abstract

Industry is one of the economic sectors that plays a role in processing environmental resources into products with higher utility values. This process includes design activities, industrial engineering, and service provision. Matra Abadi Workshop, a manufacturing industry that in its operations produces harmonic currents in the electric power system network, especially in low-order harmonics such as 3rd, 5th, 7th, 9th, and 11th. To reduce the negative impact of harmonics on the power system, the use of passive harmonic filters is required. Among the types of filters used, single tuned filters are a common choice because of their simple construction and effectiveness in reducing certain order harmonics that exceed the IEEE 512–2014 standard limits. This study discusses the implementation of both types of filters in a manufacturing industry environment. The harmonic reduction process is carried out through filter design and testing using Matlab/Simulink software-based simulations. The simulation results show that after the application of passive filters, the harmonic current levels in all load configurations were successfully suppressed to within the IEEE 512–2014 standard limits. The reduction in Total Harmonic Distortion (THDi) after the application of the single tuned filter was recorded in the range of 17.86% to 11.06%. In addition, there was an increase in the power factor from 0.68 before the filter was installed to 0.91 after the installation, which indicates an improvement in the overall power system performance.

Abstract

This activity describes the planning, installation, and evaluation of the implementation of a Solar Power Generation System (PLTS) at the Istiqomah Community Reading Park, Terjun Village, Medan Marelan District. The objectives of the activity are (1) to provide a reliable independent power supply for lighting and auxiliary learning devices at the reading park, (2) to increase the managers’ capabilities in operating and maintaining the PLTS, and (3) to assess the technical and social sustainability impacts after installation. Methods used include an energy needs and peak load survey, design of an off-grid system based on the survey results, installation of main components (PV panels, controller, batteries, inverter), and operational and maintenance training for the reading park managers. Evaluation was conducted through measurements of energy availability (hours of lighting operation), reduction in consumption from the PLN grid (kWh), and user satisfaction questionnaires. Based on the needs survey, the reading park’s electricity use is mostly allocated to lighting, fans, and computer operation. Results show that the installed PLTS successfully supplied 95% of the reading park’s daily electricity needs, directly resulting in monthly electricity savings of up to Rp 250.000,00. The results indicate that the designed PLTS meets lighting and light electronic device needs during the reading park’s operating hours, reduces dependence on external supply, and increases community participation in literacy activities, making it an effective strategy for achieving energy independence.

Abstract

Satu dari beberapa peralatan Flexible AC Transmossion System (FACTS) yang berfungsi untuk mengatur daya reaktif dan memperbaiki faktor daya adalah Static Var Compensator (SVC). Penggunaan Thyristor Controlled Reactor (TCR) pada SVC akan mempengaruhi kualitas daya yaitu distorsi harmonik. Pada penelitian ini bertujuan untuk memodelkan dan menganalisis harmonik yang dihasilkan SVC untuk jenis 1 TCR ditambah 3 Thyristor Switch Capacitor (TSC), serta mengevaluasi efektifitas filter pasif single tuned dalam mereduksi THD sesuai dengan standar IEEE 519 – 2014. Pemodelan dilakukan pada sistem tiga fasa menggunakan perangkat lunak Matlab/Simulink. analisis harmonik dilakukan dengan menggunakan Fast Fourier Transform (FFT) digunakan untuk mengidentifikasi harmonik dominan dan menghitung THD. Dari hasil simulasi menunjukkan bahwa sebelum pemasangan filter, harmonik individual masih seseuai dengan batas standar tetapi THD mencapai 13,89%. Nilai ini menunjukkan bahwa THD melebihi ambang batas 5% untuk sistem distribusi tegangan menengah. Setelah dipasang filter harmonik single tuned yang disetel pada orde ke-5 maka diperoleh nilai THD menurun drastis menjadi 0,90%. Sebagai kesimpulan bahwa filter single tuned terbukti efektif dalam mereduksi distorsi harmonik SVC hingga batas standar kualitas daya yang berlaku.
