Abstract

Ditinjau terhadap percepatan puncak gempa di permukaan bumi, maka lebih dari setengah wilayah Indonesia memiliki kekuatan gempa sedang sampai tinggi dengan kedalaman pusat gempa dari dangkal sampai sangat dalam. Jika lokasinya yang rawan terhadap gempa, maka struktur bangunan di Indonesia harus mempertimbangkan besarnya kekuatan gempa pada perencanaan konstruksi bangunan. Besarnya energi gempa yang terjadi menggunakan rumus Log E = 11,4 + 1,5 R. Selanjutnya dapat dihitung hubungan Magnitudo dan Frekuensi gempa yang tejadi. Pengaruh gempa dipermukaaan tanah tidak hanya di tentukan oleh besar energi yang dilepaskan akan tetapi kedalaman atau jarak sumber gempa. Untuk menentukan pusat gempa (epicentrum) tidaklah sederhana, untuk itu digunakan parameter-parameter yang telah disederhanakan dengan data seismograf. Berdasarkan uraian latar belakang masalah tersebut penulis menarik judul Analisis Penentuan Letak Epicentrum Gempa Dan Dampaknya Terhadap Konstruksi dengan hasil penelitian semakin dekat permukaan tanah dari dasar batuan, kecepatan gelombang gempa yang datang dari bawah akan berkurang sedangkan amplitudo vibrasinya akan membesar. Meskipun demikian dampak kejadian ini akan efektif pada tanah dengan ketebalan lebih dari 10 m. Semakin dalam batuan berada maka elastisitas batuan semakin tinggi, hal ini memungkinkan pada kedalaman besar dapat menyimpan potensial besar yang suatu saat akan terlepas menjadi gempa.

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

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

The chili farming center in Lubuk Cuik Village, Batu Bara Regency, is the second largest after Karo Regency, with a total area of 1,092 hectares. The challenges faced by members of the Berkah Abadi Jaya Cooperative include declining soil fertility, low productivity, and high fertilizer costs, affecting farmers' profits. To address these issues, training on compost production and cooperative management was provided. Initially, members were trained to make compost from agricultural waste (leaves) and animal manure (KOHE). These materials were sprayed with Yanysis technology to accelerate the composting process. Participants were also trained to operate compost shredders to reduce leaf size. Solid organic fertilizer (POP), made from a mixture of leaf compost, KOHE, and humus soil, was applied to a chili plot and compared to chemical fertilizers. The results showed that cooperative members were able to independently produce POP. The composting time was reduced from 1-3 months to 2 weeks, while the plant height, number of leaves, and chili fruits were similar. Additionally, cooperative members gained a good understanding of cooperative business management, decision-making, and business diversification.
