Abstract

Progammable Logic Controller (PLC) is a user friendly, microprocessor-based equipment that contains control functions of various types and levels of complexity. The control system is designed to be able to monitor the value of the power factor to remain stable and can determine the indication of early damage to the capacitor bank. In this research, an automatic control system is designed that can turn on the capacitor bank when the power factor value ≤ 0.95 and turn off the capacitor bank when the power factor value ≥1. HMI can provide data indication of early breakdown of capacitor banks based on the current value of each capacitor. This system utilizes PLC GE, and CE Digital Transducer so that the condition of the capacitor bank can be known in case of damage and decreased efficiency. Based on the test, when the power factor value is 0.95, the program will turn on the capacitor bank to meet the set point value of 0.95 and turn on the alarm indication that the power factor value is not sufficient, when the power factor value exceeds ≥1, the program will turn off the capacitor bank that works longer. The HMI system is able to provide data to perform preventive maintenance activities on a regular basis in order to maintain the efficiency and reliability of capacitor banks.

Abstract

Peralatan tegangan tinggi memegang peranan terpenting dalam sistem tenaga listrik. Untuk menjaga peralatan dalam kondisi operasi yang optimal diperlukan sistem isolasi peralatan yang baik. Isolasi cair banyak digunakan dibandingkan isolasi gas khususnya pada transformator daya. Hal ini disebabkan memiliki tingkat massa jenis yang tinggi, dimana nilainya 1000 kali daripada isolasi gas. Penggunaan minyak nabati dapat menjadi alternatif sebagai pengganti atau campuran minyak bumi karena minyak nabati merupakan sumber daya alam yang terbaharukan sehingga ketersediaannya terjamin serta ramah lingkungan. Pada penelitian ini dilakukan analisis karakteristik kekuatan dielektrik minyak metil ester bunga matahari dengan campuran minyak mineral sebanyak lima sampel sebagai bahan alternatif isolasi cair pada transformator.  Metode pengukuran tegangan tembus berdasarkan standarisasi yang mengacu kepada IEC 60156-95, dimana pengukuran menggunakan elektroda jenis bola-bola dengan jarak elektroda 2.5 mm pada empat kondisi temperatur. Berdasarkan standar SPLN 49-1-1982 minyak metil ester biji bunga matahari memenuhi standar tegangan tembus minyak isolasi baru yaitu ≥30 kV/2.5mm atau sama dengan kekuatan dielektrik sebesar ≥120 kV/cm. Dimana sampel D merupakan campuran antara 30% minyak metil ester biji bunga matahari dengan 70% minyak mineral yang memiliki kekuatan dielektrik tertinggi sebesar 290.74 kV/cm pada suhu uji 800C.

Abstract

Desa Timbang Jaya memiliki sumberdaya air yang menjadi potensi untuk dikembangkan menjadi objek wisata. Selain itu Pemerintahan Desa juga memiliki komitmen untuk menjadikan desanya menjadi desa yang mandiri. Mandiri dalam arti tidak hanya sekedar melakukan pembangunan desa dengan mengandalkan dana desa, namun juga dapat menciptakan sumber pendapatan melalui usaha sendiri. Usaha ini nantinya diharapkan tidak hanya sebagai penambah kas desa, namun juga dapat meningkatkan pendapatan masyarakat desa. Hal yang menjadi permasalahan pada Desa Timbang Jaya adalah kebutuhan kerjasama untuk menata potensi sumberdaya yang dimiliki. Desa Timbang Jaya memiliki sumberdaya air yang potensial namun belum dapat dikelola untuk menjadi sumber pendapatan tambahan desa dan masyarakat. Metode yang diterapkan pada kegiatan pengabdian yaitu dengan melakukan diskusi bersama masyarakat untuk memperoleh alternatif kegiatan serta mengimplementasikan kegiatan tersebut dalam bentuk penataan objek wisata. Dari hasil diskusi dengan masyarakat disepakati kegiatan yang akan dilakukan yaitu menata objek wisata air dengan melakukan pengecatan pada dinding saluran irigasi primer dan menebarkan benih ikan pada saluran tersebut untuk menjadi daya tarik bagi pengunjung. Kegiatan telah dilaksanakan sesuai rencana dan telah memberikan solusi atas harapan mitra dengan melakukan penataan objek wisata air.

Abstract

The surge in adoption of electric vehicles (EVs) within the transportation sector can be attributed to the growing interest in sustainable transportation initiatives. It is imperative to position electric vehicle charging stations (EVCS) strategically and distribute generations (DGs) to mitigate the effects of electric vehicle loads. This research employs the whale optimization algorithm (WOA) to optimize the placement of EVCS and DGs alongside network reconfiguration. The backward-forward sweep (BFS) power flow technique is utilized to compute load flow under varying load conditions. The primary objective of this investigation is to minimize power losses and enhance the voltage profile within the system. The proposed approach was tested on IEEE-33 and 69 bus systems and compared with particle swarm optimization (PSO) and genetic algorithm (GA) techniques. The simulation outcomes affirm the effectiveness of whale optimization algorithm in determining that integrating 3 EVCS with 3 DGs yields optimal outcomes following network reconfiguration, resulting in a 56.22% decrease in power losses for the IEEE-33 bus system and a 76.13% reduction for the IEEE-69 bus system. The simulation results indicate that the proposed approach enhances system performance across all metrics, showcasing the superior performance of WOA compared to PSO and GA in accomplishing set objectives.

Abstract

Dairi Regency is the largest durian fruit producer in North Sumatra Province with a production of 23 thousand tons per year. One of the largest durian-producing villages in Dairi Regency is Sungai Raya Village. The estimated volume of durian skin waste produced in North Sumatra is 332,712 tons of durian skin per year, this can be seen from the large amount of durian skin waste that accumulates on the side of the road, in rivers, and farmers' gardens. Given the large volume of durian skin, it takes an effort to process durian skin waste into compost that can be used by farmers and can improve the welfare of farmers. The solution for processing durian skin is to build a community-based processing unit for processing durian skin into community-based compost by involving farmer groups. To carry out efforts to manage durian skin waste, a simple tool is needed that functions as a durian skin chopper as a basic material for compost. From the results of the durian skin counting and the dissemination of fertilizer making, farmer groups and the community have been able to make fertilizer from durian skin so that it can increase the income of the population.

Abstract

The Covid-19 pandemic is believed to be a turning point for changes in tourism and the design of creative economy business models, including in Indonesia. Through the Ministry of Tourism and Creative Economy, the government prepares various policy directions and strategies in tourism promotion programs during the pandemic and post-pandemic in Indonesia. Sidamanik District is one of the sub-districts in the Simalungun Regency, North Sumatra Province, which has considerable natural potential, namely natural potential in the form of landscapes such as the Bah Butong Sidamanik tea garden, Bah Manik baths, and Bah Biak Waterfall. Bah Biak Waterfall has its uniqueness. Bah Biak Waterfall has a height of approximately 20 meters which immediately falls into the rocks and a swimming pool provided by the manager. The current condition experienced is the lack of visitors who come to tourist objects due to the lack of marketing and information disseminated to the broader community, especially during a pandemic like today. Along with technological advances, the development of promotional media began to shift to digital media, one of which was video. Therefore, through community service, which is one of the tri dharma of higher education and to support Strategy 7 of the Ministry of Tourism and Creative Economy: Utilization of technology to support tourism marketing and the creative economy, our service team proposes making tourism promotion videos through video/ Digital Marketing of Bah Biak Tourism Object in Bah Biak Village, Sidamanik District. Through this video, we hope to positively impact tourist destinations, including a significant increase in the tourism sector.

Abstract

The manufacture of Liquid Organic Fertilizer (LOF) has been carried out with simple methods and equipment in the Semangat Village, Merdeka District, Karo Regency. LOF is made by utilizing waste produced by farmers at the time of post-harvest vegetables such as cabbage, cabbage, carrot leaves and other vegetables. These vegetables can be used because 90% is a liquid. The chopped cabbage waste is mixed with cow rumen and fermented for two weeks, the resulting leachate is fermented again by adding coconut water and LOF is produced which is ready to be used by farmers. With this LOF, farmers can be helped in reducing chemical fertilizers which are quite expensive, so that the costs needed by farmers are less and LOF can increase nutrients in the soil.
