Abstract

Particle Swarm Optimization (PSO) digunakan sebagai alat bantu dalam pemilihan tipe penghantar dalam sebuah sistem distribusi tenaga listrik. Penggunaan PSO dalam penelitian ini telah mengalami perubahan dimana pencarian solusi dilakukan dengan cara memasukkan solusi sebelumnya ke dalam inisialisasi partikel selanjutnya. Berdasarkan simulasi yang dilakukan, solusi terbaik dalam pemilihan penghantar diperoleh pada percobaan keempat. Selanjutnya, penghantar dengan luas penampang yang besar tidak selalu mengakibatkan total biaya sistem yang mahal.

Abstract

The West Java Government has categorized Tasikmalaya be at level 4 (heavy) related to the spread of Covid-19. Community Health Centre of Cibeureum provides health services for the community in Cibeureum District, covering 5 villages. Community Health Centre of Cibeureum provides hospitalization . The average pre-Covid visitasion was 150-200 patients per day, then during the Covid period it decreased to 50-70 patients per day. During the PSBB period, employees of the Community Health Centre of Cibeureum have experienced significant changes in work psycholog, because in addition to having the obligation to serve community, employees were worried about exposure to the Covid-19 virus. There are various kinds of air sterilization methods, including using high pressure : both positive and negative, ultraviolet light, HEPA, and ozone. Apart from being used as an antiseptic, ozone has antiviral, antifungal, and antiprotozoal functions. On the other hand, ozone can also have adverse health effects if used without using standard regulations.

Abstract

The Ar-Ridho PKBM and the Majelis Pemberdayaan Masyarakat (MPM) of the Muhammadiyah Regional Leadership of the city of Tasikmalaya have a large contribution to the community empowerment program in the city of Tasikmalaya. However, the institution has limitations related to training, limited funds, human resources, and other supporting facilities. The problem is related to the lack of Tasikmalaya city people who have skills in the field of technology, so people do not have good skills in dealing with global competition. Therefore, we conduct electronic assembly training activities with a focus on providing electronic assembly skills for the millennial generation. The material presented includes the concept of introducing electronic components, measuring electronics and assembling light sensors on garden lights. With the provision of skills such as this millennial generation is expected to have the basic skills that are used as provisions for entrepreneurship and become productive economically and socially.

Abstract

The electrical power distribution system plays a crucial role in delivering reliable and efficient energy to consumers. One of the main challenges in its operation is the high level of power losses that occur during the distribution process. To address this issue, this study applies a network reconfiguration method by adding an express feeder to the CLDG Tasikmalaya feeder to reduce power losses. The optimization method used is Particle Swarm Optimization (PSO), an algorithm inspired by the social behavior of bird or fish swarms in finding the best solution. Each particle searches for an optimal position (Pbest), and others follow the global best solution (Gbest). Power flow analysis is performed using the Backward Forward Sweep (BFS) method, implemented in MATLAB 2024a and validated with ETAP 19.0.1. The BFS method constructs BIBC and BCBV matrices based on network topology. As a result, power losses were reduced from 450.485 kW to 245.1011 kW after reconfiguration.

Abstract

Power losses in distribution systems are one of the main problems affecting the efficiency of electricity distribution. This study aims to minimize power losses through the installation of express feeders and new load break switches (LBS). The optimization method used to determine the optimal location for installation is the Genetic Algorithm. The Genetic Algorithm and power flow calculations were implemented using MATLAB 2024a software, followed by a validation process comparing the power flow results from MATLAB 2024a with simulation results from ETAP 19.0.1 software. The case study was applied to the CLDG distribution system, comparing the existing conditions with the conditions after optimization. The simulation results for the existing conditions showed a total power loss of 554.109 kW. After applying optimization using the genetic algorithm method to determine the optimal locations for the express feeder and new LBS, power losses were successfully minimized to 308.4 kW. These results demonstrate that installing the express feeder and new LBS using the genetic algorithm method is an effective solution for minimizing power losses in the distribution system.
