Abstract

The surge in positive cases of Covid-19 in Indonesia has increased the demand for medicines and vitamins. As a result, many residents visited the village health center, pharmacies, and drugstores to buy medicine or vitamins to boost their body's immunity during a pandemic. health protocols that limit room capacity result in queues of buyers snaking which can lead to the potential for new infections. The World Health Organization (WHO) itself urges people to implement contactless payments, by using e-money or using electronic payments and avoiding touching touchless devices. This research is a continuation of the activity plan for Community Service at the Jatimelati village health center Pondok Melati Bekasi. Machines providing medicines that accommodate contactless and face-to-face contact with officers are deemed necessary to meet the needs of medicines and vitamins as a complement to machines providing medicines and vitamins so that people can get them more easily during and after the pandemic. In this study, this drug supply machine is equipped with a payment system using a balanced RFID card such as e-money and is also integrated with the website to facilitate monitoring of drug stock availability.

Abstract

Nowadays, energy sources in the world at the end until now tends to be filled using fossil fuels. It is estimated that the world energy consumption until 2025 is still dominated by fossil fuels, namely oil, natural gas and coal. The Ministry of Energy and Mineral Resources said that petroleum dominates 54% of energy use in Indonesia. One way to overcome the use of fossil energy sources is to replace them with renewable energy especially photovoltaic. Therefore, this paper presents solar charge system using Buck Converter PID Controller for Spotlight load. Buck Converter with PID Controller is used to produce a smaller and more stable output voltage from solar panels of 14.4 Volts for charging the battery. The PID parameter values ??obtained after performing calculations using the Analytic Tuning method and tuning are Kp = 0.0307, ??Ki = 58.20 and Kd = 0.000263. The expected result of this research is to design and implement a solar charge controller as a producer of electrical energy from environmentally friendly energy.

Abstract

Keandalan jaringan tenaga listrik merupakan tuntutan masyarakat modern saat ini. Berbagai program peningkatan keandalan terus dilakukan antara lain dengan inspeksi dan pemeliharaan gardu distribusi. Inspeksi dilaksanakan secara periodik untuk mengetahui kondisi peralatan berfungsi dengan baik. Namun demikian masih terdapat gangguan yang disebabkan oleh korona pada kubikel 20 kV. Dampaknya yaitu terhentinya pasokan listrik ke pelanggan dan berpotensi menimbulkan kerusakan kubikel itu sendiri. Penelitian ini terkait dengan perancangan prototipe alat pendeteksi korona sebagai proteksi kubikel keluaran 20 kV. Tujuan penelitian adalah menghasilkan sebuah prototipe alat pendeteksi korona sebagai proteksi kubikel keluaran 20 kV pelanggan tegangan menengah serta mengetahui pengaruh suhu dan kelembapan terhadap jumlah O3 yang dihasilkan, agar dapat diimplementasikan sebagai proteksi kubikel keluaran 20 kV pelanggan tegangan menengah. Metode yang dilakukan meliputi analisa kebutuhan, perencanaan desain, perakitan dan pengujian sistem. Prototipe alat berfungsi untuk mengukur konsentrasi ozon (O3), suhu dan kelembapan pada kubikel. Parameter uji meliputi pengaruh kelembapan dan besar tegangan terhadap pembentukan konsentrasi O3. Uji pengaruh kelembapan menghasilkan tingkat kelembapan 99% RH jumlah O3 sebesar 241,0 ppb, kelembapan 95% RH jumlah O3 sebesar 106,2 ppb dan 90% RH jumlah O3 sebesar 78,55 ppb. Uji pengaruh tegangan menghasilkan nilai tegangan 14 V jumlah O3 sebesar 225,36 ppb dan tegangan 12 V jumlah O3 sebesar 106,63 ppb. Prototipe alat pendeteksi korona dapat diimplementasikan sebagai proteksi kubikel keluaran 20 kV pelanggan tegangan menengah.

Abstract

An electric vehicle charging station (EV charging station) is an infrastructure designed to charge electricity for electric vehicles. However, most EV charging stations still rely on fossil energy sources. Innovation is needed to overcome this problem. One of them is through the use of solar panels. Using solar panels on the CBMS turns it into a clean and environmentally friendly energy source. However, environmental factors such as weather significantly affect the energy conversion produced by solar panels. Panels that are covered by trees and tall buildings cause partial shading conditions. Partial shading conditions can result in a direct decrease in PV output power. To overcome this, output power optimization using a DC-DC converter is required. The MPPT boost converter system with a modified P&O method is designed to maximize the output power of solar panels when partial shading occurs. The test results show that the developed system can maximize the output power of solar panels in partial shading conditions with an average power increase of 8.13 and an efficiency of 91%. This method can reduce the negative impact of changes in light intensity, keep the system close to the maximum power point, and improve the efficiency of charging electric vehicles at SPKL during unstable weather conditions. However, the modified P&O method is less effective in maximizing the output power in standard solar panels. This research does not address the effectiveness of solar panels concerning temperature, humidity, and dust.
