Abstract

Rectifier GR-40 yang digunakan Kandatel Denpasar tersebar diseluruh wilayah Bali. Pelaksanaanoperasi dan pemeliharaan masih sangat tidak efisien, karena dilaksanakan secara manual dan langsung di lokasi.Rectifier GR-40 memiliki keunggulan khususnya dalam proses pengendalian secara komputerisasi. Pengendalianjarak jauh dapat dilakukan melalui dial up modem atau menggunakan jaringan data komputer yang terintegrasisecara intranet untuk mendukung operasional dan pemeliharan sistem catu daya telekomunikasi. Hasil uji coba diSTO Monang-Maning memberikan hasil yang cukup baik, sehingga sistem ini dapat diimplementasikan untukpengelolan operasional dan pemeliharaan Rectifier GR-40 yang tersebar di seluruh Bali yang lebih efisien danefektif.

Abstract

The Kuta Art Market, is a modern market that was recently revitalized in 2023. The building has renewable energy potential of PLTS on the roof area, when this potential can be exploited then the electricity consumption of the Kuta Art Market Building is no longer supplied by conventional power plants (PLN) but will enjoy clean energy of autonomous plants such as PLTS. The aim of this study is to identify the potential for generating electricity on the roof of the Kuta Art Market, determine the capacity of the battery as a reserve source of energy and the value of the investment. The research steps of this thesis calculate the solar energy potential in the area of the Kuta Art Market by using PVsyst software, collect the load profile of the Kuta Art Market. The next step is to compute the capacity of the PLTS - inverter then determine the battery capacity required according to the load profile of the Kuta Art Market and then determines the investment cost to build the solar power plant on the rooftop of the Kuta Art Market as well as to evaluate the potential cost savings that can be achieved by using solar energy as a primary resource. The total roof area of the Kuta Art Market is 780,455 m2 with energy potential of 166,23 kW. Based on the design results, PLTS will be built with a capacity of 61,6 kWp, with total battery capacity 3200 Ah. Total investment of Rp. 1,162,938.563 is required for the construction of PLTS, a payback period of 15 years 8 months, NPV of Rp. 204,439.887,26 and IRR of 8,06%. Based on the values above, it indicates that the PLTS project on the roof of the Kuta Art Market building is feasible to carry out.

Abstract

Penelitian ini membahas pemakaian Jaringan Syaraf Tiruan (JST) Perambatan Balik dan Support Vector Machine (SVM) untuk peramalan kebutuhan beban listrik. Variabel yang dipakai dalam JST dan SVM adalah data beban listrik wilayah Bali. Hasil peramalan memiliki persentase kesalahan rata-rata absolut 5,71% untuk metode JST dan 3,53% untuk metode SVM. Metode JST mempunyai rata-rata eror minimal 0,35% dan maksimal 17,34%. Metode SVM mempunyai rata-rata eror minimal 0,16% dan maksimal 10,53%. Metode SVM memiliki keakuratan lebih baik dibandingkan dengan metode JST.

Abstract

Oka Jamur Bali is one of the oyster mushroom cultivation farmers. Lack of efficiency in regulating temperature and humidity in mushroom barns is an important factor in the growth of mushroom fruiting bodies. This condition requires an innovative solution to regulate and monitor temperature and humidity in the barn area. This research aims to build a prototype using Arduino UNO, ESP32, DHT11, pump and Internet of Things (IoT) technology. The monitoring system design uses Arduino UNO, NodeMCU ESP32, DHT11 and DC pump with 12V voltage. Arduino UNO functions as a control system to manage and control the temperature and humidity parameters of the mushroom barn environment with the DHT11 sensor used to accurately measure temperature and humidity. The combination of NodeMCU ESP32 and Arduino UNO aims for monitoring through the ThingSpeak platform which can be accessed with a smartphone connected to the internet network. Based on the results of the prototype of the automatic temperature and humidity control system, the system is able to measure the environmental conditions of the mushroom barn with humidity measurement results in the range of 79% - 82% and the average temperature during the test reached 29.35°C. The application of the system was able to reduce the temperature by 2.28% with an average temperature of 28.19°C and increase the relative humidity by 6.27% with an average humidity of 81.1% in the mushroom barn area. The results of income between the income generated by using the automatic temperature and humidity control system tool and the income of farmers without using the tool increased by Rp. 16,416.

Abstract

This study explores the potential of citrus peel waste as an electrolyte solution for energy storage in bio-batteries. This research offers an environmentally friendly solution to obtain clean and sustainable energy by utilizing abundant organic waste as raw material. An experimental method was conducted to analyze the ability of electrolyte solutions from citrus fruit peel waste to support bio-battery performance. The results showed that citrus peel waste has significant potential as an electrolyte solution with competitive capabilities in energy storage. The implications of this research include the development of more sustainable alternative energy technologies and the effective use of unused resources, which could be an essential step in achieving global sustainability goals.
