Abstract

The increasing population and the growth of the industrial world, offices, hotels, and modern markets must be directly proportional to Indonesia's availability of electrical energy. The availability of sufficient electrical energy can affect the quality of life of the people and foster investor confidence in our country. Studies on the prediction (estimation) of peak electrical loads in electricity in Indonesia can be carried out using the Artificial Neural Network (ANN) method. The estimation of electricity load for the next 5 years is strongly influenced by several parameters, including population growth and peak load data of 150 kV GITET, Kesugihan Cilacap. This study took population data and peak load data at GITET 150 KV Kesugihan Cilacap in the past 5 years. The data used in this study were actual data, starting from 2015 to 2019. To display the results of the estimated electrical load on the 150 kV GITET transformer, the authors used the artificial neural network method. The peak electrical loads estimation results using artificial neural networks for electricity loads in the next 5 years, to wit from 2020 - 2024. The estimated peak load in Lomanis District is20.0311 MW, 24.443 MW, 19.9707 MW, 19.9705 MW and 19, 9705 MW. In Gombong District, the estimated peak load is 57,398 MW, 57,472 MW, 57,476 MW, 57,474 MW, and 57,479 MW.

Abstract

Universitas Muhammadiyah Purwokerto has numerous buildings, including the rectorate and the 55.27-meter-tall K.H. A.R. Fachruddin building, that could be struck by lightning and as a result, it require an efficient lightning arrester system (SPP). This study aims to evaluate the building's lightning safety level in compliance with SNI 03-7015-2004, the General Regulations for Lightning Protection Installation (PUIPP), and the building's lightning arrester system's state. Direct measurements of building structures, lightning arrester system components, lightning arrester conditions, and soil resistance are employed to collect research data using the observational approach. The study calculates the degree of protection in structures in accordance with the General Regulations for Lightning Protection Installation (PUIPP) standards and determines the value of the protection range using SNI 03-7015-2004. Both the KH AR Fachruddin building and the rectorate building have an R index of 14, which means that they both desperately need an efficient lightning arrester. The Rector building's system is only 75% effective, compared to 91% in the KH AR Fachruddin building.
