Abstract

This research was conducted to predict the effect of COVID-19 to the total of energy produced by the amount of electricity per capita. The amount of energy produced has the property of being an independent variable or can be affected and electricity consumption per capita has the nature of being an independent or influential variable. This research examines the effect of per capita electricity consumption on the total amount of energy produced in the Lampung region. The research was conducted using regression and correlation experiments. Regression research proves that there is no relationship between electricity consumption per capita and the total amount of energy produced. In contrast, in the linear correlation experiment, there is a correlation between electricity consumption per capita and the total amount of energy produced.

Abstract

This study aims to analyze the resonance frequency of the Tesla Coil module based on experiments and theoretical calculations, and provide recommendations for improving the resonance design. The theoretical resonance frequency is calculated at 130.1 kHz, while experimental measurements show a deviation of 5–10%, caused by component tolerance, passive losses, and parasitic effects. Power transfer efficiency increases with input voltage, reaching 82% at 24 V. Analysis using a Quality Factor (Q) of 21.6 and a primary-secondary inductance ratio of 13.6:1 shows good resonance performance but can still be improved. Recommendations for improvement include selecting components with lower tolerances, adjusting capacitance and inductance values, and optimizing PCB design to reduce parasitic effects. The results of this study are expected to be a reference in the development of more efficient and accurate Tesla Coil modules.
