Abstract

Electricity consumption is an important factor in driving economic growth. Increasing economic growth will increase electricity consumption, and vice versa. The effect of the growth of electricity consumption on economic growth in Papua Province is a goal to be known through this research. To achieve this goal, secondary data for 2012–2022, sourced from the Central Bureau of Statistics for Papua Province and PT. PLN (Persero) Papua and West Papua regions, are processed using a quantitative approach and multiple regression analysis model. This secondary data includes investment value, regional expenditure, the human development index, and population, which is an independent variable. While the electricity consumption data is a dependent variable. The results of the study show that simultaneously, all independent variables have a significant effect on the dependent variable. The value of investment, regional expenditures, and the human development index have a positive but not significant effect on increasing electricity consumption. While the population has a positive and significant influence on increasing electricity consumption.

Abstract

This study aims to determine whether the islanding-based defense scheme at the Orya hydropower plant can effectively maintain the stability of the Jayapura radial power system during major disturbances. The system was modeled and tested in DIgSILENT PowerFactory under several outage scenarios, with a focus on the separation of the Orya–Sentani–Skyline corridor. The simulation indicates that maintaining post-disturbance operation within the nominal frequency of around 50 Hz and voltage variation of ±5% requires shedding 19.89 MW of load from selected feeders. After the scheme is activated, the islanded Orya subsystem settles at approximately 50.15 Hz, while the remaining grid stabilizes near 50.0 Hz—both within regulatory limits. These findings suggest that a combined load-shedding and islanding strategy can reduce the risk of cascading failures in Jayapura and may offer a practical template for other radial systems with limited redundancy.

Abstract

The use of wind energy as one of the producers of electrical energy is done by converting mechanical energy into electrical energy from wind turbines, one of which is the savonius wind turbine. Savonius wind turbines in use are able to work at low wind speeds. This study aims to evaluate the potential of wind energy that can be generated by optimization in savonius wind turbines by measuring the power generated by varying the gap distance between Balde and turbine shafts and analyzing the most optimal power as a source of power generation on the coast of Sarmi Regency, Papua Province. The analysis method in this study is field surveys, wind speed measurements, power optimization, BHP and tool efficiency carried out with variations in the distance between the blade and turbine shaft, namely 5 cm, 10 cm and 15 cm. The results of this study stated that the most optimal and stable results on the power generated by the turbine as well as the BHP value and the best tool efficiency were a distance variation of 15 cm with an average power value produced (P0) of 15.55 Watts, an average BHP value of 0.56 Watts and an average efficiency value of 7.59%.
