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%.

Abstract

This study aims to find out the implementation of the primary high leadership position selection system (JPT) openly in jayapura district government and to parse the factors that hinder its implementation. The method in the study is a descriptive method with a qualitative approach. The data was collected with in-depth interviews with research informants. In addition, it is supported by field observations as well as through documenting. Informants are determined by purposive techniques. Data analysis includes reduction, presentation and drawing conclusions. The results of this study show that the implementation of JPT selection has not been in accordance with the objectives to be achieved. These factors are influenced by the lack of desire and motivation of the apparatus to participate in the selection. Another factor that causes the implementation does not go well is due to the low competitive spirit of the apparatus concerned accompanied by unpreparedness. While from asn from outside Jayapura district is due to the high cost of needs, inadequate aspects of facilities and infrastructure, as well as comfort factors in the current position. While other inhibitory factors indicate that communion to prospective selection participants has not been effective with a narrow scope.

Abstract

The availability of clean water in Wamena City is a target for fulfilling local government development. In the suburbs, a Public Hydrant (HU) in the Sinakma area has been constructed to meet the community's clean water needs. The fulfillment of clean water needs for network distribution has also existed in Wamena City which was built in 2016 sourced from the Walesi River with the construction of a reservoir in the Napua area, but the distribution was disrupted because the Napua Intake was damaged by landslides. However, due to the condition of landslides and logging that are quite a lot in the upstream area, currently the intake does not function and affects the distribution of water in Wamena City. In 2023, an Intake and several reservoirs with the Wasi River water source in Walesi District have also been built, which are expected to meet the city's water needs. But in reality, the building has not been able to meet the needs of clean water because it cannot capture the flow of water properly.
