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

This study aims to analyze the nature of chemical content, analyze abrasion value and optimum asphalt content using local Kinang Jingkion as road pavement material. In this study, XRF and XRD testing methods were used to determine the chemical content of Kinang Jingkion local material, then testing the characteristics of rough aggregate to determine the abrasion value, testing fine aggregate characteristics, and testing asphalt pen 60/70 and marshall test to determine the optimum asphalt content (KAO). The tests obtained the results of comparative data analysis between laboratory tests and literature standards that meet the eligibility requirements. The results showed that: First, the results of XRF and XRD analysis on Wilihingke samples, 0.15 mm granules, 2.36 mm granules, and Kinang Holuwon found that all chemical elements contained in the four samples were solid metal inorganic chemical elements. The results of this analysis prove that the four samples, which are fine aggregates and coarse aggregates, do not contain organic substances. Where the results of this analysis are by the requirements of aggregates which are one of the components in the concrete mixture, where the aggregates used must meet certain conditions, one of which must not contain excess organic matter because it can undergo decay by bacteria using dissolved oxygen; Second, from the test results obtained, the aggregate wear value (abrasion) was 32.69%; Third, based on the test results, the value of the Marshall parameter with Optimum Asphalt Content (KAO) obtained a value of 6.125%.

Abstract

This research aims to analyze the California Bearing Ratio (CBR) and Unconfined Compressive Strength Test (UCS) values as road foundation layers using local materials, namely Kinang Jingkion. The soil and Kinang Jingkion materials for the study were taken from the Apalapsili quarry in Yalimo Regency. Additionally, the additive or soil stabilizer used was matos obtained from the testing of soil characteristics, including sieve analysis or gradation, Standard Proctor Test for light density, and liquid limit test. After testing, it was found that the soil from the Apalapsili quarry is granular soil and can be categorized as A-1-a according to SNI 03-6797-2002. Subsequent testing involved CBR and UCS testing on Mix Designs made of soil and cement with concentrations of 4%, 6%, and 8%. Next, additional Mix Designs were created with compositions of Kinang Jingkion, soil, cement at 4%, 6%, and 8%. Further Mix Designs included compositions of Kinang Jingkion, soil, matos at 2%, and cement at 4%, 6%, and 8%. From the UCS testing results, Mix Designs with soil and cement concentrations of 4% and 6% did not meet the compressive strength criteria, with compressive strength values of 9.26 Kg/Cm² and 17.4 Kg/Cm² respectively. According to SNI 6887-2012, the compressive strength value after 7 days of immersion should be within 25-35 Kg/Cm², while other Mix Designs met the criteria of SNI 6887-2012. CBR testing also utilized the same Mix Designs, and the highest CBR result was obtained from the Mix Design with compositions of Kinang Jingkion, soil, cement at 8%, and matos at 2%, with a CBR value of 112%. According to the 2018 Revised General Specifications, a CBR value of 112% indicates a Class A Foundation Layer.

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.
