Abstract

Electricity is crucial for supporting development, the economy, and human well-being, thus leading to an increasing demand for electrical energy. Therefore, power plants are planned and constructed to be as economically viable as possible. In line with the principles of affordability, security of supply, and acceptability, to ensure long-term capacity demand and reliability. The reliability of the power plant is measured using the Load of Loss Probability (LOLP) index, which assesses the probability of components functioning satisfactorily to meet demand. The objective of this research is to analyze the reliability of PLTM Orya-Genyem based on the Load of Loss Probability (LOLP) index. The research methodology is qualitative, commencing with the collection of secondary data, followed by LOLP calculations to obtain reliability information. LOLP index for PLTM Orya-GGenyem is 0,4204%, equivalent to 1,5346 days per year, exceeding the PLN standard of 1 day per year. This indicates a lack of reliability in the power plant. Research findings reveal that daily power demand increases by 0,054 MW for every 1% increase in time. Assessment indicates that peak load surge factor is not the cause of the high LOLP value in PLTM Orya-Genyem. Instead, outages are the cause. The assessment shows that there were 72 disturbances of maintenance outages for PLOG-TA-01 and 145 disturbances of system adjustment outages for PLOG-TA-02. Other outages that happen include low water elevation, water storage duration, floods (accumulated debris), transmission work, blackouts, network disturbances, forced outages, planned outages, sedimentation dredging, water drainage, water filling, performance testing, and maintenance during plant operation.

Abstract

The volume of waste will continue to increase with increasing time, population, and economic growth in a city, district, or province. The city of Jayapura, as the center of the economy of the land of Papua, is the same way. The Koya Koso TPA management system for Jayapura City is currently landfill control, where the waste that has been collected at the TPA is stockpiled using layers of soil so that the piles are increasing in number day by day and causing problems including air pollution by methane gas, CO2, and other gases and limited land, thereby reducing the age of TPA Koya Koso Jayapura City. This study aims to determine the potential content of methane gas by modeling it using Landgem software and the potential capacity of electrical energy that can be generated. The results showed that the potential content of methane gas generated from Landgem modeling is 13,134,026 m3/year, or 8,762 tons/year, resulting in a potential capacity of electrical energy of 2,797.22 kW, or 2.8 MW.

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

In competitive sports, various factors influence the outcome of the game. It is believed that the mental toughness dimension is an aspect that contributes greatly to sports achievement in practice. However, unfortunately the condition of mental aspects of teenage athletes in Papua is limited explored. Therefore, the purpose of this community service was to provide assistance for the local government of Papua Province, especially the Sports and Youth Division, in providing information on the mental toughness conditions of adolescent athletes at PPLP/D Papua. The activity was carried out in three stages, namely preparation, implementation, and reporting. The results of the service found that the confidence dimension appeared to be greater than the other dimensions, while the commitment dimension was the dimension with the lowest value.  For other dimensions such as positive cognition, constancy, and control were relatively in the middle. In general, the pattern of mental toughness of Papuan youth athletes appears disproportionate. Thus, mental coaching or training should provide to improve the mental quality of athletes

Abstract

The type of drying device known as a hybrid dryer is a tool that harnesses solar energy and the heat generated by a biomass fuel-powered heat exchanger. This study was conducted to assess the performance of the hybrid dryer by analyzing the parameters of the device itself and the dried material. The research was carried out experimentally using a solar collector and a biomass furnace (as a heat exchanger) to heat the air. The solar collector used consists of 0.35 mm thick, black-painted zinc, coated with 5 mm thick glass, and installed at a 20-degree angle. The heat exchanger pipe used has a diameter of 1.25 inches and is made of galvanized pipe. The tested sample is corn seeds with an initial moisture content of about 24.6%. The experimental results show that in the drying process using a solar dryer, the initial moisture content of 24.8% was successfully reduced to 14% at 5.50 h (rack 1), 6.50 h (rack 2) and 7.00 h (rack 3) with a thermal efficiency of 24.25%. Meanwhile, in the hybrid drying process, the required time is approximately 5.00 h (rack 1), 5.50 h (rack 2) and 6.00 h (rack 3), with a efficiency of the drying equipment used is 21.048±5.690% (hybrid) and 22.706±6.437% (solar).

Abstract

Barapen, a cooking tradition in various indigenous Papuan communities. To date, various social science studies have been conducted to examine social values, business economics, and political economy. While research in the aspects of applied science has yet to be conducted to study the phenomenon of heat transfer by natural convection from hot stones to food in cooking packs, this research was conducted. The purpose of this research is to study the phenomenon of heat transfer by natural convection from hot stones to food in cooking packs. In this study, a square-shaped artificial pool (260 cm x 210 cm x 50 cm) with white batah stone walls was used to cook food in a barapen. On the four walls, a type K thermocouple is inserted to measure the temperature at 3 layers, which will be the object of research. The ingredients are vegetables, sweet potatoes, and chicken meat that has been cut and stoned. As a discussion, the temperature gradient between layers occurs due to the difference in the amount of volumetric heat against time in each layer. The difference in the amount of heat in each layer is due to the difference in the density of the hot vapor trapped in each layer. Thus, it can be said that the cooking of food in Barapen occurs due to natural heat convection.

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%.
