Abstract

Electricity is an essential need in the life of Palangka Raya City, and it can be utilized across various sectors such as business, social, industrial, governmental, and household. The increase in population growth in Palangka Raya City has led to a rise in the demand for electricity, necessitating its regulation and efficient distribution to customers. Specifically in the electricity sector, particularly in households, the demand tends to fluctuate due to resistive, inductive, and capacitive loads. This study aims to analyze the load factor, which is the ratio of average load to peak load measured over certain periods such as daily, monthly, or yearly. The first step involves data collection in the household sector of Palangka Raya City, including tariff data and monthly consumption data. The second step involves classifying electrical loads followed by an analysis of load factor accumulation. The third step involves summarizing the results of the accumulation data. From the analysis, it is concluded that the highest load factor values are found in the R.1/450 VA category, with an average of 49.30%, and the highest power factor value is 83.16% compared to other load factor categories. However, tariffs for R.3/6,600 VA and above show a gradual decrease in load factor from February to December.

Abstract

Energy needs in Indonesia are increasing, especially in the realization of electricity consumption which reached 20.18 TWh in July 2020. Using exhaust wind energy from exhaust fans as an alternative source of wind energy is considered quite effective because the characteristics of the wind produced are stable. The method used in This research is quantitative and the purpose of this research is to get the optimal distance from the vertical axis of the savonius wind turbine to the exhaust fan. Setting the distance of the turbine is done by adjusting the position of the wind turbine to the exhaust fan with 4 test distances, namely 10 cm, 20 cm, 30 cm and 50 cm. The results of this study are a distance of 10 cm with a 40 ohm load, the output power is 1.74 watts with an efficiency of 23%, an 80 ohm load, the output power is 1.4 watts with an efficiency of 18%, a 120 ohm load, the output power is 1.215 watts with an efficiency of 16%. , a 160 ohm load produces 0.91 watts of output power with an efficiency of 12%, a 200 ohm load produces 0.91 watts of output power with an efficiency of 12%. distance of 50 cm 40 ohm load output power generated 0.4 watts with 11% efficiency, 80 ohm load output power generated 0.19 watts with 5% efficiency, 120 ohm load output power generated 0 watts with 0% efficiency, 160 ohm load power the output is 0 watts with 0% efficiency, a 200 ohm load produces 0 watts output power with 0% efficiency, so the optimal distance for placing the turbine is 10 cm.

Abstract

The current issue of plastic waste has not yet received appropriate handling, resulting in the inadequate control of plastic waste management practices. Particularly, High Density Polyethylene (HDPE) is still widely encountered. HDPE is a thermoplastic made from petroleum with a melting temperature of 160ºC-240ºC, characterized by being slightly cloudy, transparent, and elastic. This research will conduct testing using a complete randomized design (RAL) factorial analysis with 3 factors to determine the influence of factor A (heating temperature), the influence of factor B (heating time), and the influence of factor C (opening temperature) on flashing defects and warpage defects in HDPE plastic. Based on the testing of flashing defects, the significant influencing factors are factor A (heating temperature), factor B (heating time), factor C (opening temperature), and the interaction of factors AB (heating temperature and heating time). Meanwhile, the significant influencing factors on warpage defects are factor A (heating temperature), factor B (heating time), and the interaction of AB (heating temperature and heating time). Based on this research, the characteristics of HDPE plastic can be determined.

Abstract

The largest source of energy in Indonesia, especially those currently used, mostly still come from non-renewable fossil fuels, which are not environmentally friendly because they produce ???????? 2 gas. Wind energy is a renewable energy source that is environmentally friendly. Apart from using natural wind energy, there is also artificial wind which is the result of wasted energy from exhaust fans as an alternative energy source for wind power plants (PLTB). Wind power that comes from the exhaust fan itself distributes the wind direction, so that the wind energy that can be collected into the turbine is not optimal, so it is necessary to install a wind tunnel. In this study, a trapezoidal wind tunnel model was designed with 2 different lengths, namely 50 cm and 100 cm, which were placed at the end of the fan inlet. This study aims to determine the effect of installing a wind tunnel on the wind speed of the exhaust fan and its effect on the input power of the exhaust fan. The method used in this research is a quantitative method. The research results obtained when the addition of a 50cm blower increased wind speed from 5.8m/s to 12.8m/s, the exhaust fan capacity increased by 119 watts, from 249.2 watts to 368.2 watts, when with a 100 cm fan the wind speed increased to 119 watts. increased from 5.8 m/s to 11.8 m/s, exhaust fan power increased by 70.8 watts, from 249.2 watts to 320 watts.
