Abstract

Today, especially among industrialized and developing nations, the usage of renewable energy sources is growing in popularity as a means of supplying energy needs. One of the renewable energy sources that is now being heavily exploited in Indonesia is the potential of water that may be used as a source of electrical energy by establishing a hydroelectric power plant (PLTA). One of the turbines that is frequently used in hydropower plants as a part that may transform water's kinetic energy into mechanical energy is the Pelton turbine. There is not a lot of literature on the design of Pelton turbine buckets. In order to determine the most ideal bucket dimensions that can be used with Pelton turbines, this study presents the conceptual and experimental components of the design and analysis of Pelton turbines based on bucket variations. AutoCAD was used to model the bucket and Pelton turbine, and ANSYS Fluent was used to perform the simulation so that results could be analyzed later. By comparing the simulated data of the blade variants 1 and 2, the ideal blade dimension variation is identified by the blade simulation of variant 1. The blade variation 2 with average torque of 5.859 Nm, average angular velocity of 40.822 rad/s, and average power of 242,970 watts is the most ideal blade. With an average torque of 4,735 Nm, an average corner speed of 40,404 rad/s, and an average power of 196,794 W, the blade 3 model has lower values

Abstract

The aim of this research was to investigate the influence of catalyst on the flash point, viscosity, density, and iodine value of biodiesel. The raw material used in biodiesel production was waste cooking oil. The transesterification process was employed by reacting the catalyst and methanol, followed by mixing them with the waste cooking oil simultaneously. The catalyst concentration variations used in this study were 0.25% and 0.5%. The resulting transesterification mixture was left to settle for approximately 10 minutes. The biodiesel and glycerol were separated after settling, and the biodiesel was washed with distilled water at a temperature of 50°C and then evaporated at 100°C. The flash point test results for catalyst concentrations of 0.25% and 0.5% were 58°C and 48.5°C, respectively. The viscosity test results for catalyst concentrations of 0.25% and 0.5% were 4.567 x 10-6 m2/s and 4.625 x 10-6 m2/s, respectively. The density test results for catalyst concentrations of 0.25% and 0.5% were 889 kg/m3 and 888.3 kg/m3, respectively. The iodine value test results for catalyst concentrations of 0.25% and 0.5% were 112.2 g I2/100g and 114 g I2/100g, respectively. Based on the test data, the flash point, viscosity, density, and iodine value were obtained. The test results indicated that the flash point values from both experiments did not meet the biodiesel quality standards. However, the viscosity and density test results from both experiments met the biodiesel quality standards and were suitable for use. Regarding the iodine value test, the characteristics of the biodiesel from both experiments did not fully meet the biodiesel standard, although the results obtained were not significantly different from the quality standards set by the Ministry of Energy and Mineral Resources

Abstract

A hydroelectric power plant (PLTA) uses the flow of water as a source of energy. Evaluating the output of hydropower facilities, including the optimal height of the waterfall, turbine torque, electrical power, generator power, and generated efficiency, was the aim of the study. This study intends to investigate the power, torque, and efficiency that may be produced by a hydroelectric power plant with a whirlpool-type turbine, as well as how the height of falling water influences the operation of the plant. The experiment in this study measures three different waterfall heights with five different blade configurations. The study on the hydropower prototype involved three trials that collected data on torque, power, efficiency, waterfall height, and water discharge. The PLTA Prototype's best potential head in Test 3 was determined to be 0.01143, with a height of 0.67 meters, no sluice, and a diameter of 0.0625 meters. The lowest water outflow was discovered at a head of 0.55 meters with a water debit of 0.01036. The third attempt, which featured a sluice opening with a diameter of 0.0625 meters and a height of 0.67 meters (head), used the most water power in the experiment. The testing yielded the following results: 75.13 watts of water power, 5.16 watts of generator power, 0.233 N.m. of torque, 2.63 watts of turbine power with a generator load 3.73 watts without one, and 6.87% efficiency. Data gathered from the hydropower prototype's operation can be used to construct testing instruments for use in laboratories

Abstract

The scarcity of fossil fuels, environmental concerns, and the sharp rise in fossil fuel prices have driven scientists to search for alternative fuels. The characteristics of biodiesel have made the quest for high-quality biodiesel production particularly appealing. The use of waste cooking oil is a key component in reducing biodiesel production costs by 60-90%. Researchers have employed various types of transesterification reactions with both homogeneous and heterogeneous catalysts for biodiesel production; in this study, a 0.5% NaOH catalyst is used. The objectives of this study are to produce biodiesel fuel based on waste cooking oil, evaluate the impact of reaction time variation on the oxidation value and acid value of biodiesel produced from waste cooking oil, and statistically test the effects of reaction time on the oxidation value and acid value of biodiesel produced from waste cooking oil using analysis of variance (ANOVA). The optimum yield was obtained at a reaction time of 90 minutes, achieving 97%. The results for acid number and oxidation value for various reaction times complied with ASTM, EN, and SNI standards. Linear regression analysis of ANOVA for the acid number concluded that the P-value t3 is 0.399, which is greater than Alpha = 0.05, indicating that the variation in reaction time does not have a significant effect on the acid number. Linear regression analysis of ANOVA for the oxidation number concluded that the P-value t3 is less than Alpha (0.047 < 0.05), indicating that reaction time has a significant effect on the oxidation number.

Abstract

The ever-increasing global energy demand necessitates the development of environmentally friendly and sustainable alternative fuels. Biodiesel is a potential solution, mainly when produced from used cooking oil through the transesterification process. This study aims to evaluate the effect of reaction time on the calorific value of biodiesel using the linear regression method. The calorific value was chosen as the primary parameter because it reflects the energy produced by the fuel. The study analyzed experimental data correlating the transesterification reaction time with the biodiesel calorific value. The results showed that the optimal reaction time was 80 minutes, yielding the highest calorific value of 41.35 MJ/kg, exceeding the ASTM D6751 standard. However, the effect of reaction time on calorific value was not statistically significant, with a P-value of 0.67 and a regression coefficient of 0.02. The decrease in calorific value after 80 minutes is likely caused by overreaction, reducing efficiency. The findings indicate that reaction time is not the sole factor influencing biodiesel calorific value. Future research recommendations include incorporating variables such as reaction temperature and raw material molar ratio to enhance model accuracy. This study is expected to provide a foundation for developing high-quality biodiesel that meets international standards.

Abstract

This Community Service activity addresses sheep manure waste issues at Umroh Farm, Patumbak Village, Deli Serdang. Waste buildup causes odor and environmental pollution despite its potential as biogas material. The solution was implementing appropriate technology by constructing a household-scale biogas reactor. Activities included participatory training, equipment assembly, and field trials. The digester, with a ±200-liter capacity, was made from plastic drums and equipped with input-output, cleaning, and gas collection lines. The implementation produced an average of 0.015 m³ of biogas per hour, with fire ignition lasting 1–2 seconds. The program reduced livestock waste, improved farmers’ awareness and skills and supported clean energy and climate change mitigation goals. Its success shows that simple biogas technology can provide an integrated solution for environmental management and community empowerment.

Abstract

  This study analyzes the effect of steam pressure variations from a small boiler on the mechanical performance of a Robinson Engine at a maximum pressure of 2.5 bar. A quantitative experimental method was applied with four pressure variations (1.0, 1.5, 2.0, and 2.5 bar). Performance parameters measured included rotational speed, torque, and power, with LPG fuel and water volume maintained as control variables. Results show a significant positive relationship between steam pressure and engine speed; increasing pressure from 1.0 to 2.5 bar raised the speed from 526.2 to 975.6 rpm. These findings highlight the dominant role of steam pressure in engine performance and provide initial quantitative data for developing micro-scale renewable energy-based power plants.
