Abstract

The performance of vortex turbines in ultra-low-head hydropower plants is crucial for harnessing energy in irrigation channels and small rivers. Therefore, an optimal design is needed to maximize the conversion of flow energy into electrical power. This study aims to evaluate and determine the best-performing configuration of ultra-low-head vortex turbines. The method used is Computational Fluid Dynamics (CFD) simulations employing the k-ω Standard turbulence model, with variations in the number of blades (3, 5, and 7) and a fixed blade angle of 15°. The results show that the 7-blade configuration with a 15° angle provides superior performance, generating 3.90 W of power, reducing NPSH by 2%, and increasing force by 6%, with a force value of 52.65 N. The implications of these findings suggest that the 7-blade–15° configuration is a suitable design reference for optimizing ultra-low-head vortex turbines in micro-scale hydroelectric power plants, supporting the utilization of renewable energy in irrigation networks and rural areas.

Abstract

This article aims to examine the life lessons of The Doctor Valentino Rossi, in order to create a spirit of life-giving impressions of Islamic education, by analyzing them to provide a better understanding of the theme and to suggest emerging directions for future research. The writing is character research, with a descriptive qualitative setting. The results of the research show that Valentino Rossi's life journey in achieving various achievements cannot be separated from a strong life mindset by compromising between the realities of life and spiritual practice. This fact in the domain of Islamic education is a form of integrating knowledge organically, comprehensively and holistically. This can be used as an impression for Islamic education. Research implications: the need for improvised research to narrow the dichotomy of science and life reality. The study suggests multidisciplinary research as a starting point for the development of Islamic education.

Abstract

The waste discarded by the community every day comes from agricultural activities, markets, households, entertainment, and industry. One form of waste is domestic waste, which originates from household waste. The increase in domestic waste goes hand in hand with the development of physical infrastructure and the expansion of adequate facilities and infrastructure. As a result of this pollution, environmental balance is disrupted. In this experiment, one method will be used to reduce or minimize environmental pollution, especially air pollution, by using an electrostatic precipitator as a tool to capture solid particles from exhaust gas in waste combustion smoke. It is expected to efficiently reduce the solid particle content in the exhaust gas from waste combustion. The electrostatic precipitator is an alternative for reducing environmental pollution, as it has high efficiency, reaching 98.4%, and can capture particles as small as 100 micrometers. The electrostatic precipitator works by capturing solid particles that pass through the particle charging area, which is at a high potential. The charging area provides high-speed electrons by ionizing molecules and particles in the exhaust gas from the smoke. The exhaust gas particles receive positive ions and become highly charged, allowing them to be attracted and captured by negatively charged electrodes (collecting plate). Through this process, the solid particle content in the exhaust gas from waste combustion can be eliminated. Therefore, this final project involves the development of an electrostatic precipitator prototype aimed at reducing environmental pollution, particularly air pollution.

Abstract

Global plastic production exceeds 390 million tons annually, yet only about 9% is recycled, leaving severe environmental impacts. Pyrolysis is emerging as a promising solution, converting plastic waste into fuels and chemicals. However, popular claims on mass media and commercial technology publications, that 1 kg of plastic yields 1 liter of fuel are misleading, as they ignore differences in mass, volume, and fuel density. Pyrolysis oil can indeed serve as fuel but often needs further refining to meet engine standards. Economically, it holds potential, with oil prices ranging from USD 600–900 per ton and syngas generating up to 800 kWh per ton. Nonetheless, high capital and operational costs challenge its feasibility, particularly for small-scale operations. Environmentally, pyrolysis aligns with sustainability and circular economy goals, potentially reducing emissions by up to 3.5 tons of CO₂-equivalent per ton of plastic processed. This paper examines pyrolysis critically, addressing misconceptions and evaluating its realistic prospects as both an environmental solution and a business venture.

Abstract

The global energy crisis and continued reliance on fossil fuels have intensified the search for sustainable alternative energy sources, particularly biomass-derived biofuels. One promising yet underutilized resource is the peel waste of Carica pubescens, a papaya variety indigenous to the Dieng Plateau. This study investigates the potential of Carica peel waste as a bioethanol feedstock through sulfuric acid (H₂SO₄) hydrolysis and fermentation using Saccharomyces cerevisiae. To optimize sugar yield, the concentration of H₂SO₄ was varied between 0.1 M and 0.8 M, while fermentation durations were set at 96, 120, 144, and 168 hours. Results indicated that hydrolysis with 0.8 M H₂SO₄ produced the highest sugar concentration (6.8%). The most effective fermentation period was 120 hours, yielding 64% bioethanol with a density of 0.8679 g/mL, a calorific value of 4,831 kcal/kg, a flame height of 14.6 cm, and a combustion temperature of 438°C. These findings demonstrate the viability of Carica peel waste as a valuable raw material for bioethanol production. Its high efficiency and favorable fuel properties highlight its potential for integration into local renewable energy initiatives, contributing to sustainable energy development. Further studies on large-scale implementation and process optimization are recommended to maximize its industrial application.

Abstract

The increasing demand for energy and the environmental impacts of fossil fuel consumption have encouraged the development of renewable and sustainable energy sources. Bioethanol derived from lignocellulosic biomass represents a promising alternative fuel due to its renewability and reduced competition with food resources. This study investigates the potential of tobacco stalks, an underutilized agricultural residue, as a feedstock for bioethanol production through acid hydrolysis and fermentation processes. Dried tobacco stalks were hydrolyzed using 1 M sulfuric acid at 110 °C for 3 h to produce fermentable sugars, followed by batch fermentation using Saccharomyces cerevisiae with variations in yeast concentration and fermentation time. The fermentation products were purified by simple distillation and characterized using refractometry, density measurement, GC–MS, and bomb calorimetry. The hydrolysis process yielded a sugar concentration of 7.6%. Refractometric analysis indicated ethanol concentrations in the range of 64–68% (v/v), while density measurements suggested lower effective ethanol purity due to residual water and non-ethanol components. GC–MS analysis confirmed ethanol as the dominant compound, with relative contents ranging from approximately 52% to 73%, accompanied by acetic acid and minor volatile by-products. The calorific value of the produced bioethanol ranged from 4,825 to 4,983 kcal/kg and increased with fermentation time. The results demonstrate that tobacco stalks have considerable potential as a lignocellulosic feedstock for bioethanol production, although further process optimization is required to enhance ethanol purity and overall conversion efficiency.

Abstract

This study analyzes the performance of the diesel engine in terms of power, torque, specific fuel consumption, and thermal efficiency using diesel and pyrolysis oil. The waste plastic oil (WPO) used in this research was produced through a pyrolysis process using raw materials from Low-density Polyethylene (LDPE) mixed with diesel fuel in volume ratios WPO10, WPO20, WPO30, WPO40, and WPO50. In addition, a performance test was carried out on the single-cylinder diesel engine test bench. The results showed that performing the diesel engine with the addition of WPO increased the average power and torque by 5% and 3%, thereby producing a higher heating value. Furthermore, the concentration of WPO also reduces the level of specific fuel consumption to be more efficient, with a decrease in thermal efficiency. In conclusion, plastic waste pyrolysis oil is a promising alternative fuel applicable to a diesel engine.
