Abstract

Constructing a small-scale hydroelectric power station that can run efficiently at a head lower than 10 m is one possible method for reducing the impact of the electricity crisis in remote areas of Indonesia. The Archimedes Screw turbine is one type of turbine that is ideal for discharges below 10 m. In this study, the simulation results show that the value of Turbulences Kinetic Energy is directly proportional to the increase in flow rate but inversely proportional to the level of immersion. This type of turbine is unless well in Indonesia due to a lack of information regarding the application of low head power plants. The turbine model that is suitable for the low head is investigated in this study. Before being tested, the turbine is first designed theoretically and then numerically evaluated. With discharges of 1 l/s, 2 l/s, and 3 l/s and turbine immersion levels of 30%, 50%, and 70%, ANSYS CFD (Computational Fluid Dynamic) software was used to investigate flow rate and level of immersion in the turbine. According to the investigation findings, the discharge has a considerable impact on the turbine's movement; the higher the flow rate, the higher the power to the turbine, which produces a torque on the turbine. The simulation findings indicate that the value of Turbulence Kinetic Energy is proportional to the increase in flow rate but inversely proportional to the level of immersion.

Abstract

Purun tikus (Elocharis dulcis), a type of wetland biomass feedstock, is a challenge to the swamp ecosystem as it contributes to pollution in the area. Hence, integrating the use of purun tikus as a source of bioenergy, particularly in the form of bio-oil, is of the highest priority. Nevertheless, there is a lack of research on the degradation rate of purun tikus conversion to bio-oil through pyrolysis. Thus, this study aims to evaluate the rate of destruction of purun tikus in the process of conversion into bio-oil via pyrolysis. In the experiment, a batch reaction vessel was used to carry out slow pyrolysis at temperatures ranging from 300 to 500 °C, and the reaction times ranged from 60 to 120 min. By assuming a first-order process and using the Arrhenius equation, it was possible to figure out the activation energy and the preexponential factort. To determine whether purun tikus destroyed during pyrolysis, an activation energy of 43.317 kJ mol-1 and a pre-exponential factor of 0.351 s-1 were identified.

Abstract

This study explores the optimization of bio-oil additives derived from the pyrolysis of Ulva lactuca algae, blended with RON 90 gasoline to enhance engine performance and reduce emissions. Addressing the urgent need for sustainable energy, the research focuses on a relatively unexplored area—using algae-derived bio-oils in gasoline engines. The study aimed to identify the optimal blend ratio of bio-oil and gasoline to improve engine metrics such as brake specific fuel consumption (BSFC), thermal efficiency, and volumetric efficiency, while minimizing emissions like CO, CO2, and NOx. Experiments were conducted with bio-oil blended at 5%, 10%, and 15% by volume with RON 90 gasoline in a single-cylinder gasoline engine. Results showed that increasing bio-oil concentration led to improved fuel efficiency and thermal efficiency, along with significant reductions in CO and HC emissions. However, NOx emissions presented a complex trend, increasing at lower bio-oil ratios but decreasing significantly at the highest concentration. These findings suggest that algae-derived bio-oil can effectively enhance gasoline engine performance and reduce environmental impact, offering a novel, sustainable alternative fuel option. The study underscores the importance of optimizing blend ratios to maximize benefits and manage emissions, contributing valuable insights to sustainable energy research.
