Abstract

The amount of methylene blue (MB) in water bodies is one of the environmental issues that still need to be considered. The vast concentration of MB may increase the chemical oxygen demand level, so it has the potential to disrupt aquatic ecosystems. On the other hand, the adsorption process is one of the best methods that functionalizes as a utility for dye removal. This research studied the MB adsorption characteristic using cellulose-based adsorbent from banana fronds. Adsorbents were synthesized and modified using chitosan, bentonite, and acid addition. The adsorption process occurred at various concentrations of MB (40, 60, 80, 100, and 120 ppm) then the result will be proved and calculated by analysis using UV Vis and FTIR Spectrophotometer. The result showed that the bentonite addition could not increase the adsorption capacity optimally due to fluctuating spectrum of UV-Vis. In conclusion, the adsorbent can absorb MB in wastewater which is the optimal condition at 80 ppm for 24 hours.

Abstract

This research aims to 1) to determine operating conditions that correspond to the amount of fuel needed to be distributed, 2) visualize the profile of pressure changes with pipe distance, and 3) compare actual conditions with simulated conditions. The research method consists of simulation of energy loss in the form of pressure drop for each type of fuel oil (gasoline and gasoil) using ASPEN Plus® software. Research results show that a greater pump pressure of 87 bar is required to distribute gasoil, compared to gasoline which only uses 82 bar to reach ideal atmospheric pressure at 750 m3/hour. Reduction in fuel pumping pressure is close to linearity, where pumping pressure will continue to decrease as piping distribution distance increases. % error is obtained by comparing the simulation results with the industrial standard which is evidenced by % error of 7.69 (moderate) in the type of gasoline fuel and % error value of 1.81 (strong) in the type of gasoil fuel. This research has been in accordance with the real conditions in the field, so it can predict the right conditions to maximize the process.

Abstract

Global electricity demand continues to rise, increasing dependence on fossil fuels and accelerating greenhouse gas emissions that contribute to climate instability. Small-scale hydropower offers a clean alternative, particularly for distributed and space-constrained applications where conventional hydropower systems are difficult to implement. Among available concepts, the Savonius Pico-Hydro Turbine (SPHT) is attractive because of its simple structure, low production cost, and good self-starting capability. However, previous studies have mainly focused on mechanical performance, while the combined evaluation of mechanical response, electrical output, generator efficiency, and hydrodynamic flow behavior remains limited. The novelty of this study lies in the use of a quarter-circular blade profile instead of the commonly used semi-circular Savonius blade, combined with experimental electromechanical testing, CFD-based flow visualization, and deflector-angle variation. Two- and four-blade SPHT configurations were examined under realistic loading conditions, while CFD simulation was employed to clarify velocity distribution, pressure loading, momentum exchange, and deflector-guided flow patterns. The results showed that the four-blade rotor produced higher torque and a stronger electrical response than the two-blade rotor. CFD contour analysis supported these findings by showing stronger momentum exchange and more distributed pressure loading around the higher-solidity rotor. The deflector investigation further indicated that a 30° deflector angle provided the most effective flow redirection and pressure distribution among the evaluated cases. Overall, the proposed experimental and numerical framework provides a practical basis for optimizing quarter-circular SPHT design through blade configuration selection and deflector-angle tuning, supporting compact and reliable pico-scale clean energy generation for remote and low-infrastructure applications.
