Abstract

Purpose: To determine the regulation of the rotation speed of a DC motor using an NE 555 type IC and by providing a stable voltage with the same working frequency but varying DC motor speed control pulse cycles. Methodology: This research method includes several stages, the stages in the research are as follows: The data required is the specifications of each component and the specifications of the hardware design to be made. The selection of tools and materials used must be in accordance with what is expected for setting and controlling the speed of a DC motor Result: The effect of the armature current (Ia) on the rotation speed of the motor is directly proportional; that is, the greater the rotation speed of the series self-amplifying DC motor. Conclusion: DC motor speed increases with Va and Ia. IC NE555 enables simple, affordable PWM control, though manual potentiometer adjustment lacks precision. Limitations: Dependence on specific ICs: Focusing on the use of the NE 555 IC may limit the understanding of other alternatives that may be more suitable or efficient for certain applications. This article could be better if it includes a comparison with other available methods or ICs. Contribution: This study can provide practical insight into how to implement DC motor speed adjustment in various applications, such as in the fields of automation, robotics, and other small control systems. This may help readers who wish to apply the techniques taught in their projects.

Abstract

Purpose: This study aims to determine what variables affect during hydrolysis, and the results of this hydrolysis process will be tested for raw materials in making Bioethanol Research methodology: The research was carried out for 3 months, namely April – June 2023, which was carried out at the Laboratory of the Chemical Engineering Department of the Sriwijaya State Polytechnic, Palembang. Results: The ethanol content obtained from the hydrolysis of cempedak seeds is 28.37%.. Conclusion: The highest brix value of 8.7% was obtained at 100 minutes of hydrolysis with 3% HCl concentration. GC-MS results showed an ethanol content of 28.37% with a refractive index of 1.335. Limitations: One of the main limitations of this study might be related to the laboratory-scale nature of the research. Many studies are conducted on a small scale and have not been applied to industrial-scale production. This can be a constraint because a hydrolysis process that works at a small scale may not be easily translatable to mass production. Contribution: This article contributes to the utilization of agricultural waste, specifically cempedak seeds, which are often discarded or underutilized. This has the potential to reduce waste and add value to a product previously considered useless.

Abstract

This study aims to synthesize and characterize ultrafiltration membranes based on polyethersulfone (PES) with the incorporation of titanium dioxide (TiO?) as an organic catalyst at varying concentrations (0%, 1%, and 2%). The goal is to evaluate the impact of TiO? addition on the structural and morphological properties of PES membranes to improve water treatment performance. Research/methodology: Membranes were fabricated using the phase inversion technique, employing N,N-dimethylacetamide (DMAc) as the solvent and polyvinylpyrrolidone (PVP) as the pore-forming additive. Characterization techniques included Fourier-transform infrared spectroscopy (FTIR) for functional group identification, scanning electron microscopy (SEM) and atomic force microscopy (AFM) for morphological analysis, contact angle measurement for hydrophilicity, porosity testing, and pure water flux evaluation. Results: The addition of TiO? improved the hydrophilicity of PES membranes, reducing the contact angle from 68.2° to 53.7°, and increased porosity from 48.78% to 67.75%. Morphological analysis showed enhanced pore distribution and surface structure. The membrane with 2% TiO? achieved the highest water flux of 5.77 L/m²·h. Although this value is below the typical ultrafiltration standard (10–50 L/m²·h), the improvements indicate the potential of TiO? to enhance membrane performance. Conclusions: Incorporating TiO? into PES membranes significantly enhanced their hydrophilicity, porosity, and structural uniformity. The optimal performance was observed at a 2% TiO? concentration. Limitations: The study is limited by the non-uniform dispersion of TiO? particles and was conducted under laboratory-scale conditions without real-world application testing. Contribution: This research provides insight into the role of TiO? in improving PES membrane characteristics and serves as a practical reference for developing advanced ultrafiltration membranes for water treatment applications.

Research/methodology: Membranes were prepared via phase inversion using N, N-dimethylacetamide (DMAc) as the solvent and polyvinylpyrrolidone (PVP) as an additive. The characterization techniques used included FTIR (functional groups), SEM and AFM (morphology), contact angle measurements (hydrophilicity), porosity testing, and pure water flux analysis. Results: TiO ? addition significantly improved the membrane properties. Hydrophilicity increased as the contact angle decreased from 68.2° to 53.7. The porosity increased from 48.78% to 67.75%, and the 2% TiO? membrane exhibited the best surface structure and pore distribution. It also achieved the highest water flux at 5.77 L/m²·h, although still below the typical ultrafiltration standard (10–50 L/m²·h). Conclusions: Incorporating TiO? enhanced the hydrophilicity, porosity, and uniformity of PES membranes. The 2% TiO? membrane demonstrated optimal performance despite not achieving the standard ultrafiltration flux. Limitations: The limitations of this study include the non-uniform dispersion of TiO? particles and the testing conducted only under laboratory conditions, which may not accurately reflect real-world performance. Contribution: This study demonstrates the potential of TiO ? in improving PES membrane performance for water treatment and provides a practical reference for developing advanced ultrafiltration membranes for industrial applications.

Abstract

Purpose: This study aimed to evaluate the effectiveness of activated charcoal from rice husks and Kepok banana peels in improving Sekanak River water quality, focusing on pH stabilization and iron (Fe) removal. Methodology: Activated charcoal was produced via carbonization, followed by sieving and characterization based on the moisture content, ash content, and volatile matter. Adsorption tests were conducted using varying adsorbent masses (35–55 g), and the water quality parameters (pH and Fe) were measured before and after treatment. Results: Both adsorbents met the SNI 06–3730–1995 standards: moisture content <15%, ash <10%, and volatile matter <25%. Using 55 g of banana peel charcoal reduced the Fe content from 0.40 mg/L to 0.049 mg/L and increased the pH from 6.59 to 7.27. Rice husk charcoal increased the pH to 7.16. Banana peel charcoal exhibited slightly better performance in both iron removal and pH improvement. Conclusion: Activated charcoal from banana peels and rice husks effectively improved water quality. Both met national standards, with banana peel charcoal offering slightly superior performance in reducing Fe and stabilizing pH. Limitation: This study was limited to laboratory-scale experiments on a single water source, without long-term or real-field testing. Only one activation method was used. Contribution: This study supports the use of low-cost, eco-friendly materials such as rice husks and banana peels as effective adsorbents for water treatment, offering sustainable solutions particularly suited for rural or resource-limited areas.

Abstract

Purpose: This study aimed to evaluate the effectiveness of TiO? photocatalysis with varying UV light intensities in degrading color, reducing iron content, and improving pH in peat water, which is naturally acidic and rich in organics. Methodology: Peat water was treated using TiO? doses of 1.5 g and 2.5 g under 24 W and 32 W UV lamps for 3–6 h. The analyzed parameters included color (TCU), pH, iron (Fe), and E. coli counts. The experiments used a batch reactor with multiple UV sources to enhance the photocatalytic activity. Results: Color was completely removed (100%) under all treatment conditions. The highest Fe reduction (97.8%) occurred using 1.5 g TiO? under 24 W UV irradiation for 4 h. The highest pH increase (62.33%) was achieved using 2.5 g TiO? under 32 W UV for 6 h, raising the pH from 3.00 to 4.87. E. coli was fully eliminated in all variations. Conclusion: TiO? photocatalysis effectively removed color, iron, and bacteria from peat water. However, although the pH improved, it remained below potable water standards, indicating the need for further treatment. Limitation: The study was limited to laboratory-scale conditions and did not achieve neutral pH levels, requiring additional post-treatment and field validation for practical application. Contribution: This study highlights TiO?/UV photocatalysis as a promising method for advanced peat water treatment. This study offers insights into optimizing treatment parameters for improved water quality in future applications.

Abstract

Purpose: This study investigated the effectiveness of combining the Fenton process with TiO? photocatalysis to improve peat water quality by reducing TSS, BOD, Fe, color, and bacterial contamination. Methodology: Peat water samples were treated in a batch reactor using TiO? doses of 1.5 g and 2.5 g under UV exposure for 2, 4, and 6 h. Hydrogen peroxide (H?O?) and TiO? served as oxidants and photocatalysts, respectively. The parameters measured before and after treatment included TSS, BOD, Fe, pH, color, and E. coli. Results: The best performance was achieved with 2.5 g TiO? and 4 h of UV exposure, reducing BOD to 1.65 mg/L, TSS to 17.8 mg/L, Fe to 0.36 mg/L, and fully eliminating E. coli. However, the pH remained acidic at 2.93. The process was effective in removing pollutants and disinfecting water, although it was insufficient for pH neutralization. Conclusion: The combined Fenton–TiO? process significantly enhanced peat water treatment by reducing major pollutants and bacterial contamination. Optimal results were achieved with 2.5 g TiO? and 4-hour UV exposure, but further treatment is required to raise the pH to potable standards. Limitations: The process failed to achieve neutral pH levels and was tested only in a laboratory-scale setting, without evaluating real-world scalability. Contribution: This study supports the use of Fenton–TiO? photocatalysis as a promising method for treating heavily polluted peat water. This study provides operational insights for the development of advanced oxidation-based systems for sustainable water purification.
