Abstract

The research aims to design and develop an electric wheelchair based on the Arduino Uno microcontroller as a mobility solution for individuals with disabilities. A conventional wheelchair was modified by integrating an electric drive system controlled by an analog joystick, which is connected to the Arduino Uno and DC motors via a BTS 760 motor driver. The wheelchair design complies with ISO 7176-5 standards and is adapted to the anthropometric dimensions of Indonesian users. Test results indicate that the control system functions effectively, allowing responsive control of wheelchair movements forward, backward, left, and right according to joystick operation. However, several challenges were encountered during the chain adjustment and gear welding processes, requiring further development to achieve optimal performance. This study demonstrates that utilizing the Arduino Uno as the central control unit enables the production of an electric wheelchair at a more affordable cost.

Abstract

Catheter-associated urinary tract infections (CAUTIs) are among the most frequent healthcare-associated infections, primarily caused by biofilm formation on catheter surfaces. This narrative review summarizes recent progress in antimicrobial urinary catheter development, focusing on substrate materials, functional agents, and fabrication strategies. Common substrates such as silicone, polyurethane, and thermoplastic elastomers provide biocompatibility and durability but require modification to achieve antimicrobial performance. Strategies including surface coatings (e.g., dip- and spray-coating, sol–gel, and layer-by-layer deposition), impregnation, composite blending, and hybrid designs have been investigated to deliver sustained antimicrobial release, antifouling resistance, and improved patient comfort. Coating-based methods enable localized control of active agents, while bulk modifications ensure durability despite surface wear. Emerging approaches highlight multifunctional systems that integrate antimicrobial, antifouling, and lubricious properties, supported by precision techniques such as nanostructured coatings and bioinspired surface engineering. By linking material selection with fabrication design, this review underscores the need for scalable and cost-effective strategies that combine long-term antimicrobial protection, mechanical integrity, and regulatory compliance. Future research directions include hybrid fabrication methods, sustainable manufacturing, and clinical translation to reduce the global burden of CAUTIs.

Abstract

Additive Manufacturing (AM) or 3D printing using the Fused Deposition Modelling (FDM) method offers high flexibility in the production of polymer components through process parameter settings, one of which is the infill percentage that affects mechanical performance. This study analyzes the effect of infill variations (25%, 50%, 75%, 100%) on the mechanical properties of two popular thermoplastic materials, Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS). Testing was conducted according to ASTM standards, including tensile strength, bending strength, impact strength, hardness, and density. The results show that PLA has higher tensile strength (47–53 MPa), bending strength, and hardness compared to ABS (33–38 MPa). Conversely, ABS demonstrates better toughness through higher impact values, while the difference in density is relatively small and insignificant. Increasing the infill percentage is proven to enhance strength and hardness in both materials, but this is accompanied by an increase in material consumption. These findings indicate a trade-off between stiffness and toughness, so material selection must be tailored to application requirements. PLA is more suitable for precision components requiring dimensional stability, while ABS is recommended for applications with dynamic loads and impact risks. This study provides a practical foundation for optimizing FDM parameters, particularly material and infill, in engineering, medical, and consumer product applications.

Abstract

Laboratory activities such as practical courses, research experiments, and sample analyses often generate waste, with liquid effluents being the most prevalent. Proper treatment of these liquid wastes is essential prior to discharge into the environment to prevent contamination. Photocatalysis, a process that employs photon-activated semiconductor oxides, has emerged as a promising approach for wastewater treatment. In this study, bismuth oxide was developed as an alternative photocatalyst capable of operating under both UV and visible light. The material was synthesized via the sol–gel method and subsequently deposited using a spray-coating technique. The fabricated photocatalytic reactor was designed with integrated reaction chambers, control systems, and adjustable light intensity to enhance wastewater purification. Reactor parameters were systematically optimized to establish the most effective configuration for pollutant degradation. Experimental results demonstrated that higher light intensities significantly reduced the absorbance of liquid effluents, indicating a substantial decrease in contaminant concentration. Furthermore, the chemical oxygen demand (COD) and biological oxygen demand (BOD) of treated wastewater decreased by 24% and 64%, respectively.

Abstract

The increasing demand for energy efficiency and lightweight transportation has encouraged the development of three-wheeled vehicles with optimized structural frames. This study evaluates the static and dynamic performance of three-wheeled vehicle frames using three high-performance materials Aluminium 7075-T6, S690 steel, and ASTM A572 HSLA 60 steel. Finite Element Analysis (FEA) was conducted with Altair HyperWorks to analyze stress distribution, deformation, safety factor, and natural frequency response. Static analysis results indicate that all materials are structurally safe, with S690 steel showing the highest stiffness and safety factor, while Aluminium 7075-T6 provides the greatest strength-to-weight efficiency despite higher deformation. ASTM A572 HSLA 60 offers moderate performance as a cost-effective alternative. Modal analysis reveals similar natural frequency ranges (1.5–3.2 Hz) across all materials, indicating that dynamic behavior is more influenced by geometry than material properties. The findings highlight the trade-off between strength, stiffness, and weight, suggesting Aluminium 7075-T6 as the optimal choice for lightweight and energy-efficient applications, while S690 steel is preferable for heavy-duty requirements. Overall, this research emphasizes a holistic approach in material selection for three-wheeled vehicle frames to balance mechanical strength, vibration characteristics, and energy efficiency.
