Abstract

Fiber optic sensors offer a high-performance alternative because they provide a low-cost solution, resistance to electromagnetic interference, multiplexing capabilities, and high integration. The performance of fiber optic sensors applies to measuring physical parameters such as pressure, bending, and temperature. This study aims to determine the optimal value of using optical fiber types in landslide early detection sensors. The method used is bending in the form of deflection on the optical fiber. The deflection values used are 0 mm - 15 mm, 0 mm - 20 mm, and 0 mm - 25 mm. The optical fiber is placed horizontally in the middle of the bending tool. This bending affects the deflection of the optical fiber, resulting in the attenuation of light in the optical fiber. The deflection phenomenon results in light attenuation in the optical fiber. The sensitivity level of a single-mode fiber optic sensor is higher than a multimode. It shows the greater linearity value in each deflection treatment. Single-mode optical fiber linearity data on deflection variations of 0 - 15 mm, 0 - 20 mm, and 0 - 25 mm, respectively, are 0.9833, 0.9871, and 0.9847. At the same time, the linearity data of multimode optical fiber is 0.8926, 0.9841, and 0.9687. Single-mode optical fiber is more sensitive than multimode optical fiber. It is caused by the core diameter of single-mode optical fiber, which is much smaller than that of multimode optical fiber. The difference in core diameter results in differences in light propagation in the optical fiber. The small diameter of the core has a low dispersion level so that more light intensity is reflected into the core. Light attenuation occurs in a single-mode optical fiber due to macro bending treatment. Meanwhile, the attenuation of light in Multimode fiber optics is due to the bending and dispersion of light. Therefore, a landslide early detection sensor design is more optimal by using a single-mode optical fiber.

Abstract

The increasing use of motorcycles necessitates the development of more efficient and environmentally friendly fuel alternatives. This study examines the effect of mixing methanol with pertalite fuel on engine performance and exhaust emissions in carburetor motorcycles. The fuel variations tested include M0, M5, M10, M15, M20, and M25. Performance testing was conducted using a dynotest, while exhaust emissions were measured with an emission gas analyzer. The results indicate that M25 produces the highest torque and power output, particularly in the 2500–8500 rpm range. Additionally, M25 significantly reduces HC and CO emissions, with HC at 108.33 ppm vol and CO at 0.19% vol, compared to M0. The findings suggest that methanol-enhanced fuel improves combustion efficiency, enhances engine performance, and lowers emissions. Thus, methanol-pertalite blends offer a promising alternative for improving carburetor motorcycle performance while reducing environmental impact.

Abstract

Atomic Force Microscopy (AFM) is widely used for high-resolution topographic imaging, but sample preparation remains a critical factor influencing image quality. Wet preparation techniques improve nanoparticle dispersion but often introduce residual solvent layers that degrade imaging performance. This study investigates a modified microwave-assisted drying system designed to enhance AFM sample preparation. A commercial microwave was adapted with precise power, temperature, and time controls to optimize drying conditions and minimize aggregation. Various sample preparation methods, including dry preparation, conventional wet preparation, and microwave-assisted drying, were evaluated. AFM characterization showed that the modified microwave system produced samples with more uniform morphology, reduced particle aggregation, and improved topographic resolution. Contact angle measurements indicated enhanced solvent removal, leading to increased hydrophobicity and better substrate interaction. These results demonstrate that controlled microwave-assisted drying is an effective strategy for improving AFM imaging quality, offering a practical alternative to conventional drying methods.

Abstract

The increasing demand for efficient and precise manufacturing processes in the automotive industry has led to the development of automated assembly systems, including pneumatic-based tools. This study focuses on the design, development, and evaluation of a pneumatic Bush installation tool for motorcycle engine mounting production efficiency. The tool was tested against manual methods (hammer and jack) to compare installation time, accuracy, and defect rates (NG). A quasi-experimental approach was used, involving trial and error testing, prototype validation, and comparative analysis. The results showed that the pneumatic system significantly outperformed the manual method, with an 80% improvement in efficiency—reducing installation time from 120 seconds (manual) to 45 seconds (pneumatic). Additionally, Bush misalignment was reduced from 40% (manual) to 10% (pneumatic), while installation-induced defects dropped from 35% to only 5%. The findings demonstrate that the pneumatic-assisted tool provides more consistent pressure control, improved accuracy, and reduced error rates, making it a superior alternative to manual methods. This study contributes to the advancement of automated assembly technologies in the motorcycle manufacturing industry.

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

Heat treatment can alter the stiffness-related and energy-dissipation behaviour of structural steels, but its influence on the modal response of SS400 steel is still rarely reported using direct experimental modal testing. This study evaluates the effect of annealing temperature on the dynamic characteristics of SS400 steel specimens under free-free boundary conditions. Four specimen conditions were investigated: raw material and annealed specimens at 700 °C, 800 °C, and 900 °C. Each specimen had dimensions of 200 mm x 20 mm x 5 mm. Experimental modal analysis was conducted using an impact hammer with a fixed uniaxial accelerometer, six roving-hammer measurement points, 10 kHz sampling rate, H1 frequency response function, Hanning windowing, and PolyLSCF stabilization. The first two bending modes were identified. The first natural frequency decreased from 491.655 Hz in the raw material to 434.364 Hz after annealing at 900 °C, corresponding to an 11.65% reduction. The second natural frequency decreased from 1327.165 Hz to 1173.168 Hz, corresponding to an 11.60% reduction. Damping ratios also decreased with increasing annealing temperature, with the largest reduction observed at 900 °C. The results indicate that annealing temperature strongly affects the modal properties of SS400 steel, particularly by reducing frequency- and damping-related indicators at higher temperatures. The contribution of this work is the direct comparison of raw and annealed SS400 modal parameters using the same free-free impact-testing configuration, which provides a baseline modal-response dataset for vibration-sensitive SS400 applications.
