<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>
