Abstract

Developing substitution products for mining equipment parts in local industries will have a significant economic impact. In addition, it will create independence in the supply of mining components, not relying on imports. However, Ceper metal casting area is still using traditional methods. This community service aims to improve product design and skills to support the supply chain availability of consumable mining equipment parts. Designing from existing components is not easy for small industries; therefore, it needs assistance from university experts. The method used design assistance in the production of bucket-adapter consumable parts. The mechanical engineering study program team assists with three stages of the process: (1) scanning, (2) triangulation, and (3) CAD modeling. The results showed that consumable parts had been successfully submitted to an industry partner to proceed to the following stages: (4) CAM and (5) machining. The consumable parts design improves quality and independence in manufacturing mining equipment parts. The local industry appreciated this activity because a good design can improve the process of developing consumable mining equipment parts.

Abstract

Continuing Professional Development (CPD) for teachers includes self-development activities, scientific publications, and innovative works. Scientific publications are often an obstacle to a teacher's career. Therefore, the skill of writing a scientific paper is a competency that must be possessed by teachers. This community service aims to provide assistance and improve scientific writing skills for Vocational High School (SMK) teachers. The method used consists of a classical approach of holding workshops and individual post-workshop assistance until submitting participant articles to scientific journals. Based on the results of the program, it was found that: (1) the teachers showed high enthusiasm in participating in the program; (2) there is one participant who successfully published his article in the Indonesian Sinta indexed journals; (3) participants who are still in the process and who have already had draft articles still need individual assistance until they can publish into scientific journals. The mentoring program is still needed on an ongoing basis so that writing culture is formed as a part of the CPD program.

Abstract

Wind turbines are typically classified as Horizontal Axis Wind Turbines (HAWT) or Vertical Axis Wind Turbines (VAWT). VAWT has a superior ability to accelerate from rest to rotation than HAWT, allowing it to rotate the rotor even when the wind speed is low; additionally, the produced torque is relatively high. Using the Savonius helix VAWT is one of the numerous methods for enhancing VAWT performance. The effect of the number of blades and the blade twist of the rotor or the angle of rotation of the blades on the rotor from the bottom end to the top end on the speed cut generated by the VAWT Savonius helix was investigated experimentally. Variations in the number of blades used in the study included 2 and 3 blades, as well as 90°, 180°, 270°, and 360° for the rotor twist blades. In a wind tunnel, data was collected at wind speeds ranging from 0 to 5 m/s. The best performance research results were obtained With three blades, a twist angle of 180 degrees, and a cutting speed of 1.51 m/s. By modifying the Savonius Helix VAWT design in this study, it is possible to increase the efficiency and performance of turbines, mainly when used at low wind speeds, and the potential for using wind energy as a more efficient and sustainable alternative energy source.

Abstract

The availability of fossil resources is decreasing, cause government and private sectors to race in developing renewable energy. One solution is to create Wind Power Plants to meet energy demands. The Savonius turbine, also known VAWT, this great potential to meet small-scale energy needs. Savonius turbines have lower performance compared to other types. This performance needs to be enhanced through design modifications, such as varying the number of blades. This research purpose is to analyze effect number of blades on performance of helical Savonius turbines. This research focuses on airflow patterns with varying blade numbers in helical Savonius turbines. These turbines numerically studied using Computational Fluid Dynamics (CFD) approach with ANSYS Fluent. Each variation of blade numbers will simulate at wind speeds between 1 to 5 m/s. Numerical testing results will provide visualizations in form contour and vector within pressure or velocity scope for each variation. Based on visualization of numerical testing results, found that number of blades affects flow patterns. Increasing the number of blades increases turbulence flow. Pressure on convex surface also increases with the addition of blades. These two airflow phenomena reduce turbine performance, so two blades produce most optimal performance due to minimal resistance they experience.

Abstract

The increasing number of motorcycles in Indonesia, exceeding 125 million units in 2022, reflects the high demand for efficient and environmentally friendly vehicles. This trend drives the advancement of combustion system technology, notably the shift from carburetors to Electronic Fuel Injection (EFI). EFI is an electronically controlled fuel delivery system designed to optimize combustion through precise control of ignition timing and fuel injection duration. This system has proven effective in improving engine efficiency and reducing exhaust emissions. However, most mass-produced motorcycles are still equipped with non-programmable ECUs, limiting tuning flexibility. This study evaluates the use of an Arduino-based programmable ECU as a more adaptive alternative. Experiments were conducted on a Honda Vario 110cc FI, varying ignition timing (+2°, +4°, +6°, +8°, +10° BTDC) and fuel injection duration (+5%, +10%, +15%) using Pertamax RON 92 fuel. The results showed an 8% increase in maximum torque (16.98 N.m) at +4° and +5% configuration, and a 3% increase in maximum power at +2° and +10%. The lowest HC and CO emissions were recorded at +2° and +5%, with reductions of 44% and 41%, respectively. The Arduino-based ECU effectively enhances engine performance while maintaining emission efficiency.

Abstract

This study aims to investigate the effect of nozzle temperature variations on the tensile strength and surface hardness of 3D-printed specimens using polypropylene (PP) filament derived from instant noodle packaging waste. The filament was produced through an extrusion process at 200°C and subsequently printed into test specimens using Fused Deposition Modeling (FDM) with nozzle temperatures of 190°C, 200°C, and 210°C. Tensile testing was conducted in accordance with ASTM D638 Type IV, while hardness testing was performed using the Shore D method. The results show that nozzle temperature significantly affects the mechanical and physical properties of the specimens. The optimum performance was obtained at 200°C, yielding a tensile strength of 16.83 MPa and a hardness of 47.80 Shore D. At 190°C, both tensile strength and hardness decreased, while at 210°C hardness increased but tensile strength declined due to potential thermal degradation. Therefore, 200°C is identified as the optimum temperature, providing the best balance between mechanical performance and structural stability
