Abstract

The depletion of fossil energy reserves, especially oil and natural gas, has driven innovations in energy-efficient vehicles, including through the Energy-Efficient Car Contest (KMHE). In developing prototype cars for this competition, driver ergonomics is often overlooked. This study aims to analyze musculoskeletal complaints experienced by prototype car drivers from the Faculty of Engineering at UNP. The main instrument used was the Nordic Body Map (NBM) questionnaire, administered to three drivers after they performed a 20-minute static driving simulation. The collected data were analyzed and categorized based on complaint levels. The results showed that the most frequent complaints occurred in the lower back (score 12), followed by the lower neck, buttocks, and hips (score 11). The average overall score was 71.67, indicating a high-risk category. The highest individual score was 89 (Driver 3), and the lowest was 62 (Driver 1). These complaints were caused by the absence of an ergonomic driver seat in the prototype car. The study concluded that the current cockpit design is not ergonomically adequate, posing a risk of injury. Therefore, it is recommended that the design team immediately create a more upright driver seat with thigh support to enhance comfort and reduce musculoskeletal complaints.

Abstract

The Vocational Pedagogy course is an important factor in supporting students' teaching readiness. Observation shows that PLK students have a gap in teaching readiness even though they have taken Vocational Pedagogy courses. This study describes the teaching readiness of students in the Mechanical Engineering Department at Padang State University and analyzes the effect of the course on teaching readiness. The study employed a causal quantitative approach, surveying 92 students from the 2020 and 2021 cohorts, selected via Proportionate Stratified Random Sampling. Data were collected via a questionnaire and analyzed using descriptive analysis and simple linear regression. The results showed that students' mastery of the Vocational Pedagogy course was high, with an average score of 4.5. Students' teaching readiness was also in the "ready" category, with an average score of 4.5. Hypothesis testing results show that vocational pedagogy courses positively and significantly impact student teaching readiness. The coefficient of determination (R-square) is 0.545, meaning 54.5% of teaching readiness variables are influenced by vocational pedagogy courses, while other factors influence the rest. This study concludes that Vocational Pedagogy courses significantly and positively impact teaching readiness among students in the Department of Mechanical Engineering at FT-UNP. Micro teaching is a crucial factor in improving teaching readiness in this course.

Abstract

The development of electric vehicles in Indonesia has grown rapidly, supported by the Indonesian Electric Car Competition (KMLI) which encourages innovation in designing lightweight yet strong vehicle frames. The tubular space frame of the “Megathrust Electric” car previously used ASTM A36 steel with a total weight of 32 kg, which was considered inefficient as it increased power consumption and reduced overall performance. This study aims to analyze the effect of pipe dimension variations and alternative materials, namely Aluminium alloy 6061 and 6063, on the strength and deformation of the frame. The method employed is Finite Element Analysis (FEA) using SolidWorks software under static loading conditions that represent real operating scenarios. The pipe variations examined include 19.05 mm diameter with 2.5 mm thickness and 25.4 mm diameter with 2 mm thickness. The simulation results show that the 25.4 × 2 mm Aluminium alloy 6061 configuration provides the best structural performance with a maximum stress of 55.07 MPa, deformation of 1.583 mm, and a safety factor (FOS) of 5.012. In contrast, the 19.05 × 2.5 mm Aluminium alloy 6063 configuration is lighter but exhibits higher stress (184.4 MPa) and a lower safety factor (1.161). Therefore, the Aluminium Alloy 6061 pipe with 25.4 mm diameter is recommended as the optimal frame design, offering a balance between strength, stiffness, and weight efficiency to support the performance of electric vehicles in competition.

Abstract

This training activity was conducted for a group of farmers in Saureinu Village, Mentawai Islands Regency. Based on the team's observation data, we found that many farmers in Saureinu Village still do not understand how to maintain agricultural machinery. As a result, many agricultural machines in Saureinu Village are damaged and cannot be used, thereby reducing farmer productivity. Through this activity, training on agricultural machinery maintenance was provided to the Saureinu village farmer group using the Practical Demonstration method. The Practical Demonstration method was considered appropriate for participants who had diverse backgrounds and no prior understanding of machinery. Based on the team's assessment at the beginning and end of the activity, there was an increase in the participants' knowledge and competence related to the material provided. In the theory session, participants' knowledge increased by 52%, and in the practice session, participants' competence increased by 40%. Participants' mastery of each sub-topic increased by 35-40%. Based on the conversion of scores to assessment categories, this activity was able to improve participants' competencies from poor to good. This improvement is expected to enable the Saureinu Village farmer group to maintain the agricultural machinery they use and maintain stable agricultural productivity.

Abstract

This paper presents a systematic literature review of published research on the use of areca nut bark fibres as a reinforcing material in polymer composites. A total of 22 research articles published in Scopus-indexed journals were identified and analysed in depth. In addition, this article presents current issues related to areca nut husk fibre (ANHF) as a reinforcement in composites using the VOSviewer tool. In this article, the authors explains the processing stages of ANHF before it is used as a reinforcement in composites. The chemical treatments carried out are also summarised in this article. Not all types of resins available on the market have been used as matrix in the manufacture of areca nut shell fibre composites. The use of additives derived from natural materials has also been found to be effective in improving the quality of ANHF composites. This article also highlights the need for further research to improve the quality of areca nut husk fibre composites and discusses the unanswered aspects of the published research.

Abstract

This study evaluates the static structural performance of a Prototype-class energy-efficient vehicle chassis for the Indonesian Kontes Mobil Hemat Energi (KMHE; Energy-Efficient Car Competition) by comparing two material options, AISI 1020 carbon steel and Al 6061-T6, under a consistent load representation. Three-dimensional chassis models were developed in SolidWorks and assessed using static finite element analysis (FEA). The loading scenario included gravitational body force and two concentrated static loads representing operational conditions: 700 N applied at the driver seat region and 300 N applied at the engine mounting area. A curvature-based meshing strategy was adopted, with element sizes ranging from 1.6 to 8 mm, resulting in approximately 1,700,093 nodes to capture geometric details in joints and curved members. The AISI 1020 chassis produced a maximum von Mises stress of 278.6 MPa concentrated near the engine mounting joint, a maximum total deformation of 2.1 mm in the roll-bar region, and a minimum factor of safety of 1.3. In contrast, the Al 6061-T6 chassis exhibited a lower peak stress of 61 MPa at the rear wheel mounting region, a higher deformation of 3.4 mm at the roll bar, and a factor of safety of 4.5. The findings confirm a trade-off between stiffness and safety margin: steel offers higher stiffness but an insufficient safety margin, while aluminium significantly improves the static safety margin with increased deformation. These results provide design guidance for reinforcing critical regions and enhancing the robustness of competition-ready chassis.

Abstract

Formula SAE regulations require every prototype vehicle to be equipped with an impact attenuator as a passive safety system capable of absorbing a minimum frontal impact energy of 7,350 J at an impact velocity of 7 m/s for a vehicle with a mass of approximately 300 kg. This study aims to design an impact attenuator that satisfies the Formula SAE requirements to improve vehicle crashworthiness. Three design variations were analyzed using Finite Element Analysis (FEA) with LS-DYNA to evaluate energy absorption, impact force, acceleration/deceleration, and displacement. The accuracy of the numerical model was validated using previously published experimental data before analyzing the effect of thickness variation in each stage of the impact attenuator. The simulation results show that the optimum design is capable of absorbing impact energy above the minimum requirement of 7,350 J, exhibits a high Crash Force Efficiency (CFE), produces acceleration within the prescribed safety limits, and provides controlled deformation during the impact process. The results indicate that the proposed impact attenuator design satisfies the Formula SAE safety requirements and has the potential to be applied to prototype vehicles to improve safety performance during frontal collisions.
