Abstract

Aliran gas buang pada kendaraan memiliki potensi untuk kemudian dimanfaatkan kembali menjadi sumber energy baru pada kendaraan. Potensi energy ini dapat berupa pemanfaatan panas (thermal), tekanan (pressure) dan kecepatan aliran gas buang. Pada artikel ini khusus membahas dimana posisi konsentrasi pressure, velocity dan temperature gas buang yang terjadi. Data ini kemudian dapat dijadikan acuan dalam merancang dan menentukan jenis dan tipe mekanisme pemanen energy gas buang pada kendaraan. Input variable penelitian ini Temperature gas buang yang akan memasuki exhaust manifold diatur 15000K, tekanan gas buang yang memasuki exhaust manifold diatur 2 bar atau 200000 Pa, inlet mass flow 0.01kg/s, inlet volume flow 0.001m3/s, inlet velocity 3.143m/s, Berdasarkan hasil simulasi yang dilakukan dari segi aspek velocity aliran tertinggi dapat kita manfaatkan pada posisi pengukuran pada titik ukur 3, untuk temperature tertinggi dapat kita lihat pada titik ukur 2.

Abstract

Traffic accidents are one of the highest causes of death in Indonesia. One of the factors traffic accidents is caused by vehicles, in this case the braking system. Brakes are a device on a vehicle that functions to reduce the speed by applying friction. The main feature in the braking system is heat dissipation. If the brake overheating, the effectiveness of the braking system will be reduced. In general, there are two types of brakes, but in modern vehicles disc brake more used. In this study, various types of disc brakes will be tested. The designs tested are solid disc brakes, drilled-type disc brakes, and grooved-type disc brakes. The aim of research for determine the most optimal disc brake design. The temperature value on the surface of the disc brake will be measure. The Finite Element Analysis (FEA) method is used in this study. The validation process is carried out by comparing analytical result and Finite Element Analysis result on solid disc brakes. The speed before braking is 60 km / h. Material used on disc brake is grey cast iron. In the simulation process using Finite Element Analysis, the mesh size used is 3 mm and the number of elements is 255,244 elements. After the analysis was carried out, the temperature value in the grooved-type disc brake design was the smallest value than another with a maximum temperature of 143.56 ºC during braking. Thus, based on the results obtained, the grooved-type disc brake tends to be more optimal.

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

Drum brakes are one of the crucial components in motor vehicle braking systems, particularly in motorcycles, due to their advantages in production cost and resistance to environmental contamination. However, this type of brake has limitations in dissipating heat during braking, which can lead to temperature accumulation, thermal deformation, and reduced braking efficiency. This study aims to analyze the thermo-mechanical performance of drum brakes with various cooling groove designs (solid, straight-grooved, and slant-grooved) using a numerical method based on Finite Element Analysis (FEA) in ANSYS Workbench. The analysis was conducted in a transient manner, both thermally and structurally, to evaluate temperature distribution and total deformation for each design. The results show that the slant-grooved drum brake design yields the lowest temperature distribution and total deformation values, especially at high braking speeds, with a temperature distribution of 56.899 °C and total deformation of 17.67 × 10⁻³ mm. These findings indicate that groove design significantly affects the heat dissipation and structural deformation performance of the brake system. The study concludes that the slant-grooved design is superior in reducing heat and deformation, thereby offering the potential to improve braking safety and efficiency.

Abstract

The dwindling availability of fossil-based energy sources has spurred breakthroughs in the evolution of eco-conscious transportation, one of which is manifested in the Indonesian Electric Car Competition (Kompetisi Mobil Listrik Indonesia – KMLI). In this arena, collegiate teams engineer lightweight, single-occupant electric prototype vehicles emphasizing energy thrift. Nonetheless, spatial constraints and performance optimization frequently take precedence over ergonomic design, heightening the likelihood of musculoskeletal strain. This investigation seeks to examine bodily discomforts related to the musculoskeletal system as encountered by the operator of a prototype electric vehicle, employing the Nordic Body Map (NBM) assessment tool. The inquiry adopted a descriptive format via a focused case analysis involving the primary driver from the Megathrust Eco Team representing Universitas Negeri Padang (UNP) in the 2024 KMLI. Post-operation, the participant filled out the NBM form to denote discomfort regions, referencing a Likert-type scale from 1 (no pain) to 4 (extreme pain). The outcomes identified the cervical region, shoulders, dorsum, and lumbar zone as areas with elevated distress, classified under Pain and Intense Pain levels, thus revealing substantial ergonomic concerns. From these insights, it is inferred that the seating layout and cockpit geometry must be reconsidered and fine-tuned according to the driver’s anthropometric dimensions to alleviate physical complaints and boost vehicular comfort. The study aspires to aid in fostering electric vehicles that are more attuned to human-centered design, balancing well-being and operational safety.
