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.

Abstract

The high unemployment rate in Nagari Sialang Gaung, reaching 30–40% of the productive-age population, poses a serious problem hindering community welfare. This situation is paradoxical given the significant opportunities in the motor vehicle service sector, driven by an estimated 10% annual increase in the number of motorcycles. Unfortunately, this market potential remains largely untapped due to the lack of technical and entrepreneurial skills among the unemployed youth. The Prodi and Nagari Integration Program (PIPN) Life Skill was established to bridge this gap with a dual objective, enhancing motorcycle mechanic competence and fostering entrepreneurship through hands-on practice. The program was comprehensively designed, encompassing needs analysis, development of a curriculum based on local potential, technical training (covering both conventional and EFI injection systems), instruction in workshop management, and post-training business mentoring. Program results indicate a significant increase in participant competence, with 85% demonstrating the ability to perform repairs independently and 30% having successfully initiated small-scale repair businesses. This success underscores the critical importance of synergy between universities and village governance in empowering communities based on sustainable local potential, thereby contributing directly to the achievement of the Sustainable Development Goals (SDGs).

Abstract

The development of lightweight electric cars for urban mobility requires efficient aerodynamic design without sacrificing space efficiency. This study presents a novel method by investigating the combination of a two-seater city car's compact dimensions and square back shape, which has not been extensively researched for low- to medium-velocity vehicles. This study's objective is to assess the design's aerodynamic performance using numerical simulations using the Computational Fluid Dynamics (CFD) approach. The vehicle model is designed with a compact body and square back, which is commonly used in small vehicles with high maneuverability requirements. The simulations are conducted at three different air velocity levels: 10, 20, and 30 m/s. The results of the study showed an increase in the value of the drag coefficient (Cd) along with an increase in flow velocity. At a velocity of 10 m/s, the Cd value was recorded at 0.4536. When the velocity increased to 20 m/s, the drag coefficient increased slightly to 0.4563. Further increases in velocity to 30 m/s resulted in a Cd value of 0.4581. This Cd value shows the consistency of aerodynamic performance with increasing velocity, with fluctuations that remain within the efficiency limits of lightweight vehicles. The pressure distribution contour shows high-pressure accumulation at the front and low pressure at the rear of the vehicle, which generates large turbulent wakes in the rear area and contributes to increased drag. These findings indicate that the square rear body design faces significant aerodynamic challenges. Therefore, design strategies such as adding a rear spoiler, using a rear diffuser, and optimizing the rear body angle are suggested as potential solutions to improve flow efficiency.

Abstract

SMK memiliki peran dalam peningkatan kecerdasan, pengetahuan, kepribadian, akhlak mulia, dan keterampilan sebagai bekal untuk hidup mandiri dan siap kerja. Tamatan SMK diharapkan mempunyai kompetensi yang baik agar siap pakai dan terampil, sehingga memudahkan industri untuk medapatkan tenaga kerja sesuai posisi yang kebutuhan. Tetapi berdasarkan data BPS pada Agustus 2020, TPT SMK adalah 8,49% dan tertinggi dibandingkan jenjang pendidikan lainnya. Masalah ini terjadi karena belum selarasnya antara kompetensi tamatan SMK dengan kebutuhan industri. Penyelarasan kompetensi tamatan SMK terhadap kebutuhan industri tergantung pada sumber daya serta sarana/prasarana yang dimiliki SMK. Permasalahannya sarana/prasarana praktik yang dimiliki SMK masih sedikit dan kondisinya kurang memadai. Tamatan SMK Jurusan Teknik Sepeda Motor seharusnya memiliki pengetahuan dan keterampilan teknologi programmed fuel injection sepeda motor. Maka kegiatan ini bertujuan meningkatkan kompetensi siswa SMK melalui rancang bangun simulator dan pelatihan teknologi programmed fuel injection sepeda motor. Berdasarkan evaluasi pelaksanaan kegiatan, terdapat peningkatan kompetensi siswa tentang teknologi programmed fuel injection sepeda motor, sehingga diharapkan kualitas tamatan SMK Jurusan Teknik Sepeda Motor semakin baik dan dapat menurunkan TPT tamatan SMK.
