Abstract

Penelitian ini membahas kualitas pelayanan jasa body repair sebagai faktor penting dalam peningkatan kepuasan konsumen pada PT Otobodi Mitra Sumatera. Metode yang digunakan adalah survei kuantitatif dengan pendekatan SERVQUAL pada lima dimensi, yaitu tangible, reliability, responsiveness, assurance, dan empathy, melalui penyebaran kuesioner kepada 50 responden (purposive sampling). Data dianalisis dengan menghitung rata-rata harapan (E) dan persepsi (P), kemudian nilai gap (P−E) pada tingkat atribut dan dimensi. Hasil menunjukkan bahwa nilai gap dimensi secara umum masih negatif dengan gap terbesar pada tangible (−1,23), diikuti reliability (−1,11) dan responsiveness (−0,97), sementara assurance bernilai −0,35 dan empathy positif 0,10; rata-rata gap per dimensi sebesar −0,712. Temuan ini mengindikasikan bahwa peningkatan kepuasan perlu diprioritaskan pada aspek bukti fisik (tangible), keandalan (reliability), dan daya tanggap (responsiveness), sementara dimensi empati (empathy) dipertahankan karena telah memenuhi atau melampaui harapan pelanggan. This study examines body repair service quality as a key driver of customer satisfaction at PT Otobodi Mitra Sumatera. A quantitative survey was conducted using the SERVQUAL framework across five dimensions—tangible, reliability, responsiveness, assurance, and empathy—by distributing questionnaires to 50 purposively selected customers. The analysis computed mean expectations (E) and perceptions (P) and derived the service quality gap (P−E) at both attribute and dimension levels. The results indicate predominantly negative dimension gaps, with the largest gaps in tangible (−1.23), followed by reliability (−1.11) and responsiveness (−0.97), while assurance shows a smaller negative gap (−0.35) and empathy shows a positive gap (0.10); the average gap across dimensions is −0.712. These findings imply that improvement efforts should prioritize tangible, reliability, and responsiveness, while maintaining strengths in empathy to sustain a positive customer experience.

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.
