Abstract

The Competency Test for Teacher Professional Education Program Participants (UKPPPG) is an essential stage for assessing the professionalism of vocational teachers, including those in the field of automotive engineering. Adequate preparation is required to ensure that teachers meet competency standards while also improving the quality of learning in vocational schools. This study aims to describe the preparation strategies facilitated by the Automotive Engineering Subject Teacher Forum (MGMP) in West Sumatra and to identify the challenges teachers face in preparing for the UKPPPG. This research employed a descriptive qualitative approach with a case study design. The subjects consisted of 15 automotive teachers who were actively involved in MGMP activities and preparing for the UKPPPG. Data were collected through in-depth interviews, participatory observation, and document analysis. Thematic analysis was carried out through coding, theme identification, and verification using source and method triangulation. The findings indicate that MGMP preparation strategies include lesson plan development, microteaching, and exam discussions. These activities improved teachers’ pedagogical skills; however, limitations such as inadequate workshop facilities, conventional teaching materials, and the lack of computer-based simulations hindered optimal preparation. This study concludes that MGMP plays a significant role in preparing teachers for the UKPPPG, although its effectiveness remains limited to pedagogical aspects. A more comprehensive strategy involving curriculum renewal, access to updated materials, psychological support, and digital technology integration is needed.

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.

Metode yang digunakan adalah eksperimen dengan dua kondisi pengujian, yaitu knalpot standar tanpa catalytic converter dan knalpot dengan catalytic converter, pada tiga variasi putaran mesin (1600, 2500, dan 6000 rpm) dengan tiga kali pengulangan pada setiap kondisi. Emisi CO (%) dan HC (ppm) diukur menggunakan exhaust gas analyzer. Hasil menunjukkan bahwa pemasangan catalytic converter menurunkan rata-rata CO dari 5,16% menjadi 4,40% (1600 rpm), 0,93% menjadi 0,54% (2500 rpm), dan 0,51% menjadi 0,37% (6000 rpm). Rata-rata HC juga menurun dari 279 ppm menjadi 209 ppm (1600 rpm), 91 ppm menjadi 75 ppm (2500 rpm), dan 39 ppm menjadi 37 ppm (6000 rpm), dengan persentase penurunan rata-rata HC berturut-turut 25,08%, 17,58%, dan 5,12%. Temuan ini mengindikasikan bahwa catalytic converter berbahan stainless steel berpotensi menurunkan emisi CO dan HC pada konfigurasi pengujian yang digunakan. This study evaluates the effect of installing an aftermarket stainless-steel catalytic converter (Brand KR 49 Racing, 50 mm diameter) on carbon monoxide (CO) and hydrocarbon (HC) exhaust emissions of a 2014 Honda Beat FI KZL-series motorcycle. An experimental design was applied under two conditions: a standard exhaust without a catalytic converter and an exhaust equipped with the catalytic converter, tested at three engine speeds (1600, 2500, and 6000 rpm) with three repetitions per condition. CO (%) and HC (ppm) were measured using an exhaust gas analyzer. The results show that the catalytic converter reduced mean CO from 5.16% to 4.40% (1600 rpm), from 0.93% to 0.54% (2500 rpm), and from 0.51% to 0.37% (6000 rpm). Mean HC decreased from 279 ppm to 209 ppm (1600 rpm), from 91 ppm to 75 ppm (2500 rpm), and from 39 ppm to 37 ppm (6000 rpm), corresponding to mean HC reductions of 25.08%, 17.58%, and 5.12%, respectively. These findings indicate that a stainless-steel catalytic converter can reduce CO and HC emissions under the tested conditions.
