Abstract

Rendahnya keaktifan dan hasil belajar siswa kelas XI TSM pada mata pelajaran Teknik Sepeda Motor menjadi permasalahan utama akibat dominasi metode konvensional yang cenderung pasif. Penelitian ini bertujuan meningkatkan keaktifan dan hasil belajar melalui penerapan model Problem Based Learning (PBL) pada materi perawatan dan perbaikan sasis sepeda motor. Penelitian menggunakan pendekatan kuantitatif dengan desain Penelitian Tindakan Kelas (PTK) dua siklus. Hasil penelitian menunjukkan peningkatan keaktifan siswa dari 47,36% pada siklus I pertemuan I menjadi 76,94% pada siklus II pertemuan II. Hasil belajar juga meningkat dari 36,67% pada pratindakan menjadi 83,33% pada siklus II. Temuan ini menegaskan bahwa PBL efektif mendorong partisipasi aktif, pemahaman mendalam, serta pencapaian akademik siswa dalam pembelajaran vokasi otomotif. The low learning activity and outcomes of class XI TSM students in Motorcycle Engineering subjects remain a major issue due to conventional teacher-centered methods. This study aims to improve student activity and learning outcomes through the application of the Problem Based Learning (PBL) model in motorcycle chassis maintenance and repair. A quantitative approach with a two-cycle Classroom Action Research design was employed. The findings show an increase in learning activity from 47.36% in cycle I meeting I to 76.94% in cycle II meeting II. Learning outcomes also improved from 36.67% in the pre-test to 83.33% in cycle II. These results demonstrate that PBL effectively enhances student engagement, deeper understanding, and academic achievement in vocational automotive education.

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh pemasangan catalytic converter aftermarket berbahan stainless steel (Brand KR 49 Racing, diameter 50 mm) terhadap kadar emisi gas buang karbon monoksida (CO) dan hidrokarbon (HC) pada sepeda motor Honda Beat FI seri KZL tahun 2014. 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.
