Abstract

Abstrak: Penggunaan biofuel pada mesin kendaraan sudah banyak diapliaksikan sebagai bentuk penanggulangan krisis bahan bakar. Teknologi mesin pun berkembang guna menyesuaikan penggunaan biofuel. SMK berperan dalam mencetak lulusan yang siap kerja dengan menyesuaikan kebutuhan industri. Oleh karena itu, perlu adanya pelatihan perawatan mesin berbahan bakar biofuel bagi siswa jurusan Teknik Sepeda Motor SMK Muhammadiyah Kramat. Hal ini bertujuan agar siswa memiliki kompetensi perawatan mesin berbahan bakar bifuel sehingga siswa setelah lulus dapat bersaing didunia kerja khususnya dibidang mekanik sepeda motor. Pelatihan ini dilaksanakan dengan jumlah peserta sebanyak 22 siswa jurusan Teknik dan Bisnis Sepeda Motor. Pelatihan ini menggunakan metode ceramah dengan materi pengertian biofuel, karakteristik bahan bakar, prinsip kerja biofuel dalam proses pembakaran dan efek penggunaan biofuel pada mesin. Metode lainnya adalah demontrasi tentang cara kerja sistem injeksi berbahan bakar biofuel dan penggunaan scaner EFI untuk diagnosa kerusakan mesin. Diakhir kegiatan dilakukan evaluasi dalam bentuk post-test dan penilaian praktikum. Hasil evaluasi menunjukan bahwa nilai siswa mengalami peningkatan setelah mengikuti pelatihan pada setiap indikator capaiannya. Rata-rata peningkatan nilai indikator capaiannya adalah 54% dan seluruh siswa yang mengikuti pelatihan dinyatakan kompeten. Abstract: The use of biofuel in vehicle engines has been widely applied as a form of overcoming the fuel crisis. Engine technology has also developed to adjust the use of biofuel. Vocational schools play a role in producing graduates who are ready to work by adjusting to industry needs. Therefore, biofuel engine maintenance training needs to be provided for students majoring in motorcycle engineering at Muhammadiyah Kramat Vocational School. This aims to ensure that students have the competence to maintain biofuel engines so that after graduating students can compete in the world of work, especially in motorcycle mechanics. This training was carried out with 22 participants majoring in Motorcycle Engineering and Business. This training uses a lecture method with material on the definition of biofuel, fuel characteristics, the working principles of biofuel in the combustion process, and the effects of using biofuel on engines. Another method is a demonstration of how the biofuel injection system works and the use of an EFI scanner to diagnose engine damage. At the end of the activity, an evaluation was carried out in the form of a post-test and practical assessment. The evaluation results showed that student scores increased after participating in the training on each of their achievement indicators. The average increase in the achievement indicator score was 54% and all students who participated in the training were declared competent.

Abstract

Abstrak: Lulusan vokasi seperti Sekolah Menengah Kejuruan (SMK) menjadi penyumbang terbesar angka pengangguran. Fenomena ini bertolak belakang dengan orientasi pembelajaran yang diterapkan yang menggunakan metode praktikum berbasis project based learning (PBL). SMK Jurusan Teknik Sepeda Motor adalah jurusan yang memiliki potensi penyerapan tenaga kerja terbesar dengan mempertimbangkan fenomena volume kendaraan bermotor yang terus meningkat. Program Pengabdian ini bertujuan meningkatkan kompetensi sepeda motor bagi siswa Teknik Sepeda Motor SMK Muhammadiyah Kramat Kabupaten Tegal. Metode yang digunakan adalah PBL yang diterapkan melalui Workshop propertis bahan bakar dan Workshop Karakteristik bahan bakar. Kegiatan dilaksanakan pada tanggal 21 Juni 2024 bertempat di bengkel Teknik Sepeda Motor SMK Muhammadiyah Kramat Kabupaten Tegal yang diikuti 20 siswa kelas XI. Berdasarkan hasil evaluasi, siswa kelas XI memperoleh peningkatan kompetensi sepeda motor dengan prosentase 20%. Hal ini ditunjukkan dari hasil pengukuran kompetensi awal melaluisi pada PreTest dengan capaian penguasaan sebesar 68% dan meningkat menjadi 88% melalui pengukuran pada evaluasi PostTest. Pemberian materi propertis bahan bakar, performa dan karakteristik bahan bakar yang dilakukan melalui workshop dengan metode PBL terbukti dapat terserap secara maksimal.Abstract: Vocational graduates such as Vocational High Schools (SMK) are the largest contributors to unemployment. This phenomenon is in contrast to the applied learning orientation which uses a practical method based on project based learning (PBL). SMK Motorcycle Engineering Department is a department that has the greatest potential for absorbing labor considering the phenomenon of the increasing volume of motorized vehicles. This Community Service Program aims to improve motorcycle competence for Motorcycle Engineering students at SMK Muhammadiyah Kramat, Tegal Regency. The method used is PBL which is implemented through the Fuel Properties Workshop and Fuel Characteristics Workshop. The activity was carried out on June 21, 2024 at the Motorcycle Engineering workshop of SMK Muhammadiyah Kramat, Tegal Regency which was attended by 20 class XI students. Based on the evaluation results, class XI students obtained an increase in motorcycle competence with a percentage of 20%. This is shown from the results of the initial competency measurement through the PreTest with a mastery achievement of 68% and increasing to 89% through measurements in the PostTest evaluation. The provision of material on fuel properties, performance and fuel characteristics carried out through workshops using the PBL method has proven to be maximally absorbed.
