<![CDATA[Penggunaan bahan bakar minyak yang terus meningkat yang dapat menyebabkan kelangkaan bahan bakar. Sehigga perlu ada inovasi bahan bakar alternatif yaitu dengan bahan bakar hidrogen. Hidrogen berasal dari hidrolisis air menjadi hidrogen dan oksigen. Proses hidrolisis membutuhkan tegangan dan arus listrik yang besar, oleh karena itu perlu adanya energi tambahan dengan memanfaatkan gas buang dengan memberi turbin yang dihubungkan pada poros alternator agar menghasilkan tegangan dan arus listrik agar dapat mensuplai tegangan dan arus listrik dalam penggunaan bahan bakar hidrogen. Penelitian ini dimulai dengan merancang sebuah alternator sepeda menjadi turbin angin sumbu vertikal dengan perlakuan baling-baling tipe savonius dan tipe cross flow, pengujian dengan kecepatan kendaraan 30 sampai 60 Km/Jam. Disimpulkan perlakuan baling-baling cross flow meningkatkan tegangan 12,5% dan peningkatan arus 50,6% terhadap perlakuan baling-baling tipe savonius. Increasing fuel oil consumption can result in a petroleum shortage. Therefore, innovation in alternative fuels, specifically hydrogen fuel, is required. Hydrogen is produced by splitting water into hydrogen and oxygen. The hydrolysis process requires a large voltage and electric current; therefore, it is necessary to have additional energy by utilizing exhaust gas by connecting a turbine to the alternator shaft to produce voltage and electric current in order to provide voltage and electric current for the use of hydrogen fuel. This research begins with the design of a bicycle alternator as a vertical axis wind turbine with savonius type and cross flow propeller treatment, tested at velocities between 30 and 60 kilometers per hour. It was determined that the cross flow propeller treatment increased the voltage by 12.5% and the current by 50.6% compared to the savonius propeller treatment.]]>

<![CDATA[The main aim of SMK is to prepare students to have the practical skills and knowledge needed to enter the world of work. After completing education at vocational school, students can immediately work or choose to continue their education to a higher level. The alignment between the vocational school curriculum and industry demands, especially in graduate skills training (link and match), is currently not yet optimal so it is not adequate to meet the needs of the world of work, industry and business. Even though certain efforts and policies have been made, there are still a number of problems faced by vocational school students. At SMKN 1 Koto Baru, one of the fundamental problems that need special attention in learning is the lack of availability of Electronic Fuel Injection (EFI) competencies. This skill is a very important competency, especially in the Motorcycle Engineering and Business (TBSM) program. The results of observations in schools show that practical equipment for both teachers in the teaching process and for students as practical objects is sufficient and always updated. This happens because SMKN 1 Koto Baru has workshop and laboratory facilities which are equipped with adequate equipment. Apart from that, the instruments used in the practicum are good and can be operated according to the standards they should be. Therefore, training was carried out on the use of the smart simulator to increase learning activities because it involved technology in this training which provided new experiences to students. From the results of the activity, it can be seen that students are very enthusiastic and have increased activity in learning because they can carry out a more complete and clear exploration of learning about the EFI system on motorbikes]]>

<![CDATA[Hole injector memiliki peran terhadap campuran bahan bakar di ruang bakar. Penelitian ini bertujuan untuk mengetahui penggunaan hole injector variasi terhadap konsumsi bahan bakar, top speed, dan emisi gas buang pada sepeda motor type matic. Metode eksperimen dilakukan dengan membandingkan penggunaan hole injector standar (6 lubang) dan hole injector variasi (8 lubang). Data penelitian secara langsung diambil dari kinerja sepeda motor Honda Beat Street kemudian disajikan dengan metode deskriptif persentase. Hasil penelitian berupa konsumsi bahan bakar, top speed, dan emisi gas buang berhasil diperoleh dan dianalisa lebih lanjut. Dari analisa dapat disimpulkan bahwa injector variasi 8 lubang memiliki hasil yang tidak baik karena konsumsi bahan bakar menjadi boros dan peningkatan emisi gas buang. Sehingga penggunaan injector ini tidak direkomendasikan untuk digunakan pada sepeda motor matic. Hole injectors have a role in the fuel mixture in the combustion chamber. This study aims to determine the usage of hole injector variations on fuel consumption, top speed, and exhaust emissions on matic type motorbikes. The experimental method was carried out by comparing the use of standard hole injectors (6 holes) and hole injector variations (8 holes). Research data was directly taken from the performance of Honda Beat Street motorbike and then presented with descriptive percentage method. The research results in the form of fuel consumption, top speed, and exhaust emissions were successfully obtained and further analyzed. From the analyses it can be concluded that the 8-hole variation injector has poor results due to wasteful fuel consumption and increased exhaust emissions. So the use of this injector is not recommended for use on matic motorbikes.]]>
