Abstract

Kebutuhan energi di Indonesia saat ini masih didominasi oleh energi yang berbasis bahan bakar fossil, seperti minyak bumi dan batu bara. Kerugian dari bahan bakar fosil adalah sifatnya yang tidak ramah lingkungan. Air adalah sumber energi alternatif yang dapat menggantikan sumber energi berbasis fosil dan merupakan energi terbarukan. Turbin Archimedes Screw merupakan turbin yang cocok digunakan di Indonesia yang mempunyai aliran sungai dengan head rendah. Penelitian ini menggunakan metode eksperimen, yaitu merancang dan membuat turbin Archimedes Screw. Hasil pengujian selama 180 menit dari ketiga model turbin Archimedes screw, yaitu tipe ulir 1 menghasilkan tegangan 2,83 volt, tipe ulir 2 menghasilkan tegangan 3,16 volt dan tipe ulir 3 menghasilkan tegangan 2,49 volt. Tipe ulir 2 yang bisa menghasilkan tegangan lebih besar selama 180 menit yaitu 3,16 volt.

The community service carried out at SMK Negeri 1 Kotanyar is a form of implementation of the Tridharma of Higher Education by providing assistance as well as serving as an external examiner in the Skills Competency Test. This Community Service Program focuses on activities carried out on the Automotive Light Vehicle Engineering skills program with material including Tune Up, Chassis, Automotive Electrical, and AC (Air Conditioning) Systems. The results of the skills competency test are given a weight that has been regulated in the assessment rubric, namely 70% for the skills aspect and 30% for the knowledge aspect. Based on the results of the exams carried out by all participants, it can be seen that the recapitulation of the Skills Competency Test results at SMK Negeri 1 Kotaanyar shows that the overall average of students at SMK Negeri 1 Kotaanyar received a final score of "Competent" in the field of light vehicle engineering expertise. automotive.
