Abstract

Sepeda motor matic awalnya dirancang untuk pengguna wanita dengan desain yang praktis, hemat bahan bakar, dan efisien. Penelitian ini bertujuan untuk menganalisis pengaruh modifikasi kemiringan Primary Sliding Sheave terhadap torsi, daya, dan top speed pada Yamaha Mio M3 125. Metode yang digunakan adalah eksperimen dengan Dynotest untuk mengukur performa kendaraan sebelum dan sesudah modifikasi. Hasil penelitian menunjukkan bahwa modifikasi kemiringan Primary Sliding Sheave meningkatkan torsi dan daya secara signifikan, serta memungkinkan pencapaian top speed dalam waktu yang lebih cepat dibandingkan dengan sudut standar. Matic motorcycles were originally designed for female users with a practical, fuel-efficient, and efficient design. This research aims to analyze the effect of Primary Sliding Sheave tilt modification on torque, power, and top speed on Yamaha Mio M3 125. The method used is experimentation with Dynotest to measure vehicle performance before and after modification. The results showed that the Primary Sliding Sheave tilt modification increased torque and power significantly, and allowed the achievement of top speed in a faster time compared to the standard angle.

Abstract

Studi penelitian ini dilakukan untuk melihat bagaimana penambahan zat aditif minyak serai wangi dan minyak cengkeh mempengaruhi emisi gas buang dari sepeda motor Honda Beat FI tahun 2019. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan penambahan zat aditif minyak serai wangi dan minyak cengkeh terhadap emisi gas buang. Jenis penelitian ini disebut juga sebagai penelitian eksperimen. Sepeda motor Honda Beat FI 2019 adalah objek penelitian ini. Berdasarkan penelitian pada sepeda motor Honda Beat FI tahun 2019, bahwa hasil perhitungan T test untuk emisi gas buang nilai T hitung = 6,276 sedangkan T tabel = 2,776, berarti t hitung > t tabel, sehingga dengan menambahkan bahan tambahan seperti minyak serai wangi dan minyak cengkeh terdapat perbedaan yang signifikan dengan penambahan minyak sereh wangi 10 % dibandingkan dengan penambahan minyak cengkeh 15 %. This research was conducted to analyze the comparison of the addition of citronella oil additives and clove oil to exhaust emissions produced by Honda Beat FI motorbikes in 2019. The purpose of this study was to determine the difference in the addition of citronella oil additives and clove oil to exhaust emissions. This type of research is also known as experimental research. The object of this research is the 2019 Honda Beat FI motorcycle. Based on the results of research conducted on Honda Beat FI motorcycles in 2019, that the results of the T test calculation for exhaust emissions the value of T count = 6.276 while T table = 2.776, means t count> t table, so that with the addition of citronella oil additives and clove oil there is a significant difference with the addition of 10% citronella oil compared to the addition of 15% clove oil.

Abstract

Penelitian dilatar belakangi kurangnya media pembelajaran pada mata pelajaran pemeliharaan kelistrikan kendaraan ringan di SMK Negeri 1 Bukittinggi. Tujuan penelitian merancang media pembelajaran berupa simulator sistem pengisian IC Regulator yang digunakan oleh guru dan siswa dalam proses belajar. Penelitian ini memakai metode penelitian dan pengembangan model (4-D). Hasil Penelitian dilihat dari hasil uji validitas dan pratikalitas yang diperoleh dari ahli dan responden. Berdasarkan hasil uji validitas dari ahli media tingkat pencapaian skor sebesar 93% pada kategori “sangat valid. Ahli materi 91% pada kategori “sangat valid. Hasil uji praktikalitas oleh guru didapatkan tingkat pencapaian skor 94% pada kategori “sangat praktis” dan dari siswa 88% pada kategori “praktis”. Disimpulkan bahwa media pembelajaran simulator sistem pengisian IC Regulator yang telah dibuat pada kategori sangat valid dan praktis. This research was motivated by the lack of learning media on the subject of light vehicle electrical maintenance at SMK Negeri 1 Bukittinggi. The aim of the research is to design learning media in the form of an IC Regulator charging system simulator that is used by teachers and students in the learning process. This research uses research and model development methods (4-D). The research results were seen from the results of validity and practicality tests obtained from experts and respondents. Based on the results of media expert validity tests, the score achievement level was 93% in the "very valid" category. Material experts 91% in the "very valid" category. The results of the practicality test carried out by the teacher showed an achievement level of 94% in the "very practical" category and 88% of students in the "practical" category. It was concluded that the IC Regulator charging system simulator learning media that had been created was in the very valid and practical category.
