Abstract

Perguruan Tinggi mempunyai peran penting dalam Tri Darma, yaitu ikut dalam mencerdaskan kehidupan bangsa dan negara sencara nyata di masyarakat. Salah satu langkahnya adalah menjadikan manusia bukan lagi menjadi obyek pembangunan tetapi menjadi subyek pembangunan. Sebagai subyek pembangunan tentunya diperlukan kemampuan dan kecakapan dalam penguasaan ilmu pengetahuan dan teknologi. Pemanfaatan teknologi pengelasan telah berkembang dan banyak digunakan  dan dimanfaatkan ditengah masyarakat luas, baik untuk skala industri rumah tangga maupun untuk perbaikan perbaikan peralatan dirumah. Salah satu metode pengelasan adalah pengelasan SMAW, yaitu pengelasan dengan menggunakan busur listrik.Tujuan dari kegiatan ini adalah meningkatkan pengetahuan secara umum remaja karang taruna kelurahan Temas Kecamatan Batu kota Batu, menambah ketrampilan kusus berupa pengelasan SMAW dan memberikan dorongan dan bantuan sehingga karang taruna kampung teh mampu mengadakan peralatan las.Manfaat dari kegiatan ini adalah  memberikan pengetahuan dan melatih ketrampilan dalam pengelasan SMAW sehingga bisa digunakan untuk pengembangan pribadi maupun manfaat secara sosial

Abstract

The significant increase in motorcycle production in August 2024 has reached 137,350,299, but there are still several obstacles that cause less than optimal engine performance. The study aims to analyze the effect of variations in the number of injector holes on power in a 110cc motorcycle. The approach used is a quantitative experimental type to reveal the effectiveness of using variations in the number of injector holes on power in a 110cc motorcycle engine. The sample used is a 110cc motorcycle, which is affected by four variations in the number of injector holes 4, 6, 8, 10. The results of the study show that the highest power of 6.43 HP and 7.80 Nm is obtained from hole 4 using RON 95 fuel, meaning that H0 is rejected and H1 is accepted, meaning there is a significant influence between the number of injector holes and the type of fuel on the power of a 110cc motorcycle.

Abstract

Motorcycles are the most widely used vehicles in Indonesia due to their practicality, especially those with automatic transmissions. However, the increasing number of motorcycles, particularly in East Java Province, has contributed significantly to air pollution through exhaust gas emissions. This study aims to analyze the effect of injector hole variation and fuel octane rating (RON) on exhaust emissions and in 110cc gasoline motorcycles. The method involves laboratory testing with injector hole variations (4, 6, 8, 10) and the use of Shell RON 92 and RON 95 fuels. The observed variables include exhaust emissions (CO and HC) and specific fuel consumption, with engine temperature controlled at 80–85°C and fuel pressure at 43 psi. The results show that the configuration of a 6-hole injector with RON 95 produces the lowest emission values, with CO at 0.02% and HC at 84 ppm, meeting the Indonesian Ministry of Environment and Forestry’s emission standards (CO ≤ 3%, HC ≤ 1000 ppm), while also achieving the most efficient fuel consumption across all RPM ranges.
