Abstract

Permasalahan dalam penelitian ini adalah kenyataan yang ditemukan dilapangan yaitu Pulsed Secondary Air Injection System (PAIR) yang digunakan di sepeda motor Suzuki Shogun 125 RR sangat dibutuhkan untuk mengurangi emisi gas buang pada sepeda motor jenis ini, namun sering terjadi pada masyarakat kita justru melepaskan komponen ini dengan alasan sering terjadinya ledakan pada sepeda motor.Desain penelitian ini menggunakan metode quasy eksperimen. Proses pengujian kandungan emisi gas buang khususnya CO dan HC dilakukan pada putaran 1200 RPM, 2500 RPM, dengan menggunakan sistem PAIR, Non PAIR, Tabung Induksi dan Tidak memakai sistem sebagai sampelnya. Proses pengujian dilakukan sebanyak 5 kali pada setiap aspek pengujian. Data di input dengan menggunakan Microsoft Exel 2017 dan dianalisis dengan menggunakan program SPSS versi 24. Berdasarkan analisis data hasil penelitian diperoleh Terjadi penurunan kadar gas CO pada penggunaan sistem PAIR sebesar 5,49% diputaran mesin 1200 RPM, sedangkan pada putaran mesin 2500 RPM penurunan kadar gas CO sebesar 0,29 %. dan pada Tabung Induksi terjadi penurunan CO diputaran mesin 1200 RPM sebesar 2,34%, sedangkan pada putaran mesin 2500 RPM penurunan kadar gas CO sebesar 2,96%. Terjadi penurunan kadar gas HC pada penggunaan sistem PAIR sebesar 213,2 PPM diputaran mesin 1200 RPM, sedangkan pada putaran mesin 2500 RPM penurunan kadar gas HC sebesar 32,8 PPM. dan pada Tabung Induksi terjadi penurunan HC diputaran mesin 1200 RPM sebesar 422,6 PPM, sedangkan pada putaran mesin 2500 RPM penurunan kadar gas HC sebesar 181,6 PPM.
