In Prosiding SNPF (Seminar Nasional Pendidikan Fisika). Pengembangan Instrumen Tes Kemampuan Memecahkan Masalah Fisika Berbasis Kearifan Lokal pada siswa SMP/MTs. It shows that the Honda CB150R engine operates on afr under the stoichiometry of the fuel used. As for the results of afr E50 ecu programable on the compression ratio 11 obtained an average value of 11.160, which means the condition of air and fuel mixture is under the afr stoikiometri is 12.6. Based on the results of au Eu ecu programable on the compression ratio 11 obtained an average value of 13.154 which means the condition of air and material mixture burn is under the afr stoichiometry ie 14.7. As for the ignition timing mapping is obtained in the range of 16 ° and 20 ° BTDC for the compression ratio of 12, 12.5, and 13. From this research, the exact mapping of injection mapping at 2000 to 4000 rpm is 150%, while at 5000 to 8000 rpm, the best duration is 125%. Then tested using Pertamax (0% bioethanol) under standard conditions as the control group and the use of Bioethanol E50 with variation of ignition timing as the test group by taking 4 variations of advance ignition timing 16 °, 20 °, 24 ° and 28 ° BTDC at compression ratio which has been converted to 12, 12.5, and 13. Thereafter the fuel injection testing to achieve AFR Bioethanol E50 with injection percentage of 100, 125, 150, 175 and 200 percent of the total fuel injection standard. This study focused on Honda CB150R engine with the initial setting on the ECU programmable. Thus, it is expected to increase the performance of the engine performance. In the application of bioethanol in combustion engines, it requires some modifications to the engine to be used such as changing the ignition time, changing the duration of the injection, changing the compression ratio, and modifying the engine fuel input system.
