PENGARUH PENGGUNAAN ELEKTROLISER KAWAT TEMBAGA DAN JENIS BUSI TERHADAP EMISI GAS BUANG CO DAN HC PADA SEPEDA MOTOR HONDA BEAT TAHUN 2010

Purposes of the research are: (1) to do research  effect of copper wire electrolyzer on CO and HC exhaust gas emission of Honda Beat motorcycle of 2010. (2) To do research  effect of sparkplug type on CO and HC exhaust gas emission of Honda Beat motorcycle of 2010. (3) To do research  interactive effect using  copper wire electrolyzer and type of sparkplug on CO and HC exhaust gas emission of Honda Beat motorcycle of 2010. The experiment uses 4x3 factorial method and quantitative approach. Population of the research is Honda Beat motorcycle of 2010. Sample of the research is Honda Beat motorcycle with machine-number JF51E1050768. Sample is taken by using purposive random sampling technique. Based on the data analysis, it can be concluded that: (1) There were effect using copper wire electrolyzer on CO and HC exhaust gas emissions of Honda Beat motorcycle of 2010 and from the data presented indicate that the levels emissions of CO and HC were lower than before using electrolyzer. (2) There were effect using types of sparkplugs on CO and HC exhaust gas emissions of Honda Beat motorcycle of 2010 and from the data presented indicate that the levels emissions of CO and HC were lower than using the standard sparkplug. (3) There were interactive effect using electrolyzer and sparkplug type on CO and HC exhaust gas emission of Honda Beat motorcycle of 2010 and shows the exhaust emissions of CO and HC more lower

BUKU DIGITAL INTERAKTIF SISTEM AIR CONDITIONING (AC): UPAYA MEMBELAJARKAN SISWA PADA MASA PANDEMI COVID-19 DI DAERAH YANG MISKIN SINYAL SELULER.

Indonesia in the 2019 PISA report for reading scores has fallen far from the previous, which is ranked 72 out of 79 countries (Hewi & Shaleh, 2020). One of the external factors that influence is the learning process. Interactive Digital Book (BUDIN) is an alternative media that can be used to increase students' reading interest (Rosyadi & Santosa, 2019). The research objective was to determine the increase in the reading intensity of students through the BUDIN air conditioning system as well as an alternative learning process during the Covid-19 pandemic that could be used in areas with poor cellular signal. The method in this research is using survey explanatory method. Data analysis was carried out by descriptive analysis (A. Muhidin and Maman A, 2007: 53). BUDIN air conditioning system is intended for students in class XI automotive engineering expertise program.From the research results, it was found that independent learning using BUDIN increased reading intensity from before. It can be seen that after using BUDIN, the reading intensity has increased. The reading intensity of the very high category rose to 16%, then the high category increased to 47%. While the reading intensity of the moderate category decreased to 25% of students, as well as students in the low category, it decreased to 12% of students from the previous 38% of students
