This research aim to know the effectiveness of using chemsketch on the teaching molecular shape of hydrocarbon to increase student achievement. Hydrocarbon is very interesting to be discussed. Technology utilized need to solve this problem which is by using chemsketch. Chemsketch implemented by powerpoint. Research conducted in SMAN 5 Medan sample that used consists of two classes, that consist of experiment class and control class. The average pretest score in control is 33.33 and posttest score is 73.03. Percentage of passed students post-test is 69.70% from 33 students only 23students. While experiment class average pretest score is 32.12 and posttest score is 81.21. Percentage of passed students post-test is 85.71%, from 35 students only 30 students. The gain percentage between the post-test score in the experiment and the control class is 16.01%. The result showed that chemsketch with PowerPoint effective to increase student’s achievement in hydrocarbon and suitable following industrial revolution 4.0 to prepare student face globalization era education.
