The purpose of this classroom action research was to determine the increase outcome because of using chemical compounds system cards methods. This method was used on the 35 X-C Class students in SMAN 3 South Jakarta. This research included a description of the research carried out by two cycles where every single cycle consists of 3 times meeting hour and each cycle consisting of planning,, observation and reflection with action approach research. The results of description analysis revealed, with the following data:First cycle, average achievement of chemical material chemical nomenclature is 73. 14, the percentage of completeness 42%, and the second cycle, the average results of studying chemistry has increased to 81 with a percentage of 90%, the percentage of active learners in the classroom are:First cycle average percentage of active learners from 58. 82% to 82. 56% in the second cycle. Thus, it can be concluded that the results of the chemical study of the nomenclature of chemicalcompounds can be enhanced by using chemical system cards method on 3 Senior High School XC Class 3 student atthe South Jakarta Setiabudi II
