The research method uses Research and Development (R&D) done until limited testing phase. The test was conducted to 30 students of 10 th grade of SMA Negeri 1 Manyar-Gresik. Feasibility of a game based on the aspects of validity, practicality, and effectiveness. The validity aspects is obtained from the validity assessment by validator consisting of two chemistry lecturers and one chemistry teacher. Practicability aspects are obtained from student activities observations and student response questionnaire. Effectiveness aspect obtained from learning outcomes and student learning motivation. The results of the content validity obtained range percentage 86%-93% in a very valid category and construct validity obtained in the range of 66%-100% in a valid and very valid category. The results of student activities observations obtained range percentages 83% to 100% in very good categories and the results of student responses questionnaire obtained range percentages 83%-100% in very good categories. Students learning outcomes obtained classical completeness get percentage of 100% and the results of student learning motivation questionnaires obtained a percentage of 83%-93% in a very good category.

Software feasibility can be known by three aspects that are (1) software validity based on content and construct validity, (2) practicality based on student response questionnaire supported by student observation activities, (3) effectiveness based on shifting understanding of student conceptions from misconceptions to knowing the concepts. This research uses Research and Development (R&D) method based on Borg and Gall, with 12 subject that are the students of 11th grade at Senior High School 1 Pandaan, Pasuruan in Indonesia who have studied chemical equilibrium and have potential to misconception. The result shows that Demische software was used to detect and reduce misconception through conceptual change text strategy in chemical equilibrium which can be known by three aspects that are (1) the average percentage of content validity is 83,06% and construct validity is 85,60%, both of validity are categorized as highly valid; (2) the average percentage of student response is 91,11% and categorized as highly practical; (3) the average percentage of effectiveness based on shifting understanding of student conceptions from misconceptions to knowing the concepts is 84,92% and categorized as highly effective.
