Abstract
This research aims to develop the objective test of conceptual knowledge on physics topic heat and temperature in Senior High School which fulfills the required qualifications (standard test) consisting of validity, reliability, level of difficulty, discrimination power, and distractor effectiveness. This research is developmental research using Borg and Gall research method development. In analyzing the data, the research used qualitative and quantitative techniques. The research result considered from qualitative analysis, the questions quality of the conceptual knowledge test is very good with 93% ideality. While from the quantitative analysis, the questions quality of the conceptual knowledge test is good. By analyzing the 75 items of the conceptual knowledge test, it was found that there were 72 approved items and 3 rejected questions. On the large group test, there were (1) 68 valid items (94.4%) and 4 invalid items (5.6%); (2) 0.950 as the good reliability of items; (3) based on the difficulty level, 3 easy items (4.2%), 63 average items (87.5%), and 6 difficult items (8.3%); (4) based on the discrimination power, 39 excellent items (54.2%), 28 good items (38.8%), 3 average items (4.2%), and 2 bad items (2.8%); 5) based on the distractor effectiveness, 68 effective items (94.4%) and 4 ineffective items (5.6%). Therefore, for the good quality items of conceptual knowledge, it was achieved that there were 65 approved items (90.2%), 3 revised items (4.2%), and 4 rejected items (5.6%).
