This study aims to obtain a standard project-based chemistry practicum guidelines for XI grade natural science program students of senior high school on solubility and solubility product (.sp) materials. The sample of population consisted of 3 chemistry practicum guideliness (publishers A, B, and C), 2 chemistry lecturers, 2 chemistry teachers, 2 classes of XI grade of natural science program. The research is descriptive, developmental and experimental by engaging ADDIE method. The results of standardization by teachers and lecturers on the A, B, C practicum guideliness, and the developed practicum guideliness obtained an average of 3.14, respectively; 3.32; 3.11; and 3.78. The practicum guidelines trial obtained by the experimental class was higher than control class (88.00% > 80.00%) and the activity value (performance) of the experimental class students was higher than the control class. Post-test data were analyzed by one-sided t-test at = 0.05, obtained t-count = 6.4 > t-table = 1.67. These results confirm that the project-based chemistry practicum guideliness that has been developed is good and meet the standard issued by BSNP (National Education Standard Board). Moreover, it is suitable to be used in learning chemistry at senior high school. © 2023 American Institute of Physics Inc.. All rights reserved.
