This research aimed to determine the effect of the problem-based learning model on students' learning outcomes on the colloid topic. This research applied an experimental method with a quasi-experimental design using a pretest-posttest control group design. The sample in this study was conducted in one of the SMA in The Bone Bolango district. To determine the effect of the problem-based learning model on students' learning outcomes in the colloid topic, the researcher used a test in the form of an essay with five questions that have been tested for validity and reliability. In the meantime, the hypothesis testing in this study was carried out by employing a t-test. The results of hypothesis testing obtained that the tcount value of 7,7 was higher than 1,67649. Where H0 was rejected and Ha was accepted. Thus, it could be concluded that the problem-based learning model affected students' learning outcomes in the colloid topic. © 2023 The Authors.
