Article history Received: 25 September 2019 Revised: 26 June 2020 Accepted: 5 October 2020 This research aims to determine the effect of wimba learning strategies with PjBL (project-based learning) models toward student learning outcomes on the excretory system material. This research was conducted in September 2018 until September 2019. The research method used a true experiment with a population of all class XI in one of the State High School of Tasikmalaya City Indonesia, with eight classes with 288 students. The samples used were two classes taken by random cluster sampling, namely XI mathematics and science 1 (XIMS-1) class with 36 students (M=18, F=18) as a controller class and XI mathematics and science 4 class with 36 students (18 student male and 18 student female) as an experimental class. The research instrument was in the form of a multiple-choice written test totaling 30 questions. Based on the study results, data analysis using the ANCOVA test showed that the wimba learning strategy with the project-based learning model significantly improves students' understanding and analyzing concepts of the excretory system with p-value 0,002. These results are viewed from indicators of learning outcomes. The average score of N-Gain learning outcomes of students in the experimental class on the cognitive aspects of C1, C2, C4, and C5 have N-Gain better than the control class. This learning strategy was appropriate for learning biology that can make students more active in the learning process.
