The study aimed to find out the level of knowledge of seed production of forestry plantation crops at the beginning of lectures (pretest) and at the end of classes (posttest) for TIB Bogor and Sukabumi campus students to compare the pretest and posttest scores for these students as well as posttest scores between TIB campus students Bogor with TIB Sukabumi campus students. The research method used as a statistical test tool for the research data used to achieve the research objectives is the paired t-test, the Wilcoxon signed rank test, as the normality assumption test. The results showed an increase in the knowledge of TIB Bogor students during lectures based on the results of the pretest assessment compared to the posttest. Nearly 100% of the student’s understanding of seed production techniques for forestry plantation crops increased. In contrast to TIB Sukabumi students, the average posttest score of IPB Sukabumi vocational students was significantly higher than that of pretest me. This matter shows that lectures on seed production techniques for plantation and forestry plants still need to provide strong evidence of increasing knowledge about this for TIB Sukabumi students. So, it is necessary to do further research related to the factors that influence the lecture process. The average score of IPB Bogor students is higher than that of Sukabumi. It is suspected that there are differences in the factors that influence the attainment of this level of knowledge, such as differences in educational background, teaching quality, or student characteristics on both campuses.
