Abstract

The problem based learning model is a student centered learning strategy, which is an innovative that learning model provides active learning conditions . this study aims to measures the effectiveness of research articles on the application of the PBL model to improving science learning. this type of research is a meta- analysis using secondary and quantitative data to draw accurate conclusion in the form of effectiveness by searching the literature from the EBSCO database, Google Scolar and Taylor & Francis. Articles that have been published from 2019-2023. The keywords for cross - sectional studies are as follows: "Problem based learning " and " education " and " science learning outcomes ". The articles studied were full text articles with an observational research design. The articles were collected using the PRISMA diagram, and analyzed using the Reviews Manager 5.3 applications. Based on the results of the Forest Plot of 4 articles on learning with the application of the PBL Model, it has 1.09 units higher to get good learning outcomes compared to students who are given the application of the non PBL model (P<0.001; 95% Ci: 0.29 – 1.89; I2 = 94%).

Abstract

Coffee seedling production (Coffea spp.) is an important stage in supporting successful productive and sustainable coffee cultivation. However, scientific documentation on coffee seedling production techniques in a comprehensive manner at regional seed institutions, particularly at the UPTD Center for Certification and Seedling of Forest Plants of the Forestry Office of West Sumatra Province, remains limited. This study aims to describe the stages of coffee seedling production, identify supporting factors for seedling production success, and explain the criteria for quality coffee seedlings ready to be distributed to the community. This study used a descriptive qualitative approach with a field study design. Data were collected through participatory observation, interviews with nursery officers selected purposively, field practice, and activity documentation. The data were analyzed descriptively through the stages of data reduction, data display, and conclusion drawing. The results showed that coffee seedling production was carried out through the stages of seed selection, soaking for 24 hours, sowing in a soil and burnt rice husk medium with a ratio of 3:1, transplanting at the soldier–spear phase, and maintenance in polybags. Germination success reached 85–90%, with seedlings ready for distribution at the age of 4–6 months, a height of 20–30 cm, and 4–6 pairs of healthy leaves. The conclusion of this study affirms that systematic coffee seedling production through seed selection, the use of appropriate planting media, and controlled maintenance can produce quality seedlings to support the development of coffee cultivation. The implications of this study provide practical contributions for regional seed institutions in strengthening technical standards for coffee seedling production and supporting the provision of quality seedlings for the community.
