Abstract

This study aimed to determine the effect of liquid organic fertilizer derived from tomato waste and leucaena leaves on the growth and yield of pakcoy plants. The study was conducted for 35 days at Jl. Perjuangan Unmul, Sempaja Selatan, Samarinda Utara, Samarinda City, East Kalimantan Province. This research employed a true experimental design using a Randomized Block Design (RBD) consisting of four treatments: K0 (control), P0 (20%), P1 (40%), and P2 (60%), with six replications. The data were analyzed using one-way analysis of variance. The results showed that the plant height of pakcoy at 14 days after planting (DAP) was identical across all treatments, measuring 4 cm; therefore, it was not subjected to statistical analysis. Similarly, the number of leaves at 14 DAP was relatively uniform, with an average of five leaves per plant. At 21, 28, and 35 DAP, the analysis of variance indicated that the treatments had a significant effect on plant height, with calculated F values of 30.82, 32.44, and 25.33, respectively, which exceeded the critical F value (3.10). The treatments also had a significant effect on the number of leaves at 21, 28, and 35 DAP, with calculated F values of 10.00, 27.35, and 21.28, respectively. In addition, a significant effect was observed on fresh weight at harvest, with a calculated F value of 133.66, which exceeded the critical F value (3.10). These findings indicate that the P1 treatment (40%) was the most effective concentration in enhancing the growth of pakcoy plants compared to the other treatments.

Abstract

This research investigates the impact of applying a problem-based learning (PBL) model supported by poster media on the learning outcomes of eleventh-grade students at SMAN 2 Unggulan Tanah Grogot. The integration of posters within the PBL approach is intended to enhance student engagement in biology lessons by presenting authentic problems that encourage critical and creative thinking. A quasi-experimental method was employed involving two groups: an experimental group taught using the poster-assisted PBL model and a control group taught through conventional lecture-based instruction. Data collection was conducted using pretest and posttest instruments consisting of validated multiple-choice and essay questions. The findings revealed a notable improvement in the experimental group’s average posttest score, rising from 66 to 80, while the control group showed an increase from 65 to 75. Statistical analysis indicated that the poster-assisted PBL model had a significant influence on students’ learning outcomes at a significance level of p < 0.05. Furthermore, this learning model not only improved overall achievement but also minimized differences in comprehension among students in the experimental group. The use of poster media as a visual aid proved effective in facilitating students’ understanding of complex biological topics, including human anatomy and the circulatory system. In conclusion, the implementation of innovative instructional models such as poster-assisted PBL enhances students’ conceptual understanding while fostering a more interactive and enjoyable learning environment. Therefore, this approach is recommended for adoption in other educational settings.
