Abstract

ABSTRACTTissue culture is a technique widely used for propagation and improvement of crop quality. One way of plant propagation can be done with in vitro techniques. The purpose of the study was to determine the combinations and concentrations of NAA and BAP are appropriate for plant propagation patchouli. Dependent variable is the time of initiation of callus and shoots, callus texture, color callus, shoot number, and the number of roots patchouli. Independent variable is the concentration of growth regulators NAA and BAP. The method in this study is the experimental method. Data were analyzed by two-way Anova test followed by Duncan’s Multiple Range Test (DMRT). The results showed the stem explants concentrations of NAA and BAP best to induce callus is without NAA and BAP (control), 0.1 ppm NAA without BAP, NAA + BAP 0.5 ppm 0, while the leaf explants is there a 0.1 ppm NAA without BAP, NAA 0.1 ppm BAP + 0.5 ppm, 0.5 ppm BAP without NAA and NAA + BAP 0:01 ppm 1 ppm. Highest number of shoots obtained at a concentration of 0 ppm NAA concentration and NAA and 0.01 for leaf explants at a concentration of 0:01 ppm NAA + BAP 1 ppm and 0 ppm NAA + BAP 0.5 ppm for stem explants. Highest number of roots was found in 0:01 ppm for NAA concentration and leaf explants at a concentration of 0.1 ppm NAA + BAP and NAA 00:01 0 ppm ppm + 0.5 ppm BAP stem explants. Results of statistical analysis showed that there were significant differences of NAA and BAP concentrations on plant propagation patchouli (Pogostemon cablin Benth).

Abstract

This research was motivated by the low learning outcomes of students in science subjects at SMPN 4 Pariaman. For this reason, in the teaching process it is necessary to use appropriate learning models. One learning model that can be used is the Project Based Learning (PjBL) model. The aim of the research is to determine the effect of implementing the PjBL learning model on the learning outcomes of class VII students at SMPN 4 Pariaman in the subjects of Ecology and Indonesian Biodiversity. This research uses a quasi-experimental type of research with a non-equivalent control group design. The research population was class VII students of SMPN 4 Pariaman TP.2023/2024, with a purposive sampling technique. Class VII.1 was chosen as the experimental class and class VII.2 as the control class. The experimental class uses the PjBL model, while the control class uses the conventional model. The instruments used were observation sheets on the implementation of the PjBL model and objective test questions adapted to the KKTP on Indonesian Ecology and Biodiversity material. The data obtained was analyzed and prerequisite tests and hypothesis tests were carried out. The results of the posttest value hypothesis test using the t test show tcount of 8.13 and ttable 2.00. The data shows tcount > ttable so that H1 is accepted, meaning that there is a significant difference between the average posttest scores of experimental class and control class students after being given different treatment. It can be concluded that providing treatment by applying the PjBL model has an influence on student learning outcomes in Indonesian Ecology and Biodiversity Material for class VII SMPN 4 Pariaman.
