The effect of project based learning (pjbl) based on used cooking oil processing on students’ problem solving ability / Ifta Alifia Zahrani

Abstrak
Problem-solving skills are important skills that students must have to solve complex problems. A complex problem related to the environment is used cooking oil. The material on human influence on the ecosystem taught in grade VII of junior high school is closely related to these problems. The results of observations at SMP Negeri 1 Mojowarno show that learning activities are still one-way students are less active and 75% of students say they have never provided a solution to solve problems. As a solution a Project Based Learning (PjBL) model based on used cooking oil processing was applied which aimed to determine the influence of PjBL on students problem-solving skills. This research uses a pre experimental design in the form of one group pretest-posttest design. The sample of this study is class VII B. The technique in sampling is purposive sampling. The research instruments include teaching modules LKPD pretest-posttest questions and learning implementation sheets. The validity and reliability results of the questions reached a value of 0.61. Based on the results of data analysis a significant difference was obtained with a significance value of 0.000. The N-Gain on the indicator of understanding the problem is 0.75 (high category) devising a plan of 0.9 (high category) and looking back 0.6 (medium category). The indicator of carrying out the plan shows an average score of 89.45 (excellent category). Thus used cooking oil-based PjBL affects students problem-solving skills.
