This study aims to determine the achievement and improvement of the abilities gained by students with project-based learning models (PjBL). The method used in this study is a pre-experimental method with research design one group pretest-posttest. This study uses one class. The population of this study was all students of class VII A with total of 36 students. The study instrument used was a test of creative thinking skills and non-test abilities consisting creativity, presentation and percentage, and the implementation of the learning model. The result of this study obtained by paired t-test showed that there is a possibility of using the PjBL model to the creative thinking skills with a significance value of 0.000. These results indicate that PjBL effects creative thinking skills. In addition, the improvement of creativity based on the test of creative thinking skills has a value of 0.56 (56%) with medium category, the average value of innovative products is 85.71% with outstanding classes, and the performance & percentage are 73 with good classes.
This article aims to explore a startegi in the form of the implementation of organic waste management to create sustainable skills and mindsets. The method used in this study is the weak method of experimentation. Instruments used in research in the form of instruments about 15 questions are tested before and after learning. The sample used in this study as many as 32 students in one of the junior high schools in Pandeglang. The results showed an increase between the pretest and postest student results with a significance level of 0.00 which showed that there was an influence between sustainable development education integrated organic waste management and improved sustainability literacy. While the acquisition of N-Gain score of 46.87% with low category, 46.87% medium category and 6.25% in the high category. N-Gain scores show less than optimal results, because some students get low N-Gain grades. Thus, this research can be concluded to be able to increase the sustainability literacy of students with low categories. Therefore, it needs to be re-studied for further research. The results of this study are also useful for anyone who wants to learn about sustainable lifestyles, especially in organic waste management.
