Abstract

The purpose of this study was to develop a problem-based learning model for fourth-grade elementary school students in order to improve their communication skills. This is a research and development (R&D) project using a combined approach (mixed methods), specifically Borg and Gall research combined with ADDIE design development. The type of research that was conducted was True Experimental research with a post-test only control group design. Data collection techniques included tests and non-tests. The effectiveness of the problem-based learning model was determined through data analysis using the t-test. The results indicated that t arithmetic > t table (9.84 > 2.012) was rejected at a 5% significance level, while Ha was accepted and supported by observations of student communication skills in six lessons, which revealed an average of 80.07 percent of 24 students in the very good category. As a result, it can be concluded that the design model for problem-based learning is effective at improving communication skills.

Abstract

This study aims to analyze the strengthening of students’ ecological citizenship through the waste bank program at SMA Negeri 9 Bandar Lampung as a medium for ecological character education that fosters discipline, social responsibility, and environmental awareness. The research uses a qualitative approach with a case study method involving the principal, program supervisors, waste bank ambassadors, active students, and the Sahabat Gajah community. Data were collected through in-depth interviews, observation, and documentation and analyzed through data reduction, data display, and conclusion drawing. The results show that the strengthening of ecological citizenship occurs through active participation in waste bank program activities such as socialization, training, waste collection and sorting, ecobrick production, and waste management through a savings system in collaboration with Bank Mandiri. These activities habituate students to be disciplined, comply with procedures, and promote social responsibility and environmental awareness. The waste bank program provides a positive impact in shaping environmental care, responsibility, and cooperation, although there are challenges such as uneven participation and limited understanding of environmental preservation.
