This study aims to determine the improvement of learning outcomes on theme 8 Lingkungan Sahabat Kita through a problem-based learning model based on audio-visual media for class V at SDN 1 Tutup. This research is a classroom action research developed by Kemmis and Mc Taggart. The subjects of this study were students of class V even semester in the academic year 2020/2021 with total of 30 students. This study consisted of three cycles with two meetings in each cycle. Data collection techniques in this study used observation, tests, and documentation. The results showed that the application of Problem Based Learning (PBL) learning model on the theme 8 Lingkungan Sahabat Kita could improve the learning outcomes of class V SDN 1 Tutup. This can be seen from the increase in student learning outcomes in each cycle. In the first cycle, the average value of the students' knowledge learning outcomes was 68.75, the second cycle increased to 71.77 and the third cycle increased to 79.27. Psychomotor learning outcomes of students in the first cycle of 71.30 increased in the second cycle to 73.58 and also increased in the third cycle to 75.86.Keywords: problem based learning; learning outcomeAbstrak: Penelitian ini bertujuan mengetahui peningkatan hasil belajar pada tema 8 Lingkungan Sahabat Kita melalui model pembelajaran problem based learning berbasis media audio visual kelas V di SDN 1 Tutup.

The environmental crisis is getting worse these days, resulting in a debate about the paradigm of natural resource management to emerge. The aspiration for sustainable natural resource management is getting stronger from civil society movements and the wider community. The purpose of this research is to describe eco-populist thoughts and actions in peatland management and to strengthen the position of the eco-populist paradigm as the right paradigm in peatland management. This research is qualitative research with a case study approach, namely research conducted intensively, in detail and in-depth on a problem that is the object of research. The results of this study contribute to a fundamental-philosophical error in peatland management. Promote a sustainable perspective on peatland management based on local knowledge, reinforced by paradigmatic studies. A perspective that harmonizes ecological and human (community) interests. Not a viewpoint that ignores certain subsystems. In natural resource politics, there are at least three paradigms. First, the conservationist paradigm, which places natural resources solely for conservation. Second, the developmentalistic paradigm, which views natural resources as development assets. Third, the eco-populistic paradigm, which is a holistic perspective that humans, flora and fauna and their environment are one ecosystem. The loss of one element shakes the joints of the other component. Peat management is one of the world's highlights today. The critical issue is that climate change is linked to the destruction of peat due to unsustainable management. Until now, peatland management is still dominant with a developmentalism cum conservationist paradigm. So it is necessary to strengthen paradigmatic in sustainable peatland management.
