Science learning based on local wisdom is increasingly gaining attention in the context of learning, especially ethnoscience approach that connects science with traditional knowledge of the local wisdom. This study aims to make science learning more relevant and contextual for students by connecting scientific concepts with local wisdom in the community. The research method used literature review study by collecting reference sources from Google Scholar. Literature studies that examine various studies related to the application of science learning based on local wisdom to use local wisdom in science education in schools. The data analysis technique used in this literature study research is content analysis that contains science process skill and critical thinking skills. The journals that are in accordance with the topic consist of 10 articles. The results of this study indicate that the application of ethnoscience through local wisdom can improve students' understanding of scientific concepts, strengthen their involvement in the learning process, can improve students' science process skills, such as observing, experimenting, analysing, and concluding data, and encouraging the development of critical thinking skills.

The determination of customary land rights for indigenous communities in border areas grows increasingly complex when assessing individual claims within the framework of collective rights. This study aims to formulate a legal protection model for the customary land rights of indigenous communities along the Indonesia-Papua New Guinea border. To formulate this model, the research will comparatively analyze the conceptual frameworks governing customary rights across three existing border areas, namely in Jayapura Regency, Boven Digoel Regency, and Merauke Regency. The research method used is normative empirical, with data collection techniques through observation, documentation, and interviews. The data analysis technique used in this legal research is qualitative-descriptive data analysis. Critical Review of previous studies reveals a significant research gap regarding the protections for customary law communities, especially customary land rights in the Papua border area. This study identifies the absence of a comprehensive scholarly examination regarding the protection and control of customary land rights in the border area between Indonesia and Papua New Guinea, especially in Merauke Regency, Boven Digoel Regency, and Jayapura Regency.
