Sasi based on religious is called religious sasi. This research is descriptive research to explain the role of religious sasi culture as one way to preserve the environment. Data were collected by a literature study. The results show that culture sasi can preserve the environment. This is because, in the implementation of sasi, it is prohibited to take and manage the natural products within a certain period. During the duration of the sasi, plants or animals in the sited area are given the opportunity to grow and multiply without any disruption.

This study describes the effectiveness of using Quizizz in fundamental physics online learning activities regarding learning outcomes and student responses. The research was conducted at Musamus University in the odd semester 2020/2021 academic year. This type of research used a mixed method. The subjects in this study were 59 students who took fundamental physics courses. The instruments used in this study were multiple-choice questions, student response questionnaires, and interview guide sheets. This study indicates that the percentage of students’ complete learning outcomes in fundamental physics courses is 79,24%. In addition, 14.3% of students said they strongly agree that Quizizz is effective in learning, and 85.7% say that they agree. The learning outcomes obtained are also supported by interviews, which state that students are pleased and motivated in participating in fundamental physics learning. Because learning basic physics using Quizizz makes them feel that learning is exciting and increases their interest in listening to basic physics learning materials. Thus, it can be concluded that the use of Quizizz in learning Basic Physics in the era of the Covid-19 pandemic has very high effectiveness.

This paper aimed to examine the indigenous culture of the Kanume tribe in the process of making Sagu sep as a medium for Papuan contextual science learning. This research was conducted in the Sota district of the Merauke Regency. The method used is descriptive qualitative research. The data collection technique is done through observation, literature study and in-depth interviews. The data obtained is then represented and interpreted in the concept of the heat exchanger. The results of the study show that there are scientific concepts that exist in the process of making Sagu sep and can be implemented in science learning.
