The preparation of scientific literacy tests is very important knowledge for teachers in 21st-century learning. Therefore, teachers must have knowledge about the preparation of scientific literacy tests for students. This service research aims to increase knowledge about ways to arrange a scientific literacy test through the teachers of the Bulustalan State Elementary School. Participation in training activities through this service are all teachers at the Bulustalan State Elementary School. The method used in this service research is to use the lecture, practice, and assignment methods. This service activity has a good impact, namely providing insight to teachers about literacy test instruments to face the 21st century and increasing teacher competence related to skills in preparing scientific literacy test instruments that can be integrated into the form of multiple-choice tests and essay tests.

The foodstuff course is one of the subjects that is closely related to the context of daily life. The learning model that has been applied by lecturers has not been able to encourage students to use science process skills optimally and produce real work. The teaching materials used also have not trained students' skills and independence in solving problems of daily life. Borax is a prohibited additive in foodstuffs. This study aims to develop borax indicators from natural substances and develop project-based student worksheets to improve science process skills. The development of natural indicators of borax was carried out using the true experimental design method. Extracts of natural indicators were tested for color change in a solution of pH 5, 7, 12 and on positive and negative borax food samples. The development of student worksheets is carried out using a 4D (defining, designing, developing, and disseminating), model and is only limited to the stage through expert review. LKM that has been developed are validated by experts. The data obtained were then analyzed descriptively. The results showed that (a) extracts from secang wood and turmeric could be used as natural indicators of borax and (b) expert assessment of aspects of student worksheets obtained results in the high and very high validity ranges. The results of the development of natural indicators of borax can be used in the development of teaching materials. The developed student worksheets are suitable for limited testing

Abstrak. Hydrocarbon material is a material that examines abstract concepts related to atoms and structures. However, Generation Z has characteristics that rely heavily on digital technology. Characteristics of materials and students who are different, of course, will hinder achieving the objectives of learning hydrocarbons. Chemistry learning will be effective if hydrocarbon material is integrated through the development of vlog media content that raises local wisdom or ethno-STEM (science, technology, engineering, and mathematics). So, will provide in-depth and comprehensive understanding of students into scientific knowledge. The research aims to produce an ethno-STEM integrated vlog media and its effect on the provision of conservation characters and chemistry literacy of students. The development of ethno-STEM integrated vlog media in research uses the 4D method, namely definition, design, development, and dissemination aimed at class XI science students who are studying hydrocarbon material at SMA Negeri 3 Batam. The data was obtained through observation and structured interviews with 1 chemistry teacher and 17 students. The results of the validity of the material (0,87), media (0,77), teacher practicality (0,79), student responses on the small-scale (0,79), large-scale (0,83). The vlog media (0,91), conservation character (0,63) and chemistry literacy correlation coefficient (0,54). The reliability of the question (0,58), discriminating power (0,22) and difficulty level of the item pre-test (0,76) and post test (0,93). So, it can be concluded that the vlog media developed is valid, practical, and effective as local wisdom content to equip conservation characters and chemistry literacy.
