Environmental characteristics in coastal areas are receiving less attention, especially for science education development. However, it provides relevant learning objectives, such as the presence of seagrass and marine aquaculture. This study aimed to assess the contribution of student worksheets (synthesis of seagrass ecology and marine aquaculture values) in increasing students' scientific literacy. The method used is quasi experiment with pre-post-test design, followed up by the learning observation to strengthen the quantitative data. Data were analysed on using simple statistical analysis. The results showed that all students knew seagrass and marine aquaculture. Furthermore, the post-test results show that the average value of the control students is lower than the average grade of the experimental class. Meanwhile, student from the experimental classroom shows more innovative in completing project-based learning tasks. It is relevant to students who understand seagrass and marine culture, where they interact after returning from school. This research concludes that the of student worksheets material based on local indigenous value played role in enhancing students' scientific literacy. Besides, the short essay on science and its values can replace the role of science teaching material that still rarely provided by teachers/schools.
