<![CDATA[There are various factors that become obstacles to the development of renewable energy technology, which are the low knowledge of renewable energy and the low level 21st century skills of people. Therefore, it is very necessary to design a learning that is able to increase knowledge about renewable energy and improve 21st century skills simultaneously. This study aimed to design programs of environmental physics lectures about OWC as a renewable energy source. This research was a developmental research with stages of analysis, design, and development. The products in this study were a test instruments to measure creative thinking skills, OWC converters prototype and project-based lecture programs implementation plans that are oriented towards providing creative thinking skills through a combination of lectures in the classroom, laboratory, and marine environment. All products were validated by 5 experts. In addition beside validation of experts, the creative thinking test instrument was tested on 17 students who had taken environmental physics lectures, while the prototype was tested by a marine engineering laboratory at a university in Bandung. Experts’ validity data were analyzed using content validity ratio, while the test instrument data were calculated for reliability, validity, discrimination and difficulty levels. Based on the results of expert validation, all products are feasible to be implemented. Based on the test results that the prototype developed functions well, while for the test instrument of 10 questions developed only 8 questions were eligible to be used. All of product that produced can be used as a reference and reference for lecturers or teachers who develop learning about renewable energy as well as equip students with creative thinking skills.]]>
