This study aimed to test the level of readability and feasibility of science comic, to knowcharacter development through a small test in some schools. The research design was Research & Development, trials were using quasi-experimental pre-test-post-test experimental design. The instruments to measure attitudes were: a questionnaire and observation sheet, a test used to measure comprehension of the material. The results showed that learning science by inquiry-based science comic can improvecharacters and cognitive achievement of primary school students. Results in the form of inquiry-based science comic can be utilized in learning science as a companion teaching materials.

This research aims to improve the creativity of students in developing experiments and the understanding of physics; especially wave; using application of modified free inquiry. This research is conducted in Physics Department, of Unnes. Questionnaire is used to measure creativity, observation sheet to measure the psychomotoric ability, while test sheets to measure the understanding of waves subject matter. Results were analyzed using a Likert scale. To test the effectiveness of modified free inquiry approach in enhancing students‟ creativity and students' understanding of the wave subject matter, normalized gain formula is used. The results shows that by implementing modified free inquiry approaching in the learning process and allowing the students to apply their creativity, will remedy students‟ psychomotoric ability, increasing the number of the experiments type, enhancing students' creativity and cognitive abilities. It is suggested that lecturer gradually and continously provides opportunity for learners to develop their creativity. Kata kunci : modified free inquiry, creativity

In this study, Ce0.85-xLa0.15CaxO2-δ was synthesized using sol-gel combustion method and appliedfor partial oxidation of methane (POM). The physicochemical properties of catalyst were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and thermogravimetric analysis (TGA). Material shows a pure cubical structure and is highly stable up to 850 °C. The performance testing indicated the conversion of CH4 is 65% and selectivity of H2 and CO are 28% and 8%, respectively. The performance indicated the catalyst has a potential to be used for partial oxidation of methane on a larger scale. Copyright © 2021 by Authors, Published by BCREC Group.
