Abstract

Energy sources from non-renewable materials such as petroleum are limited and will continue to decrease. Meanwhile, efforts to find renewable energy sources as reserves require quite expensive costs with a relatively long duration. Therefore, it is necessary to research renewable energy sources, such as corn stovers and coconut shells. This study is generally carried out by making charcoal or carbonization, briquetting, and testing the quality of briquettes. The variables used in this study are the composition of corn cob charcoal and coconut shells. The composition of the mixture used consists of 5 comparative variables, namely sample A = 1: 1, sample B = 1: 2, sample C = 1: 3, sample D = 2: 1, and sample E = 3: 1 with a drying temperature of 100 oC. This study aims to produce biobriquettes from variations in the ratio of good and quality corn cob and coconut shell so that they can be used as environmentally friendly alternative fuels. This study concludes that the optimal mixture variation to produce good quality biobriquettes is found in sample C with a water content of 2.20%, ash content of 3.22%, sulfur content of 0.07%, and a calorific value of 7339 cal/gram because it has a lower optimization compared to other samples and meets the specified standards.

Abstract

Scientific creativity is an important skill in 21st century learning. In practice, many students still have difficulty in developing ideas, exploring, and solving problems innovatively. Various previous studies have developed teaching materials based on Project Based Learning (PjBL) and Augmented Reality (AR) separately. However, none have integrated the two to improve scientific creativity. Based on the results of previous research studies, this study aims to develop student worksheets (LKPD) based on PjBL integrated with AR to improve the scientific creativity of high school students. The research method used is Research & Development (R&D) from ADDIE which consists of five stages, namely analysis, design, development, implementation, and evaluation. Based on the results of previous research studies, both in terms of methods, approaches and use of physics learning media, there is a research gap, the gap between this research and previous research is the integration between AR technology and project-based LKPD. The integration of AR with project-based LKPD simultaneously is something new in this study. This integration will provide a new experience that is more interactive and interesting in the physics learning process. The results of the study showed that the results of the validity test by three experts obtained an average validity score of 3.91 (98%) with a very valid category and a reliability score reaching 95.6% with a reliable category. Thus, this student worksheet is declared valid, practical, and effective in improving the scientific creativity of high school students. The limitation of this study is that this study has only reached the validation stage so that it needs to be implemented in more high schools.
