Abstract

The increasing demand for paper has significantly impacted the environment due to the heavy reliance on wood as a primary raw material. This study investigates the feasibility of using durian (Durio zibethinus) peels and corn (Zea mays) stalks as alternative raw materials for paper production, focusing on their physical characteristics. The paper pulp was prepared using the soda pulping method with NaOH. Various ratios of durian peels and corn stalks were mixed: 1:0 (A), 0:1 (B), 1:1 (C), 2:1 (D), and 1:2 (E). Results indicated that type D produced the thickest paper, while type A produced the thinnest. The highest grammage was observed in type E, and the lowest in type D. Type C showed the highest absorbency. The tensile and tear indexes were highest in type D and lowest in type C. Type A had the highest mass density, whereas type D had the lowest. The findings suggest that a combination of durian peel and corn stalks exhibits diverse physical properties, indicating their potential use as an alternative to conventional wood-based paper. This approach could reduce the dependency on wood and contribute to environmental conservation.

Abstract

Physics is a branch of science that discusses natural phenomena. Physics learning process is expected to facilitate students to observe the phenomenon directly, but not all phenomena can be observed directly. One of them is static electricity subject material. So, learning media is needed that can channel information to students. Teachers can create various learning media with dynamic representations such as Augmented Reality. This study aims to determine the feasibility of Augmented Reality based learning media on static electricity material developed. This research is a type of R & D (Research and Development) research with the 4D model (Define, Design, Development, and Disseminate). The media feasibility test is determined through validation by 4 validators, namely 2 media experts and 2 material experts. The results of the feasibility test in terms of media with indicators of graphics and language got a percentage of 81% with very feasible criteria and in terms of material with content, presentation, and contextual indicators of 83% with very feasible criteria. Thus the development of Augmented Reality-based learning media on static electricity material is very feasible to use in supporting physics learning.
