Abstract

Canva as a Science Learning Media to Heat Transfer Material in Elementary School. This article is formulated as the development of learning media in elementary schools, this is motivated by the lack of variety of learning media by utilizing current technological developments. This study uses a development research method with a descriptive approach based on the relevant literature. The development of this learning media is aimed at the subject of Natural Sciences (IPA), especially on the material of heat transfer. The purpose of developing this learning media is so that students learn according to their developmental stages, elementary school students are at the concrete operational stage. This stage is the third stage based on the stage of cognitive development according to Piaget. At this stage the child needs a concrete object or a habit of learning. Using Canva as a learning medium can make it easier for teachers in teaching and learning activities. Learning materials can be animated using the features available in Canva. Thus, students can learn with concrete objects in the form of animations in the science subjects of heat transfer material.

Abstract

The increasing amount of aluminum can waste has encouraged the development of a faster and more efficient processing system. This research focuses on the analysis of kinematic and dynamic performance of a pneumatic-based can pressing machine equipped with a forward–reverse motion mechanism. The study was conducted through machine design, fabrication, assembly, and experimental testing. The developed system used an SC 80 × 175 mm double-acting pneumatic cylinder with a working pressure of 6 bar, operated using a 5/2 solenoid valve. Experimental results showed that the actuator produced a pressing force of 3014.4 N, allowing the machine to perform stable linear movement during the pressing process. Testing on ten aluminum cans showed that the average processing time was reduced from 78 seconds in the manual process to 24 seconds using the pneumatic system. This improvement resulted in a time efficiency increase of 69.23%. These findings indicate that the developed pneumatic can press machine provides better productivity and performance for aluminum waste processing.
