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

Access to clean water in Indonesia's remote coastal areas requires a self-sufficient and sustainable desalination solution. This study aims to optimize a prototype of a non-invasive solar desalination system by integrating Photovoltaic-Thermoelectric (PV-TE) hybrid technology for off-grid clean water production. A pilot-scale unit was developed from a basic passive solar distillation prototype through the addition of photovoltaic panels and thermoelectric modules that double as waste heat recoverers and active condenser coolers. Test results show significant performance improvements, with conductivity removal efficiency reaching 99.83% with ultra-pure water quality (80 µS/cm). Water productivity increased exponentially by 1148%, from 0.50 L/day.m² in the basic prototype to 6.24 L/day.m² in the hybrid system, with a system energy conversion efficiency reaching 29.05%. These findings confirm that the strategic integration of PV-TE components not only overcomes productivity limitations in passive solar desalination but also offers an autonomous desalination solution with low environmental impact. This research contributes to the development of self-sufficient water infrastructure that can be replicated in coastal communities with abundant solar intensity.
