Abstract
The limitation of practicum tools make it difficult for educators to prove science phenomena, especially in cell metabolism material. Therefore, it is necessary to develop a STEM-based practicum tool in order to prove the science phenomenon on the topic of cell metabolism that is abstract. This research aims to develop a practicum tool for cell metabolism learning to determine the results of cellular respiration through fermentation that produces carbon dioxide which has an effect on plant photosynthesis activities. This development model consisted of four stages, namely definition (Define), design (Design), development (Develop), without dissemination (Disseminate). The result of this practicum tool development was that it can prove cell metabolism phenomenon, namely respiration and photosynthesis events which stated that carbon dioxide resulting from anaerobic respiration was very influential in plants photosynthesis process. This could be seen from the result of 5 days observation; first, there was an increase in the plant height. Second, it had stable green leaves. And the last, it had plant leaves that were in fresh condition when receiving carbon dioxide supplies from respiration. This tool is also validated by users, namely science teachers. Based on the results of the responses of 52 science teachers in Lampung Province, they stated that 50% of teachers considered this tool to be in accordance with basic competencies. So from this research, it can be concluded that the development of a STEMbased practicum tool in cell metabolism learning can help to prove cellular respiration phenomenon and photosynthesis. Keywords: Practicum Tool, STEM Approach, Cell Metabolism
