The Special Region of Yogyakarta has a high level of plant diversity and needs to be optimized as a learning resource. The purpose of this study was to analyze the rate of photosynthesis and levels of lead (Pb) in red shoots (Syzygium oleana) as a learning resource in biology material about metabolism in high school class XII. Biology requires a reference to teach metabolism material based on the influence of internal and external factors. This research was conducted in the area of Jalan Cik Di Tiro Yogyakarta. The research design uses exploration. The population in this study were three Syzygium oleana plants in the Cik Di Tiro street area, Yogyakarta. The population was taken using the target population and determined 6 leaves as a sample using random sampling technique. Exploration results obtained differences in the rate of photosynthesis and lead content. The rate of photosynthesis and lead absorption in red leaves of Syzygium oleana is lower than that of green leaves because it is influenced by internal and external factors. This study can reveal the potential for plant diversity in the Special Region of Yogyakarta and analyze the potential for learning resources. The process and results of this study have the potential to be a source of learning biology for high school class XII on metabolism material which refers to the 2013 curriculum. © 2023 Author(s).
