Abstract
The purpose of this study was to identify direct and indirect effect from hemoglobin level and working memory to learning outcome of cell subject matter. The samples of this research were 52 male students. This research was conducted at SMAN 22 Jakarta in July-August 2018. The level of hemoglobin was measured by cyanmethemoglobin method from HemoCue device, working memory was measured by questionnaire, and learning outcome by achievement test. Data was analysis with path analysis. The results showed that there was direct effect from hemoglobin level to working memory, direct effect from hemoglobin levels to learning outcome, and direct effect from working memory to learning outcome. There was indirect effect from hemoglobin levels to learning outcome through working memory. The effects were highly significant. It can be concluded there were direct effect from hemoglobin level and working memory to learning outcome.
