Abstract
Microalgae is a biological material that has an abstract nature, meaning that it cannot be directly observed by the five senses and must use certain tools to see it. The objectives of this study were: 1. Producing biology learning media in the form of modules, 2. Knowing the practicality of the module based on the activities and responses of students, 3. Knowing the effectiveness of using modules based on the achievement of indicators and 4. Knowing the feasibility of the module of microalgae diversity as a learning medium biology to improve the learning outcomes of class X high school students on protist material. This research method uses development research or R D with the development model of Borg and Gall, 1983. The results of the study based on the N-gain value showed that the experimental class got a higher score than the control class and had moderate effectiveness. Based on the validity test conducted by 3 validators, the results stated very valid so that it was suitable for use as a learning medium.Key word: Module, Microalgae, Learning Media

Protists are a kingdom in plant taxonomy
This study aims to; (1) Producing learning media in the form of modules, (2) Knowing the practicality of the module based on the activities and responses of students, (3) Knowing the effectiveness of using modules based on the achievement of indicators and (4) Knowing the feasibility of the microalgae diversity module as a biology learning media to improve student learning outcomes SMA class X on protist material
From the results and discussion that has been described above, the researcher can conclude that the development of the microalgae diversity module as a biology learning medium for class X SMA students has conducted validation tests and direct trials to students
Summary
Protists are a kingdom in plant taxonomy. Protists are divided into 3 groups, namely plant- like protists, animal- like and fungal- like protists. Plant- like protists are referred to as algae or algae. Algae have a macroscopic size (Macroalgae) and a microscopic size (Microalgae). Microalgae are often referred to as phytoplantons and are the largest contributor to all photosynthetic activities that occur on earth. About 70% of phytoplankton absorbs CO2, fills the air atmosphere with O2 and helps the life cycle in the food web in aquatic life (Japa, 2018)
