Chemistry learning is one of the processes to provide knowledge and skills about chemistry contained in nature. Understanding the concept of science-related literacy can be improved by the application of learning methods, because with a precise understanding of the concept it can provide ease, increase interest, and student motivation. In this research, it will be developed learning device of guided discovery learning model of hydrocarbon subjects in State Senior High School students. In this study, it will be described the validity, practicality, and effectiveness of learning devices based on guided discovery learning. This study was conducted using hydrocarbon learning materials with basic competence on alkanes, alkene and alkyne on chemistry subjects, with test subjects being SMA 18 students. Based on the result of this research, it can be seen that the proposed learning model for hydrocarbon material on the basic competence of alkanes, alkene, and the alkyne can be declared valid by both validator-based and practical results as seen from the results of the Lesson Plan, which is highly categorized by the observer, and effective by the improvement of mastery. Keywords— Literacy Science, Guided Discovery Learning, Learning Devices, Learning Outcomes.
