<![CDATA[This development study aimed to produce and test the feasibility of interactive learning media based on the scratch platform that integrates Mahaffy's Chemistry Tetrahedron approach (macroscopic, microscopic, symbolic, and humanistic) on hydrocarbon material for grade XI high school to strengthen students' systems thinking skills. Using the 4D Thiagarajan development model (define, design, develop, and disseminate), feasibility validation was carried out by chemistry material expert, learning media expert, and chemistry teachers (usability test), while the response test involved 32 grade XI high school students. The research instruments are validation questionnaires and responses with Likert scale 1-5. The results showed that the media obtained very good ratings from teachers and obtained good categories of student responses. The Media is stated to be very suitable for use in Chemistry learning and potentially optimally supports the strengthening of systems thinking through the integration of interactive and contextual chemical representations. The media was declared very suitable for use in chemistry learning and has optimal potential to support the strengthening of systems thinking through the integration of interactive and contextual chemical representations.]]>
