<![CDATA[This research aims to develop interactive multimedia based on Project Based Learning (PjBL) for the material of Composing Simple Algorithms (Scratch) in Informatics subject for Grade VIII students at SMPS IT Dar El Iman Padang. The 4D development model (Define, Design, Develop, Disseminate) by Thiagarajan et al. (1974) was employed. The Define stage identified that learning still relied entirely on direct demonstration and conventional job sheets, with no interactive media available for independent study, and high rates of students failing to meet learning mastery. The Design stage produced a web-based product called 'Scratch Project' integrating PjBL syntax into structured multimedia content. The Develop stage yielded a product validated by two media experts (average score 98.5%) and one content expert (95.79%), both categorized as 'Very Valid'. Practicality testing involving 23 Grade VIII students resulted in an average score of 89%, categorized as 'Very Practical'. The Disseminate stage was conducted on a limited scale by distributing the product link directly to students and teachers. This study concludes that the PjBL-based interactive multimedia is valid and practical for use in Informatics learning.]]>
