Biology learning, particularly the abstract topic of the Excretory System, demands high visualization, which is often lacking in conventional media. This Research and Development (R&D) study, utilizing the ADDIE model and focusing on the validation stage, aimed to develop and assess the academic feasibility of a digital learning medium based on Lecture Maker software. Following a thorough analysis of curriculum objectives and student needs, the product was designed to integrate text, images, animations, and videos to present complex physiological concepts. Product validity was rigorously assessed by both subject matter and media experts, yielding an average total score of 4.15, which categorizes the medium as Valid. Detailed results showed high scores for design/structure (4.19) and language (4.50), while the content/substance aspect received the lowest rating (Sufficiently Valid, 3.76), indicating specific areas for revision concerning the simplification of scientific language and enhanced visualization. In conclusion, the developed Lecture Maker-based medium is declared academically feasible and valid, fulfilling the criteria for quality educational media and is ready to be utilized in the subsequent implementation stage to assess its practical effectiveness on student learning outcomes.

The study successfully developed a Lecture Maker-based learning medium for the excretory system, deemed valid after expert assessment.The medium met validity criteria overall, with design and language receiving valid ratings, though content requires minor revisions.This demonstrates the effectiveness of a structured R&D approach, including the ADDIE model, in producing quality learning media.

Further research should investigate the practical effectiveness of the developed Lecture Maker-based medium in real classroom settings to assess its impact on student learning outcomes. Additionally, studies could explore the adaptation of this medium for different learning styles and student needs, potentially incorporating personalized learning features. Finally, research could focus on expanding the development of similar Lecture Maker-based media for other complex biology topics, contributing to a more comprehensive suite of validated digital learning resources for biology education. These investigations will not only refine the current medium but also provide valuable insights into the broader application of technology-enhanced learning in biology, ultimately improving student understanding and engagement with challenging scientific concepts.
