E-Worksheet is an electronic teaching material designed to guide students in learning activities in a systematic, interactive, and digital technology based manner. The use of E-Worksheet in learning plays an important role in increasing student engagement, especially in practical activities that require independent understanding of concepts and work procedures. This study aims to innovate learning media through the development of E-Worksheet in simple practical activities of making Arabica coffee kombucha. The research method used is research and development with the ADDIE model. The results showed that the developed ELKS had a very good level of feasibility. Media expert validation obtained a percentage of 100% and 90% with feasible criteria, while material expert validation obtained a percentage of 84% and 95% with feasible criteria accompanied by several suggestions for improvement. After improvements were made, the E-Worksheet was implemented in biology lessons on biotechnology and received a 93% response rate from students, categorized as very positive. These results indicate that the developed E-Worksheet is easy to use and effective in supporting the learning process.
