The application of handling organic waste that applies conventional Biotechnology concepts to students in high schools is still very low. Moreover, the concept of Biotechnology innovation is one of the difficult subjects for students. The contextuality of developing learning resources for Biotechnology innovation must be improved through students' understanding of science and hands-on activity. The aim of developing the "Nata De Orange" handout is to improve students' psychomotor skills on Biotechnology concepts. This type of research is Research and Development (R & D) using the Plomp development model with stages a) preliminary research, b) prototyping phase, and c) assessment phase. This handout contains practical activities for making nata from orange juice using Acetobacter xylinum, and opportunities for other materials including household organic waste. The results show that this handout is valid, practical, and effective for improving students' psychomotor skills. The students' response to the use of this handout was very positive, which is a measure of the success of implementing the Nata de Orange handout. Apart from that, this handout can be a reference for science teachers to carry out Biotechnology innovation practicums in making nata.
