The purpose of this research is to teach the deaf community to make dishwashing liquid soap to introduce applied chemical technology. Learning to make dishwashing liquid for the deaf community is not only improving their soft skills but also necessary to provide knowledge and understanding of the theory of applied chemistry. This research used pre-experimental one group pretest-posttest design method with eight subjects from the deaf community. Several steps were taken including providing a pretest, watching two videos that duration of 1 minute 26 seconds and 9 minutes 57 seconds using sign language, doing the posttest, and comparing the pretest and posttest. The results showed that deaf community understood that soap is a part of applied chemical technology. They could follow the steps learned and could make dishwashing liquid. The issue of learning for the deaf is not dependent on the simple or difficult materials given. The hypothesis that chemistry learning is difficult for deaf people to understand is likely to begin setback if the strategy can be modified to be as efficient as possible. Applied chemistry technology can be taught to deaf communities through video media using sign language adapted to the signs used on a daily basis. © School of Engineering, Taylor's University.
