Hence, they need dryer tool to solve their problems. Therefore, research is done to stake out prototype of the dryer tool based on hybrid by using electric energy and sun's rays, which is called Smart Cacao Dryer. This research is supposed to create dryer tool which is able to use without considering weather and climate change but it creates cacao seeds which is appropriate to Indonesia national standard. Methods used are designing, assembling, examining, socializing, mentoring, and evaluating the tool. Cacao seeds result dried by using smart cacao dryer showed the same result as Indonesia National standard.
