Alef Alizan1), Asis Ramadan2), La Toni3), La Risi4). The development of kakao drying machine design using microwave and solar collectors. Guided by Dr. Eng. Lukas kano M, ST., MT as supervisor and Mr. Prinob Aksar, ST,. MT as Co-Supervisor.final project D-III Mechanical Engineering Vocational Education Program, Halu Oleo University, Kendari 2018.
The aim of making cocoa dring machine used microwave and collectors surya is to make and design cocoa dryer and to know how the cocoa dryer works.
The result on cocoa dryer using combination of microwivw and solar collector for one hour is 11,58% mass reduction. While using the solar collectors for one hours is 4,17% mass reduction.
The cocoa dryer machine componenet consist of microwave, solar collector, lava setting, pushing laver, iron plate, wood beam, triplex, vellk and shaft. From the design that have been done, it is obtain 154cm long, and 70cm high. The dimmension of the sollar collector are 88cm long, 7 cm thick, and 32cm wide, using iron plates 70cm long, 35cm wide, 3mm thick.
