ost fishermen in Gresik, East Java, Indonesia used open air bamboo wicker as a conventional solar fish dryer. However, the dryer has weakness such as need long time to dry and cleanliness issue. The condition raises the idea of designing and manufacturing solar cabinet dryer to improve efficiency and overcome the weaknesses in a conventional fish dryer. The solar cabinet dryer contains 3 kg fish and designed in 3 shelf collectors which are equipped with mirror to maximize solar radiation. The fish dried to below 40% of moisture content based on Indonesian National Standard. Dryer performance is measured from drying rate and efficiency. It found that the drying rate per hour was 18.93%, 20.81%, 20.92% mass/hour for 30o, 45o and 60o mirror angle respectively. Highest efficiency performance of solar cabinet dryer was 34.94%. In cleanliness issue showed a decrease of 25.1 x 106 bacteria colonies/gr on conventional drying to 19.5x106 bacteria colonies/gr on designed solar fish dryer.

Index Terms--Cabinet, drying rate, efficiency, fish, solar dryer
