ANALISA PENGERING IKAN AIR TAWAR DENGAN MENGGUNAKAN SISTEM HYBRID KOLEKTOR SURYA TIPE RAK DENGAN SOLAR CELL

Abstract

In South Kalimantan precisely in regency of Hulu Sungai Selatan Amuntai, it
is one of the dry fish manufacturing of regency in South Kalimantan. The process of
drying fish is still doing by traditionally where the fish are drying by utilizing the
energy of the sun directy. The main problem that arise in unfavorable of drying
process is a decrease in quality such as a large distribution of water content, the
damage that caused by fungus or biochemical change that unwanted. If the
distribution of heat and air is uneven or uniform, the drying rate of the material will
also be uneven.
The method of research was conducted by several stage, first prepare the test
equipment, namely fish dryer that has been designed in such a way based on the
result of calculation and then put in the test location and the collector is directed to
the sun and for testing sample by using freshwater fish, sepat fish and haruan fish
obtained from the result of local resident, as a measure of temperature in the drying
chamber is using a thermometer to know the temperature in the fish dryer.
Based on the data of analysis and discussion, can be taken the conclusion
about fish dryer that is the distribution of the drying rate in the each rack have
variation according to the temperature of the each rack. The result of drying the sepat
fish for 7 hours by using solar power dryer were able to reduce the weight of sepat
fish from 500 g to 200 g and the wet weight of haruan fish from 500 g to 200 g. The
total efficiency of solar power dryer is 79.768%
