Abstrak

This study aims to examine heat transfer and mass transfer through a mathematical approach to the para system potato seed storage device with forced airflow. Observation parameters include: material temperature, air temperature and air humidity. Based on the results of observations for 63 days, the increase in air humidity on each shelf varies between, 0,306 – 0,636 watter vapor/kg of air, with a decrease in moisture content of 0,05% – 0,49%. The airflow forcibly reached a speed, 0,73 m/sec – 2,16 m/sec. Based on the analysis of the mass balance, relative air humidity, 75,17% – 80,85%. Whereas in the balance of heat energy lost to the environment with the mathematical model approach the empirical equation QL = Qp - QӨ - QU, dissipating heat reaches, 798,794 watt / sec – 275,0968 watt / det and able to provide good oxygen, with temperatures ranging between, 30,49ºC – 30,02ºC. Based on the phenomenon of respiration heat, the results of mathematical equation calculations, show that the shelf
height affects the heat transfer experienced by potato tubers. Seen at the height of the 3rd rack, when measured from the base of the rack has a height of 75cm, showing heat, 529,842 watt with a relatively variable heat, 19,7 watt/det – (-5,3 watt/sec). While the 5th rack, with a shelf height of 125cm, shows heat, 523,883 watt with a relatively variable heat range, 16,8 watt/det – (-4,8 watts/sec) on the rack-5.
