Abstract

Farmers in Bali have not been able to produce good seeds due to failures at the storage stage and are still dependent on potato seeds from the G2-G4 group imported from outside. The aim of this study was to determine the dynamics of air temperature and humidity (RH) during the storage of potato seeds and the physical changes of potato seed tubers after storage. Parameters measured included temperature and humidity during storage of potatoes, analysis of mass and energy balances, calculation of respiration heat, heat for increasing the temperature of potatoes, heat for water evaporation, and heat lost to the environment with a simple mathematical model approach. The results showed that temperature tends to form a quadratic polynomial pattern, while RH tends to form a linear pattern. The temperature of the potato storage room was in the range of 29.50 ºC - 29.09 ºC and the RH was in the range of 73.00% - 81.80%. Respiration heat value varies between 470.26 - 491.30 Watts. The heat generated from the respiration process is 72 -143 watts, the heat to raise the temperature of the potato tubers around the potatoes is 2.02 Watts; 1.81 Watts; 3.80 Watts; 2.60 Watts; 10.70 Watts; and 15.20 Watts. The heat lost to the environment forms a linear pattern. Para-Para is capable of creating conditions for the storage and supply of oxygen that, for physical change, are almost non-existent.
