PENENTUAN WAKTU PENGGUNAAN WATER CHILLER PADA TANAMAN KENTANG BERDASARKAN SEBARAN SUHU DAERAH PERAKARAN
Abstrak: The difference of
lowland and upland ambient temperature, around 7 C, is an obstacle to plant
highland crop in the lowlands. Therefore, many methods were applied to adjust
this condition, for example the application of water chiller to decrease the
temperature of nutrient solution. However, until now the application of water
chiller has not been optimum, because generally water chiller work all day for
24 hours, without considering the actual microenvironment of the plant. This
study aims to optimize the application of water chiller for potato crops that
usually plant in lowland, by determining the time of use of water chiller based
on the distribution temperature of root zone that was simulated by
Computational Fluid Dynamic (CFD). This research begins with making a CFD
simulation by Solidworks 2011 software, consisting of preprocessing, solving,
and post-processing stages. The results show that water chiller for potato
plants only needs to be activated from 08.00 to 17.00 o'clock, because only
around that time the temperature of the root area exceeds the optimum
temperature for the potato crop growth.
