| dc.description.abstract | The effect of azimuth and pot color on the variation of pot surface and growing media temperature was studied. Four pot colors that including with black, brown, silver and white color were used. The growing media comprised with soil : rice husk : coconut dust at 1:1:1 ratio. From the result of this study, the azimuth and pot color effected the variation of pot surface temperature. The azimuth effected the variation of pot surface temperature at 8.00, 10.00, 14.00, and 16.00. At 8.00 and 10.00, pot surface temperature in east direction was the highest, while at 14.00 and 16.00, pot surface temperature in west direction was the highest. Whereas, pot color effected the variation of pot surface temperature at 8.00, 10.00, and 14.00 with black color was the color that had the highest 33.3, 39.1 and 46.4 C, respectively. On the other hand, the white color was the color that could the highest reduces the pot surface temperature when compared with the temperature of black pot color, which were 4.6, 3.9 and 4.3 C lower than that in a black pot, respectively. Not only, the effect on the variation of pot surface temperature, pot color was also affected on the variation of growing media. Pot color effected the variation of growing media temperature during 8.00 to 18.00. When compare the growing media temperature among the pot color with that in black pot color which was the highest temperature, white color pot was the highest efficiency to reduce the growing media temperature, especially, at 10.00 and 12.00. White pot color could reduce the growing media temperature about 5 C, follow by silver color pot was about 3 C, while the growing media temperature in brown color pot was not difference with that in black color pot | en_US |
