The dynamic effect of air temperature and air humidity toward soil temperature in various lands cover at KHDTK Gunung Bromo, Karanganyar - Indonesia

Abstract

Abstract Human activities cause a rise in temperature that causes global warming. Land covers that were originally stand plants into open land will affect the climate of the land. This study aims to determine the dynamics of air temperature & air humidity on soil temperature in various land cover at KHDTK (Kawasan Hutan dengan Tujuan Khusus or Special Forest Area) Gunung Bromo Karanganyar. There are 6 types of land cover used in this study, namely: pine, pine-mahogany, mahogany, mixed, open land, and annual crops. Air & soil temperature were measured using Ellitech RC-5 USB Temperature Data Logger & Digital Thermometer. The results showed that the dynamics of air temperature and humidity were highest in annual crop cover, while the lowest was in mahogany cover. The highest dynamics of soil temperature are found in annual crops and open land, whereas the other cover has similar dynamics. The dynamics of air temperature and humidity are slightly different from soil temperatures. The interaction between air temperature and soil temperature can result in changes in weather and climate, especially in open land.
