      Abstract: The hood is an alternative to overcome the high intensity of sunlight. In this study the type of containment material treatment can be divided into 3 types of containment material, namely the type of plastic lid material, paranet and combination. For microclimate measurements, a temperature and humidity meter and a light meter are used. Microclimate measurements were carried out at 12.00 WITA, on cayenne pepper from 7 days to 35 HTS. Micro climate data analysis is done by interpolation to obtain the profile contour lines. The results of the study showed that there were different shapes and distribution of different micro-climate profile contours, especially in light intensity. At air temperature and air humidity can not obtain contour lines, because the results of the data from the research conducted are not much different. Plant growth rates in each treatment showed different productivity. In this type of paranet lid material shows better results compared to the type of plastic hood and combination material. In this type of paranet lid material produces an average dry weight of 247.9 grams. Keywords: hood type material, cayenne pepper plant, microclimate.
