Temperature and soil control design with fuzzy method in greenhouse for cabe seeding

Abstract

The ideal soil temperature and humidity in red chili pepper seedling are very important in the growth of the plant. The cultivation of red chili plants in greenhouses is very good because the environment in greenhouses can be manipulated according to the needs of that plants. The ideal temperature for red chili breeding is 25oC to 27oC, for soil moisture drainage and temperature must be maintained during growth. Red pepper plants can grow well in moisture 50% to 70%, irregular soil moisture can cause rooting disease and root decay in plants. Cultivation of plants in greenhouses can maintain the nursery process because the plants can be cultivated in accordance with the Operational Procedure Standards (SOP). Generally, the farmers in the breeding of red pepper are done in a traditional way. In the process of temperature control and soil moisture through a fuzzy method, it makes the system can work automatically. Thus, it can facilitate the work of farmers in seeding plants from uncertain outside environmental conditions. In the measurements that have been done can be taken conclusion which is percentage error mean temperature from set-point which has been set at the time in the morning equal to 2,48%, at noon around 9,79% and at night we got 1,93%. Then each addition of 1second watering, soil humidity rise up to 0.067%.
