Simulasi Pengendalian Kadar Air Medium Tumbuh Jamur dengan Logika Fuzzy

Abstract

Research on temperature control for mushroom has been done using fuzzy logics. The side effect of reducing temperature is the decrease in relative humidity inside the growing room, so that the bag log (mushroom growing media) becomes drier and reduces water content below optimum value. The water content of the mushroom growing media should be maintained at the optimum value of between. 65 and 70 percent. The objective of this research is to know the variation of water content. , Measurement of water content was done at two conditions. First, the bag log was 1 submerged into water and second, the bag log was not. The measurement was done I at temperature of 1 7 ' ~ . The water content was raised from 34.9 percent to 65.4 percent in six hours. The time needed for lowering water content from 85 % to 65 % was 12 hours. The data of resulted from raising and lowering of water content were used for designing simulation for controlling water content using Fuzzy Logic Controller. The fluctuation of water content was between 65 and 68 percent with error values of between 1.6 and 2.6 percent. The variation of the water content resulted was still within the optimum requirement.
