Abstract: The inversion algorithm of a fuzzy neural network is a process of computing inputs that produce a given target when fed into the neural network. The inversion algorithm of fuzzy neural networks is based on the gradient descent method, in which we obtain a new estimate inverse of T, and adjust the total inputs in the input layer, then iteratively decrease the error between its output and the target. First, we present a framework of learning algorithms of fuzzified neural networks and introduce the idea of fuzzy number. Next, we derive the inversion algorithm of fuzzified neural networks by applying the adjusting scheme for fuzzy variables to total inputs in the input layer. Finally, we give an example based on if-then rule and apply the proposed method on it.

Abstract: Trichogrammatoidea armigera, a parasitoid that parasitizes Helicoverpa armigera eggs, is a major pest of several crops in North Sulawesi. They can be used as biological agents to control unwanted crop pests. We have studied the parasitization level of T. armigera by using Corcyra cephalonica as the alternate host. We investigated the parasitization levels as functions of the host egg age and the age of parasitoid imagoes that were bred in corn, rice, peanuts and mung beans fine grains media. Experiments on the suitability of C. cephalonica host eggs were carried out in a completely randomized factorial design with the factors of the age of host eggs and feeding media. The experiments on the effect of age of host parasitoid imago were conducted in completely randomized design. The results showed that the older the age of the host eggs, the lower the parasitization levels. And for the feeding media, the highest level of parasitization was found in mung beans with 38.07% of parasitization level, and lowest was in rice at 25.18%. We also found that the size of the parasitoid imagoes in mung beans was relatively bigger than those in corn, peanuts, and the smallest one was in rice. The age of parasitoid imago without host in mung beans could reach 96 hours and were still capable of parasitizing C. cephalonica eggs at a level of 16.5%, in peanut could reach 72 hours with a parasitization level of 12.50%, in corn could reach 48 hours at a level of 22.50% and in the rice only reached 24 hours at a level of 19.50%. Young parasitoids had a higher parasitization level than the older ones after C. cephalonica host was introduced. 24 hours age of T. armigera imagoes in mung beans had a relatively high parasitization level after the introduction of C. cephalonica eggs, as well as 8 hours in corn and rice, and 4 hours in peanuts.

Abstract: The purpose of this study was to investigate the impact of empowerment on organizational commitment and job satisfaction of employees of the national electricity company (PLN) in the Province of South Sulawesi. This study was explanatory research study which employed survey method. The population number for this study was 836 people. The study sample (n = 270) consisted of middle managers, basic managers, the basic supervisor and the upper supervisor. Samples were spread over five regional offices of the national electricity company (PLN) in the province of South Sulawesi. In Makassar area, the steam power plant (CPP) is in Tello. Area distribution and load settings (AP2B)werethroughoutSouth Sulawesi and regulatory area distribution (APD). The instruments for the data collections were interview and questionnaires. The data was analyzed by using quantitative research analysis through a generalized structured component analysis (GSCA). The study found a significant effect of the empowerment on the organizational commitment. Despite the empowerment had no significant effect on job satisfaction directly, but it was found that the indirect significant effect between empowerment on the job satisfaction through the intervening variable of organizational commitment; organizational commitment had a significant effect on job satisfaction.
