Pengelolaan Kesiapan Belajar Anak Masuk Sekolah Dasar

Readiness of children to enter school is something that is very important that every child must have because the readiness to attend school is the first capital to follow the process of learning activities in school. The greater the readiness of the child, the greater the child has the ability to follow the poses of learning activities at school. Conversely, the smaller the readiness of children's learning, the smaller the children have the ability to follow the poses of learning activities at school. The problem is that many children do not have readiness to learn well because parents have not manage the readiness to learn children enter school well. In the readiness of learning children enter primary school can not come suddenly in the child because everything must be well prepared, including that of elementary school age, cognitive, affective, and psychomotor ability of children and others needed by children. The role of parents and teachers in "pre-school" institutions / education at an early age is very important in managing preparing children for elementary school. Having the readiness to learn elementary school entrance well then the child can enjoy the process of learning activities and the opportunity / opportunity to deliver to achieve the best achievement in learning

Therefore, the Communication, Informatics, and Coding Office of Kampar Regency urgently needs improvement in order to fulfill the clauses of ISO 27001: 2013

Challenges in improving the performance of eddy current testing: Review

Eddy current testing plays an important role in numerous industries, particularly in material coating, nuclear and oil and gas. However, the eddy current testing technique still needs to focus on the details of probe structure and its application. This paper presents an overview of eddy current testing technique and the probe structure design factors that affect the accuracy of crack detection. The first part focuses on the development of different types of eddy current testing probes and their advantages and disadvantages. A review of previous studies that examined testing samples, eddy current testing probe structures and a review of factors contributing to eddy current signals is also presented. The second part mainly comprised an in-depth discussion of the lift-off effect with particular consideration of ensuring that defects are correctly measured, and the eddy current testing probes are optimized. Finally, a comprehensive review of previous studies on the application of intelligent eddy current testing crack detection in non destructive eddy current testing is presented

Adaptive Neuro-Fuzzy Inference System Model Based on the Width and Depth of the Defect in an Eddy Current Signal

Non-destructive evaluation (NDE) plays an important role in many industrial fields, such as detecting cracking in steam generator tubing in nuclear power plants and aircraft. This paper investigates on the effect of the depth of the defect, width of the defect, and the type of the material on the eddy current signal which is modeled by an adaptive neuro-fuzzy inference system (ANFIS). A total of 60 samples of artificial defects are located 20 mm parallel to the length of the block in each of the three types of material. A weld probe was used to inspect the block. The ANFIS model has three neurons in the input layer and one neuron in the output layer as the eddy current signal. The used design of experiments (DOE) software indicates that the model equations, which contain only linear and two-factor interaction terms, were developed to predict the percentage signal. This signal was validated through the use of the unseen data. The predicted results on the depth and width of defect significantly influenced the percentage of the signal (p < 0.0001) at the 95% confidence level. The ANFIS model proves that the deviation of the eddy current testing measurement was influenced by the width and depth of the defect less than the conductivity of the materials
