The low understanding of nutritious food choices among elementary school children remains a problem because it impacts their health, learning abilities, and future eating habits. A similar situation was found at SDN 3 Picungremuk, where students often choose flavored foods without considering their nutritional content. This community service activity aims to improve students' nutritional knowledge through education on the concept of "Isi Piringku" (My Plate). The implementation stages include identifying needs through observation and discussions with teachers, developing materials tailored to children's development, conducting interactive socialization, and practicing how to assemble a balanced meal plate using visual media. Evaluation was carried out through pre- and post-tests accompanied by food selection simulations. The output showed a significant increase in understanding. Before the education, most students were unable to combine foods correctly. After the activity, all participants were able to assemble a meal plate according to the principles of balanced nutrition. These findings prove that the use of visual media and hands-on practice is an effective method for instilling healthy eating habits in elementary school children.

Application of Multi-Layer Perceptron neural network to fault classification in high-voltage transmission lines is demonstrated in this paper. Different fault types on protected transmission line should be detected and classified rapidly and correctly. This paper presents the use of Discrete Wavelet Transform energy features combined with zero sequence current magnitude as input features for neural network classifier. The proposed method uses eight extracted features to learn hidden relationship in fault signal patterns. Using proposed approach, fault detection and classification of all 11 fault types could be achieved with high accuracy. Improved performance is experienced once the neural network is trained sufficiently with 1188 fault samples, thus performing correctly when faced with different system conditions. Results of performance studies show that proposed neural network-based classifier achieves 96.18% average accuracy, which demonstrates that it can improve the performance of conventional fault classification algorithms, which in turn can provide more efficient solutions in the management and protection of high voltage electrical systems.
