Abstract

Anomalies may degrade network performance for specific network traffic. Because of its nature, it causes abnormal network traffic. Using the K-means clustering method, this study addresses the formulation of the problem of detecting network bandwidth usage anomalies. The objective of this study is to identify potential network traffic anomalies. This study uses the K-Means Method to predict the value of the network traffic anomalies that will appear. K-Means operates by repeatedly iterating based on the initial cluster entered, until the same cluster results are discovered. The results of the study indicate that predicting the occurrence of anomalies with K-Means will help suppress activities that impede network traffic.

Abstract

Puzzle is a game of rearranging pieces of picture objects, which can train creativity, order, and concentration levels. Problems in puzzle games will be more complicated when the size of the pieces gets smaller so that the number of pieces increases. The challenge is how to always make new puzzle arrangements and quickly reassemble recovery pieces. The focus of this research is to arrange puzzle pieces randomly and try to reposition the puzzle using the proposed method, namely DCD (Dominant Color Detection). The DCD method works by using the color histogram method to track the image based on the dominant color information. The Eucledian Distance method is then used to measure the level of image similarity . The similarity indication of the puzzle image is used to reposition the puzzle. Based on the test results, it is known that the accuracy of the repositioning results on the sample logo image, totaling 30 test images, is 100% successful in getting the whole image back according to the logo input image. This method has the opportunity to be used as an alternative to access security and also as a simple engine model for image search based on image fragments.

Abstract

The power quality is identified and monitored to prevent the worst effects arise on the electrical devices. These effects can be device failure, performance degradation, and replacement of some device parts. The deep convolutional neural networks (DCNNs) method can extract the complexity of image features. This method is adopted for the power quality disruption identification of the model. However, the power quality signal data is a time series. Therefore, this paper proposes an approach for the conversion of a power quality disturbance signal to an image. This research is conducted in several stages for constructing the approach proposed. Firstly, the size of a matrix is determined based on the sampling frequency values and cycle number of the signal. Secondly, a zero-cross algorithm is adopted to specify the number of signal sample points inserted into rows of the matrix. The matrix is then converted into a grayscale image. Furthermore, the resulting images are fed to the two-dimension (2D) CNNs model for the PQDs feature learning process. When the classification model is fit, then the model is tested for power quality data prediction. Finally, the model performance is evaluated by employing the confusion matrix method. The model testing result exhibits that the parameter values such as accuracy, recall, precision, and f1-score achieve at 99.81%, 98.95%, 98.84, and 98.87 %, respectively. In addition, the proposed method's performance is superior to the previous methods.

Abstract

Indonesia is the first Asian country to be appointed to lead the 20th global summit (G20 Summit) and it will be held in Bali, Indonesia. The successful implementation of the G20 Summit attracted public attention, triggering various kinds of public sentiment (opinion) regarding the G20 Summit. With public sentiment, the government can find out the views or opinions of the public regarding the G20 Summit that has been held. Public sentiment can be in the form of positive sentiment or negative sentiment, for this reason a process of classification and analysis of these sentiments is needed. The process of classifying public sentiment starts from the problem identification process, then crawling data to retrieve Tweets from Twitter, data preprocessing to process data, data labeling, KNN-based model training, classification model testing and evaluation. The results of the sentiment analysis show the results of the accuracy of 97.75% accuracy, 100% precision and 97.71% recall.Keywords: Sentiment analysis; K-Nearest Neighbor, G20 summit implementation AbstrakIndonesia merupakan negara Asia pertama yang di tunjuk untuk memimpin Konferensi Tingkat Tinggi Global 20 (KTT G20) dan dilaksanakan di bali, Indonesia.

Abstract

Segmentation is one of the important operations in the object recognition process. One of the well-known segmentation methods is image subtraction. This image subtraction process is carried out to separate the foreground object from the background object. Most studies use this method to segment static images. In this study, the performance of the subtraction method will be observed based on the dynamic image input of hand movements. The application of the subtraction method is used for segmentation operations based on different information on different frames with the aim of obtaining information on the hand area. The focus of this research is to compare the results of processing with the subtraction method on different types of inputs based on the nature of their constituent signals, namely analog video input (webcam) and digital video input (stored video). The success of processing on both video inputs is determined from the first segmentation processing that finds the hand area. Two test cases (various lighting levels and outdoor background) were deliberately chosen because they are closely related to the potential weaknesses of the image subtraction method. Based on the test results, it is known that the implementation of the subtraction method for analog video input (webcam) and digital video input on various tests of light and background quality which is quite complex, shows success in finding areas of moving hands.

Abstract

Sendangtirto Village is located in Kapanewon Berbah, Sleman D.I. Regency. Yogyakarta has an artificial reservoir/lake. The main objective of building a reservoir is to provide a conservation area and irrigation of rice fields. The existence of harvest sales activities through an auction system and the construction of joglos and gazebos around the embung, make the Sendangtirto embung worthy of becoming a tourist destination. Currently, the existence of the embung is not yet known to the wider public, besides that the public facilities available are still minimal. The PKM team took the title "Implementation of a Solar Charging Station and Digitalization of the Harvest Auction System to Increase the Number of Visitors at Embung Sendangtirto" and hoped to be able to overcome this problem. The Solar Charging Station was chosen because it uses renewable energy sources, is environmentally friendly and economical. The design is simple and easy to implement and operate. Meanwhile, to overcome the problem of the number of visitors, training and assistance will be provided in creating content on social media as a means of promotion. In addition, there is a need to create a digital harvest auction recording system. Through this PkM activity, it is hoped that it can provide education on the use of renewable energy for the community, increase horticulture sales from farmers and increase the number of visitors at the Sendangtirto reservoir.

Abstract

Permainan merupakan sesuatu yang tidak bisa dipisahkan dari kehidupan manusia, karena itu manusia disebut juga sebagai homo ludens atau makhluk yang suka bermain (Tedjasaputra, 2001). Salah satu sarana permainan yang dapat digunakan yaitu menggunakan teknologi komputer. Pada beberapa permainan yang berbasis komputer memiliki kelebihan yaitu pemain (user komputer) tidak perlu mencari orang untuk menjadi lawannya karena pada permainan tersebut terdapat kecerdasan buatan yang mengendalikannya. Kecerdasan buatan adalah suatu ilmu yang mempelajari cara membuat komputer melakukan sesuatu seperti yang dilakukan oleh manusia. (Kusrini, 2006). Salah satu caranya adalah dengan menggunakan algoritma minimax yang bekerja seperti pikiran manusia. Ia akan mengambil langkah yang terbaik baginya serta memberikan langkah terburuk bagi lawannya. Algoritma minimax bisa diterapkan pada permainan, salah satunya adalah tic tac toe. Pada permainan ini, pemain akan secara bergantian mengisi sel papan. Pemain dianggap memenangkan pertandingan jika berhasil mengisi 3 sel pada papan secara horisontal, vertikal, maupun diagonal. Jika papan terisi semua dan kriteria menang tidak terpenuhi, maka permainan berakhir dengan imbang. Berdasarkan hasil pengujian yang dilakukan dengan menggunakan algoritma minimax pada kecerdasan buatan yang diterapkan di permainan tic tac toe sebanyak 60 kali, hasil yang didapatkan adalah permainan berakhir imbang sebanyak 43 kali, dan kecerdasan buatan menang sebanyak 17 kali.
