Perancangan Sistem Pelayanan Informasi Berbasis Android dengan Algoritma Nazief Andriani (Studi Kasus : Universitas Katolik Santo Thomas)
Full text linkService is an effort to help prepare what others need. Or it can be interpreted that service is a series of activities or processes that fulfill the needs of others more satisfactorily. To simplify the services available at the Catholic University of Santo Thomas, it is necessary to build an android-based information service system with Nazief Andriani algorithm. This algorithm is able to find the basic words of each input so that it can produce a separate output or in other words the output issued right on target or on purpose. With this system, students no longer need to come to the administrative unit or via chat to get information about activities or complaints that are received or what they want to convey. So that this system is expected to make it easier for users to get accurate, efficient information and does not require a relatively long time, causing slow, limited and unresponsive service in providing answers
Memprediksi Jumlah Siswa Baru Menggunakan Metode Backpropagation (STUDI KASUS: SMK HARAPAN BANGSA KUALA)
Full text linkArtificial Neural Network (ANN) and time series data can be used for forecasting methods well. Artificial Neural Network is a method whose working principle is adapted from a mathematical model in humans or biological nerves. Neural networks are characterized by; (1) the pattern of connections between neurons (called architecture), (2) determining the weight of the connection (called training or learning), and (3) the activation function. The research objective was to obtain the best artificial neural network architecture, comparing the two methods of Backpropogation Neural Networks with the Radial Base Function Artificial Neural Network (RBF) method. This research is a research using real data (true experimental). This research was conducted at SMK Harapan Bangsa Kuala, which was obtained from 2015 to 2019. The results showed that for one iteration using the backpropagation method the result was 0,378197657 with a squared error 0.143033468, then the results achieved were not in accordance with the target
Perancangan Aplikasi Steganografi Menggunakan Metode Adaptive Minimum Error Least Significant Bit Replacement
Full text linkSteganography is a method to allow users to hide a message in another message in the form of digital media, the message to be conveyed is hidden in a digital media so that it is hoped that it will not cause suspicion from other parties who do not want to know the secret message the. There are two general stages in digital steganography, namely the process of embedding or encoding (insertion) and the process of extracting or decoding (revealing or revealing). The results obtained after the embedding or encoding process are called stego objects (if the storage media is only in the form of image data, it is called Stego Image). AMELSBR insertion method, the process is not the same as the LSB method. If the insertion process in the LSB method is done directly per pixel in its bytes, where the last 1 bit (LSB) per byte is replaced by 1 secret data bit to be inserted, but not by the AMELSBR method. In this method, the cover image will be divided into several blocks first. Each block will be 3 x 3 pixels or 9 pixels

With the handling of this web-based School Information System, the processing of new student registration data and student grades can be handled quickly and the presentation of information quickly and accurately to students, teachers and principals
Pengujian Metode Kuantitasi Untuk Melakukan Kompresi Citra RGB
Full text linkAt present the use of RGB images is a necessity in various fields. However, its use is constrained by a large file capacity, but it is possible to compress the image that is owned as needed. With the quantization method, the R matrix, the G matrix and the B matrix will be reduced, so that the number of bits used to represent the image will be reduced. Because the number of bits is reduced, the file size becomes smaller. The quantization method is included in the Lossy Compression category, so the compressed image cannot be decompressed again because there is information missing
