Abstract

ABSTRAKUntuk menghindari pihak ketiga yang tidak berwenang, berbagai solusi keamanan telah dibuat untuk mengamankan kerahasiaan pesan atau informasi, salah satunya adalah steganografi. Penelitian ini mengusulkan teknik pembangkitan kunci dalam proses steganografi. Secara umum steganografi menggunakan konsep kunci simetris, dimana metode ini membutuhkan pihak ketiga dalam proses pendistribusian kunci rahasia. Solusi dari permasalahan tersebut penulis mengusulkan metode baru dengan menggabungkan pembangkitan kunci rahasia menggunakan RSS pada jaringan nirkabel dengan steganografi untuk menyembunyikan pesan. Sistem yang kami usulkan diterapkan pada kondisi statis dan kondisi dinamis untuk menguji kinerja. Pada proses pembangkitan kunci didapatkan waktu rata-rata 110,52 detik untuk membangkitkan kunci. Pada proses embedding, waktu komputasi rata-rata untuk 65.536 karakter adalah 6,38 detik untuk menghasilkan citra stego. Pada proses ekstraksi didapatkan waktu komputasi rata-rata 0,63 detik untuk mendapatkan pesan rahasia.Kata kunci: RSS, Key Generation, Symmetric Cryptography, Steganography. ABSTRACTTo avoid unauthorised third parties, variety of security solutions have been created to secure the confidentiality of messages or information, one of which is steganography. This study proposes key generation technique in the steganography process. In general, steganography uses a symmetric key concept, where this method requires a third party in the secret key distribution process. The solution to this problem the authors propose a new method by combining secret key generation using RSS on a wireless network with steganography for hiding messages. To test performance, our proposed system is used in both static and dynamic condition. In the key generation process, an average time of 110.52 seconds was obtained to generate keys. In the embedding process, the average computation time for 65,536 characters is 6.38 seconds to produce a stego image. In the extraction process, an average computation time of 0.63 seconds is obtained to get a secret message.Keywords: RSS, Key Generation, Symmetric Cryptography, Steganography.

Abstract

In principle, a video codec is built by implementing various algorithms and their development. The next generation of codecs involves more artificial intelligence applications and their development. DCNN (Deep Convolutional Neural Network) is a multi-layer NN concept with a deep learning approach in the field of artificial intelligence development. This study has proposed a DCNN with three hidden layers for intra-frame-based video compression. DCT and fractal methods were used to compare the performance of the proposed method.  The training image (obtained from the average of all down-sampled frames) is divided into several square blocks using the square block shift operation until all parts of the image are fulfilled. All pixels in each block act as input data patterns. After the training process, the trained proposed DCNN was then used to construct the feature and sub-feature image obtained through the max function operation in the feature bank and sub-feature bank. These feature and sub-feature images were then a spatial redundancy minimizer with specific manipulation techniques and simultaneously a quantizer without converting the frame's pixels to a bit-stream. The result of this process is a compressed image. Experiments on the entire dataset resulted in AAPR (Average Approximate Performance Ratio) of 147.71%, or an average of 1.5 times better than other methods. For further studies, the performance improvement of the proposed DCNN is performed by modifying its structure so that the output is direct in the form of feature and sub-feature images. Another way is to combine it with the DCT or fractal method to improve the performance of the result.

Abstract

The recirculating aquaculture system (RAS) is a land-based aquaculture facility, either open-air or indoors, that minimizes water consumption by filtering, adapting, and reusing water. Solid organic matter from fish waste and food waste directly becomes waste that needs to be eliminated because it is a source of increasing total ammonia nitrogen (TAN), total suspended solids (TSS), total dissolved solids (TDS), and also has an impact on reducing dissolved oxygen (DO). RAS requires a water level control system so the fish tank does not experience water shortages or floods, disrupting the aquatic aquaculture ecosystem. In this study, small-scale RAS is modeled using a 3-coupled tanks system approach with a tank configuration that follows the most straightforward RAS water recirculation process (fish tank, mechanic filter, biofilter). Clean water from the reservoir flows into the fish tank through a protein skimmer. This study applies the fuzzy logic controller (FLC) to control the water level in the protein skimmer and biofilter tanks by controlling the position of several valves where the placement positions of the valves have been determined according to system requirements. The study results show that the tuned single-input FLC has the best average output response characteristics with ts=50, h1ss=49.98, ess=0.02 in protein skimmer and ts=4700, h1ss=39.75, ess=0.25 in the tank system.
