Abstract
The Resonator is one of the techniques widely used to determine the dielectric properties of a material. It is due to the accuracy of the resonator technique as compared to the other methods such as open wave guide sensor, transmission method, and coaxial probe. The accuracy plays an important role in any measurement devices as this is one of the features to show that the device is competent enough to perform a specific task. So, as to cope with accuracy issues, two microstrip ring resonators were designed and prototyped to detect the dielectric properties of Material Under Test (MUT) in this study. Both utilize Rogers Duroid 4003C as the substrate for the dielectric sensor and is meant to resonate at 4 and 5 GHz in which the substrate possesses 3.38 dielectric properties and 0.0027 loss tangent. Several features in designing the resonator such as the coupling gap, d, and radius of the ring, R were taken into consideration. Those parameters were verified and validated through software simulation and measurement using Vector Network Analyzer (VNA) to achieve the expected sensor prototype to operate in the real environment. The measurement was made to test two known dielectric properties of MUT to demonstrate the sensitivity of the sensors. The outcome from the measurement was evaluated in terms of S-21 parameter. The dielectric measurement leads to a change in frequency response against different MUT. The measurement was extended to study the performance of the resonator through the R and d of the resonator in which these parametric studies were made by varying the R and d of the resonator with the presence and the absence of MUT. The outcomes from the measurement suggest the best R and d for the resonator in terms of dielectric permittivity.

Abstract
Camellia cipher is another symmetric block cipher which allows the encryption and decryption process to share the same key. The cipher permits a 128-bits input data with three different key size: 128, 192 and 256 bits. This paper presents two hardware design approach of Camellia cipher, which are FPGA and custom-based design approach. These approaches utilized design softwares of Altera Quartus II with device family of Cyclone II and Synopsys Design Compiler. The performance of Camellia crypto-core design is then been evaluated based on the implementation platform in terms of speed, area and power. With an equal base of 50MHz of clock frequency, custom-based design is found more efficient than FPGA-based design due to the execution time achieved with 8.46ns, which is faster than the latter that consumed double the time with 16.075ns. The custom-based design achieved 15.13 Gbps of throughput. Besides, the power consumption of custom-based design is 1.3519 mW which is lower than the FPGA-based design. In a nutshell, the design has successfully done as it achieved expected encryption and decryption outcomes with acceptable performance.

Published: March 2021

Abstract
In the current trend, machine learning has been used widely for network attack detection. The performance of a machine learning model depends on its training dataset and the dataset distribution. Network attack detection is one of the problems that usually suffer from the imbalanced data distribution. However, the effect of this imbalanced data is generally neglected by researchers. Therefore, in this research, we studied the impact of an imbalanced multiclass dataset to the machine learning performance. Five state-of-the-art machine learning algorithms were used in this study, and the classifiers that can classify the minority class or the majority class instances accurately were also identified. In this research, the performances of these classifiers were evaluated by using the performance metrics: true positive rate, false positive rate, precision, F-measure, ROC area, and classification accuracy. The results show that the J48 classifier outperforms the other four classifiers in every aspect. Besides, Naïve Bayes, J48, has also worked as the best classifier that able to classifies the instances of the minority class accurately.

AbstractThere are approximately 1.3 billion people in the world have visual impairment issue. They usually have to read printed material using Braille. However, there are limitations for these people when the material is not printed in Braille. Although there is much electronic equipment that can help them to read, the prices are too expensive to afford. Thus, this paper proposes an affordable mobile application which is designed for the visually impaired person. The mobile application is able to capture the image of printed material with a mobile camera. The captured image is then converted to text by using image-to-text conversion in Optical Character Recognition (OCR) framework. Finally, the text will be read out into speech format using text-to-speech conversion in Text to Speech (TTS) framework. As a result, a person who has visual impairment can understand the printed material which is not written in Braille through listening instead of touching. Some alert sound is provided to allow the users to know what exactly happened in the mobile application. It is user friendly for the visually impaired person since the designed system has sound for guideline so they can always get to know the process of the application.

Abstract
Brackish water aquaculture is an essential business in Aceh Tamiang Regency. Data and information about the brackish water business collected from selected villages in four regencies from April until August 2020. In 2019, the brackish water farmers run their business 91.1% as the traditional type of aquaculture, 2.0% as semi-intensive, and 6.9% as intensive practices. The traditional brackish water farm is depending on “toke” as the source of funding. Meanwhile, the last two types of businesses grew with rent and sharing system. The brackish water activities only give limited benefits to the local community because they highly depend on other regions for seed, feed, pesticides, and labor, and the local institution supports the brackish water business not yet created. This research recommends: the village’s government should develop and implement the regulation for the involvement of local people in business activities; the brackish water institution should be created in the location especially for water management, control water pollution, and sources of various information regarding brackish water business. The Village Business Agency (Badan Usaha Milik Gampong) should improve its capabilities and play a role in the village’s brackish water business.
