Publisher : Institut Teknologi Dirgantara Adisutjipto

Sign Language is a language which prioritizes manual communication, body language and lip movement for communication. People who usesign language for communication aredeaf and mute people. Sign language in Indonesia is Sistem Isyarat Bahasa Indonesia (SIBI) and Bahasa Isyarat Indonesia (BISINDO). BISINDO has a unique clause pattern that isSOPA (Subject, Object, Predicate, Adverbial). The clause pattern of BISINDO is just for deaf and mute people who know and understand it. Because there are some different structures between Indonesian language and BISINDO, itis neededlearning media which can translate from Indonesian language to BISINDO. Finie State Automata (FSA) is a method which is able to recognize pattern sentence classification in Indonesian language. FSA method is NSA (Non-DetermisticFinie State Automata) that is otomata with characteristics as a state. NFA is used to give introducing structure pattern sentence in Indonesian language. Sentence pattern which is produced from NFA produces eight sentences pattern which are arranged as requisites ofBISINDO translation. The result of research which is experimented by sign language researchersas many as 90% can translate well and appropriate with BISINDO sentence pattern, 10% explain that it is not appropriate with translation of sentence pattern and sign language model. Based on the data, it can be known that media of BISINDO sign language learning based on web using method of translation automata can be used for learning media.

Publisher : Institut Teknologi Dirgantara Adisutjipto

Information technology that is increasingly developing today must be balanced with the similarity of information data. Information security is obtained by applying cryptographic techniques, Vigenere Cipher is a key symmetry algorithm that uses a substitution technique that uses two letters encoding the original message. Vigenere cipher has a weakness because it uses short keywords and its use will be repeated. In this study, we will discuss the modification of the vigenere cipher algorithm and one time pad by adding a key elongation process as done in the RC6 algorithm. The results of the study will produce new variations in data security by combining the vigenere cipher algorithm and vernam cipher with key expansion algorithm RC6

The unprecedented outbreak of COVID-19 has become a grave concern worldwide because of its highly infectious nature. Besides extensive research on developing vaccine or medicine to prevent this virus attack, many technology-based solutions are also getting more importance as no one knows till date how to put a full stop on it. Being first conceptualized in 2008, blockchain technology gained enormous popularity in the cryptocurrency domain. However, nowadays, blockchain has also become popular in the healthcare domain as a privacy-preserving and data authenticity technique. The primary goal of our experiment is to develop a framework which can utilize the features of permissioned blockchain and maintain the fully controlled sharing of confidential health record to exhibit the health status and COVID-19 history of a patient using a mobile QR code based solution. So, the administrative team of any public place can be aware of the health condition of any people who are using this platform to prevent the unaware and hidden contagion of COVID-19. This article is the first of its kind to propose such a method to aid in solving this crisis. In our experiment, we have shown that Hyperledger Fabric as a base technology along with a robust user registration algorithm and data accessibility can solve the problem under consideration with a minimal health record of the patient. The proposed architecture also offers the patient more control over the health record, where the healthcare service provider assures the authenticity of the data, and the intrinsic feature of the blockchain technology makes it immutable.

Publisher : Institut Teknologi Dirgantara Adisutjipto

The keyword is one or a group of words used by websites to improve your visibility on search engines. The selection of keywords from the results displayed by Google's keyword planner still not match the expectations of the webmaster, so that needs to be determined the choice and order of priority keywords which will be optimized beforehand. Therefore, a system that supports webmasters in making decisions on choosing keywords that will be optimized previously for search engines is needed. The methods used in this research is Analytical Hierarchy Process (AHP) to find the weighting parameters and Simple Additive Weighting (SAW) applied to find the final value and rank. The results showed that the system is running as expected, so it can be used as a basis in support of the decision of the webmaster in determining the priority of the optimization of keywords that will be worked out with the results of the comparison between the manual system with 100%.

Publisher : Institut Teknologi Dirgantara Adisutjipto

In general, video compression only compresses video files without compressing the audio files in them. This results in the compression process not being maximized.This study discusses the process of compressing video and audio files to get maximum compression. The application built is a web-based video compression software utilizing FFmpeg to do the compression process by breaking down the original video which has a resolution of 720 to 4 files, namely 720, 480, 360, and 240 resolutions. The test is done by comparing the compression results only to video files and compressing to video and audio and there is a 1-2 MB file size difference, whereas when compared to the original file, there is a 5-20 MB size difference. In addition to conducting this test also performed compression testing on different devices and obtained relatively similar results on all devices. Test the image quality on the compressed file obtained the image quality results in the standard video compression below 30dB results.

Wireless network distribution is the right solution to disseminate network services in places and areas that are difficult to reach by cable networks. The effort to add a number of access points is intended to increase the coverage area of a network service so that the signal coverage can be even and broad. The development and improvement of wireless network users have made management and user management activities not easy, because of the way wireless technology works in the operational delivery of its packages, sorting and dividing the packages into 3 parts. Among them are packaged in the form of management, control, and data. Whereas if the management prioritizes data without considering management and control, the emergence of vulnerability in network distribution activities will occur when users are increasingly populated. To facilitate the flexibility and mobility of centralized wireless network users, this study utilizes VLANs that will be implemented at OSI Layer 2 to facilitate the classification of user-profiles, subnetting, securing, and roaming features between access point devices and their users. This research in its testing uses QoS parameters that refer to ITU G.165 / G.168 to monitor the quality of services provided. The parameters used in the measurement of interconnection include Throughput, Packet Loss Ratio, Latency, Jitter, and Delay. If the test is declared successful and complete, it is continued by analyzing and evaluating the results of the study in the hope that the system will successfully cluster the users based on the user characteristic dataset
