Abstract

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.

Abstract

The use of the internet, which is currently increasing dramatically, certainly brings the convenience of finding information. The increase in internet usage also eventually gave rise to cybercrime crimes, one of which was by spreading a URL or fake site to steal someone's personal data. The research done is how to build an Android-based application that can detect the security of a URL. The goal is that internet users, especially social media, can avoid cybercrime crime that wants to steal personal data. Making an application uses the Regular Expression method to analyze each line of the Webpage Source Code in the URL based on 8 criteria taken from the World Wide Web Consortium (W3C). The application was then tested with 10 phishing-charged URLs and compared with Kaspersky, McAfee, and AdBlock applications. Based on the results of trials and comparisons, applications that have been made are able to detect 6 or 60% of the 10 URLs. Kaspersky and McAfee applications can detect 70%, while AdBlock only detects 3 or 30% of 10 URLs that contain phishing.

Abstract

Aviation requires a very high level of security and safety, so that there is no problem that can harm various parties, one of the things that must be considered is about the transportation and handling of Dangerous Goods material. Existing handling system on the flight of dangerous goods systems where outside there is still a lot of risk of handling errors until there is data inaccuracy that can harm various parties, because almost all handling done manually. In addition, the plane does not want to delay and does not want to insert dangerous goods into the plane, so to anticipate the problem conditions, built a system that performs faster, easier and accurate handling, where the system uses PHP programmer language and utilize Telegram API as media Client Server. The built tool explains how to identify packaging, calculations and documents, this tool has reliability with the ability to calculate and identify faster than the manual way with average calculations whose value is significantly different. The values obtained by manually counting which is about 175 Minutes 8 Second or equivalent to 2 Hours 55 Minutes 8 Second and counting with the system  about 94 Minutes 44 Seconds or equivalent to 1 Hour 34 Minutes 44 Seconds, then more than 46% the results are different.

Abstract

Redundancy and robustness are the most common problems in a wireless network distribution system, network system problems that are not able to handle coverage areas in a large / wide coverage, so that the network users are easily disconnected from the connection and out of the server radius. These problems are caused by topology and wireless network distribution methods that are not in accordance with the needs and coverage of its users. However, adding a number of access points en masse to expand the network without being based on appropriate applied methods, is not necessarily able to minimize complaints from network users. Starting from the problems described in the previous paragraph, in this study a wireless distribution mesh system topology (WDS mesh) will be built to improve utility and network usage in the area / radius of the area between access points using wireless lines and minimize cable requirements which are generally the main constraints in network deployment and installation to areas that are difficult to reach. The topology built in this research will implement the wireless routing protocol that results from the analysis and observation process to expand the expansion of service areas to places that are difficult to reach. The wireless routing protocol method used in this study is the Made Mesh Easy (MME) method which is one of the developments of the Interior Gateway Routing Protocol (IGRP) method. Evaluation of the wireless routing protocol in the WDS mesh network topology will be carried out periodically to obtain the results of the analysis that will be used to re-configuring and re-routing to maintain the quality of the network remains realiable. Mesh clients will give feedback on the quality of service obtained based on observations according to IEEE 802.11 standardization. The parameters used are: Througput, Packet Loss Ratio, Latency, Jitter, MOS, Post Dial Delay and Echo Cancelation (EC)
