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.

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%.

Regions having higher level of welfare do not always have better indicator values than other regions having lower level of welfare. The problem is the lack of information related to the indicator values needed to determine the health level. Therefore, clustering using health data becomes necessary. Data were clustered to see the maximum or the minimum level of similarity. The clustered data were based on the similarity of four morality indicator values of the regional health level. Morality indicator values used in this research are infant mortality rate, child mortality rate, maternal mortality rate, and rough birth rate. The method used is Agglomerative Hierarchical Clustering (AHC) - Complete Linkage. Data were calculated using Euclidean Distance Equation, then Complete Linkage. Four clustered data were grouped into two clusters, healthy and/or unhealthy. The result, combining from all clusters into two large clusters to see healthy and unhealthy results.

Today's wireless communication system is a trend for the information society. This is inseparable from communication needs with high mobility and low costs. One of them is the Wireless Local Area network with the IEEE 802.11 standard. Wireless LAN is a communication technology that uses radio wave transmission media by utilizing free space as a transmission line. The transmitted signal is strongly influenced by distance, frequency, transmitter power, receiver sensitivity, and antenna gain. A loss occurs in the process of transmitting data from the sender to the recipien. In order to no loss that occurs, it requires a good performance, and a wide coverage area. The purpose of this study is to analyze the QoS data, calculate the coverage area, receiver power, and compare the results of theoretical calculations with the measurement results. The analysis results show the average throughput for each data rate of 6 Mbps, 15 Mbps and 35 Mbps at 383.8 kbps, 328.2 kbps and 329.8 kbps. The average delay is 5.28 ms, 4.81 ms and 4.66 ms. The average packet loss is 2.83% ms, 2.66% ms and 2.16% ms. The average jitter is 0.036 ms, 0.032 ms and 0.014 ms.

Because the growing of mobile technology in recently days, technology practitioners are required to be able to create a variety of devices and media that support the mobile technology. Application developers compete to create mobile applications that have a variety of features, including video call, voice sending, image sending or text messaging. Developing of mobile applications have an impact on using of Short Message Service, although using of Short Message Service began to shift, but the Short Message Service feature cannot be abandoned, because Short Message Service is a standard feature carried by mobile devices (mobile phones). For this reason, we need to develop Short Message Service Broadcast middleware as an intermediary for Short Message Service communication between web technology and mobile devices. This technology is using for disseminating information between systems that have been built with mobile devices via Short message service. Broadcast system will produce information about new student admissions, That will be received directly by Senior High School Students through their mobile phones. The Middleware can send message broadcast in real time to more than 500 cellular numbers automatically with an average time of 13 seconds for one message. The advantage of using this technology is direct configuration with Python Back-End. Meanwhile, Technology for message inbox still requires further configuration.

Many companies need a storage system that can be accessed in real time by all parts of the company. Most digital data storage methods today still use conventional methods where data is stored on an external hard disk or public cloud. Storage with external hard disk media makes accessing data difficult and has the risk of data loss when storage media is damaged. On the other hand, the storage method using public cloud requires an internet connection with large bandwidth requirements and the company still has to spend a budget on renting it. This study aims to design digital data storage methods using a private cloud that can be accessed in real time by all parts of the company without having to spend a budget on hiring a storage media and renting an internet connection with large bandwidth requirements. A private cloud was built using OpenStack Swift as an object storage service provider and Rclone as a cross-platform computer data management application. The results of this study are the creation of a private cloud that runs object storage services using Swift storage objects with relatively light and high scalability to meet the needs of storing data effectively and efficiently. A private cloud-based data storage media with relatively light and high scalability to meet data storage needs. Data storage media that can be accessed easily without having to use an internet connection with large bandwidth requirements.

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
