The development of information technology now allows one to exchange information through a computer network. One that is used in exchanging information is a chat application. The chat application is used to chat two people or more in realtime via the internet network. In exchanging information, a data security is needed, one of the data security that is done is encryption on the message. Encryption is done to change from the original message to a message that is not easy to read (ciphertext). Then a TEA (Tiny Encryption Algorithm) algorithm is applied.The results obtained in this study that the TEA algorithm can be implemented on chat messages for encryption and decryption of text messages. The process of testing encryption and decryption on messages is fast. Can be seen from the test table the application that encrypts text messages of various sizes using the same key produces a difference in the encryption and decryption time is not too large, with only a few seconds difference.Keywords—Chatting, Cryptography, TEA, Encryption, DecryptionDOI: 10.5281/zenodo.1468233

The wireless network is one of the best alternatives in building a network of computers that is practical, in some agencies and the commercial wireless network is used to support an existing wired network. But its implementation is still used cable network that became the backbone of the access point so that a client that is connected can access the internet. Wiring problems can be a considerable obstacle in places that are hard to reach.The wireless distribution system is a system for developing a wireless internet network without having to use a cable as a backbone for the access point but instead of utilize a wireless line of the access point. At the time of the wireless distribution system network, topology and network topology of the non-wireless distribution system is applied, will be on analysis using Wireshark, the QoS parameter application that consists of a Delay, Throughput, and Packet Loss.The testing performed against the clients who are numbered six (6) is each connected to the access point. Scenario testing is done i.e. the conditions streaming and download, made during the three (3) days. Of test results obtained, the wireless distribution system network topology has the value throughput, delay; packet loss is a little less useful than a non-network topology wireless distribution system. But the differences in the average value of the QoS parameters that are generated are not too significant.Keywords—Wireless Distribution System, Non-Wireless Distribution System, Quality of Service (QoS)

Current technological developments are very influential on the process of data distribution that is demanded fast because every second of information can change. One of the methods used in data exchange is to use data replication in a distributed database. The speed of the process and the number of rows that can be replicated in units of time are some of the things that can be taken into consideration when trying to determine how to replicate data in a distributed database.In replication, a software is used to find or more precisely track changes that occur in a database. After changes in one database are identified and known, then changes are made so that all databases are the same as other databases.This study implements two computers consisting of master and slave, each of which is a database server that is connected to each other in the network. The test results obtained in this study are that with the database replication, every data that is stored periodically always backups the slave computer.Keywords—Replication, Database, Distributed Database DOI : 10.5281/zenodo.1493829
