Orthodontics is a branch of dentistry. In orthodontic treatment, several analyzes are needed, one of them is cephalometry analysis. Basically, cephalometry analysis is done manually, but this method requires a lot of time. In line with this, a computerized application is needed as a solution. In cephalometry analysis some landmarks are used as reference fields. Orbital is one of the landmarks that are difficult to identify. Orbital is located at the lowest point between the region of the eye cavity and the lower edge of the Orbital bone. One way to find Orbital landmarks is to segment the Orbital region. The segmentation aims to clearly separate the eye regions and Orbital bone in the cephalogram image. Fuzzy C-Means Clustering method is a segmentation method that can produce a clearer region partition. For this reason, the Fuzzy C-Means Clustering method is applied to get better segmentation results of the Orbital region so that the results of identification of the correct Orbital landmarks are obtained. Based on the results of testing on 90 image data provide an accuracy of 82.2% identification results with a cropping template size of 180 x 180 pixels.Keywords—Cephalometry Analysis, Fuzzy C-Means Clustering, Landmark Cephalometry, Orbital

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)
