Sistem Trigger Database Pada SIAKAD Informatika
Get PDFTanjungpura University of EngineeringFaculty Pontianak particular use SIAKAD applications in the academic process. ApplicationsSIAKAD facilitate students to perform academicprocess as a process of inputting LIRS, LIHS,transcript Value and others. This application is to helpstudents because the students no longer bothered towrite all the subjects as in the old system but simplyby selecting options from the application. The systemwas developed to complement SIAKAD application isto use the trigger. Trigger serves as the commandfunction of data duplication. Any data that is enteredeither by students or faculty the trigger will make abackup copy of the database. Trigger requires asystem to be able to access the database residing on adifferent server by using Federated Storage Engine. Federated Storage Engine to be a bridge that connectsto the database backup trigger. Each event occursInsert, Update and Delete the backup database triggerwill access through the Federated Storage Engineexecutes the same event on the backupdatabase.Trigger tested with black-box method, thetest results when doing Insert, Update and Delete thetrigger is executed and the process the same on thebackup database
PERANCANGAN APLIKASI SMS (SHORT MESSAGE SERVICE) DENGAN ENKRIPSI TEKS MENGGUNAKAN ALGORITMA BLOCK CIPHER AES (ADVANCED ENCRYPTION STANDARD) BERBASIS MOBILE PADA PLATFORM ANDROID
Get PDFAbstract - In recent several years, there was a rapid development in mobile phone technology. One is the development of smart phone with many features and also complex operating system that similar to a computer. Although smart phones have many features that included in the operating system, but long or short messaging service known as SMS is still popular in use. SMS feature that still exist till today, bring out the question about the safety of information if someone wants to send a confidential information via SMS facility. The ease of exchanging information via SMS is misused by some people. Some people with a variety of ways to try to steal information that's illegal. Therefore, we need a way to secure the information that is confidential and important. Encryption process can be used to improve the SMS text message levels of information security. Currently, AES (Advanced Encryption Standard) is used as a standard for cryptographic algorithms. Therefore, it can be developed an SMS application with a text encryption using AES algorithm. Mobile-based applications built on the Android platform. The test results showed that the application can perform encryption of short messages with text to a particular destination number and can not decrypt the encrypted message. Application can help users to send short messages in a secure, fast, and easy.
ANALISIS QUALITY OF SERVICE (QOS) PADA JARINGAN INTERNET (STUDI KASUS : FAKULTAS KEDOKTERAN UNIVERSITAS TANJUNGPURA)
Get PDFQuality of service is theability of a network to provide better serviceto serve network traffic that passing throughit. From the results of a survey conducted bytaking a sample of the 2040 Quality ofService (QoS) for 16 days, the Internetnetwork at the Faculty of Medicine,University of Tanjungpura get value of 2.33at SSID Hotspot_FK and 2.53 at SSIDHotspot_FK2 with a standard category Fairin Telecommunications and InternetProtocol Harmonization Over Networks(TIPHON). For the average DownloadSpeed on SSID Hotspot_FK amounted to252.53 Mbps and 871.71 Mbps for SSIDHotspot_FK2. As for the average UploadSpeed on SSID Hotspot_FK amounted to99.19 Mbps and 372.55 Mbps for SSIDHotspot_FK2. Applications that used in themeasurement is the command prompt,wireshark, and google chrome which refersto the site speedtest.biznetworks.com andwww.pingtest.net. And the measurementresults can indicate the QoS parametervalues consists of packet loss, delay, jitter,throughput, and mean opinion source.Factors that could influence the networkQoS is attenuation, distortion, noise andbandwidth capacit

PERANCANGAN SISTEM TEMU BALIK INFORMASI DENGAN METODE PEMBOBOTAN KOMBINASI TF-IDF UNTUK PENCARIAN DOKUMEN BERBAHASA INDONESIA
Get PDFInformation will be easily to accessespecially from internet that has increased thenumber of various of digital information. It hasincreased need of user about information retrievaltools, which it can describe the most relevantdocument based on user question. Informationretrieval can support in managing and finding information effectively and efficiently. It designedto handle searching based on keyword from user.This implemented query expansion technique andterm weighting method with combination of TFIDF(term frequency-inverse document frequency).Query expansion is a method that increases theterm in query for improving search performance.Term weighting based on combination of TF-IDFgives more weight for more impotant term. In thissystem, searching query add based on synonim ofsearching keywords that the result is not onlydocument which have keywords, but also documentassociated with searching keyword based onthesaurus and root word. This system can find all ofrelevant document from available collection.Searching result sort based on document weighttoward to keywords that depict the similarity ofdocument with user question that it can befacilitating user to find information properl
Prototipe Sistem Identifikasi Kendaraan Bermotor Roda Dua (E-Razia) Berbasis RFID (Radio Frequency Identification)
No full textTwo-wheeled vehicle is a means oftransportation that is vulnerable to theft crimes. When the vehicle has successfully changed hands, thecriminals will seek to refine their crime operations.For example, by creating its own vehicle registration,so that the motorcycle can be sold like an officialproduct and to trick officers during raids vehicle. Tofacilitate personnel in identifying the vehicle, thevehicle identification system needs to be implemented.Until now, officers conducted raids are ineffectivebecause criminals can easily fool the officers byequipping vehicles with fake registration. Therefore,designed a prototype system of two-wheeled motorvehicle identification based RFID can help officers.RFID (Radio Frequency Identification) is a devicethat consists of the identification tag and readerwhere each RFID tag has a unique ID so that it isalmost impossible duplicated. The test results showthat the system can help officers to identify vehicles

The rapiddevelopment of information technology iscurrently supported by the importance of theneed for information. It can be seen from the development of today's internet network israpidly increasing. Informations thattransmitted is not meant for everyone. Alongwith the development of these technologies,security threats becomes more and morepowerful, particularly for the undisclosedinformation. Various threats in cyberspace suchas hacker, cracker, carder makes people worryabout the security of the information they sends.This concern that make the development ofinformation hiding techniques. One of the wellknown information hiding technique issteganography. In general, steganographymeans a technique and art of hiding a fact tocommunicate. By using steganography, secretmessage can be inserted into an unsuspiciousinformation and send it without being aware ofthe existence of the secret message. There areseveral criteria that must be considered insteganography is fidelity, robustness, andrecovery. Fidelity means that stegomediumquality has not changed much due to the insertion. The changes can not be perceived bythe senses
