    ABSTRACT –A standalone server is a server that runs applications and databases on the same computer or server. As a service provider, the technology on the server is required to continue to develop in line with the needs. Therefore, a server clustering architecture was developed to serve the needs of clients on a larger scale. One solution to this problem is by implementing the RAC (Real Application Clustering) technology provided by Oracle 11gR2. RAC technology can fulfill client needs by using Round Robin DNS (Domain Name Server) algorithm. Then, this technology can help add new servers and recently assigned servers as cluster members. Also, RAC has advantages of memory storage for database storage. Based on the results of tests that have been done, server clustering has better quality according to a standalone server. Testing is done using QOS (Quality of Service) testing which is carried out on the network and also on load tests using TPM (Transaction per Minute) which is carried out on the database

    Abstract— Quick Response Code (QR Code) is a two-dimensional barcode that is able to provide more information than a one-dimensional barcode. Smart phone technology that develops very fast with advanced camera facilities equipped with scanning and decoding qr code features. The camera reads the QR code in five parts, namely pattern, alignment, timing pattern, quiet zone, and data area. The five sections used the qr code library to translate back in numbers or letters quickly. Compared to one-dimensional barcodes, qr code is more useful because it can store numbers or letters, while one-dimensional barcodes can only store numbers. The advantage of the QR code that can store numbers and letters is the choice of the company in using the QR code as a support system for official travel orders made in a website-based program

    As technology evolves, games become a media of entertainment that many people are interested in today. In addition to being entertainment, games can also be used as media broadening. Especially the insight of cultural heritage that is almost eliminated by the era and technological developments.  Wayang culture, children and adults are unfamiliar with the knowledge/stories about Wayang. Therefore, by utilizing the game as a medium that is easily accessible by various communities, in this research the author will design and build a game that brings together the cultural insight of Wayang, namely Wayang Pandhawa Lima. Combined with Puzzle genre games, users will be faced with fragments of puzzles that depict the figures of Wayang Pandhawa Lima. Where after completing the puzzle fragment that has been arranged, the user can read the information of the puppet that they have compiled. The creation of Wayang Pandhawa five puzzle game developed by Multimedia Development Life Cycle (MDLC) includes concept, design, material collection, manufacture, testing, and distribution. The creation process is done using the Unity 3D software that works on smart phone devices with the Android operating system. This application has been tested using Blackbox method as well as user testing with questionnaire method to 15 responodents. The result of this final task is that the application has been running according to the needs with a user interface value of 79.11% well categorized, usability aspect value of 84.67% well categorized and user experience aspect value of 84.44% well categorized. Keywords: Game; Android; Pandhawa Lima; MDLC; Unity3

    Supervised Classification Karakter Morfologi Tanaman Keladi Tikus (Typhonium Flagelliforme) Menggunakan Database Management System

    Get PDF
    Tanaman Keladi Tikus memiliki potensi medis tinggi dan bermanfaat dalam penyembuhan berbagai penyakit, seperti kanker payudara, kanker rahim dan leukemia. Tanaman keladi tikus memiliki keragaman genetik rendah karena pada umumnya tanaman ini diperbanyak melalui pemisahan bonggol secara vegetatif. Salah satu metode peningkatan keragaman genetik antara lain mutasi iradiasi sinar gamma. Uji coba peningkatan keragaman genetik ini menghasilkan data karakter morfologi dari tiap klon tanaman Keladi Tikus. Untuk menemukan pola dari data karakteristik morfologi tersebut, maka perlu dilakukan klasifikasi berdasarkan tingkat kesamaan dari data-data klon tersebut. Klasifikasi sebagai salah satu teknik data mining yang terukur, dapat dipercaya dan memenuhi suatu standar yang telah disepakati. CRISP-DM adalah standarisasi data mining yang digunakan pada penelitian ini. Untuk mengembangkan aplikasi klasifikasi data Mining tersebut digunakan bahasa pemrograman PHP dan Database Management System yaitu MySQ.. Berdasarkan penelitian dan setelah dilakukan pengujian, maka didapat perangkat lunak  yang dibuat dapat digunakan untuk melakukan perhitungan tingkat similaritas dan melakukan klasifikasi pada dataset morfologi tanaman Kelati Tikus.

    Footprint analysis for foot type classification using FPA methods produces the output of footprint images and various calculated parameters that have been performed. These data need to be stored and processed in order to be reused when needed. Manual data storage is very slow and error-prone, also it makes storing and processing the data difficult. This study aims to design a medical record information system that can store and manage patient data and detection results of flat foot disease. System development methodology used is Extreme Programming method consisting of requirement analysis, design, implementation, and testing. From this research produced a medical record information system that can assist in storage and data processing of the result of flat foot detection. Based on the test results with black box method can be concluded that the produced information system has worked well and meet every function required

    Loyalitas merupakan hal yang penting dibangun setiap perusahaan untuk memenangkan kompetisi. Salah satu cara untuk meningkatkan loyalitas pelanggan adalah dengan memberikan reward kepada pelanggan terbaik. Konsep RFM (recency, frequency dan monetary) dapat dipergunakan untuk menentukan pelanggan terbaik dan mengukur nilai loyalitas pelanggan. Metode Comparative Performance Index (CPI) diaplikasikan untuk menentukan bobot relatif variabel RFM dan menentukan nilai atau peringkat masing-masing pelanggan. Untuk membentuk pengelompokan pelanggan digunakan algoritma K-Means. Berdasarkan pengujian ISO 9126 model RFM (Recency, Frequency dan Monetary) merupakan kriteria penilaian yang tepat untuk mengukur nilai loyalitas pelanggan. Proses pengelompokan pelanggan dengan algoritma K-Means membutuhkan proses yang cukup lama bergantung pada jumlah transaksi sesuai dengan periode pengelompokan. Namun dengan adanya sistem, proses pengelompokan menjadi sangat efisien dibandingkan dengan melakukan pengelompokan secara manual. Hasil pengujian dengan ISO 9126, sistem yang dikembangkan sudah bekerja sesuai dengan fungsinya.   Kata kunci : Decision Support System, Pemilihan Best customers,  RFM,  Comparative Performance Index (CPI), K-Mean
