Analisa Kinerja pada Standalone Server dan Clustering Server Teknologi RAC (Real Application Clustering) dengan Algoritma DNS (Domain Name System) Round Robin Berbasis Oracle Linux 6.4 di Lingkungan Virtual
Full text linkABSTRACT –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
Making a "Pandhawa Lima" Puppet Puzzle Game Android based using Unity3D
No full textAs 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.

IMPLEMENTASI QR CODE VALIDATION PADA SISTEM INFORMASI SURAT PERINTAH PERJALANAN DINAS
Full text linkAbstract— 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

SISTEM MANAJEMEN DAN VISUALISASI SYSLOG PERANGKAT JARINGAN KOMPUTER PADA ICT UNIVERSITAS DIPONEGORO BERBASIS ELK STACK
Full text linkAbstract—Device monitoring is an important thing to manage networks. Information related network state or condition can be gathered through the device monitoring for administrators to make decisions regarding occurred events. Logs can be useful information to monitor network devices. Network administrator of Diponegoro University need a centralized log management system that can receive, manage, and analyze logs. This research identify functional requirements of log management system. Topology design and software that will be used by the log management system use DSR method. The next step is implementation of the topology, software, and application. The last step is testing the system and log management application. The results show that collecting centralized logs and processing these logs into information in the form of dashboards using ELK Stack application successfully implemented. The dashboard resulted by ELK Stack Application will be implemented on the web application using PHP programming language and Codeigniter framework. The test results show that system can receive logs and group the log according to the device location and the severity level of the log

DECISION SUPPORT SYSTEM BASED ON BCR METHOD FOR PROJECT TENDER
Full text linkThe procurement process became one of the important aspects for PT. PLN (Persero) to operate the company. One way to meet these needs is through the project tender. The tender process aims to get high-grade materials with the lowest prices that meet the criteria of efficiency PT. PLN (Persero). In order to simplify the bidding process required a decision support system. The method used in this system is Benefit Cost Ratio (BCR). Input in this application are the documents and the tender offer price from bidders with complete tender documents that have been validated by prospective bidders and then selected by the tender committee to make an assessment and validation winner. The output of this process is the winner of the tender project based on calculations Benefit Cost Ratio (BCR). Therefore, the method Benefit Cost Ratio (BCR) can be used as a decision support system to determine the winner of the project tender
Supervised Classification Karakter Morfologi Tanaman Keladi Tikus (Typhonium Flagelliforme) Menggunakan Database Management System
Full text linkTanaman 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.

PERBANDINGAN PORTABILITY, REUSABILITY, DAN INTEROPERABILITY PADA E-COMMERCE BERBASIS OPEN SOURCE
Full text linkThis paper will focus on comparison of portability, reusability, and interoperability values on open source-based e-commerce. The aim of comparing these three values is to find out which e-commerce has the best portability, reusability, and interoperability values. E-commerce software that will be tested are Magento 2.0, OpenCart 2.3.0.2, and WooCommerce 3.07. It has been chosen because this software are included in “The Top 10 Open Source e-Commerce Platforms” by CMS Critic website. Portability and reusability assessment is based on modularity, self-descriptive, and simplicity subfactor. The result obtained which e-commerce has the best value of the three factors tested is OpenCart with the best scores in the factor of portability and interoperability
