Decline in quality caused by daily use of facilities and infrastructure owned by an organization will certainly disrupt its function in supporting the performance of the organization. The solution that came from the research that has been conducted before is to develop android applications called Infiremis (Infrastructure and Facility Reporting Management Information System), that can be used to report damage to facilities and infrastructure and to track the status reporting. This android application was developed to be used by students, lecturers and staffs of Faculty of Computer Science Brawijaya University which those users has different background persona. Therefore, the usability of this android application need be tested to find out the value of effectiveness, efficiency and satisfaction of the application to fulfill its purpose. This research was conducted mainly to discover the result of usability testing towards the android application of infrastructure and facility reporting management information system. Based on Usability Testing that has been done show that the level of effectiveness and satisfaction of Infiremis respectively is 97,14% and 89,7%, whereas for the efficiency score is 89,9%.

The Connectivity Between Leap Motion And Android Smartphone For Augmented Reality (AR)-Based Gamelan Frihandhika Permana; Herman Tolle; Fitri Utaminingrum; Rizdania Dermawi

The smartphone development today makes the gadget not only used as a communication tool but also as an entertainment tool such as to play games and play music. The development of the smartphone also supports many technologies that can be run on the smartphone itself, such as Augmented Reality (AR), for example. There are some studies evaluated the AR application combined with Leap Motion, but those studies were using the SDK alpha of the Leap Motion Corp. that is now no longer accessible for the developers to use. This research is meant to overcome such a problem. The method proposed in this study is a technique to connect the Leap Motion with Android for Augmented Reality application. This paper also evaluates the technique used to connect the AR technology to Leap Motion so it can be a visual instrument simulation, which applied to the Gamelan traditional music instrument. The experiments resulted in the accuracy rate of the application of 96.43% for right-hand movement and 97.86% for the left-hand motion. The high accuracy result obtained in the research can be a promising result for the future research.

High Performance of Polynomial Kernel at SVM Algorithm for Sentiment Analysis Lailil Muflikhah; Dimas Joko Haryanto

Sentiment analysis is a text mining based on the opinion collection towards the review of online product. Support Vector Machine (SVM) is an algorithm of classification that applicable to review the analysis of product. The hyperplane kernel function of SVM has importance role to classify the certain category. Therefore, this research is address to investigate the performance between Polynomial and Radial Basis Function (RBF) kernel functions for sentiment analysis of review product. They are examined to 200 comments using 10-fold validation and various parameter values (learning rate, lambda, c value, epsilon and iteration). As general, the performance for polynomial kernel of 88.75% is slightly higher than RBF kernel of 83.25%.

Determining Optimum Production Quantity on Multi-Product Home Textile Industry by Simulated Annealing Gusti Eka Yuliastuti; Agung Mustika Rizki; Wayan Firdaus Mahmudy; Ishardita Pambudi Tama

Production planning is a plan aimed at controlling the quantity of products produced. Production planning is very important to be carried out by the company so that the production will always be controlled. It is very difficult to plan production with a variety of product variations because each product certainly has a different demand value from its customers. This has become a complex problem so an algorithm is needed to overcome these problems. Simulated Annealing can produce optimal solutions more effectively and efficiently. Production costs generated by applying Simulated Annealing are Rp. 6,902,406,000, - for all types of products, which is better than existing condition.

Analysis of Brawijaya University Academic Information Systems Acceptance on the User Characteristic, System Quality, Support of Top Management and Information Technology, Perceived Usefulness, and Perceived Ease of Use Yusi Tyroni Mursityo

Sistem Informasi Dosen (SIADO) as an academic information system for Universitas Brawijaya lecturers are not fully optimized and used since many perspectives about the system, such as system quality complaints and itâ€™s not obligated to use by the University leaders even many benefits can be obtained. This research conducted to describe the factors on SIADOâ€™s user acceptance in five variables, namely is user characteristic, system quality, top management & IT support, perceived usefulness, and perceived ease of use, using descriptive statistical analysis. Data collection techniques with offline questionnaire were distributed using paper from 96 Universitas Brawijaya lecturers. Validation and reliability were checked with statistics methods and descriptive statistical analysis is implemented to measure the level of categories on each variable to provide calculation and information based on data centralization and dissemination, and acquired categorized data. The results show that all five variables receive high category on SIADO acceptance, which indicates the user perception all five variables are good to be used as a consideration tool in receiving the actual use of the system.
