Publisher : Faculty of Computer Science (FILKOM) Brawijaya University

Abstract. Gerakan Nasional Orang Tua Asuh Scholarship offers a number of scholarship packages. As there are a number of applicants, a system for selection and recommendation is required. we used 3 methods to solve the problem, the methods are AHP for feature selection, SVM for classification from 3 classes to 2 classes, and then TOPSIS give a rank recommendation who is entitled to receive a scholarship from 2 classes. In testing threshold for AHP method the best accuracy 0.01, AHP selected 33 from 50 subcriteria. SVM has highest accuracy in this research is 89.94% with Sequential Training parameter are Î» =0.5, constant of Î³ =0.01 , Îµ = 0.0001, and C = 1. Keywords: Selection, Recommendation, Scholarships, AHP-SVM-TOPSIS

Review: A State-of-the-Art of Time Complexity (Non-Recursive and Recursive Fibonacci Algorithm) Imam Cholissodin; Efi Riyandani

Abstract. Solving strategies in the computation the time complexity of an algorithm is very essentials. Some existing methods have inoptimal in the explanations of solutions, because it takes a long step and for the final result is not exact, or only limited utilize in solving by the approach. Actually there have been several studies that develop the final model equation Fibonacci time complexity of recursive algorithms, but the steps are still needed a complex operation. In this research has been done several major studies related to recursive algorithms Fibonacci analysis, which involves the general formula series, begin with determining the next term directly with the equation and find the sum of series also with an equation too. The method used in this study utilizing decomposition technique with backward substitution based on a single side outlining. The final results show of the single side outlining was found that this technique is able to produce exact solutions, efficient, easy to operate and more understand steps. Keywords: Time Complexity, Non-Recursive, Recursive, Fibonacci Algorithm

Optimizing SVR using Local Best PSO for Software Effort Estimation Dinda Novitasari; Imam Cholissodin; Wayan Firdaus Mahmudy

Abstract. In the software industry world, itâ€™s known to fulfill the tremendous demand. Therefore, estimating effort is needed to optimize the accuracy of the results, because it has the weakness in the personal analysis of experts who tend to be less objective. SVR is one of clever algorithm as machine learning methods that can be used. There are two problems when applying it; select features and find optimal parameter value. This paper proposed local best PSO-SVR to solve the problem. The result of experiment showed that the proposed model outperforms PSO-SVR and T-SVR in accuracy. Keywords: Optimization, SVR, Optimal Parameter, Feature Selection, Local Best PSO, Software Effort Estimation

Belajardisini : The E-learning Framework Based on Gamification Concept Eko Sakti Pramukantoro; Widhi Yahya
Journal of Information Technology and Computer Science Vol. 1 No. 1: June 2016

Abstract. The lack of motivation and student engagement in the learning process are the Challenges in education today. E-learning is one of the methods used to resolve these issues.The E-learning, the digital based learning media, enable students to study every where and every time. Basically the e-learning is only used for repository of teaching materials and for evaluation. This kind of e-learning cannot motivateÂ the learning process. The development of e-learning must be done in order to increase the motivation to learn. The proposed solution extends the e-learning application with the Gamification approach. Gamification is adopted mechanism of the game in non game context. Typically, gamification is used in the business world. The Leaderboard, Challenges, and reward are components that are used to stimulate products sales by marketing. The reward will be given to the top rank salesman on the Leaderboard. This interesting concept can be applied to e-learning to stimulate the learning motivation

Information and Data Distribution System for Rural Areas of Indonesia Kasyful Amron; Achmad Basuki; Eko Sakti Pramukantoro; Widhi Yahya
Journal of Information Technology and Computer Science Vol. 1 No. 1: June 2016

Abstract. Internet becomes critical infrastructure in the distribution of information. The information is used for decision making and ensure the success of human activities. However, the distribution of information in rural Indonesia is inconvenient, because the digital communication infrastructure (internet) doesnâ€™t cover all areas in Indonesia. This problem causes the digital divide in Indonesia. This study proposes communications infrastructure and data transfer mechanism or media sharing that can be applied to a variety of rural areas conditions in Indonesia, which has limited communications infrastructure. The approach is to build low power digital carrier devices in the form of minicomputer and utilize Delay or Disruptions Tolerant Network (DTN) architecture. Testing results in the digital carrier node show that the data is successfully delivered. Keywords: Rural Area, Mini-PC, Delay Tolerant Network
