Abstract

Information system is one of the most important things that can help every companies to improve the performance of their company. The Directorate Generate of the Treasury is one of the government agencies that already use information systems to support their performance to handle the entire transaction of state budgeting and also they provides information systems to serve their users. That system must have a priority of the security and reliability. To ensure that the system has both of the priority, it is necessary to holding of the information systems auditing to ensure that capability level of their governance. The author doing the audit of information system using framework of COBIT 5.0 and doing measurements with Capability Level. EDM 01 (Ensure Governance Framework Setting and Maintenance) and EDM 02 (Ensure Benefits Delivery) are the two main processes of that government needs to do an audit, because they want to make sure that the system can running well and can deliver every benefits to their users. Based on the measurements that have been done using a capability level, both of the main processes are stalled on level 4 and could not reach the level of target on level 5 because there are some activities that cannot going well and can be inhibit the others process to reach their goals.

Abstract

The Korean language is one of the most enthused language these days, mainly caused by the Hallyu wave. In traditional language learning techniques, flashcards are often used to help memorize simple syllables. Nowadays, online flashcards are used as a replacement for the traditional flashcards, which are proven to be more effective in many ways. However, the lack of use of appropriate methods to learn a new language will result in slower learning process. Therefore, by implementing a suitable method such as the Leitner method to an online flashcard will improve the learning process. The Leitner method sets aside the questions that can be answered easily and allows users to focus on questions that cannot be recalled consistently by distributing a set of questions in five different sections. Every question that can be answered by the user is moved to the next compartment, where the question will be repeated after a specified period of time. System usability scale is used to measure the usability of the application. This application has been successfully designed and built using the Leitner method to give the user the suitable interval of time for learning with flashcards and achieved a system usability scale score of 82,5. Index Terms— Leitner, Online flashcard, Laravel, Korean language.

Abstract

The aim of this paper is to get high accuracy of stock market forecasting in order to produce signals that will affect the decision making in the trading itself. Several experiments by using different methodologies have been performed to answer the stock market forecasting issues. A traditional linear model, like autoregressive integrated moving average (ARIMA) has been used, but the result is not satisfactory because it is not suitable for model financial series. Yet experts are likely observed another approach by using artificial neural networks. Artificial neural network (ANN) are found to be more effective in realizing the input-output mapping and could estimate any continuous function which given an arbitrarily desired accuracy. In details, in this paper will use maximal overlap discrete wavelet transform (MODWT) and graph theory to distinguish and determine between low and high frequencies, which in this case acted as fundamental and technical prediction of stock market trading. After processed dataset is formed, then we will advance to the next level of the training process to generate the final result that is the buy or sell signals given from information whether the stock price will go up or down. Index Terms—stock market, forecasting, maximal overlap wavelet transform, artificial neural network, graph theory, backpropagation.

Abstract

The XP (eXtreme Programming) model is best suited for the development of information systems projects that require rapid adaptation to changes that occur during application development compared to the SDLC Waterfall model. XP is also suitable for fewer team members and is in the same location in software development of medical record. Software development should be well planned, so that the software obtained quality and in accordance with the needs of users. The selection of the right framework will determine the success of software development, thus avoiding patchwork in application development. Step by step of research methods for medical record software are Planning, design, coding, testing and software increment. Studies conducted in this study include: library study, interviews, observation, document examination. Next do an analysis of the aplications made, and check the document to get a picture of the system created. This is done as an analysis and system design conducted by researchers. Selection of the right framework at the time of application development to bridge between the developer side and the user side, so that the developed application can be completed on time. In this research use eXtreme Prorgamming framework which focused on development of medical record, because eXtreme Programming more emphasis on software development and system design with CRC (Class Responsibility Collaborator). XP framework that every step always involves users, programmers, and parts of testing so that the applications created can be completed in a timely manner and in accordance with the needs of users.

Abstract

XY adaptive routing protocol is a routing protocol used on UTAR NoC communication architecture. This routing algorithm adapts shrotest-path first algorithm, which will forward will not be able to work optimally if the closest route no longer have enough bandwidth to continue the packet. Packet will be stored inside the router and forwarded to the nearest router when closest route has enough bandwidth. This paper suggest TTL based routing algorithm to resolve this issue. TTL based routing algorithm adapts XY adaptive routing protocol by adding several parameters on RTL UTAR NoC and additional bit in each packet sent by router. This additional bit and parameter will be used by TTL based algorithm as additional factors in choosing alternative routes inside the communication architecture. Use of TTL on TTL based routing different from use of TTL on communication network. Packets that carry TTL value that equal to Maximum TTL will be route using XY adaptive routing protocol. TTL based routing algorithm has shown better performance compared to XY adaptive routing on some of the experiment done using MSCL NoC Traffic Pattern Suite. This research also proves that TTL based routing algorithm cannot work optimally on small-scaled architecture.

Abstract

The mobile indoor robot guidance system is a mobile robot which can assist users to find the desired position or location indoor or inside particular shed where Global Position System (GPS) failed to perform. Robot guidance system has many features in order to make the system useful for all of the users. The type of user who can make use of this system is mostly the disabled user and the user which is unfamiliar with the environment or the map. There is also potential usage inside the shopping mall or the big office spaces with the capability of displaying the advertisement during guidance process. This work deploys robot guidance system using geo-magnetic and Wifi methods for Indoor Positioning System (IPS). Although DC motors can generate interference to the magnetic sensor, the proper shields are adequate for the system. The metal shields for the DC motor can minimize the deviation from 6.41n T or about 16.74% for non-shielding motors to 2.86 n T or about 10.56%. Based on this research, mobile indoor robot guidance system can be implemented using various methods of IPS including geo-magnetic. Index Terms—mobile robot, indoor positioning system (IPS), Wifi multilateration, geo-magnetic positioning, disabled user.

Abstract

There are a lot of things that must be considered when determining specifications of computer components to make sure those components chose are working compatible. According to a survey conducted to 78 respondents, about 72.5% of the respondents prefer to buy a built-up computer. The reason is because of a lack of knowledge of computer components and how to assemble computer properly. This research aimed to develop   a recommendation system that able to give recommendation of buying computer based on compatible components to be assembled, with the available budget, so that people who do not know computer components can also buy a assembled computer. The Genetic Algorithm was chosen for making this recommendation system because this Algorithm gives more alternative solutions through the process of crossover and mutation compared to the Greedy Algorithm which doesn’t produce a solution by trying all alternative solution nor  Exhaustive Search on Brute Force Algorithm which takes a long time to find optimum solution. The recommendation system of computer components specifications based on the budget available has been successfully developed using Genetic Algorithm and achieved 75.75% user satisfaction. Index Terms— Computer Components, Genetic Algorithm, Greedy Algorithm, Recommendation System.
