Abstract

Organization X is an organization working in the field of education from kindergarten to high school and vocational secondary school. Organization X are now starting to implement an IT system for all business processes that exist in the organization. All the IT services are intended to facilitate the organization's business processes, and the services provided to consumers can be brought to its best. The problem that occurs in Organization X related to the management system is still manually operated, IT equipment such as hardware, network and servers do not meet the requirements to operate well. That problem requires a risk analysis to provide a proper plan of IT services that will be used by the Organization X.In this thesis, the risk analysis assessment is performed based on the condition of the current IT services in Organization X, so as to determine the if Organizational X can assist the planning process of IT services in the future. The analysis is based on comprehension of the business model and strategy, an identification of IT Audit Universe, Control Objective Plan and Organize 1-3, as well as evaluating IT risk factors found. The process of risk analysis is performed using the method of Global Technology Audit Guidelines (GTAG), COBIT 4.1 Plan and Organis 1-3, OWASP Risk Methodology.Based on the examination, a number of IT risks in the Organization X were found, i.e. IT people are not fully involved in determining business goals, resulting in IT Division can not provide maximum role in giving an idea of the progress of IT-related organizations. No particular team established to plan the long-term IT services, resulting in no clear plan on a long-term IT of an organization.

Abstract

The learning process can be done by utilizing multiple media, such as sounds, images, and animation. In general, the available learning media only use one medium that is either images or texts. If you only use one medium, the learning process becomes less effective. Combining some elements of these mediums will complement each other, therefore this thesis create an interactive learning media.This application have 3 menus i.e. illness, digestive system, and test. The simulation was made interactive with hover, click and drag with the mouse, and by pressing the key on the keyboard. The test menu contains multiple choice and hangman. The test menu is created so the user can remember about material that has been provided. This application was created with Adobe Flash CS6 and actionscript 3 as the programming language. Based on the results of the testing, the application can be run sufficiently and can perform all the functions. The results of the survey content, memory and subjective satisfaction has a 85% of score because of easeness of use and clear navigation. A hurried user often had difficulties in doing the test because they didn’t read the instructions given.

Abstract

PT ABC is a company engaged in the production of reinforcedconcrete. In carrying out its business processes, the company isusing the server, network, software, hardware, PC software. Withthe disruption of one of these systems, the data processing will beannoyed at having to manually process data and perform theinput to the database after the system can run normally again.Looking at the situation and condition of PT ABC, did not rule outthe occurrence of risks such as damage to data integrity andcontinuity disruption of business processes.In this thesis conducted a risk analysis of the IT continuity andmonitoring of PT ABC. Risk analysis using the framework of ISO31000, for process analysis and its use COBIT 4.1 controlpractices, and use risk rating methodology (OWASP) forcalculating the value of risk. There are 7 risks found from analysis. One risk that has highseverity is the company did not have those who has responsibilityto monitor irregularities. Two medium risks are the company didnot have business continuity plan, and also a framework to buildthat plan. Four risks with low severity are the company did nothave an offsite backup, did not have a priority plan, no trainingfor employees to upgrade analysis skills, and never update ITcontinuity plan.

Abstract

Visual Novel is an interactive fiction game comprised of static images, sounds, and video combined. However, almost all of visual novel available are only accessible after completing the installation process on the platform defined by the development of that visual novel. Besides, authoring tools specialized for visual novel making are mainly based on desktop. Through this development, the authors would like to provide a widely accessible application which is available over the web and delivering ease of use of visual novel authoring tool. Availability of playable visual novel is also included to be one advantage of playing visual novel hassle-free.The results obtained from this application, among others, can upload and manage files necessary to be used in the visual novel project as its resource, create a visual novel through the provided editor, publish created visual novel, and play all published visual novel.

Abstract

than SQL is the general idea of this Hadoop implementation. The advancement of technology generates growing amount of data and demands a new method to process the big data. The performance of this hadoop implementation was also compared with that of SQL to prove hadoop’s novelty in processing big data. Moreover different hadoop’s implementations – such as various number of nodes, use of a combiner, and use of different block sizes – were evaluated.Hadoop was implemented for five queries (or problems) in processing the library circulation data. Those five problems are finding the numbers of borrowing transactions categorized by the audio-video types, collection types, titles, locations, and users’ departments.Some conclusions can be drawn based on the hadoop mapreduce implementation. Hadoop’s performance tops SQL’s when large data are being processed. The more the number of computer nodes, the faster the mapreduce application is to complete its execution. Use of a combiner can speed up the application’s execution. The arrangement with full data blocks can give better execution time than that with non-full data blocks does. In this hadoop implementation, the execution time using the block size of 128 MB is smaller than that of 28 MB and 512 MB.

Abstract

Programming in embedded lighting domain is commonly done using the C language with the Object Oriented programming paradigm at Philips Lighting. However applying that paradigm in combination with the low-level language like C creates a conceptual gap between the requirements and design and actual implementation. This results in reduced source code readability and maintainability. Functional programming paradigm was expected to alleviate this problem by reducing the gap and enhancing readability. A proof of concept was built on an advanced, IP-connected, digital LED driver (Power over Ethernet) device. The actual code was inspired by the rule-based decision engine concept developed by EnLight.Based on the hardware specifications of the device, the existing code to communicate with, and adherence to the functional paradigm, Lua was chosen to build the proof with. The implementation of the decision engine was altered to exploit characteristics of functional programming, such as representing actions as functions rather than as an enumeration value, using the common filter function to replace loops, and many more.The proof of concept was able to run in the device. It was also relatively more readable and maintainable. However, it was slightly slower, less memory efficient, and less capable in dealing with low-level problems such as garbage compared to the engine in C language.
