Abstract

 Tutoring institution is an organization which focuses in education. The objective of this institution is improving the quality of learning of all students to achieve the desired target. The operational activities of this institution consist of registration, scheduling, evaluation, and administration supporters. It will be less effective if the processes are done manually. Therefore, many institutions are starting to restructure the model of information systems to support the company’s operations. This study describes about designing an information system model using object oriented approach based on the methodology introduced by Satzinger, where each phase is represented by using UML diagrams. The result achieved in this research is to produce a general model of information systems in supporting the operations of a tutoring institution. Designing an information system that is compatible with business processes can maximize the company's operations to run efficiently and effectively so as provides a competitive advantage from its competitors.

Abstract

Entity relationship diagram (ERD) and data flow diagram (DFD) modeling are necessary parts in analysis and design of structured information systems in business. Definition of entities in the ERD, the process, and datastore in the DFD have well described in a lot of literatures. However, practically it is not easy to explain how to design ERD and DFD models so that the students well understand the modeling steps, especially in business applications. This study discussed step-by-step systematic approach to ERD and DFD modeling using "business event-driven" approach that is represented by the REA model, through structuring REA-ERD and REA-DFD. From the results we concluded that the logical design of ERD should be done before designing DFD, so that there would be perfect "balancing" between the entities in the ERD and data stores in the DFD. Consequently, the implementation of these steps needed to be tested both qualitatively and quantitatively in advanced researches

Abstract

Article presents analysis and design of software using Location Based Service (LBS) that is part of communication technology based on geographic position. The goal of the research is designing LBS application to be implemented on mobile device that has GPS (Global Positioning System) technology and uses GPRS (General Packet Radio Service) to connect to server for generating shortest path by Dijkstra algorithm method Fibonacci Heap. Software development method used is LBS application implemented on mobile device. Conclusion of the research has shown that shortest path generated using Dijkstra algorithm method Fibonacci Heap as single source shortest path is faster than Dijkstra algorithm and Bellman Ford.

Abstract

This article presents an application development of a Tactical Role-Playing Game based on AndEngine on an Android Gingerbread mobile device. The goals of the research are designing an entertaining application that implements artificial intelligence and AndEngine technology as well as presenting Indonesian cultures. The output of the research is a 2-dimension-based Tactical Role-Playing Game application implemented on Android Gingerbread mobile device and a game engine for creating items and skills of the characters for the game. On the application development phase, the research uses literature study, user requirement analysis, and similar game analysis. The research showed that the game application is developed using 2-dimension perception implementing artificial intelligence and AndEngine technology for having interesting control and appearance for users. In addition, it motivates other programmers for developing other game that presents Indonesian cultures, and uses conditional framerate for reducing battery usage on mobile device.

Abstract

Investment Information Technology (IT) has always been a primary objective of the business which is expected to provide value to businesses through its role as a competitive advantage and the creation of innovation. However, it is ot easy to measure how much value is successfully created, or determine whether the IT strategy is aligned with business strategy, or find out if the IT organization has a strategy that focuses on creating business value. Innovation Value of Institute (IVI) introduces a new concept known as the IT Capability Maturity Framework (IT-CMF) which can help IT organizations to align the business vision with the IT vision so that IT strategy could focus on value creation . the IT-CMF implementation which begins with the assessment of the maturity of IT organization can provide an overall picture, so that organization can prioritize the development of appropriate IT investments to support the value creation for the overall business.

Abstract

Regarding to: (1) the increasing region’s need in developing tourism destinations; (2) the needs of tourists in selecting appropriate attractions according to specified criteria; (3) the need of travel businesses to offer sights of interest in accordance with the needs of potential tourists, (4) the need to deepen and continue our previous research titled "Development of Tourism Destination Media Potential and Utilizing Local Resources in the Era of Autonomy and Regional Expansion ", we need to develop a complete database of tourism destinations in Indonesia that can facilitate those needs. We build a web-based database that is capable of storing complete information about Indonesian tourism destinations in thorough, systematic, and structured way. It is also able to classify a variety of attractions based on attributes such as: location (the name of the island, province, district), type/ tourism products, how to achieve the object, cost, and a variety of informal information, such as the ins and outs of the attraction area incorporated by the local or tourist experiences. The research will focus on deepening and refinement of the model and database structure design and implementation with the collection, processing, and data entry of primary and secondary data which amounts to approximately 140 tourism destinations in Indonesia. The research is arranged in stages as follows: (1) designing models and the database structure, (2) making a web-based program, (3) installation and hosting ; (4) data collection, (5) data processing and data entry, (6) evaluation and improvement/ refinement. Once developed, the database can be used as a starting point in the development of Data Warehouse, Decision Support System, and Expert System for Indonesian tourism industry.

Abstract

One of added values to compete in work and business is mastering English’s Language. To support the needs of an online teaching tool that can be accessed anywhere and is easy to use, an online teaching tool that uses Indonesian is made with an attractive multimedia display so that users do not feel bored and can monitor the development of the value achieved. The material presented is based on the structure tested in TOEFL. The method used in designing these applications is the waterfall method, ranging from data collection through questionnaires and comparative analysis of similar applications and then proceed with the design and development of applications and user satisfaction evaluation. It is expected that these applications can help in improving the English language proficiency as measured by TOEFL score achieved.

Abstract

Non destructive testing on piles can be divided into two main categories. The first category is to find out the integrity of the piles, such as pile integrity testing (PIT) and sonic logging. The second category is to find out the pile capacity, such as dynamic load testing/pile driving analysis. Since the early 1990s, the application of the tests was brought into practice and gained its popularity in Indonesia. However, the basic theory behind the testing has not been widely disseminated. This study tries to elaborate the first category of the testing, i.e. the pile integrity testing and sonic logging. The basic theory, the advantages and disadvantages, the application, the limitation and the interpretation of those techniques shall be discussed. Comparison on case studies of those testing methods also shall be given.
