Abstract

IT Project’s succesfulness can be measured from some factors such as project’s time completion, project’s cost and project’s quality. These 3 factors, at least  should be as planned, means that on time, on budget and on quality, or  better than it has agreed. That’s why a regular project progress update has become a very important factor because it can be used by management to control the project, as well as an alert mechanism or early warning sign whether or not the project is on track or off track. This paper adopts the earned value analysis (EVA) that is used to monitor IT project progress, because EVA is a simple formula whilst able to provide a comprehensive information to support decision making.

Abstract

XYZ Company has a program to predict leasing income that only predict in constant condition where every tenant assumed for leasing renewal. This research is done to build accurate income prediction system that accommodate in making strategic decision towards the company. Premier data collecting is through direct interview with the company management. The analysis is through data training from the previous years to build neural network model. The analysis result shows that this model has produced error total value that is smaller than the previous error total value in years before. Therefore, it could be concluded that data mining with neural network technique that produced more accurate leasing income that could help the company making decision based on the hidden information in the database.

Abstract

Business use internal control to guide their operations, safeguard assets and prevent abuses their system. Management is responsible for designing and applying five elements of internal control. The results from the evaluation of Internal Control in Production Control System and Cost System are the company has a good enough internal control in both their systems, such as, implement the segregation of duties, effective and efficiency in their manual operation procedure, controlling their documents and assets. But one thing the company needs to be done is the using of pre-numbered form. Most of all their forms have not been a pre-numbered form.

Abstract

Fuzzy logic is a method in soft computing category, a method that could process uncertain, inaccurate, and less cost implemented data. Some methods in soft computing category besides fuzzy logic are artificial network nerve, probabilistic reasoning, and evolutionary computing. Fuzzy logic has the ability to develop fuzzy system that is intelligent system in uncertain environment. Some stages in fuzzy system formation process is input and output analysis, determining input and output variable, defining each fuzzy set member function, determining rules based on experience or knowledge of an expert in his field, and implementing fuzzy system. Overall, fuzzy logic uses simple mathematical concept, understandable, detectable uncertain and accurate data. Fuzzy system could create and apply expert experiences directly without exercise process and effort to decode the knowledge into a computer until becoming a modeling system that could be relied on decision making.

Abstract

Article discusses about the design and implementation of procedural content generation using java, especially the generation of virtual city. It is applied by using L-System to generate the elements of the city and also using some images as the base models. This method is proven to be more effective because it can produce almost unlimited variations of city in short amount of time without any needs to modify the application. The result of this application is a road map which can be used in many areas such as virtual reality, games, or other related purposes.

Abstract

Problem faced by SD IPEKA Tomang is not reaching its predicted target in English subject. This is caused by less understanding among students in important parts of English which reflected in making sentences or writing essays. Teachers have difficulty in explaining about grammar usage to students, which is the basic knowledge in making sentences. In order to avoid this problem, SD IPEKA Tomang is adding or replacing the teaching media into a computer media. In doing this analysis and designing of e-learning is using ADDIE Model approach. This research is done through stages of analysis, design, and development. Analysis stage uses Gap Analysis approach to understand the needs of e-learning.

Abstract

The design of e-Board was undertaken to meet the necessary of information between colleagues that nowadays has become more essential and vital especially in a team work that applying distributed asynchronous co-operative work system. In which, members of the team are distributed in time and space; therefore information should be well distributed to support the cooperative work between them. The research was applying analysis and design methodology. The analysis methodology was undertaken through literature study, current system observation, questionnaire survey to users to identify characteristics of the current and entailed information distribution media. The design methodology was undertaken through database, features, system, and screen layout design. Results of the research found that the information distribution media for team work which has applied distributed asynchronous co-operative work system should have the ability of private access for each member, better organization in information categorizing, structured information for task assignment, and supporting member's mobility. In conclusion, the application has been expected to help task assignment, distribution and organization of information in the distributed asynchronous co-operative work system to be easier and simpler.
