Abstract

This design of a computer software is a development and continuation of the software made on the previous research (2009/2010). However, this further research developed and expanded the scopes of testing more on the Siclic Group, Isomorphism Group, Semi Group, Sub Group and Abelian Group, Factor Ring, Sub Ring and Polynomial Ring; developed on the OSP (Open Source Program)-based. The software was developed using the OSP-based language programming, such Java, so it is open and free to use for its users. This research succeeded to develop an open source software of Java program that can be used for testing specific mathematical Groups, such Ciclic Group, Isomorphism Group, Semi Group, Sub Group and Abelian Group, and Rings, Commutative Ring, Division Ring, Ideal Sub Ring, Ring Homomorphism, Ring Epimorphism and Fields. By the results, the software developed was able to test as same as the results from manual testing.

Abstract

Library information system analysis and design for public senior high school XYZ in South Tangerang aims to identify needs of data and information about library operational transaction in the school. The result of requirement analysis was used to build a computerized system supporting the run of library business process. The analysis and design focused on solving the problems, such difficulties in finding book location, book availability, and else. Rational Unified Process was used for the information system development methodology and the result of requirement analysis was documented by using unified modeling language; user interface was also designed. This information system was expected to ease the library in doing its activity by serving the information related to book searching, book availability, book tracking. Besides, it would also fasten the process of book borrowing, book returning, and new book registration.

Abstract

The purpose of this research is to reduce the damaged material, applying the concept of FIFO for retrieval of row materials, and accelerate the search and also to simplify the detection of raw materials. Software development method used involves three main parts namely the method of analysis, design and literature. Analysis methods including survey of the running system, an analysis of survey findings, identify information needs, identify system requirenments. The design method approach to Unified Modelling Language (UML). The results is an inventory application that uses Radio Frequency Identification (RFID) tags as a replacement label where RFID tags can store data. Conslusions from this research is minimizing the company’s financial losses due to storage of raw materials and minimizing time to search raw materials using RFID that also can provide actual and accurate information for the company.

Abstract

This study developed a model of batch scheduling involving the unavailability machine to minimize setup costs, cost of preventive maintenance and the cost of rework in a stable machine. This model is considered necessary in order to understand the effect of the unavailability machine for production runs and to understand the effect on the batch production schedule. The results of this study indicate that the first and last run will not give single batch. Given a hypothetical example of how the model and algorithm developed solve the problem instance.

Abstract

One of the required resources in IT development projects is the human resource. Human resources has a role and an enormous influence on the process and the success of IT projects. By conducting a literature review and analysis of the factors of human resources, it is obtained the factors that influence the operation of IT projects. The factors may include factors that can be absorbed and factors that cannot be absorbed. Weaknesses in human resources are weaknesses that can be pressed or elaborated in such a way so as not to interfere the performance of the project. Performance of the project is one aspect that determines the quality of a project. The more positive the value of the performance of the project, the more positive the value of the quality of a project.

Abstract

The role of knowledge in an effort to developing and maintaining an organization has been strong regarded as a very important asset. Bina Nusantara is an organization that puts the human resources and paperwork as the main resource to perform maintenance on existing Knowledge. The problems that occur in Bina Nusantara is the high turnover rate leads to knowledge walkout. The purpose of this study is to design and implement features of Knowledge Management System (KMS) in Bina Nusantara organization specifically to facilitate knowledge capture, knowledge sharing, and document knowledge to nurture the development of knowledge that occurs in the environment Bina Nusantara. KMS is expected to prevent the knowledge walkout that due to the high turnover rate at Bina Nusantara. The methodology used in this study is the use of literature study and application design for KMS using Microsoft SharePoint 2010 technology. The conclusion of this study is to take advantage of features available in Microsoft SharePoint 2010 as a KMS media at Bina Nusantara become more optimal and easy Knowledge document search.

Abstract

In general automotive development, especially car, PT Astra Daihatsu Motor (ADM) continuously improves quality and service to supply vehicles in Indonesia. To support the improvement of quality and service, PT ADM continues to improve technology-based system to assist in providing vehicle parts of production process requirements. Therefore Purchasing division is very important in this process. Besides, supplier is a very important role in making and supplying parts for the company. PT ADM has a new system used to improve bidding process. Based on the discussion, price was not the only thing significant. There were other things to consider, especially in selecting the right supplier.  Realizing the system does not cover all areas, therefore, it needs Decision Support System with AHP method to filter suppliers. So that, the company will automatically have good supplier. At least, the supplier meets company standard, especially purchasing department. This research concludes that using AHP Method is very effective for filtering supplier so that the company can make sure that only capable supplier or supplier which meets company standard may join the tender to supply the goods or parts. This paper combined AHP Methodology as the first selection using pairwise scoring and Analysis Sensitivity Methodology used to take decision which supplier is in line with project requirements.

Abstract

This research aims to develop a system to monitor moving objects via web. The moving objects could be owned by individuals or company and can be used and managed independently. The system consists of three subsystems namely Mobile Geographical Location Sender (MGLS), Main Geographical Location Information Control (MGLIC), and Geographical Location Information User (GLIU). MGLS functions as geographical sensor. It retrieves GPS data and sends periodically to MGLIC as the main controller via 3G service. MGLIC is the receiving server and designed as web server as well. The web server is the host of a control application that processes GPS data that was sent by MGLS. The data is stored in a database and is centrally displayed. The processed information can also be used by GLIU, as another user that needs the information. Experimental test shows that the system can function according to the design.

Abstract

 Light intensity may affect the image quality of an object that can cause barriers in doing preprocessing to improve the image quality of a digital image. Furthermore, this would also be an impact on subsequent processes, such as sorting images according to the needs. Light intensity influences the reflection of light which translates into an image. This gives an impact on successful segmentation process. Examples of the success and failure of segmentation are presented in this paper.
