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.

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

This research purpose is to design a Knowledge Management System (KMS) in Bina Nusantara IT to facilitate knowledge sharing and knowledge management dashboard view to see the development of employee knowledge achieved in KMS. The high turnover rate caused the walkout knowledge. The knowledge is not well structured so that employees often have difficulty in searching for knowledge. Methods of the research conducted by the method of Software Development Life Cycle (SDLC), model iterations. The next step is formulating a study literature to find references to these problems. Then do a system design in the form of UML diagrams user interface and database. The results achieved in the form of KMS-based design to support knowledge sharing among IT BINUS employees. The conclusion from this study is that spread knowledge can be identified, stored and reused. Through this system, documentation of knowledge is optimized so that it can be a solution for walkout knowledge. There are a variety of KM applications in the system, such as Blog, Wiki, Forum, and Document.

Abstract

Banking world wants to help companies accelerate transaction receipts and disbursements, of the money they save in the bank. Bank account is a means to save money and transact safely and practically. If there is a large payment to the supplier, the company does not need to carry a lot of cash to the suppliers place, simply by giving a check to the supplier, and vice versa. E-Reconciliation is a service from XYZ Bank in the form of a delivery payment transaction data to the customer server periodically. Data delivery, safe and secure, to customers is an important factor in the process of reconciliation, one safe and secure way is to send the reconciliation report via encrypted email facility. With the delivery of the payment transaction data, customers can automatically reconcile the data. E-Reconciliation including new services in banking and is expected to add value to XYZ Bank among other competitors. In addition, it is expected to be many dealers and sub-dealer/reseller of customers who are interested in using E-Reconciliation services, so as to improve the balance of CASA.

Abstract

In certain circumstances children need to get therapy for supporting their growth and recovering their health. There are at least three types of therapy which are physiotherapy, occupational therapy and speech therapy. The existence of ornamental plants are believed to bring positive effects on therapy for children in condition that the ornamental plants concern positive and negative effects of the therapy activities. This study tried to determine the relationship between the types of therapy activities with the choice of ornamental plants. The result showed that the diversity of colors and scents of different types of plants can improve therapy facilities for children by concerning the therapy characteristics and the compliance with plant characteristics.

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

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

Operating System is an important software in computer system. For personal and office use the operating system is sufficient. However, to critical mission applications such as nuclear power plants and braking system on the car (auto braking system) which need a high level of reliability, it requires operating system which operates in real time. The study aims to assess the implementation of the Linux-based operating system on a Single Board Computer (SBC) ARM-based, namely Pandaboard ES with the Dual-core ARM Cortex-A9, TI OMAP 4460 type. Research was conducted by the method of implementation of the General Purpose OS Ubuntu 12:04 OMAP4-armhf-RTOS and Linux 3.4.0-rt17 + on PandaBoard ES. Then research compared the latency value of each OS on no-load and with full-load condition. The results obtained show the maximum latency value of RTOS on full load condition is at 45 uS, much smaller than the maximum value of GPOS at full-load at 17.712 uS. The lower value of latency demontrates that the RTOS has ability to run the process in a certain period of time much better than the GPOS.
