Abstract

Writing notes on paper is fun because we can simply write whatever we want on it. Writing notes in the digital media is also advantageous for it can be shared directly. If we can combine the two functions, it will be more profitable. Therefore, the author wants to combine the benefits of writing as you wish like as on paper with contemporary digital writing. Somehow, writing using PC cannot be done at any time due to the needs of both electrical connection and space availabilty. Therefore, Smartphone or tablet is the right choice because it is not tied to two needs. The Smartphone to be selected is the one built with android platform for ease of note transfer compared to other platforms.

Abstract

Having a professional certificate in information systems and information technology fields means having the recognition for related skills and knowledge requested by the industry. Some countries and institutions have tried to bridge these needs by organizing conferences and seminars. Information systems department of Bina Nusantara University always tries to meet those needs. One effort is to introduce the Enterprise Architecture method initiated by Bernard for use in the course of information systems and information technology strategic planning. The results of this activity suggest that obtaining international certification requires the implementation of learning in a referenced standard. This approach is expected to accelerate the acquisition of professional certification for graduates majoring in information systems and technology.

Abstract

High increment of information system needs for company goes in line with the high demands of increasingly competitive and rivalry of industry. Corporate investment needs automatically increase to meet the demanding needs of this system. New developments in systems and technology can not be ignored by companies because it gives a very high economic boost in the competition. On the other hand, in line with the development of information systems is the development of Open Source applications as a cheaper alternative for enterprise use. With so many alternative of Open Sources requires companies to be more observant of selecting the best applications that meet the company needs and can be quickly implemented. This study presents the best approaches to select the best Open Source applications for companies, such as literature review, implementation and evaluation of e-learning Open Source application.

Abstract

The high increment of competition currently requires companies to have more values to offer to customers. Company must also truly understand what the core of the companies is as the reason of customers continuing the cooperation with the company. In its growth of knowledge management it clearly provide direction and a real acceleration to the company. The biggest problem is the lack of the ability of companies to see and identify the main knowledge and the main core in the company. This study discusses the best approach to identify the existing knowledge in the company as the basis for the development of the companies and for the construction of knowledge management system.

Abstract

This article discusses aout the knowledge management system implementation as growth tool at PT Intimap. The purpose of this study is to give solution to problems faced by PT Intimap, related to knowledge and the resources they own. Method used for the system development is the SDLC. Analysis shows that PT Intimap is a company with vast amount of knowledge. However, the knowledge has not been managed very carefully. Hence, there is a need to an integrated system, where all employees can put their knowledge and look for what they want to know within the system.

Abstract

The variation in illumination is one of the main challenging problem for face recognition. It has been proven that in face recognition, differences caused by illumination variations are more significant than differences between individuals. Recognizing face reliably across changes in pose and illumination using PCA has proved to be a much harder problem because eigenfaces method comparing the intensity of the pixel. To solve this problem, this research proposes an online face recognition system using improved PCA for a service robot in indoor environment based on stereo vision. Tested images are improved by generating random values for varying the intensity of face images. A program for online training is also developed where the tested images are captured real-time from camera. Varying illumination in tested images will increase the accuracy using ITS face database which its accuracy is 95.5 %, higher than ATT face database’s as 95.4% and Indian face database’s as 72%. The results from this experiment are still evaluated to be improved in the future.

Abstract

International employment standard requires higher quality of graduates, which can be achieved through high quality academic standards. As we know there are still a large number of graduates of Indonesian higher education rejected to work in global industry. Besides having low GPA, lots of graduates are considered lacking technical skills, interpersonal skills, and international experience. Indeed, the main weakness factor is the low English proficiency of graduates. We need a breakthrough that develops our academic standards of higher education to obtain international quality. Yet, there are challenges to face by the government, such as rebuilding the national system (establishing elite institutions), internationalizing higher education (globalizing the institutions or cross-border trades of education services), as well as enhancing private participation by repositioning the private sector. To overcome these challenges we need to build a strategic partnership of transnational education using online programs, which can obtain mutual benefit for the collaborating institutions. This article discusses about how to increase academic quality of graduates in Indonesia or in other Asian countries.
