Abstract

Nowadays, cell phones or mobile phones have become a multipurpose tool. The developers of mobile phone/smartphone have added an assortment of features and applications that are very useful for the users. Nokia provides the opportunity for application developers by providing developers such as Qt SDK. Application developers can use Qt SDK to design and create applications that can run on mobile phones based on Symbian. In this research Qt SDK was used to create applications for monitoring a room using a camera and display it on a Symbian-based smartphone. Research also used webcam7 software to monitor the camera and display it on PC screen. The Symbian used was Nokia E71. The camera used webcam M-Tech camera connected to the PC via USB cable, and internal webcam. Virtual routers were used to make the laptop into an access point. Virtual routers created using the netsh command was typed at the command prompt laptop. Symbian smartphone was connected to the wifi on the laptop. By accessing the IP of the laptop, display on a webcam has successfully been seen through a symbian smartphone monitoring application created using Qt SDK.

Abstract

TV broadcast systems are migrating from analogue to digital broadcasting system. Some countries in the world have completed this migration since a few years ago. America decided to stop broadcasting analog television in 2009. In Asia, Singapore launched this technology in 2004 and Malaysia implemented in 2006 (Depkominfo, 2009). With so many countries are migrating to digital broadcasting system, there are many business models that can be referred for organizing digital television broadcasts. In this writing, several business models that are used in the world will be reviewed and analyzed and the results can be a reference to determine the appropriate business model according to the organizers.

Abstract

Computer Networks is an important course as a basis in computer science. This is because at this time all activities are associated with the use of network system or communication system. In the course of learning in Computer Networks, students are often difficult to understand network concepts, especially with many layman terms for students. The term IP, Subnet Mask, Gateway, and Router are the terms widely used in network. To better understand the use of the IP, Subnet Mask, Gateway, and Router, it should be given concrete examples of the application day-to-day. Such as setting the IP, Subnet, Gateway, and Router on a PC connected to the network, it is hoped that students can quickly understand. This prototype used some Virtual Machines considered to represent the need for the creation of multiple virtual machines in one computer. The resulting prototype is expected to be useful in learning the Networking matter in Computer Networks subject. Research successfully created 2 Virtual Machines in 1 computer, with the network in both Virtual Machines isolated and not connected to the Internet.

Abstract

It is known that traditional architectures are a product of human conception full of culture and philosophy, while modern architectural concepts prioritize functionality and simplicity that tends to be simple or quick. Now the architectural concept slowly changes according to the conditions of time, then so is the existence of works of architecture that also changes. This condition can be found in almost major cities in Indonesia, where many houses or buildings built still in traditional architecture theme but combined and matched with modern architecture concept. One of many diverse cultures of Indonesia archipelago architecture that has evolved is West Java. There are a lot of people trying to apply the concept of Sundanese traditional house in their residence. Shifting sacred values in traditional concept seems indeed to be lost along with the differences in modern human civilization.
