Abstract

In writing that I make with the title "Temperature Measuring Equipment Design Room With LM35 Temperature Sensor Using a Microcontroller AT89S51" about design for temperature data acquisition system that uses the basic components of an ADC, temperature sensor, Microcontroller AT89S51 and Seven Segment as a viewer facility. Temperature data acquisition system into the one thing that is very important in industrial activity, because it is a small part of a process control. Regarding the importance of system, so the temperature data acquisition system design that is capable of monitoring the temperature of a plant. The data will be a physical property measured temperature so as to be processed and displayed in the form of electrical systems used LM35 temperature sensor that is able to convert these quantities with the increase of 10mV / º C. To be able to design the system was first carried out the process of changing the temperature into an analog voltage using a temperature sensor LM35. After going through the process was strengthened by the signal conditioning, analog voltage converted into digital data using the ADC 0804. Digital data obtained is then processed by the Microcontroller AT89S51 and displayed, so we get some information about the temperature of the plant unit º C on a Seven Segment From system design, acquisition of temperature data showed that this system has the ability to measure the temperature of 25 º C to 100 º C by the error mean Average temperatures for the appointment of 0.266 ° C.

Abstract

Platform GNU / Linux and the growing popular in the community have proven to provide many alternative solutions that drive efficiency and be more user friendly. Creating a virtual operating system can be easy, we can determine the installation and existing applications on the main operating system and guest operating systems. Making this virtual operating systems to illustrate some important points which are able to learn and provide flexibility. It also outlines the processes of how to install operating systems and applications.

Abstract

The development of computerized technology in the education world increasingly fast. Even the education-education in our country are also taking a computer as one part of the lessons learned. With this method the computer approach to the children who performed early, and by taking the material they learn in the education-education in their schools, children can recognize and understand the computer further. As capital for them to face the times.

Abstract

Animation we often encounter was limited to the entertainment world, but also animation can also be used in other areas. For example in the world of business and commerce. With animation, the delivery to another party will not be boring. Animation applications is expected to help marketing the store to be able to explain the survey results, which can berdasasarkan from the field. In the writing of this research will be discussed how to make an animated multimedia marketing survey Harmony store at PT Graha Indah simple and attractive. This animation created using Macromedia Flash application program 8. Where used Macromedia Flash to create animations in the world of entertainment (entertain).

Abstract

Computers are a means for people to help all kinds of human activities in accordance with its use. Anyone used these facilities both individuals, corporate organizations, government installations and by those who use computers. But what if the computer's performance is affected by the lack of protection against electricity. In this case developed a device that UPS needed to overcome the problem of electricity computers. With UPS is expected to minimize all forms of electricity shortages on the computer used.

Abstract

Scientific writing is about the use of tin as an antenna amplifier in a network without cables based on the access point. Limited funds to set up a network, either using a cable or using a wireless antenna into the main factors using tin as a wireless antenna that can strengthen the wave from the receiving antenna (receiver) to the access point. Calculation can be an antenna that will be something that can not be ignored in order to obtain a good signal reinforcement.

Abstract

Algorithm development of three-dimensional process itself, of course, is the most important thing that should always be considered. Given that the processes that occur within a three-dimensional graph is not a simple process, further errors in the determination or selection of a three-dimensional algorithm to perform a specific job can result in swelling of the use of processing time or even cause the error output of three-dimensional graphics that are not expected. Understanding of basic concepts and algorithms used in the techniques of three-dimensional graphics processing plays a very important as a guide to choosing the appropriate algorithm in a specific three-dimensional process. Share kinds of algorithms have been developed and therefore the selection of an appropriate algorithm for a particular issue a great effect on the performance of a system of three- dimensional graphics. It is expected that with the writing of this it can be helpful in determining an algorithm for a particular process, and it is possible to develop other algorithms are more effective and efficient.

Abstract

AbstractScientific writing is about how to work on WLAN wireless USBbased access point between two servers and client computers. The problems thatWireless USB appears is designed to communicate with the network withoutcable, so that between computer servers and client computers can be directlyconnected.Using USB as a media receiver wireless network withoutcable. So that Wireless USB can tekoneksi anywhere that has access areaWLAN networks. Wireless USB has a functioning electronic circuitsas a transmitter (receiver and transmitter) that capture the signals givenby the access point .. So that in building a wireless network requireddevices and USB wireless access point as a communication medium between the HostController.Bibliography: (Ix + 63 p.) (2002 - 2007)

Abstract

Computer network technology and the internet today has become one of the important needs in life activities. Every day continues to grow, the development of a busy discussed and discussed today is the technology that lead to Next Generation Network (NGN) which will most likely be the technology platform on Internet Protocol (IP), one of the technology into use is a softswitch or known by the name Voice over Internet Protocol (VoIP). VoIP Technology able to communicate using voice infrastructure like the Internet using regular phone at no cost to regular phone. In addition, VoIP technology uses voice compression technology to provide efficiency and utilization bandwitdth, so that data communication is not disrupted.
