Abstract

Automatic Trash Capacity Detection System for Real Estate, there are two parts including: transmitter unit part and receiver unit part by alternating communication. The both of parts working by wireless using Radio Frequency wave. The transmitter unit part there are Infrared Sensors module, Microcontroller module, Modulator of Frequency Shift Keying module, and Transmitter of Frequency Modulation module. While on receiver unit there are Receiver of Frequency Modulation module, Demodulator of Frequency Shift Keying Module, Microcontroller module, Interfacing module, and Personal Computer for monitoring and database view.

Abstract

Every people’s need for drinking water in fulfilling daily needs is very important to support their activities. Technology developments, a life style of people were changes rapidly. In the past time to get the ready-to-consume water they had to boil it first, but now a simply refill the gallon with water. With the change of life style of the people who consume refill water in gallon, then various drinking water refill depots emerge, however in reality the water volume is not equal in every refill. For the above reason, the design of a microcontroller-based drinking water refill automation system model. This instrument consists of two sections that are transmitter and receiver. This drinking water refill automation system instrument can operate in accordance with the desire and can perform the refilling with minimum liter volume of 1 liter meanwhile the maximum volume of 15 liters.

Abstract

It has been well known that TV 7 one of TV stations in Indonesia always provides good quality of program for its clients throughout national frameworks from its head quarter in Surabaya. Field strength antenna plays important role in this service, especially its prominent parameters like antenna gain, radiation pattern as well as its radiated powers. It has been noted from this investigation that upper antenna suits for the above purpose.
