Abstract

Microcontroller-8031 is a minimum system that can combine the input and output adigital signal that can be used for the control of an application tool, primarily locatedin industrial. By using an 8031 microcontroller-system device can be controlledsimultaneously / together as well as reliable, because the microcontroller-8031 has aprivilege in terms of hardware.With its features, the microcontroller-8031 can be very useful for the development oftechnology, especially in digital control systems are very efficient and effective.Microcontroller system is a control center of the overall work system.Microcontroller for digital circuits are used as a store counter or control commandsfrom the calculations that will be shown at 7-segment display.Among the advantages to use microcontroller-8031 in this series is due to thepresence of all devices are required, so no longer need a computer and interface, sono longer need a computer and an interface so that the circuit becomes moreeconomical and efficient. whereas in data processing within the systemmicrocontroller, 8031 assembly language is used.

Abstract

By leveraging existing technology and at this point, these tools can we design a smaller and simpler, without reducing the reliability of these tools. In the design of this tool there are some weaknesses, namely in the operation of the tool is basically due to the quality factor of the quality of each component is different from the standardization of a component.

Abstract

Combination "Design Series Basic Input With PPI 8255 Intermediary Language Using C", a series composed of PCs, interface 8255, and a series of basic input modules that are interconnected with one another. 8255 PPI serves to mediate between the computer with the Combination the basic inputs. Combination of this function to enter data in the form of binary numbers and then output the results can be viewed on a computer screen in the form of decimals. For data processing in this circuit using the language C.

Abstract

Card PPI series serves as a liaison (interface) between a PC with equipment beyond the PC. This circuit is used as a comparator IC and IC 74LS688 8255 as the output data from microcomputer. to activate this card PPI use of assembly language programs that previously have done port initialization. IC 8255 will be active when the comparator is active (low), determine which ports are used is from the address bus A0 and A1. PPI Card With this we can make a circuit or a module outside of a PC (Personal Computer) that can be treated by using a computer program. like, moving the series of LED lights, moving the DC motor circuit.

Abstract

In all cases, the process of choosing what type of system and network to the appropriate network operating system relies heavily on an understanding of running a business firm (in terms of managing data and information into something meaningful). Hence thing to note is studied process data and information flow within an existing business in a way to analyze and evaluate as precisely as possible. Emphasized here that the selected network must support and reflect the ways data / information flow or process in the conduct of company business. Reviewing and analyzing the data stream back to processed into useful information, and efforts to improve management processes, and visualize network support for the improvement company.

Abstract

Overclock is an activity "forcing", "spur", "optimize" a hardware such as processors, memory, display adapters, etc. for work outside the standard specifications limit its maker, because every manufacturer of hardware is always giving tolerance of labor value hardware products.That way, the technique is done properly overclock and neat, a discovery that would be quite beneficial for computer users as a free upgrade solution.

Abstract

In this thesis, we presented the design of measuring devices, which may be used to measure the effective voltage value of an electrical signal.operation of this measuring instrument used for measuring the effective price of the wavesthat shaped not sequentially, either periodically or non periodic.Designrestricted to the use of measurement of stress waves within the audio frequency region.The main circuit consists of voltage sensor, which at the same time as devidervoltage, the effective price of a modifier of voltage (current) direction, and the last is a digital voltmeter. The output from the sensor circuit signal voltage is still a form similar to the original signal is measured, but the amplitude is different, tailored to local measurements. Modifiers effective price will count valueto floweffective unidirectional signal output from the sensor circuit. The output of this converter circuit becomes the input of digital voltmeter, which is then displayed by the viewer seven sections (seven segment).

Abstract

Communication via the power cord (Power Line Communication), is something the local loop network technology, known as a technology "Las Mile", which utilizes telecommunications network Infrastructure. In Indonesia it is still common. however, the parties involved in this case the PLN (State Electricity Company) has been disseminating the use of electrical cable as a medium of computer networks, eg for accessing the Internet and collaborate antarkomputer very quickly. PLC technology has many advantages, diataranya terms of the cost of using the Internet with modern furniture is very cheap because the PLC is used that is fixed tariff rate, where in so we can pay to use the internet service this month both internet usage and long distance telephone, modem berbedadengan ordinary all use electricity and telephone tariffs, so that both of them became swollen fees (expensive), another advantage is speed of data transfer where the data access rate of about 3.2 up to 5.6 megabits per second. This is the same value as in the use of cellular networks for personal and internet access was very adequate. meaning for the transfers amounted to 50 Megabytes of data, only takes about one minute, another advantage that is flexible, and access without cable, so that using reknologi PLC can be made as a means to accelerate the improvement of the quality of human resources and their economic growth in Indonesia in general.

Abstract

Network-based computer by using the soundcard packet radio modem has many features compared to conventional networks, packet radio networks can use the soundcard as a radio modem, thus reducing costs in their manufacture, and soundcards that we use for the radio modem can we change the configuration so that it can reduce costs in the production network packet radio.
