Abstract

Reading is an activity person to obtain information from something written. Reading involves recognition of the symbol and the letters that make a language. But there are some people who are lazy to read text in English language which is not a language that is used everyday by Indonesian people. In addition to reading, there are also the most common activities to obtain information that is heard. Hear is a way to gain an understanding of the meaning of the information in the form or sound using auditory senses. Reading activities contributed 10% ability for know information, with listening, knowing information can reach 30%. With conditions like this, then it needs an alternative media that can help treat the condition. The alternative media that can be made is text to speech fo r read text in Indonesia language and English language, for detection language using Ari Borneo Algorithm. These systems are made using Delphi 7 programming language, MBROLA Tools as Indonesia-speaking sound generators and Microsoft Speech API as English sound generator. Through this system, userscan absorb information from listening to the reading o f text by both systems.

Abstract

Along with the times, the computer network has undergone many changes from time to time. Eventually, internet network is known. To test the reachability of a host on an IP address (internet protocol) network and to measure the round-trip time for messages sent from the host to the destination, computer needs to perform ping process. Ping operates by sending ICMP (Internet Control Message Protocol) echo request packets to the target host and waiting for an ICMP response. internet connection lane determination automation uses three providers done by comparing the smallest average value of the result of the ping. The test results are printed in the form of a statistical summary of the response packets received, including the minimum, maximum and average round-trip time. The signal strength is not directly proportional to the value of average, because the signal strength is affected by the report the data RSCP, throughput and quality of services covering CSSR (Call Setup Success Ratio), CCSR (Call Completion Success Ratio), DCR (Dropped Call Ratio) and BCR (Blocked Call Ratio) which can be used to optimize the network.

Abstract

Wireless networks / hostspot using wave or signal transmission media. Waves or signals emitted from a device called an access point having a particular frequency. Signal beam is formed a circular pattern in which the antenna from the access point to the source signal. In a wireless network signal is captured and used a computer to be able to communicate with each other. PING technique is a method to double check the connection by sending data packets from the sending computer to the destination computer. This process can be seen from the travel time required to transmit data packets. So there is some problems how to convert time obtained from the PING into the distance. Algorithm Jawa can be used to convert units of time-based PING the wireless LAN / hostspot into the distance. Basically, two computers that are in a wireless LAN / hostspot will form a triangular pattern. This pattern will be used algorithm jawa to determine the distance between two computers within the wireless LAN / hostspot by utilizing modifications pythagorean theorem for isosceles triangular pattern and the large angle of 400.
