Abstract

The idea of e-mail brings this world into the revolution in digital information. Today, e-mail is a communication media which is very popular. In order to send and receive e-mail, it needs a server which provide email service. This application usually calls Mail Transfer Agent (MTA). One of MTA that usually used is Zimbra. This research tries to implement and optimize the mail server Zimbra which install in operating system Centos 5.0. Testing of optimization is conducted by setting account in administration and makes a communication with e-mail.Keyword(s) : mail server, MTA, operating system, ZimbraSubject Description : H.4.Information System Applications | H.4.3.

Abstract

This research aims to analyze the influence of traffic in relation to data transmission which arrived from severalnodes by applying 802.11 protocol with CSMA/CA method. The simulation was performed using MATLAB with 5nodes and 16 data packets with simulation time of 600 ms. The result of this experiment shows that theutilization of CSMA/CA as protocol provides better results than CSMA. Thenumber of transmitted packets improve twice as much as when using CSMA method.Keyword(s): Protocol 802.11, CSMA/CA, RTS, CTS, ACK.Subject Description : C.2.

Abstract

Rapid development of the City of Jakarta were followed by increased population. This phenomenon have an effect of creating more unfortunate people. As a consequence, the Local Government of Jakarta requires to build more social and public facilities. Therefore, informaton system becomes very important to provide information to public regarding the location of the facilities. The system is based-on Geographic Information System (GIS). This system assists the Local Government in planning the city development as well as facilitate user for searching social and public facilities.Keyword(s): Mapping, Social facility, Public facility, Geographic information system.Subject Description : H.

Abstract

Nowadays, the development of programming language given rise to the creation of new software which includes application, operating system and programming language. Programming language Gentee is one of the new programming language where its features and structures similar to C language.Gentee was developed based-on C library and has a procedural characteristics. This research was conducted to compare between C language and Gentee. Gentee may be used for the development of standard application as well as web-based application. In this paper, application of factorial computation was developed as a target application for the comparison.Keyword(s): Gentee language, C language, Procedural, Application, Factorial.Subject Description : D.2.Software Engineering | D.2.8.Metrics | Performance Measures

Abstract

Along with the advancement of Internet technology, currently launched Broadband Wireless Access (BWA). This technology is very popular in residencial area. In this research, implementation of BWA in Tanjung Mas Raya Estate will be explained. The concept used in this case study is RT/RW Net, which is implemented using wireless technology in the frequency of 3.3 GHz. This system will be used as communication forum between houses, such as information exchange, expressing opinion, online polling via email, chat and web portal. In the future, the system can also be used for Voice Over IP (VoIP) so that voice communication among houses will be free of charge.Keyword(s): BWA, Network, RT/RW NetSubject Description : C.2.Computer Communication Networks | C.2.0.General | Data Communications

Abstract

In the information era at this time all humankind in each aspect of his life expect a fast and exact service both in the healthy situation and the situation to be sick. Likewise his matter with that is hop for by all the elements of the framer of the system in the Pancoranmas community health centre, the patient 's satisfaction is not enough only well not him the community health centre, professional him the doctor along with medical him, but also depend from fast and to be precise the information service that is need by the patient. By using aids of the system plan, then is develop by an information system so as facilitat in the matter kept, modified, process and access the data in accordance with the requirement, from this system it is hop time that is us to access the data like the patient 's data, medicine, the story of the health of the patient could be more fast, efficient and safe in his storage and accurate, with the availability of quality information and the good communications network interdepartmental will increase the productivity of his officials, this plan of the information system if being us is the opportunity for the community health centre to increase the service and professionalism.Keyword(s) : information system, puskesmas, spiral, water-fallSubject description: K.6.Management of Computing and Information | K.6.3.

Abstract

Nowadays, handwriting recognition has been widely used for analyzing signature, reading address as well aschanging text to hypertext. Common steps in handwriting recognition system consist of pre-processing,segmentation, feature extraction, classification and post-processing. This research describes segmentationmethods for handwriting character which acquired using online device. Characters used in this research are 19latin alphabets. In the first step, pre-processing is taken place by removing noise manually. The next step iscalculating the speed of writing. The acquired speed value is further used to calculate acceleration by applyinglow-passfilter. As shown in the figure, it is found that there are many peak change has been identified so thatlow-pass filter is also used to reduce the number of segment. Too many segments may increase the difficulties ofthe next process. This research employs 4 segmentation methods, such as Positive Negative Acceleration,Positive Positive Acceleration, Negative Positive Acceleration and Minimum Speed. From the experiments, it isidentified that by applying minimum speed, character segmentation can be perform quite wellKeyword(s): Segmentation, Character, Speed, Acceleration, Low-pass Filter.Subject Description: I.4 Image Processing and Computer Vision | I.4.6 Segmentation | Edge and featuredetection
