Abstract

Network management is the ability to monitor, control and planning a computer network and system components. Monitoring the network is part of network management. Simple Network Management Protocol (SNMP) is an application protocol on TCP / IP network that can be used for management and monitoring of computer network system. An application built with web-based will be able to provide advantages in ease of access, has a display in the form of a Graphical User Interface (GUI) to the administrator to read the conditions of a network of value provided by SNMP.The purpose of this study was to find a web-based monitoring system can be implemented using SNMP, as well as to determine the completion of the disruption of the network. From the research results can be shown that the monitoring system of web-based has been successfully implemented using the SNMP protocol as a data collection monitoring and database Round Robin (RRDtool) for the analysis of monitoring data and displays the data results of monitoring in the form of graphs and data obtained in the event of a network interruption enough accurate and sufficient information about the complete disruption.Keyword: network management,Simple Network Management Protocol(SNMP), website

Abstract

Malnutrition is one of the health problems that quite often among toddlers in Indonesia. Trace data from the WHO, the number of infants who had died from malnutrition in Indonesia in 2012 was 29 out of 1000 births. Caring parents and village officials (in this case the officer Public Health Service Center - HEALTH) to monitor the nutritional indispensable. Research conducted to try to perform a grouping of 50 children in the village of Karang Songo into 5 clusters nutritional status. Grouping nutritional status of children in the village of Songo Flower using the K-Means method is done through several stages, namely: the determination of business objectives, data collection 50 children in the village of Songo coral, grouping balitake nutritional status in five clusters, namely cluster 1 - malnutrition; cluster 2 - malnutrition; cluster 3 - good nutrition; cluster 4 - nutrition; Cluster 5 - obesity, cluster calculations using SPSS software, analysis of the output data, grouping nutritional status of children using tables Growth Chart, and the latter tested by comparing the results of the grouping of K-means algorithm and tables Growth Chart. By comparing the results of grouping using a table Growth Chart and K-Means algorithm obtained 17 data have the same group. From this figure it can be concluded that the K-Means algorithm only has an accuracy score of 34% correct.Keywords—Data Mining , Nutritional Status , K -Means

Abstract

A software development will take time and high cost. Reverse engineering is a technique or a way to find the principles of the technology of a product by analyzing the structure, function and how the product. By studying the structure of the functions of a product, this study aims to patching into software to improve the quality of the software itself. Patching which will be tested in this method is Checksum, Obfuscation / Obfuscated Code, API Redirection, Anti-Dumping where the results of the patching will be tested quality and the measured length of the Code, the Output File Results, and the number of changes that occur so as to increase the quality of the software itself Keywords : Reverse engineering, Patching, Checksum, Obfuscation / Obfuscated Code, API Redirection method, Anti Dumping Software

Abstract

Security and confidentiality are important issues that need serious attention in the era of information technology. Cryptography is one technique for securing data and information. In cryptography, the data is disguised in such a way that even if the data can be read, it can not be understood by those who do not have the authority. Data that has not undergone encoding known as The term plaintext, and after camouflaged with an encryption method, then it will turn plaintext into ciphertext. In general, a system equipped with a password to restrict only certain parties were entitled to enter into the system. If the password can be solved or known by an unauthorized person, then the data or information that is in the system is threatened. This research aims to develop a library classical password that can be used as an attempt to realize the aspect of information security in access control, by utilizing the technology component object model (COM). From the results of tests performed can be seen that the COM libraries are packed in COM DDL can be used by a variety of programming languages fairly easily.Keywords— cryptography, component object model (COM)

Abstract

Analysis of computer networking is very important and necessary to help improve network performance. Many companies are designed their networks are not in accordance with its business goals, so the performance of the existing network of the company is not as they expected. Therefore required an analysis on existing computer network within the company, both in terms of performance as well as network design. Existing network designs are closely related to the performance of the network. In this study the parameters that exist in a computer networking such as delay, jitter, bandwidth, packet utilization, packet loss and throughput will be measured to determine the performance of the network and then these parameters are used as information to redesign the network to get better network performance and generate more structured network design according to the needs of the company. Keyword : network performance, Top-Down Network Desain, delay, jitter, bandwidth, paket loss, thoughput, network design.

Abstract

Usability comes from a usable word that generally means it can be used properly. Basic usability usability levels include: Learnability, efficiency, memorability, error and satisfaction. PDAM Tirta Musi Palembang has a website that is www.tirtamusi.com, and has not been evaluated how far the website is useful (usable), in presenting information and service satisfaction to customers. The usability method can be used to evaluate the website. In the process of website evaluation, usability testing can use the supporting application that is Techsmith Morae Recorder. Morae provides functions to assist usability practitioners in planning, testing, data analysis and reporting of results. From the results of research can be seen that the website PDAM Tirta Musi Palembang not yet meet from the level of satisfaction (satisfaction). Where necessary the addition of information menu is Telephone Information and Companys Complete Address, Service Unit Information, Site Map and Searching. Research using this usability is expected to provide an assessment for the development of the website so that it can be useful and provide satisfaction to customers.Keywords: Usability, Website, Evaluation, and Morae Recorder.
