Abstract

Family welfare empowerment (PKK) is a community organization with 10 main programs that empower women to participate in Indonesia's development. The administrative process that has not been properly systemmed causes less optimal and efficient provision of data and information. In this study, the technique of developing the PKK Management Information System applies the Rapid Application Development (RAD) method, where this method has the advantage of being short and fast. The results of the SIM PKK design can provide convenience in providing accurate, fast data for policy making and also able to improve performance and efficiency in KDP organizations.

Abstract

Information technology, especially the internet, is currently growing very rapidly, due to the increasing number of people who disseminate information through the internet. The development of the number of users of Internet information technology is currently not followed by the addition of appropriate bandwidth, so problems often arise related to the speed of access to get internet services. An easy way to save bandwidth and force authentication on information traffic is to use squid. The use of Squid can be used to increase the need to speed up information retrieval. By using the Squid application, the router can be used as a proxy server for internet web cache. At the time of installing Squid without a proxy, testing was carried out on the https://www.kompas.com url and the results of the first load on a website resulted in a load time of 36 seconds, there was no difference in bandwidth usage and time whether using a proxy server or not, but the second page load on the same site with a faster load time of 30 seconds will save bandwidth. Then the installation of Squid using a proxy was carried out, testing was carried out on the https://www.kompas.com url and the results of the first load on a website resulted in a load time of 34 seconds, there was no difference in bandwidth usage and time, whether using a proxy server or not, but on the second page load on the same site with a faster load time of 16 seconds, it will save bandwidth and be faster by using squid compared to not using squid.

Abstract

Communication is a very important part in conveying information, especially voice information or voice, can be done in various ways, one of them using the telephone. Voice over Internet Protocol (VoIP) is a means of delivering information at a very low cost compared to analog phones and can be applied to existing office equipment, such as a computer, laptop and Android smartphone without the need to buy special devices. VoIP can be implemented using the internet (like WhatsApp) or on a local network (such as LAN or WLAN) which is very suitable to be implemented in companies or offices. VoIP can be implemented in companies in areas that are not affordable by the internet, VoIP is an alternative digital telephone technology in delivering information in the form of voice. The main objective of this research is to discuss the utilization and implementation of VoIP Phone voice communication systems using Local Area Network (LAN) or Wireless Local Area Network (WLAN) as a transmission media. VoIP phone systems require 2 device models, namely devices that serve as servers with the trixbox operating system and softphone on a client computer or laptop. Keywords: VoIP, softphone, Server, Client

Abstract

This virus originated from Covid-19 or Corona Virus which has had an impact and symptoms that can kill humans with various complications of the disease they suffer. The problem that occurs is the panic of people who are reluctant to leave the house and are afraid of being exposed to the Corona Virus to carry out daily activities even to seek treatment at the hospital with symptoms that resemble the symptoms of exposure to the Corona Virus. coupled with the number of hospitals that are responsible for handling the Corona Virus which is a top priority for handling minor illnesses in general. Therefore, an expert system application for the diagnosis of Covid-19 or Corona Virus is needed. The expert system also requires a method that can operate, in this study the method used is Forward Chaining, the forward chaining method solves every symptom that appears and follows the next symptom in the same rule so that a decision tree is formed

Abstract

Analyzing the difference in performance values generated by the IPv4 protocol and the IPv6 protocol VoIP services on a WAN network using a bandwidth of 128 Kbps. Session Initiation Protocol (SIP) is one of the protocols commonly used in Voice Over Internet Protocol (VoIP) telecommunications. SIP is a signaling protocol developed by the Internet Engineering Task Force (IETF) under the label RFC3261. In a telephone call using IPv4 and IPv6 with a distance of 3 meters concluded that IPv6 is better with a bandwidth of 55.1 Kb and Packet Traffic of 140 compared to IPv4 with a result of 35.1 Kbps and Packet Traffic of 150. Computer network topology is a network arrangement in which each part is interconnected with each other through physical media such as cables and optical fiber.

Abstract

In today's technological developments, information (messages) is a basic need for society. Therefore the security of an information is very important. To secure the information required a technique that can secure the data, namely cryptography. Therefore, the author makes an application that can keep confidential information. In this application, the author uses a cryptographic method, namely the hill cipher method, where the hill cipher has two processes in encoding messages, namely encryption and description. In this encryption and description process, a matrix key is used. The matrix key used by the author is a 2x2 matrix. Making this application using the Python programming language. The result to be achieved from this research is the creation of an application that can encode confidential information (messages).
