Abstract

Computer security is an important factor in the world of information technology. Computer network security is currently starting to be in great demand by many people. If viewed from the negative side, there will be more types of intrusion or attacks that can be carried out in a network. The aim of this research is the need for network security monitoring to find out disturbances or threats that occur in a network to minimize intrusion. And the results obtained from this research are wireshark and windump software is able to monitoring attacks on a network and software that is able to analyze in more detail is wireshark while windump for further analysis requires experts to get better results.

Abstract

The purpose of this study is to predict the rainfall in the city of Bengkulu using fuzzy logic . The boundary problem in this research is a fuzzy method used is Fuzzy Method Sugeno , testing was conducted using the software Matlab version 2013a , the data used in this study is the rainfall data from October to December 2015 were taken from the Meteorology , Climatology and Geophysics , the Center for Meteorology , Climatology and Geophysics ( BMKG ) Bengkulu. Of a series of studies conducted with reference to the design of the block diagram of the results obtained in the form of cuara on the day or the future (tomorrow) with Sugeno mentode this is to conduct experiments for 7 days with accuracy levels of over 60%. From 7 days forecasting error occurred as much as 2 days

Abstract

The aim of this research is to carry out computer network management and security at SMK Negeri 3 Seluma by using a proxy device and a sequid proxy server as an external proxy server. The research method used in this research is PPDIO method consisting of Prepare, Plan, Design, Implement, Operate and Optimize. The hardware used to configure network management is Mikrotik Roadboard, while the software used to configure network management and security is Winbox and Squid proxy server. The results of research on the implementation of network management were the formation of a network using a proxy configuration at SMKN 3 Seluma. toward network security, filtering of social media websites and websites suspected of containing viruses can be carried out according to the design and the blocking is successful.

Abstract

The computer network at SMK Negeri 06 Kaur is currently connected to the internet. However, the utilization of LAN network, especially the internet, at SMK Negeri 06 Kaur is not yet optimal, as there are still frequent network disruptions such as slow connections and a large amount of inappropriate content being accessed. This study aims to implement wireless network management based on a captive portal at SMK Negeri 06 Kaur. The study employs the Network Development Lite Cycle (NDLC) method. The implementation of captive portal-based network management is expected to improve network performance, enabling users at SMK Negeri 06 Kaur to access the network using a single username on a single device, with bandwidth allocation based on account profiles, and bandwidth management conducted via profiles connected to a simple queue. After implementing captive portal-based network management at SMK Negeri 06 Kaur, the network operates stably and effectively, with results including network speed limits and usage time limits.

Abstract

The computer network at SMAN 10 Kota Bengkulu is currently connected to the internet network, the utilization of the LAN network, especially the internet at SMAN 10 Kota Bengkulu has not been maximized, because there are still frequent network disruptions such as slow networks that cause many sites that cannot be opened when many users. This study aims to conduct web-based bandwidth management using Mikrotik at SMAN 10 Kota Bengkulu. The study used an experimental method. With the existence of Mikrotik-based network management, it is expected to smooth the network. So that the benefits of the network can be felt by users of SMAN 10 Kota Bengkulu. Bandwidth management at SMA N 04 Kota Bengkulu can be done via the web, with one user name only being able to access the network on one device, bandwidth management with this web will produce an account according to the account profile, bandwidth management is done using the web. After managing bandwidth using a Mikrotik-based web at SMAN 10 Bengkulu City, the network can run stably and well, namely with throughput results = 4.06, Average delay = 0.648, jitter = 0.018 and Packet Lost = 0%.
