SMAN 1 Sumbawa is a school that provides information to students through a website-based information system to facilitate school administration services. Considering that the Website can be accessed widely, it is necessary to pay attention to the security of the Website. One of them is by using the Vulnerability Assessment method. The Vulnerability Assessment method is a method for conducting vulnerability testing on a website or application that has the potential to enter an attack which consists of several stages such as Network Discovering, Vulnerability Scanning, and Result Analysis. This stage aims to identify security holes on the SMAN 1 Sumbawa website. The tests that have been carried out have identified four levels of vulnerability, namely high, medium, low, and informational on the SMAN 1 Sumbawa website. The hight vulnerability level obtained is SQL Injection. The SQL Injection vulnerability makes it easy for attackers to access the entire database. The results of the tests that have been carried out show that the SMAN 1 Sumbawa Website has many vulnerabilities or Vulnerability that the SMAN 1 Sumbawa Website is still in an unsafe state.
Information and communication at this time absolutely become a basic need that must be met. Even for some people, they need information whenever and wherever they are. And the technology that can fulfill this need is wireless technology. In an interview with Mr. yudi alfiandi as the Information Technology unit. Whereas R S H.L Manambai Abdulkadir often experienced disturbances such as flooding and illegal access. Therefore R S H.L Manambai Abdulkadir needs a network security system analysis in order to ensure that R S H.L Manambai Abdulkadir is good in terms of network security systems, especially wireless networks. Therefore, a standard tool is needed in analysis using the Penetration Testing method. The results of the tests that have been carried out, that access point 1 has a password that is very easy to guess and vulnerable to attacks, so it needs better handling and uses a passphrase.
Bandwidth struggles and non-optimal internet networks can result in connection problems, such as slow connections and allowing users not to connect to the internet. therefore it is necessary to optimize computer networks to be able to maximize service to users, both used to find information, download and upload data. This study uses the Queue Tree and PCQ methods which aim to optimize computer networks at SMKN 1 Sumbawa Besar and improve the quality of computer networks in terms of delay, jitter, throughput, and packet loss. This type of research is qualitative and quantitative research. Research methods include data collection (observation, interviews, literature study), analysis, design, implementation, and testing. Based on the test results after using the Queue Tree and PCQ methods, the average values of delay, jitter, throughput, and packet loss are more optimal than before applying the Queue Tree and PCQ methods. The delay measurement in data rate before applying the Queue Tree and PCQ methods is 1414925 m/s and after applying the Queue Tree and PCQ average delay is 3,165 ms. Test Jitter on the data rate before applying Queue Tree and PCQ methods is 1414957 ms and after applying the queue tree and PCQ jitter is 3,164 ms, Throughput on data rates before applying the Queue Tree and PCQ methods is 5043 kbps and after applying the queue tree and PCQ throughput is 2486 kbps, Test packet loss on data rates before applying the Queue Tree and PCQ methods is 7,911% and after applying the queue tree and PCQ methods is 0,030%.
