In determining the best employees in the company can spur employee enthusiasm in working, because the company will provide incentives or bonuses for these employees. However, in determining the best employee, several parameters and criteria are needed so that the assessment is carried out on target. The improved performance of employees will certainly have a direct impact on the quality of company services. Employee performance appraisal is carried out by a human resort management (HRD) director and the assessment consists of a number of criteria. The assessment will be difficult if done manually considering that each assessor has their own preferences in conducting the assessment. To overcome this we need a computer system that helps decision making in determining the best employees, namely a decision support system (SPK) for determining the best employees in the company. The decision support system developed in this study uses the Fuzzy Analitycal Hirarcy Process (AHP) method to assist decision making. Fuzzy AHP method is used for decision making in each assessor. Based on the final results of the best employee determination system in the form of ranking the final value of each employee. The highest value is used as a recommendation as the best employee in the company.

The access point configuration used for wireless connections in Amikom is manually configured one by one. Each access point is configured using several SSIDs based on the department that will connect to the access point. The use of multiple SSIDs in one access point turned out to have a bad effect on network performance, from the test results, for access points configured with more than four SSIDs, the connection was very slow. The security standard used for connection from the user to the access point is WPA Personal, where WPA Personal can be said to be very weak because for each SSID it will use the same user and password for all users, this is often the cause of access leaks. To improve network security and make it easier for the author to do maintenance on the network, the author tries to use the IEEE 802.1X protocol that is connected with RADIUS and access point controllers so that the configuration and maintenance of wireless networks can be centralized, user administration and passwords can also be centralized server radius and also a better level of security using WPA Enterprise security in the IEEE 802.1X protocol.
