Abstract

Human resources in a company organization are very important to support the progress and quality of the company in achieving its goals. Human resources are a determining factor for success in achieving a goal. Therefore, a way to improve employee performance is needed, namely by evaluating employee performance. CV. Karya Indah Motor is required to continue to strive to provide the best service to ensure quality, reliability, efficiency and satisfaction to users. To do all of that, the company must have a mechanic whose job is to serve customers who come to perform regular service. Currently there is an assessment process or selection of the best mechanic, but it tends to be subjective based on proximity to his superiors so that it will cause jealousy and eventually mechanics are less motivated to work. Therefore, an appropriate method is needed to calculate the weighting of the criteria used to produce a decision to determine the best mechanic. Analytical Hierarchy Process method can assist in determining the priority of several criteria by conducting a pairwise comparison analysis of each criterion. The criteria determined include discipline, attendance, SOP standards, loyalty, and responsibility. With a decision support system that provides information, modeling and data manipulation that is used to help decision makers in semi-structured situations.

Abstract

The advancement of the internet impacts the flow of information circulating among internet users, which increases yearly. Telkom University has a TULT building that provides internet access services to all internet users in that building. However, the internet service in that building still needs to be improved as internet users still experience internet problems such as sudden disconnection, slow connection, and unstable connection. Therefore, bandwidth management is needed to improve the quality of internet services in the building. There are several methods to perform bandwidth management, but this study uses Simple Queue and Queue Tree methods. The selection of the Simple Queue and Queue Tree methods in this study is due to the difference in configuration between the two. Bandwidth management simulation uses 4 Mikrotik routers and six laptops as clients. The simulation is conducted for 1 hour via video streaming and online meetings with each client. During the simulation, traffic data is also captured using the Wireshark application. Then, from that Wireshark capture, Throughput, Packet Loss, Delay, and Jitter from the Simple Queue and Queue Tree methods, are analyzed. This research concludes that using the Queue Tree method is more appropriate because it has a packet loss value below 1% with the internet network characteristics of the TULT building, which has a packet loss value above 7.80%. Besides that, the working method of the Queue Tree will be beneficial when the TULT building internet network is experiencing peak traffic.

Abstract

Problems related to the use of an object of Flask for various environments are often caused by application designs that are less effective and efficient. An object of Flask is used to run a Flask application based on the states or application environments. Each state or environment has different configuration requirements. The factory method design pattern solves the design problem by separating functions that return an object of Flask based on another object of the configuration class. The implementation of the factory method design pattern will be realized in a dashboard website. It will be used on the backend so that there will be a unit test code to prove the app can be run in a different state or environment
