The purpose of this research is to provide good Quality of Service for all internet users in a network by managing bandwidth with Peer Connection Queue (PCQ) method using Queue Tree. The background of this research is because there is often an uneven bandwidth sharing in every user in a network that results in one user can access the internet faster and another user accesses the internet more slowly than other users. By applying the Peer Connection Queue (PCQ) method using Queue Tree, every user who accesses the internet will get an even bandwidth allocation. Testing using Mikrotik RouterBoard with multiple computers connected via wired and some devices connected over a wireless network. The results showed that bandwidth management with PCQ method using Queue Tree gives better results than without using PCQ because by using PCQ all users who are members of one network get equal bandwidth allocation between one and the other so that users feel fair. Which means the Quality of Service provided by the network provider has been very good

Plant growth depends on the level of soil fertility and also the availability of water content in the soil. To maintain plant growth, a way is needed so that the process of watering plants can be switched from the manual watering method to a more modern one by utilizing information technology, the internet of things. This research takes the example of chili plants as a plant that will be an example of the application of the internet of things, especially the process of watering plants according to the water requirements needed by chili plants. Systems (tools & software) that allow the process of watering plants to be carried out automatically were developed with the aim of making work that is usually done by humans easier, especially in watering plants. With the application of the internet of thought in the process of watering the plants, it is expected that the amount of water needed in the process of watering the plants will be in accordance with the needs of the plants. This study designed an internet of things-based tool that would be able to water plants automatically using a soil moisture sensor at soil moisture content YL-69 and controlled by nodemcu and would receive instructions from an Android device that could provide information on soil moisture values according to soil pH. suitable for chili plants. This research has produced an internet-based plant watering system of things that has automated the process of watering plants according to the needs of these plants.

The purpose of this research is to analyze and design an IP VPN-based Wide Area Network (WAN) at PT. Autocomp Systems Indonesia to facilitate employees in accessing a centralized information system quickly, stably and securely. The company currently uses a Leased Line-based WAN network, but there are many disadvantages such as high costs and low bandwidth capacity. so the authors try to solve this problem. The methodology used in this research is NDLC (Network Development Life Cycle). The NDLC method consists of Analysis, Design, Simulation Prototyping, Implementation, Monitoring and Management. To design this network the author uses GNS3 simulation software (Graphical Network Simulator-3).The conclusion obtained from this study is that IP VPN-based WAN networks can reduce costs and provide higher network speeds than Leased Line-based WAN networks.
