SMKN 5 Batam City is an educational institution located in Kavling Bukit Kamboja, Sungai Pelunggut, Kec, Sagulung, Batam City, Riau Islands. The availability of network infrastructure to be institutionalized by education will expedite the educational process including internet network services at SMKN 5 Batam City. The networks used in SMKN 5 Kota Batam are the Local Area Network (LAN) and Wireless Local Area Network (WLAN). Batam City Vocational School 5 has 82 PCs (Personal Computers) connected to the network and Access Points as access to the hotspot network, which uses an indie home ISP with a bandwidth capacity of 100Mbps and 5Mbps using an astinet ISP. Problems that occur on the internet network at SMKN 5 Kota Batam, do not yet have an allocation of bandwidth distribution for network users, causing unstable and uninterrupted network access. Therefore there must be proper bandwidth management controls, implementing bandwidth management and optimizing security authentication. So that the available bandwidth can be used fairly, by applying the queue method. And from the tests carried out, authentication of security and bandwidth management using the tree queue method, fair and even bandwidth can be used as well as the tree queue method proven to be able to use bandwidth both for downloading and downloading. uploaded.

Bandwidth problems are the most frequently encountered problems in sharing information traffic or internet access on computer networks. The factor that causes slow internet access is the large number of devices connected to the internet that are not matched by the availability of sufficient bandwidth and the lack of available bandwidth. This can be accommodated with bandwidth management methods. Bandwidth management in Mikotik uses several bandwidth sharing methods such as PCQ (Per Connection Queue), Queue Tree, and HTB (Hierchichal Token Bucket). This research uses 2 (two) bandwidth management methods, namely PCQ and Queue Tree because these methods can divide bandwidth automatically according to the number of active users and are more effective in sharing bandwidth based on Mikrotik. PCQ is a method aimed at optimizing QoS for large-scale internet networks where all queues are the same for all sub-streams, while Queue Tree is a method designed to carry out more complex queuing tasks for network traffic. The purpose of this research is to optimize the limited internet bandwidth so that it can be accessed by all users in the Local Area Network and automate the queue of devices connected to the network according to user needs so as to produce a more stable computer network performance using the network development method, namely NDLC. The results of the tests were carried out 10 times using a bandwidth of 10 Mbps which resulted in an average jitter of 1.64 ms, ping 36.8 ms, 2 Mbps throughput, and 0.1% packet loss so that the QoS of internet access was categorized as satisfactory. It is hoped that from this research the company will be able to save on internet access expenses by maximizing a small bandwidth without having to increase the existing bandwidth.

Call Capacity

With fast deployment of wireless local area networks VoIP over IEEE 802.11 wireless local area network (WLAN) is growing very fast and is providing a cost effective alternative for voice communications. WLANs were initially set up to handle bursty nonreal time type of data traffic. Therefore, the wireless access protocols initially defined are not suitable for voice traffic. Subsequently, updates in the standard have been made to provision for QoS requirements of data, especially the real time traffic of the type voice and video. Despite these updates, however, transmitting voice traffic over WLAN does not utilize the available bandwidth (BW) efficiently, and the number of simultaneous calls supported in practice is significantly lower than what the BW figures would suggest. Several modifications have been proposed to improve the call capacity, and recently isochronous coordination function (ICF) was introduced to mitigate the problem of low call capacity. The proposed modified ICF which further improves the performance in terms of the call capacity. The proposed scheme uses multiplexing and multicasting in the downlink to substantially increase the call capacity.

In Company X, the use of the internet is a demand for workers. Therefore, an internet network is very much needed in a Company X. The absence of restrictions in the use of the internet network can interfere with the security and misuse of the internet network, for this reason the arrangements in the internet network are designed. One method used is the Virtual Local Area Network (VLAN) Access Control List (ACL) method that is applied to Company X. The Vlan Access Control List method is one of the techniques for requesting an internet network access or data communication and sending a number of data packets from one computer to another. The author resets the results proving that the Vlan Access Control List with the filtering and sharing method of internet connection users can filter and identify users who have restricted access to access other users or to servers in Company X to improve data security.

The article highlights the issues related with the creation of "Smart" cabinet of physics based on microelectronics at a technical college. In fact, the "Smart" cabinet of physics is a creative space created by the students and tutors of the educational institution. Such "Smart" cabinet of physics is a "smart" educational environment that is fully automated and can be operated in three modes: "standard", "automatic", "automatic energy saving". The control of the cabinet devices is realized from a smartphone, PC and remote control. The cabinet is equipped with variety of sensors, indicators, electronic components based on Arduino UNO, MEGA, WiFi module ESP8266-12E.The indexes taken from the built-in sensors and indicators of the "Smart" cabinet are used for supplying information about the microclimate of the cabinet, for demonstrations at lectures and laboratory works in physics. The developed "Smart" cabinet of physics consists of three modules: "informational", "executive" and "demonstrational". The microcontroller ATMEL controls each module. The informational module is located in the stand "Physical basics of robotics", and the demonstrational module can be removed and used for demonstrations from the following sections: mechanics, molecular physics, electrodynamics, optics. Various sensors and components of the open-source programming platform Arduino conveniently and quickly connect to the demonstrational module (with the help of a flexible mounting board). Sensors of the "Smart" cabinet of physics give an opportunity to monitor the environment of the cabinet and outside it (temperature, humidity, pressure, illumination, level of carbon dioxide and other gases in the air),as well as to realize remote control of peripheral devices: TV, projector, lamps, sockets, curtains. All three modules connect to the wireless local area network by the topology of the "star" by means of radio communication based on the corresponding modules. The main module in it is the executive one, which has access to the INTERNET. The acquirement of the instrumental, technical, and software tools should become the main part of the system of training in a technical educational institution. The research deals with the issue of creating "Smart" cabinet of physics in a technical college.
