The need for LCD projectors is very urgent, so even though they often experience shortcomings, it is impossible to continue to make purchases when needed to repair LCD projectors that require high costs such as buying a new device. Software development from the results of this study is not only beneficial for educational institutions but also for personal or specific institutions and institutions who want to conduct seminars, presentations, or other activities that involve many audiences. The advantage is that the audience will not experience problems such as when using an LCD projector, such as limited visibility, location or space, and the viewpoint of the audience on the Projector LCD / Screen. Another contribution that can be given from this research is a model of the teaching and learning process in real-time without using an LCD and only using a PC/ Laptop connected to the same LAN. It is a development of research that supports the concept of green computing because it also reduces the use of equipment LCD projector, but the usage function remains the same even more effective and interactive even without the device. Presentation model like this is the development of new models in the learning process using LAN networks but without using the internet connection and is the cross-platform model. This research can be the answer to the need for using LCD projectors that often occur in the process of education, meetings, or seminars that continue to increase every time. Also, the lack of LCD compared to the number of teaching needs in each class and the unstable electricity conditions and the low electricity ratio in East Nusa Tenggara, have resulted in frequent blackouts suddenly, so that makes the device LCD vulnerable to damage. The test results showed an increase in RTT along with the increasing number of servers conducting presentation activities. Testing on LAN networks with the same number of clients on each test shows that there was an increase of 18% and 75% in each addition to the number of servers. The best performance of Powerplan is still shown when the number of servers that present several five, with the response time of each client connected under two seconds.

Data is a very important need for an Education institute, one of them is SMK Persatuan Ummat Islam. Because data is an important asset that must be protected and protected by its security. For this reason, a media is needed that can store data that are important and valuable assets so that they are guaranteed security and maintenance. Data processing is connected to the local area network (LAN) of SMK Persatuan Ummat Islam. Storage media with good and reliable performance will certainly greatly assist agencies for data storage in improving information access services at educational institutions. It is very important to secure data from the server so that it is necessary to backup the data by adding software or hardware as a backup server computer. To be guaranteed the data backup process periodically requires an application that can backup data automatically from the server or client. NAS4Free is a server with a Linux-based operating system that is very specialized to handle data storage centrally, so that it becomes one of the very good solutions to be implemented, because by using one media as a center of data storage can reduce the risk of data loss or data damage. And can restore (restore) data if the computer is damaged. So that the hope can facilitate the work of educators and education staff in improving services in educational institutions using data backup in ensuring the security and maintenance of data which are important and valuable assets

This study presents the proposed testbed implementation for the Advanced Technology Training Center (ADTEC) Batu Pahat, one of Malaysia’s industrial training institutes. The objectives of this study are to discover the issues regarding network congestion, propose a suitable method to overcome such issues, and generate output data for the comparison of the results before and after the proposed implementation. The internet is directly connected to internet service providers (ISPs), which neither impose any rule nor filter the traffic components; all connections comply on the basis of the base effort services provided by the ISP. The congestion problem has been raised several times and the information technology (IT) department has been receiving complaints about poor and sometimes intermittent internet connection. Such issues provide some ideas for a possible solution because the end client is a human resource core business. In addition, budget constraints contribute to this problem. After a comprehensive review of related literature and discussion with experts, the implementation of quality of service through add-on rules, such as traffic policing on network traffic, was proposed. The proposed testbed also classified the traffic. Results show that the proposed testbed is stable. After the implementation of the generated solution, the IT department no longer receives any complaints, and thus fulfills the goal of having zero internet connection issues.

Web Based

Previous studies have shown that motivating students to learn about local area network (LAN) design can be difficult when presented in the traditional lecture format. To overcome this problem, a Web-based tool (“WebLan-Designer”) was developed as an aid in teaching and learning of LAN design at the introductory level. A WebLan-Designer provides a set of learning resources (tutorials, quizzes, network modeling, network design scenarios, key terms and definitions, and review questions and answers) and assists undergraduate students in learning the basics of both wired and wireless LAN design. The tool is Internet-based and can be accessed at any time so that students can study LAN design at their own pace and convenience. This flexible learning approach contributes positively to distance education and e-learning. The effectiveness of WebLan-Designer is evaluated both formally and informally; positive student and peer feedback indicates that the design and implementation of the tool has been successful and that using WebLan-Designer may have a positive impact on student learning and comprehension.

And Control

Managing the usage of Local Area Network is an important task as it helps in maintaining the productivity of the LAN There exists tools for this purpose and most of them are web interface based, they can control and monitor the usage only when connected to internet. Moreover proper usage logging and usage control based on the already set schedule is also absent. Practically, this management do not suffice the need of higher educational institutions because the areas like accountability, usage logging and control is not addressed in this approach. Both are important factor of enhancing management of LAN. This research paper proposes a tool-LABGUARD to incorporate these features. Further the tool has been implemented using .Net Technology. As a result, the usage of systems was accountable, only the authorized user could access the assigned sites with granted privileges at the retrospective time. Thus the system became more accountable and secured. It also enhanced the control of administrator on entire lab setup. It also facilitates the administrator to retrieve log details.
