Abstract

At the end of the day, the use of computers is intended for data processing in the form of text, images, videos, and data processing that can be carried out easily and quickly. Individual computer users and organizations in everyday life often work and store data on computers, but in reality, there are certain events where the results of work, in the form of document files on the computer, can be lost so that very important and much needed files are lost from the storage media in the computer. computer or laptop. In recovering lost files or documents, various software can be used, including Pandora Recovery, Recuva and EaseUS Data Recovery Wizard. In this study, what will be discussed is the recovery of lost data by comparing the use of the EaseUS Data Recovery Wizard and Recuva application

Abstract

In facilitating network configuration and user devices that are very often used are proxy. Because in proxy it is very easy to operate when compared to other routers. Basically, in Mikrotik, there are several features, including Capsman (Controller Access Point System Manager), which is a wireless controller feature to make it easier to centrally manage all wireless access point devices on the network. Setting up the network centrally Wireless AP Mikrotik will make it easier for operators to operate or manage the network, so that the configuration is only network speed traffic based on distance by limiting the user's distance using the Capsman facility, and monitoring more easily using the proxy and can minimize unused bandwidth so that can be used in rooms that are active in the internet network.

Abstract

SMK Negeri 9 Medan is a school located on Jl. Patriot No. 20 A, Lalang, Kec. Medan Sunggal. This school is a school that is in great demand because this school has several majors related to computers. Besides that, there are also many labs for doing computer practicum. But there are problems that occur in the computer lab network. The network often has problems when logging in to the internet and so on. For this reason, it is necessary to have adequate internet network management, a stable network connection. And internet bandwidth management is needed so that it can be shared on average among users or internet users and to improve security to make it easier to monitor its use. In this study, the focus is on hacking the network system using a proxy, namely IP configuration, network topology and network design. To build a more stable network, namely using Winbox.

Abstract

An expert system is a technology that is able to integrate medical knowledge and data processing to diagnose spinal cord diseases. With various algorithms and a carefully structured knowledge base, this expert system can identify spinal cord diseases based on the symptoms presented by the patient. The main advantage of this expert system is its ability to process data quickly and provide diagnostic recommendations consistently. The results provided from this research are an expert system for identifying spinal cord disease which was built using the Visual Basic software application system. From patient data and symptom data applied to the expert system for in spinal cord disease, it is known that the accuracy of the system for diagnosing spinal cord disease is 95% of patients.

Abstract

The attendance system is an important component in employee performance monitoring, particularly in government agencies where data accuracy and timeliness are crucial. In Batubara District Government, the conventional attendance recording process often encounters issues such as delayed input, data manipulation, and ineffective reporting. This research aims to develop a web-based attendance system to improve efficiency, accuracy, and transparency in recording employee attendance. The system was built through several stages including problem identification, literature review, data collection, system analysis, design, implementation, and testing. The resulting application allows real-time attendance recording through web-based access, featuring user authentication, attendance logging, employee data management, and automated reporting. Testing using the black box method indicated all functions operated correctly, and user feedback confirmed increased convenience and transparency. Despite challenges related to internet dependency and user adaptation, the system shows great potential in supporting modern and accountable human resource management practices in regional government.
