Abstract

Meeting management is a series of activities aimed at planning, organizing, implementing and evaluating a meeting or meeting to achieve certain goals. The Bureau of Government and Regional Autonomy at the Office of the Governor of North Sumatra functions as a technical institution that handles government affairs and regional autonomy under the coordination of the governor. It is not uncommon for this bureau to hold meetings every day. When holding a meeting, meeting management such as attendance lists and meeting minutes are still done manually using paper and recorded by hand and then stored in a storage room. Manual processes like this tend to be time consuming and can increase the risk of errors. Seeing this problem, the need for the process of checking information on availability and confirming the borrowing of a room to be used for meetings takes a relatively longer time so it becomes an obstacle. The aim is to design and implement an effective information management system to increase the efficiency of meeting minutes in government bureaus and regional autonomy. This system was built by modeling several UML diagrams such as use case diagrams, activity diagrams, and class diagrams. It is hoped that the Bureau of Government and Regional Autonomy at the Office of the Governor of North Sumatra can improve the quality of education which can be realized through the appropriate and efficient use of information technology.

Abstract

This study aims to evaluate the performance of high-pass and low-pass filters on high-resolution images using MATLAB software. High-pass and low-pass filters are two basic techniques in image processing that have different functions. A high-pass filter is used to accentuate details and edges in an image, while a low-pass filter is used to smooth the image and reduce noise. This research covers the application of both types of filters on various high-resolution images, as well as the analysis of filter performance based on image quality metrics such as Peak Signal-to-Noise Ratio (PSNR) and Mean Squared Error (MSE). The results show that the high-pass filter is effective in preserving edge details, but increases the noise level. In contrast, low-pass filters are effective in reducing noise, but may cause the loss of some important details in the image.
