Abstract

Attendance is an important thing in government agencies. By having a good attendance system, it can help in controlling the work completion process in order to get optimal results and in accordance with the predetermined goals. This research aims to develop a Website-Based Attendance Application that can optimize employee attendance management at the Binjai City Bappeda office, and can also ensure that employee attendance complies with applicable rules and policies. This research uses the waterfall method to design and present a website-based employee attendance application for the Binjai City Bappeda office. The results of system testing are carried out using the black box testing method by observing the execution results through test data and verifying that the Software function really meets the criteria or is functioning. It can be concluded that the existence of this Website-Based Application system can help employees manage their absence time effectively.

Abstract

Photos of heroes are one of the important images in history. Today's hero photos have poor image quality because the camera technology that existed in the past was still simple. Due to technological limitations at that time, the current hero photos are still of low quality with the dominant color being gray. This condition results in the information contained sometimes not being received properly. To overcome this problem, it is necessary to improve the image quality of hero photos which are still of low quality. Image quality improvement is one of the image processing operations which aims to perfect the image by manipulating image parameters. This operation is often applied to images that have poor quality so that the quality can be improved. In this research, we will apply image enhancement operations or improve the image quality of hero photos so that the quality can increase. There are many methods that can be used to enhance images, one of which is histogram equalization which has been widely used to enhance images, especially greyscale images. This method is usually done on images using the Matlab application because of its simple use. This research produces new images with better quality than previous images
