Coding or computer programming for children is now increasingly popular. According to various studies, children who learn coding at a very young age will benefit from learning to critically assess situations, explore different perspectives, build creative solutions, and even develop cognitive abilities. But of course the difficulty of the learning process itself is another level, and again, we need to see the fact that children nowadays are more into video games than learning makes this kind of situation become more complex. Therefore, this research was carried out which aims to design and create an Android-based coding introduction educational game called Funcode. Game development is assisted by the Construct 2 game engine and using the waterfall method from the SDLC or System Development Life Cycle. The game is in the form of a module equipped with a quiz by introducing HTML and CSS programming languages, as well as applying a little Computational Thinking material. Based on the blackbox test results, this mobile game called Funcode is successfully runs without any errors on various types of smartphones that have been tested

The Tri Dharma is three obligations that exist in higher education. The three obligations include education or teaching, research, and community service. Each component of higher education, especially the academic community, is responsible for realizing and implementing the Tri Dharma of Higher Education. Each component of the obligation in the Tri Dharma of higher education must be equipped with various physical evidence, such as documents, learning media, etc. Every University in Indonesia must have a system that can record all evidence of the implementation of the Tri Dharma. Therefore, this study aims to develop software that can help Hamzanwadi University record every progress of the three Tri Dharma components of higher education that the academic community has carried out at Hamzanwadi University, especially Lecturers. The development model used in this study is the Waterfall Development model (Requirements Analysis, Design, Development, Testing, Maintenance), but this study only describes the Design stage. The results obtained are in the form of system requirements, client needs, system architecture, flowcharts, and DFD of the designed system

The field of digital image processing, such as segmentation, has become a widely discussed topic. Segmentation aims to divide the image into parts or regions so that there is no overlap with similar characteristics, such as color, shape, texture, and intensity. The segmentation process is generally divided into three groups of segmentation, including segmentation based on classification (classification based segmentation), segmentation based on edges (edge based segmentation), and segmentation based on region (region based segmentation). Edge detection is a systematic process used to detect pixels in digital images that are not fixed or always changing their brightness level in a line or curve. The purpose of this study is to compare edge detection methods using image objects. This research was conducted using the method of Robert, Prewitt, Sobel and Canny to detect the number of white pixels in each image. The tool used in this research is Simulink Matlab, where the parameters of each algorithm will be compared. Then the total number of white pixels is calculated from each edge detection method.
