The circular object tested is the moon image object, the moon image was chosen because the moon image has various moon shapes, namely the full moon, half moon and crescent moon. To detect the shape of the circular object image, several stages are carried out by starting the image segmentation process. (1) The segmentation process using the bi-level thresholding method makes the image black and white, (2) after that the image is repaired with the morphological process of the opening and closing methods. (3) For training data, the shape extraction process is carried out, namely the circular nature of the object (circularity) to determine the roundness of an object. For the testing process, the same process is also carried out as the process of obtaining circular image detection.</p> 2025-04-15T00:00:00+07:00 Copyright (c) 2025 Dadang Iskandar Mulyana, Fiktor Kurnia Tofano https://journal.lembagakita.org/jtik/article/view/3825 Expert System for Diagnosing Brain Tumors Using the Certainty Factor (CF) Method 2025-02-17T10:20:20+07:00 Veri Arinal veriarinal@yahoo.com Nuary Inaldi Simarmata nuariinaldi@gmail.com <p>The development of computer technology helps many aspects of life. One aspect of life that takes advantage of technological developments is the health sector, in order to solve problems including brain tumors. Brain Tumor Disease is the growth of abnormal cells in or around the brain in an unnatural and uncontrolled manner.

Objects that have a certain color are separated from objects that have other colors. The segmentation results can be used for further processes such as feature extraction or image classification. In this example, skin color is defined in the YCbCr color space with a Cb value between 77 and 127 and a Cr value between 133 and 173. Skin color detection is one of the initial stages in computer vision to detect things related to humans (people detection). Skin color detection can be used as a segmentation method for face recognition or recognition of other body organs. The system can be further developed for biometric systems.</p> 2025-04-16T00:00:00+07:00 Copyright (c) 2025 Dadang Iskandar Mulyana, Indah Rosmalina https://journal.lembagakita.org/jtik/article/view/3753 Sistem Pendukung Keputusan untuk Menilai Kesejahteraan Wilayah DIY dengan Metode SMART 2025-02-01T11:00:17+07:00 Muhammad Salman Al Farisy salmanfarisy2023@gmail.com Sri Winiarti sri.winiarti@tif.uad.ac.id <p>Welfare in the Special Region of Yogyakarta (DIY) is disrupted by urbanization and development inequality, which leads to poverty and other social problems.

In the medical context, AR offers significant potential, such as supporting medical training, enhancing anatomical visualization, and improving understanding of patient conditions. Cardiac anatomy training and education in the medical world still rely heavily on conventional methods including 2D diagrams, physical models, or desktop-based computer simulations, which are less interactive, inflexible, and less realistic. This research aims to develop a markerless AR application for the visualization of 3D models of the human heart to improve understanding of the heart structure in the context of heart disease treatment. The process starts with the design of a 3D model using Blender, which is then imported into Unity to be integrated with the AR Foundation, allowing the placement of the model in the real world without markers. This AR application was tested on an Android Smartphone device. The test results showed successful visualization of the heart model accurately over the human chest (physical reality). This application makes a significant contribution in medical education by offering an interactive and realistic solution. This research opens up opportunities for the application of AR in health education and medical training. Further development could include interactive features simulating the circulatory system as a whole.</p> 2025-04-27T00:00:00+07:00 Copyright (c) 2025 Aldibangun Pidekso Putro, Herman, Muhammad Kunta Biddinika, Suwanti https://journal.lembagakita.org/jtik/article/view/3593 Perancangan Sistem Informasi Perencanaan Produksi (Studi Kasus: Divisi Pangan PT.
