Abstract

Active Contour (AC) is an algorithm widely used in segmentation for developing Computer-Aided Diagnosis (CAD) systems in ultrasound imaging. Existing AC models still retain an interactive nature. This is due to the large number of parameters and coefficients that require manual tuning to achieve stability. Which can result in human error and various issues caused by the inhomogeneity of ultrasound images, such as leakage, false areas, and local minima. In this study, an automatic object segmentation method was developed to assist radiologists in an efficient diagnosis process. The proposed method is called Automatic Combinatorial Active Contour (ACAC), which combines the simplification of the global region-based CV (Chan-Vese) model and improved-GAC (Geodesic Active Contour) for local segmentation. The results of testing with 50 datasets showed an accuracy value of 98.83%, precision of 95.26%, sensitivity of 86.58%, specificity of 99.63%, similarity of 90.58%, and IoU (Intersection over Union) of 82.87%. These quantitative performance metrics demonstrate that the ACAC method is suitable for implementation in a more efficient and accurate CAD system.

Abstract

Multiple system education in SMK through On-the-job training is an effort to increase graduate quality in industrial capability. The stages of this research are data collection stage (introduction), system development stage, and evaluation phase (testing). This study, which is research and development, aims to know the feasibility and practicality of the design of web-based applications.The research was conducted at State Vocational High School (SMK Negeri) Jumantono Karanganyar particularly in majors of network computer engineering which involved 12 students of small trial group and 109 students of large-scale test.The data collection method used was observation, documentation, and questionnaire. The data obtained were then analyzed by descriptive analysis technique. The result of black box test done by using 43 items was in accordance with its function. The application expert's validation of this research was 88% meaning that it was very reasonable criteria. Meanwhile, the validation of substance was 89% meaning that it was very feasibleThe result of the usability test for the small-scale group was 68% then, it was improved and tested on a large scale that resulted 85% and was considered as practical. Thus, it can be concluded that the development of web-based On-the-job training management applications is very feasible and practical to be used On-the-job training management in SMK. It is suggested that the use of On-the-job training applications must be intensified.
