Abstract

Company X is a reputable company that has more than 1000 people employees. One of the routines that performed by company X is orientation for new employees, and there is an event that invites them to visit the factory. The location of the main office and the factory is far, so this activity lacks time efficiency. This application aims to facilitate company X in conducting new employee orientation so that the location can be seen in the virtual world. The first thing in the process of making the application is visiting the factory to determine the shape and position of the object, so that the expected results are shown to resemble its original condition. 3d object and its texture are created using Blender application that can be imported into the made application. Collision feature aims to prevent users from penetrating the objects.The position, shape and location of objects contained in the application already resemble the original plant site. The main obstacle in making this application is the creation time, so the detailed map of the plant cannot be completed. The main building, the production building and the warehouse have been made, only small objects contained in the main building have not been contained.

Abstract

In this paper aims we present tools for medical imaging applications to do skin and skull segmentation in a short time. The desired output for skin segmentation is a 3D visualization of the facial skin without any cavities or holes inside the head, while skull segmentation aims to create a 3D visualization of the skull bones. The algorithm used for skin segmentation is thresholding the image, extracting the largest connected component, and holefilling to fill the unnecessary holes. As for the skull segmentation, the process is done by removing the spines which is connected to the skull, and then extracting the largest connected component. Afterwards, mesh generation is done to produce the 3D objects from the processed images. This mesh generation process is done using the marching cubes algorithm. The testing results show that the skin and skull segmentation process will work well when there are no other objects that are connected to the skin or the skull. Skin segmentation process takes a significant amount of time, primarily caused by the holefilling process.

Abstract

Informatics department of Petra Christian University has used to practice programming for students at programming studio, especially students who take algorithms and programming course. The system is currently implemented is to provide practice programming skill according to their ability. Assessment is done by calculating the points of all questions are done correctly. Problem which occurs at about the work in programming studio is plagiarism among students’ work. Unfortunately, plagiarism checking consumes a lot of time. In one semester, each student can do about 100 questions. If the total of students taking programming course, at least 100 people, we need many people to do this work. Departing from this problem, we design and develop an application to check for plagiarism between two different answer files from the same question. The degree of similarity is calculated using combined method of Jaccard similarity coefficient and cosine similarity coefficient. This system is able to check similarities in source code files are the work of students with moderate levels of complexity.
