Abstract

In computer-based learning process, there are communication process that goes between user; students and the sistem. Calculating perimeter of plane figures in edugame is a learning media that can help students to study and play just in the same time. This edugame is intended to help students understanding and calculating the perimeter of various plane figures way easier with the visualization. Source of the data is from primary and secondary datas of 7th Tematic Elementary School book and several journals about the theory of calculating plane figures. The application’s trial is using questionnaire with correspondents of 17 expert users that are elementary school teachers, with the average result 2.8, which is the interval score criteria as ”good”. Meanwhile, the second trial using youtube as a platform has 64 viewers and 16 comments. The average comments by users are ”This application is very useful”.

Abstract

Wasaka Museum is one of the museums in Banjarmasin City. However, the information obtained by visitors at this time is only from short writings near the object of the image, and museum guards cannot accompany visitors to get around. Furthermore, the interest of museum visitors has also decreased due to the unavailability of adequate information, minimal services, and the impact of the COVID-19 pandemic. The purpose of this research is to develop applications using Mobile Augmented Reality Technology as a means of promotion, trying to attract visitors with AR interaction treats, and the form of virtual museum tours. The methodology used is the Agile Development Method with the type of Extreme Programming (XP). Then the A/B Testing Method is used to select the user interface design. Marker-Based Tracking is a method of detecting markers so that 3D objects can appear. The conclusion is that the selected interface design is design B with a percentage of 76.9%, all the features in the application have functioned very well, and the results of the usability evaluation with a percentage of 83.33% have an Excellent predicate which means that they can be recommended for further use at the Wasaka Museum Banjarmasin in the New Normal Era.

Abstract

Image segmentation is a concept that is often used for object detection. This detection has difficulty detecting objects with backgrounds that have many colors and even have a color similar to the object being detected. This study aims to detect fish using segmentation, namely segmenting fish images using k-means clustering. The segmentation process is processed by improving the image first. The initial process is preprocessing to improve the image. Preprocessing is done twice, before segmentation using k-means and after. Preprocessing stage 1 using resize and reshape. Whereas after k-means is the contrast-limited adaptive histogram equalization. Preprocessing results are segmented using k-means clustering. The K-means concept classifies images using segments between the object and the background (using k = 8). The final step is the morphological process with open and close operations to obtain fish contours using black and white images based on grayscale images from color images. Based on the experimental results, the process can run well, with the ssim value close to 1, which means that image information does not change. Processed objects provide a clear picture of fish objects so that this k-means segmentation can help detect fish objects.

Abstract

Bisma Informatika is one of the educational institutions with Diploma education level in Denpasar that serves certification services for people who want to take certification expertise, especially those engaged in Information and Computer Technology. In order to serve optimally, Bisma Informatika applies registration which can be done by the computerized system so that the participant's data can be stored properly. After observing the use of the system at the time of participant registration, an initial conclusion can be drawn that many data fields cannot be understood by the user so they must ask the officer on duty. The data fields in question such as the choice of certification class are not clear because it does not include the implementation time, the unaccompanied participants who come from the common line (so can not include the student identification numbers), telephone numbers that cannot be entered if they exceed the capacity of the permitted number, and inconsistent field filling instructions. This shows that the usability aspect of the registration system is not being considered properly. This study evaluates the interface design and features of the Bisma Informatika certification registration system by considering the context and user needs. In an effort to find out the context and user needs, a Website Usability Evaluation (WEBUSE) questionnaire was used. The results of the WEBUSE questionnaire showed that the four categories which have a good usability level, only content, organization and readability categories are obtained.

Abstract

Transportation has become a human need today, one of which is air transportation, namely airplanes. In order for the aircraft to be used properly and comfortably, it is necessary to carry out routine maintenance, especially before flying. Problems caused by aircraft engines are sometimes small problems that do not require a high level of knowledge. To overcome this, maybe someone who has very basic knowledge of aircraft engines can do it. But sometimes these problems also require a high level of expertise regarding these components so that they require technicians or experts to repair them. Through this application, users can consult the system such as consulting with experts to find out the symptoms that occur on the plane and find solutions to the problems encountered. The expert system built using the Hill Climbing Heuristic method resulted in 72.67% when tested on respondents.
