Abstract

The industrial revolution has significantly increased greenhouse gas emissions, leading to global warming and climate change, which burdens producers worldwide. In Indonesia, PT United Tractors Tbk, as a major player in the heavy equipment industry, faces challenges in the environmental reporting process due to the use of separate data collection methods between digital and non-digital (manual paper- based), which results in a lack of proper integration among aspects, making it impossible for environmental reporting to be done in real- time and causing difficulties in tracking the reporting data. This research aims to design an intuitive user interface (UI) and a seamless, satisfying user experience (UX) for a mobile-based environmental reporting application using the User-Centered Design (UCD) method, focusing on integrating all aspects of environmental reporting —including water, hazardous waste, non hazardous waste, and air—into a practical mobile platform for the company's environmental staff. The System Usability Scale (SUS) method was then employed to evaluate user satisfaction and acceptance of the developed application. The SUS results from 12 prospective users among the company's environmental staff showed an average score of 89.4, with the lowest score being 82.5 and the highest score being 100, indicating an excellent score and demonstrating that the UI/UX design is highly satisfactory and well-received by users.

Abstract

E-learning is learning with information technology in providing material and interaction between teachers and students. In the application of e-learning must have easy access for students and teachers because it will affect teaching and learning activities. However, in the application of e-learning, there are still difficulties felt by students as has been implemented in MTsN 16 Jakarta. Based on questionnaires and interviews conducted at the beginning of the study which was attended by 30 respondents obtained results where the e-learning used had difficulty in finding assignment forms, task deadlines, and discussion forums by obtaining an SUS score of 42.9. In this case, a redesign is needed to solve the problems perceived by the user. This research uses user-centered design (UCD) in design development because UCD focuses on users to meet user needs and can improve the ease of accessing e-learning based on user needs, in addition to the development of redesign e-learning will take references based on users and e-learning that has been used before. The e-learning redesign prototype will be tested using the System Usability Scale (SUS) followed by 61 respondents. From the test results using SUS got a result of 80,82 which is included in the good and acceptable category. This research also shows that redesigning e-learning using UCD can facilitate access and learning activities carried out by students

Abstract

Aerial Photogrammetry is one of the products from the fields of geography in taking the object, area, or phenomenon on the surface of the earth. Using kamera with a photographic recording process and by the help of a detector in the form of film. In the application, required proper technique in merging images of aerial photographs in order to gain a broader perspective. In this final project, stitching method used in order to merging the images. Image stitching is a method for combining multiple images with overlapping fields of view to produce a panoramic image or picture, the image has a wider viewing angle. Image stitching takes some of the features of the image as a reference in merging overlapping areas, it's named FAST corner detector. The results suggest that the FAST corner detector with a threshold n = 9 appropriate if used in image stitching process that resulted in three classes based on the panoramic image of the cross correlation results, which is the upper class (cc>0.9) on the image with stitching horizontal, diagonal and vertical, the medium class (0.8<cc<0.9) on the image with stitching involves rotation and the lower class (cc <0.8) on a stitched image with scale.
