The accuracy of facial movement in the facetracking application has the result of rotation 3D objects that different according to the distance between the face with the camera, which in this paper will be tested starting from face detection with the parameters of light intensity level, the distance of the camera with face and part on the face like eye, nose and mouth. Then test the face movement every 10cm will be do face movement starting from 30cm to 110cm. Face movement testing is done with the frontal face of the camera detected then the face will be moved to the left, right, up and down the results of the face movement will also be seen on the rotation value of 3D objects in the facetracking application where the value of the rotation of each distance of movement Different. In addition, every movement of the face to the left, right, up and down will also be measured how much distance can be obtained so that the face cannot be detected by the camera. From the analysis and testing done will get the result of the ideal distance to perform the facial movement that has a good movement accuracy.

The assessment of Learning Outcomes (LO) is a critical component of educational processes, aimed at evaluating the extent to which students meet predefined educational objectives. An outcome-based approach to LO assessment emphasizes quantifiable results over the process itself, underscoring its role in enhancing instructional quality and helping students recognize their accomplishments. This study focuses on the development of a web-based application designed to assess Learning Outcomes (LO) at Politeknik Negeri Batam. The outcome-based assessment approach implemented by the application aims to enhance objectivity and accuracy, providing clearer insights into students’ progress relative to predefined learning objectives. By emphasizing measurable results, the application supports the institution’s commitment to fostering an educational environment grounded in continuous improvement. Using the Rapid Application Development (RAD) methodology, the application was created through iterative cycles that allowed for frequent user feedback and quick adjustments. This approach ensured a user-centered design while streamlining development phases, thereby meeting functional requirements efficiently. Key phases of RAD, including Requirements Planning, User Design, and Construction, were instrumental in aligning the application’s features with the actual needs of instructors and students. By providing faculty with the tools to evaluate and track students' academic performance effectively, this application contributes significantly to enhancing the quality of education. Its integration is anticipated to become a valuable component of the institution's educational assessment framework. The implementation of this outcome-based application marks a step forward in modernizing assessment methods at Politeknik Negeri Batam. By digitizing and centralizing the evaluation of Learning Outcomes, the system reduces manual assessment time, allowing faculty to focus more on instructional strategies and student support. Future enhancements to the application could include expanding its analytics capabilities and integrating it with other institutional systems to foster a more comprehensive educational assessment framework.
