Abstract

This paper presents a visual tracking system to support the movement of the robot head for detecting the existence of objects. Object identification and object position estimation were conducted using image-based processing. The movement of the robot head was in four directions namely  to the right, left, top, and bottom of the robot head. Based on the distance of the object, it shifted the object to many points to assess the accuracy of the process of tracking the object. The targeted objects are detected through several processes, namely normalization of RGB images, thresholding, and object marking. The process of tracking the object conducted by the robot head varied in 40 various object points with high accuracy. The further the object’s distance to the robot, the smaller the corner of the movement of the robot produced compared to the movement of the robot head to track an object that was closer even though with the same distance stimulant shift object. However, for the distance and the shift of the same object, the level of accuracy showed almost the same results. The results showed the movement of the robot head to track the object under the head of the robot produced the movement with a larger angular error compared to the movement of the robot head in another direction even though with the stimulant distance of the same object position and the distance shift of the same object.

Abstract

This study presents Augmented Reality (AR) implementation for learning geometry mathematics with a cultural approach in junior high schools. The research method used was ADDIE (analysis, design, development, implementation, and evaluation) by limiting it to (1) exploration analysis, (2) design, (3) development, and (4) implementation. Applying the AR concept to the mathematics learning method with a cultural approach is hoped to create an interesting and fun mathematics learning atmosphere. This is because the application of AR concepts in mathematics learning can help students towards abstract mathematical concepts with the help of 3D objects and improvisation of appropriate sounds and images. The research results are an AR application prototype for learning geometric mathematics with a cultural approach in junior high schools, which can be used for geometry material in junior high schools for both classroom and online learning.

Abstract

Moderate intellectual disability requires a specific behavioral approach of learning Activity of Daily Living (ADL). This study aims to develop an appropriate and effective ADL module for moderate category intellectual disabilities in a special program instruction based on behavioral approaches. This research is a Research and Development (RD) using the Dick and Carey development model. The Dick and Carey development model consists of 10 steps of development, namely identifying needs in setting goals, analyzing learning, analyzing learners and context, developing learning objectives, developing assessment instruments, developing learning strategies, developing and selecting learning materials, designing and implementing formative evaluations, improving learning, designing and conducting the summative assessment. The module was implemented in the Special School of PGRI Sentolo and the Special School of Ma'arif Bantul through individual trials involving one subject, a small group trial involving six subjects, and a field test involving 15 subjects. Data collection was carried out using interviews, observations, questionnaires, and performance tests. The results of the study are that the ADL module is feasible and effective to use. The module was designed according to a behavioral approach, including the objectives were arranged from simple to complex, the presentation of the material was based on task analysis, verbal positive reinforcement was presented by the flap lift, and rewards are provided as star stickers available in the module.
