Abstract

Pothole Detection System on Pedesterian using Image Processing Techniques. The pedestrian areas in Indonesia are still far from optimal in facilitating the users or the pedestrians. Potholed pedestrian areas are found in many parts of the street. This issue can harm pedestrians, especially blind people. For this reason, research has been carried out to create a system that can detect and estimate hole distances by processing images using mono cameras that can help blind people. The methods used to detect holes are the Threshold + Blob Analysis method and the HSV method. The obtained results indicate the level of accuracy of hole detection using the Threshold + Blob Analysis method is better than the HSV method. The average accuracy level of Threshold + Blob Analysis is 88.91%, while for the HSV method is 86.82%.

Abstract

This article examines the effectiveness of the Jigsaw learning model in improving the reading skills of elementary school students in the Indonesian language subject, based on a review of 20 related research journals. It was found that the Jigsaw method can enhance students' ability to comprehend texts, expand their vocabulary, and encourage active participation and collaboration in the classroom. However, its implementation faces challenges, such as the heterogeneity of students' abilities, which requires good classroom management to ensure that every student is engaged and benefits maximally. Another challenge is the need for thorough preparation by teachers in task distribution, group organization, and strategies to facilitate discussions. Supporting studies indicate that Jigsaw can improve students' overall academic skills, including their social and emotional aspects. This article suggests that teachers should be more flexible in designing learning groups that suit students' characteristics and create an inclusive and collaborative classroom atmosphere. Overall, despite the challenges, the Jigsaw method proves effective in developing students' reading skills, as long as it is implemented with proper management and attention to students' diverse abilities.
