This research is motivated by advances in information and digital technology, which provide opportunities for teachers and students to take advantage of the sophistication of digital technology in the learning process, but based on the facts, most teachers experience difficulties in compiling online devices. Apart from that, from the initial study, the test of mathematical problem solving abilities for some students was still low. This is in accordance with the results of the 2018 PISA and 2021 AKM which are still classified as below average, which form of evaluation is a cognitive indicator of students' mathematical problem solving abilities (Kemendikbud, 2019). One of the efforts that teachers can make to improve this ability is to design conducive learning. The results of an initial survey conducted through interviews with 28 mathematics teachers from several junior high schools in Kampar district showed that most of the teachers were not able to independently design learning tools that could facilitate students' mathematical problem solving abilities. Thus, the purpose of this research is to produce an online learning tool using a realistic mathematics education approach to facilitate students' mathematical problem-solving abilities in curved sided geometric material. The online learning tools designed are syllabus, lesson plans, worksheets and introductory learning videos.
The development model used in this study is Borg and Gall, with 8 stages, namely: (1) the research and data collection stage, the researcher conducts a needs analysis which includes analysis of learning tools, material analysis and student analysis; (2) the planning stage, namely making the basic framework of learning tools in the form of syllabus, lesson plans, worksheets, introductory learning videos; (3) the development stage of the initial form of the product, the researcher compiled the initial product design and validated and revised the product according to suggestions from the validator, (4) the initial field trial stage, at this stage the researcher gave LKPD and videos to 6 students to find out the practicality of LKPD and videos using student responses; (5) the revision stage of the trial results, at this stage the researcher adds suggestions from students and teachers when conducting small group trials; (6) In the main field trial phase, the researcher gave LKPD and videos to 30 students to find out the practicality of the device through a student response questionnaire; (7) the stage of product improvement as a result of field trials, the researcher revises the product according to the results found and the suggestions given at the product implementation stage so that the learning tools become suitable for use; (8) dissemination and implementation stages. The operational trial phase was not carried out, because the learning process at school was already in face-to-face learning conditions, which did not allow students to bring Android to school for a long duration with a large number of students.
At the research and data collection stage, it was found that online learning tools in the form of syllabi, lesson plans, worksheets, and videos used in schools were

downloaded from the internet. teachers do not make worksheets and videos that are relevant to online learning situations, teachers use worksheets from a publisher that only contain material and practice questions, students' mathematical problem solving abilities are very low, because students are not used to being faced with problem solving questions , students are more often given routine questions that only test their memory and apply simple concepts or formulas. The material taken is the shape of the curved side chamber. Students have heterogeneous abilities. The research subjects were students of class IX SMPN 2 Bangkinang kota, totaling 6 people in the initial trial and 30 students in the field trial. Development planning is carried out by researchers on syllabus, lesson plans, worksheets, and videos, then assessed by a validator. Furthermore, small-scale trials and main field trials were carried out to see the practicality of learning devices. The research instruments used in this study were: validation instruments in the form of validation sheets for syllabus, lesson plans, worksheets, and videos as well as practical instruments in the form of student and teacher response questionnaires. Data collection techniques used in this study were interviews, observations, questionnaires, and documentation, then analyzed. Researchers analyzed qualitative data by examining and describing suggestions and comments from validators and students. In the quantitative data analysis, the researcher calculated the results of the validation and response questionnaires to see the level of validity and practicality of the learning tools made. Learning devices are said to be valid and practical if the percentage is more than 70%.
The results of the validation analysis of the syllabus, lesson plans, worksheets and videos show a very valid category with a score of 89.38%, 89.07%, 90.37%, 89.75% respectively. This means that the online learning tools developed can be tested and revised according to the validator's suggestions. The results of the practicality data analysis of worksheets and videos in the initial trial showed the very practical category with scores of 91.47% and 94.97% respectively. Meanwhile, the results of the practicality of the LKPD and video data analysis in the initial field trial showed a very practical category with a score of 94.81% and 97.73% respectively, meaning that the developed LKPD and videos were practical to use.
The online learning tools that have been revised are then used as research products. The results of research on the development of online learning tools using a realistic mathematics education approach to facilitate the mathematical problem solving abilities of class IX junior high school students are valid and practical.
