The approach used in this study is a qualitative approach with the DDR (Didactical Design Research) method which includes three stages, namely prospective analysis, metapedadidactic analysis, and retrospective analysis. The prospective analysis stage identifies the Learning Obstacles experienced by students in the cube material, including: 1) Ontogenic Obstacles, such as a lack of student interest in learning mathematics, only 50% of students in the class who like learning mathematics and lack of student mastery in prerequisite material; 2) Didactical Obstacle, namely the learning method used is still monotonous, the learning media is less varied and the teaching materials used are incomplete; 3) Epistemological Obstacle, namely students do not understand how to determine the volume of a cube, students do not understand problem solving strategies related to unit cubes. Based on the findings of LO, a Hypothetical Learning Trajectory (HLT) was compiled which was then designed a hypothetical didactic design on the concept of building&nbsp;</em><em>cube material which includes four learning objectives, namely determining the area of ​​a square, analyzing the elements of a cube, determining the volume of a cube, and completing problems related to the volume of a cube using the unit volume. The didactic design is applied by the method of snowball throwing and flashcard games. After the didactic design was implemented, the results of the LO of the final identificational test were decreased compared to the LO of the diagnostic test. The didactic design is one of the effective learning alternatives in reducing the appearance of LO in the concept of building a cube material in the 5<sup>th</sup> elementary school.</em></p> 2021-12-30T00:00:00+00:00 ##submission.copyrightStatement## PENGEMBANGAN LEMBAR KERJA SISWA (LKS) QR CODE MENGGUNAKAN KONTEKS KOTA LUBUKLINGGAU PADA MATERI BANGUN DATAR SEGIEMPAT KELAS VII SMP NEGERI 3 LUBUKLINGGAU 2022-05-24T15:42:56+00:00 Leni Lestari Aprilia Maria Luthfiana Rani Refianti <p>This study aims to produce a QR Code Student Worksheet (LKS) using a valid and practical Lubuklinggau City context, as well as potential effects. This research is a development research using a 4D model. This model is carried out by researchers consisting of 4 stages, namely: define (defining stage), design (planning stage), develop (development stage) and disseminate (dissemination stage). Data was collected using questionnaires, interviews, and tests. The subjects of this study were students of class VII.9 with a total of 32 students. From the results of the study obtained a valid learning media with a validity of 3.24 and practical with a practicality result of 96.22%; and has a potential effect on student learning outcomes where 29 students (90.62%) are included in the category of having completed, while there are 3 students (9.37%) who have not completed the Minimum Learning Completeness (KBM) determined by the school, the minimum student gets a score of 65 The potential effect of learning media is categorized as very good.</p> 2021-12-30T00:00:00+00:00 ##submission.copyrightStatement## ANALISIS KESULITAN PEMBELAJARAN MATEMATIKA MENGGUNAKAN METODE DARING DI SMP NEGERI 11 LUBUKLINGGAU 2022-05-24T15:46:35+00:00 Nanda Riyani Idul Adha Efuansyah E. <p><em>This study aims to determine the difficulties of learning mathematics using online methods atSMP Negeri 11 Lubuklinggau for the 2020/2021 academic year.

This research is a development research using a 4-D development model which consists of 4 stages, namely: define, design, develop, and desiminate stages. The dessiminate stage was not carried out due to time constraints in the study. Based on the results of research analysis by the three experts, namely: linguists, media experts, and material experts, it shows that the HOTS-based student worksheet on triangle material meets the valid criteria with an average score of 3.33 and for the one to one trial, an average score is obtained. an average of 3.39. While the results of the analysis of the student practicality sheet consisting of 6 students, it was found that the HOTS-based student worksheet on the triangle material met the very practical criteria with an average score of 3.70 and for the practicality test the teacher obtained an average score of 3.76, it means that the HOTS-based student worksheet on the triangle material meets the valid criteria and is very practical.</p> 2021-12-30T00:00:00+00:00 ##submission.copyrightStatement## PENGEMBANGAN MEDIA PEMBELAJARAN INTERAKTIF BERBASIS ADOBE FLASH MENGGUNAKAN KONTEKS RUMAH WANITA KOTA LUBUKLINGGAU DITINJAU DARI SEGI KEVALIDAN DAN KEPRAKTISAN 2022-05-24T15:36:41+00:00 Ririn Suhariani Rani Refianti Lucy Asri Purwasi <p><em>This study aims to develop interactive learning media based on adobe flash by using the context of the Women's House Lubuklinggau City on valid and practical trigonometry material.
