ABSTRAK Tujuan penelitian ini adalah (1) mengetahui kevalidan pengembangan media pembelajaran diagram batang, diagram gambar, diagram garis (DITANGBARIS) pelajaran matematika kelas V materi penyajian data, (2) mengeetahui keefektifan pengembangan media pembelajaran diagram batang, diagram gambar, diagram garis (DITANGBARIS) pelajaran matematika kelas V materi penyajian data, dan (3) mengetahui kemenarikan pengembangan media pembelajaran diagram batang, diagram gambar, diagram garis (DITANGBARIS) pelajaran matematika kelas V materi penyajian data. Penelitian pengembangan ini menggunakan model peengembangan Borg and Gall. Berdasarkan hasil penelitian yang dilakukan, diperoleh hasil presentase kevalidan rata-rata media pembelajaran DITANGBARIS sebesar 88,33% dalam kategori sangat valid. Keefektifan media pembelajaran DITANGBARIS diukur melalui hasil belajar siswa dengan presentase ketuntasan klasikal sebesar 88,88% dengan kategori tuntas, sehingga dapat disimpulkan media pembelajajaran DITANGBARIS sangat efektif digunakan pada pembelajaran. Kemenarikan diukur dari presentase hasil angket respon siswa sebesar 94,88% dengan kategori sangat menarik. Berdasarkan hasil penelitian maka media pembelajaran DITANGBARIS valid, efektif dan menarik. Karena penelitian ini dilakukan hanya samapai tahap uji coba terbatas karena penelitian ini di lakukan pada saat adanya musibah pandemi covid-19 sehingga uji coba implementasi tidak dapat dilakukan. Kata Kunci: Pengembangan Media Pembelajaran Diagram Batang, Diagram Gambar, Diagram Garis (DITANGBARIS) Pelajaran Matematika Kelas V Materi Penyajian Data.

ABSTRACT The Purpose of this research is (1) to know the validity and development of the bar chart learning media, diagram of drawings, line diagrams (DITANGBARIS) lesson mathematics class V data presentation material, (2) know the effectiveness of the development of learning media bar chart, drawing diagram, line diagram (DITANGBARIS) lesson mathematics data presentation material, and (3) know the learning development of the study bar chart, drawing diagram, line diagram (DITANGBARIS) lesson math class V data presentation material. This development was used by Borg and Gall's model. Based on the results of the research conducted, the result of the percentage of the average study of the media of DITANGBARIS was 88.33% in a very valid category. The effectiveness of DITANGBARIS learning media was measured through students' learning outcomes with a classical and a classification of 88.88% in due category, so that the media can be concluded DITANGBARIS is very effective in use in learning. The proceeds are measured from the percentage of results of the student's response poll of 94.88% with very interesting categories. Based on the research results, the media learning DITANGBARIS valid, effective and interesting. Because this research is done only to the trial phase is limited because the research was conducted at the time of the Covid-19 pandemic disaster so that the implementation test is not possible. Keywords: Development Media Learning bar chart, drawing diagram, line diagram (DITANGBARIS) Lesson Math class V Data presentation material.
