Abstract

Abstrak Penelitian ini merupakan penelitian deskriptif-kualitatif dengan menggunakan metode penelitian kepustakaan (Library Research) yaitu penelitian yang mengkaji kepustakaan, khususnya tentang the rearrangement Inequality  dengan tujuan untuk mengumpulkan data dan informasi dengan bantuan bermacam material seperti buku-buku dan dokumen yang ada. Adapun permasalahan dalam penulisan ini adalah bagaimana hubungan antara ketaksamaan Rataan Kuadrat, Aritmatika, Geometri, Harmonik dan bagaimana membuktikan Rearrangement Inequality dari pertidaksamaan Rataan Kuadrat, Aritmatika, Geometri, Harmonik. Hasil pembahasan menunjukkan dengan masing-masing ketaksamaan memiliki hubungan, sehingga Rearrangement Inequality dapat diturunkan atau dibuktikan dari ketaksamaan-ketaksamaan tersebut. Kata kunci: Rearrangement Inequality, ketaksamaan Abstract This research is a  descriptive-qualitative  research methods literature  (Library Research)  research that examines  the literature, especially  concerning  the  rearrangement  Inequality  in order to gather data and  information with the help of a variety of materials such as books and documents. The problem in this paper is how the relationship  between  inequality  Mean  Squares, Arithmetic, Geometry, Harmonics and how to prove Rearrangement  inequality Inequality of Mean Squares, Arithmetic, Geometry, Harmonics. The results show discussion with each inequality have a relationship, so Rearrangement  Inequality  can be derived  or evidenced  from  the inequality-inequality.

Abstract

The purpose of this study is to describe the ability of students in constructing the concept of symmetry group. This research was conducted in STKIP PGRI Tulungagung, subjek in this research is PGSD student of Semester VI, Data collection with written test, interviews and documentation. Written tests and interviews were conducted to obtain student data in building understanding of the concept of symmetry group, While documentation is used to record all activities in building understanding of the concept of Symmetry group. The results of this study indicate that At the stage of action the subject is able to show the next steps of showing the permutation link with an equilateral triangle, At the stage of the process is able to show the next steps of imagining the reflection of the triangle, And determine reflection, At the stage of the subject object is confident with the done and able to explain the next steps of imagining the reflection properties of the triangle wake up, and determine the reflection From the nature of the reflection is changed again into a transformation composition, At the subject schema stage can already explain if the triangle is altogether converted into a rectangular or pentagonal wake, then the reflection and composition of its transformation will change, it indicates that the subject already has a scheme about symmetry group.

Abstract

It is essential to improve students' numeracy literacy skills to apply concepts in everyday life and interpret information correctly, so interactive learning media is needed to support this. However, teachers need to be more optimal in using interactive learning media so that numeracy literacy skills are low. This study aimed to develop interactive media based on Adobe Flash Media CS6, the development used as ADDIE. The stages of this research model include Analysis, Design, Development, Implementation, and Evaluation. The results of this study indicate that the development of interactive learning media based on Adobe Flash CS6 can improve numeracy literacy skills. This can be seen from the average percentage of validity of 87% with very valid criteria, media expert validation of 78.3% with valid criteria, and practitioner validation of 94.2% with very valid criteria, besides that the average percentage of practicality obtained from the results of the black box testing questionnaire on five different types of android devices and types, 100% was successfully used. The percentage of effectiveness was 0.49, and the criteria were moderate. For this reason, interactive learning media based on Adobe Flash CS6 can be used as alternative learning at Madrasah Ibtidaiyah to improve numeracy literacy skills.Kemampuan literasi numerasi siswa penting untuk ditingkatkan agar siswa dapat mengaplikasikan konsep dalam kehidupan sehari-hari serta menginterpretasi informasi dengan baik, sehingga diperlukan media pembelajaran interaktif untuk mendukung hal tersebut. Namun guru belum maksimal dalam menggunakan media pembelajaran interaktif sehingga kemampuan literasi numerasi rendah. Tujuan penelitian ini adalah untuk mengembangkan media interaktif berbasis adobe media flash cs6, pengembangan yang digunakan adalah ADDIE. Adapun tahapan dari model penelitian ini meliputi: Analysis, Design, Development, Implementation, dan Evaluation. hasil dari penelitian ini menunjukkan bahwa pengembangan media pembelajaran interaktif berbasis adobe flash cs6 dapat meningkatkan kemampuan literasi numerasi. Hal ini dapat dilihat dari rata-rata persentase kevalidan sebesar 87% kriteria sangat valid, validasi ahli media sebesar 78,3% kriteria valid, dan validasi praktisi sebesar 94,2% dengan kriteria sangat valid, selain itu rata-rata persentase kepraktisan yang diperoleh dari hasil angket uji coba blackbox testing pada 5 perangkat android yang berbeda jenis dan tipe sebesar 100% berhasil digunakan dan persentase keefektivan sebesar 0,49 kriteria sedang. Untuk itu media pembelajaran interaktif berbasis adobe flash cs6 bisa digunakan alternatif pembelajaran di Madrasah Ibtidaiyah untuk meningkatkan kemampuan literasi numerasi.
