“…Penggunaan konteks kebudayaan lokal erat kaitannya dengan salah satu dari 5 karakteristik Pendidikan Matematika Realistik Indonesia (PMRI). Salah satu pendekatan yang mengimplementasikan kontekstual yaitu PMRI (Zulkardi dan Ilma, 2006;Afriansyah, 2014;Afriansyah & Dahlan, 2017;Sarumaha, Putri, & Hartono, 2018;Cahirati, Makur, Fedi, 2020). Salah satu konteks kebudayaan lokal yang dapat digunakan yaitu kebudayaan lokal kota Palembang.…”

AbstrakEtnomatematika merupakan integrasi antara kebudayaan dan matematika sebagai salah satu usaha memperkenalkan budaya dan matematika secara bersamaan. Salah satu bentuk etnomatematika misalnya bangun bersejarah di kota Palembang yaitu Museum Negeri Sumatera Selatan Balaputera Dewa. Tujuan penelitian ini yaitu mengeksplorasi hubungan antara matematika dan budaya dalam seni arsitektur pada Museum Negeri Sumatera Selatan Balaputera Dewa dan mengenalkan konsep bangun datar melalui konteks Museum Negeri Sumatera Selatan Balaputera Dewa. Penelitian ini tergolong deskriptif kualitatif dengan studi pustaka. Subjek penelitian adalah salah seorang petugas Museum. Data dikumpulkan menggunakan prinsip etnografi melalui observasi, wawancara, dokumentasi, dan catatan lapangan. Teknik analisis data berupa hasil wawancara dan dokumentasi yang dikaitkan dengan kebudayaan dan matematika. Hasil penelitian ini yaitu eksplorasi hubungan antara matematika dan budaya, terutama dalam seni arsitektur pada Museum Negeri Sumatera Selatan Balaputera Dewa dan adanya konsep matematika yaitu bangun datar dari eksplorasi Museum Negeri Sumatera Selatan Balaputera Dewa. Ethnomathematics: Introduction of Plane Figure Through the Context of the South Sumatra State Museum Balaputera DewaAbstractEthnomathematics is an integration between culture and mathematics as an effort to introduce culture and mathematics simultaneously. One form of ethnomathematics, for example, is a historic building in the city of Palembang, namely the State Museum of South Sumatra Balaputera Dewa. The purpose of this research is to explore the relationship between mathematics and culture in architectural arts at the State Museum of South Sumatra Balaputera Dewa and introducing the concept of flat wakes through the context of the State Museum of South Sumatra Balaputera Dewa. This research is classified as descriptive qualitative with literature study. The research subject is one of the museum officers. Data collected using ethnographic principles through observation, interviews, documentation, and field notes. The data analysis technique was in the form of interviews and documentation related to culture and mathematics. The results of this study are the exploration of the relationship between mathematics and culture, especially in the art of architecture at the State Museum of South Sumatra Balaputera Dewa and the existence of a mathematical concept, namely the flat shape of the exploration of the Museum Negeri South Sumatra Balaputera Dewa.

AbstrakPenelitian ini dilatarbelakangi dari masalah rendahnya kemampuan proses kognitif siswa pada konsep perkalian. Tujuan penelitian adalah untuk mengetahui pengaruh teknik takalintarterhadap kemampuan proses kognitif pada konsep perkalian di sekolah dasar. Penelitian dilakukan pada siswa kelas III semester 1 tahun akademik 2017-2018 di Sekolah Dasar Negeri Nangela sebagai kelompok eksperimen, dan di Sekolah Dasar Negeri Cipaku 03 sebagai kelompok kontrol. Sampel penelitian yaitu 20 siswa dari masing-masing kelompok. Selama proses penelitian, kelompok eksperimen diberikan teknik takalintar, sedangkan kelompok kontrol diberikan pembelajaran konvensional. Pendekatan penelitian yang digunakan yaitu pendekatan kuantitatif dengan metode eksperimen kuasi desain Two Group Randomized Subject Posttest Only. Analisis data dilakukan dengan uji-t. Tingkat signifikansi 0,05. Hasil penelitian menunjukkan perbedaan yang signifikan antara skor kemampuan proses kognitif siswa dari kelompok eksperimen dan kelompok kontrol. Hasil uji effect sizemenunjukkan nilai sebesar 0,892, dengan interpretasi termasuk pengaruh yang tinggi. Sehingga dapat disimpulkan bahwa teknik takalintar memberikan pengaruh tinggi terhadap kemampuan proses kognitif siswa pada konsep perkalian. Oleh karena itu, teknik takalintardapat menjadi alternatif pembelajaran yang dapat diterapkan dalam upaya meningkatkan kemampuan proses kognitif siswa sekolah dasar. Abstract (The Effect of Takalintar Technique on Cognitive Processes Ability of Elementary School Students)This research is motivated from the problem of the low ability of students' cognitive processes on multiplication concepts. The aim of the study was to determine the effect of intelligent techniques on the ability of cognitive processes on the concept of multiplication in elementary schools. The study was conducted on third grade students of semester 1 of the 2017-2018 academic year in Nangela State Elementary School as an experimental group, and in Cipaku State Elementary School 03 as a control group. Research samples were 20 students from each group. During the research process, the experimental group was given takalintar techniques, while the control group was given conventional learning. The research approach used is a quantitative approach with the Two Group Randomized Subject Posttest Only quasi design experimental method. Data analysis was carried out by t-test. 0.05 significance level. The results showed a significant difference between students' cognitive process ability scores from the experimental group and the control group. The effect size test results show a value of 0.892, with interpretation including high influence. So it can be concluded that the takalintar technique has a high influence on the ability of students' cognitive processes on multiplication concepts. Therefore, takalintar technique can be an alternative learning that can be applied in an effort to improve the cognitive processing abilities of elementary school students.

“…One of the main factors causing the difficulty faced by students is the process learning percent itself [3]. It's not uncommon to learn percent done simply by introducing percent as a notation other than decimal or the form fractions per hundred [4] and only focuses on algorithms or routine procedures in completing problems [2].…”

“…Some of the findings of these previous studies signal that it is needed more meaningful learning for bridge students' understanding in understand the concept of percent comprehensively. Meaningful learning can be done by using real situations close to daily life of students [1,9] as well as through the use of concrete teaching aids or various representation models such as percentage bar [1,3,10]. Using the bar in completing problem about percent has several advantages [2,11,12].…”

This study aims to produce a learning trajectory to help students understand the concept of percent uses the context of the arrangement of books for class V. This research is based on the PMRI which associated with 2013 curriculum learning. The method used in this research is design research type validation study. This research was conducted in elementary school with involving 8 students of class V. Researchers designed 4 learning activities percent using the context of the book arrangement. This research aims to contribute to the form of: Local Instructional Theory (LIT) about percent material. This research involves in cycle 1 involving 8 students in elementary school. Data were collected through student worksheets, pre-test, post-test, video, and interview. Data were analysed by comparing Hypothetical Learning Trajectory (HLT) and what happens during the learning process. The result of this study shows that through a series of activities that have been carried out help students in learning material percent.
