Abstract

This study aims to explore how Montessori didactic materials help elementary school students understand the concept of fractions. Using qualitative methods and a Design Didactic Research (DDR) approach, data were collected through classroom observations, semi-structured interviews with Montessori teachers, and documentation of student work. The data analysis technique used was thematic analysis, where the researcher identified patterns and main themes from the data collected. Triangulation was conducted to validate the research results by combining findings from interviews, observations, and documentation. The results showed that the use of concrete manipulative materials significantly improved students' understanding of fractions, developed problem-solving skills, and built a strong connection between abstract and real concepts. The teacher acts as a facilitator, allowing students to learn independently while still guiding them in the exploration process. This study concludes that the Montessori method is effective in teaching fractions at the primary school level, by providing a deep and meaningful learning experience for students.

Abstract

Pendidikan kesehatan gigi dan mulut merupakan komponen esensial dalam mencegah masalah oral, terutama pada anak-anak sekolah dasar. Di UPTD Puskesmas Cot Ba’u Kota Sabang, tercatat 89% kunjungan karena masalah gigi, dengan pencabutan gigi sebagai tindakan utama karena karies. Pada SD Negeri 16 Bay Pass, 89% siswa mengalami karies dengan rata-rata tiga gigi terdampak. Tujuan Penelitian untuk mengetahui hubungan antara perilaku menggosok gigi dengankebersihan gigi dan mulut pada anak usia Sekolah Dasar Negeri 16 Bay Pass Gampong Cot Bau Kota Sabang. Penelitian menggunakan tehnik proporsional sampling dengan menggunakan rumus Slovin sehingga diperoleh sampel sebanyak 51 orang, yang dilakukan pada tanggal 10 – 14 Juni 2024. Analisis data menggunakan Uji Chi-square dengan taraf nilai < 0.05. Hasil penelitian dari 51 responden diperoleh perilaku menggosok gigi dalam kategori baik sebanyak 32 siswa (62.7%), perilaku menggosok gigi dalam kategori kurang sebanyak 19 siswa (37,3%), sedangkan status kebersihan gigi dan mulut siswa dengan 12 siswa (23,5%) memiliki status baik, 26 siswa (51.0%) memiliki status sedang, dan 13 siswa (25,5%) memiliki status kurang. Berdasarkan hasil penelitian dapat disimpulkan Bahwa ada hubungan yang signifikan antara perilaku menggosok gigi dengan kebersihan gigi dan mulut pada anak SD Negeri 16 Bay Pass dengan nilai p value = 0,001 (p<0,05). Untuk meningkatkan perilaku menggosok gigi maka dapat memberikan penyuluhan kepada anak usia sekolah dasar di SD Negeri 16 Bay pass Gampong Cot Bau Kota Sabang tentang kebersihan gigi dan mulut serta mengajak Anak usia sekolah dasar untuk menjaga kebersihan gigi dan mulut supaya dapat mencegah dari masalah kesehatan gigi dan mulut.

Abstract

Green betel leaf contains phenolic compounds that can bind metal ions. The purpose of this study was to determine the effect of variations in the mass of green betel leaf and stirring time based on the efficiency and adsorption capacity of lead and copper metals in artificial wastewater. Adsorption process using the stirring with a magnetic stirrer. The variation used is the stirring time of 30 and 60 minutes and the mass of the adsorbent is 25,30,35, 40 grams. Artificial wastewater is made from 1 gram of each Pb(NO3)2 and CuCl2.2H20 in 500 ml of aquadest. Analysis of the metal using the AAS (Atomic Absorption Spectrophotometry). The results of the analysis showed that the optimum adsorption of lead metal was at a mass of 30 grams of betel leaf and a stirring time of 1 hour, where green betel leaves were able to adsorb 99.96% of lead metal, from a Pb level of 6435 ppm to 2.48 ppm. While the optimum results for adsorption of copper metal were 35 grams of betel leaf mass and 30 minutes of stirring time, where green betel leaves were able to adsorb 49.83% copper metal, from 158 ppm Cu level to 79.27 ppm.
