Abstract

Macadamia nut seeds are orthodox seeds that result in a dormancy period, so breaking the seed dormancy period is necessary. This study aims to determine the effect of drying and water immersion on dormancy breaking and macadamia bean seed germination and which drying and water immersion had the best impact on dormancy breaking and macadamia bean seed germination. The research was conducted in the soil laboratory and screen house of the Faculty of Agriculture, Winaya Mukti University, Tanjungsari District, Sumedang Regency, from June to November 2022. The experimental design used was a simple randomized block design (RBD) with a combination of drying and soaking seeds with nine treatment combinations. Each was repeated three times, so there were 27 experimental units. A = P 40oC + PA 45oC, B = P 45oC + PA 50oC, C = P 50oC + PA 55oC, D = P 50oC + PA 45oC, E = P 40oC + PA 50oC, F = P 45oC + PA 55oC, G = P 45oC + PA 45oC, H = P 40oC + PA 55oC, I = P 50oC + PA 50oC. The results showed that drying and soaking in water treatments at different temperatures had no significant effect on seed moisture content, seed cracking percentage, germination percentage, radicle length, and plumula length.

Abstract

This bibliometric analysis aims to see the opportunities and development of research trends related to mathematical critical thinking skills from 2019 to 2024. Through a bibliometric approach, this research will map publication trends based on the Scopus database by using Vos Viewer to analyze the data. The results of this study show the most publications and citations in 2020 as many as 55 publications and 777 citations, and a decrease in publications and citations from 2021 to 2024. Terms that are often related to mathematical critical thinking skills are students, problems, critical thinking, mathematics, and STEM.

Abstract

Abstrak. Jenis penelitian ini adalah kajian literatur yang didesain untuk menggali secara mendalam tentang pemberian scaffolding metakognitif dalam pemecahan masalah geometri terhadap data subjek-subjek bergaya belajar auditorial. Oleh sebab itu, peneliti mencari hasil penelitian disertasi dan artikel nasional maupun internasional terindex scopus kemudian menganalisanya sehingga diperoleh hasil penelitian bahwa dengan penerapan ekspositori atau pembelajaran langsung guru dapat mengajar secara rinci dengan melakukan metode yang berbeda dan berkelanjutan secara rutin seperti menampilkan video, gambar, dan mendengarkan musik. Guru juga mengarahkan siswa untuk berdiskusi dengan temannya agar mereka saling bekerjasama dalam memahami materi yang sedang dipelajari. Guru dapat memberikan scaffolding metakognitif untuk meningkatkan pencapaian belajar siswa serta mendukung proses monitoring dan kontrol siswa-siswanya. Guru dapat menggunakan media ajar teknologi Realitas Virtual (VR) dan Augmented Reality (AR) juga semakin diperkenalkan dalam konteks pembelajaran audio visual, memungkinkan pengalaman pembelajaran yang lebih interaktif dan mendekati realitas dalam pemecahan masalah geometri bangun ruang.
