Abstract

Penelitian ini dilatarbelakangi oleh rendahnya motivasi warga belajar mengikuti pelatihan membordir di PKBM Surya Kota Padang, hal ini diduga karena ada kaitannya dengan lingkungan belajar peserta mengikuti pelatihan membordir di PKBM Surya Kota Padang. Penelitian ini bertujuan untuk mendeskripsikan lingkungan belajar, motivasi warga belajar, dan keterkaitan keduanya. Jenis penelitian ini adalah penelitian kuantitatif yaitu deskriptif korelasional. Populasi penelitian adalah seluruh warga belajar yang mengikuti pelatihan membordir sebanyak 20 orang dan semua populasi dijadikan sampel, dengan teknik pengambilan sampel adalah quota sampling. Teknik pengumpulan data berupa kuesioner dengan alat pengumpul data berupa kuesioner. Teknik analisis data menggunakan rumus persentase dan korelasi Spearman rho. Hasil penelitian menunjukkan bahwa: (1) lingkungan belajar peserta diklat kurang kondusif, (2) motivasi warga belajar masih rendah, (3) terdapat hubungan yang signifikan antara lingkungan belajar dengan motivasi masyarakat. untuk belajar mengikuti pelatihan membordir di PKBM Surya Kota Padang. Disarankan agar lembaga PKBM Surya menyediakan lingkungan belajar yang kondusif agar peserta termotivasi untuk mengikuti pelatihan membordir. (3) Ada hubungan yang signifikan antara lingkungan belajar dengan motivasi belajar masyarakat mengikuti pelatihan membordir di PKBM Surya Kota Padang. Disarankan agar lembaga PKBM Surya menyediakan lingkungan belajar yang kondusif agar peserta termotivasi untuk mengikuti pelatihan membordir. (3) Ada hubungan yang signifikan antara lingkungan belajar dengan motivasi belajar masyarakat mengikuti pelatihan membordir di PKBM Surya Kota Padang. Disarankan agar lembaga PKBM Surya menyediakan lingkungan belajar yang kondusif agar peserta termotivasi untuk mengikuti pelatihan membordir.Kata kunci: lingkungan belajar, motivasi belajar

Abstract

Anthropogenic climate change is the primary cause of modern global warming and one of the greatest scientific challenges of the 21st century. This phenomenon is triggered by increasing concentrations of greenhouse gases (GHGs) such as CO₂, CH₄, N₂O, tropospheric ozone, and changes in aerosols that alter Earth's energy balance. This study aims to identify the latest scientific findings regarding the physical mechanisms that control anthropogenic warming and the Earth system's response to it. The method used is a Systematic Literature Review (SLR) of 30 primary research articles indexed by Scopus, Web of Science, Springer, MDPI, and Sinta (≥2) published in the period 2021–2025. The analysis is based on four research questions (RQs): the contribution of anthropogenic radiative forcing to Earth's Energy Imbalance, changes in atmospheric dynamics, the influence of climate feedbacks, and the response of Earth system components such as the ocean, cryosphere, biosphere, and atmosphere. The SLR results show that the increase in GHGs since the industrial era has resulted in significant positive radiative forcing, causing an increase in heat waves, changes in rainfall patterns, shifts in the jet stream and monsoon, and an intensification of ENSO variability. Furthermore, feedback mechanisms such as increased water vapor, decreased ice albedo, and cloud sensitivity amplify global warming, while carbon release from permafrost and decreased ocean absorption capacity increase long-term climate instability. This research confirms that anthropogenic climate change is an integrated process between the atmosphere, ocean, and biosphere, indicating the potential to reach tipping points. Strengthening climate physics modeling, improving the quality of observations, and integrating scientific findings into evidence-based mitigation policies are needed to prevent the acceleration of climate change in the future.

Abstract

This study aims to analyze the influence of GeoGebra-assisted Project Based Learning (PjBL) model on the ability of junior high school students to understand mathematical concepts and mathematical reasoning. This study uses a quantitative approach with a quasi-experimental method and a pretest-posttest nonequivalent control group design. The research population is all grade VIII students of SMP Negeri 47 Batam for the 2025/2026 academic year which totals 357 students. The research sample was selected using purposive sampling techniques, namely class VIII.5 as the experimental group and class VIII.4 as the control group, each totaling 40 students. The research instruments are in the form of a mathematical concept understanding test and a mathematical reasoning test in the form of a description that has met valid and reliable criteria. Data analysis was carried out using normality tests, homogeneity tests, and Independent Samples t-tests with the help of SPSS 25. The results showed that there was a significant difference between the ability to understand mathematical concepts of students in the experimental group and the control group with a significance value of 0.000 < 0.05. The same results were also found in mathematical reasoning ability with a significance value of 0.000 < 0.05. In addition, the percentage of achievement of mathematical concept comprehension skills is 86.07% and mathematical reasoning skills are 86.52%, which are included in the very good category. Thus, the GeoGebra-assisted PjBL model has proven to be effective in improving the conceptual understanding and mathematical reasoning skills of junior high school students
