Abstract

RLS (rata-rata lama sekolah) merupakan salah satu indikator kualitas sumber daya manusia di suatu wilayah. Saat ini capaian RLS penduduk usia 25 tahun ke atas di Kalimantan Tengah sebesar 8,96 (belum lulus SMP) dan berada di peringkat 21 dari 38 provinsi. Tujuan artikel ini adalah melakukan proyeksi RLS sampai 2045 (tahun Indonesia emas) dan mendeskripsikan rekomendasi strategi untuk mencapai proyeksi tersebut. Penelitian ini menggunakan pendekatan berbasis data sekunder (documentary research). Datanya adalah dokumen kebijakan pendidikan yaitu peraturan pemerintah atau kementerian, dan laporan statistik resmi dari Badan Pusat Statistik dan Kementerian Pendidikan Dasar dan Menengah. Proyeksi RLS menggunakan metode double exponential smoothing dengan bantuan aplikasi Minitab 18. Hasilnya RLS penduduk usia 25 tahun ke atas di Kalimantan Tengah sebesar 12 dicapai pada tahun 2041. Proyeksi RLS tersebut di tahun 2045 sebesar 12,71. Strategi peningkatan RLS adalah pendataan kecamatan/kelurahan/desa dengan angka putus sekolah yang masih tinggi dilanjutkan dengan implementasi kebijakan yang spesifik di suatu daerah tertentu, penurunan angka pernikahan dini, dan pembangunan sekolah program pendidikan kesetaraan beserta peningkatan kualitas sarana dan kompetensi guru bagi sekolah yang ada saat ini.

Abstract

Background: Conventional mathematics instruction rarely integrates environmental sustainability themes, limiting students' opportunities to develop both mathematical reasoning and ecological awareness. Objective: This study developed and evaluated a PjBL–STEM learning design to simultaneously enhance mathematical critical thinking and environmental literacy among elementary students through plastic waste recycling projects. Methods: Using the 4-D R&D model followed by a quasi-experimental nonequivalent control group design, 32 elementary students selected via purposive sampling participated. Instruments were validated through expert judgment (Cronbach's α = 0.87). Data were analyzed using an independent samples t-test after normality and homogeneity tests (α= 0.05). Results: The PjBL–STEM model significantly improved students' critical thinking (t = 4.32, p < 0.05). Post-test mean scores of the experimental group (M = 91.25, SD = 5.84) significantly exceeded those of the control group (M = 74.50, SD= 8.21). Students demonstrated strong performance across all five critical thinking indicators. Conclusion: PjBL–STEM learning effectively integrates mathematical critical thinking and environmental literacy, offering a reproducible interdisciplinary model for sustainability-oriented mathematics education.
