Forecasting Corn Production in Indonesia Using Holt–Winters Exponential Smoothing
No full textCorn is a strategic agricultural commodity in Indonesia due to its important role in national food security and the livestock feed industry. However, national corn production exhibits strong seasonal fluctuations that pose challenges for production planning and policy formulation. This study aims to forecast national corn production in Indonesia using the Holt–Winters Triple Exponential Smoothing method. Monthly corn production data from January 2020 to October 2025 obtained from the Central Agency of Statistics (BPS) were analyzed. A multiplicative Holt–Winters model was applied to capture level, trend, and seasonal components in the data. Forecasting accuracy was evaluated using the Mean Absolute Percentage Error (MAPE). The results show that the proposed model achieved a MAPE value of 18.64%, indicating reasonable forecasting accuracy. The forecasting results for the period November 2025 to December 2026 reveal a stable seasonal pattern in national corn production. These findings demonstrate that the Holt–Winters method is a practical and effective approach for short- to medium-term forecasting and can support agricultural planning and decision-making related to national food security

Analisis Kebutuhan dan Potensi Integrasi Nilai-Nilai Islam pada Materi Peran Air dalam Keberlangsungan Kehidupan dan Lingkungan pada Pembelajaran IPA Madrasah Ibtidaiyah
No full textMateri peran air dalam keberlangsungan kehidupan dan lingkungan merupakan salah satu topik penting dalam pembelajaran Ilmu Pengetahuan Alam (IPA) di Madrasah Ibtidaiyah (MI). Materi ini tidak hanya memiliki dimensi ilmiah, tetapi juga memiliki potensi besar untuk menginternalisasikan nilai-nilai Islam seperti tauhid, amanah, tanggung jawab, dan kepedulian lingkungan. Penelitian ini bertujuan untuk menganalisis kebutuhan dan potensi integrasi nilai- nilai Islam pada materi peran air dalam pembelajaran IPA MI. Penelitian menggunakan pendekatan deskriptif kualitatif dengan metode studi literatur, survei kebutuhan guru dan siswa MI, analisis konten buku teks IPA MI, serta observasi pelaksanaan pembelajaran. Hasil penelitian menunjukkan bahwa guru dan siswa membutuhkan pembelajaran IPA yang lebih kontekstual dan bermakna melalui integrasi nilai-nilai Islam. Buku teks IPA MI umumnya masih menekankan aspek kognitif dan belum mengintegrasikan nilai Islam secara eksplisit. Materi peran air memiliki potensi besar untuk menginternalisasikan nilai-nilai Islam melalui pengaitan ayat Al- Qur’an, hadis, serta pembiasaan sikap menjaga dan melestarikan sumber daya air. Penelitian ini merekomendasikan pengembangan pembelajaran IPA MI yang terintegrasi nilai-nilai Islam secara sistematis
