Abstract

Sektor pertanian di Indonesia, yang didominasi oleh tanaman kacang tanah sebagai sumber pangan kaya protein dan lemat, menghadapo tantangan produktivitas akibat ketidaksesuaian lahan dan juga kondisi udara, seperti suhu dan kelembaban yang tidak optimal. Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara suhu dan kelembaban udara dengan produktivitas dan produksi kacang tanah di 34 provinsi di Indonesia untuk memahami dampaknya terhadap hasil pertanian dan ketahanan pangan di Indonesia. Pada penelitian ini, metode penelitian yang digunakan adalah analisis korelasi kanonik. Penelitian ini menggunakan data sekunder, yang merujuk pada informasi yang diperoleh dari sumber data Badan Pusat Statistik (BPS) melalui e-book statistika lingkungan hidup di Indonesia tahun 2022. Berdasarkan analisis korelasi kanonik disimpulkan bahwa hubungan antara suhu udara terhadap produktivitas kacang tanah mengakomodasi 99,26487% hubungan kanonikal, lalu 0,73513% diakomodasi dalam hubungan antara kelembaban udara terhadap produksi kacang tanah. Kesimpulan dari penafsiran koefisien variabel kanonikal, termasuk bobot, muatan, dan muatan-silang, menunjukkan bahwa terdapat interaksi antara suhu dan kelembaban udara dengan produktivitas dan produksi kacang tanah di Indonesia.

Abstract

This study addresses the ongoing challenge of clarifying the risk factors contributing to Alzheimer's disease, a neurodegenerative condition marked by progressive cognitive decline and memory dysfunction, with cases rising globally. To provide a more accurate and comprehensive understanding of the predictors associated with the disease, this research models the contributing factors using logit, probit, and gompit link functions within the Generalized Linear Model (GLM). Utilizing secondary data from 2024, which includes predictor variables such as age, family history, head injury, hypertension, memory complaints, and behavioral disturbances, this research models the relationship between these variables and Alzheimer's diagnosis. The analysis finds that the logit, probit, and gompit link functions yield significant results in identifying risk factors associated with Alzheimer's diagnosis, particularly memory complaints and behavioral disturbances. The gompit link is selected as the best model due to its highest deviance R-squared value of 30.01%, indicating better reliability in predicting Alzheimer's diagnosis than other models. This GLM approach provides insights to support early prevention and intervention efforts for Alzheimer's disease and contribute to achieving Sustainable Development Goals (SDGs) number 3 on good health and well-being.
