Abstract

Adenostemma platyphyllum is a weed plant containing various secondary metabolites, such as phenolics and flavonoids, making it essential to cultivate properly. This study aims to determine the optimal cow manure dosage for plant growth, focusing on phenolic and flavonoid production in the cultivation of A. platyphyllum. The experiment employed a randomized complete block design (RCBD) with a single factor: cow manure doses of 0.5, 5, 10, 15, and 20 ton/Ha. Phenolic content was measured using the Folin Ciocalteu reagent, while flavonoid content was assessed using the AlCl₃ reagent. Results indicate that the highest phenolic and flavonoid production occurred in plants treated with 20 ton/Ha manure. This dosage also resulted in the best plant growth, yielding the highest crop, number of leaves, and branches compared to other treatments.

Abstract

Harga beras di Indonesia memiliki peran penting dalam menjaga ketahanan pangan dan stabilitas ekonomi, karena sebagai makanan pokok, perubahan harga dapat memengaruhi kesejahteraan masyarakat dan laju inflasi. Oleh sebab itu, prediksi harga yang akurat menjadi kebutuhan strategis bagi pemerintah dan pelaku industri untuk menunjang pengambilan keputusan yang tepat. Penelitian ini mengevaluasi kinerja model regresi linear dan Prophet dalam memprediksi harga beras grosir di Indonesia, dengan menggunakan data historis dari BPS. Dengan metode Eksperimen Komparatif Kuantitatif, penelitian ini mengukur performa kedua algoritma menggunakan metrik Mean Absolute Error (MAE) dan Root Mean Squared Error (RMSE). Hasilnya menunjukkan Prophet memberikan prediksi lebih akurat dibanding regresi linear, karena mampu mendeteksi pola musiman dan tren jangka panjang yang penting, terutama pada periode-periode khusus seperti hari raya. Hasil prediksi ini dapat memberikan kontribusi bagi perencanaan pengendalian harga beras nasional.
