Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor risiko dominan dari sisi people dan planet yang memengaruhi penurunan produktivitas dan profitabilitas petani bawang merah dan padi, menganalisis dampak pengurangan pupuk kimia dan penambahan pupuk organik terhadap produktivitas dan biaya produksi serta mensimulasikan dampak jangka panjangnya menggunakan pendekatan sistem dinamis. Model ini dibangun menggunakan perangkat lunak Stella dengan skenario pemupukan kombinatif: NPK 750 kg/ha, pupuk cair cair organik 6liter/ha, dan bokashi 10 ton/ha. Hasil menunjukkan bahwa risiko people terbesar adalah usia petani yang mayoritas di atas 56 tahun serta rendahnya adaptasi teknologi. Risiko dari sisi planet meliputi tingginya serangan hama dan degradasi tanah akibat pupuk kimia berlebih. Skenario pemupukan organik menghasilkan peningkatan produktivitas bawang merah hingga 10%-15% dan padi sekitar 8-12%, serta menurunkan biaya pupuk hingga 30%. Nilai produktivitas tersebut setara dengan Rp. 176.400.000/ha/musim untuk bawang merah dan Rp. 25.000.000/ha/musim untuk padi. Simulasi jangka panjang menunjukan bahwa tanpa upaya pembaruan, produktivitas dapat menurun 5-8% per tahun. Sebaliknya, kombinasi intervensi organik dan mekanisasi terbukti mampu meningkatkan hasil, efisiensi biaya, dan menarik minat petani muda.
