Optimasi Penggunaan Input Produksi pada Usahatani Kentang di Dataran Tinggi Dieng, Jawa Tengah. (Indonesian)

(The Optimization of Production Inputs Used in Potato Farming in Dieng Plateau, Central Java). (English)

Potato is one of the horticultural crops with high economic value and potential as an export commodity. The productivity of potatoes in Central Java tends to decrease, and it is suspected that the use of production inputs is not optimal. This study aims to evaluate the performance of the use of production inputs, the factors that influence potato production, and the optimization of the use of production inputs in potato farming in the Dieng Plateau. The research was conducted from October to December 2021 in Sumberejo Village, Batur Subdistrict, Banjarnegara District, which has an altitude of + 1700 meters above sea level. This research used a survey method on 30 potato farmers. The data obtained were analyzed descriptively, and analyzed the factors that influence production using multiple linear regression, followed by an optimization test on the use of production inputs. The results showed that the use of production inputs among farmers still varied and had not followed the results of soil analysis. Seed, manure, and labor are production inputs that have a significant positive effect on potato production. To get maximum production, farmers need to add seeds, NPK fertilizer, and manure according to recommendations, while the use of labor needs to be reduced to achieve optimal yields.

Kentang merupakan salah satu tanaman hortikultura yang memiliki nilai ekonomi tinggi dan berpotensi sebagai komoditas ekspor. Produktivitas kentang di Jawa Tengah cenderung menurun yang diduga karena penggunaan input produksi yang belum optimal. Penelitian ini bertujuan mengkaji keragaan penggunaan input produksi, faktorfaktor yang memengaruhi produksi kentang, dan optimasi penggunaan input produksi pada usahatani kentang di dataran tinggi Dieng. Penelitian dilaksanakan pada bulan Oktober–Desember 2021 di Desa Sumberejo, Kecamatan Batur, Kabupaten Banjarnegara yang memiliki ketinggian + 1700 mdpl. Penelitian dilakukan dengan metode survei pada 30 petani kentang. Data yang diperoleh dianalisis secara deskriptif dan analisis faktor-faktor yang memengaruhi produksi menggunakan regresi linear berganda, dilanjutkan dengan uji optimasi penggunaan input produksi. Hasil penelitian menunjukkan bahwa penggunaan input produksi antarpetani masih beragam dan belum mengikuti hasil analisis tanah. Benih, pupuk kandang, dan tenaga kerja merupakan input produksi yang berpengaruh nyata dengan tanda positif pada produksi kentang. Untuk mendapatkan produksi yang maksimal petani perlu menambahkan benih, pupuk NPK, dan pupuk kandang sesuai rekomendasi, sedangkan penggunaan tenaga perlu dikurangi untuk mencapai optimal.
