Pengaruh Pengeluaran Input Produksi Terhadap Produksi Usahatani Jagung Hibrida Pada Lahan Sawah Kecamatan Utan Kabupaten

Abstract

This study aims to: (1) determine the simultaneous effect of production input expenditure on the production of hybrid corn farming on paddy fields in Utan Subdistrict, Sumbawa Regency; (2) determine its partial effect on hybrid corn production in the same area; and (3) determine the strength of the combined production input expenditure in influencing hybrid corn production. The research was conducted in Utan Subdistrict, Sumbawa Regency, from April to June 2025. The sample was selected through purposive sampling, in which five farmer groups with the largest membership were chosen as sampling units; seven farmers were selected from each group, yielding a total of 35 respondents. Data were analyzed using multiple regression analysis, the t-test, the F-test, and the coefficient of determination (R²). The results show that, simultaneously, the variables of land area, seed cost, fertilizer cost, pesticide cost, and labor cost have a significant effect on hybrid corn production, with a calculated F-value greater than the F-table value at the 5% significance level. Partially, land area, fertilizer cost, and pesticide cost have a significant effect on hybrid corn production (calculated t-value > t-table value), whereas seed cost and labor cost do not (calculated t-value < t-table value). The coefficient of determination (R²) of 0.921 indicates that the combined variables explain 92.1% of the variation in hybrid corn production, with the remainder influenced by other factors outside the model.
