ANALISIS EFISIENSI PENGGUNAAN FAKTOR-FAKTOR PRODUKSI PADA PETERNAKAN SAPI PERAH (SURVEI PADA PETERNAK SAPI PERAH, KECAMATAN PANGALENGAN JAWA BARAT)

Abstract

A study had been carried out on the dairy farming sector in a Dairy Cooperative which the business sector is dominated by smallholder farming.  The objective of the study is to examine the possibility of the farmers increase their production scale by increasing the use of factors of production. Farm records from 1,251 members of the cooperative was analyzed to estimate the production function. The Cobb Douglas function is used as a hypothetical regression model that describes milk production (Y) is determined several factor of production. A dummy variable (D) is included in the model to describe the influence of the difference in dairy service. The regression analysis results in the estimated equation where Y = 6,123 X₁^0,704 X₂^0,249 X₃^0,015 e^0,018D. The variance analysis shows a significant effect of the explanatory variable on Y simultaneously. Partial t-test (P<0.05) verifies that the first two factors, namely herd size (X₁) and concentrate feed (X₂), each affects the milk production, while the effect of land (X₃) and the dummy variable (D) are insignificant. The statistical test of homogeneity the function accepts the null hypothesis of Ho: It is concluded that the output response is at the level of constant return to scale (RTS), it means that increasing all factors proportionally increases in milk production with the same proportion. At this production level, increasing the scale of production depends on the availability of the factors as well as decreasing the cost of production by increasing output.

Keywords: Cobb-Douglas, dummy, return to scale.
