ABSTRAKPenelitian ini bertujuan untuk mempelajari perilaku peternak sapi perah dan faktor yang mempengaruhinya dalam upaya meningkatkan skala ekonomi usaha. Metoda survey digunakan dalam penelitian ini dan diterapkan pada 75 peternak sapi perah di Kecamatan Getasan, Kabupaten Semarang. Sampel dipilih secara acak dari 3 desa yaitu Jetak, Batur dan Tajur, masing-masing 25 peternak. Data dianalisis dengan regresi model logit, menggunakan 15 indikator perilaku dan faktor sosial ekonomi sebagai prediktor (variabel bebas), yaitu umur peternak, pendidikan formal, jumlah anggota keluarga, pengalaman beternak, jumlah sapi yang dipelihara, produksi susu dan penguasaan lahan. Penelitian menunjukkan bahwa 40,04% peternak merupakan pengambil risiko yang bagus, 33,07% menengah dan 20,89% jelek. Perilaku peternak untuk meningkatkan skala ekonomi usaha dipengaruhi secara nyata oleh umur peternak, produksi susu dan jumlah sapi yang dipelihara. Odds ratio dari umur, produksi susu dan jumlah sapi secara berturut-turut adalah 0,93; 1,32 dan 1,37. Nilai-nilai ini mengandung arti bahwa setiap penambahan umur 1 tahun diikuti dengan kehilangan kemauan mengambil risiko sebesar 0,93 kali; setiap kenaikan produksi susu sebesar 1 liter akan diikuti dengan kenaikan kemauan mengambil risiko sebesar 1,32 kali dan setiap kenaikan jumlah sapi yang dipelihara sebesar 1 ST akan diikuti dengan kenaikan kemauan untuk mengambil risiko sebesar 1,37 kali.Kata kunci: perilaku peternak, skala ekonomi usaha, sapi perah, model logit
ABSTRACTThe objectives of the research were to investigate the behavior of dairy farmers and factors affecting the effort to enhance the economic of scale. Survey was conducted on 75 dairy farmers at Getasan District, Semarang Regency. Samples were drawn in random from villages of Jetak, Batur and Tajur, 25 farmers each. The data were analyzed by logit model regression, using 15 indicators of behavioural approach and socio-economic factors as predictors (independent variables) i.e. ages, formal education, family size, experience in cattle rearing, number of cattle raised, production of milk and land occupation. The result showed that 40.04% of the farmers were good, 33.07% were moderate and 20.89% were low risk takers. The farmers' behaviour in enhancing economic of scale significantly influenced by the farmers' age, milk production and number of cattle reared. The odds ratio of ages, milk production and number of cattle reared were 0.93; 1.32 and 1.37, respectively. These values indicated that as values of ages increased as much as 1 year, the values of the willingness on risk taking will decrease as much as 0.93 times; the values of milk production increase as much as 1 litre, the values of the willingness on risk taking will increase as much as 1.32 times; and the values of the number of cattle increased as much as 1 AU, the values of the willingness on risk taking will increase as much as 1.37 times.
