Technical Efficiency Analysis and The Determinants of Inefficiency Factors of Beef Cattle Fattening in Gorontalo District. Beef cattle farming in Gorontalo Province generally is managed by household farmers. However, smallholder cattle operations have several problems like low productivity, small bussiness scale and traditional management. The objectives of this study are to estimate level of technical efficiency of beef cattle production and to assess the effect of socio-economic factors on the technical efficiency. Thirty respondents in Tolangohula Sub district, Gorontalo District, Gorontalo Province were selected by accidental sampling method and analyzed using stochastic frontier production function. Results of the analysis showed that the beef cattle farming was feasible but the level of technical efficiency was low with an average efficiency index of 0.690. There were chances to increase in efficiency by 31%. Factors that affected the production of beef cattle were labors, forages and feeder cattleweight while the inefficiency was determined by the ownership status of the beef cattle and the intensity of the extension. Therefore, an access to resources such as technical training and access to an increased number of cattles through a capital increase needed to be developed.Keyword : beef cattle, technical efficiency, Gorontalo ABSTRAK Secara umum budidaya penggemukan sapi potong di Provinsi Gorontalo dikelola oleh peternak rakyat dengan ciri-ciri diantaranya produktivitas usaha rendah, skala usaha kecil dan pengelolaan tradisional. Usaha ini menjadi unggulan untuk memenuhi kebutuhan konsumsi daging sapi. Tujuan penelitian adalah menganalisis tingkat efisiensi teknis dan faktor penentu inefisiensi usaha penggemukan sapi potong. Pengambilan data dilaksanakan di Kecamatan Tolangohula, Kabupaten Gorontalo pada bulan Oktober-November 2013. Penelitian menggunakan data primer yang diperoleh dari 30 peternak yang dipilih dengan metode accidental sampling. Data kemudian dianalisis menggunakan fungsi produksi stokhastic frontier. Hasil analisis menunjukkan bahwa usaha penggemukan sapi potong layak diusahakan namun capaian efisiensi teknis usaha sapi potong masih rendah dengan nilai indeks efisiensi rata-rata sebesar 0,690. Faktor yang mempengaruhi produksi sapi potong yaitu tenaga kerja, pakan hijauan dan bobot bakalan. Sementara inefisiensi usahatani ditentukan oleh status kepemilikan sapi dan intensitas penyuluhan. Oleh karena itu, akses terhadap sumber informasi seperti pelatihan teknis dan akses terhadap peningkatan jumlah sapi melalui peningkatan modal perlu terus dikembangkan.Kata Kunci : efisiensi teknis, penggemukan sapi potong, faktor,faktor penentu inefisiensi,etani
