Abstract

RINGKASAN Tujuan penelitian ini adalah untuk mengetahui motivasi apa sebenarnya yang mendorong para peternak sapi potong bergabung dalam sistem pemeliharaan kandang kelompok, serta untuk melihat apakah ada perbedaan motivasi antaranggota pada kelompok pemrakarsa yang berbeda. Penelitian dilakukan di Kecamatan Sanden, Kabupaten Bantul, Yogyakarta pada bulan September - Desember 2003. Pengambilan sampel dilakukan dengan teknik quota sampling. Kelompok ternak sapi potong yang ada dibedakan menjadi 3 kelompok berdasarkan unsur pemrakarsanya, yaitu oleh Dinas Peternakan, pemerintah desa, dan swadaya. Sampel sebagai responden diambil dalam jumlah yang seimbang antar ketiga kelompok, masing-masing 20 peternak, sehingga total responden adalah 60 peternak. Alat pengumpul data yang digunakan berupa daftar kuesioner. Indikator yang dijadikan sebagai petunjuk motivasi dikategorikan ke dalam lima aspek sesuai dengan rancangan Maslow (1994), dan untuk menganalisis intensitas motivasi digunakan model Clark Hull (Petri, 1981). Hasil penelitian memperlihatkan bahwa secara umum motivasi peternak ikut serta dalam membentuk kandang komunal tidak hanya semata-mata didasari oleh keuntungan secara ekonomis, supaya mendapatkan penghargaan atau supaya diakui eksistensinya, tetapi lebih didasari oleh dorongan untuk meningkatkan kualitas hubungan kehidupan sosial di antara peternak/masyarakat. Motivasi keikutsertaan anggota kelompok yang dibentuk oleh Dinas Peternakan cenderung pada kebutuhan untuk aktualisasi diri, motivasi keikutsertaan anggota kelompok yang dibentuk oleh pemerintah desa adalah didorong oleh pemenuhan kebutuhan fisiologis, sedangkan keikutsertaan anggota pada kelompok swadaya lebih didasari oleh dorongan kebutuhan sosial dan kasih sayang.

Abstract

The training of intensive breeding management has been carried out for duck farmers at district Wedung - Demak, on July-August 2013. The training was conducted in three activities, namely: (a) the transfer of knowledge about technique of preparing duck feed by available material, intensive maintenance , and incubator hatching technique; (b) implementation of intensive maintenance for the fertile eggs product, and (c) the practice of using the hatching incubator. Participants were duck farmer at Mutih Kulon and Tedunan, that maintain their ducks with extensive (grazing method). The results showed that the 27 participants who took the training have never been participated in the training of duck management. The reason of farmer breeding with grazing method, because they follow the habits of their parents. Most participants know that the maintenance of grazing method is bad, and they know that the intensive maintenance will increase the profits. The Proximate analysis of ration duck showed that its composition has taught balanced feed criteria. Production of eggs in the intensive maintenance hatchability reached 92%, eventhough the experiment at the farmer level reached 70.5% only.
