AbstrakDesa Rumpin, Cipinang, Sukasari, dan Mekasari adalah empat desa pertanian padi sawah. Pada keempat desa ini terdapat 13 kelompok tani difasilitasi oleh satu orang penyuluh namun memiliki dinamika yang bervariasi, yang ditunjukkan oleh perbedaan status perkembangan masing-masing kelompok tani tersebut, yang dikelompokkan menjadi kelas pemula dan kelas lanjut. Peneliti berusaha menjawab permasalahan ini melalui penelitian dengan tujuan mengidentifikasi dan mendeskripsikan dinamika Kelompok Tani Padi Sawah (Oryza sativa L.) Desa Sukasari, Kecamatan Rumpin, Kabupaten Bogor. Penelitian dilaksanakan bulan Oktober sampai November 2020. Populasi adalah kelompok tani lanjut dan pemula sebanyak 80 orang. Selanjutnya pengambilan sampel dari setiap kelompok tani dilakukan secara acak proposional. Data yang dikumpulkan dalam penelitian ini terdiri dari data primer dan data sekunder. Data yang diperoleh dari hasil penelitian ini akan diidentifikasi secara deskriptif kualitatif. Hasil penelitian diperoleh bahwa dinamika kelompok Tani di Kecamatan Rumpin termasuk kategori rendah dan sedang. Dengan tingkat kedinamisan dalam kategori sedang dan rendah tersebut diharapkan anggota kelompok Tani Harapan Maju, Telaga Jaya, Rumpin Indah dan Aul Makmur dapat lebih memotivasi dan menggerakkan anggota kelompok dalam melaksanakan kegiatan kegiatan demi tercapainya tujuan kelompok, dan memahami unsur-unsur dinamika kelompok.AbstractRumpin, Cipinang, Sukasari, and Mekasari villages are four lowland rice farming villages. In these four villages, there are 13 farmer groups facilitated by one extension worker but have varying dynamics, which is indicated by the different development status of each farmer group, which is grouped into beginner and advanced classes. The researcher tries to answer this problem through research with the aim of identifying and describing the dynamics of the Padi Sawah Farmer Group (Oryza sativa L.) Sukasari Village, Rumpin District, Bogor Regency. The research was carried out from October to November 2020. The population was 80 advanced and novice farmer groups. Furthermore, sampling from each farmer group was carried out proportionally randomly. The data collected in this study consisted of primary data and secondary data. The data obtained from the results of this study will be identified descriptively qualitatively. The results showed that the dynamics of farmer groups in Rumpin sub-district were categorized as low and medium. With the level of dynamics in the medium and low categories, it is hoped that the members of the Harapan Maju, Telaga Jaya, Rumpin Indah, and Aul Makmur farmer groups can motivate and move group members in carrying out activities to achieve group goals and understand the elements of group dynamics.
