Judul: The Relationship between Communication Network and Dissemination of Garden Tower Innovation in Women Farmer's Group
Abstrak: Jaringan komunikasi yang terbentuk di KWT dapat digunakan sebagai media dalam diseminasi terkait inovasi pertanian, salah satunya adalah Garden Tower yang dikembangkan oleh IPB dan USANA. Tujuan dari penelitian ini adalah untuk menganalisis jaringan komunikasi dan diseminasi Garden Tower serta hubungan di antara keduanya yang di KWT Melati dan Sekar Asri. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif serta didukung oleh data kualitatif. Teknik pemilihan responden yang digunakan adalah teknik sampel jenuh. Hasil dari penelitian ini menunjukkan bahwa aktor yang sama menempati degree centrality, closeness centrality, dan betweenness centrality paling sentral dalam jaringan. Tingkat penilaian terhadap metode, model, dan strategi dalam diseminasi Garden Tower juga tergolong tinggi. Hasil uji korelasi menunjukkan adanya hubungan yang signifikan antara lama berusahatani dan lama keanggotaan dengan degree centrality, tingkat pendidikan dengan closeness centrality, dan tingkat pendidikan, lama berusahatani dan lama keanggotaan dengan betweenness centrality. Terdapat hubungan yang signifikan juga antara closeness centrality dan betweenness centrality dengan tingkat penilaian terhadap metode demonstrasi plot, model top-down, dan strategi fasilitatif., Communication networks formed in the Women Farmer’s Group can be used as a medium for disseminating related to agricultural innovation, one of it is the Garden Tower developed by IPB and the USANA. The aim of this research is to analyze the communication network and dissemination of Garden Tower as well as the relationship between them at KWT Melati and Sekar Asri. The method used in this research is a quantitative method and supported by qualitative data. The respondent selection technique used was a saturated sampling technique. The results of this research show that the same actors were in the most central of degree centrality, closeness centrality, and betweenness centrality in the network. The level of assessment of methods, models, and strategies in disseminating Garden Tower is also relatively high. The results of the correlation test show that there is a significant relationship between length of farming and length of membership with degree centrality, level of education with closeness centrality, and level of education, length of farming, and length of membership with betweenness centrality. There is also a significant relationship between closeness centrality and betweenness centrality with the level of assessment of plot demonstration methods, top-down models, and facilitative strategies.

Judul: Analisa jaringan komunikasi dalam difusi inovasi pertaqnian di pedesaan:penelaahan terhadap peranan kelompok tani : kasus di desa Cibeber I dan Purasari, Kecamatan Leuwiliang, kabupaten Bogor
Abstrak: Dalam pembangunan masyarakat proses difusi inovasi sangat berperan penting. Beberapa teori komunikasi dipergunakan untuk menjelaskan proses difusi inovasi ini, diantaranya teori stimulus-respons, teori komunikasi dua tahap, dan teori komunikasi banyak tahap. Teori-teori tersebut menggambarkan proses komunikasi sebagai suatu yang linier di mana fokusnya adalah individu sebagai unit analisa, tanpa melihat hubungan antar individu. Pada masa sekarang para ahli komunikasi mulai mengubah pandangan mereka dari individu sebagai unit analisa kepada analisa hubungan antar dua orang, klik, jaringan atau sistem. Inilah yang disebut dengan analisa jaringan komunikasi, atau sering juga disebut analisa jaringan sosial, di mana fokusnya adalah hubungan antar pribadi yang didasari komunikasi interpersonal. Di sisi lain banyak kelompok tani yang belum berfungsi sebagai wadah penyebaran inovasi pertanian sebagaimana mestinya, oleh karena itu penelitian ini hendak menganalisa keberadaan kelompok tani dengan menggunakan analisa jaringan komunikasi. Tujuan penelitian ini ialah 1) menganalisa sumber informasi pertanian bagi petani, mempelajari keterlibatan media massa dan tokoh masyarakat dalam difusi inovasi pertanian, 2) menganalisa struktur dan ciri jaringan ko- munikasi dalam kelompok tani di pedesaan, mempelajari bagian-bagian jaringan komunikasi dan peranannya serta mempelajari perbedaan antara jaringan komunikasi kelompok tani di daerah pertanian yang berhasil dan di daerah yang kurang berhasil, 3) menganalisa peranan kelompok tani dalam penyebaran inovasi pertanian di pedesaan serta menganalisa pola hubungan yang terjadi dalam jaringan komunikasi kelompok dan latar belakang hubungan tersebut...

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
