Judul: Keefektifan sistem kerja laku dalam program penyuluhan pertanian pada petani peserta supra insus
Abstrak: Teknologi Supra Insus padi sawah diterapkan pada petani dalam rangka melestarikan keberhasilan swasembada beras dan peningkatan pendapatan petani. Teknologi tersebut hanya dapat dilaksanakan secara sempurna melalui kerja sama antar petani dalam ikatan kelompok, selain itu program ini meng- upayakan agar proses adopsi teknologi oleh petani berlang- sung dengan cepat dan lancar, sehingga perhatian ditujukan pada peningkatan pengetahuan, sikap, keterampilan, dan pro- duktivitas usaha petani. Dengan demikian tanpa mengecil- kan arti dan peranan unsur-unsur lainnya, keberhasilan pro- gram Supra Insus ini terletak pada kemampuan petani/kelom- pok tani dalam menerapkan teknis budidaya, serta peranan PPL selaku pembimbing teknis dan agent of change. Pelaksanaan program penyuluhan pada petani peserta Su- pro Insus melalui sistem kerja Latihan dan Kunjungan (LA- KU), merupakan faktor yang berpengaruh terhadap efektivitas penyuluhan. Efektivitas penyuluhan ini terutama ditinjau pada pencapaian perubahan perilaku petani pada aspek penge- tahuan, sikap, dan keterampilan, dalam menerapkan teknologi Supra Insus....

Judul: Pengukuran Jantung Kelinci New Zealand White (Oryctolagus cuniculus) dengan Radiografi Toraks
Abstrak: This research was conducted to evaluate radiographs heart size of anaesthetized New Zealand White rabbits (Oryctolagus cuniculus) under different combination of ketamine and xylazine. The rabbits were divided into three groups. Group A were anaesthetized using a 35 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=5). Group B were anaesthetized using a 40 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3) while group C were anaesthetized using 45 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3). Parameter of observation from left laterolateral view were: 1) the apicobasilar length of the heart (AB), 2) the width of the heart (CD), 3) the distance between the cranial edge of the fifth rib and the caudal edge of the seventh rib perpendicular to the spine (R5-7), and 4) the vertical depth of the toraks (H). Parameter of observation from dorsoventral view were: 1) the length of the heart (L), 2) the width of the heart (W), and 3) the width of the thorax (T). The result from the heart parameters observation that were measured in left laterolateral view and dorsoventral view shows theres no significantly differ among the groups (P > 0.05). The vertebrae heart size (VHS) values obtained from the sum of the length of the long and the short axes on left laterolateral view. The long axes mean values (A) were 4.35±0.26 v and the short axes mean values (B) were 3.59±0.30 v, therefore VHS mean values were 7.94±0.49 v. On the dorsoventral view, the length of the heart mean values (L) were 4.32±0.29 cm, the width of the heart mean values (W) were 3.33±0.26 cm, and the width of the thorax mean values (T) were 5.85±0.30 cm. In normal conditions, the width of the heart should be less than two-thirds the width of the thorax and values obtained of 3.33<3.72 it shows that the heart is in the normal range. The best ratio to calculated the normal heart dimension in the left laterolateral view was compared the long axes with the vertical depth of the thorax, whereas in dorsoventral view, the length of the heart was compared with the width of the heart.
