Abstract

This study was aimed to evaluate the utilization of banana peel meal as alternatives to substitution of corn in the diets based on the histomorphology of intestinal villi and visceral organ on hybrid ducks. A total of 105 male day old duck used in a completely randomized design (CRD) with 7 treatment was done through 3 replications, with each replication consisted of 5 Hybrid ducks. The treatment used is replacing corn wtith banana peel meal half of it (25%) and all of it (50%), PB= basal feed without banana peel meal; K25 and K50 = basal feed with kepok banana peel meal; T25 and T50 = basal feed with tanduk banana peel meal; R25 and R50 = basal feed with raja banana peel meal. If was significant differences were analyzed using orthogonal contrast. The paramater collected are high and width of villi and visceral organ on the Hybrid ducks. The results of the study showed that the utilization of 3 different types of banana peel meal on ducks have no significant effect on high and width of villi and visceral organ. It could be concluded that 3 different types of banana peel meal have no content or substances that can change high and width of villi and viceral organ on hybrid ducks.

Abstract

Sorghum is a potential feed crop to be developed in the tropics that has a long dry season such as in Indonesia. This study aims to determine the effect of harvesting age and nitrogen fertilizer level on the production and nutrient content of sorghum plants Numbu varieties. This study used a split block design with 2 factors and the difference between averages was tested with Duncan's Multiple Range Test (DMRT). The main factors are the age of harvest time consisting of U1 (50 days), U2 (60 days) and U3 (70 days). The second factor is the nitrogen fertilizer level which consists of P1 (0 kg / ha), P2 (100 kg / ha), and P3 (200 kg / ha). Each treatment was carried out 3 replications. The results showed that growth and production were influenced by harvest age and fertilizer level. The nutrient content of sorghum plants of Numbu variety which is influenced by harvest age is only BK, BO and SK, the contents of PK and LK, are not affected by harvest age. The highest BK content in treatment U3 (22.55%). The highest BO content in U3 treatment (91.90%). The highest SK content was in treatment U3 (38.56%). The content of PK and SK was significantly influenced by the nitrogen fertilizer (P <0.05), while the content of BK, BO and LK, was not significantly different. The highest PK content in treatment P3 (7.58%). The lowest SK content was P3 treatment (34.78%). These results indicate that the use of nitrogen fertilizers up to 200 kg / ha can increase (P <0.05) crude protein content, and reduce crude fiber content.

Abstract

Kajian penapisan galur-galur padi terhadap serangan patogen tumbuhan merupakan tahapan penting untuk mendapatkan varietas padi unggul tahan penyakit. Tiga puluh empat galur padi dikaji penapisan untuk mengetahui tanggapannya terhadap serangan patogen tumbuhan. Penelitian dilakukan pada lahan persawahan irigasi yang merupakan daerah endemik patogen tersebut. Rancangan penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan 3 blok sebagai ulangan. Pengamatan dilakukan terhadap kerusakan tanaman yang diakibatkan oleh berbagai jenis patogen tumbuhan meliputi bercak nekrotik kecoklatan daun yang diakibatkan oleh  jamur patogen Cercospora oryzae, penyakit blast berupa bercak daun yang berbentuk belah ketupat  di bagian tengah berwarna abu-abu yang diakibatkan oleh jamur patogen Pyricularia oryzae, busuk pelepah daun bendera yang diakibatkan oleh jamur patogen Sarocladium oryzae, bercak daun yang berukuruan sempit berwarna hijau gelap kekuningan sampai coklat yang diakibatkan oleh bakteri patogen Xanthomonas campestris, serta busuk pangkal batang yang disebabkan oleh jamur patogen Sclerotium oryzae. Hasil penelitian menunjukkan bahwa gejala serangan busuk pangkal batang ditemukan pada 34 galur padi Penyakit bercak daun  menyerang hampir semua galur padi, kecuali UGM-F-00005 dan UGM-F-00033. Serangan penyakit blast tidak ditemukan pada beberapa galur yaitu UGM-F-00016, UGM-F-00018, UGM-F-00019, UGM-F-00021, UGM-F-00029 dan UGM-F-33. Penyakit busuk pelepah daun ditemukan hampir semua galur, kecuali  galur UGM-F-00028 dan UGM-F-00029.

Abstract

Kajian penapisan padi terhadap serangan organisma pengganggu tanaman merupakan tahapan penting untuk mendapatkan varietas unggul. Tiga puluh empat aksesi padi dilakukan penapisan untuk mengetahui tanggapannya terhadap serangan hama serangga dan nematoda parasit tanaman. Penelitian dilakukan pada lahan persawahan irigasi yang merupakan daerah endemik kedua golongan hama tersebut. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 3 blok sebagai ulangan. Pengamatan berupa gejala kerusakan tanaman yang diakibatkan oleh berbagai jenis hama serangga dan nematoda parasit tanaman. Hasil penelitian menunjukkan serangan hama walang sangit  pada semua aksesi padi yang diuji. Serangan wereng hijau ditemukan pada aksesi no UGM-F-00004 dan UGM-F-00008, sedangkan serangan penggerek batang hanya ditemukan pada aksesi nomor UGM-F-00005 dan UGM-F-00006. Jenis nematoda parasit tanaman yang ditemukan adalah Meloidogyne graminicola, Hirsmaniella oryzae, Helicotylenchus sp., dan Criconemoides sp. dengan tingkat populasi yang beragam. Aksesi nomor UGM-F-00028 paling rentan terhadap serangan nematoda M.graminicola. dengan populasi tertinggi > 600 nematoda per 100 g tanah dan 900 nematoda per 5 g akar.

Abstract

The purpose of this research is to know the effect of age on reproductive performance of Crossbreed goat etawah in Kulon Progo regency in a productive age. The object of this research is the respondents and their Goats as the research material that is the Doe Crossbreed goat Etawah which is 1.5 until 3 years old (poel 2 to 3 pairs). The method used in this research is a survey through an interview using a questionnaire. Location is determined by population level that is population high, middle and low in Sub Girimulyo and Samigaluh. The observed reproduction performance was litter size, postpartum estrus, postpartum mating, service per conception and lambing interval. The research data is conducted by Independent T-test. The results showed that the litter size, postpartum estrus, postpartum mating, service per conception and lambing interval were not significantly different between the age of poel 2 and poel 3. The litter size poel 2 and 3 were 1.65+0, 54 and 1.72±0.55. Postpartum estrus goat poel 2 is 4.37±1.23 and goat poel 3 is 4.46±1.19. Postpartum mating goats poel 2 and 3 are 4.38±1.23 and 4.46±1.19. The number of lambing intervals of crossbreed goat etawah poel 2 and 3 respectively were 9.54±1.35 and 9.60±1.28. Service per conception of crossbreed goat etawah poel 2 equal to 1.28±0.65, poel 3 equal to 1.22±0.55. It can be concluded that the reproductive performance of crossbreed goat etawah at the productive age of 1.5 to 3 years is not affected by age.
