This research was conducted to determine the effect of leaf extract katuk (EDK), lemurufish oil (MIL) and vitamin E as a substitute for a commercial feed supplement on performance and quality of broiler chickens. The total of 195 birds were used as objects in this study.  Design research used Completely Randomized Design (CRD) with 13 treatments and 3 replications. Each test consisted of five broiler chickens. The data obtained were analyzed according to the design used and Test DMRT (Duncan Multiple Range Test) to examine differences in treatment effect. The results showed that the use katuk leaf extract, lemuru oil, and vitamin E  did not differ significantly (P>0.05) on ration consumption, weight gain, feed conversion and internal organ weight of broiler chickens.  In contrast, there were highly significant differences (P<0.01) on serum, cholesterol level, triglyceride, LDL cholesterol and HDL cholesterol.  Similarly, feeding sauropus androgynus extract and lemuru fish oil plus vitamin E are highly significantly (P <0.01) affected weat cholesterol, fant and protein.

Abstract. Praptosuwiryo TNg. 2017. Spore germination and early gametophyte development of Platycerium wandae (Polypodiaceae) from Papua,. Studies on gametophyte development in ferns are very important, as the data generated is often useful for supporting taxa delimitation in ferns and fern-allies. This data is also very important for understanding the ecology, reproductive biology, evolution and distribution of ferns. The study reported here aimed to develop a deeper understand of morphogenesis in the fern Platycerium wandae Racib. by investigating the process of spore germination and early gametophyte development of the species on natural media. Fresh spores of P. wandae were germinated in a mixed media consisting of minced roots of Cyathea contaminans and charcoaled rice hulls (1: 1) under green house condition. Spores of P. wandae are monolete, ellipsoid, nonchlorophyllous, dark brown, and lacking perine. Spores germinated between 7 to 14 days after sowing (DAS). Spore germination of P. wandae is of the Vittaria-type and the prothallial development is of the Aspidium-type, characterized by early development of unicelullar trichomes (30-40 DAS). Only unisexual gametophytes were observed at 60-80 DAS. New data is provided concerning the morphogenesis of P. wandae from Papua, Indonesia, on natural media. The findings are relevant to reproductive biology, would contribute to establish an efficient ex situ propagation strategies for the conservation of epiphyitic ferns and to facilitate further in situ studies of gametophyte ecology.

Abstract. Setianto J, Sutriyono, Prakoso H, Zain B, Adwiyansyah R, Amrullah AHK. 2019. Short Communication: Phenotypic diversity of male Burgo chicken from Bengkulu, Indonesia. Biodiversitas 20: 532-536. Burgo chicken is the result of a crossbreed of Red Junglefowl (Gallus gallus gallus) with Kampung chicken (Gallus domestica). This study aimed to describe the diversity of colors found in male Burgo chickens. The study was conducted in the city of Bengkulu, Indonesia. The method used in this study was a direct observation of the 50 male chickens on the breeders. The breeders belonging to the Burgo chicken community were determined by random sampling method. The breeders who did not join the community were determined by the snowball sampling method. This method was carried out because the presence of breeders who keep Burgo chickens was unknown. The data in this study consisted of the color of chest feathers, neck feathers, wing feathers, tail feathers, saddle feathers, and the number of wing and tail feathers. The data obtained were analyzed descriptively. The number of colors ranges 4 to 11 with the high diversity is mainly found on the feathers of the chest, neck and, saddle.

This study aimed to determine the effect of tofu waste as a feed mixture to the growth of earthworm Pheretima sp. This research was conducted in Bengkulu City and Animal Husbandry Laboratory of Bengkulu University. This research used method of Completely Randomized Design with 4 treatments and 5 replicates: (P1) = Rice husk 50% + Feces of cow 50% + (0% tofu waste), (P2) = Rice husk 50% + Cow feces 45% + (5% tofu waste), (P3) = Rice husk 50% + Cow feces 40% + (10% tofu waste), (P4) = Rice husk 50% + Cow feces 35% + (15% tofu waste). The result of this research showed that the feeding of mixed ration with the stofu waste worm in Pheretima sp was very significant (P <0.01) to the growth of Pheretima sp earthworm weight and significantly affected (P <0.01) on the offsprings weight on each maintenance unit, and was significantly different (P <0.05) on the average of offsprings body weight per head.Key words: tofu waste, mixture of feed, growth, earthworm Pheretima sp. ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh pemberian ampas tahu sebagai campuran pakan terhadap pertumbuhan cacing tanah Pheretima sp. Lokasi penelitian ini dilaksanakan di Kota Bengkulu dan Laboratorium Peternakan Universitas Bengkulu. Penelitian ini menggunakan metotede Rancangan Acak Lengakap (RAL) dengan 4 perlakauan serta 5 ulangan: (P1) = Sekam padi 50% + Feses sapi 50% + (0% ampas tahu), (P2) = Sekam padi 50%+Feses sapi 45% + (5% ampastahu), (P3) = Sekam padi 50% + Feses sapi 40% + (10% ampas tahu), (P4) = Sekam padi 50% + Feses sapi 35% + (15% ampas tahu). Hasil dari penelitian ini menunjukan bahwa pemberian pakan campuran ampas tahu pada media cacing tanah Pheretima sp berpengaruh sangat nyata (P<0,01) terhap pertumbuhan bobot induk cacing tanah Pheretima sp dan berpengaruh sangat nyata (P<0,01) terhadap bobot badan anak per unit pemeliharaan serta berbeda nyata (P<0,05) terhadap rataan bobot badan anak per ekor.Kata kunci: ampas tahu, campuran pakan, pertumbuhan, cacing tanah Pheretima sp.

Perusahaan peternakan ayam broiler di Provinsi Bengkulu telah menjadi andalan dalam subsektor peternakan di mana perkembangan usaha ini memberikan kontribusi nyata dalam pembangunan peternakan dan memiliki nilai strategis khususnya dalam upaya pemenuhan kebutuhan protein hewani pada masyarakat dan juga berperan dalam peluang kesempatan kerja. Berdirinya perusahaan peternakan di suatu daerah tertentu akan berpengaruh terhadap kondisi kehidupan sosial ekonomi di lokasi perusahaan seperti di Kecamatan Sukaraja tersebut. Penelitian ini bertujuan untuk menentukan tingkat kepuasan aspek sosial ekonomi dan lingkungan pada perusahaan peternakan ayam broiler Unggas Jaya. Metode penelitian yang digunakan adalah metode deskriptif kualitatif dan variabel yang diamati meliputi identitas responden, keadaan sosial ekonomi dan lingkungan. Hasil penelitian menunjukkan bahwa atribut yang memiliki tingkat kepentingan tertinggi namun kinerjanya rendah berada pada insentif yang diterima, tingkat kesesuaian terendah berada pada biaya kebutuhan hidup, aspek sosial yang memiliki tingkat kepuasan rendah pada atribut pengalaman dalam beternak, atribut biaya kebutuhan hidup pada aspek ekonomi masih memiliki nilai kepuasan yang rendah dan pada aspek lingkungan yang memiliki nilai kepuasan rendah pada atribut penanganan pakan, sehingga nilai yang kepuasan sebesar 81,75% berada pada skala sangat puas, penilaian masyarakat disekitar perusahaan peternakan tidak menimbulkan dampak negatif terhadap lingkungan.Kata Kunci : kepuasan, aspek sosial ekonomi, aspek lingkungan
