Judul: Pengaruh bobot telur tetas terhadap fertilitas, daya tetas, bobot tetas dan pertumbuhan anak ayam broiler
Abstrak: Penelitian ini dilakukan di dua tempat yaitu untuk penetasan dilakukan di Bagian Penetasan perusahaan penetasan PT. PENTA FARM Boger dan untuk pemeliharaan anak ayam dilakukan di Laboratorium Unggas Jurusan Ilmu Nutrisi dan Makai,an Ternak, Fakultas Peternakan, Institut Pertanian Bogor, selama 10 minggu yaitu mulai tanggal 12 Maret sampai dengan 21 Mai 1986. Tujuan penelitian adalah untuk mengetahui sampai berapa jauh pengaruh bobot telur terhadap fertilitas, daya tetas, saleble chicks, bobot tetas dan pertumbuhan anak ayam broiler. Pada penelitian ini digunakan 1200 butir telur tetas dari ayam broiler strain Hybro yang dibagi atas empat kelompok berat yaitu berat [ 50 ; 55 gram/butir,[ 55 ; 60] gram/butir,[ 60 ; 65]gram/butir dan [65 ; 70] gram/butir, masing-masing sebanyak 400 butir. Setiap perlakuan diulang lima kali, masing-masing 80 butir. Anak ayam yang menetas dari masing-masing ulangan diambil secara acak sebanyak 10 ekor dan dipelihara dalam kandang batere berukuran 1 x 1 x 0,75 meter. Ransum yang dJgunakan adalah ransum komersiel berbentuk cramble produksi Cargill Indonesia.

Judul: Pengaruh dua ketinggian tempat yang berbeda terhadap daya tetas, waktu tetas, kualitas kerabang & bobot tetas pada telur ayam broiler
Abstrak: Penelitian dilakukan pada dua lokasi pembibitan ayam yaitu Jimmy Farm, Gadog, Cipanas, Cianjur, dan Satwa Farm, Setia Bojonggede, Parung, Bogor, selama delapan minggu mulai 10 Oktober sampai dengan 10 Desember 1987. Tujuan penelitian adalah mengetahui sampai. berapa Jauh pengaruh ketinggian tempat terhadap daya tetas, waktu tetas, kualitas kerabang, dan bobot tetas pada Telur Broiler. Ayam Pada penelitian ini digunakan 720 butir telur Broiler strain 52-57 gram. Arbor Acres dengan kisaran tetas bobot tetas Telur berasal dari Jimmy Farm (360 butir) dan Setia Satwa Farm (360 butir). Telur ditetaskan pada 100°, kali Rh 50 60 persen, pemutaran telu = per suhu dilakukan tujuh hari dan mesin tetas yang digunakan Still Air Type yang berkapasitas 400 butir terdiri dari dua ruangan. Rancangan percobaan digunakan Rancangan Acak dengan pola faktorial 2 x 2. (T) dan faktor kedua Lengkap Faktor Pertama tempat asal adalah lokasi penetasan (P) DAN telur

Judul: Systematics of Desmos (Annonaceae) in Malesia
Abstrak: Desmos is a woody climbing genus of Annonaceae which has been widely used as traditional medicine in several countries such as China, Indo-China, Thailand, and Peninsular Malaysia to treat dysentery, vertigo, fever, and postpartum. Phylogenetic studies on Desmos showed a close relationship between Desmos and Dasymaschalon. They share similar moniliform monocarpic fruits, but their flowers are different. It has been debated among Annonaceae researchers whether both genera should be treated as the same or distinct genus. Therefore, investigation on the taxonomic delimitation of Desmos species and Dasymaschalon will be necessary. Plastid genome (plastome) identification, leaf epidermal section of Desmos species and Dasymaschalon species, a taxonomic revision of Desmos in Malesia using morphological data, the spatial distribution of Desmos species in Malesia, and morphological and genetic variation in Desmos chinensis population using ISSR marker were used to investigate taxonomic delimitation of Desmos. Plastome study of Desmos chinensis and Dasymaschalon dasymaschalum was carried out to determine the origin, evolution, phylogenomics, and identify marker candidates for Desmos and Dasymaschalon or with other genera in Annonaceae. We discovered that the plastome of Desmos chinensis was circular with the size of 167,677 bp (smaller than Dasymaschalon dasymaschalum), consist of 111 genes, including 78 protein-coding genes, 29 transfer RNAs, and 4 ribosomal RNAs. The plastome showed a typical quadripartite structure, i.e., large single copy (LSC), small single copy (SSC), and two inverted repeats (IRs). The plastome of Dasymaschalon dasymaschalum was 191,488 bp in length, which also exhibited a typical quadripartite structure (LSC, SSC, and two IRs). Desmos chinensis and Dasymaschalon dasymaschalum showed different copies of accD, ndhD, ndhF, rps18, and ycf2. Protein coding genes of rpoB, rpoC1, rbcL, matK, rpl32, infA, and rpl36 were identified based on nucleotide diversity, sequence variability, and parsimony-informative sites. The genes are defined as molecular marker candidates of plastome for phylogenetic, barcoding, and population genetic research. We predicted that Desmos chinensis and Dasymaschalon dasymaschalum separated at ca. 64 million years ago during the Paleocene. Leaf anatomical feature study was carried to support the taxonomic delimitation of interspecific Desmos and intergeneric of Desmos and Dasymaschalon. Leaf anatomy in the paradermal section of 20 taxa (12 species of Desmos, eight species of Dasymaschalon) have been carried out. According to the leaf epidermal section, Desmos and Dasymaschalon are two distinct genera mainly distinguished based on the anticlinal wall undulation of epidermal cells and supported by variation of the crystal type and size. The anticlinal wall undulation of Desmos was almost straight to slightly wavy and never sinuous; meanwhile, Dasymaschalon varies from almost straight to deeply sinusoid. The crystals of Desmos consist of rhombohedral, druse type A, and druse type B crystals, whereas Dasymaschalon has prism, druse type A, druse type B, and druse type C crystals. The recent taxonomic revision using the morphological data was mainly based on the examination of about 1374 specimens from BO, L, WAN, ANDA, SING, SAN, K, P, HUH herbaria. The Desmos species in Malesia consists of eight species: D. acutus, D. chinensis, D. chryseus, D. dunalii, D. pedunculosus, D. subbiglandulosus, two new records: D. lawii and D. macrocarpus, and one
