Judul: Analisis kelayakan finansial unit usaha pakan ayam broiler pada koperasi peternak unggas kujang lestari, Kabupaten Bogor
Abstrak: Dari informasi lapangan tim Pusat tudi Pembangunan IPB (1995) diketahui bahwa harga pakan ditentukan oleh Gabungan Pengusaha Makanan Ternak Indonesia (GMTI) dengan sistem kartel. Penentuan harga dengan sistem kartel ini menyebabkan harga pakan yang dibayar oleh peternak rakyat lebih tinggi daripada harga pakan yang dibayar oleh peternakan besar yang berafiliasi dengan pabrik pakan.

Judul: Analisis Kelayakan Usaha Peternakan Ayam Broiler Di Desa Lulut Kecamatan Klapanunggal Kabupaten Bogor
Abstrak: Usaha peternakan yang banyak diminati adalah peternakan ayam broiler karena memiliki permintaan yang tinggi. Kabupaten Bogor merupakan salah satu daerah sentra produksi daging ayam broiler di Jawa Barat. Penelitian ini bertujuan untuk (1) menganalisis kelayakan usaha ternak ayam broiler ditinjau dari aspek non finansial seperti aspek pasar, aspek teknis, aspek manajemen dan hukum, aspek sosial dan budaya serta aspek lingkungan (2) menganalisis kelayakan usaha ternak ayam broiler ditinjau dari aspek finansial (3) menganalisis tingkat kepekaan (sensitivitas) kelayakan usaha peternakan ayam broiler. Penelitian ini dilakukan pada bulan November sampai dengan Desember 2015 dengan menggunakan data primer dan sekunder. Data primer diperoleh dari wawancara langsung dengan pemilik peternakan dan data sekunder melalui internet dan literatur yang relevan. Adapun analisis yang digunakan yaitu analisis kualitatif dan kuantitatif, dimana analisis kualitatif dilakukan secara deskriptif menggambarkan sistem usaha dan aspek nonfinansial serta analisis kuantitatif yang digunakan yaitu analisis kelayakan finansial. Berdasarkan hasil analisis aspek non finansial dan finansial usaha peternakan ayam broiler layak untuk dilanjutkan, karena dilihat dari nilai NPV sebesar Rp632 149 173, Net B/C sebesar 3.23, IRR sebesar 71.68 persen dan PP sebesar 2.8 tahun, dengan discount rate 6.5 persen. Hasil analisis switching value menunjukkan usaha peternakan ayam broiler sangat sensitif terhadap kenaikan harga pakan sebesar 15.53 persen penurunan harga jual sebesar 47.42 persen, sedangkan kenaikan harga DOC sebesar 65.22 persen pada peternakan ayam broiler ini tidak sensitif.

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
