Judul: Pengaruh Wadah Dan Lama Penyimpanan Terhadap Kualitas Tepung Ikan
Abstrak: Suatu penelitian tentang pengaruh jenis wadah dan lama penyimpanan terhadapa kwalitas tepung ikan telah dilakukan penyimpanan terhadap kwalitas tepung ikan telah dilakukan di Laboratorium Ilmu Makanan Ternak Fakultas Peternakan Institut Pertanian Bogor, mulai tanggal 3 November 1980 samapai dengan tanggal 26 Januari 1981. Sebagai materi digunakan dua macam bahan makanan ternak, yaitu tepung ikan Thailand dan tepung ikan lokal (ujung Pandang).

Judul: Mempelajari pengaruh lama penyimpanan limbah pengalengan ikan terhadap mutu tepung dan pelet ikan yang dihasilkan
Abstrak: Salah satu pemanfaatan limbah perikanan sebagai pening- katan konsumsi protein hewani di samping peningkatan produksi perikanan adalah diolah menjadi tepung dan pellet ikan dengan beberapa tingkat penyimpanan. Penelitian ini bertujuan mempe lajari sejauh pengalengan dihasilkan. Perlakuan pada penelitian ini adalah lama penyimpanan dengan lima tingkat penyimpanan (4, 8, 12, 16, dan 20 hari) dengan dua produk yang dihasilkan (tepung dan pellet ikan). Rancangan yang digunakan adalah rancangan acak lengkap dengan pola faktorial 5 x 2 ulangan dua kali sehingga didapatkan 20 satuan percobaan. Hasil analisis menunjukkan bahwa nilai kadar air tepung ikan cendrung meningkat pada hari ke 12, kemudian turun pada har ke 20. Nilai kadar air pellet ikan turun dari hari ke sampai hari ke 20.

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
