Judul: Motivasi, sikap, dan perilaku membaca ebook mahasiswa program S1 IPB
Abstrak: This study aimed to analyze the motivation, attitude, and reading behavior of electronic-book (ebook) among undergraduate students at Bogor Agricultural University. This research involved 100 undergraduate students from each faculty who were selected conveniencely. Data was collected through the questionaire. The result showed that the samples have a high level of motivation to use ebook and agree use ebook because attributes of price, gateway to access, type of book, content, and simpleness. Samples have a positive attitude toward attributes of ebook. The frequency of reading samples is once a week with duration of reading is 1-2 hours. The result showed there is a positive significant correlation between age and length of study within motivation and attitude, as well as motivation and frequency. On the other side, the negative correlation between Grade Point Average and attitude toward an ebook. Moreover, there is a positive and very significant correlation between motivation and attitude toward duration of reading an ebook.

Judul: Analisis faktor-faktor yang berpengaruh terhadap sikap dan perilaku membeli buku bajakan pada mahasiswa IPB
Abstrak: The aim of research is to analyse factors which influence IPB students attitudes and buying behaviour of piracy book. Research methode using cross sectional study design. Data aggregation along Mei 2009. Data was taken from 200 sample girls and boys with equilibrate. The way of taking out sample from every faculty appropiete with proportional sampling. Obtainable data is primery data and secondary data. Tabulation and analysis data by description and statistic test (mann withney/ T test, double linier regression with backward method and logistic regression test with entered method). Almost samples are readed book and mostly they buy a book for the last three months. Almost of them is had knowledge with average value. For the samples attitude that quite netral about book piracy. Their basic reason that piracy book is cheaper than the original. From the result can show the factors that influencing attitude concerning book piracy is amount of ages, allocation of money, information resources, and knowledge. The factor that influencing behavior buying of piracy book is attitude.

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
