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: Pengaruh Motivasi dan Perilaku Pembaca Terhadap Keputusan Dosen IPB Dalam Membaca Media Online
Abstrak: Saat ini industri media cetak mengalami masalah serius. Perkembangan teknologi di bidang komunikasi dan informasi telah menyebabkan media online tumbuh dengan cepat menggantikan fungsi media cetak. Pertumbuhan media online mendorong industri media cetak mengubah produk mereka menjadi versi online, bahkan beberapa perusahaan berhenti cetak dan tidak berproduksi lagi. Penelitian ini bertujuan (1) menganalisis pengaruh motivasi pembaca terhadap keputusan membaca media online (2) menganalisis pengaruh motivasi pembaca terhadap perilaku membaca media cetak (3) menganalisis pengaruh motivasi pembaca terhadap perilaku membaca media online (4) menganalisis pengaruh perilaku membaca media cetak terhadap keputusan membaca media online (5) menganalisis pengaruh perilaku membaca media online terhadap keputusan membaca media online. Penelitian ini dilakukan di Institut Pertanian Bogor terhadap 92 dosen IPB sebagai responden penelitian. Teknik proportional stratified random sampling digunakan dalam penelitian ini. Structural Equation Model (SEM) berbasis Smart PLS versi 2.0 dengan 4 variabel laten yang terdiri dari motivasi pembaca, perilaku membaca media cetak, perilaku membaca media online dan keputusan membaca media online digunakan dalam penelitian ini untuk menganalisis data. Hasil penelitian menunjukkan bahwa (1) motivasi pembaca mempunyai pengaruh signifikan terhadap keputusan membaca media online (2) motivasi pembaca mempunyai pengaruh signifikan terhadap perilaku membaca media cetak (3) motivasi pembaca mempunyai pengaruh signifikan terhadap perilaku membaca media online (4) perilaku membaca media cetak tidak mempunyai pengaruh terhadap keputusan membaca media online (5) perilaku membaca media online tidak mempunyai pengaruh terhadap keputusan membaca media online.

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
