Judul: Kualitas tidur mahasiswa Institut Pertanian Bogor.
Abstrak: Tidur merupakan aktivitas penting dalam kehidupan manusia. Tidur adalah keadaan di mana otak tidak mengolah informasi dari neuron sensorik dan tidak memberi perintah ke neuron motorik. Kualitas tidur seseorang dapat ditentukan dengan metode Pittsburgh Sleep Quality Index (PSQI). Kualitas tidur terdiri atas tujuh komponen, yaitu: kualitas tidur subyektif, tidur laten, lama tidur, efisiensi tidur, gangguan tidur, pemakaian obat tidur dan disfungsi siang hari. Ketujuh komponen dikuantifikasi dan total skor yang didapat disebut nilai PSQI. Jika seseorang mempunyai nilai PSQI ≤ 5 maka ia mempunyai kualitas tidur baik, dan jika seseorang mempunyai nilai PSQI > 5 maka ia mempunyai kualitas tidur yang buruk. Tujuan penelitian ini untuk mengetahui kualitas tidur mahasiswa Institut Pertanian Bogor. Proporsi mahasiswa S1 laki-laki yang berkualitas tidur baik (15.48%) sama dengan proporsi mahasiswa S1 perempuan yang berkualitas tidur baik (15.36%). Begitu juga proporsi mahasiswa pascasarjana laki-laki dan perempuan yang berkualitas tidur baik adalah sama yaitu (25% dan 28.13%). Tanpa memandang jenis kelamin, proporsi mahasiswa S1 yang berkualitas tidur baik adalah 15.41%, sedangkan proporsi mahasiswa pascasarjana yang berkualitas tidur baik adalah 27.26%.

Abstrak: Sleep is an important activity undertaken by humans and spend nearly a third of the human life time. Sleep is a condition in which the brain does not process information from sensory neurons and does not give orders to the motor neurons. Sleep quality of person can be determined using the Pittsburgh Sleep Quality Index (PSQI). The data of this research were obtained by giving questionnaires contain personal data and questions about the components of sleep quality during the past month There are seven components of sleep quality, subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The purpose of this study was to determine the sleep quality of employee of Bogor Agricultural University. Value of PSQI obtained from the calculation of the seven components, if someone has a value of PSQI < 5 then he has good sleep quality, and if someone has value of PSQI >5 then he has poor sleep quality. The purpose of this study is to determine the sleep quality of employee of Bogor Agricultural University. The proportion of male employee who had good quality sleep were equal to the proportion of female who had good quality sleep. As much as 48.27% of the total sample of employees have good sleep quality. As much as 62,5% of employees over the age of 51 years have poor sleep quality.

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
