Judul: Hubungan Asupan Zat Gizi, Aktivitas Fisik, dan Status Gizi dengan Kebugaran Anggota UKM Bola Voli IPB.
Abstrak: Pemain olahraga bola voli harus memiliki teknik dasar serta kebugaran tubuh yang baik. Tujuan penelitian ini adalah untuk menganalisis hubungan asupan zat gizi, aktivitas fisik, status gizi, dan tingkat kebugaran anggota UKM Bola Voli IPB. Desain penelitian ini adalah cross sectional. Pengambilan contoh dengan teknik purposive sampling berjumlah 33 anggota UKM Bola Voli IPB. Parameter yang diukur adalah kecukupan energi dan zat gizi, aktivitas fisik, status gizi, dan kebugaran tubuh yang diukur dengan VO2 max, persen lemak tubuh, dan wall sit test. Tingkat kecukupan energi, protein, lemak, dan karbohidrat sebagian besar contoh termasuk ke dalam kategori defisit. Hasil penelitian menunjukkan terdapat hubungan positif antara kecukupan energi dengan VO2 max (p= 0.001, r=0.441), protein dengan VO2 max (p= 0.030, r=0.378), dan karbohidrat dengan VO2 max (p= 0.007, r=0.460). Terdapat hubungan negatif antara tingkat kecukupan energi dengan persen lemak tubuh (p= 0.001, r=-0.539), protein dengan persen lemak tubuh (p= 0.001, r=-0.559), dan karbohidrat dengan persen lemak tubuh (p= 0.001, r=-0.551). Terdapat hubungan positif antara status gizi dengan persen lemak tubuh (p= 0.000, r=0.057). Tidak terdapat hubungan antara kecukupan energi dan zat gizi, aktivitas fisik, dan status gizi dengan hasil tes wall sit (p>0.05).

Judul: Pengetahuan Gizi Atlet dan Pelatih, Asupan Gizi, dan Tingkat Kebugaran Atlet Sepak Bola Bhayangkara FC
Abstrak: Sepak bola merupakan salah satu olahraga yang populer di dunia. Tujuan penelitian ini adalah untuk menganalisis hubungan antara asupan gizi dan pengetahuan gizi atlet dengan tingkat kebugaran atlet sepak bola Bhayangkara FC. Desain penelitian ini adalah cross-sectional study dengan jumlah subjek yang dianalisis sebanyak 18 orang yang bersedia mengikuti penelitian dengan menandatangani informed consent dan tidak mengikuti seleksi atau latihan Tim Nasional. Hasil penelitian menunjukkan bahwa rata-rata tingkat kecukupan energi defisit ringan serta tingkat kecukupan protein dan lemak defisit berat. Rata-rata nilai VO2 max subjek sebesar 52.7 ± 2.45 ml/kg/menit. Terdapat hubungan yang signifikan antara asupan energi dengan tingkat kebugaran (p=0.032, r=0.506). Hasil uji menunjukkan tidak adanya hubungan signifikan antara asupan lemak, protein, karbohidrat, dan tingkat pengetahuan gizi atlet terhadap tingkat kebugaran atlet.

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
