Judul: Pengaruh Faktor Manajemen Piutang terhadap Likuiditas dan Profitabilitas Perusahaan Sub Sektor Properti dan Real Estate di Bei
Abstrak: Sektor properti dan real estate merupakan perusahaan yang bergerak dalam bidang penyediaan, penyewaan dan kepemilikan tanah dan bangunan bagi keperluan usaha-usaha sektor yang lain. Peningkatan piutang usaha selama lima tahun menuntut perusahaan untuk memiliki sistem pengelolaan piutang yang baik. Penelitian ini bertujuan : (1) Menganalisis faktor manajemen piutang, likuiditas dan profitabilitas perusahaan sub sektor properti dan real estate di BEI, (2) Menganalisis pengaruh faktor manajemen piutang terhadap likuiditas dan profitabilitas perusahaan. Data yang digunakan data sekunder periode 2010-2014. Untuk melihat besarnya pengaruh faktor manajemen piutang terhadap likuiditas dan profitabilitas, digunakan alat analisis SEM dengan peubah Receivable Turn Over, Average Collection Period, Current Ratio, Quick Ratio, Retun on Asset dan Return on Equity. Hasil analisis faktor manajemen piutang berpengaruh positif tidak nyata terhadap likuiditas dan berpengaruh negatif nyata terhadap profitabilitas.

Judul: Analisis Pengaruh Manajemen Piutang Terhadap Likuiditas dan Profitabilitas Perusahaan (Studi Kasus Pada PT XYZ Indonesia)
Abstrak: PT XYZ mengalami peningkatan penjualan yang berdampak kepada peningkatan piutangnya. Apabila piutang tidak dibayarkan tepat waktu maka akan menganggu keuangan perusahaan. Dalam mengelola manajemen piutang tersebut, likuiditas dan profitabilitas juga perlu diperhatikan. Tujuan dari penelitian ini adalah (1) Mengidentifikasi pengelolaan manajemen piutang premi dilihat dari perputaran piutang dan periode penagihan rata-rata pada perusahan PT XYZ Indonesia (2) Menganalisis pengaruh manajemen piutang terhadap likuiditas perusahaan pada PT XYZ Indonesia (3) Menganalisis pengaruh manajemen piutang terhadap profitabilitas perusahaan pada PT XYZ Indonesia (4) Mengidentifikasi pengaruh likuiditas terhadap profitabilitas perusahaan pada PT XYZ Indonesia. Penelitian ini menggunakan data perusahaan tahun 2007-2014 yang dianalisis dengan menggunakan SEM. PP dan PRR merupakan faktor loading dari laten MP. RL dan RK merupakan faktor loading dari laten LIQUID. ROA dan ROE merupakan faktor loading dari laten PROFIT. Hasil analisis faktor manajemen piutang terhadap likuiditas berpengaruh positif signifikan dan berpengaruh negatif signifikan terhadap profitabilitas. Likuiditas berpengaruh positif siginifikan terhadap profitabilitas.

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
