Judul: Pengaruh Faktor Internal dan Eksternal Terhadap Profitabilitas Unit Usaha Syariah di Indonesia Periode 2014-2018
Abstrak: Profitabilitas merupakan salah satu alat untuk mengukur kinerja keuangan, termasuk di dalamnya Unit Usaha Syariah (UUS). Return on Assets (ROA) merupakan salah satu indikator yang digunakan dalam mengukur profitabilitas. Tujuan dari Penelitian ini adalah untuk menganalisis faktor internal dan eksternal terhadap profitabilitas UUS di Indonesia periode 2014-2018, dengan menganalisa data laporan keuangan seluruh UUS berdasarkan dari Otoritas Jasa Keuangan (OJK) dan Bank Indonesia (BI). Metode yang digunakan pada penelitian ini adalah Vector Error Correction Model (VECM). Hasil penelitian menunjukkan bahwa dalam jangka panjang variabel FDR, dan BOPO signifikan positif terhadap profitabilitas UUS, sedangkan variabel CAR, NPF, inflasi, dan suku bunga juga berpengaruh signifikan negatif.

Judul: Analisis Faktor-Faktor yang Memengaruhi Profitabilitas Bank Umum Syariah dan Unit Usaha Syariah di Indonesia Periode 2012 - 2017
Abstrak: Rasio kinerja profitabilitas BUS dan UUS biasanya diukur dengan Return on Asset (ROA). Return on Asset (ROA) merupakan rasio keuangan yang mengukur kemampuan bank dalam memperoleh keuntungan secara keseluruhan. Pada tahun 2017, ROA BUS dan UUS yang ada di Indonesia mengalami penurunan. Hal ini menunjukkan bahwa kinerja perbankan mengalami penurunan. Tujuan penelitian ini adalah menganalisis faktor-faktor yang memengaruhi profitabilitas BUS dan UUS di Indonesia melalui data bulanan dari Statistik Perbankan Syariah (SPS) OJK dan data dari Bank Indonesia. Metode yang digunakan pada penelitian ini adalah Error Correction Mechanism (ECM). Hasil penelitian menunjukkan bahwa pada model jangka panjang, variabel NPF dan BOPO berpengaruh signifikan negatif terhadap ROA. Pada model jangka pendek, variabel DPK, NPF, BOPO dan BI rate memiliki pengaruh negatif dan signifikan terhadap ROA. Variabel FDR dan inflasi memiliki pengaruh positif signifikan terhadap ROA.

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
