Judul: ^aPengaruh pengalaman berinvestasi terhadap literasi keuangan dan keputusan investasi
Abstrak: Investor adalah orang yang sangat berperan aktif dalam kegiatan pasar modal. Investor yang memiliki banyak pengalaman berinvestasi menandakan bahwa investor tersebut memiliki kemampuan mengambil keputusan dalam bertransaksi yang lebih baik jika dibandingkan dengan investor yang kurang berpengalaman. Adanya kenaikan jumlah Sub Rekening Efek harus didukung dengan seberapa besar tingkat literasi keuangan seorang investor dari waktu ke waktu dalam mengambil sebuah keputusan investasi agar dapat mengelola dananya secara bijak dan tepat. Tujuan yang ingin dicapai dalam penelitian ini adalah menganalisis tingkat literasi keuangan investor, menganalisis pengaruh pengalaman berinvestasi terhadap literasi keuangan investor dan menganalisis pengaruh literasi keuangan investor terhadap keputusan investasi. Data primer adalah penyebaran kuesioner terhadap investor. Metode sampel yang digunakan adalah purposive sampling. Analisis data dilakukan dengan metode deskriptif, uji validitas, uji reliabilitas dan regresi linear sederhana. Hasil penelitian menunjukkan bahwa sebagian besar literasi keuangan investor berada diatas ratarata (mean). Pengalaman berinvestasi berpengaruh signifikan terhadap literasi keuangan investor karena semakin lama pengalaman berinvestasi, maka semakin tinggi pula literasi keuangan investor. Literasi keuangan investor tidak berpengaruh signifikan terhadap keputusan investasi karena jika literasi mengalami peningkatan, maka tidak serta merta keputusan investasi semakin tinggi pula.

Judul: Pengaruh Literasi Keuangan, Overconfidence, dan Risk Tolerance terhadap Keputusan Investasi Produk Pasar Modal
Abstrak: Investasi dipasar modal menjanjikan pengembalian yang besar. Pasar modal memberikan kesempatan kepada investor untuk memilih produk pasar modal yang diperdagangkan. Tingkat literasi keuangan investor dalam mengambil keputusan investasi berperan penting agar investor dapat mengelola dana secara bijak dan tepat. Dalam berinvestasi terdapat faktor psikologis yang mempengaruhi keputusan dalam berinvestasi, yaitu overconfidence dan risk tolerance. Penelitian ini bertujuan untuk menganalisis pengaruh literasi keuangandan pengaruh perilaku keuangan terhadap keputusan invetasi produk pasar modal terhadap keputusan investasi produk pasar modal. Data primer adalah penyebaran kuesioner kepada investor. Penelitian ini menggunakan alat analisis SEM PLS. Hasil penelitian menunjukan bahwa variabel literasi keuangan tidak berpengaruh terhadap keputusan investasi, sedangkan variabel overconfidence dan risk tolerance berpengaruh positif signifikan terhadap keputusan investasi.

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
