Judul: Analisis Pengaruh Good Corporate Governance terhadap Kinerja Keuangan dan Harga Saham Perusahaan yang Masuk ke Dalam Pemeringkatan Corporate Governance Perception Index
Abstrak: Good corporate governance (GCG) adalah suatu sistem dan seperangkat peraturan yang mengatur hubungan antara berbagai pihak yang berkepentingan demi tercapainya tujuan perusahaan. Tujuan penelitian ini adalah menguji pengaruh penerapan GCG terhadap kinerja keuangan dan harga saham. Penerapan GCG diproksi dengan skor Corporate Governance Perception Index (CGPI), kinerja keuangan diproksi dengan rasio Tobin’s Q, dan harga saham diproksi dengan harga saham pada penutupan akhir tahun. Sampel yang digunakan pada penelitian ini adalah perusahaan yang terdaftar pada pemeringkatan CGPI dan Bursa Efek Indonesia dari tahun 2007-2011. Berdasarkan hasil uji hipotesis didapatkan bahwa penerapan GCG secara parsial tidak berpengaruh signifikan terhadap variabel kinerja keuangan dikarenakan berdasarkan uji R2 didapatkan hasil bahwa hanya sebesar 8% rasio Tobin’s Q dipengaruhi oleh penerapan GCG sedangkan sisanya dipengaruhi oleh faktor lainnya. Penerapan GCG secara parsial berpengaruh signifikan terhadap variabel harga saham yaitu sebesar 16.2% harga saham dipengaruhi oleh penerapan GCG sedangkan sisanya dipengaruhi oleh faktor lainnya.

Judul: Pengaruh Corporate Governance Terhadap Harga Saham (Studi Kasus Pada Perusahaan Tercatat Indeks KOMPAS100 Tahun 2014-2018)
Abstrak: Praktik good corporate governance memiliki peranan sangat penting dalam mengarahkan dan mengelola suatu perusahaan. Salah satu penyebab krisis keuangan yang dialami Indonesia pada tahun 1998 dan 2008 adalah lemahnya praktik tata kelola suatu perusahaan di Indonesia. Perkembangan praktik tata kelola di Indonesia masih sangat tertinggal dengan negara ASEAN lainnya, berdasarkan hasil penilaian terakhir ASEAN Corporate Governance Scorecard (ACGS) Indonesia berada di peringkat ke 4 dari 6 negara peserta ACGS. Penelitian terdahulu menyatakan bahwa good corporate governance mempengaruhi harga saham suatu perusahaan. Penguatan corporate governance pada perusahaan akan mengurangi agency problem dan tercipta pengelolaan perusahaan yang transparan, akuntabel, tanggung jawab, independen dan wajar. Hal ini tentu akan menarik minat investor dalam menginvestasikan dananya sehingga akan mempengaruhi harga saham perusahaan tersebut. Harga saham akan berfluktuasi seiring dengan permintaan dari saham tersebut. Penelitian ini bertujuan untuk menganalisis tingkat kepatuhan perusahaan Indeks KOMPAS100 dalam menerapkan dan mengungkapan praktik Good Corporate Governance pada 2014 – 2018 dan menganalisis pengaruh Good Corporate Governance terhadap Harga Saham. Jumlah sampel penelitian adalah 56 perusahaan yang dipilih berdasarkan teknik purposive sampling dengan 3 kriteria. Jenis data yang digunakan data sekunder dari laporan tahunan perusahaan, situs web dan informasi resmi regulator atau perusahaan. Teknik pengolahan data menggunakan analisis data panel dengan bantuan perangkat lunak STATA 16. Hasil penelitian menunjukkan bahwa jumlah Komisaris Independen, return on assets, price to earning ratio dan price to book value memiliki pengaruh yang signifikan terhadap harga saham ke arah positif. Variabel jumlah rapat Dewan Komisaris, jumlah Direksi, jumlah rapat Direksi, pendidikan/pelatihan sekretaris perusahaan dan earning per share memiliki pengaruh positif namun tidak signifikan. Hasil uji simultan menunjukkan adanya pengaruh positif signifikan dari sembilan variabel independen terhadap harga saham. Hasil pengujian koefisien determinan menunjukkan besarnya adjusted R-square adalah 0.9609 atau 94.81%., Good corporate governance practice plays a very important role to direct and manage a company. One of the causes of the financial crises that Indonesia experienced in 1998 and 2008 was the weak corporate governance practices. The development of governance practices in Indonesia is still lagging behind other ASEAN countries. Based on the results of the latest assessment of the ASEAN Corporate Governance Scorecard (ACGS), Indonesia is in 4th place out of 6 ACGS participating countries. Previous research statef that good corporate governance affects the stock price of a company. Strengthening corporate governance in companies will reduce agency problems and create transparent, accountable, responsible, independent and fair company management. It will certainly attract investors to invest their funds, thus, it will affect the company's stock price. Share prices will fluctuate in line with the demand for these shares. This research aimed to analyze the level of compliance of companies with the KOMPAS100 Index in implementing and disclosing Good Corporate Governance practices in 2014-2018 and analyzing the effect of Good Corporate Governance on Stock Prices. The number of research samples were 56 companies selected based on purposive sampling technique with 3 criteria. The type of data used was secondary data from company annual reports, websites and official information of regulators or companies. The data processing technique used panel data analysis with the help of STATA 16 software. The

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
