Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh rasio leverage, pertumbuhan penjualan dan ukuran perusahaan terhadap return on investment pada perusahaan sub sektor plastik dan kemasan yang terdaftar di Bursa Efek Indonesia periode tahun 2013-2016. Dalam penelitian ini, rasio leverage diukur menggunakan Debt to Equity Ratio (DER), Degree of Financial Leverage (DFL), Sales Growth (SG) dan Firm’s Size (Size). Penelitian ini menggunakan data sekunder dan metode penarikan sampel dengan purposive sampling. Metode analisis yang digunakan yaitu secara statistik yang terdiri dari statistik deskriptif dan inferensial dengan menggunakan analisis regresi linier berganda, uji asumsi klasik, dan uji hipotesis dengan bantuan software Statistical Product and Service Solution (SPSS) versi 20.0. Hasil penelitian menunjukan bahwa koefisien determinasi (R square) dalam penelitian ini sebesar 0,531 atau 53,1%. Sedangkan sisanya dipengaruhi oleh variabel lain. Pengujian hipotesis menggunakan uji F menunjukkan bahwa F hitung > F tabel (4,217 > 2,14) dengan nilai signifikansi 0,005 < 0,05. Artinya DFL, SG dan Firm’s Size secara simultan berpengaruh positif signifikan terhadap return on investment, sedangkan pengujian hipotesis menggunakan uji t menunjukkan bahwa nilai debt to equity ratio (-2,068 < 1,607 < 2,068), nilai degree of financial leverage (-2,068 < 0,763 < 2,068), nilai sales growth (-2,068 < 0,583 < 2,068) dan nilai firm’s size (-2,068 < -1,577 < 2,068) dengan –t tabel < t hitung < t tabel dan nilai signifikan > 0,05 yang artinya tidak berpengaruh signifikan terhadap return on investment. Kata Kunci:  Debt to Equity Ratio (DER), Degree of Financial Leverage (DFL),  Sales Growth (SG), Firm’s Size (Size), Return On Investment (ROI)

Abstract

Pregelatinized cassava star ch (PCS) is a physically modified starch. The purposes of the study were to improve functionality of PCS with making coprocess composed of PCS and methylcellulose (MC) by proportionally variation, which are 2:1, 3:1, and 4:1, as well as to applied co-processed excipient that could retard the drug release as coating material of theophylline tablet. Coprocessed excipient were characterized in terms of morphology, particle size distribution, compressibility index, flow rate and angle of repose, thermal analysis, hygroscopicity, gel strength, swelling test, and moiety analysis. Theophylline tablet that coated by PCS, MC, and co-processed PCSMC ratio (4:1) characterized and in vitro drug release were made in chloride medium of pH 1,2 and phosphate medium of pH 7,2. The characterization result of co-processed PCS-MC showed the improvement of functionality from PCS and synergism PCS with MC. Meanwhile, the result of in vitro drug release showed theophylline tablet that coated by MC 1%, co-processed PCS-MC (4:1) 4% and 2% could retard the drug release in both medium.

Abstract

Coating is one of the effective methods used in controlled release dosage form. Lots of variety in the form of a hydrophilic polymer excipient that is used to control the drug release many polymers that can be used for coating purposes, but only a few have been known to serve as a polymeric coating which functions to control the rate of drug release Pregelatinized cassava starch (PCS) is a physically modified starch.

Abstract

Indonesia is a maritime country because it has a very wide geographical condition of the ocean with more than 17,000 islands. Ocean tides are the result of gravitational attraction and centrifugal effects, namely the push towards the outside of the center of rotation. There are two ways to determine the value of tides, the first is to measure directly in the field using a tide gauge or using a numerical modeling program. Therefore, this study intends to compare field data using the ioc-sealevelmonitoring website with tide prediction data using the Naotide program where the data collection point is at the tide station in Cilacap Regency, West Java, Indonesia. This research will produce tidal constituent data from the data and will calculate the RMSE (Root Mead Square Error) value and the correlation coefficient. Mead Square Error) and correlation coefficient of the data. The results show that the two variables can be said to be suitable as evidenced by the RMSE value which is close to 0 (zero) and the correlation coefficient which is in the range of 0.90 - 1.00 which means the correlation value is very high and reliable.

Abstract

Flavonoids are one of the compounds that are effective as antioxidants and function to protect against exposure to free radicals. One of the plants that contain flavonoid compounds is the leaves of Graptophyllum pictum L. Griff Var. viride. This study was conducted to determine phytochemical screening, total flavonoids, total phenolics, and antioxidant activity analysis contained in the leaves of Graptophyllum pictum L.Griff Var. viride. This type of research is an experimental exploratory research. Extraction by multistage maceration using three solvents namely N-Hexan, ethyl acetate and 96% ethanol, antioxidant activity test with DPPH method, total flavonoid test using aluminum chloride colorimetric assay method, and total ph enol test using Folin-Ciocalteu method from Graptophyllum pictum L .Griff Var. viride leaves. The results of extraction with 400 g of Graptophyllum pictum L. Griff Var. viride leaf simplicia with N-Hexan, ethyl acetate, 96% ethanol respectively produced 4.5 g, 3.9 g, and 41.5 g of thick extract. The IC 50 values of N-Hexan, ethyl acetate, and ethanol extracts were 317.70 µg/mL, 227.30 µg/mL and 231.86 µg/mL, respectively. The total flavonoid content of N-Hexan, ethyl acetate, and ethanol extracts were 8.03; 55.52; 25.61mg quercetin equivalents/g extract, respectively. The total phenol content of N-Hexan, ethyl acetate, and ethanol extracts were 19,164; 16,135; 27,251 mg GAE/g extract, respectively.
