Abstract

This study aims to determine the effect of foreign investment flow, World capital market (MSCI-World Index), rupiah exchange rate against US dollar and country risk (EMBI +) on Indonesia capital market return. The test is done by using multiple linear regression models. The test also uses stationery test data using Augmented Dicky Fuller Test (ADF) method. Then the Classic Assumption Test (Normality Test, Multicollinearity Test, Heteroscedasticity Test, and Autocorrelation Test), Hypothesis Testing includes Partial Test (t-test statistic), Goodness of Fit Test, and simulation test (statistic F test). The test result of this research by using multiple linear regression shows that the variable of foreign investment flows have a positive and significant effect on the return of Indonesian capital market, the variable risk country has no significant negative effect on the return of Indonesian capital market, while the world capital market variable and the rupiah exchange rate against US dollar significantly influence the return of Indonesia capital market.

Abstract

The suitability for papermaking of red meranti (Shorea selanica Blume) wood for three alkaline pulping processes i.e soda, soda-anthraquinone (AQ), and kraft was studied. The fiber morphology and chemical properties were also examined. Cooks were made for 20% (as Na2O) activate alkali. The resulting pulp and paper properties were investigated. The basic density of red meranti was 0.42 g/cm3 and can be classified to be of medium density. The fibre proportion (67.14%) and fibre length (1.07 mm) of red meranti in this study were within the range of tropical hardwoods. The derived values for Runkel ratio, slender ratio, and flexibility coefficient were 0.54, 54.93, and 0.62, respectively. Furthermore, total extractives, lignin, and cellulose contents as well as solubility in 1% NaOH were 5.17%, 31.05%, 45.20%, and 26.02%, respectively. The alkaline pulps showed low kappa number (16~22) and reject level (0.5~1.5%) with the best results for screened yield (47.41%) being achieved in soda pulping. With regard to strength and optical properties of the paper hand-sheets, soda-AQ pulping showed the highest value in burst index (2.36 KPa m2/g), tear index (8.47 + 1.13 mNm2/g), and brightness (19.81%), whereas kraft pulping gave the best result in tensile index (28.39 Nm/g). The comparatively low values of yield and strength properties in kraft pulping might be due to overcooking in this experiment.
