Abstract

Characterization of physical and chemical properties of aroma compounds from liquid smoke is a challenge because there is no satisfactory method of separation due to compound contributors generally present in a matrix at very low concentrations. This study aimed to separate and identify the components of "strong and pungent" liquid smoke aromatic compounds by adsorption using activated carbon method. The observed variables analyzed using GC-MS including yield, phenol, carbonyl, titration acidity and chemical compound profiles. The chemical components of liquid smoke found on the analysis by GC-MS were further analyzed using a molecular mechanics software to determine the polarizability, hydrophobicity and dwipol moment of each compound     in the liquid smoke fraction adsorption results. The analysis of variance (ANOVA) with SPSS software version 16, followed by Duncan Multiple Range Test at the level of 1% was employed especially for the yield of liquid smoke adsorption. The physico-chemical characteristics of  25 fractions of liquid smoke resulted from adsorption on activated carbon at pH 2-6 comprising of 0.53 to 3.89% phenolic; 1.09 to 2.59% carbonyl; 7.17 to 10.75% acidicity; and pH range from     2.39 to 2.91 with the color spectrum in the range of 308-415 nm. The results of the analysis using the molecular mechanics methods showed that the higher the value of polarizability and dipole moment of a compound, the more polar the compound. It is concluded that the removal of the "strong and pungent" aroma compounds on coconut shell liquid smoke in order to produce a mild scent (soft) can be performed by activated carbon adsorption method despite the results were not optimal yet. A polar adsorbent such as zeolite is requiredin the adsorption method for the removal of "strong and pungent” aroma compounds on liquid smoke

Abstract

The ability of a company to generate profit can be measured simply by looking at the successful and the ability of the company to productively utilize capital structure. This observation had several objectives i.e. to identify (1) the use of capital structure at Irma Jaya Rattan Furniture in Palu, (2) the development of economic rentability at Irma Jaya Rattan Furniture in Palu and (3) the influence of capital structure to economic rentability at Irma Jaya Rattan Furniture in Palu. Respondents were purposively taken in volving the employer and six employees of Irma Jaya Rattan Furniture. The relationship between capital structure and rentability was analyzed using a simple linear regression analysis, correlation coefficient analysis, coefficient determination analysis and hypothesis t test.During the last ten years, the use of capital structure at Irma Jaya Rattan Furniture has increased by three times of loan period. The company preferred to finance its business using its own funds rather than loans from other sources. The development of economic rentability at this company has increased its capital structure. The correlation coefficient (r) found was 0.71 indicating a positively strong relationship. The coefficient determination was 50.05% reflecting that the capital structure had a moderately well influence on the rentability rate while 49.5% was affected by external factors not included in the observation. The result of thet test showed thatt-calc was 2.858 which is greater than t-table(1.680). Thus, H0 is rejected but H1 is accepted suggesting that there is a significant correlation between the capital structure andthe economic rentability at Irma Jaya Rattan Furniture in Palu City.   Key Words : Capital structure, economic rentability, and rattan furniture.

Abstract

The purpose of this study was to analyze the effect of inputs on wetland rice production and to determine their efficiency on wetland rice production in Toribulu Village of Toribulu Sub District, Parigi Moutong District. This study was conducted during March to May 2014. The number of respondents was 33 farmers out of 129 wetland rice farmer population selected using a simple random sampling technique. Data was analyzed using the cobb-douglas function and efficiency analysis. The input factors i.e land area (X1), seeds (X2), NPK fertilizer (X3), labor (X4), and pesticides (X5) both simultane ouslyand partially had significant effecton the rice production (Y). The coefficient of determination (R2) was 0.983 indicating that 98.3% of the variation in the variable factors of the rice production can be explained by all variables observed (Xi), while 1.7% is caused byother factors not included in the model. The efficiency scores of land area (X1), NPK fertilizer (X3), labor (X4), and pesticides (X5) were greater than 1 while seed (X2) was less than 1 suggesting that the former inputs used in the wetland rice production are not yet efficient but the latter is efficient in terms of price.
