The independent variables used are work (X1), status (X2), boss (X3), colleagues (X4), and promotion (X5), while the dependent variable is employee satisfaction (Y). Here, the method used in this research is multiple linear regression. Based on statistical data analysis, the indicators in this study are valid and are reliable variables. In the classic assumption test, the regression of multicolinierity free model, there is no heteroskedastisitas for the data and it has normal distribution. The sequence of the most influential variables individually are as follows: status (X1) with a regression coefficient of 1.095, boss (X2) with a regression coefficient of 0.644, job (X3) with a regression coefficient of 0.084, and colleagues (X4) with a regression coefficient of 0.019, while the lowest influential variable is sale (X5) with a regression coefficient of - 0.066.

Abstract

The study of inhibition testing antibacterial extract Fresh Red Ginger Zingiber officinale var. Rubrum Against Staphylococcus aureus, and Escherichia coliguna to determine the source of antibacterial natural products, especially red ginger has been conducted. Anti-bacterial inhibition test using disc diffusion method with fresh red ginger rhizome material. The study was conducted using concentrations: 0%, 20%, 40%, 60%, 80%, and 100%. Concentration of 0% was used as a negative control. The data obtained will be tested statistically using ANOVA with sig. 0.05. The results showed that the extraction of fresh red ginger (Zingiber officinale var. Rubrum) at a concentration of 100% has the highest inhibitory region to S. aureus (15.83 mm)and E. coli (14:22 mm). It can be concluded that the extract of fresh red ginger Zingiber officinale var. Rubrum at a concentration of 100% has a moderate level of inhibition to S. aureus and weak level of inhibition to E. coli. Keywords: Escherichia coli, Fresh red ginger extract of Zingiber officinale var. Rubrum, Staphylococcus aureus.

Abstract

Falling film evaporator is a constructed equipment for concentrating dilute solution that are sensitive to heat flowing form a thin film. This research aims to study the evaporation of cane juice concentrated with air flow on falling film evaporator and knowing evaporation rate occured in falling film evaporator used. In the process, cane juice from plant pumped to the falling film evaporator that used in this experiment. This research used concentrated cane juice and air flow rate for variables of this experiment. Cane juice flow from top of evaporator through distributor to form thin film and air flow from the bottom of evaporator. After that, temperatur of pipe wall, inlet and outlet temperature of cane juice and air were measured. This experiment concluded that the highest concentration of outlet solution is 59 brix for liquid flow rate 154 l/h and air flow rate 10 m3/h, and the other hand inlet solution concentration 51 brix. Optimum evaporation rate is 35 kg/m2.h for 51 brix and air flow rate 10 m3/h. Keywords: Concentrated cane juice, Evaporator, Evaporation rate, Falling film.
