This study is a quasi experimental, using a model reaction between 0.2 % BSA were heated to form protein denaturation by five groups: red ginger water extract group, red ginger ethanol extract group, big white ginger water extract group, and big white ginger ethanol extract group as the test group (200 ppm, 100 ppm, 10 ppm, and 1 ppm) and diclofenac sodium as the standard group (40 ppm, 20 ppm, 10 ppm, 5 ppm, 2.5 ppm, and 1.3 ppm). Potential inhibition of protein denaturation is known to determine the value of IC50. The results of this study indicate that the red ginger water extract has the IC50 value of 107.4513 ppm (r=0.967), the red ginger ethanol extract has the IC50 value of 193.4338 ppm (r=0.959), the big white ginger water extract has the IC50 va...

The growth of Indonesia’s leading local foodservice chain new outlet is only at the average of 3.48% while the international counterparts is at 8.24% over the past 5 years. This study has two bifocal objectives namely to examine the direct effect of specified predictors on goal realization and to examine the indirect effect or mediating effects of specified predictors on goal realization. Quantitative method is the main research design used with the local franchisees as the unit of analysis. From the 230 questionnaire distributed, 100 completed questionnaires were returned, representing 44 percent response rate. The questionnaire consists of 70 items measuring nine constructs which are goal realization; plan enactment; implementation intention, implementation desire; goal intention; goal desire; self-efficacy; attitude; and subjective norms. Partial Least Square throu...

Research paper thumbnail of Synthesis, Characterisation, and Density Functional Theory Study of Encapsulated Bioactive Components of Ginger

Ginger nanocapsules were characterised using Transmission Electron Microscope (TEM) and Particle Size Analyser (PSA). The results show that the nanoparticles have a generally globular shape with particle size under 200 nm. In addition, the simulation of gingerol and dextran, as a representative for maltodextrin, was also investigated using Density Functional Theory (DFT) calculation. From the DFT calculation, gingerol exhibited a physisorption interaction with dextran by forming hydrogen bonds. Furthermore, the density of state analysis shows that the gingerol-dextran system has a conductive-like behaviour that promotes the nanocapsules’ cell uptake.

Research paper thumbnail of Transformational Leadership and Job Satisfaction

Medium-scale companies have a different phenomenon in their leadership. In small-scale companies with a fairly simple problem complexity, the best approach to leadership is to use transactional leadership. Conversely, when the company is getting bigger, it should use transformational leadership. Thus, medium-scale companies need to test the right leadership model and we assume that leaders in medium-sized companies should start to focus on being transformational and start reducing transactional. To test the hypothesized model, this study used a survey questionnaire research design and a quantitative approach. Data collection by researchers was carried out by sending questionnaires to middle manager level employees (supervisors; managers) at 6 textile companies in Central Java Province via email. This shows that the data taken can be said to represent the condition of textile companies in Solo City, Central Java Indonesia. This study shows clearly that the transformational leadership style has a significant and positive effect on employee rewards. Furthermore, rewards have a positive and significant effect on employee job satisfaction.

Research paper thumbnail of Self-Efficacy as Mediator: The Impact of Entrepreneur Education on Entrepreneur Intention

This study aims to meet that purpose. From the response of 241 students in Jogjakarta, which was analyzed using structural equation modeling (SEM), it is concluded that self-efficacy mediates the relationship. This finding signifies the role of entrepreneurship education as it builds self-efficacy to become an entrepreneur, which in turn increases the intention to become one.

Data collection used in the study was carried out through questionnaires. The population in this study are all visitors who come to the Glagah Beach tourism object. Taking into the large number of populations that are not known with certainty, then in this study 100 samples were taken. The selected respondents were visitors to the Glagah Beach tourism object who also visited Congot Beach and Kiskendo Goa attractions, both after visiting Glagah Beach and before visiting Glagah Beach. Sampling is done through accidental sampling. Data analysis was performed through multiple regression analysis with the F test, t test, determination test. The results showed that the cost of travel to Glagah Beach tourism objects, the cost of travel to other attractions, and income per month have negative influence to the numb...
