Abstract

This study aimed to identify the effect of mechanical milling on the total phenolic content and antioxidant activity of mangosteen pericarp. Mangosteen pericarp was milled under different milling times (30, 90, 150, and 210 min). The particle morphology before and after milling was observed by scanning electron microscopy (SEM), and the average particle size was obtained from SEM images and analyzed statistically. The antioxidant activity was measured through the 2,2-diphenyl-1-picrylhydrazyl method. The total phenolic content for the non-milling sample was 14.52 × 104 µg GAE/g sample, and the highest total phenol content was 17.44 × 104 µg GAE/g sample for the sample milled for 210 min. The IC50 value decreased for samples with milling 150 and 210 min, which showed strong antioxidant activity, whereas the value of gallic acid equivalent increased. SEM observations showed the presence of agglomeration in the morphology of mangosteen pericarp samples. The average particle size of the mangosteen pericarp decreased as the milling time increased (up to 4499 nm for samples milled for 210 min). Therefore, mechanical milling had a significant effect on the phenolic content and antioxidant activity, which indicated an increase in the bioavailability of mangosteen pericarp.

Abstract

The COVID-19 pandemic has forced a global shift toward technical and inventive skills to improve job readiness and productivity. Human resources graduates from diploma levels 3 and 4 must respond with has competitively by adding value from soft skills. This can help them compete in domestic and international job markets. These skills are now required for professional acceptance. This study investigates the role of soft skills in learning and using information technology, the internet, and computers to boost individual and organizational efficiency. This study addresses all research questions and objectives using a combination of methods. We collected quantitative data on technology and innovation mastery ability gaps using online surveys. Comprehensive interviews with educational institutions, government agencies, industry representatives, and vocational diploma level 3 and 4 alumni were also conducted for the study. The data showed no statistically significant difference in alumni' technological proficiency between when they study and when they work. This shows that many former students have learned to use soft skills to boost their professional competitiveness and technical ability. ICT skills improve vocational human resources' employability, making them more competitive and competitive with undergraduate graduates. Keywords: Vocational, Soft Skill, Technology, Competencies, productivity, competitiveness

Abstract

The internet changes people's consumption patterns and shopping behavior. Online shopping activities can be done without leaving the house and can be done at any time. Online purchases are increasing during the pandemic due to Covid-19. Organic food business players can use internet marketing activities to attract more consumers, and one way that can be used is a marketing mix. This study analyzes the effect of the marketing mix on consumer trust and satisfaction in purchasing organic food online to increase repurchase intention. The population in this research is organic food consumers. The sample was taken using a purposive sampling method that targets consumers who live in the Jabodetabek area through an online questionnaire survey. Respondents who meet the criteria are 200 consumers. Structural Equation Modeling (SEM) was used in data processing and analysis. The results showed that the product and place had a significant effect on consumer satisfaction. Trust has a significant impact on satisfaction but had no significant effect on repurchase intention. Satisfaction had a significant effect on the repurchase intention of organic food. The suggestion for further research needs to analyze the types of organic rice, vegetables, and fruits purchased by consumers in more detail.
