Abstract

Student work readiness in facing the world of digital entrepreneurship is still an obstacle that requires a more effective learning approach. This study aims to examine the effectiveness of project-based learning model on students' work readiness in digital era entrepreneurship. By using pre-test and post-test design, 40 students were prepared to be tested at the beginning and at the end who were taught using a project-based learning model. Students participated in the learning process for one semester with real-world projects relevant to the digital fashion industry. The t-test results indicate a significant difference between pretest and posttest scores (t-calculated = 38.561 > t-table = 1.990; sig. < 0.05), indicating a significant improvement in digital work readiness. This improvement includes technical skills, creativity, digital literacy, collaboration, and business management skills based on technology. Additionally, project-based learning was proven to enhance students' motivation and engagement in the learning process. These findings reinforce the effectiveness of PjBL as an approach responsive to the demands of Industry 4.0. This study concludes that the project-based learning model is effective in preparing competent graduates in digital entrepreneurship and can be adopted as an adaptive and applicable vocational learning strategy in the era of digital transformation.

Abstract

The industry produces synthetic dye waste that has the potential to damage the environment, so that more environmentally friendly natural dye alternatives are needed. One of the plants that has the potential to be used as a source of natural dyes is the sicerek leaf (Clausena excavata Burm. F), because sicerek leaves contain flavonoid compounds that can produce color. This study aims to analyze the color names and color fastness to washing on Roberto Cavali's fabrics whose writings use sicerek leaf extract at various dyeing temperatures. The method used is the experimental method. Identification of color names was carried out by involving 18 panelists as respondents and supported by the use of the Colorblind Assistant application to assist in color determination. Meanwhile, color fastness to washing was tested using a gray scale and a staining scale according to SNI ISO standards. Data analysis used is descriptive statistical analysis and simple linear regression tests. The results of the study show (1) Differences in dyeing temperatures produce different color names, RGB values ??and hexadecimal codes at various dyeing temperatures. (2) The dyeing temperature does not have a significant effect on color fastness based on gray scale testing as proven by a simple linear regression test with a Sig. value. 0.351 > 0.05 which indicates that there is no difference or is not significant. Meanwhile, testing using a coloring scale at temperatures of 30?C, 60?C and 90?C shows a value of 4-5 with a good category for various types of multifiber including wool, acrylic, polyester, nylon, cotton and acetate. (3) The dyeing temperature of 90?C is the most optimal temperature in producing color and color fastness.
