Abstract

The use of Computer-Aided Design (CAD) software in fashion pattern making, particularly CAD Pattern Making, provides opportunities for students to develop their digital design skills. However, not all students are able to understand the pattern making process, such as camisole patterns using the CAD Pattern Making application. Most students experience difficulties in applying theory to practice and feel less confident due to limited references on the use of these tools and software. This study aims to develop video learning media as a medium in CAD Pattern Making courses to minimize the difficulties students face in understanding the concepts and practices of pattern making. This study uses a qualitative approach with 30 third-semester students from the Family Welfare Education Study Program as research subjects. Data collection techniques included interviews, observations, direct observation, and activity documentation. The learning videos developed covered several key elements, including: learning objectives, introduction to the features or tools used, steps for making patterns, and practical tips for making digital camisole patterns. The results of the study indicate that instructional videos can optimize the practical learning process. Students find it easier to understand the use of software features, such as point determination, measurement, line joining, and pattern simulation. These findings indicate that visual media are more effective than lectures or printed teaching materials in explaining the technical concepts of CAD Pattern Making.

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.
