Abstract

This study aim to compare learning outcomes in Class XI SMAN 1 Pantai Cermin using the Quizizz Aplication-assisted Discovery Learning learning model versus the Conventional learning model. A quasi-experimental design, purposive sampling technique, instrument testing, gain score, validity, reliability, different test questions, and level of difficulty were all used in the study. Data collection and documentation, as well as learning outcomes tests This study's population was class XI IPS SMA N 1 Pantai Cermin, with samples XI IPS 3 for the experimental class and XI IPS 2 for the control class. The paired sample t-test and independent sample t-test analysis methods were used. The study found that there are differences in student learning outcomes when using the Quizizz Aplication assisted Discovery Learning learning model versus traditional methods.

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.

Abstract

This study examined the effectiveness of video tutorials in enhancing students’ cognitive understanding and psychomotor skills in Flat Pattern Design learning. A quasi-experimental pretest–posttest design was employed involving 30 fashion design students selected through purposive sampling. The instructional intervention utilized video tutorials that demonstrated each stage of the flat pattern design process, enabling students to review learning materials repeatedly and practice independently. Data were collected through cognitive achievement tests and psychomotor performance assessments and analyzed using descriptive and inferential statistics. The findings revealed statistically significant improvements in students’ learning outcomes following the intervention (p < 0.05). Cognitive achievement scores increased from pretest to posttest, accompanied by substantial gains in psychomotor performance. Classroom observations also indicated high levels of participation and engagement throughout the learning activities. These results suggest that video tutorials provide effective support for procedural learning by facilitating visual demonstration, self-paced practice, and skill mastery. The study contributes to the growing body of research on digital learning in vocational education by demonstrating the potential of video-based instruction to strengthen both conceptual understanding and practical competencies in fashion design courses

Abstract

ABSTRACT This study was motivated by the difficulties experienced by grade XI students majoring in Fashion Design and Production at SMKN 1 Tebo in understanding how to create patterns for women’s pants in the Vocational Competency course, particularly due to the limited availability of learning materials that would allow students to learn independently. This study aims to develop valid and practical instructional media in the form of a video tutorial on creating women’s pants patterns using the Soekarno system. The research method used is Research and Development (R&D) with the 4-D development model, which includes the Define, Design, Develop, and Disseminate stages; however, this study is limited to the Develop stage. Data collection techniques included observation, interviews, and assessment sheets. Validity testing was conducted by five validators—comprising three subject matter experts and two media experts—while practicality testing was carried out by one subject teacher and grade XI students through small-group testing involving 9 students and large-group testing involving 28 students. The results showed a content validity rate of 96.44% and a media validity rate of 95%, with an average validity of 95.72% in the highly valid category. The results of the practicality test conducted by teachers showed that 96.44% of the videos were rated as highly practical, while the student test yielded 87.65% in the small group and 91.07% in the large group, with an average of 91.72% rated as highly practical. Thus, the tutorial videos developed were deemed suitable for use as a learning medium. ABSTRAK Penelitian ini dilatarbelakangi oleh kesulitan siswa kelas XI jurusan Desain dan Produksi Busana di SMKN 1 Tebo dalam memahami pembuatan pola celana wanita pada mata pelajaran Kompetensi Kejuruan, khususnya karena keterbatasan media pembelajaran yang memungkinkan siswa belajar secara mandiri. Penelitian ini bertujuan untuk mengembangkan media pembelajaran berupa video tutorial pembuatan pola celana wanita sistem Soekarno yang valid dan praktis. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan 4-D yang meliputi tahap Define, Design, Develop, dan Disseminate, namun penelitian ini dibatasi hanya sampai tahap Develop. Teknik pengumpulan data dilakukan melalui observasi, wawancara, dan lembar penilaian. Uji validitas dilakukan oleh lima validator yang terdiri dari 3 ahli materi dan 2 ahli media, sedangkan uji praktikalitas dilakukan oleh 1 orang guru mata pelajaran serta siswa kelas XI melalui uji kelompok kecil oleh 9 orang siswa dan kelompok besar oleh 28 orang siswa. Hasil penelitian menunjukkan tingkat validitas materi sebesar 96,44% dan validitas media sebesar 95%, dengan rata-rata validitas 95,72% kategori sangat valid. Hasil uji praktikalitas oleh guru mencapai 96,44% kategori sangat praktis, sedangkan uji siswa memperoleh 87,65% pada kelompok kecil dan 91,07% pada kelompok besar dengan rata-rata 91,72% kategori sangat praktis. Dengan demikian, video tutorial yang dikembangkan dinyatakan layak digunakan sebagai media pembelajaran.
