Abstract

: Penelitian ini bertujuan untuk menilai apakah penerapan model PjBL dengan media pembelajaran interaktif dapat meningkatkan keterampilan pemecahan masalah dan komunikasi mahasiswa. Penelitian ini menggunakan desain quasi eksperimen dengan pretest-posttest control group design. Sampel terdiri dari 60 mahasiswa yang dibagi menjadi kelas eksperimen (30 siswa) dan kelas kontrol (30 siswa). Instrumen yang digunakan meliputi tes keterampilan pemecahan masalah, tes komunikasi, dan lembar observasi. Hasil penelitian menunjukkan bahwa kelas eksperimen yang menggunakan media pembelajaran interaktif mengalami peningkatan keterampilan pemecahan masalah dengan nilai rata-rata normalisasi 0,67 (kategori tinggi), sedangkan kelas kontrol sebesar 0,49 (kategori sedang). Peningkatan keterampilan komunikasi tulisan pada kelas eksperimen memperoleh skor 0,66, sedangkan kelas kontrol 0,46 (kategori rata-rata). Pencapaian keterampilan komunikasi lisan pada kedua kelompok mencapai 87,68% (kategori tinggi). Uji beda rata-rata pada taraf kepercayaan 95% menunjukkan bahwa model PjBL dengan media interaktif lebih efektif dalam meningkatkan keterampilan pemecahan masalah dan komunikasi tulisan dibandingkan dengan model PjBL tanpa media interaktif.

Abstract

The 21st century learning paradigm emphasizes the development of Higher Order Thinking Skills (HOTS) to prepare learners with essential competencies such as critical thinking, problem-solving, decision-making, and creativity. This study developed HOTS-based learning materials for the Makeup Room Decoration course using the Problem-Based Learning (PBL) model with a Case Method (CM) and the Project-Based Learning (PjBL) model with a Team-Based Project (TBP) approach. The research employed Thiagarajan’s 4-D model, consisting of four stages: define, design, develop, and disseminate. The developed products included a Semester Learning Plan (RPS), an e-book with video tutorials, and a HOTS test instrument. The research trials were conducted in three stages-expert validation, limited trials, and field trials-involving experts, lecturers, and students. Data were collected using observation sheets, validation forms, assessment questionnaires, and tests. The results indicated that the developed learning materials met the criteria for validity, practicality, and effectiveness. The RPS was categorized as highly valid (Aiken’s V = 0.8375), the e-book as moderately valid (V = 0.723 by learning design experts and V = 0.823 by media experts), and the HOTS test instrument as highly valid (V = 0.937). The limited trials showed that the materials were very practical, while field trials demonstrated effectiveness with an average student achievement rate of 81.7%. These findings confirm that the developed learning materials are feasible and effective in enhancing students’ higher-order thinking skills in the Makeup Room Decoration course of the Beauty Education Program at the State University of Medan.

Abstract

Fantasy hair styling in vocational cosmetology is commonly treated as a tacit craft activity, leaving limited evidence that material and geometry choices lead to ergonomic and stable designs. This study aimed to develop and validate craft-based support frames for fantasy buns while making materials-science and basic biomechanics concepts explicit. Using a 4D Research and Development model (Define–Design–Develop–Disseminate), undergraduate cosmetology students produced three frame variants (foam, thin wire, and polymer mesh). Product quality was evaluated by three cosmetology/beauty-education experts using a 1–5 Likert rubric covering aesthetics (neatness, proportion, creativity, harmony) and ergonomics (comfort, lightweight, ease of application/removal, positional stability). Three models conducted short wear-and-movement trials (standing, walking, head turns). Quantitative scores were converted to percentages and categorized; expert comments were analyzed thematically. Aesthetic performance averaged 87% (Very Good: neatness 90%, proportion 85%, creativity 88%, harmony 85%). Ergonomic performance averaged 83% (Very Good: comfort 85%, lightweight 82%, ease 80% [Good], stability 85%), with frame weights ranging from ~500 to 2,000 g. These results indicate that craft-based frames can produce visually coherent and ergonomically acceptable fantasy buns while supporting concept-based reasoning; future work should strengthen durability and application techniques and extend trials to longer wear durations.
