IMPLEMENTASI MODEL PEMBELAJARAN PBL BERBANTUAN MEDIA AR UNTUK MENINGKATKAN KEMAMPUAN PROBLEM SOLVING DAN SELF EFFICACY DALAM PENGGUNAAN SUNSCREEN SISWA SMK

IMPLEMENTATION OF AR MEDIA-ASSISTED PBL LEARNING MODEL TO IMPROVE PROBLEM SOLVING AND SELF EFFICACY SKILLS IN THE USE OF SUNSCREEN BY VOCATIONAL SCHOOL STUDENTS

SMK Kecantikan fase E memiliki CP Perkembangan Penerapan Teknologi dan Isu Global. Pemanasan global relevan dengan penggunaan sunscreen seperti inovasi hybrid, tinted, dan eco-friendly. Wawancara guru SMK 8 Surabaya menegaskan pentingnya penguatan edukasi teknologi sunscreen agar siswa memahami tren, inovasi.

Metode yang digunakan adalah penelitian kuasi. Penelitian lebih ditekankan pada implementasi model pembelajaran PBL Berbantuan Media AR terhadap kemampuan Problem Solving dan Self Efficacy pada penggunaan Suncscreen siswa SMK. Data dikumpulkan dengan menggunakan instrumen tes dan kuesioner. Sebelum pengambilan data, dilakukan uji validasi, realibilitas, dan analisis butir soal. Kedua instrumen ini digunakan untuk saling melengkapi dan memperkuat data penelitian sehingga didapat data yang valid.

Berdasarkan hasil ANOVA menunjukkan bahwa Nilai F = 24,501 dengan dukungan nilai signifikansi (p value) sebesar 0,000 (p < 0,05) yang artinya terdapat perbedaan yang signifikan antara rata-rata kemampuan Problem Solving pada keempat kelompok. Kemudian pada uji lanjutan post hoc Games-Howell, terlihat bahwa model pembelajaran PBL berbantuan AR memberikan peningkatan signifikan (Mean Difference = 13,6) terhadap kemampuan Problem Solving antara kelompok Eksperimen-Pre dan Eksperimen-Post.

Hasil uji Paired Sample T-Test menunjukkan perbedaan yang sangat signifikan antara skor self-efficacy sebelum dan sesudah perlakuan. Nilai perbedaan rata-rata adalah -19.271 dengan nilai t = -12.716 yang didukung nilai signifikansi (p) sebesar 0.000 (p < 0.05).

Phase E of the Beauty Vocational School has a CP on the Development of Technology Application and Global Issues. Global warming is relevant to sunscreen use, including hybrid, tinted, and eco-friendly innovations. Interviews with teachers at SMK 8 Surabaya emphasized the importance of strengthening sunscreen technology education so students understand trends and innovations.

The method used was quasi-research. The research focused more on the implementation of the AR-assisted PBL learning model on students' abilities.Problem  Solving And Self Efficacy on useSuncscreen Vocational high school students. Data were collected using test instruments and questionnaires. Prior to data collection, validation and reliability tests and item analysis were conducted. These two instruments complemented and strengthened the research data to obtain valid data.

Based on the results of ANOVA, it shows that the F value = 24.501 with the support of a significance value (p value) of 0.000 (p <0.05) which means there is a significant difference between the average Problem Solving abilities in the four groups. Then in the follow-up post hoc Games-Howell test, it was seen that the PBL learning model assistedWITHprovides a significant increase (Mean Difference = 13.6) in the abilityProblem Solving between the Pre-Experiment and Post-Experiment groups.

The results of the Paired Sample T-Test showed a highly significant difference between self-efficacy scores before and after treatment. The average difference was -19.271 with a t-value of -12.716, supported by a significance value (p) of 0.000 (p < 0.05).
