Abstract

Natural clay mask is a safe and effective alternative for skin care. This study aims to develop a clay mask based on Spirulina, enriched with sali-cylic acid, Centella asiatica, and clay, for natural skin care innovation. Three formulations were tested with different composition variations: (1) salicylic acid 0.50 g, Centella asiatica 5 mL, clay 10 mL; (2) salicylic acid 0.20 g, Centella asiatica 2.5 mL, clay 20 mL; and (3) salicylic acid 0.20 g, Centella asiatica 2.5 mL, clay 10 mL. The results showed that all formulations were physically stable with a pH suitable for the skin. Hedonic tests were conducted on 20 student respondents to evaluate preferences for the formulations. Respondents gave assessments based on as-pects of texture, aroma, color, and comfort of use. Formulation C1 is effective for acne-prone skin, C2 excels in spreadability for oily skin, and C3 provides a balance between cleansing and moisturizing. The combination of nutrient-rich Spirulina sp., clay, salicylic acid, and Centella asiatica produces a product that not only cleanses deeply, but also provides nutrition and prevents hydration to the skin. This product is safe, environmen-tally friendly, and has great potential to be developed in the cosmetic industry as a natural skin care.

The study uses an experimental approach with a design that only includes a post-test for comparison. Two classes were involved: class VIII-5 as the control group and class VIII-7 as the experimental group, making a total of 60 students. The method used to select the students was purposive sampling. The data was analyzed with SPSS version 26, using an Independent Samples t-test and also a quantitative descriptive analysis through percentages. The findings showed that students in the experimental group had better learning results than those in the control group. Most students from both groups gave positive comments about using Quizizz, which was considered “good. ” The t-test results also showed a big difference between the two groups, meaning that using Quizizz had a significant effect. So, it is hoped that teachers can use interactive tools like Quizizz in their lessons to help students learn better and stay more engaged. The study suggests that using digital tools like Quizizz can be a good way to evaluate learning, and teachers should consider using this technology to improve learning results, engagement, and interest in learning.

Abstract

QuizWhizzer is a digital game-based evaluation medium that offers interactive and engaging learning experiences. This study aims to develop QuizWhizzer as an evaluation tool for Islamic Religious Education (PAI) at SMP NU Palangka Raya. The research employed a Research and Development (R&D) method using the ADDIE model and a descriptive qualitative approach. The study was conducted from April 10 to June 10, 2025, involving Grade VIII-2 students. The instruments used included media expert validation questionnaires, evaluation questions, and teacher and student response questionnaires. The validation results indicated that the media is highly feasible for use, with scores of 98% from media experts, 97.5% from item experts after revisions, and response instrument validation scores of ≥81%. Teacher and student responses were also positive, at 91.67% and 70% respectively. The test items demonstrated high validity, a reliability coefficient of 0.86, varied difficulty levels, good discrimination power, and effective distractors. This study concludes that QuizWhizzer is suitable for use as an interactive digital evaluation medium, particularly for the topics of buying and selling, usury (riba), and debt. The novelty of this research lies in the use of a gamification platform for PAI learning evaluation at the junior high school level, which remains uncommon, especially through the use of the QuizWhizzer digital game board that enables interactive and game-based assessment.
