Oleh karena itu, dengan memanfaatkan bunga kiacret sebagai pewarna alami dapat meningkatkan nilai guna terhadap bunga kiacret. Penelitianl ini bertujuanl untuk mengetahuil perbedaan jumlah rendemen, kadarl total lantosianin, danl stabilitas zatl warna ekstrakl etanol 70%l dan l96% bunga kiacret terhadapl pengaruh pH (3–6), suhu (40°C–80°C), dan waktu penyimpanan selama 5 hari. Penelitianl ini menggunakanl metode eksperimen laboratorium melalui prosesl ekstraksi sampel denganl metode lmaserasi, uji kadar antosianin, dan uji stabilitas ekstrak. Hasill penelitian menunjukkanl bahwa ekstrakl etanol l70% bunga kiacret memperoleh nilail rendemen 42,02%, dan kadar antosianin 8,908 mg/L, sedangkan ekstrak etanol 96% bunga kiacret memperoleh rendemen 35,72%, dan kadar antosianin 10,949 mg/L. Ekstrak bunga kiacret stabil pada pH 3–4, suhul 40°C, danl penyimpanan selamal satu lhari. Hasill stabilitas terbaik diperoleh pada ekstraksi bunga kiacret dengan pelarut etanol 96% yang dapat dilihat pada absorbansi tiap perlakuan yang diperoleh lebih tinggi dibandingkan dengan pelarut etanol 70%.

Abstract

The use of skincare products among adolescents is increasing, yet it is often not accompanied by adequate knowledge regarding safety and proper usage. One important aspect that is frequently overlooked is the period after opening, which determines the safe duration of product use after the packaging is opened. This issue may lead to health risks such as irritation, infection, and reduced skin quality if products are used beyond the recommended period. This activity aimed to improve students’ understanding of the period after opening, its difference from the expiration date, and the importance of selecting safe and authorized products. The method included health education through counseling, distribution of fan-shaped leaflets, question-and-answer sessions, and interactive games, followed by pre-test and post-test assessments involving 38 students of SMP Negeri 10 Samarinda. The analysis showed an increase in the average knowledge score from 11.34 in the pre-test to 15.21 in the post-test, with a paired t-test result indicating a significance value of 0.000 (p < 0.05), demonstrating a significant difference before and after the education. The majority of students who initially had a moderate level of knowledge improved to a good category after the intervention. In conclusion, education on the period after opening and safe use of skincare products proved effective in enhancing students’ knowledge and critical awareness, thereby serving as a preventive effort to protect adolescent skin health.
