This study aims to analyze salicylic acid levels in anti-acne creams sold online and in pharmacies. Quantitative Testing uses UV -Vis Spectrophotometry and Alkalimetry. Quantitative testing using UV-Vis Spectrophotometry, there were 3 samples sold in pharmacies containing salicylic acid with sample levels A 1.568%, B 1.755%, C 0.895%, and samples sold online contained salicylic acid with sample levels D 0.151%. Alkalimetric quantitative testing, 3 samples sold in pharmacies contained salicylic acid with sample levels A 0.71%, B 0.36%, C 0.48%, and samples sold online contained salicylic acid with sample levels D 0, 42 %. Based on BPOM requirements, the permitted level of salicylic acid in cosmetics does not exceed 2%, so the anti-acne cream product meets BPOM requirements. The salicylic acid level was tested using Uv-Vis spectrophotometry and analyzed using Kruskal Wallis with a significance value of 0.00 (P0.05). It was said that the spectrophotometric method influenced determining the salicylic acid level from samples A – D. The salicylic acid level used alkalimetry. Homogeneity test with the Homogeneity of Variances test with a significance value of P (0.104 - 0.05) homogeneous data. Data were analyzed using ANOVA. The results of the One Way Anova test analysis show a significance value of 0.00 (P 0.05), so the salicylic acid levels of samples A – D carried out using alkalimetry show a significant difference between the 4 samples tested.

Abstract

Vitamin C merupakan nutrisi penting dengan sifat antioksidan, namun mudah terdegradasi oleh suhu, oksigen, dan cahaya. Penelitian ini bertujuan untuk menilai pengaruh suhu dan lama penyimpanan terhadap kadar vitamin C dalam manisan kedondong. Buah kedondong segar dimaniskan dan disimpan pada suhu kamar dan kulkas. Kadar vitamin C diukur pada hari ke-1, 3, 7, 14, 21, dan 28 menggunakan spektrofotometri UV-Vis. Hasil penelitian menunjukkan bahwa kadar vitamin C menurun signifikan seiring waktu, dengan degradasi yang lebih cepat pada suhu kamar. Setelah 28 hari, kadar vitamin C pada suhu kamar turun dari 0,0664% menjadi 0,0029%, sedangkan pada suhu kulkas, penurunan lebih lambat dengan sisa 0,0027%. Degradasi ini terutama disebabkan oleh oksidasi dan suhu. Penelitian ini menyimpulkan bahwa penyimpanan di kulkas lebih efektif daripada suhu kamar dalam mempertahankan kadar vitamin C pada manisan kedondong, yang penting untuk menjaga nilai gizinya. Kondisi penyimpanan yang tepat sangat penting untuk memperpanjang umur simpan dan kualitas produk pangan.
