Abstract

Cosmetics have become one of the most sought-after aspects for women today. One commonly used cosmetic product is lipstick, which is used to add color to the lips. This research aims to identify the presence of heavy metals in lipstick samples. The study encompasses two types of tests: qualitative and quantitative analysis of metal content in lipstick. The qualitative test aims to determine whether lipstick contains certain metals using simple reagents. Meanwhile, the quantitative test, involving the use of a UV-VIS spectrophotometer, is conducted to determine the concentration of metals that produced a positive result in the qualitative test. The qualitative test results indicate that the lipstick sample contains iron (Fe) as it exhibits a red color change. The quantitative test results reveal that the concentration of Fe in the lipstick is 6.0034 mg/kg, exceeding the recommended threshold set by the Department of Health (Depkes) Keywords: Trace Metal, Lip, UV-Vis Spectrophotometry

Abstract

This research used blood cockle shells (Anadara granosa) originating from consumption waste in the Batam City area. Cockle shell samples were taken and prepared for analysis of mineral content using the FTIR method, including CaCO3 and other minerals. The blood cockle shells were applied to ultisol soil in Batam City to improve its fertility. The shells were crushed into a fine powder, then mixed with ultisol soil with several treatments, including 0 grams (control), 10 grams, 20 grams, and 30 grams with a soil mass composition of 220 grams for each treatment. The mixture of soil and shell powder was stirred until homogeneous before being applied to mustard greens plants. Based on the research results, the addition of shell powder had an effect on the level of plant fertility. The experimental results carried out showed an effect on each treatment given. This is in line with statistical testing with analysis of variance, obtaining a sig. value of 0.037 < α = 5% (0.05), indicating a significant difference in treatment for each treatment.
