The use of food additives (BTP) in the food production process needs to be jointly monitored, both by producers and by consumers. The impact of its use can be either positive or negative for the community. This community service activity uses the educational socialization method by conducting counseling and demonstrations on how to make a dragon fruit peel formalin spray kit as a simple way to identify formalin in food. The purpose of this community service is to find out whether waste from dragon fruit peel can be used as a test tool for the formalin content of food preparations in food preparations. The results of Community Service obtained a good knowledge category with the achievement of participants' knowledge levels before counseling and demonstration in the less (26.7%) sufficient (40%) and good (33.3) categories, after the extension the results of the category increased significantly, namely less 0 ( 0%), sufficient (13.4%), and good (86.6%).

Antioxidants are compounds that can inhibit oxidation reactions by binding to free radicals and highly reactive molecules. Bintangur contains saponins, tannins, flavonoids and alkaloids. In the presence of flavonoids, the purpose of this study is to understand the antioxidant activity of ethanol extracts against DPPH free radicals, and the IC50 parameter has the highest antioxidant activity. Use ethanol to macerate Bintangur leaf powder. Analyze the content of secondary metabolites in ethanol extracts. Use a spectrophotometer to test the antioxidant activity of the obtained extract against DPPH free radicals at a wavelength of 517 nm, and determine the IC50 value. Routine was used as a positive control in this study. The results of three repeated studies showed that the IC50 values ​​of the ethanol extract were 65.49 ppm, 65.76 ppm, and 65.76 ppm, respectively. Average IC50 value is 55.67 ppm.

Daun merupakan bagian tanaman yang berfungsi untuk mempertahankan kehidupan, mengingat fungsinya tersebut maka alat ini sering disebut dengan alat vegetatif, pada batasnya terdapat daun berbentuk tunggal dan tersusun dalam bentuk spiral. Daun alpukat disebut daun tidak lengkap karena hanya terdiri dari tangkai dan helaian saja, tanpa upih atau pelepah daun.
