Abstract

Pineapple peel can be used as a natural ingredient in making mosquito-repellent lotion because it contains many secondary metabolite compounds, including saponins, tannins, flavonoids, alkaloids, steroids, and essential oils. The research aims to obtain the right concentration of pineapple peel extract on the characteristics of the mosquito-repellent lotion produced. The method used was an experimental method with a Completely Randomized Design (CRD) consisting of five treatments (2%, 3%, 4%, 5%, and 6% pineapple peel extract) with three replications to obtain 15 experimental units. The selected treatment was LN2 (lotion with a 3% concentration of pineapple peel extract), providing homogeneous physical characteristics of the lotion preparation, a pH value of 7.93, a spread ability value of 5.50 cm, a viscosity value of 3829.51 cP, and mosquito protection power 80.16%. The descriptive organoleptic assessment showed that the color of the lotion was yellowish brown, slightly scented with citronella, and slightly sticky in texture, and the panelists liked the hedonic evaluation of color and texture. The panelists little appreciated the hedonic aroma.
