Ready-to-eat sardines (RTE) are ready-to-eat foods designed to satisfy the needs of people who don’t have time to cook. In order to maintain the quality of RTE products and have a longer shelf life, efforts should be made to maintain the quality of RTE products, one of which is the use of cold storage methods and packaging. The purpose of this study was to estimate the shelf life of RTE sardines using the accelerated method combined with the Arrhenius method. This study employs a completely randomised Design with two factors: packaging type (vacuum and non-vacuum packaging) and storage temperature (cold storage and freezing temperature). The parameters tested in this research include TPC (total plate count), organoleptic properties, fat content, and protein content. The estimated shelf life of ready-to-eat sardines (RTE) in this study shows that RTE fish has a shelf life of up to 558.96 days if stored at a freezing temperature and vacuum packed, and 313.29 days if stored at a refrigerated temperature and vacuum packed. While ready-to-eat sardines (RTE) have a shelf life if stored using pouch packaging of 514.83 days at freezing and 2945.13 days at refrigerated temperatures with the Arrhenius equation obtained, namely ln k = (13.436 – 3034.6) (1/T).

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.
