The aim of the study was to measure nutritional status of under five children in both groups. There were 94 under five children in group of ore-PF and 94 under five children in group of PF-l. It was found that the nutritional status of both groups was significantly different. Significant difference was also noted when they were classified according to father's occupational status and father's education level. However when they were grouped according to maternal education, number of children in the family, and occurrence of disease in the previous month no significant difference was detected.

Abstract

Pineapple or which has the Latin name Ananas Comosus L. MERR has two main ingredients, namely vitamin C and manganese. Vitamin C is very important for the growth and development of the immune system and can help the absorption of iron from food, meanwhile manganese is a natural mineral that has antioxidant properties or can ward off evil compounds in the body and help increase the body's immunity to avoid the Covid-19 disease outbreak.. Therefore, researchers are interested in researching pineapple juice, because what people consume every day is pineapple juice. The aim of this research was to determine the levels of vitamin C in pineapple juice (Ananas comosus L. MERR) and whether the vitamin C content in pineapple juice (Ananas comosus L. MERR) can meet daily nutritional adequacy rates. This research method uses quantitative methods. Where is the relationship between the independent variable and the dependent variable. The independent variable is pineapple filtrate and the dependent variable is vitamin C content. The parameters of this research are vitamin C levels using the UV Spectrophotometry method. The conclusion of this study shows that the results of the examination of pineapple juice levels are 54.6816 21.6678 mcg/g, and the vitamin C content in pineapple juice can meet the daily nutritional adequacy figure, namely 33 mg to 76 mg.

Abstract

Some food industries still use synthetic dyes. Synthetic dyes, if consumed, can harm your health. Turmeric can be used as a natural food coloring. This natural coloring is applied to sweet jelly. This natural coloring agent must be used in fresh juice. To extend the use time of the natural dyes turmeric-bay leaves, ginger-bay leaves, this research was carried out in a variety of storage conditions without using preservatives. The aim of the research was to determine the results of the content of secondary metabolite compounds in turmeric-laurel extract, curcuma-laurel extract, turmeric extract and curcuma extract, in making solid preparations using preservatives, namely citric acid, maltodextin and sucrose. This research uses experimental methods with Sari method is done on a mixture of turmeric-bay leaves and ginger-bay leaves using a water solvent using the distillation method. Determination of variations in storage conditions was carried out for 7 days and the effect of storage temperature. Color stability and intensity measurements were carried out using visible spectrophotometry and characterization methods. The results of this research were obtained. The absorbance intensity test on turmeric-bay leaves was carried out at a wavelength of 425.14 nm with a result of 0.442 (day 1), ginger-bay leaves had an absorbance of 0.490 ( day 1). In the color stability test, there was a change in color from day 3 at drying cupboard temperature, at refrigerator temperature and at room temperature, the color remained stable.
