Abstract

Wounds are tissue damage that is generally caused by physical contact. Wound healing is a complex mechanism involving biochemical and biocellular processes. Various therapies can be done to speed up the wound healing process, one of which is treatment using natural ingredients. One of the plants that have the potential to heal wounds is Oncidium Aliceara alice. The purpose of this study was to determine the phytochemical content of Oncidium Aliceara alice and its activity in wound healing when it is formulated in a gel form. This research is experimental research with extraction stages, phytochemical assay, gel formulations, quality test, and wound healing activity tests in animals. The gel formulation was made with various concentrations of Oncidium Aliceara alice extract 2.5%, 5% and 10%. Male Sprague Dawley rats were given an incision wound on the dorsum of the longitudinal axis along 3 cm. Wound care by administering topical Bioplacenton as a positive control, base gel as a negative control, and gel extract concentration variants according to each treatment group. Based on the research, the results of qualitative phytochemical tests showed that the 70% ethanol extract of Oncidium Aliceara alice contains flavonoids (catechins), tannins, steroids, and saponins. The best results were seen on the 7th day of observation for the 10% gel extract treatment group with more perfect signs of wound closure than the bioplacenton treatment.

Abstract

A cookie is a biscuit made from wheat flour as its main ingredient. Cookies have a crunchy and less dense texture. Wheat flour can be substituted with peanut tempeh flour and Cilembu cultivar sweet potato flour to increase the nutritional value. This study aims to determine the effect of substituting peanut tempeh flour and Cilembu cultivar sweet potato flour on the nutritional quality of the cookie. Four treatments were employed in this study. The ratio of wheat flour, peanut tempeh flour, and Cilembu cultivar sweet potato flour is the basis of the treatment. The treatments are K (100:0:0), A (60:35:5), B (60:25:15), and C (60:15:25). The results of this study prove that the substitution increases the nutritional quality. The cookie with treatment A has the best nutritional quality. It has water content 3.61% - 4.22%, ash content 0.93% - 1.43%, protein content of 8.15% - 14.11%, fat content of 21.17% - 32.70 %, carbohydrate content 48.33 % - 66.13 %, insoluble fiber content 1.23 %-2.73 %, soluble fiber content 4.90-8.44 %, white-orange color, texture 20.76-43.89 N, total plate count 1 x 101 CFU/g - 3 x 102 CFU/g, and the negative content of yeasts and molds. The cookies with treatment A  meet the requirements of  Indonesian National Standard (INS) 2973:2018 and INS 01-2973-2011. Cookies with treatment A is the best product based on chemical, physical, microbiological, and organoleptic values.
