Abstract

Jelly candy made from watermelon rind and sappan wood is a candy with a soft texture that is processed with the addition of gelatin and low-calorie sugar. Based on the literature search that has been carried out. There has been no research regarding the antioxidant activity of jelly candy from watermelon rind and sappan wood. Him this research aims to determine the effect of varying concentrations of watermelon rind and wood extracts sappan in making formulations as jelly candy, the potential of jelly candy as an antioxidant, and to know the SNI 3574.2-2008 standard which includes water content, ash content, reducing sugar content and the condition aroma and taste of jelly candy. The results of the chemical properties test show that the water content in F3 meets SNI namely 19.891995%, and the ash content shows results that meet SNI, namely at F1 0.028%, F2 0.02905% and F3 0.02985%. Meanwhile, the reduced sugar content also shows results that meet SNI, namely F1 0.00219%, F2 0.00144% and F3 0.00048%. The organoleptic test results on the color indicator are 6.72 (somewhat like), the indicator of the aroma is 6.43 (somewhat like) and the taste indicator is 6.54 (somewhat like) and has met SNI with the condition normal. The results of the antioxidant activity test are in the medium category with an inhibition value of 36%.

Abstract

The increase in population has influenced the rising demand for water, and one way to meet this demand is by utilizing river water. Deli River is one of the rivers that flows through the city of Medan. The development of industries and settlements along the Deli River has affected its water quality due to heavy metal waste, specifically Fe, Pb, and Cu. This is evident from the deterioration of water quality characterized by changes in color and odor. One solution to address this issue is by using rice husk activated carbon as an adsorbent and aloe vera as a biocoagulant. Rice husk contains cellulose which can be converted into carbon and has a carbon content of 48.9%, while aloe vera contains mucilage which is an active coagulant used for water clarification. The principle used in this product is coagulation, which involves mixing chemicals, such as coagulants, with Deli River water followed by the adsorption process, where metal particles accumulate on the surface of the adsorbent. The results obtained showed a decrease in the parameters of Fe, Pb, and Cu metal content successively by 0.0092 mg/liter; 0.0081 mg/liter, and 0.0072 mg/liter. Thus, the filtered water meets the clean water quality standards set by Government Regulation No. 82 of 2001. Based on the existing problems and potentials, this product becomes a smart solution to assist the community, especially those in riverside areas, in water treatment and also addresses the challenges in preparing human resources that are actualized in facing the era 5.0 revolution.

Abstract

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia due to abnormalities in insulin secretion, insulin action or both and is included in the group of non-communicable diseases. In patients with type 2 diabetes mellitus, progressive hyperglycemia occurs resulting in insulin deficiency, where insulin deficiency can damage lipoprotein lipase activity and result in lower HDL levels and higher triglyceride levels. High triglyceride levels in type 2 diabetes mellitus patients result in increased macrophage infiltration into adipose tissue which causes an increase in the number of leukocytes. The aim of this research is to determine the relationship between the number of leukocytes and triglyceride levels in people with type 2 diabetes mellitus. This type of research is a quantitative descriptive laboratory observational approach. The number of samples in this research was 35 samples obtained through techniquespurposive sampling. Based on the results of the Pearson correlation static test analysis to determine the relationship between the number of leukocytes and triglyceride levels in type 2 diabetes mellitus sufferers, the sig value was 0.035, while for thePersonal Correlation namely 0.358 so it was concluded that there was a relationship indicating that there was sufficient correlation between the number of leukocytes and triglyceride levels

Abstract

Body health is an important thing, so many choices of methods for maintaining body fitness are offered. One way is to consume herbal plants that contain antioxidant compounds. Antioxidant compounds can neutralize and prevent damage caused by free radicals in the body. The plant that contains high antioxidant compounds is secang (Caesalpinia sappan L.). In previous research, a test of the antioxidant activity of this plant with an IC50 value of 11.37 ppm was reported, but a test to determine the total flavonoid content of the compound had never been carried out. So, this research is interesting to carry out with the aim of finding out the total flavonoid levels in a serving size of 0.05 grams of secang powder. The method for determining total flavonoid content used is the calorimetry method with AlCl3 reagent as a complex compound forming and quantitative analysis using an Ultraviolet Visible (UV-Vis) spectrophotometer. The flavonoid content value obtained was 0.2370% b/b for a serving size of 0.05 grams of sample. These results indicate that the secang sample contains flavonoid compounds which can be useful for increasing the body's immunity.
