Abstract

Nata de batatas is a product of purple sweet potato peel. The presence of anthocyanin compounds in purple sweet potato skin makes this food very attractive to be processed into nata products that have functional value. The purpose of this research was to determine the yield of nata from purple sweet potato peel made with variations in the percentage of purple sweet potato peel extract and the percentage of coconut water and pellicle thickness, evaluate organoleptic properties including texture, color, aroma, taste, and determine anthocyanin levels. The results showed that the highest nata yield was 70.08%. The thickness of the largest 1.26 cm. The best anthocyanin analysis in nata was 0.47 mg. The organoleptic test showed that the color percentage of purple sweet potato peel extract and the percentage of coconut water were significantly different while the texture, aroma and taste were not significantly different. Keywords: nata de batatas, purple sweet potato skin, coconut water, anthocyanin

Abstract

The purpose of this study was to analyze the effect of temperature and drying time on the characteristics of the chemical componens of papaya jelly candy and evaluate the level of preference for papaya jelly candy that is dried at different temperatures and drying times. This study used a completely randomized design (CRD) method which consisted of four treatments and three repetitions with different temperatures and drying times, namely : treatment drying using room temperature for 48 hours; drying at 40°C for 36 hour; drying at 50°C for 24 hours; and drying at 60°C for 8 hours o’clock. The resut of this study indicate that differences in temperature and drying time produce papaya jelly candy with chemical characteristics, namely water content (10.49% - 23.73%), sucrose (13.78% - 16.25), and pH (6.17% – 5,35%). The papaya jelly candy with the most preffered color, aroma, taste, and texture by the panelists was dried at room temperature for 48 hours. Keywords: jelly candy; papaya; drying; sucrose.

Abstract

Uric acid is the last metabolite of purines, which is one of the components of nucleic acids found in the nucleus of human cells. Many factors can affect a person's uric acid levels, such as genetics, lifestyle and physical activity. Coffee is one of the world's most popular drinks. The purpose of this research is determine the descriptionof blood uric acid levels in adult men who have the habit of drinking coffee with Robusta and Arabica coffee. The type of research used is descriptive analytic using cross- sectional analytic method. The population in this study were patients with gout who had a habit of drinking coffee at RSU Mayjen H.A Thalib Kerinci. The sample in this study was taken as many as 40 people with uric acid patien. Based on the research results, giving of the t test 0.178> 0.05 showed that there was no difference in uric acid levels between the types of Robusta and Arabica coffee. Keywords: Uric acid; coffee.

Abstract

The research is aimed at: 1. Modified the teta '17, 2 model rack dryer. Testing instrument performance includes temperature, air humidity, water levels and the drying rate of water. The study is conducted using experimental methods for tooling and data analysis using descriptive methods that the data from observation is compiled in the form of a chart, then described in graph form, and described. Each rack of the top shelf and lower shelf each USES 500 nutmeg samples. Each experiment was performed 2 (two) times a test. The observed variables are temperature, humidity, water content and drying rate. The results of this study have modified the teta '17 model rack dryer by adding a chimney to no condensation on the surface of the instrument wall. Based on the average, the top temperature temperature is 53rd and the lower shelf average, at 55 plenum, and the average temperature in plenum is 54 plenum. The average air humidity in plenum is 70%. The average high levels of nutmeg water amount to 10.2% and bottom shelf 8.7%. The curing time it takes to dry the nutmeg to a water level of 8-10% is 11 hours. The rate of drying off the water level of deuteronomy 1 top shelf by 2.55%, bottom shelf 2.72% and 2.65% top shelf by 2.65%, bottom shelf by 2.75%.
