Abstract

Research on antioxidant activity and vitamin C levels of dragon fruit and Hylocereus costaricensis dragon fruit syrup from Kulon Progo has been conducted. The purpose of this study was to study the antioxidant activity and levels of vitamin C in dragon fruit meat and dragon fruit syrup from Kulon Progo. The sampling method is done by purposive sampling method. The method of measuring antioxidant activity using DPPH (1,1-Diphenyl-2-picryl Hidrazil) immersion method was measured with a wavelength of 517 nm. The method of determining the level of vitamin C is carried out by the method of titration of Iodimetry using a standard solution of iodine. The results showed that the average antioxidant activity of dragon fruit was 67.81%, whereas in dragon fruit syrup was 42.81%. While the level of vitamin C in dragon fruit is 12.65% while in dragon fruit syrup is 3.667%. Can reduce the levels of antioxidants and vitamin C levels of dragon fruit higher than dragon fruit syrup.

Abstract

The background of this research was to examine the performance of homemade urine control materials on urine chloride examination. This study was aimed to test the performance of homemade control materials from addition and spike placebo simulation on urine chloride examination using the Fantus method. This research applied an experimental research method. The stages of the study started with standardization of AgNO3 solution, preparation of urine control materials from addition and spike placebo simulation, as well as calculation of accuracy (%R), bias (%d) and coefficient of variation (%CV). The results showed that the normal and pathological levels of accuracy in the urine control materials from addition were 109.55% and 104.30%, while the accuracy values (%R) ​​for urine control materials from spike placebo simulation, for the normal and pathological levels, were high, 110.07% and 104.54%. The bias values (%d) obtained in the urine control materials from addition with normal and high pathological levels were 9.55% and 4.30% bias, while the bias values (%d) in the urine control materials from spike placebo simulation with normal and high pathological levels were 10.07% and 4.54%. The coefficient variation (%CV) values ​​in urine control materials from addition at normal and pathological high levels were 3.75% and 3.07%, while the %CV values ​​in urine control materials from spike placebo simulation at normal and high pathological levels were 4.55% and 3.11%. This study concludes that based on the accuracy (%R) and bias (%d) parameters, the homemade control materials from addition and spike placebo simulation have relatively good performance for urine chloride examination using the Fantus method. Meanwhile, based on the parameter of coefficient of variation (%CVV), the homemade control materials from the addition and spike placebo simulation have slightly lower performance for examining urine chloride with the Fantus method.
