The content of flavonoid compounds in tin leaves has the potential to be an alternative source of natural antioxidants. The purpose of this study was to determine the formulation and physical quality test of tin leaf extract solid soap preparations. This research method is an experimental research and method of making soap using the cold process method. Making tin leaf extract solid soap by collecting the ingredients to be extracted using the maceration method with 70% ethanol solvent, carrying out formulations with extract concentrations of 0% 1% and 3% and evaluating the physical quality of solid soap preparations which include organoleptic tests, pH tests, homogeneity test and foam height test on tin leaf extract solid soap. Organoleptic test of solid soap F0 produces a light green color with black mystique perfume, F1 produces a dark green color with black mystique perfume, F2 produces a brownish green color with strawberry perfume. The pH value obtained, which is 9, meets the requirements, the pH range for solid soap for the skin is 9-11. The homogeneity test showed that the fig leaf extract herbal soap with a concentration of 1% and 3% showed no spots, therefore the fig leaf solid soap fulfilled the homogeneity requirements. The soap foam height test showed that soap produced foam (F0= 9.16Ccm, F1= 8cm, F2= 8.16cm)

Chewable tablets of metoclopramide HCl are made using diluent variations, they are mannitol, sucrose, lactose. Formula I mannitol, formula II sucrose, and formula III lactose. Chewable tablet preparations are made by the wet granulation method. Data collection was performed on physical characteristics including organoleptic, weight uniformity, uniformity of size, tablet hardness, tablet fragility, disintegration time, metoclopramide HCl levels. Physical quality test results were statistically analyzed to determine the effect of variations in the diluent on the characteristics of chewable tablets. The results of this research have an influence on the physical quality and uniformity of contents of various types of diluent variations between each formulation. In this research, fillers have an important role in the preparation of chewable metoclopramide tablets to determine the physical quality of the tablets and the uniformity of their contents. The variation of diluent that gives better results is mannitol. This is because formulas that use mannitol have uniformity in content that meets the requirements, faster disintegration time, and physical quality of tablets that still meet the requirements, when compared to the first and second formulations. The variation of diluent that gives better results is mannitol

Simultaneous Analysis of Dopamine and Ascorbic Acid Using Polymelamine/Gold Nanoparticle-Modified Carbon Paste Electrode
Modification of electrode using polymelamine (PM) and gold nanoparticles (AuNPs) has been successfully developed via electropolymerization and electrodeposition onto carbon paste electrode (CPE) using cyclic voltammetry (CV) technique. The modified electrode (AuNPs/PM/CPE) was applied as voltammetry sensors in a simultaneous of dopamine (DA) and ascorbic acid (AA). AuNPs/PM/CPE presented an effective surface area 5 times wider than CPE and demonstrated good electrocatalytic performance in the oxidation of DA and AA in 0.1 M phosphate buffer solution (pH 3) with a scan rate of 100 mV s−1. The differential pulse voltammetry (DPV) technique was chosen as the best method for separating potential peaks of DA and AA. The linear response for determining DA and AA using the DPV technique produced a concentration range of 0.1–13 and 0.4–12 µM with coefficient linearity of 0.9999 and 0.9997, the limit of detection of 0.1405 and 0.2187 µM, the accuracy of 89.62–109.16%, and 83.63–105.08%, and the precision of 0.017–0.701% and 0.066–0.626%, respectively. In addition, this electrode was applied in a real sample of infant urine with a concentration of 1 µM by spike method and found 98.86 and 98.28% as percent recovery of DA and AA, respectively
