Abstract

Schiff base is a chemical compound that is formed from the reaction between aldehydes and primary amines by condensation and produces by-products in the form of water. Schiff base is the raw material that is added in making Fragrance. The purpose of this study was to determine the method of synthesis of Schiff base verdantiol with simple condensation. The research method was carried out with four stages: preparation, synthesis, testing and measurement of parameters, and calculations. Preparation includes weighing the raw material Schiff base verdantiol. Schiff base synthesis is carried out by stirring at a temperature of about 90°C ± 5° C (Arctender, 1969) with a modification time of 15 minutes, 30 minutes, 1 hour, 2 hours and 3 hours. Testing and measurement parameters include organoleptic, density and specific gravity tests in pycnometer and compound confirmation using Gas Chromatography Mass Spectrometry. The results showed that the optimum synthesis of Schiff base verdantiol compounds was carried out at a heating time of 2 hours. The results of odor, color, density and gravity specifications heating time 2 hours according to specifications with the standard. GCMS confirmation results at 2 hours percent similarity are above 94%.

Abstract

Increased human activities will cause various problems, one of which is water pollution in water sources because it receives a pollution load that exceeds its carrying capacity. In the context of environmental conservation, the government has set quality standards for liquid waste produced by various industries and other activities in a Decree of the State Minister for the Environment. COD (Chemical Oxygen Demand) is one of the most important parameters in wastewater quality standards. This study aims to validate the COD analysis method which refers to COD Thermoreactor System (LOVIBOND brand) at Pakuan University Service Laboratory, to ensure the validity of COD analysis results at Pakuan University Service Laboratory. Spectrodirect COD analysis method provides results that meet the requirements of accuracy, precision, LOD, and LOQ which is quite good. The results of the Coefficient of Variation give good results with a value of 1.8841% indicating the accuracy of the analysis method is good. The accuracy parameter also gives good results and meets the requirements with a% recovery value of 98.70351%. Overall, it can be stated that the spectrodirect analysis method tested is an accurate, precise, simple, and economical method for determining COD levels
