Abstract

A study of the use of natural zeolite active as ammonia absorbent in an aquarium as the cultivation of medium fresh fish has been conducted. The water sample was taken from the surface water of Toba Lake, Pangururan, Samosir Regency. Natural zeolite was refined until measured at 200 mesh and activated by physics. Determination of ammonia was performed using spectrophotometrically with the Nessler method at the maximum wavelength of 410 nm. The result of the analysis of this study obtained that decrease in water pH and ammonia content in the water after feeding the fish was caused by the absorption of active natural zeolite active to the tenth day which concentration of ammonia on the first and tenth day was 1.2723 mg/L and 2.4171 mg/L with the largest absorption percent on the day to ten was 38.04%.

Abstract

The cationic surfactant of N, N-(2-Lauric-Ethyl) Stearamidium Chloride had been successfully synthesized. It is long-chain alkyl surfactant derivative from ammonium salt with amide. Cationic surfactants that are synthesized from fatty acid derivatives are stearic acid and lauric acid. Stearic acid is used as stearamide-making material which is the product of methyl stearate amidation with diethanolamine use methoxide sodium catalyst. Lauric acid was used as esterification material with stearamide thus obtaining N, N-(2-Lauric-Ethyl) Stearamide of alcanolamide ester. Alcanolamide ester continued by salting reaction use HCl gas until obtained cationic surfactant of N, N-(2-Lauric-Ethyl) Stearimidium Chloride. Each compound analyzed function groups by FT-IR spectrophotometric with the analyzed change of melting points, and a part compound analyzed surface tension characteristic with measuring Critical Micelle Concentration (CMC) with use Du Nouy ring method. The analysis product obtained shows that methyl stearate by yield in the amount of 91.66% shows that melting point of 40.5°C, stearamide with yield in the amount of 87.6% show that melting point as 185°C by CMC value 0.133 mol/ L in 40.7 dyne/cm surface tension. Alcanolamide ester with a yield in the amount of 84.7% has a melting point of 55°C by a CMC value of 0.067 mol/L in 36.1 dyne/cm surface tension, and cationic surfactant has a melting point of 45°C by CMC value 0.055 mol/L in 31,1 dyne/cm surface tension. stearamide with a yield in the amount of 87.6% show that melting point of 185°C by a CMC value of 0.133 mol/L in 40.7 dyne/cm surface tension. Alcanolamide ester with a yield in the amount of 84.7% has a melting point of 55°C by a CMC value of 0.067 mol/L in 36.1 dyne/cm surface tension, and cationic surfactant has melting point as 45°C by CMC value 0.055 mol/L in 31,1 dyne/cm surface tension. stearamide with a yield in the amount of 87.6% show that melting point of 185°C by a CMC value of 0.133 mol/L in 40.7 dyne/cm surface tension. Alcanolamide ester with a yield in the amount of 84.7% has a melting point of 55°C by a CMC value of 0.067 mol/L in 36.1 dyne/cm surface tension, and cationic surfactant has a melting point of 45°C by CMC value 0.055 mol/L in 31,1 dyne/cm surface tension.

Abstract

The determination of copper and zinc in soil based on the position and depth at the application land of palm oil in the Rambutan garden. Part of control land, between rorak and plant, and rorak at a depth of 0-20 cm, 20-40 cm and 40-60 cm. Each 3 g soil sample was destructed with 10 mL of HNO3 concentrated at 180ºC for 20 minutes. Cu and Zn's content was determined using Atomic Absorption Spectroscopy (AAS) at wavelength 324.7 nm and  213.9 nm, respectively. The analysis shows that Cu and Zn metal increase rorak at 84.0% and 57.7%, and soil between rorak and plant at 76.9% and 42.4%.

Abstract

The comparison of Lead in goat liver in an industrial and non-industrial area. The goat liver was drily digested, and then the ash of the goat liver dissolved with HNO3(p). Qualitative test using Inductively Coupled Plasma – Optical Emission (ICP – OES) where the sample results obtained I (Industrial area) = 0.088 ppm, sample II (Industrial area) = 0.080 ppm, sample III (Industrial area) = 0.086 ppm and sample IV (Non-Industrial area) = 0.022 ppm and Quantitative test determination of Pb content using Atomic Absorption Spectrophotometry (AAS) at a wavelength for Pb 217.0 nm. The result of the determination showed that the content in Lead of sample A (Non-Industrial Area) = 0.4585 mg/Kg, sample B (Non-Industrial Area) = 0.4490 mg/Kg, sample C (Industrial area) = 0.8761 mg/Kg and sample D (Industrial area) = 0.8622 mg/Kg. However, Pb of metal content fulfilled SNI 7387:2009 that 1.0 mg/Kg.
