Abstract

A researchon the utilization of shrimp shell waste are abundan tin the province of East Kalimantan as the source of chitosan and synthesis of the derivative chelating chitosan-ethylene diamine tetra acetate (EDTA) resin and the retention of characterization for Cu(II) ions has been carried out. Chitin were obtained from Windu Shrimp’s (Penaeus monodon) shell through three ways, are deproteination, demineralitation and depigmentation. The obtained chitin were deacetylated with sodium hydroxide at temperature 150-160˚C during 1 hour to obtained chitosan, with contain was 64.4%. Synthesis chitosan-EDTA resin can be done by coupling reacts between diazonium ion from diazotation chitosan with EDTA at temperature 1-3˚C during 1 hour, the product of 70% yield was obtained. The Chitosan-EDTA resin was synthesized has characterization by using FT-IR spectroscopic and scanning electron microscope, shows the spesific functional groups of the resin.

Abstract

Fish is a source of omega-3 which is good for our health. This study used one type of fish that contains high omega-3 (Rastrelliger kanagurta L.). This fish as s feed against the decrease in total blood cholesterol levels in mice (Mus musculus) are hypercholesterolemia. There are 5 treatments used in this study, i.e positive control, negative control, and mice which given the addition of bloated fish on standard feed with 3 different treatments L1 (2:1), L2 (2:2), L3 (1:2). Parameters measurement of total cholesterol level of mice is using CHOD-PAP method. The principle used in determining the total cholesterol level of mice blood cholesterol obtained is (+) 142 ; (-) 86 ; (L1) 108 ; (L2) 87 ; (L3) 74 .The result of this study showed that bloated fish (Rastrelliger kanagurta L.) used to reduce the total blood cholesterol level of male hypercholesterolemia mice (Mus musculus).

Abstract

Validation method of ammonia (NH3) determination in ambient air with the ion-selective electrode (ESI) method has been carried out. The purpose of this study is to determine linearity, accuracy, precision, method detection limits, and selectivity. The performance characteristics of the method are determined using standard ammonium chloride solutions. The instrument used to detect ammonia levels is the ion analyzer. The results in the linearity test show an r2 value of 0.9999. Accuracy test results show recovery values in the range of 88.86 to 100.48%. The precision of this method has a value of % RSD smaller than 2/3 CV Horwitz.. The detection limit value of the method was 0.0224 mg/L. The presence of interference ions such as SO2 and NO2 does not affect the measurement of ammonia concentrations. The results of the validation test show that the method used can be used to determine ammonia concentrations in ambient air.
