Abstract

The research about biodiesel produced from cow's fat using sodium hydroxide (NaOH) as catalyst has been done. Biodiesel produced from cow's fat was done through transesterification process using methanol 1:12 which priory react with 0.3% NaOH as catalyst due to oil and methanol weight. The transesterification process was conducted for 5 hours at 65°C. Biodiesel from cow's fat is characterisized by GC-MS and ASTM (American Society for Testing and Materials) method. Methyl ester which produced from cow's Fat fat are 31.67% of stearic acid, 25.67% of palmitate acid, and 22.68% of oleate acid. Biodisel from cow's fat are qualified as diesel fuel and biodiesel characterisized by ASTM for specific density (0.8705 kg/m3), kinematic viscosity (4,481 mm2/s), flash point (176,5 0C), pour point (21 0C), and Conradson's carbon residu (0.0139% wt).

Abstract

Research on characterization clays from Latuhalat village before and after the activation using ammonium nitrate has been carried out. The brick was grinded, washed with aquadest and filtered. The clays was dried for 4 h in oven at 120°C, then it was soaked in HCl 1M for 30 min and was filtered. The clays in oven at 110°C for 5 h. The clays were sieved and activated using ammonium nitrate solution 700 ppm for 5 hours followed by filtration and heating in a furnace with temperature 5000C for 4 hours. The results of this research show that the adsorption of Pb2+ metal ions by ammonium nitrate salts, activated clays occur at pH 7 with 4 hours of contact time at concentrations of 100 ppm and heavy absorbent 0.15 g. Next clays are not activated NH4NO3 and activated NH4NO3 are characterized by SEM, FT-IR, and XRD. After the adsorption clays are characterized also by FT-IR. SEM micrograph with results on samples of clay before and after activated with magnification 10.000x showed a huge difference. Porosity clay before activation is relatively small compared to clay after activated. Sample after sample surface showed that activated the typical micro-structure is clearly visible in the shape of the flat, and slightly layered hexagonal. FT-IR analysis of clay before and after activation, activation and after adsorption showed the results did not very much. On clay prior to activation with NH4NO3 on the uptake about 900 cm-1 is the functional group montmorilonite. For the clays after adsorption showed the existence of ties between clay particles with metal. For metal uptake there are areas around 425 cm-1. The result analysis of x-ray diffraction of clays before and after activation of NH4NO3 indicates the result value of 2θ in a row is 26,65470 and 26,87750 which is area with indication of quartz SiO2.

Abstract

Polysaccharide from Gracilaria sp (locally known as “Sayur Karang”) was extracted using hot alkaline solutions (NaOH and KOH). Fractionation using DEAE-Sepharose Fast Flow column showed that the polysaccharide discharged after being eluted with 0.5 – 1.0 M NaCl. Spectroscopic analysis using FTIR showed that the polysaccharide contained hydroxyl (3420 cm-1 (NaOH frcation) dan 3446 cm-1 (KOH frcation)), carbonyl (1642 cm-1 (NaOH frcation) and 1644 cm-1 (KOH frcation)) and sulphate (1271 cm-1 (NaOH frcation) and 1262 cm-1 (KOH frcation)) groups proving that the polysaccharide is a sulphated polysaccharide. A further study is needed to elucidate the structure of the sulphated polysaccharide as well as physiochemical properties of the polysaccharide.

Abstract

The research to determine histamine content in bullet of tuna (Auxis rochei) with variation of tamarind (Tamarindus indica L.) extract concentrations and time of marinate has been done. The histamine content is determined quantitatively by using ultraviolet-visible spectrophotometer with the calibration curve method. The result showed that histamine content in bullet tuna marinated in tamarind extract with varied concentrations of 5%, 10%, 15%, and 20% within 10 minutes, are 37.4561, 35.3041, 23.8778, and 22.1186 mg/100 g respectively. While, the concentrations of histamine in bullet tuna marinated in 20% of tamarind extract with variation of 10, 20, 30, 40, and 50 minutes, are 22.2965, 19.7544, 17.6925, 11.5865, and 8.0396 mg/100 g respectively. A qualitatively, visual comparison of colour intensity of samples with reference colour scale of the standard solution concentration can be used to determine concentrations of histamine without the aid of a spectrophotometer.

Abstract

Analysis of histamine content in processed bullet tuna (Auxis thazard) stew flesh can be carried out by Spectrophotometry method, using p- phenildiazonium sulfonate reagent. A qualitative, visual comparison of colour intensity of samples with reference colour scale of the standard solution concentration can be used to determine levels of histamine without the aid of a spectrophotometer. The histamine content is determined quantitatively by the standard curve regression equation (y= 0.003x–0.062) with determination coefficient value (R2= 0.938). The results showed that histamine content inprocessed bullet tuna (Auxis thazard) obtained: 46.9964; 40.3093; 34.4348; 28.9900 and 24.8862 mg/100g fish, at 0.5; 1.0; 1.5; 2.0 and 2.5% concentration of NaCl, respectively.
