NETRALISASI MINYAK HATI IKAN CUCUT PISANG (Charcarinus falciformis) MENGGUNAKAN NaOH

Silky shark liver was 10-15% of its body mass and 50% of oil is contained in the liver. The aimed of this study was to determine heavy metal content, fatty acid profile on raw material, extraction of its oil, and parameter of oxidation. The method of heavy metal test stated on the SNI and fatty acid analysis referred to AOAC. The extraction was oven methode at 50, 60, 70, and 80°C in 8 hours. Cadmium (Cd) as the highest heavy metal content with 0.88±0.01 ppm, SFA was 18.46% composed by palmitic acid dominantly (12.59%). The MUFA was 24.54 % with the highest oleic acid (17.86%). PUFA was 19.11 % that consist of DHA (14.35%) as the most abundantly present while EPA was 1.50%. Shark liver oil which was extracted at 50°C had the highest yield (24.47%). The oxidation of silky shark liver oil extraction indicated the best treatment at 50°C with peroxide value (PV), p-Anisidine value (p-AV), percentage of free fatty acid (% FFA), acid value (AV), and total oxidation (TOTOX) were 7.26±1.27 mEq/kg, 16.79±0.28 mEq/kg, 5.47±0.12%, 10.88±0.25 mg KOH/kg, and 31.31±2.26 mEq/kg respectively.

The purpose of this research is to know the fatty acid composition and heavy metal content of soy sauce snail (Bellamya javanica), which is fermented for seven days with addition of 1.5% bromelin enzyme and papain1% enzyme. The fatty acid composition of soy sauce was analyzed by Chromatography Gas and heavy metal content (Cu and Pb) using AAS. The results showed that the fatty acid component as one of the volatile components in soybean snacks was identified by 8 types of fatty acids, namely caprylic acid, lauric acid, myristic acid, palmitoleic acid, linoleic acid, linolenic acid and dominated by the components of palmiic acid and stearic acid. The soybean snail sauce with a combination of bromelin enzyme treatment of 1.5% and 1% fermented papain enzyme for seven days showed negative contaminated Cu, but positively polluted by Pb 2,285 ppm.

Negative Impacts

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.

Crude Fibre

Among the oilseed Brassica crops, Indian mustard [Brassica juncea (L.) Czern and Coss.] is an important source of oil from a nutritional point of view. The nutritional value of oil and cake quality is governed mainly by the composition of its fatty acids, iodine value, saponification, acid value, glucosinolates, crude fibre, protein and limiting amino acids, etc. Seventeen varieties/strains of Indian mustard were taken for saturated and unsaturated fatty acid analysis. The eicosenoic was absent in genotype (NUDBYJ-10) and erucic acid (NUDBYJ-10, LES-46 and Pusa mustard- 21). The fatty acid composition found a variable in different genotypes. Saturated fatty acid, Palmitic + Stearic ranged between 2.3 to 6.5%, Oleic 10.6 to 40.7%, Linoleic 16.1 to 37.7%, Linolenic 13.3 to 26.7%, Eicosenoic 0.00 to 10.30% and Erucic acid 0.00 to 47.50%, respectively. Alternaria blight severity also varied in different genotypes and ranged between 18.75 to 56.25%, maximum being in genotype Kranti and minimum in LES-47. No significant correlation was observed between the fatty acid composition and disease severity. The oil content range from 38.1 to 42.60% and protein content was found highest in variety RGN-73. The amino acid viz. methionine and tryptophan range between 0.41 to 1.81 g/16gN and 0.41 to 1.81 g /16g N, respectively.
