Abstract

Fish oil could be extrated from lemuru (Sardinella lemuru) or lemuru canning industry byproducts. The fish oil should be refined first before using as omega-3 sources. This reasearchobtained was purification of fish oil from lemuru canning industry by products at Bali usingvariations purification method. The fisrt step was done by analysis of crude oil such of free fattyacids value, peroxide value, and iodine value. Then after the purification process using variationspurification method, the refined fish oil was analyzed for same parametrs. The best refined fishoil was analyzed of composition fatty acid using gas chromatograph (GC) instrument. The resultshowed that the crude oil had free fatty acids value, peroxide value, and iodine value as follows24.03%; 6.97 meq/kg sample; 189.13 g/100 g sample. After the refining process using four methods,the result showed that free fatty acids value, peroxide value, and iodine value became: the firstmethod 24.02%; 6.16 meq/kg sample; 187.91 g/100 g sample. The second method 23.14%; 4.17meq/kg sample; 193.94 g/100 g sample. The third method 9.38%; 4.88 meq/kg sample; 225.39 g/100 g sample. And the fourth method 11.03%; 5.64 meq/kg sample; 222.69 g/100 g sample. Dueto the peroxide value, the refined lemuru oil that could met standard of Indonesian farmacope forconsumed fish oil was resulted from the third method. In the refined lemuru oil could be found ofEPA component (Methyl cis-5,8,11,14,17-Eicosapentaenoic acid methyl ester) with concentration650,65 μg/mL..Keywords: By products, fish oil, refining process, Sardinella lemuru

Abstract

The solid waste from agar processing industries in Indonesia is enormous. The waste contains numbers of macro and micro nutrient including growth hormone that can be a good source for plant fertilizer. Utilization of solid waste obtained from agar processing into fertilizer has been carried out by mixing with Sargassum powder, fish silage and Eucheuma cottonii pasta. Various concentrations of the solid waste (13, 19, 22 and 25%) and the Sargassum powder (0, 3, 6, 9, and 12%) were used in this study to obtain optimum nutrients  in the formulated fertilizers i.e. growth hormone, total nitrogen and potassium. Growth hormone were analyzed using high-performance liquid chromatography (HPLC), while N content by Kjeldahl methods and K content analyzed according  AOAC.The results showed that the optimum formulation was obtained from the combination of 25% solid waste and 0% Sargassum powder, which contained the highest growth hormones i.e. auxins (IAA) 46.75 ppm, gibberellin (GA3) 22.25 ppm, cytokinin-zeatin 18.50 ppm, and cytokinin-kinetin 61.00 ppm. While the potassium content was 0.43±0.001 ppm and the total nitrogen was 0.53± 0.06%. This result meets the requirements of the Minister of Agriculture Regulation No. 261/KPTS/SR.310/M/4/2019 regarding the requirements for total N in organic fertilizer. However, the total K+ does not meet the requirement. Therefore, enrichment with other organic raw material is still needed.

Abstract

Characterization of sodium alginate extracted from two species of brown seaweeds (Turbinaria sp. and Sargassum sp.) harvested from Binuangeun Beach, Banten, has been conducted. The aim of the study was to evaluate physico-chemical characteristics (moisture, whiteness, viscosity, and functional groups) of sodium alginates extracted from Turbinaria sp. and Sargassum sp. Extraction was conducted in acid solution with the following steps: washing, acid extraction, bleaching, alginic acid conversion, sodium alginate conversion, dehydration, and drying. Each extraction was conducted in duplicate using approximately 1 kg of the dry raw materials (Turbinaria sp. and Sargassum sp.). Results of the analysis showed that the yield of sodium alginate powder extracted from Sargassum sp. was 24.56+0.56% (w/w) with moisture content of 12.69+1.24%; whiteness degree of 43.80+1.71%; and viscosity of 143.43+3.25 cPs, while the yield of sodium alginate powder extracted from Turbinaria sp. was 22.69+2.12% (w/w) with moisture content of 14.77+2.55%; whiteness degree of 23.77+0.68%; and viscosity of 133.67­+4.04 cPs. Meanwhile, the commercial sodium alginate was identified to have moisture content of 16.07+0.09%, whiteness degree of 29.37+0.55% and viscosity of 102.67+4.04 cPs. This indicates that physicochemical characteristics of sodium alginate extracted from Sargassum sp. is better than those extracted from Turbinaria sp. and commercial alginate since it had lower moisture content as well as higher whiteness degree and viscosity.
