Abstract

Penelitian ditujukan untuk mengevaluasi pengaruh penambahan tahu  pada bakso belut (Monopterus albus) terhadap penerimaan konsumen. Sebanyak 4 kg daging belut dan 300 g tahu yang diperoleh dari salah satu pasar di Kota Pekanbaru diolah menjadi bakso. Empat jenis bakso dibuat dari daging belut, telur dan tepung tapioka; dan masing-masing difortifikasi dengan tahu 0 g, 50 g, 100 g, dan 150 g. Produk akhir diamati terhadap penerimaan konsumen dan komposisi kimia. Hasil penelitian menunjukkan bahwa bakso belut dengan penambahan tahu yang difortifikasi dengan tahu 100 g adalah yang paling disukai konsumen. Bakso belut tersebut mengandung: air  52,48%, protein 18,35%, lemak 1,347%, dan abu 5,67.

Abstract

This study was conducted in January 2014 in the waters of Tanjung Balai Asahan Subdistrict Bagan Asahan. The purpose of this study was to determine the content of heavy metals Pb, Cu and Zn that are present in flesh and shells by size, to determine the relationship of heavy metal content in the meat and shells of different sizes and to determine the feasibility of shellfish (M. meretrix)consumption. Content of heavy metals Pb, Cu dan Zn in shellfish (M. meretrix) was analyzed by the dry method used by et all. (2003) The results showed that Pb content in the shell was higher than in the flesh(sig.<0.05), while Cu and Zn higher in the flesh than in the shell(sig.<0.05). Based on body size, Pb in flesh washigher in medium size (1.16 mg/g) and for the other metals were higher in largersize, namely Cu (24.57 mg/g) and Zn (1619.17 mg/g). In the shell, for Pb and Cu were higher in largersize, namely Pb (5.50 mg/g) and Cu (12.33 mg/g), while Zn was higher in small size (434.58 mg/g).Keywords: Pb, CuandZn; M.meretrix; Bagan Asahan

The research used survey method. Sample were taken in three stations, namely station 1,station 2 and station 3. Sampling vertical based on depth, at surface, 2,5 secchi disk and in thebottom. The parameter of water quality measured pH, temperature, nitrate, phosphate, depth,transparancy, and dissolved oxygen (DO). The result shown concentration of dissolved oxygenrange 2,04-5,29 mg/L, concentration of nitrate range 0,02-0,34 mg/L and the concentration ofphosphate range 0,01-0,71 mg/L. The value of temperature was 28,50C, depth range of 145-302cm. The value of pH was 5. the parameters of water quality were observed still support theaquatic organisms..Keywords : dissolved oxygen, the vertical profile, Pinang Dalam Oxbow

Abstract

This study was conducted to evaluate the effect of different HCl concentrations on gelatin properties extrated from tuna eye’s. About 13 kg tuna eye’s were taken from PT. Dempo Andalas Samudera, West Sumatera. Tuna eye’s was diveded into 3 groups and each group was extracted for its gelatin using HCl solution at different concentrations (4%, 5% and 6%). The extracted gelatins were evaluated for yield, pH, proximate composition and isoelektric point. The yield and pH of the gelatin were 0,28%-0,71% and 3,11-3,89 respectively. The yield and pH of the gelatin increased as the increasing of HCl concentration; and the yield and pH of the gelatin extracted using 4% HCl resulted in the best quality product. Protein, fat, moisture, ash and isoelektric point of the best gelatin were 85,76%; 4,76%; 1,87%; 5,06%; pH 7,5 respectively.Keyword: Gelatin, eye’s tuna, HCl Solution.
