Abstract

African catfish has potential to be processed become sausage because it contained highly protein. Soy protein isolate was use as binder. This research aims was to determined SPI concentration to produce high quality of fish sausage, analyzed the physical characteristics and nutritional value contained in fish sausage, and comparing with commercial sausage. The meat  was washed twice and obtained the yield 18,72%. SPI 13% was selected and gave better result on sausage production. The results of proximate analysis for the ash content of 1,60%, protein of 15,97%, fat of 0,61%, carbohydrate 2,22%, moisture content of 79,6% and the TPC 0.5x101 colony/g. Value of the comparison test objectively for gel strength, water holding capacity and emulsion stability were lower than commercial sausage. Catfish sausage was more preferred the commercial sausage on the parameters folding test, teeth cutting test, smell and taste. Protein and carbohydrate nutrient content of fish sausage African catfish superior to commercial sausage.Key words: frequency of washing, fish sausage, soy protein isolate

Abstract

The research objectives were determine the concentration of lime and soaking time that could reduce the smell of sardine, the concentration of curcumin that could prevent the oxidation of fish, and the effect of curcumin on chemical and microbiology characteristic of sardine abon during 30 days storage. Sardine was soaked in lime solution with concentration from 5 to 20% (v/v) for 10, 20, and 30 minutes. After the best concentration of lime was found, the experiment was continued to determine the optimum concentration of curcumin in maintained he chemical and microbiology characteristic of sardine abon by adding the fish with curcumin from 1% to 5% (w/w). The abon was stored for 30 days andevery 10 days the sensory test, proximate analysis, analysis of water activity (aw), TPC and TBA were carried out. Sensory test showed that the addition of lime until 15% could increase the result, however, the sensory test result depleted when 20% of lime was used. The period of immersion also gave positive correlation with sensory test. The preliminary experiment also showed that the addition of curcumin increased the value of sensory test with 1 and 2% of curcumin gave better result compared with 3, 4 and 5% curcumin. During 30 days storage period, the value of sensory parameters and proximate properties were decrease, meanwhile, the water activity, TPC and TBA were rised. In conclusion, up to 30-day storage period, teh quality of fish abon was decrease,d but still could be accepted by the panelists. Immersion of fish abon on 15% of lime for 30 minutes and addition of 2% curcumin gave better quality of fish abon compared with others treatmen with value of water content 10.71%, ash4.16%, fat 26.82%, protein 30.51%, carbohydrate 27.80%, aw 0.51, TPC 2.45 colonies/ gram, and TBA 1.76mg/kg. The addition of curcumin fish abon did not significantly influence the appearance, water content, ash, fat, and carbohydrates, however the color, aroma, texture, flavor, protein content, water activity (aw), value TBA, and TPC significantly influenced.Keywords: curcumin, fish abon, lime, sencory parameters

Abstract

Petis ikan merupakan komoditi hasil pengolahan ikan yang biasa digunakan sebagai lauk pauk atau campuran makanan rakyat yang khas. Petis ikan memiliki pontensi yang sangat besar dalam pemasaran, namun ada masalah atau kendala pada petis ikan yaitu bau amis yang menyengat. Dalam penelitian ini dipelajari pengaruh penambahan asam-asam organik seperti jeruk nipis (Citrus aurantifolia), belimbing wuluh (Averrhoa bilimbi) dan asam cuka dengan konsentrasi berbeda terhadap pengurangan bau amis petis ikan (Decapterus spp.). Hasil dari penelitian ini menunjukan bahwa penambahan jeruk nipis dengan konsentrasi 15% cukup efektif untuk mengurangi bau amis petis ikan layang dan penambahan jeruk nipis ini tidak mempengaruhi zat gizi yang ada dalam petis ikan.Kata kunci: asam cuka, bau amis, belimbing wuluh, jeruk nipis, petis ikan

Abstract

Peda is one of fermented fish product without further drying process, so it still classified as an intermediate moisture food where the fermentation process is still exist. The objective of research was to know the influence of salt concentration on peda spontaneous fermentation process. The treatment was immersion on salt concentrations (30%, 40%and 50%) with two salting phase. Parameters which observed were pH, water activity (aw), total viable count (TVC), lactic acid bacteria count (LAB) and salt content during 0, 6, and 14 days of fermentation. The changes of raw material and its chemical composition were also analyzed include moisture, ash, protein and lipid, while total volatile basic (TVB) and trimethylamine (TMA) were observed at the end product a long with the sensory test. During the fermentation process, the value of pH, aw, salt content and log TVC decreased, while the BAL total log increased. The proximate analyses showed that the moisture and protein on raw material were 73.91% and 22.01% respectively which higher with the product 52.71-53.94% for moisture and 20.15-21.54% for protein, while ash and lipid raw material were 3,22% and 0,22% respectively which lower from its product 1.25-1.37% for ash dan 15.96-16.90% for lipid. The content of TVB (18.42-16.78mg/ 100 gr) and TMA (3.35-2.23 mg/ 100 gr) of peda were decrease while increasing the salt content (30-50%). The sensory test indicated no significant different result in between all treatments. Therefore, the determination of selected product was based on the result of sensory test eg. 30% salt.Keywords: chub mackerel, fermenstation, peda, Rastrelliger sp

Abstract

Pesawat terbang akan mengalami beberapa gaya akibat adanya distribusi tekanan udara yang terjadi disekitar pesawat. Salah satu gaya yang bekerja adalah gaya hambat (drag). Distribusi tekanan udara tidak hanya dipengaruhi oleh bentuk dari benda tetapi dipengaruhi sudut serang yang terbentuk antara aliran udara dengan benda dan juga kecepatan aliran udara. Dengan menggunakan terowongan angin Suryadarma Low Speed Tunnel WT-400, dilakukan pengujian terhadap kepala pesawat Boeing 777-200 terhadap perubahan sudut serang dan kecepatan aliran. Sebagai perbandingan dilakukan pula pengujian terhadap dua benda yang berbeda. Kata kunci: Distribusi tekanan udara, gaya hambat.
