Fish Protein Hydrolysate

Fish is one of the most important foods in the human diet because of its high nutritional quality. One of the potential local foodstuffs in Grobogan is Nile tilapia (Oreochromis niloticus). Nile tilapia has a high nutrient content, especially protein. To obtain better benefits from fish protein, it can be processed into fish protein hydrolysate (FPH) products. Fish protein hydrolysates (FPH) which contain a mixture of small protein or peptides and free amino acids are beneficial for children diet, in preventing and combating malnutrition problems through readily absorbed essential amino acids. This study aimed to analyze the amino acid profile of Nile tilapia and fish protein hydrolysate (FPH) from Nile tilapia. The treatments included processing Nile tilapia into hydrolysate and analyse amino acids of Nile tilapia before and after hydrolysate. The process of making FPH uses a local microbial protease enzyme from Bacillus licheniformis. Amino acids composition was analysed using an internal method developed by Saraswanti Indo Genetech laboratory (18- 5-17/MU/SMM-SIG, UPLC). Data were analysed using the paired t-test statistical test. The results showed there were significant differences in the rate of all amino acid profiles (p<0.05), except L-Aspartic Acid, L-Tyrosine and L-Histidine (p>0.05). From the research, it can be concluded hydrolysate processing has an effect on the increase of Lglutamic acid and L-lysine amino acid.

This study aims to apply vaccination against bacterial disease. The purpose of vaccination is to trigger the immune respone both non-specific and specific of fish against bacteria Motile Aeromonas Septicaemia (MAS) caused by Aeromonas hydrophila. The vaccination for fish with different ages: 2-3 weeks and 5 weeks were done using immersion method. The fish were re-vaccinated (booster) after two weeks of the first vaccination. The survival rate was < 50 % for juveniles 2-3 weeks and > 50% for juveniles 5 weeks. Survival rate for juveniles 5 weeks was higher than juveniles of 2-3 weeks. This shows that organs of juveniles of 5 weeks were more complete than the 2-3 weeks juveniles. The age of fish is one of the important factors for successfully vaccination. Penelitian ini bertujuan untuk melakukan penerapan vaksinasi terhadap penyakit bakterial. Vaksinasi ditujukan untuk merangsang respon kekebalan non- spesifik dan spesifik pada tubuh ikan terhadap penyakit Motile Aeromonas Septicaemia (MAS) yang disebabkan oleh bakteri Aeromonas hydrophila. Vaksin diberikan pada benih ikan nila yang berbeda umur yaitu 2-3 minggu dan 5 minggu dengan menggunakan metode perendaman. Ikan divaksinasi ulang (booster) setelah 2 (dua) minggu dari vaksinasi yang pertama. Prosentase kelangsungan hidup < 50 % untuk benih umur 2-3 minggu dan > 50% untuk benih umur 5 minggu. Jumlah kematian benih umur 2-3 minggu lebih tinggi dari 5 minggu. Hal ini menunjukkan bahwa fungsi organ benih umur 5 minggu telah lebih lengkap dari pada benih umur 2-3 minggu. Umur ikan merupakan salah satu faktor penting penentu keberhasilan suatu kegiatan vaksinasi.
