Against Total Microbes Flying Fish and Tuna In Room Temperature Storage JF - Jurnal Pengolahan Hasil Perikanan Indonesia JA - JPHPI VL - 23 IS - 3 SE - Articles DO - 10.17844/jphpi.v23i3.32611 UR - https://jurnal.ipb.ac.id/index.php/jphpi/article/view/32611 SP - 523-531 AB - Fish as a food ingredient contains various bioactive compounds and decays quickly at ambient temperature which is indicated by the presence of microbial growth called TPC. External efforts to extend shelf life, conducted research aimed to determine the effectiveness of Gracilaria sp .. extract against the total microbes of flying fish and tuna at ambient temperature at 8, 12, 24, 36, 48 and 72 hours. The research method was descriptive qualitative. using Gracilaria sp. extract with a concentration of 3%. The test parameters include the total plate count (ALT) with the plate system and the water activity test based on the partial vapor humidity in the material (fish) against pure vapor pressure. The effectiveness of Gracilaria sp. The best 3% in fish storage at the 36th hour with total number of microbes that grew of 2.35 log Cfu /g in flying fish and 2.35 log Cfu/g in tuna. The effectiveness of Gracilaria sp. potential to inhibit the total growth of fish bacteria. Storing raw fish for fresh flying fish is 0.39 and with extract is 0.52. The standard deviation of fresh tuna is 0.59 and with extract is 0.56. Results the number of microbial contaminants found in flying fish and tuna has not exceeded the microbiological quality standard for fresh fish, namely 5x10⁵ CFU / g (5.70 log Cfu / g). ER -
