Abstrak: Chickens meat is inclusive of food substance that easy to destroy or rotten. Breast meat will be the focus in this research. Long time of postmortem affected decrease of meat quality especially on physical properties. The acceptability of poultry muscle as food depends largerly upon chemical, physical and structural changes that occur in muscle as it converted to meat. This experiment was carried out to investigate decrease of meat quality (physical properties) in various time of postmortem.The aim of this research is to learn meat of chickens physical properties at various long time postmortem (0, 2, 4, 6 and 8 hours) and to know meat quality until 8 hours postmortem. Completely Block Randomized Design was used in this experiment. Treatment of this experiment is time of postmortem (0, 2, 4, 6 and 8 hours) and different day at slaughtering as block design consist of three block. If any significant different (p<0,05) betwen treatments were than compared by using contrast polinomial orthogonal test. The observed variable are pH, water content, water holding capacity (WHC) and water activity. The results shows that long time postmortem affected to water content value, and very affected to pH value, and water activity, but not affected to water holding capacity. This research shows that long time postmortem 0 – 8 hours results that pH mean ranged from 5,76 – 5,4, water content ranged from 74,50 – 73,90, WHC mean ranged from 95,27 - 93,75 and water activity ranged from 0,985 – 0,960. Average value on pH, water content and water activity changes following linier pattern with correlation coefficient are negatively. This mean that long time postmortem will be decreasing pH value, water content value and water activity value.

Judul: Kualitas Mikrobiologi Karkas Ayam Broiler pada Berbagai Lama Postmortem
Abstrak: Carcass of broiler chicken is one of the food products that rich of nutrition, so it is easy to spoiled and contaminated by microorganism. Contamination could be happened at farm, in slaughtering process and after slaughtering process. This research is aimed to study about microbiological changes of Total Plate Count (TPC), Coliforms, existence of Salmonella and pH value from carcass of broiler chicken at the various postmortem time (0, 3, 6, 9 and 12 hour). The method that used is rinse and swab. The observed parameters include, Total Plate Count, Coliforms, existence of Salmonella and pH value. The experiments design that used is Complete Block Randomized Design with 5 treatments and sampling time as group. TPC, Coliforms and pH value were analyzed by ANOVA (Analysis of Variance), and if there is a significant effect, it further analyzed by polynomial orthogonal. Data about existence of Salmonella was analyzed descriptively. The result showed that postmortem time give a significant effect (P< 0.05) for pH value and Coliforms, (P< 0.01) for TPC from surface of carcass and not significant effect for TPC from cavity of carcass. It means that the longer postmortem time, TPC and Coliforms count are increase, but it was decrease to pH value. The pattern that formed from the results is linear function. S. enteritidis is found in cavity broiler chicken carcass during cognition.
