The purpose of this study was to get a result from the use of liquid smoke coconut shell as a preservative in a product of beef sausage that will increase shelf life, as well as to define the type of grade liquid smoke (grade I or grade II) most optimally utilized as a preservative in a product of beef sausage , The research consisted of two stages: a preliminary study to determine the shelf life of beef sausage standards based organoleptic control is 2 days at room temperature, water content of 71.03% and a total amount of microba is 2,04 x 103 microbial colonies / gram. The main intensive search conducted for estimating the shelf life of sausage with the addition of liquid smoke at a temperature of 200C, 250C, 300C, and 350C with the measured variable are the water content and total microbial count (TPC) were processed using the Arrhenius method. The results showed that the shelf life is based on water content of beef sausage with the liquid smoke longest grade 1 is at a temperature of 200C for 2.7 days while the second grade is 3.08 days, the shelf life based on the total number of microbes on beef sausages with liquid smoke grade 1 at a temperature of 200C for 3.09 days and 3.12 days for grade 2. Liquid smoke  better use grade 2 to the shelf life of sausage.

AbstractThis study explores the impact of human trampling on moss and lichen dominated communities of Maritime Antarctica. A simulation of trampling was performed on previously unaffected plots of different terricolous cryptogamic assemblages at Byers Peninsula, Livingston Island. The communities studied were: 1) a uniform moss carpet, 2) a heterogeneous moss assemblage composed of hummocks and turfs, and 3) a fellfield lichen community. All communities analysed were extremely sensitive but different denudation processes were observed. None of the plots maintained 50% of initial coverage after 200 pedestrian transits. Even very low trampling intensity resulted in disturbance at all plots. Sensitivities of the different communities were identified in order to formulate recommendations for minimizing the trampling impacts. In our study the lichen dominated community on dry exposed soils exhibited the lowest resistance to trampling. For moss communities, lower resistance was found in peat soils with higher water content and biomass. With the current trend of increasing human presence in Antarctica, we predict that the cumulative impacts of trampling over future decades will adversely affect all types of moss and lichen communities.
