Sitimardiyahfix2@gmail.com Prodi D3 Analis Kesehatan UM Surabaya   Abstract Fermented milk is one of dairy products, obtained by fermentation of milk by certain microbes to produce lactic acid. In general, fermented milk stored at a temperature of 50C cooler cupboard to inhibit acid formation by bacteria is still alive, so as to avoid excessive formation of a sour taste. During storage of fermented milk pH decreased continuously. At a temperature of 100C, the damage began to emerge after 3-4 days of storage, which is a sour, watery, and the accompanying changes in the original tender texture and cause contamination between certain bacteria that cause alcohol. Based on the above formulation of the problem can be taken "Is there any effect of fermented milk storage time in the freezer for alcohol content? ". The purpose of this study was to investigate the effect of storage time of fermented milk in the fridge for alcohol content. This research is a type of observational analytic studies because there is no treatment of the researchers aimed to determine the effect of long storage of fermented milk in the fridge for alcohol content. The sampling technique used is random sampling, totaling 5 samples at each storage time. Research variables consisting of the independent variable storage time, and the dependent variable is the alcohol content. The level of alcohol is done in fermented milk after being stored for 1 week, 2 weeks, 3 weeks, and 4 weeks using the method five times Pycnometer with replication. From the results of this study the mean increase in the alcohol content of fermented milk on each storage time is 1 week, 2 weeks, 3 weeks and 4 weeks. Having performed using ANOVA statistical test obtained p = 0.000 (p <0.05) can be summed Ha Ho is rejected or accepted, which means there is the influence of storage time of fermented milk in the fridge for alcohol content.   Keyword : fermented milk, alchohol level
