The purpose of this study was to determine the interaction of adding spices and storage time to the total number of microorganisms in pasteurized milk and its feasibility. The ingredients used were 7.4 l of fresh cow's milk, 0.5 kg of sugar, 37 g of powdered ginger, 3.7 g of cinnamon powder, 37 g of turmeric powder, and aquades. The first step in making pasteurized milk is filtering fresh milk, then dividing the milk into two parts. The first part is made into pasteurized milk without the addition of spices, the second part is made into pasteurized milk with the addition of spices. When the second part of the milk reaches a temperature of 40°C then the spices are mixed into the milk until well blended. If the temperature reaches 63°C for 30 minutes, then turn off the heat and wait for the temperature of the milk to drop. Then the milk is packed into 100 ml bottles. The packaging of the first part of milk without the addition of 37 sample bottles of spices and the second part of pasteurized milk with the addition of 37 sample bottles of spices. Total Plate Count (TPC) test used a factorial completely randomized design (CRD) with four repetitions. The data obtained were then processed by analysis of variance ANOVA, to determine the interaction between milk with the addition of spices and different storage times. The results of the TPC test showed that the addition of spices to pasteurized milk had no significant effect after pasteurization was carried out (P>0.01) but had a significant effect (P<0.01) on the total microorganisms in different storage times. The results of the calculation of economic analysis show that a Break Even Point (BEP) with a profit of 10% produces a BEP unit of 485 units of BEP of 6,270,000 rupiah and reaches the break-even point at 0.3 months. The profit per day is 86,950 rupiah with 312 working days, the net profit per year is 27,128,400 rupiah and the time needed to return the initial capital is 0.03 years.

Sausage is a product made from minced meat and then mashed and seasoned, put in artificial packaging, with or without cooking.) due to both oxidative and microbiological damage. Chicken feet are a by-product of chicken slaughterhouses (RPA) whose use is limited because they contain a lot of bones and a little meat, but have a high skin content. The chicken leg consists of several parts such as bone, skin, muscle and collagen. Chicken claw contains collagen of 22.94%. In this study there were 7 stages, namely making gelatin, making kaffir lime oil, making samples, dividing samples, organoleptic tests, hedonic tests, and data analysis. The results of this test indicate that beef sausages coated with edible film with the addition of kaffir lime leaf extract are declared fit for consumption. Because this value is still below the total microbial standard according to SNI (1x106 CFU/g), so beef sausage is still suitable for consumption.

One of the livestock products that are widely consumed by the public is milk. Processed milk products are preferred by the public compared to fresh milk, one of the causes is the case of lactose intolerance. This research aims to determine the chemical quality of dairy products, namely yoghurt added with carica juice with different concentrations of addition. The method used in this research is an experiment starting from the preparation stage, sample making, laboratory tests, and data analysis. The treatment used was different concentrations of juice addition of 0%, 10%, 20%, 30%, and 40%. The results showed that the addition of carica juice had a significant effect (P<0.05) on the content of lactose, protein, fat, solid non fat, and density but had no significant effect (P>0.05) on pH and total solid. The findings of this research were that lactose, protein, solid non fat, and density increased with the addition of carica juice concentration in yoghurt. It is inversely proportional to the fat content which decreases with the addition of carica juice concentration. The conclusion of this research is the addition of carica juice of 40% to yoghurt as the optimal addition of other treatments that have high protein content and low fat content.
