Abstract Jerky is a traditional food made from sliced or minced meat that were marinated in spices and dried to extend its shelf life. Most of the marketed jerky available in Sumbawa were half-cooked. Theaim of this study was to determine the concentrations of Lactic Acid Bacteria to chemical and sensory characteristics of buffalo jerky. A laboratory experiment was conducted andusing Completely Randomized Design with asingle factor namely LAB concentrations (P1=0%, P2=0.5%, P3=1% and P4-1.5%). Data was analyzed using Co-Stat software at 5% significance level.The results showed that the LAB concentrations gave significant differences on water content, protein, fat, color, flavor and texture of fermented buffalo jerky, but gave non-significant difference on the ash content. The best LAB concentrations were 0.5% that resulted on jerky with protein content of 74.32%, fat content of 6,37%, water content of 12.51%, ash content of 1.14%, also color, flavor and texture that were acceptable to panelists.

Jruek drien is one of traditional fermented food of Aceh. This product made from flash of durio that fermented without starter addition. Explorative research has been conducted to examine the change of chemical and microbiological characteristics of jruek drien during fermentation. This study used completely randomized design with single factor (length of fermentation: 1,3,5 and 7 days). The parameters analyzed were water content, pH, total acid, total sugars, total lactic acid bacteria and yeast. The results showed that water content and acid total were increased while pH and sugar content were decreased. The highest total of lactic acid bacteria was found on day 3. Yeast detected only on early fermentation and no detected on 7th day.

THE CHEMICAL QUALITIES OF FERMENTED DUCK IMMERSED WITH DIFFERENT LEVELS OF L. plantarum AND STORED UNDER LOW TEMPERATURE. The objective of this research was study the effect of soaking time on chemical (pH, water content, acetic acid content and total lactic acid bacteria) of duck meat fermentation using L. plantarum. Ducks was done by soaking duck meat in culture L.plantarum and stroraged at cooling temperature. Soaking was done with different level of L. plantarum. This experiment was arranged in a completely randomized design consisted of five levels of L. plantarum. Data were analyzed by variance analysis. Significantly difference treatment effects on variable measures were tested using honestly significant difference (HSD). The result showed that treatments had significantly difference (P<0,01) on pH and total lactic acid bacteria of duck meat fermentation, but did not affect significant (P>0,05) on water content and acetic acid content of duck meat fermentation. Therefore, it can be concluded that soaking at 15% level of L. plantarum and storage at cooling temperature can conserve duck meat until 16 days and ducks fermentation were still constant. Keywords: Fermentation, duck meat, pH, water, acetic acid, lactic acid.

Analyze of acidity and amount of lactic acid bacteria of yogurt made from different milk types and lactobacillus casei percentageABSTRACT. The objective of this experiment is to determine the effect of milk types and percentages of Lactobacillus casei as a starter to the amount of Lactic Acid Bacteria in yogurt and its pH value and Lactic Acid value.  Factorial Completely Randomized Design with two factors and three replications was applied.  The A factor was the milk types that were a1 = Powder Milk, a2 = Fresh Milk and a3 = UHT milk.  The B factor was the percentages of Lactobacillus casei  (b1 = 5% and b2 = 10%).  Parameters observed were the level of lactic acid, the pH value of yogurt and the amount of lactic acid bacteria.  The result showed  significantly difference (P0.01) from the use of milk types and Lactobacillus casei percentages on the lactic acid level, and there are no interaction between factors.  There was also significant different (P0.01) showed from pH value and an interaction between both factors was presented.  In addition there was significant difference (P0.05) showed by the amount of lactic acid bacteria, and an interaction between both factors was also existed.  The research concluded that the higher the percentage of starter, the higher the level of lactic acid and the amount of lactic acid bacteria of yogurt that made from all milk types.  On the contrary, the higher the percentage of starter, the lower the pH value of yogurt.

This research was conducted to determine the effect of kweni mango juice addition and percentage of Carboxymethyl Cellulose (CMC) on the physicochemical characteristics of watermelon albedo fruitghurt. The research used completely randomized design with two factors, i.e the addition of kweni mango juice (12.5%, 15.0%, 17.5%) and percentage of Carboxymethyl Cellulose (CMC) (0.3%, 0.5%, 0.7%). The results showed that kweni mango juice addition and percentage of Carboxymethyl Cellulose (CMC) had highly significant effect on ash content, vitamin C content, total lactic acid bacteria, and viscosity. The addition of kweni mango of 17.5% and 0.7% of Carboxymethyl Cellulose was the best treatment, based on the parameters of ash content, vitamin C content, total lactic acid bacteria, and viscosity. The antioxidant activity of fruitghurt with the best physicochemical characteristics was analyzed. The results showed that it was 75.15 µg/mL.

ABSTRACT               This study aims to determine the effect of Lactobacillus plantarum bacterial starter concentration on some quality of the porang flour. This study used experimental design one-factor Completely Randomized Design (CRD) consisted of BAL concentration (KB) of Lactobacillus plantarum with 6 treatments which is 0%, 5%, 10%, 15%, 20% and 25%. Each of treatment were repeated three times to obtain 18 unit samples. Data from observations were analyzed using analysis of variance (Analysis of Variance) at 5% significance level using Co-stat software. If there are significant differences, a further Polynomial Orthogonal and Honestly Significant Difference (BNJ) test is performed at a level of 5%. The parameters observed included pH value, protein content, water content, yield, total lactic acid bacteria, organoleptic parameters of color and aroma (hedonic and scoring). The results showed that the concentration of Lactobacillus plantarum bacterial 20% was the best treatment in producing porang flour, pH value 5.72, protein content 6.49%, yield 9.33%, total lactic acid bacteria 6.66 log CFU / g and color rather brown and slightly acidic aroma and somewhat preferred by panelists.

Cookies is one type of populer biscuits. The basic ingredients of cookies are generally wheat flour. The availability of wheat flour in Indonesia is dependent on imports. To overcome this, the substitute of wheat flour is needed. Alternative materials can from tubers one of them is a black potato. The objective of this research were to substitute wheat flour with black potato starch for cookie manufacture and to analyze chemical composition and physical properties of cookies. The design used was Completely Randomized Design (CRD) with flour flour treatment: black potatoes are 100%, 90%: 10%, 80%: 20%, 70%: 30%, 60%: 40%, and 50%: 50%. The addition of black potato starch cause a decrease in water content, protein content, fat content and increased ash content of cookies. The addition of potato starch up to 30% produces the preferred cookies that accepted by panelists.Key words: Coleus tuberosus, cookies, wheat flourABSTRAKCookies (kue kering) merupakan salah satu jenis biskuit yang banyak disukai oleh masyarakat dari berbagai kalangan.

The oci fish used are fresh oci fish from the fish market in Gorontalo, then fermented for 0, 3, 10 and 15 days. The research method used the experimental method through a complete randomized design pattern using variance analysis followed by the Duncan test. For 15 days fermented, the pH value, water content and microbial total decreased, but the protein content and the number of lactic acid bacteria increased. The bakasang of oci at the end of fermentation has a total lactic acid bacteria of 2.51x107 CFU/g, the water content of 65.56%, the protein content of 5.98%, and pH value of 6.0.
