The aim of this study was to evaluate sensory properties and respondents’ preference of yogurt-like set and yogurt-like drink with various Indonesian indigenous probiotic strains produced by dairy industry. Indigenous probiotics of Lactobacillus plantarum MUT-7 and Lactobacillus plantarum DAD-13 were used to produce yogurt-like set and yogurt-like drink. Family perception toward yogurt-like drink was performed in Yogyakarta involving 100 family members. The yogurt-like products were also compared to yogurt containing commercial Lactobacilus bulgaricus and Streptococus thermophilus or commercial yogurt produced by dairy company. Several sensory evaluation toward sensory properties and panelist’s preference were performed in different cities. The result showed that the indigenous probiotic L. plantarum DAD-13 and L. plantarum MUT-7 were potential to be used as a starter culture for the production of yogurt-like set and yogurt-like drink. The combination of indigenous probiotics and indigenous lactic acid bacteria S. thermophilus DAD-11 resulted in better sensory properties of yogurt set compared to combination of L. bulgaricus and S. thermophilus.

Probiotic needs a ‘vehicle’ for their specialized actions in gastrointestinal tract. In this research, tape ketan was used as ‘vehicle’. The objective of this research was to produce probiotic tape ketan powder as an ingredient of functional beverage. Tape ketan used in this research was made by fermentation of glutinous rice with ragi and supplemented with Lactobacillus plantarum Dad 13 (107CFU/g glutinous rice). Probiotic powder was obtained using spray dryer with inlet temperature of 90oC with the addition of 35% maltodextrin. The powder was reconstituted into water with addition of pectin and sucrose. The results showed that viability of lactic acid bacteria and L. plantarum decreased after drying (0.82 and 0.90 log cycle respectively) with viable count from 1.29x1010 CFU to 1.96x109 CFU for lactic acid bacteria and from 1.04x1010 CFU to 1.32x109 CFU for L. plantarum. To obtain probiotic tape ketan beverage, 20% tape ketan powder (w/v), 0.5% pectin (w/v) and 4% sucrose (w/v) were reconstituted. Tape ketan powder which was supplemented with probiotic Lactobacillus plantarum Dad 13 is potential as an ingredient of functional beverage (from the viability after drying).

However, many rivers are polluted from both domestic and industrial waste today. Domestic waste comes from households and industrial wastes from nearby industrial activities. One of the biotas of the river is the fish. The objective of the research was to evaluate pollutant and pollutant index in the watershed and the present of Pb in fish in the watershed. The location of this research was a long Garang watershed Semarang, namely from upstream to downstream of the river. The sampling area was divided into 7 segments based on Central Java Governor Regulation No. 156/2010 based on water designation. The studied parameters in this research were heavy metal in fish and water quality. The studied fish was Nila fish (Oreochromis sp.). Results show that Cu was the main pollutant in water river class 1, 2, 3 and 4. DO exceed the limit parameter in water river class 3 and 4. Finally, the highest heavy metals found in fish were found in Pb, while the water pollution index was due to exceeding Cu, all of which came from industrial waste.

Authors:Muhammad Nur Buwono, Bambang Sigit Amanto, Esti Widowati Pages: 30 - 42 Abstract: Amylose content related to the glycemic index, the higher the content of amylose the lower the glycemic index thus good for diets. Starch modification through fermentation using lactic acid bacteria can be used to increase amylose. In this experiment, modification of Square banana (Musa balbisiana) flour was conducted using Lactobacillus fermentum at certain concentration and fermentation time. This study used a Completely Randomized Factorial Designs (CRFD) with variation of fermentation time (24 hours, 48 hours, 72 hours) and concentration of bacteria starter (0.125%; 0.250%; 0.375% v/v) as the factor. Data were statistically analyzed using Two-Way ANOVA. The results showed that the variation of fermentation time and concentration of starter change physical, chemical, and sensory characteristic of the flour. Water absorption, protein content, and amylose content were increased. However whiteness index, swelling power, solubility, and moisture content were decreased. Pasting properties was change significantly after this modification process. Meanwhile, antioxidant activity and sensory characteristics did not significantly change. In conclusion, the characteristics of the modified flour offer opportunities for the development of square banana flour-based food products with high amylose which good for the diet.

Authors:Anggita Nugrahanto, Supriyadi Supriyadi, Yudi Pranoto Pages: 43 - 53 Abstract: Rice is considered as staple food that consumed in the form of steamed rice. Due to the emergency condition, like volcano eruption or flood, the availability and accessibility might be a serious problem. Therefore, a ready-to-eat rice is necessary. It would need a design processing condition to produce practical cooked rice in more economically packaging with different method.Normal packaging and vacuum packaging of cooked rice followed by steaming for 60 minutes was conducted in this study. Two different storage temperatures include cold and room storage in day 0, 1, 4, and 7 was used to evaluate. The result showed that vacuum packaging gave better reduction in microbial parameter. However, panelist gave same preference in both normal and vacuum packaged cooked rice. Overall, cold stored-packaged cooked rice gave better quality than room stored-packaged cooked rice, especially in microbial parameter. Thus, combination of vacuum packaging and cold storing could be an alternative way to produce cooked rice which can be consumed in difficult condition.
