east biomass is often used in the fermentation of bread dough. Dough fermentation can be maximized by adding a nitrogen source. This study used yeast isolates from salak pondoh (YIS-3, YIS-4, and ...YIS-7). The purpose of this study was to determine the effect of nitrogen addition on yeast growth and bread quality. This study used an experimental approach. The results of the growth study showed that all isolates treated with 0.05% urea produced higher biomass and cell counts than those treated with control. The highest biomass was produced by YIS-7, which was 3.81 g/300mL, while the highest number of cells was produced by YIS-3, which was 29.02x106 cells/mL. The percentage of proofing results showed that all yeast isolates treated with 0.05% urea needed a longer time to achieve the highest proofing. However, the volume of bread after baking showed better results than those treated with control. The largest volume of bread produced by YIS-3, was 972.14 cm3. The results of the organoleptic test showed that P<5%, which means that all treatments had a significant effect on the taste, aroma, color, and texture of the bread. Overall, the panelists gave good acceptance of the bread fermented by YIS-3 with 0.05% urea treatment. So it can be concluded that the addition of urea with a concentration of 0.05% in YIS-3 gave the best effect on the yeast growth and bread quality.

The mining sector can contribute to the state in the form of foreign exchange and state in the form of foreign exchange and funding sources such as royalties, taxes, the expansion of employment and ...physical development, on the other hand, led to some social and environmental conflicts. One effort to improve environmental conditions in the mining area through revegetation, reclamation and post-mining. Reclamation and post-mining activities must be under the EIA plan, FS, Plans Closure Reclamation and Mine Closure Plan to be used for sustainability and ecotourism. This study was conducted using a collaboration between study literature method and the AHP method. The purpose of this study was to determine the post-mining land use, preferred alternatives for utilization of post-mining land is done through the Analytical Hierarchy Process (AHP) method by analyzing the relationship between three criteria and alternatives. The criteria are selected based on the ecological, socioeconomic and cultural aspects. This is based on the consideration of sustainability and spatial planning. In addition, the alternatives that will be considered as utilization strategies include the efforts to increase the land use.. Secondary data analysis resulted that known to the utilization of post-mining land from various companies such as: the use of pits (void) into water treatment, aquaculture and ecotourism, the usage of land reclamation and mine closure in the form of plateau used as cultivation flora and fauna depends on the utilization zone, which has approved the EIA Document, FS, Plans Closure Reclamation and Mine Closure Plan.
Along with the significant increase of world coal price reaching US$ 100.69/ton, it can be affects the increase of coal production in Indonesia. On the other hand, coal mining activities cause a ...number of social and environmental conflicts..

Coal Production influences the Community Development Cost variable and the effect is positive. Because the regression coefficient on coal production is positive, which means that if the coal production increases, the Community Development costs will increase.The implementation model of community empowerment programs includes increasing infrastructure and infrastructure, Increased real income, and increased economic independence.
Exopolysaccharides get a lot of attention because they can improve the host immune system. Exopolysaccharide is a polysaccharide that is produced and secreted from microbes outside the cell, usually ...found on the outside of the bacterial structure. The Lactobacillus casei group from human breast milk is thought to have the ability to produce exopolysaccharides. The purpose of the study was to examine the exopolysaccharide of the L. casei group that was isolated from breast milk. The methods used include the gravimetric, the phenol-sulfuric acid and the Fourier Transform Infra-Red (FTIR). The results showed that the L. casei group could produce exopolysaccharides, and had high exopolysaccharide total sugar content. Lactobacillus paracasei had the highest exopolysaccharide and total sugar content of 3660 mg/L and 80.6%, respectively. The FTIR results of the L. casei group exopolysaccharides showed the presence of hydroxyl functional groups O-H (3425.76-3295.98 cm-1), methyl C-H (2930.86-2856.70 cm-1), carbonyl C=O (1660.11-1647.27 cm-1), C-H (1456.16-1373.44 cm-1) and C-O-C ether (1071.08-1056.82 cm-1) which are specific characters of exopolysaccharides. Since the FTIR profile demonstrates that the L. casei group can produce exopolysaccharides, it has greater potential as a a probiotic.
