Abstract
Food-borne diseases are mainly caused by germs contaminated food which deliver serious illnesses such as intoxication, infection or combination of both. The germs could be Escherichia coli and Staphylococcus aureus. Previous study revealed Saccharum officinarum baggase competence in depressing these bacteria growth. Leaf should afford a better role for having no carbohydrate deposition. For that reason, its petroleum ether extract was prepared in a dilution series of 100 %, 75 %, 50 % or 25 % and used for antibacteria evaluation by paper disc method. The result indicated diminished growth of both bacteria by 100 % and 75 % extract, though not as effective as the positive control containing ampicillin. Furthermore, the Gram-positive bacteria was deprived more than the negative one. GCMS chromatogram depicted some fatty acid appearances that might contribute to the antimicrobe activity. A future study of antibacterial effect of each isolated compound should be managed. However, this study has already verified that the petroleum ether extract of Saccharum officinarum leaves were found to be an antibacterial agent against Escherichia coli and Staphylococcus aureus.

Abstract
Vibriosis is one of the major problems in prawn aquaculture leading to a significant loss in yield. The objective of the study was to isolate and identify the etiological agent of vibriosis from the giant freshwater prawn (Macrobrachium rosenbergiii) aquaculture. The study was conducted by isolating the bacteria using selective media of thiosulfate-citrate-bile salts-sucrose (TCBS) agar followed by the morphological and biochemical characterizations, i.e., indole, methyl-red (MR), Voges-Proskauer (VP), citrate, urease, NaCl 0%, gelatinase and lysine decarboxylase tests. The isolated bacteria were further assayed for their standard growth-curve as well as the ability to form a biofilm on Congo-red agar (CRA). The results showed that the bacteria showed a yellow color in colony appearance and had negative Gram staining. On the biochemical assays, the isolates showed positive reactions on the indole, MR, VP, gelatine, and lysine decarboxylase; but had negative reactions on the citrate, urea, and NaCl 0% tests. The isolates were then identified as Vibrio alginolyticus and after further characterization, the isolates showed the ability to form a biofilm. This result signifies the urgency to overcome V-. alginolyticus as the causing agent of vibriosis that was able to form a biofilm on the giant river prawn aquaculture.

Abstract
Tempe is a cheap and popular food that can be processed into yogurt as an alternative to cow’s milk. Tempe yogurt, which enriched with probiotics is an alternative beverage that able to increase body health. This study was to investigate the nutritional characteristics of tempe and nutrient content of yogurt tempe products. The sample of this study consist of eight test groups, cow milk yogurt (C1), juiced tempe yogurt (C2) and tempe yogurt, which was made using cow milk and varying amounts of tempe flour, 2.5% (T1); 5% (T2); 7.5% (T3); 10% (T4); 15% (T5) and 50% (T6) respectively. Each samples were prepared to proximate compound and antioxidant analysis and organoleptic test to determine the highest nutritional yogurt and most preferred taste. According to the test results, the highest carbohydrate, protein and lipid content were found in the T3 group, which reached respectively 12.21%; 11.72%; 24.46% while the antioxidant value reached 53.93%. Meanwhile, based on organoleptic test using hedonic scale for the highest value of taste preferences, showed that the most preferred taste was T2 group (4.39 point). The addition of tempe flour increases the nutritional value of yogurt in general. It caused by fermentation process of tempe, which releases nutritional compounds in soybeans. According to panelist, the T2 sample became a favorite one, because it has a softer milk texture, a balanced and more fragrant flavor. The conclusion is, the additional tempe flour in yogurt can increase nutritional value and preferred taste.

Abstract

Macrotermes gilvus Hagen (Blattodea: Termitidae) is a common mound-building termite species found in South East Asia regions, particularly in Indonesia, Malaysia, Singapore, Philippines and Thailand. However, scientific information on their demography and mound construction in Indonesian natural forests had not yet reported. This study aimed to investigate the demography and mound construction of M. gilvus Hagen in Yanlappa forest, which represents low-land natural forest in West Java, Indonesia. Termites mound distribution survey was conducted in strip transect, 50 m width interval, and supported by Global Positioning System. Termites population in each mound was determined after dismantled of the mounds, meanwhile mound construction were observed vertical as well as horizontal section. The mound of M. gilvus was distributed clusterly with density of 5 mound/Ha, density mainly located at elevation 3% - 5%, and under Leaf Area Index of 0-2. We concluded that M. gilvus is primary decomposers and contribute to litter fragmentation and the recycling of nutrient into the soil. Macrotermes gilvus plays an important role as a source of heterogeneity in this ecosystem, particularly in under stresses condition. The density and dynamic of M. gilvus, be taken into account in the global strategy of the forest resources management and conservation.

Abstract
This studyaimed todescribe school cultures experienced by science teachers from three districts in Central Java, such as Kudus, Magelang and Brebes, from which some junior high schools are being promoted to be school models of scientific literacy, to explore symbolic nature of science teaching quality, and to identify possible barriers for its promotion. School culture was defined as science teacher’s perceptions of shared beliefs, values, and moral of the extend to which teachers experienced three constructs like professional collaborations, collegial communications, and self-determinations during their service to schools. Self-assessment with 17 items, from the 2015-2016 Georgia Leadership Institute for School Improvement Inc., was used with some modifications. 50 science teachers from these Districts completed the questionnaire.Observation was implemented to describe physical school environments. Open interviews were conducted to school principals, science teachers and students. Data analysis was focussed on the extend to which school culture components were strong, weak, and the meaning of symbolic nature. Findings showed(i) science teachers experienced good collegial relationships and self-determinations, but weak professional collaborations,(ii) science teaching quality was not contextual and lack of connectedness to socio-scientific issues and students’ creative portfolios, and (iii) school was lack of shared vision and mission that could be the most barrier for school improvement.
