Abstract

Phenol is an organic compound that is toxic to humans and the environment. This compound was contained in the hospital liquid waste and petrochemical-based industrial sectors. This study aims to obtain hydrocarbonoclastic bacterial isolates that act as biodegradation agent in waste handling. Samples obtained from the biofilter tank of liquid waste treatment Bhayangkara Hospital Denpasar,Bali, Indonesia then carried out isolation and inoculation of bacteria in selective media NA (Nutrient Agar) containing Phenol. The bacteria obtained was performed the viability test on the media with various Phenol concentration levels, obtained three isolates of bacteria capable of growing to the concentration Phenol 500 mg / L, i.e. isolates IB2, IB5, and IB10. Therefore, it was performed the degradation ability and rate test on those three isolates. After 72 hours of incubation periods, the change of Phenol concentrations was analyzed using the folinciocalteau method and examined using the spectrophotometer with 660 nm of wavelength. Based on the analysis of final phenol content, the IB2 isolate has the highest degradation capability in the concentration of 600 mg/L (153,4 mg) with a degradation rate of 2,13 mg/h. IB5 isolates have the highest degradation capability in the concentrations of 700 mg/L (109,45 mg) with a degradation rate of 1,52 mg/h. Meanwhile, IB10 isolates show the lowest ability and degradation rate in both concentrations. Through morphological identification and Gram stain, three isolates belong to the Gram-negative rod-shaped bacteria, which has similarities with the Pseudomonas genus.

Abstract

Tourism is growing very rapidly with the development of technology, especially information technology .Through information technology people can easily get access to information about various destinations and tourist attractions as well as hotel by online media communication. Therefore, this study was trying to use social media such as facebook and twitter, where both social media were widely used by companies engaged in tourism in the world as well as in Bali. Internet consists of several websites, but the most effective one to conduct the research on tourism such as webseries 2.0 or commonly called as social networking media. Social medias - Facebook and Twitter - both were wildly used by the companies running in the sector of tourism in Bali, such as Hotels, Villas, Restaurants, Spas, Travel Agents, Airlines, and Tourist Attraction Managements, to advertised their products and services in their respective field. Through those social media, tourists will be able to access the comments or reviews about the companies. The problem raised in this research is how Bali’s tourism data in social networking media were used and considered, and how was the image of Bali’s tourism in their point of viewbased on the research. The method used here was descriptive qualitative method which describes this phenomenon descriptively by analyzing the obtained comments on social networking media such as facebook and twitter, and then classified in the form of comments positive, negative, and unidentified comment. Afterwards comments were re-analyzed through 4A Approach which consist of Attraction, amenities, Ancillary, and Accessibility. Data which has been obtained re-analyzed via the data obtained from the homepage of (TripAdvisor and Agoda.com). In addition, to strengthen the research data obtained from the homepage of TripAdvisor and Agoda.com , then it has been elaborated on the point rating system which indicatedthat the company were registered in both of those social networking media such as Hotel, Villa, SPA, restaurants, travel agents, airlines, media, tourist attraction management has a good rating result, and it has represented that the image of Bali tourism has a good rank in the eyes of local and international tourists. This data was also strengthened by the existence of empirical studies where there were the data from a hundred tourists came to Bali both locally and internationally has filled out the questionnaire about Bali in order to obtain maximum results on the image of Bali tourism. The results showed that, social networking media were effectively used in this study. Many companies in Bali used facebook and twitter. In addition, Bali Tourism image placed in positive rank on both of social networking sites, and it was gained by the results of questionnaires spread towards the visitor.

Abstract

Diesel fuel is widely used in manufacturing and transportation industries. Its production, transportation, use and disposal have the risk to contaminate the environment. In the other hand contaminated site usually can produce some microorganisms, through natural selection, that can utilize the hydrocarbons as source of energy and food thus clean the environment itself. For bioremediation purposes, 14 isolates of diesel oil degrading bacteria from Bandung, Jakarta, and Bali has been employed for diesel oil degradation. These 14 isolates, together with other variables, e.g. pH, Pb, sucrose and urea, were plotted in 23x24 matrixes of Plackett and Burman statistical method. Fermentation was carried out in batch cultures for 14 days. The results showed that 9 isolates and the availability of sucrose and higher initial pH have a positive/stimulatory effect on diesel oil biodegradation, 5 of which were very significant (99.99%), whereas 1 isolate has inhibitory effect (-98%). The results also revealed that 8 isolates, higher initial pH, and availability of urea have stimulatory effect on culture growth (more than 90% significant). The present of Pb in medium inhibit both growth and the degradation of diesel oil, although the effect was not significant (less than 60%).

Abstract

Antifungal Activity of Gracilaria sp. against Pathogenic Fungi Fusarium solani (Mart) Sacc. Cayenne pepper The use of chemical pesticides as a control for cayenne pepper fusarium wilt caused by the Fusarium solani continuously for a long time can have a negative impact on the ecosystem, and toxic for humans. Seaweed Gracilaria sp. as a marine commodity that is abundant in Indonesia, especially in the Bali region, it contains bioactive compounds that have the potential to be developed as an antifungal. This study was aimed to determine the effectiveness of Gracilaria sp. in inhibiting the growth of Fusarium solani (Mart) Sacc. This research was a single factor experiment which was compiled based on a completely randomized design (CRD) consisting of six treatments of the concentration of Gracilaria sp. and each treatment was repeated 3 times. The treatment was given various concentrations of Gracilaria sp. in the fungus F. solani, the concentration is 0%; 0.5%; 1%; 1.5%; 2%; and 2.5%. Treatment was positive control (ketoconazole) and negative control (Tween 80). The results of this study indicate that the extract of Gracilaria sp. has antifungal activity that is fungistatic with weak inhibition against the fungus F. solani. MIC test results show that the minimum extract that can inhibit the growth of Fusarium solani is a concentration of 0.5%. MIC test results show that the minimum extract that can inhibit the growth of F. solani is concentration of 0.5% with an average diameter of 4 mm with a weak category. The highest inhibition power of Gracilaria sp. to F. solani in this study was 2.5% with inhibition of colony growth of 79.3%. The percentage of spore growth inhibition was 67.49%. The concentrations studied showed that the higher the extract concentration, the greater the inhibition power of Gracilaria sp. against F. solani.

Abstract

Isolation and Identification of Cellulolytic Bacteria in Organic Waste at TPA Suwung Denpasar Organic waste contains a lot of lignocellulosic material which can be degraded by cellulases. The degradation of cellulose requires three types of enzymes produced by microorganisms. Cellulolytic bacteria are one of the microorganisms involved in the decomposition process and produce cellulase enzymes which can degrade organic matter. This study aims to isolate and test the ability of cellulolytic bacteria in the organic waste of TPA Suwung Denpasar by isolating morphological identification, and quantitative cellulase test. The results of this study found twenty-seven (27) bacterial isolates that were able to grow on CMC media and were classified based on colony morphology and obtained 3 different isolate groups. The isolates that had been grouped were coded A, B, and C. The colony of the isolated isolates appeared to be round and wrinkled. Some surfaces are convex, raised, and hilly and are clear, yellows in color, and white. Isolates A and C were gram positive, while isolate B was gram negative. Based on the calculation results of the Cellulolytic Index value, it was found that isolate B had the highest IS and was in the high category.
