Abstract

Marine oil spills have bad impacts on the marine biota. Oil spill mitigation that is currently safe, effi cient, relatively cheap and easy to implement is bioremediation, that is degradation of oil spills biologically using microorganisms. Petroleum will be more easily dispersed in water when surfactants are added. The surfactants have the ability to increase the bioavailability of petroleum to facilitate bacteria contact with carbon sources as their feed. This study was intended to test the effect of addition of diethanolamide (DEA) surfactants to improve the ability of bacteria to degrade hydrocarbon compound in the seawater media. The biodegradation experiment was conducted in 8-liter seawater media and the ability of DEA surfactants to reduce surface tension, oil content, pH and nutrients on days 0, 1, 3, 6 and 10 were observed. GC-MS analysis was conducted to detect chemical component changes in petroleum. A bacterial consortium of Enterobacter sp., Pseudomonas sp., and Raoultella sp. was utilized. The oil was degraded up to 65.52% with biodegradation rate k = -0.1054 t in the media added with DEA surfactants. The aliphatic fraction detected was C17-C31 n-alkane compound and after biodegradation it became C20- C31. The results showed that DEA surfactants were able to improve the ability of bacterial consortium to degrade petroleum.

Abstract

This research is aimed at improving the ability of oily wastewater biodegradation through the ozonation method, where ozone will oxidize organic compounds in the oily wastewater that are diffi cult to be degraded by bacteria so that the structure becomes simpler. The ozonation process is done by using a corona-discharge ozonator and semi-batch reactor, and the process is varied by ozone dose and pH value. The ozonation process is then followed by a biodegradation process, where the bacteria that is used is Pseudomonas sp. This study also observed the effect of surfactants in supporting the biodegradation processes. An indicator of research success is the increase in the biodegradation percentage of the sample, followed by an increase in the value of the constant rate of bacterial growth. The research results shows that the ozonation method and the use of surfactant can support the oily wastewater biodegradation process. This is shown by the value of the biodegradation percentage and the constant rate of bacterial growth results, in which respective values are able to reach 86,787% and 0,339 at the optimal operating conditions (ozone dose of 0.53 g/h; pH 7; Bios-H surfactant concentration 500 ppm).

Abstract

Contamination of petroleum waste has endangered the environment, yet its processing technology isnot effective and effi cient. It is becaused that by petroleum waste is diffi cult to be degraded by bacteria dueto many complex bonding compounds containned in this oil waste. Therefore, this study used ozonationas pretreatment process with the aim to enhance the biodegradation process. The variations in operatingconditions performed in this study are dose of ozone and pH. The bacteria used as a degrading agent isthe Pseudomonas aeruginosa. The results show thatozonation process can the enhancebiodegradabilityas indicated by the increase of degradation and population growths of bacteria. In addition, the abilityof the bacteria P. aeruginosa in degrading petroleum waste is varied with ozone doses and pH values.The highest percentage of degradation achieved at dose of 0.53 g ozone/h and pH 7.48 are approx from56.52% without ozone pretreatment to 79.32% after 7 days incubation.

Abstract

Oil sludge from petroleum industry effluent is classified as hazardous waste and requiredspecial treatment before discharge to the environment. Biodegradation using bacterialactivities is a general treatment for oil sludge processing. However, the bacterial abilityin oil sludge biodegradation is blocked by non-aqueous phase liquid of oil sludge. Twopossible ways of enhancing the bioavailability of oil sludge are surfactants application and slurry bioreactors system. The objective of this study is to obtain the surfactant which can increase oil sludge biodegradation using simple slurry bioreactor. The surfactant selection obtained Emulsogen LP (58% effectiveness) which was examined based on HLB value, nonionic character, and surfactant effectiveness. Emulsogen LP is readily biodegradable which reached 93% biodegradability in 15 days. The biodegradation test showed that Emulsogen LP addition on its Critical Micelle Concentration (10 mg/L) enhanced oil sludge biodegradation in 3 bacterial cultures of Pseudomonas aeruginosa, Bacillus subtilis, and Actinobacter baumanni after 48 hours. By surfactant addition, oil sludge biodegradation reached 37-49% whereas without surfactant addition it only reached 28-33%. The highest oil sludge biodegradation was obtained in P. aeruginosa cultures with Emulsogen LP addition (49%). The surfactant addition had no effect on microbial growth. Moreover, P. aeruginosa population was increased by surfactant addition.

Abstract

The aim of this study was to determine whether the students participating in the English Debating Club have better English-speaking skills after using the OME TV application. Randomized Controlled Trial (RCT) was conducted by dividing sample into two groups of an experimental and a control groups. A pre-test and post-test were administered to both groups; however, the OME TV program was only used to treat the experimental group. There were 30 students chosen as the sample from the population, which included 50 members of the English Debating Club. The data was analyzed using t-test after the confirmation of the normality and homogeneity data fulfilment. The findings show that there is a significant difference between the experiment and control groups with a significance value (Sig. 2-tailed) of 0.013 < 0.05. Accordingly, the OME TV application significantly raised students' speaking proficiency. This suggests that incorporating interactive digital media can improve language learning results.

Abstract

Vocabulary as one of English component and it’s very important to learn. Before the students master the four skills they have to know some vocabularies to support them in learning English. English vocabulary as one of the language skill elements has an important role for young learners in learning foreign languages. In presenting English, especially vocabulary, the teacher should be creative in choosing materials and able to stimulate the student's interest. The teacher needs to manipulate some strategies to support the teaching and learning process. Teaching English for young learner is different from teaching adults in a way that they are often more enthusiastic, active and easily adaptive than adults. The type of this research is descriptive qualitative research. This research is a descriptive qualitative research that focuses on vocabulary building strategy in teaching vocabulary to young learners. It describes the technique and method used by the teacher in teaching English vocabulary to young learner.

Abstract

Abstrak: Penelitian ini berfokus pada evaluasi efek ekstrak air daun Kirinyu (Chromolaena odorata) terhadap ekspresi Fibroblast Growth Factor-2 (FGF-2) selama fase 2 penyembuhan luka pada tikus (Mus musculus), menyoroti pentingnya senyawa alami dalam perawatan medis. Pendekatan eksperimental laboratorium menggunakan Desain Acak Lengkap diterapkan pada 28 tikus, yang dibagi menjadi empat kelompok, masing-masing menerima konsentrasi ekstrak air daun Kirinyu yang berbeda. Penilaian ekspresi FGF-2 dilakukan melalui analisis imunohistokimia. Penelitian ini menemukan bahwa ada efek ekstrak air daun kirinyu terhadap ekspresi FGF-2 pada akhir fase 2 penyembuhan luka pada tikus, sebagaimana dibuktikan oleh intensitas, persentase dan ekspresi FGF-2 yang signifikan. Dalam penelitian ini, konsentrasi 5% ekstrak air daun kirinyu (Chormolaena odorata) merupakan konsentrasi yang paling efektif dalam ekspresi FGF-2 pada akhir fase 2 penyembuhan luka pada tikus (Mus musculus). Peningkatan ekspresi FGF-2 menunjukkan potensi ekstrak air daun Kirinyu sebagai agen alami yang efektif untuk meningkatkan penyembuhan luka. Efek ini mungkin disebabkan oleh senyawa bioaktif yang ada dalam ekstrak, yang dapat meningkatkan aktivitas fibroblas dan proses penyembuhan lainnya. Ekstrak air daun Kirinyu menunjukkan potensi sebagai pilihan terapi alami untuk penyembuhan luka, menawarkan jalan yang menjanjikan untuk pengembangan pengobatan baru berdasarkan pengobatan tradisional.
