Examining the Role of Gender and Educational Level in Committing Plagiarism by Iranian EFL Graduate Students
Authors: Alimorad Zahra
Published: June 2020

As an unethical behavior, plagiarism refers to using other people’s words or ideas without appropriately acknowledging the source (Delvin & Gray, 2007). Numerous scholars from different parts of the world have attempted to get into the root of this problem by identifying the underlying factors which contribute to such academic misconduct. In a similar vein, the present study aimed at examining the role of gender and educational level of Iranian EFL graduate students in determining the main reasons for plagiarism commitment from their point of view. To this end, a convenient sample of 159 M.A. and Ph.D. students partook in the study. To gather the necessary data, a 32-item Likert-Type questionnaire was administered whose results were subjected to a two-way MANOVA. Results of the study indicated that neither the students’ gender or educational level nor the interaction effect of these two variables had any significant effect on the reasons for engaging in plagiarism. Descriptive statistics, however, showed that students’ personal and attitudinal characteristics took on paramount importance compared to other factors. This can signal the intentionality of plagiarism among Iranian EFL graduate students, thereby suggesting the need for making more informed decisions on how to deal with this problem.

DENITRIFIKASI LIMBAH NITRAT PADA BERBAGAI TINGKAT KEASAMAN DENGAN MEMANFAATKAN MIKROBA AUTOTROPH
Authors: Nugroho Rudi
Published: June 2020

A biological denitrification using autotrophic bacteria in batch suspension runs was investigated to clarify the effect of pH on denitrification rate. Elemental sulfur was employed as an electron donor. The culture of autotrophic bacteria was obtained from activated sludge by acclimatization. The effect of pH on denitrification rate could be expressed by bell-shape equation with optimum pH of 7,07. However at a pH range of 5,5 to 8,0, the denitrification rate significantly fastl. Therefore, the application of the denitrification of wastewater using autotrophic bacteria is suggested running well although without controlling pH.  Kata kunci : Denitrification, nitrate, autotrophic bacteria, elemental sulfur, pH.

Crude palm oil produced in Indonesia has already been known as the second largest in Asia. Unfortunately tens of palm oil factories (CPOF) spread out in Indonesia have not good wastewater treatment plants (WWTP) yet. PT. Kertajaya, as an example, which is located in Regency Pandeglang, still has BOD contained in its final effluent of the wastewater treatment plant more than 200 ppm. In fact the capacity and capability of WWTP in PT. Kertajaya are much more than enough for only 288 m3 per day. Because of improper operation and maintenance of the WWTP, the technical problems are accumulated, such as, increasing the sediment, decreasing the retention time and channelling of the wastewater being treated. The following affect is the treatment process is not going well and the quality of effluent is getting worse. To solve the technical problems, it is very important to remove the sediment periodically and give aeration in the aerobic pond. A recommendation for the wastewater treatment system has been proposed. The system has eight processes including oil separation or first sedimentation, neutralization, equalization, anaerobic degradation, aerobic degradation,  final sedimentation and sludge drying. Katakunci : BOD, technical problem, wastewater, anaerobic.

In line with fast growth of populations in urban area the discharged waste water from daily activities have caused contamination of ground water and also surface water. Unbalance between distribution of source and usage of water have caused unbalance between supply and demand. Therefore, new innovation in the case supply of raw water has come to important attention. One of the alternatives which getting much attention in many state in world is to use recycle wastewater especially municipal wastewater as one source of raw water for water supplySeveral things which need to be paid attention in the case of usage of recycle wastewater are consistency of the treated water quality as according to enabled condition. In usage of recycle wastewater to be used as clean water supply there is several categorize of contaminant which must be paid attention peculiarly namely for example organic contaminant including pesticide, pathogenic bacteria, parasite, virus and also heavy metal contaminant for example mercury, lead, chrome, cadmium etc. Therefore the treatment process must be done neglectlessly with control of quality which able to be justified.One of the concept for processing of urban wastewater to be made clean water is use combination of primary treatment, secondary treatment with biological process continued by advanced treatment by physico-chemical process for example covering clarification process, nutrient removal, recarbonation, filtration, adsorption with activated carbon, ion exchange process, and also demineralization with process of reverse osmosis and also ozonization and chlorination. With these processes combination can treat wastewater yield treated water with quality of as drinking water.This paper explained some example of wastewater treatment process for recycle wastewater which have been applicated in some state. One of the example of wastewater recycle process using combination of biological process continued with ultra filtration process, reverse osmosis process, and disinfection by ultraviolet, and also pH control such as those which have been conducted by NEWATER Factory, Singapore. Kata Kunci : Daur ulang, air limbah, teknologi, lingkungan.

Authors: Nugroho Rudi
Published: June 2020

Effect of nitrite on denitrification of synthetic wastewater using autotrophic bacteria was evaluated in both batch suspension and continuous packed column runs. Emphasis was placed to clarify the minimum concentrations of nitrite and nitrous acid that inhibit the denitrification rates. Batch suspension runs were conducted by mixing acclimatized denitrification sludge and synthetic wastewater in an Erlenmeyer flask. In continuous runs, denitrification sludge was loaded to a column packed with sulfur and limestone. The nitrite inhibition could be explained satisfactorily by substrate non-competitive inhibition model. The minimum concentration of nitrite which inhibits the nitrate and nitrite removal rate lowered with decreasing pH. In suspension runs, the minimum concentration of nitrous acid which inhibited the nitrite removal rate was 0.043 g-N/m3, while the nitrate removal rates was inhibited below 0.012 g-N/m3.  Both in suspension and continuous packed column runs, nitrate removal was more sensitive against nitrite increase compared with nitrite removal. The minimum concentration of nitrite which inhibited nitrate removal rate in continuous packed column runs was lower than that in suspension runs.  Keywords:Autotrophic bacteria, denitrification, inhibition, nitrite, sulfur

Contamination of rivers has reached an alarming level, especially in the rivers passing through major cities, agricultural areas and industrial areas. Among the contaminants that often appear dominant and very disturbing is the organic substance. The existence of high organic matter within the river water is often expressed in permanganate number that has passed the quality standard. River that contain high organic matter usually the water smell and the color is black, besides it can also cause disturbances in the water treatment process, which is an increasing use of coagulants, chlorine, activated carbon, and the emergence of substances that are not desired, and the quality of treatment results are unsatisfactory. Many ways to reduce the organic matter in river water, one of them is by using the biofilter honeycomb structure. The target of the reduction of organic substances is that the river water could be used as a raw drinking water quality standards or meet the category B, Regulation of Jakarta Governor Number 582, 1995. Raw water used for this study were taken from Krukut River which is the raw water for Regional Water Company PALYJA, Production Installation III Cilandak, South Jakarta and Cengkareng Drain river water, which is currently used as a source of raw water for PAM Taman Kota, West Jakarta using a biofilter reactor aerobic system, the capacity of 50 - 200 m3, Capasity of Blowers 300 l /min, Residence Time 6 hours up to 1 hour.

Published: June 2020

The predicted changes in precipitation patterns because of global change have profound effects on terrestrial ecosystems. In the present study, the principle and design details of a rainfall enrichment system (RAINES) for open field experiments in semi-arid and arid ecosystems are shown. The rainfall intensity, validity and uniformity of this experimental facility were also tested. During the period from 2008 to 2010, our data showed that the RAINES was able to simulate rainfall events with different rainfall sizes, frequencies and timing. The greatest advantage of the RAINES was its high uniformity in rainfall distribution over a relatively large experimental surface area (>90 m2), which was important for experimental studies of semi-arid and arid ecosystems where vegetation distribution is sparse. The rainfall validity of RAINES was steadily at 66% or higher as long as the hydraulic pressure exceeded 1.4 KPa and the wind speed was below 2.5 m s-1. Since the RAINES is light-weight, inexpensive and versatile enough to be used to simulate various rainfall events with needed properties in remote fields, it is able to provide reliable simulated rainfall in the field for studying possible responses of soil and vegetation processes to rainfall change in arid and semi-arid ecosystems. The application of the RAINES will improve our understanding on the relationship between water availability and ecosystem processes in arid and semi-arid ecosystems, which will provide useful knowledge for the protection, restoration and sustainable management of semi-arid and arid desert ecosystems world.

Objectives: To correlate the incidence of pressure injury (PI) with the average time of nursing care in an intensive care unit (ICU). Method: Epidemiological, observational, retrospective study, carried out in the ICU of a university hospital. Data were collected by consulting the PI incidence and the average nursing care time from ICU databases between 2010 and 2014. Measures of central tendency and variability, and Pearson’s correlation coefficient were used for data analysis. Results: The average incidence of PI between 2010 and 2014 was 10.83% (SD = 2.87) and the average time spent in nursing care for patients admitted to the ICU was 15 hours (SD = 0.94). There was no statistically significant correlation between the incidence of PI and the nursing care time (r = -0.17; p = 0.199), however, the results suggested an overload on the nursing team. Conclusion: This study confirms the importance of implementing and reassessing the effectiveness of preventive care protocols for PI, in addition to warning about the work overload of nursing in assisting critically ill patients.
