    English is the most popular and most spoken language in the world which has been used effectively in many developing countries. One of the first skills that students should be learnt in English is listening. In learning language, students use listening to began the process of learning to comprehend and produce language. The problems that usually faced by students while listening are lack of control over the speed at which speakers speak, inability to concentrate (topic, effort, technical problems), and also established learning habit in listening perfectionism.This descriptive research was conducted in order to find out the students' ability in listening comprehension on descriptive text. The data were collected using test in the form of multiple choice. The test covered four components of listening comprehension question; finding main idea, finding detail, identifying inference, and identifying restatement.The sample of this research was the second semester students of English study program of FKIP-UR who had passed English Listening1 subject in first semester. They consisted of 3 classes: A, B, and C, and using cluster sampling technique, class B was chosen as the sample of this research. Before the data were collected, the try out was conducted in order to make sure that the test was good and valid. There were 7 rejected items and those items were revised before having been distributed to the sample. From the data analysis, it was found out that the students' ability in listening comprehension on descriptive text was in poor level with the average score 48.33. The result of the students' ability on listening comprehension of descriptive text was in poor level for finding main idea (44.81),identifying restatement (40.37), while finding detail was in good level (60.37), and for identifying inference was in average level (50.00).Based on the finding, it was suggested that the students need to improve their listening ability by practicing more on listening exercise and should motivate themselves to listen more listening materials. Other researchers can also focus on how to overcome the high level of difficulty of listening comprehension materials, particularly in listening to descriptive text

    A methodology of training pilots’ listening skills by means of a computer tool is highlighted in the article. Various computer exercises are used to enhance the learners’ level of English as well as improve their listening skills. English is one of the crucial factors influencing flight safety; pilot’s ability to listen, hear, interpret and react to controller’s information in English is of paramount importance during radio communication. It is emphasized that the development of computer software and appearance of new computerized tools predetermine the search for new methods of teaching Aviation English to future pilots and air traffic controllers. One of the ways how to enhance the level of professional training is implementation of ICT in the teaching and learning process. Computer technologies and technical means of language training can simulate the flight situations that a pilot may encounter during his/her professional activity. In the article the authors demonstrate one of the useful methods – application of a computer tool for training listening skills in Aviation English. The computer tool is aimed at training pilots’ listening skills. It can be used to prepare students for achieving ICAO Operational Level (Level 4) or higher according to the ICAO Language Proficiency Requirements. It consists of six tasks based on general aviation English and phraseology of radio communication. Based on the proposed methodology the experiment with Aviation graduate students was carried out, which was based on the implementation of the computer tool into the course «Phraseology of radio communication». Listening skills’ assessment was conducted according to three criteria: cognitive (knowledge), operational (skills), psychological (abilities) and their descriptors. According to the level of listening skills three levels – low, medium and high were differentiated. The results of the experimental study indicate that there have been positive changes in the distribution of students’ levels of listening skills in the phraseology of radio communication in English with the introduction of the computer tool: the number of students with high- and medium-level of listening skills increased whereas that of low-level listening skills decreased

    Arsenite [As(III)] and arsenate [As(V)] removal by direct contact membrane distillation (DCMD) using novel hydrophobic green, silica-based ceramic hollow fibre membranes derived from agricultural rice husk was investigated in this work. The green ceramic hollow fibre membranes were prepared from amorphous (ASHFM) and crystalline (CSHFM) silica-based rice husk ash and modified to be hydrophobic via immersion fluoroalkylsilane (FAS) grafting of 1H,1H,2H,2H-perfluorodecyltriethoxysilane. Superhydrophobic contact angle values up to 157° and 161° were obtained for ASHFM and CSHFM, respectively. Remarkably, the membrane surface morphology mimicked a look-alike lotus-leaf structure with decrement in pore size after grafting via the silane agent for both membranes. The effect of arsenic pH (3–11), arsenic concentration (1–1000 ppm) and feed temperature (50–80 °C) were studied and it was found that feed temperature had a significant effect on the permeate flux. The hydrophobic CSHFM, with a flux of 50.4 kg m−2 h−1 for As(III) and 51.3 kg m−2 h−1 for As(V), was found to be the best of the tested membranes. In fact, this membrane can reject arsenic to the maximum contaminant level (MCL) limit of 10 ppb under any conditions, and no swelling mechanism of the membranes was observed after testing for 4 hours

    The presence of water pollution which consists of heavy metals, fecal and others has produced a major problem. These can lead the water to the toxicity and the impurity of water will be disrupted. Therefore, it would not be safe to drinks and could be threatening to live health. In addition, the current market now is dealing with high-cost production to develop ceramic membranes and has been using expensive material to make the filtration system works. In order to challenge the issue, the preparation of ceramic water filtration at low-cost production and using an effectively silica from natural waste rice husk was evaluated. Rice husk was fired at 700ºC and 1000ºC respectively and produced rice husk ash which mutated to amorphous and crystalline silica. Five samples were fabricated after been mixed with the compositions of rice husk ash, kaolin clay, and wheat flour, used at 40:40:20 ratios by weight respectively. The fabrications of the ceramic membrane were conducted by using dry pressing. The samples then were dried in the oven at 60ᵒC for 1 hour followed by sintering at 1000ᵒC respectively. These samples (OO, C1, C2, N1, and N2) were tagged based on unwashed and washed material with the chemical. The properties of silica which are the microstructure and pore size, from rice husk ash were obtained by using Scanning Electron Microscopy (SEM), X-Ray Fluorescence (XRF) and x-ray diffractometer (XRD). Effect of silica content in ceramic filtration membrane was investigated and characterized in term of porosity, density, water absorption, membrane hardness, pore size, flow rate, the turbidity of water (before and after filtration) and pH value. From the result, sample C2 was the best option to support the objective by 98.60% silica content, 64.82% of porosity, 1.1433 mg/cm3 of density, 40.59% of water absorption, 171.0 Hv of hardness, 0.177 l/hr of flowrate and pH of 7.62 of water after filtration. In general, the quality of the ceramic filter membrane is reliant on the raw material, while the flow rate and water clarity are dependent on the pore size of the filter membrane
