Abstract

During crude oil and natural gas extraction from a reservoir, a large amount of water is also produced. The water fraction contains oil, grease, organic and inorganic constituents, called produced water (PW). Over the years, efficient treatment of PW has been concerned. PW has been treated with various technologies, namely floatation, filtration, coagulation/flocculation, or biological processes. Those technologies were assembled to achieve discharge standards while minimizing the cost. Exploration of membrane-based technologies for the treatment of PW has recently been reported, including the emerging forward osmosis (FO) process. This paper reviews the research progress on the FO process for PW treatment. A brief introduction to the traditional treatment technologies is first provided. Next, the basics of the FO process and research progress on the application of FO on PW treatment are discussed. Finally, techniques for fouling control in FO are reviewed, namely osmotic backwashing, ultrasound, chemical cleaning, and air sparging.

Abstract

Peningkatan publikasi ilmiah Indonesia pada jurnal ilmiah mengalami peningkatan pesat. Pada tahun 2019-2020, Indonesia bahkan berada pada peringkat 1 di ASEAN. Sayangnya peningkatan jumlah publikasi tersebut tidak dibarengi dengan peningkatan jumlah sitasi sehingga menunjukkan minimnya kualitas tulisan ilmiah Indonesia. Permasalahan tersebut dapat disebabkan oleh kurangnya kemampuan dalam menulis karya tulis ilmiah. Artikel ini bertujuan untuk menguraikan standar isi pada tiap komponen artikel ilmiah seperti abstrak, pendahuluan, metode, hasil dan pembahasan, dan kesimpulan/implikasi. Tiap komponen tersebut setidaknya berisi 200-250 kata yang terdiri dari 18 paragraf sehingga total jumlah kata pada satu artikel ilmiah adalah 3600-4500 kata. Detail isi pada setiap paragraph dijelaskan lebihlanjut pada artikel ini. Standard Content of Research Paper: Detail Component to Get Publish in Scientific Journal Abstract The increase of Indonesian scientific publications in scientific journals has increased rapidly. In 2019-2020, Indonesia is even ranked 1st in ASEAN. Unfortunately, the increase in the number of publications was not accompanied by an increase in the number of citations, thus indicating the low quality of Indonesian scientific writings.

Abstract

Combustion of corn leaf as a model of biomass from agricultural waste is a simple way to obtain the energy. It produces a low-value by-product of ash and is rich in silica that can become a precursor for zeolite production. In this study, acid-treated corn leaves combustion was performed to produce high purity silica (SiO2). The diffraction pattern suggested that the extracted silica was amorphous without the impurities phase. Additionally, the nitrogen isotherm indicated that the material was highly mesoporous silica with a total surface area of 200 m2/g. The hydrothermal method was then applied with a composition molar ratio of 1.25SiO2:1Al2O3:5Na2O:250H2O to synthesize zeolites from the silica. The temperature and time effect on the hydrothermal zeolite’s synthesis was investigated. The diffraction pattern shows that high crystalline zeolite Na A-X was produced at temperatures of 100°C and 8 h hydrothermal time. According to nitrogen physisorption analysis, the zeolite Na A-X consisted of micropores with a total surface area of 270 m2/g. The morphology of zeolite Na A-X was cube for the Na-A and octahedral for the Na-X. The hydrothermal temperature and time highly affected the zeolite formed. This research suggested that the ash waste could be valorized through conversion into a high economic value zeolites.

Abstract

Numerous agricultural wastes are well-defined as low-cost sources and rich in silica content. The residue of oil palm wastes combustion seems a promising silica source and can be recovered through a straightforward method. In this study, the combustion followed by an alkaline extraction method was employed to extract high purity of silica. The oven-dried oil palm decanter cake (DOPDC) was heated at combustion temperatures of 600, 700, 800, and 900°C to produce OPDC ashes (OPDCA), followed by an alkaline extraction using 5M of NaOH solution. Thermogravimetric analysis (TGA) was used to observe the thermal behavior of DOPDC where the suitable combustion temperatures to produce silica ranged between 600 and 1000 ℃. X-Ray Fluorescence (XRF) analysis showed that silica contents were 31-36% after combustion, increasing to 76.95% after the chemical treatment. Moreover, the spherical shape of the silica was observed through electron microscope analysis. It was represented by the aggregation of silica after going through chemical treatment. The X-Ray Diffraction analysis also proved that the amorphous silica was produced, characterized by the hump-shaped spectrum. The infrared analysis confirmed that the silica had been successfully extracted from OPDCA by the presence of silica functional groups shown in the spectrum.

Abstract

This paper discussed the removal and the remediation of emerging contaminants (ECs) in water using adsorption and membrane filtration as a single and hybrid system. The classifications, sources, effects, detection techniques, and available technologies for ECs removal were discussed. Next, an overview of both adsorption and membrane filtration processes in terms of materials, separation mechanisms, factors affecting their performances, and their applications for ECs removals was provided. It was followed by a comprehensive review of the combination of the membrane and the adsorption processes with other physical, chemical, or biological treatments. Finally, progress in research on a hybrid system between membrane filtration and adsorption was discussed. The combination included adsorption as the pre-treatment, integrated adsorption/membrane filtration system, or adsorption as the post-treatment. Generally, the hybrid systems showed improved performance than a single system. Nonetheless, further studies are recommended for applications of those systems on a wide range of ECs removals and the scale-up issue.

Abstract

Alignment of inquiry learning has embarked on remote inquiry as a replacement for face-to-face inquiry. On the other hand, the current technological developments bring opportunities to use it as a learning resource to support critical thinking. The current study explores the impact of virtual simulation-assisted remote inquiry in Fourier transform courses on prospective STEM teachers' (PST) critical thinking (CT) skills. The experimental design employed a randomized pretest-posttest control group was employed. Two groups of samples were randomized: the experimental group, n = 30, and the control group, n = 30. The treatment of learning was different in each group. The experimental group was conducted by virtual simulation-assisted remote inquiry, while the control group was conducted by online learning without inquiry and simulation. The measured CT skills aspects included analytical, inference, evaluation, and decision-making measured by an essay test instrument. The results were then analyzed descriptively and statistically. The results confirm that the virtual simulation-assisted remote inquiry significantly improved PST CT in Fourier transform courses. The virtual simulation-assisted remote inquiry learning was better than courses with online learning without inquiry and simulation. The virtual simulation-assisted remote inquiry provided conceptual formation and application of concepts. It strengthened the opportunities for the PSTs to train their CT skills.

Abstract

This study evaluates implementation of asynchronous learning in teaching engineering electromagnetics module. A group of first-year engineering students participated in the study. The instruction was divided into two periods, with the first period using asynchronous online mode and the second period using synchronous face-to-face mode. The performance evaluation was based on essay questions on class tests, and the data variances were statistically analysed. In addition, student feedback was gathered through interviews conducted at the end of the semester. In terms of overall performance, the results indicate that synchronous and asynchronous learning methods were equally effective, as no significant difference was found. However, individual student grades revealed a variety of outcomes for the asynchronous learning method, suggesting that students have different learning preferences and levels of adaptability. Positive feedback for asynchronous learning included the ability to adjust the pace of learning and conveniently access course materials. Students valued the availability of recorded lectures for reviewing difficult subject matter. Students with lower study motivation or limited experience with independent learning were negatively affected by the absence of scaffolding and immediate feedback in the asynchronous learning approach. Some students emphasized the importance of face-to-face interaction with the instructor, especially in a subject like electromagnetics that requires intuitive thought and elaboration.

Abstract

Wetland water is opted as the source of domestic water supply when the availability of clean fresh water is scarce. Wetland water requires proper treatment due to the high concentration of organic matter and high salinity, particularly in the dry season. This research aims to synthesize, characterize, and investigate the performance of polyvinylidene fluoride (PVDF)-TiO2 hollow fiber membrane for wetland saline water desalination via pervaporation. The PVDF-TiO2 hollow fiber membranes were fabricated through the dry wet spinning method under various air gaps (10, 15, and 20 cm). Then, the resulting membranes were tested in a pervaporation process at temperatures of 25, 40, and 60°C. Results show that the incorporation of TiO2 into the PVDF matrix imparted hydrophilicity properties into the resultant membranes. The presence of TiO2 was confirmed by the TiO2 stretching vibration at 1640 cm-1 (FTIR) and the TiO2 phase at diffraction peaks at 25.5 and 37°. The membranes exhibited the highest water flux (7.48 kg/m2.h) and salt rejection ( 99.5%) at 40°C. Overall, the developed PVDF-TiO2 hollow fiber membranes showed encouraging results and demonstrated their effectiveness for the desalination of wetland saline water.
