Abstract:
Traditionally, teaching and learning processes have always taken place in classroom environment that promote effective teaching and learning be it using the contact or virtual platform, however, the Corona Virus Disease -19 called COVID-19 has disrupted these educational processes. Overall, in research the impact of COVID-19 on the education system has gained critical importance, with the hope of drawing scientific driven solution to this predicament. Subsequently, in attempt to contribute some insights on dilemma facing teaching and learning in schools during COVID -19, this study is premised on the belief that, although effect of the pandemic is broad a unit level analysis of the educational processes and context specific driven approach should be adopted towards understanding the impacts of the pandemic. As a result, this study thus investigated the impact of COVID-19 in accounting classrooms in selected South African high schools in rural based contexts of Amatole. A qualitative approach in particular a case study research design was employed. The findings revealed that, preparation of accounting learners was negatively affected especially those who were in the exit level, as a result these learners are likely to struggle to cope with accounting studies in their first year at university or college due to challenges of COVID-19. Findings further revealed that both teachers and learners were not given any form of support during the lock down due to COVID-19 pandemic. There researchers recommend that counseling workshop is for learners should be conducted to alleviate the pressure associated with COVID-19 pandemic.

Abstract:
This study examines students’ perceptions of factors influencing the adoption and use of Information and Communication Technology (ICT) in learning during Coronavirus Disease (COVID-19) at one rural based South African University. To continue with learning under the COVID-19 pandemic conditions higher education institutions migrated to online teaching and learning platforms. The transition towards online learning took place in background where even prior COVID 19 most institutions were faced with the challenge of promoting students’ adoption and use of ICT in their learning. The Technology Acceptability Model (TAM) is an information system theory that looks at various individual aspects that influence actual technology usage and acceptance. As such, there is a growing research interest to explore students’ perceptions of factors that influence their use of ICT in their learning at higher education institutions subsequently studies that focuses on rural based context are still limited. Resultantly, guided by the theoretical constructs from the TAM this study applied a census approach and used a quantitative technique to examine the perception that affect students’ acceptance and use of ICT in their learning. The study discovered a significant correlation between attitude towards use (U), perceived ease of use (PEOU), behavioural intention (BI), and perceived usefulness (PU), all of which have a substantial impact on students' perceptions and acceptance of ICT use in their learning. Nonetheless, the results showed that no significant correlations exist between external variables (EV) and ICT actual system uses. Based on these findings, this study concluded that insights from the findings on students’ the adoption and use of ICT in learning is affected by several perceptions, behavioural intention, and perceived ease of use of technology. Such insights provide policy makers with an indication of students’ perceptions that should be considered when designing strategies an polices aimed at enhancing student’s adoption and use of technology in learning in rural based South Africa University during and post COVID-19 pandemic.

Abstract:
The main objective of this study was to map (1) the research of metacognition in science learning; (2) learning interventions used and metacognition’s key components that learned, integrated, and investigated; and (3) future research recommendations of metacognition research in science learning. We analyzed 438 scientific documents published in journals and books indexed in the Scopus database using VOSviewer software to visualize research trends and main keywords investigated of metacognition in science learning. The research findings show that research in the field of metacognition in science learning through the metacognition as attribution that integrated into learning interventions and as a learning outcome has increased in the last two decades. Scientific concepts understanding, critical thinking skills, motivation, and attention are the main goals in metacognition research. Inquiry-based learning, such as problem-based learning, is the most frequently used intervention to teach students metacognition. The research gaps found are (1) the cognitive regulations are the most investigated aspect, while cognitive aspects such as declarative knowledge, procedural knowledge, and conditional knowledge have not been widely investigated in science learning; (2) metacognition research on college students has a high frequency compared to school students; and (3) the integration of metacognition in online learning is still less investigated, this is indicated by the recommendations of several research results that encourage the integration of self-regulated learning into online learning.

Abstract:
Countless research has been published on the impact of covid-19 on improvements in teaching techniques, activities, and motivational beliefs. Most research refers to a human's response before learning without testing students' comprehension and literacy linked to covid-19. This study adopted a qualitative approach, with a questionnaire serving as the primary research tool. Alternatively, the current study looks into students' cognitive and portrays their mental model of COVID-19. At the Islamic University of Lamongan, 30 students from the science education department and 30 students from the environmental health department took part. Students are chosen as transformational leaders and liaisons between society's academic and social environments. The researchers gather data based on an open-ended assessment that evaluates the concepts, causation, methods, and strategies that must be implemented to prevent the transmission of COVID-19. Participants completed questionnaires prepared for educational purposes before and after learning. Inductive and iterative investigation of the descriptions of students' answers revealed cognitive outcomes and mental models. Each questionnaire form is then checked for validity using the SPSS v24 program. The authenticity of the questionnaire responses for each questionnaire > rcount (N = 60), indicating that each question is valid, whereas the reliability test using Cronbach's Alpha provides a score of 0.78 > 0.60, indicating that the questionnaire employed is trustworthy. Regarding educational, cognitive processes, the analysis shows that some colleagues believe that COVID-19 is a conspiracy, while others need to add sufficient scientific literacy to validate that COVID-19 is a disease. Even after learning, they can only make general ways to mitigate the propagation of COVID-19. The findings for student mental models revealed considerable changes in clarity and coherence, such as models at levels 1 through 5 with the highest student mental models. This study culminates with the implication that students require scientific literacy to effectively communicate about COVID-19 and check out false information in public.

Abstract:
Accounting education is crucial because it establishes the core knowledge required for education and growth in any country. During COVID-19, teachers in Accounting schools, like those in other educational institutions, were expected to adopt virtual classroom to continue their educational activities. This study aimed to demonstrate the virtual classroom readiness of Accounting school teachers in South Africa during the Covid-19 pandemic. The study employed qualitative research methods in this study, and the case study research design was used to explore the reality about virtual classroom readiness of Accounting school teachers and semi-structured interviews and thematic content analysis were employed to generate data. Results show that teachers are not prepared to implement virtual classroom during the Covid-19, according to the findings, and no one is assisting them. Another result indicated that virtual classroom facilities are lacking in schools. Education officials should offer ongoing virtual classroom courses for teachers, according to the study. In this study author concludes that, in order for instructors to be prepared for virtual classroom, educational administrators must oversee its implementation. In this study the author recommends that teachers must notify people in charge of education about what needs to be done in order to provide high-quality instruction.

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:
The current study describes how the guided-discovery-learning model impacts students' conceptual understanding (SCU) and students’ critical thinking skills (SCTS) on the topic of solubility. The quasi-experimental research with a posttest-only nonequivalent control group design was used in this study. The experimental group (45 students) and the control group (47 students) were selected by the saturated sampling technique. Data on SCU was collected using an objective true false test instrument with correction/proofing, while data on critical thinking skills was collected using an essay test instrument. The research data were analyzed descriptively and statistically (Mann-Whitney U). The research found the SCU (mean= 81.51 vs. mean= 72.81) and SCTS (mean= 70.46 vs. mean= 58.43) in the experimental group was better than the control group, both descriptively and statistically (p < 0.05). These findings indicate that the guided-discovery-learning model significantly impacted SCU and SCTS on the solubility topic.

Abstract:
This paper reports ZnPt bimetallic nanoparticles (ZnPtBNs) synthesis through the liquid phase deposition (LPD) of of Zn(NO3)2.6H2O onto the indium-titanium oxide (ITO) substrates at various concentrations. The Effects of growth solution, the morphology, structural, and sheet resistance were studied. After preparation, the materials were characterized by using field emission electron microscopy (FESEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and Four Point Probe (FPP) measurement by using Keithley 2401 source-meter. By inserting a growth solution into the ITO substrate the ZnPtBNs was successfully in-situ prepared. The synthesized ZnPtBNs exhibited homogeneous, fibrous at the (111) orientation with an average diameter of 100-700 nm. The atomic ratio of Zn:Pt and sheet resistance of ZnPtBNs decreased with the increase of Zn(NO3)2.6H2O concentration. The optimal elemental composition of the sample was at a ratio of Zn:Pt (1:25) obtained at 0.467 mM of Zn(NO3)2.6H2O. It showed the smallest sheet resistance (13.41 ?) which was 38% lower than the ITO sheet resistance (18.44 ?).

Abstract:
This study aimed at analyzing the correlation between reading and listening in TOEFL ITP test and how much reading predicts listening. It involved 50,684 reading and listening scores in 2015-2019 test periods of undergraduate students in one of the state universities in Malang. The data were collected by using standardized TOEFL ITP issued by ETS. Using Pearson Correlation Product Moment and linear regression analysis, the result demonstrated reading and listening had significant, linear, and strong correlation (.682), and reading significantly predicted 46.5% variance of listening. The results lead to the hypothesis that two language input skills, reading and listening significantly correlated and predicted one another. The result also suggested that correlation language skills not only occurred among reading and writing and listening and speaking, but also it happened in reading and listening. Moreover, the results suggested the combination of reading and listening activities in classroom activities.

Abstract:
While reading activity is a complex phenomenon, recent research on reading strategies has not provided comprehensive explanation of the role and perceptions of teachers regarding appropriate reading strategies helping students with learning difficulties. This paper is aimed to provide a sketch of the teacher's views and strategies to facilitate students with appropriate reading strategies. EFL teachers have different kinds of reading strategies applied in the classrooms. This study has found that three groups of teachers teaching in excellent accredited public schools, good accredited public school and very good Islamic private school use various strategies during the teaching of reading. Teachers' perceptions on the teaching of reading strategies are closely related to their readiness with knowledge about reading strategies, students' reading problems and their belief. This study suggests that EFL teachers and future researchers need to continuously investigate effective teaching of reading skill in relation to students' reading strategies.

Abstract:
The potential of thin layer in many applications has led to research on the development of many new materials and their fabrication methods. This study aimed to synthesize a thin layer of ZnO using the facile and low-cost sol-gel spin coating method. The ZnO thin layer is deposited on a glass substrate and analyzed to observe the influence of the deposition variables such as heating and rotation speed, and its aging. The characterization methods include the identification of the formed phase using X-Ray Diffractometer (XRD), and the microstructure and elemental composition using Scanning Electron Microscopy (SEM) coupled with EDS (Energy Dispersive Spectrometer). The study shows that a thin layer of ZnO is successfully deposited on a glass substrate by heat treatment at temperatures of 300 oC and 500 oC. Furthermore, XRD reveals that higher heating temperatures result in higher diffraction peak intensity. At a heating temperature of 300 °C crystals are formed but are not yet perfectly oriented, while they are at 500 °C. On the other hand, higher spin coating rotation speed gives rise to lower intensity of diffraction peak. The ZnO crystallization is easier to form in the coating process with a lower rotation (1500 rpm). Interestingly, the thin layer is stable over time where there is no significant change in each sample, both in terms of intensity and width of the ZnO crystal peak. The results indicate that gel precursor aged less than two days can form ZnO crystals. Finally, SEM results show that the surface morphology of the ZnO layer heated at 500 oC has an average grain size of 300 nm. Based on the cross-sectional results of SEM shows that the higher the coating rotation speed has resulted the thinner of the ZnO layer, where the thickness of the resulting layer is on order >5 mm.

Abstract:
The rGO/Fe3O4 composite is one type of composites that can be used as a biosensor material, especially glucose sensors. The main ingredients of the composite synthesis are graphite and iron sand. The synthesis process of Fe3O4 was done using the coprecipitation method, while the graphite oxidation process was accomplished using the modified Hummer's method. The composites were formed using the ex-situ wet mixing method. The formed iron sand and graphite were characterized using FTIR and XRD, and it was found that Fe3O4 was formed from the appearance of the Fe-O bond, the oxidation process of graphite was seen from the appearance of the C=O bond, and the detection of Fe peaks corresponded to the cubic crystal plane. Likewise, the composites formed were also characterized using FTIR and XRD for identification of the rGO/Fe3O4 composite formation. It was proven from the presence of Fe-O and C-O bonds and the appearance of an amorphous peak of rGO in the XRD results. The performance of the rGO/Fe3O4 composites as the glucose biosensor was examined by varying the mass of Fe3O4 on the composite, using UV-Vis spectroscopy. The performance of the rGO/Fe3O4 composite biosensor in absorbing glucose reached optimum at a mass variation of 0.3 grams of Fe3O4, as demonstrated by by the lowest absorbance peak with an intensity of 0.0048 at a wavelength of 440 nm, corresponding to glucose entrappment of 7.1 mg/gram.

This study was a qualitative research with a phenomenological approach. Data were collected from 408 students and 20 Lectures from 6 public universities and 6 private universities in Java, Sumatera, Kalimantan, Sulawesi, Nusa Tenggara, and Maluku, by filling out online questionaires and in-depth interviews via social media. The process of data analysis was data reduction, identifying themes, mapping interrelationships between themes, and concluding findings The results of data analysis showed that there were two main challenges, both for lecturers and students. First, limited resources, such as electronic devices (laptops/smartphones/others), learning resources, electricity, and internet connections. Second, lack of knowledge/skills on how to use the online learning media, finding and/or providing learning resources, managing online learning, providing online measuring tools, and carrying out online assessments. This condition has the greatest impact on students from low economic families, and who live in areas with limited access to learning facilities, such as electricity, and internet connections. Most of them lose learning opportunities because of these limitations. Third, the difficulty of time management during the online learning period.

Abstract:
This research is motivated by the awareness of the importance of community preparedness against disasters, especially for island communities whose locations are in disaster-prone areas. Maringkik Island, East Lombok Regency was chosen as the research location because the island is included in the southern part of Lombok Island which has the potential for megathrust with earthquakes above 8 SR. The objectives of this study were to determine: (1) the level of community education in Maringkik Island and its effect on community readiness in dealing with current disasters, (2) the level of understanding of disaster preparedness in the community in patron-client relationships, and (3) the level of disaster preparedness in the local social system of community in Maringkik Island, East Lombok Regency. The method used in this research is mixed methods, a combination of quantitative and qualitative research. The data were collected using in-depth interviews and surveys using a questionnaire that had been prepared. The results obtained from this study are that community preparedness in facing disasters is influenced by several factors, namely the level of education and knowledge as well as existing socio-cultural values. In addition, the existing patron-client pattern actually contributes to the community's low understanding of disaster preparedness. Community behavior and preparedness in the event of a disaster are still traditional, instinctive and natural, not based on modern science. Therefore, this study recommends the importance of disaster-specific subjects in schools and routine disaster mitigation-related training from related institutions.

Abstract:
This article reports the effectiveness of student-initiated media in teaching speaking to ninth graders of a junior high school. Using a pre-experimental design, this study involved 85 students, being given an experimental treatment in the form of a freedom to choose and use their own media to present an English advertisement, one of the basic competences the students had to master in the semester when the data were being collected. A pre-test in the form of oral interview was given at the beginning of the study, followed by the implementation of the research treatment. At the end of the study, the students took a post-test of a similar format. In other words, the data in this study were in the form of the students’ speaking performance. With the help of SPSS, a test was employed to check the effectiveness of the media. Besides, informal interview with the students show that they felt more relaxed and less anxious when using the media while speaking. It is recommended that teachers make use of such media in the classroom for designing democratic classroom atmosphere so that students experience joyful learning and tend to speak more.

Abstract:
The Covid 19 pandemic period has changed the learning system, including the presence of online learning. Literature reviews from various sources state that the Flipped Learning model is an alternative model for planned online learning. Even so, the Flipped Learning model cannot be implemented directly, but it must be adapted to the conditions where students learn. The development of the Flipped Learning model in this study is supported by a Moodle-based e-learning campus, which is called MyBrilian, through the following syntax: (1) Introduction, (2) Exploration, (3) Study, (4) Exposure, and (5) Assessment. This study involved 66 students of Information System study program of Universitas Dinamika who took Basic Mathematics courses. The instrument used is the Lesson Plans, Student Learning Materials and Test Instruments. Data analysis through statistical descriptive and qualitative descriptive techniques. Based on the data analysis, it can be concluded that the learning is classified into increased knowledge on a high scale, namely N-Gain of 0.7, and based on student response questionnaire, it shows satisfactory results in each syntax. The conclusion is that the flipped learning model can be adopted as an implementation of planned online learning, by adjusting to local learning conditions and with the support of technology.

Abstract:
As the forefront in fiber materials development, electrospun nanofiber membrane (NFM) is potentially reliable for wastewater treatment due to its excellent properties for instance; large surface area, high porosity, tuneable pore size, and has great flux as compared to other conventional membranes. However, fouling issue will lead to degradation of membrane performance. Fouling issue can be alleviated by applying membrane surface modification. In this study, thermal annealing is applied onto nylon 6,6 nanofiber membrane with three different temperatures (60°C, 80°C and 120°C). Results show that annealing causes membrane shrinkage and reduction of membrane fiber diameter where the fiber reduced from 138.5 nm to 108.5 nm when annealed at 120°C. The optimum annealing temperature for the membrane was found to be at 60˚C as the membrane shows the highest flux at 1200 L/m2.h at 75 minutes filtration time and took longer time to get fouled (>75 minutes) compared with un-annealed membrane (55 minutes). Nylon 6,6 nanofiber membrane is also proven to give more than 90% of COD and turbidity rejection.

Abstract:
Tujuan penelitian ini adalah mendeskripsikan secara komprehensif perbedaan bukti yang membuktikan dan bukti yang menjelaskan berdasarkan pertimbangan implikasi kedua bukti tersebut sebagai dasar konstruksi penalaran dan bukti dalam matematika. Kajian dijalani dengan kegiatan menguraikan perbedaan spesifik antara keduanya serta memberikan contoh kasus kedua bukti, dan memberikan justifikasi atas pentingnya pengenalan kedua bukti dalam kelas matematika. Kedua bukti digambarkan dengan permasalahan konsep barisan bilangan ganjil. Bukti yang membuktikan hanya menunjukkan dengan menggunakan induksi matematis, sementara bukti yang menjelaskan menunjukkan dengan bukti Gauss, representasi geometrik bangun titik, dan garis zig-zag. Perbedaan antara keduanya tampak pada pemberian alasan yang berasal dari bukti itu sendiri. Hasil kajian mengindikasikan bahwa peran bukti dalam kelas matematika pada tingkat perguruan tinggi adalah membuktikan/meyakinkan, pada tingkat menengah atas adalah membuktikan dan menjelaskan, dan pada tingkat sekolah menengah pertama dan dasar peran utamanya adalah menjelaskan. Akibatnya bukti matematis tidak hanya membuktikan/menyakinkan, melainkan juga menjelaskan. Karenanya penting mempertimbangkan implikasi bukti dalam kurikulum matematika di sekolah, serta perlunya menyajikan bab materi kepada mahasiswa pendidikan matematika tidak hanya bukti yang membuktikan, melainkan juga bukti yang menjelaskan.Proofs that Prove and Proofs that Explain in Mathematics ClassroomAbstractThe purpose of this study was to comprehensively describe the differences of the proofs that prove and proofs that explain based on the consideration of the implications of the two proofs as the basis for the construction reasoning and proofs in mathematics. The study was undertaken with the activity of describing the specific differences between the two and providing examples of cases of both proofs; and provide justification for the importance of introducing both proofs in mathematics classrooms. Both proofs are illustrated by the problem of the odd number sequence concept. Proofs that prove is only shown using mathematical induction, while proofs that explain shows with Gaussian proof, a geometric representation of point shape, and zigzag line. The difference between the two appears to be the reasoning that comes from the proof itself. The results of the study indicate that the role of proof in mathematics classes at the tertiary level is proving/convincing, at the senior secondary level it is proving and explaining, and at the junior and elementary school level its main role is explaining. As a result, mathematical proof does not only prove/convince, but also explain. It is therefore important to consider the implications of proof in the mathematics curriculum in schools, as well as the need to present chapter materials to mathematics education students not only proofs that prove but also proof that explain.

Salah satu rekomendasi asesor pada visitasi BAN PT dalam rangka Akreditasi Jurusan Tadris IPA Biologi, Fakultas Tarbiyah dan Keguruan UIN Mataram adalah praktikum Laboratorium IPA dilakukan dengan pola 10x1, sementara penyelenggaraan praktikum yang umum dilaksanakan adalah pola blok 1x10. Tujuan penelitian eksperimental ini adalah menguji efektivitas penyelenggaraan praktikum pola blok 1x10 dan 10x1 sebagai acuan kebijakan praktikum Laboratorium IPA. Efektivitas dilihat dari tiga komponen, yaitu: nilai tes praktikum, nilai laporan praktikum, dan preferensi praktikan dan co-asisten terhadap salah satu pola praktikum. Penelitian dilakukan pada mahasiswa Jurusan S1 PGMI Semester II, Jurusan Tadris IPA Biologi Semester IV, dan Co-Asisten. Rancangan penelitian adalah quasi eksperimental dengan tipe Pre-test–postest Non-Equivalen pada sampel yang diambil secara cluster random sampling. Data dikumpulkan dengan teknik tes, angket, dan wawancara untuk kemudian dianalisis dengan statistik inferensial pada taraf signifikansi 0,05. Hasil penelitian menunjukkan, bahwa nilai tes dan nilai laporan praktikum mahasiswa yang mengikuti praktikum pola blok 10 x 1 lebih tinggi dibanding 1 x 10, tetapi tidak berbeda secara signifikan. Berdasarkan analisis diperoleh 96% mahasiswa lebih menyukai pola praktikum 10 x 1. Dengan demikian, ditinjau dari hasil, salah satu pola praktikum tidak ada yang lebih efektif dibanding yang lain.Organizing Practicum of 1 X 10 and 10 X 1 Block Patterns as a Reference for Science Laboratory Practicum PolicyAbstractOne of the recommendations from BAN PT assessors during the visitation in the Accreditation of Department of Natural Sciences, Faculty of Education and Teacher Training is that practicum at Natural Science Laboratory should be administered in a 10x1 block pattern, while the general administration of practicum pattern is a 1x10 block pattern. This experiment aimed at investigating the effectiveness of the administration of the 1x10 and 10x1 block practicum patterns. The effectiveness was sought out by assessing three components, namely: practicum test scores, practicum report scores and the preferences of practicants and co-assistants to one of the practicum patterns. The participants of this study were the second year undergraduate students of elemetary Education Department and the fourh year undergraduate students of Natural Science Education Department, and co-sssistants. This study was of quasi-experiment using Non-Equivalent Pre-test-postest design and the sample was taken using cluster random sampling technique. The data were collected through test, questionnaire, and interview and then they were analyzed using inferential statistics at the 0.05. significance level. The findings showed that the test and practicum report scores of the students who joined the 10 x 1 block practicum pattern were higher than those who joined 1 x 10 block practicum pattern, yet they did not differ significantly. Based on the analysis, 96% of the students obviously preferred the 10 x 1 block practicum pattern. Thus, based on the results, no one practicum pattern was more effective than the other.
