Abstract:
This study aimed to describe the challenges of higher education in implementing online learning during the pandemic Covid-19 outbreak. 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:
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.

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:
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:
The study aimed at reporting the perception and usage of community resources by Social Studies and Civic Education teachers in Delta State, South South, Nigeria. Two research questions and one hypothesis were raised to give the study a direction. A sample of 196 out of a population of 656 Social Studies and Civic Education teachers was used for this study. Instrumentation was done with researcher’s designed questionnaire with a reliability index of 0.89. Data was analyzed with percentage for research questions and Analysis of Variance (ANOVA) was used to test the hypothesis of the study. Findings of the study demonstrated that Social Studies and Civic Education teachers of public schools in Delta State perceive the use of community resources to be high for effective teaching but usage of the resources was relatively low. Hence the study concluded by recommending that spirited effort be made by all the stakeholders involved to employ the judicious use of community resources for Social Studies and Civic Education instructions in secondary schools of Delta State.

Abstract:
The STEM is an approach that seemly considered will be useful in online learning, because it can facilitate students to learn some skills from about 21st century. This study was aimed to develop module-based STEM in improving scientific literacy skills in distance learning through e learning. Because this research developed module-based STEM, this study was named developmental research. The research procedure follows the stages of the R & D method developed by Barg and Gall which includes the studies of preliminary, product planning, development, validation (validation by experts), and  revision, lastly field testing. Moduls that have been declared valid by experts are field tested using one group pretest-posttest design in an experimental class. The results show that the feasibility of module-based STEM in distance learning model to increase students' skills within scientific literacy was valid with the average score of 4.28 by two experts. In addition, the application of integrated STEM teaching materials through e-learning has a moderate effect on students' scientific literacy skills since the N-gain score was 0.6.

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:
This study investigates the culture-based instructional materials (C-BIM) model to improve students’ reading and writing skills viewed from critical thinking skills at the junior-high-school in Indonesia. This study is a mixed-method employing the explanatory sequential design. The data are in the form of quantitative and qualitative data. The quantitative data are collected first and followed by the quantitative one. The research instruments are in the form of reading and writing tests, questionnaires, and interview sheets. The test is used to see the students’ reading and writing achievements. Meanwhile, the questionnaire is utilized to determine the students’ and teachers’ intercultural awareness and perception of incorporating cultures in teaching materials. The data of reading-writing achievement are analyzed using descriptive and inferential statistics. Thus, the data of students’ and teachers’ cultural awareness and perception are gained by applying qualitative steps: analysis, reduction, coding, interpretation, and conclusion. Based on the result of the research, this study indicates that the C-BIM model significantly affects students’ reading and writing skills. Also, it has an interaction between teaching materials and critical thinking skills. Researchers elaborate on those in the discussion part of this article regarding the students' intercultural competence and perception.

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.
