This article was presented in the 1st International Conference on Tropical Studies and Its Application (ICTROPS) in the year 2017. The pre-printed version title was "The earlier soybean suffers from aluminum stress, the more its vegetative growth is disrupted". Then, this article is published in IOP Conf. Series: Earth and Environmental Science titling "Effect of aluminum stress in early-stage growth of soybean". The change of the title was done as reviewer suggested. So, This is the post-printed version and reader can access the published version of this article in IOP Conf. Series: Earth and Environmental Science 144 (2018) 012067, doi :10.1088/1755-1315/144/1/012067

Course Development

Aims: With increasing emphasis on learners-centered approach in teaching and learning, engaging students in course development and refinement is crucial. This study aims to foster a participatory approach in course development by engaging students in meaningful discourse at the early stage of an atmospheric science course. Study design:  This is a qualitative study which employed the grounded theory for data analysis. Place and Duration of Study: The study was conducted in March 2021 in an international higher learning institution located in the Guangdong Province of China. Methodology: This qualitative study invited a year 3 cohort of environmental science students taking an atmospheric science and pollution course in an international higher learning institution in China to participate in a meaningful discourse about the course in week 2 of the semester. Their responses were transcribed and the transcripts analyzed with NVIVO based on the grounded theory. The transcripts were coded, the themes were drawn and the relationship was probed. Results: This study identified three overarching themes from the codes, namely assessment, course contents and learning activities, whose codes covered 4.5%, 17.8% and 23.1% of the text respectively. Codes for assessment comprise practical assignment and multiple-choice question, while those for course contents include black carbon, modelling, greenhouse gases, zero-carbon, and removal of Freon. Codes for learning activities include case studies, debate, field trips and quizzes. The words most frequently appeared in the transcripts are learning and field. The findings reflect expectations for interactive learning, simulation-based learning, authentic assignments and activities, experiential learning via field trips and problem-based learning. These are in line with the established pedagogies for environmental science. Conclusion: This study shifts the paradigm of students’ engagement in the increasingly learner-centered educational setting where students are proactively involved in course development in the early stage of teaching and learning instead of reactively involved through feedback collection at advanced stages.

ABSTRACT ShaA (sodium/hydrogen antiporter, previously termed YufT [or NtrA]), which is responsible for Na+/H+antiporter activity, is considered to be the major Na+excretion system in Bacillus subtilis. We found that ashaA-disrupted mutant of B. subtilis shows impaired sporulation but normal vegetative growth when the external Na+ concentration was increased in a low range. In theshaA mutant, ςH-dependent expression ofspo0A (PS) and spoVG at an early stage of sporulation was sensitive to external NaCl. The level of ςH protein was reduced by the addition of NaCl, while the expression of spo0H, which encodes ςH, was little affected, indicating that posttranscriptional control of ςH rather than spo0H transcription is affected by the addition of NaCl in the shaA mutant. Since this mutant is considered to have a diminished ability to maintain a low internal Na+ concentration, an increased level of internal Na+ may affect posttranscriptional control of ςH. Bypassing the phosphorelay by introducing thesof-1 mutation into this mutant did not restorespo0A (PS) expression, suggesting that disruption of shaA affects ςH accumulation, but does not interfere with the phosphorylation and phosphotransfer reactions of the phosphorelay. These results suggest that ShaA plays a significant role at an early stage of sporulation and not only during vegetative growth. Our findings raise the possibility that fine control of cytoplasmic ion levels, including control of the internal Na+ concentration, may be important for the progression of the sporulation process.

Excellency, Drs. Bedjo Santoso, MT. Ph. D., Rector Universitas Islam Sultan Agung; Honorable, Assoc. Prof. Dr. Mohd Ismid Bin Md Said, Pro-Vice Chancellor (International) UTM; Respectable, The distinguished guests and the participants, ladies and gentlemen. Welcome to the International Forum on Integrated Infrastructure Development (InFInID 2021) Hybrid Conference, which consists of 12th International Conference on Geotechnical Engineering in Tropical Regions (GEOTROPIKA), 2nd International Conference on Highway and Transportation Engineering (ICHITRA), and The 4th International Conference on Delta & Coastal Areas (ICCDA 4 2021), 21–22 September 2021. Due to the global health issue of coronavirus disease (COVID-19), InFInID 2021 is being held in mixed mode, offline and online. The conference is divided to Panel and Parallel session (7 parallel sessions, 3 rooms for 3 fields per session). I also want to inform that we will have ‘Best Paper’ Award for some topics and ‘Best Presenter’ Award for each session. For all presenters, do your best and catch the reward. The next step is publishing all paper to IOP Conference Series: Earth and Environmental Science, Scopus Index. May the conference run smoothly and the goals will be achieved. And last, but not least, I would like to thank you, our shareholders, for continuing to support us, in good times, and in difficult ones. Hope that the pandemic will leave us soon, and we will have the opportunity to meet again face to face. My best wishes to you all! Prof. Dr. Ir. S. Imam Wahyudi, DEA Chairman of ICCDA 4 List of Patrons, Advisors, Chairmen, Secretaries, Reviewer are avilable in this pdf.
