Abstract

The purposes of this research were to investigate the synthesized Nylon-6 nanofibers using electrospinning technique and their characteristics. The method used in this study was an experimental method with a quantitative approach. Nylon-6 nanofibers have been produced using the electrospinning method. This fiber was made with different concentrations, i.e. 20% w/w (FN1), 25% w/w (FN2), and 30% w/w (FN3). The SEM results show that the morphology of all nylon-6 nanofibers) forms perfect fibers without bead fiber. Increasing fiber concentration from 20% w/w to 30% w/w results in bigger morphology and fiber diameter. The dimensions of the FN1, FN2, and FN3 fibers are 1890 nm, 2350 nm, and 2420 nm, respectively. The results of FTIR analysis showed that the increase in the concentration of nylon-6 (b) and the electrospinning process caused a peak shift in the amide II group (CH2 bond), the carbonyl group and the CH2 stretching of the amide III group from small wave numbers to larger ones. The results of XRD characterization showed that the electrospinning process affected the changes in the XRD pattern of nylon-6 nanofiber (FN1, FN2, and FN3) in the state of semi crystal. Nylon-6 nanofibers can be used for applications in medicine, air filters, and electrode for capacitors

Abstract

The electrospinning method has been used successfully to make polyvinylpyrrolidone nanofiber containing Anredera cordifolia leaves (BLE). The research methods used were qualitative and pure experiment method. Polyvinilpirolidone nanofibers containing BLE were prepared with three mass variations of the polyvinylpyrrolidone (% w/w), namely 12%, 10%, and 8% w/w, respectively. The results of the macroscopic photo show that the fiber structure looks white for PVP nanofibers and yellow for PVP/BLE nanofibers. The fiber morphology was analyzed using SEM and the results showed that PVP and all PVP/BLE nanofibers were like a continuous strand of crossbars with a diameter of 590 – 1190 nm. The decrease in the concentration of the PVP polymer led to a reduction in the diameter of the resulting nanofibers. The coefficients of variance (ε), of the PVP, BLE1, BLE2, and BLE3 nanofibers were 0.06, 0.09, 0.11, and 1.22, respectively. The physicochemical structure of the nanofibers was evaluated using XRD and FTIR. The chemical analysis (FTIR) showed that there was a molecular interaction between Anredera cordifolia leaves extract and polyvinylpyrrolidone in the form of hydrogen bonds. The physics analysis (XRD) shows the effect of the electrospinning process, which is to change the structure of BLE crystals to semi crystals. The application of PVP/BLE nanofiber for wounds dressing

Abstract

Nanofibers are nanotechnologies with cross-sectional diameters ranging from tens to hundreds of nanometers. We explained the definition of nanofibers and their unique physicochemical characteristics. This study aimed to see the characterization of Polyvinyl pyrrolidone/Cellulose acetate/Aloe vera extract fiber. The fiber was made with a concentration of PVP/CA in 13% (w/w) and an Aloe vera extract in 10% (w/w) using the electrospinning method. The electrospinning technique involves an electrohydrodynamic process in which liquid polymer droplets are electrified to produce jets that elongate to produce fibers. Electrospinning is an easy, fast, and simple technique for producing fibers with sizes ranging from micrometers to nanometers. Process parameters used in this research, such as flow rate of 0,20 ml/hour, high voltage of 12 kV, and drum speed is 200 rpm with the distance to the needle tip of the collector is 75 cm. The result showed that fiber PVP/CA/AE morphology is bead free and homogeneous. The average diameter of PVP/CA/AE fibers was 1115 nm.These results indicate that the resulting fiber is in the form of nanofibers. A small fiber diameter will result in a broader surface area. The XRD result shows that the PVP/CA/AE fibers have a semi-crystal phase.

Abstract

Flipped classroom is a sort of blended learning in which students learn both synchronously and asynchronously. Synchronous learning has taken place in the classroom in real time. Learners gather feedback while communicating with teachers and classmates at the same time. This review expects to figure out how is the execution and effect of Flipped Classroom in Science Learning (Contextual analysis During the Covid-19 Pandemic) of Class VIII at SMPN 3 Rantau Bayur. This study used a case study as an approach in exploring qualitative data. This examination is a distinct subjective exploration as a contextual analysis with information assortment methods as polls and meetings. The results of this review demonstrate that the execution and effect of flipped classroom in science learning during the Covid-19 pandemic is positive, particularly for class VIII students in science subjects at SMPN 3 Rantau Bayur with a typical rate gain of 76.7% or the category of ‘very good’. Through the flipped classroom, students have the opportunity to concentrate on the topic at home as they are free to set their learning time. Students become familiar with the topic in an enjoyable situation. Students can repeat the learning videos and they are able to access them from anywhere. Besides, parents can participate in learning activities outside the classroom and make time to help their children learn. However, one of the drawbacks is the lack of devices to watch videos given by the teacher as not all students have computers, laptops, or smartphones. Also, the teachers still find difficulties in preparing good quality videos as learning media for students.

Abstract

Teachers need to improve students’ creative thinking skills by incorporating relevant everyday contexts. Soccer, as a familiar part of daily life, has not been widely used in education, and its impact on creative thinking requires further study. This research aimed to develop a contextual physics e-module centered on soccer to enhance creative thinking in physics learning. The study followed Rowntree's development model, including planning, development, and evaluation, with Tessmer’s formative evaluation through expert reviews, one-on-one assessments, small-group evaluations, and field tests. The creative thinking indicators used in the research are fluency, flexibility, originality, and elaboration. Data were collected from 346 high school students in Palembang via walkthroughs, questionnaires, and written tests, then analyzed using SPSS version 16. The results showed that the soccer-based physics e-module is valid (Sig. 0.00), practical (one-to-one: 82.75%; small group: 91.00%), and in the moderate category for improving creative thinking (N-gain: 0.59). These findings highlight the need to explore other everyday contexts and assess the long-term impact of the e-module across different educational settings.

Abstract

Educational transformation in the Industrial Revolution 4.0 era demands that teachers adapt to digital technology and develop innovation-based learning. However, the results of a preliminary survey indicated that a majority of teachers at SMAN 10 Palembang lacked skills in creating digital learning media and were unfamiliar with Augmented Reality (AR) technology. This community service activity aimed to improve teacher competence through mentoring in the creation of AR-based interactive e-modules as a 21st-century learning innovation. The implementation methods included socialization, technical training, a coaching clinic, and an evaluation of outcomes using a pre-test, post-test, and a participant satisfaction survey. Fifteen teachers actively participated in this activity. The paired sample t-test analysis revealed a significant increase between the pre-test (M = 47.00; SD = 7.75) and post-test scores (M = 91.67; SD = 4,87), with t = –18.506, p = 0.000 (p < 0.05). And the Cohen’s d = 9.35, categorized as a very large effect. This finding demonstrates that the mentoring program was effective in enhancing teacher competence in developing AR-based interactive e-modules. Furthermore, the results of the participant satisfaction survey reinforced the program's effectiveness. A total of 73.3% of participants stated they were "very satisfied" with the quality of the mentoring and facilitators, while 80% felt their e-module creation skills had significantly increased. Regarding the AR integration aspect, 87% of participants expressed high satisfaction with the clarity of the training and the implementation results. Meanwhile, 67% rated the activity as having a direct impact on enhancing their instructional technology integration skills. All participants demonstrated a high commitment to sustainably implementing the training outcomes in their respective schools. Consequently, this program is proven to have a positive impact on enhancing digital literacy, pedagogical competence, and teacher readiness to face the challenges of 21st-century, technology-based learning.

Abstract

Critical thinking is increasingly recognized as an essential skill for vocational high school students. However, teachers in South Sumatra report that students’ performance remains limited, particularly in advanced clarification, decision-making, and complex reasoning. This study represents one of the first regional analyses of IPAS teachers’ perceptions regarding critical thinking and the integration of STEM-based digital games in Indonesian vocational schools. Employing a quantitative descriptive approach, the study involved 118 IPAS teachers from various regions. Findings indicate that 57% of teachers stated that only some students were able to conduct observations and compile reports, while 53% reported that only a few students could anticipate logical consequences. Overall, teachers noted that digital learning facilities such as communication devices, internet access, and presentation media were available, although their distribution varied across schools. Most teachers also expressed positive attitudes toward the use of STEM-based digital educational games, viewing them as an effective medium for enhancing student engagement and strengthening critical thinking in IPAS learning. These results emphasize how important it is to develop STEM-based digital educational games as a strategic solution for improving critical thinking skills in vocational education
