Abstract

The acid hydrolysis method was used to extract nanocellulose from bagasse. This study aims to prepare nanocellulose from sugarcane bagasse by acid hydrolysis method and to know the results of characterization with X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTIR). In this study, 4 samples were made with variations of H2SO4 of 19, 29, 39 and 45%. XRD analysis shows that with the increase of sulfuric acid, the percentage of each sample increases, but in the 39% sample, there is a decrease in purity because there are still areas of cellulose that have yet to disappear. The phase identification results show that in the sample with 19, 29, and 39% addition, H2SO4 Iα, Iβ, and thenardite phases were formed. In the sample, 45% only form Iα and Iβ phases with a resulting particle size of 2.83 nm and a degree of crystallinity of 55.52%. The results of the SEM test analysis show that the image pattern has stone structures that overlap each other. The results of FTIR analysis show that the functional groups detected are O – H, C – H, C ≡ C, C = C, H – C – H, C – O, and C – O – C, which indicates the presence of nanocellulose.

Abstract

Lucutan corona merupakan salah satu bentuk teknologi plasma dingin yang menjanjikan dalam aplikasi sterilisasi karena kemampuannya menghasilkan radikal oksigen reaktif (ROS) yang efektif dalam menonaktifkan mikroorganisme. Penelitian ini mengkaji karakteristik geometri, konfigurasi elektroda, serta parameter operasi lucutan corona dalam berbagai studi yang telah dipublikasikan. Hasil analisis menunjukkan bahwa konfigurasi pin-to-plate lebih banyak digunakan dibandingkan surface discharge karena kemampuannya menghasilkan medan listrik terfokus dengan intensitas tinggi. Tegangan operasi berkisar antara 10–30 kV dengan frekuensi 0.5–20 kHz, tergantung pada lingkungan bakteri uji. Beberapa jenis bakteri patogen, seperti Pseudomonas aeruginosa, Staphylococcus aureus, Serratia liquefaciens, Salmonella typhimurium, Listeria monocytogene, dan Escherichia coli, terbukti dapat dinonaktifkan secara efektif oleh plasma corona. Namun, tantangan dalam optimasi parameter, efisiensi energi, dan penerapan dalam skala industri masih menjadi hambatan yang perlu diselesaikan. Oleh karena itu, diperlukan penelitian lebih lanjut untuk meningkatkan efektivitas dan efisiensi teknologi ini dalam berbagai aplikasi, termasuk di bidang medis, pangan, dan pengolahan limbah.

Abstract

This article presents a comparative semiotic analysis of Ramadhan campaign advertisements from two Southeast Asian technology giants, Gojek (“#Mauramadhanfull”) and Grab (“#Grabinramadhan”). Employing Roland Barthes’ theoretical framework: denotation, connotation, and myth. This research dissects how both brands construct different meanings and ideologies within the unique cultural and commercial landscape of Ramadhan in Indonesia. The analysis finds that Gojek constructs a “Myth of Facilitated Piety,” positioning itself as an integral enabler for achieving a holistic and spiritually fulfilling Ramadan experience. Conversely, Grab constructs a “Myth of Instant Consumerist Fulfillment” through a meta-humorous narrative that deconstructs traditional advertising and promotes its platform as a magical solution for immediate desire fulfillment. This paper concludes that the competition between Gojek and Grab extends beyond service offerings. It is a semiotic battle to define the role of technology in contemporary religious practice, reflecting and actively shaping the intersection of tradition, consumerism, and digital life in Indonesia.

Abstract

Ability in using English will have a competitive advantage in building strong business relationships and understanding the needs of international customers. However, many bank employees face challenges in developing their English skills. Some of them may have limited access to adequate learning resources, while others may not have enough spare time to attend formal training. Moreover, some bank employees may feel less confident in using English in real business situations, such as interacting with foreign customers or participating in international meetings.  Therefore, through this community service program, we aim to address these obstacles and assist bank employees in developing the English skills necessary for success in an increasingly global banking environment. By providing intensive training, mentoring, and relevant learning resources, we hope to enhance the English competence of bank employees, strengthen their

Abstract

This study explores the effectiveness of higher-order thinking skills (HOTS) questions in fostering critical thinking among EFL learners in a Listening for Academic Purposes (LAP) class. While academic listening inherently involves cognitive processes such as inference, evaluation, and analysis, EFL instruction often focuses on lower-order comprehension tasks. To address this gap, the study implements HOTS-based questioning strategies within a Classroom Action Research (CAR) framework, promoting reflective teaching and continuous improvement. The research was conducted with six intermediate EFL students over two cycles, incorporating academic audio materials, structured HOTS questions, and student-centered discussions. Data were collected through observation checklists, student reflection sheets, and pre- and post-tests. Findings indicate that students initially struggled with higher-order questions but showed significant improvement in both critical thinking and listening performance after receiving appropriate scaffolding and practice. The post-test results and classroom observations revealed increased engagement, deeper analysis, and more thoughtful responses. This study concludes that integrating HOTS questions into LAP instruction can effectively enhance critical thinking skills in EFL learners. It also highlights the value of reflective teaching practices in adapting instructional strategies to meet learner needs. Implications are offered for language teachers, curriculum designers, and future researchers aiming to enrich listening pedagogy through critical thinking development.
