Abstract

Separation process using a membrane is a common method used in many fields. The objective of this research is to find out the influence of polymer concentration on the physical properties and performance of cellulose acetate as an ultrafiltration membrane. The cellulose acetate membrane is made by phase inversion technique. This technique is carried at by dissolving cellulose acetate in a range of concentration (18%, 19%, 20%, 21%, and 22%) in the solvent (acetone/DMSO = 15%/60%) and DMP as additives (3% mL). Then the mixtures homogenized and added PEG400 for 10% of cellulose acetate concentration (% w/w), strired ± 12 hours left in place until the buble disappeared. Then the dope solution is printed the glass plate, evaporated for 3 minutes, and immersed in a coagulation bath containing 5% acetone. The results suggest that the greater the concentration of cellulose acetate membrane increase the number density while the swelling degree decrease. The performance of the membrane showed that the greater concentration of cellulose acetate will water of flux the membrane decrease and rejection coefficient increase. Cellulose acetate membrane by varying the concentration of 21% and 22% included in the classification of ultrafiltration membranes for rejection coefficient value (90,37% and 91,43%) 90% may rejection by a membrane.

Abstract

Rhetorical moves purposes to examine the basic structures of research articles, while meta discourse markers are elements to construct and to establish ideas and arguments. This study compares rhetorical moves and the function of meta discourse markers in research articles abstracts of different academic disciplines published in reputable indexed journals. This study employs (Pho, 2008)’s five-move analysis and the classification of meta discourse marker proposed by (Dafouz-Milne, 2008) as the research framework. The writer took five Indonesian Scopus Q1 and Q2 indexed journals from different academic disciplines. Those are Indonesian Journal Science and Technology (IJoST), Indonesian Journal of Applied Linguistics (IJAL), Journal on Mathematics and Education (JME), Studia Islamika and Forest and Society.  The results show that in terms of rhetorical move of abstracts, M2 and M4 became the moves which occur in all journal abstracts. In terms of meta discourse markers, all journal abstracts employ logical markers and code glosses. Sequencers, topicalisers, and illocutionary markers are used in small numbers, while reminders and announcements are not be found in any abstracts. The findings could help students and writers to produce abstracts that fulfill the requirements to be published in Scopus indexed journals.

Abstract

YouTubers, content creators, or vloggers link in some way to influence their viewers. Therefore, the use of creative languages and a good linguistic approach is crucial to convey the content of the videos. Deictic expression is a common and a universal feature in regular conversation as well as in written productions. Deixis features a word or a phrase that points out people as person deixis, time as temporal deixis, or place as spatial deixis. This study analyzes and compares the use of person deictic expressions from six videos taken from three Indonesian male food vloggers and three Indonesian female food vloggers who have the most subscribers. The findings show that there is a difference between Indonesian male and female food vloggers. While Indonesian male food vloggers are mostly use informal person deictic expression gue (English: I, informal style), Indonesian female food vloggers use formal-polite person deictic expression aku, saya (English: I, formal style). They also use kita (English: inclusive-we) to minimize the distance between them and the viewers, indicating that they are having the same experiences. The findings could help the readers and the YouTube viewers to understand the function of person deictic expression that is to place the food vloggers at the center of the situation

Abstract

Figurative language analysis in a novel involves examining the author's use of various literary devices and techniques to enhance the narrative, evoke emotions, and create a deeper understanding of the text. This analysis goes beyond the literal interpretation of words and delves into the layers of meaning and imagery that contribute to the overall richness of the story. The purpose of this study is to seek the types of figurative language found in the novel The Kite Runner written by Khaled Hosseini and to analyze their meanings. The Kite Runner is a historical fiction novel, sets in Afghanistan in the 1970s with the social and political conditions of the Soviet invasion and the rise of the Taliban dictator. Using descriptive qualitative content analysis, this study reveals that there are 72 sentences containing figurative language and there are nine types of figurative language. Those are metaphor (15%), simile (32%), personification and, synecdoche (9%), metonymy (13%), both paradox and symbol (4%), hyperbole (7%), and apostrophe (3%). The findings show that the dominant type of figurative language in the novel The Kite Runner is simile.  This study sheds light on the author of the novel The Kite Runner effective use of figurative language to enhance the narrative, convey emotions and enrich the readers’ experiences. Thus, this paper provides an in-depth analysis of figurative languages found in one of the great historical fictions.

Abstract

Metacognition, the reflection on thinking processes, plays a crucial role in cognitive activities. This study delves into metacognitive strategies employed during post-editing in the translation process, particularly focusing on English-Indonesian translation through the application of think-aloud protocols (TAP). The investigation encompasses planning, monitoring, and evaluation as interconnected phases of metacognitive strategies. A qualitative case study method is employed, with a university student as the participant. Data analysis involves coding and categorizing using a thematic analysis approach, based on the metacognitive strategies framework. The findings show that the participant employes the components of planning such as evaluate the necessity of post-editing, applied knowledge on the specific post-editing cases, and identified the goal and the necessity for having specific post-editing, the components of monitoring such as using facts and instruction learned previously, making changes for a better translation product, and self-monitoring of progress, and elements of evaluating, such as deep level revising to produce better post-editing, and taking action to collect extra information. Pedagogical implications highlight the potential for enhancing learning experiences and improving translation skills through explicit instruction, modeling and systemic strategy training. The study concludes by emphasizing the importance of metacognitive flexibility, cultural influences, and adaptive strategic behavior in post-editing, shaping a roadmap for learners to navigate challenges and continually refine their approach.

Abstract

This study explores the attitudes and valorization of languages among Indonesian engineering students at Cendikia Abditama University. Employing a qualitative research design, the study gathered data from 70 students through questionnaires, supplemented by in-depth interviews with 10 participants to gain richer perspectives. A descriptive analytical approach was used to interpret the findings, revealing a predominantly positive attitude toward English, Indonesian, and heritage languages. This demonstrates a nuanced balance between cultural pride, national identity, and the global opportunities associated with these languages. The research highlights that while many students value all three languages equally, others exhibit a preference for one language over the others, depending on their immediate academic, professional, or personal aspirations. These variations reflect the dynamic interplay between cultural heritage and global competitiveness in shaping language attitudes. The findings underline the critical role of educational policies in supporting linguistic diversity and fostering inclusive learning environments. By integrating students’ linguistic backgrounds into educational curricula, institutions can enhance learning experiences and promote multilingual competence. Such approaches can help prepare students for the challenges of a globalized world while maintaining their cultural roots, thereby contributing to more comprehensive and meaningful educational practices. This study emphasizes the significance of aligning language education with students' diverse needs and aspirations.

Abstract

Economic growth is a measure of the welfare of the Indonesian people. Over time, the factors that affect economic growth are growing. The emergence of Microfinance Institutions (MFIs) has its own impact on Indonesia's economic growth. This study aims to determine the effect of Microfinance Institutions on economic growth in Indonesia. By using the Random Effect Model (REM) panel data regression method covering 21 provinces in Indonesia in the 2019-2020 period, this study shows that, only the Labor variable is proven to have an effect on economic growth in Indonesia. While the variables for the number of MFIs and the amount of MSME loan funds have not been proven to have an effect on economic growth in Indonesia. This indicates that the human resource factor as a form of human capital is the main factor driving economic growth in Indonesia. So that the policy implication of this research is to encourage economic growth a policy to improve the quality of human resources is needed. Keywords: Economic Growth, Total Microfinance, Labor, REM
