SELECTION OF OPTIMAL TECHNOLOGICAL PARAMETERS FOR FORMING NOMINALLY FLAT SURFACES WITH LUBRICATING MICROCAVITIES
Authors: Kuznetsov Viktor P. , Tatarintsev Igor V. , Voropaev Vladimir V. , Korelin Andrei V.
Published: October 2024

This article demonstrates a multi-step process for forming a nominally flat surface with circumferential lubricating microcavities on a tribological assembly of an Х38CrSi steel shaft. The process includes finish turning, preliminary strengthening burnishing, deformation profiling of microcavities by a honing stone and smoothing of microprotrusions. The study determines the optimal technological parameters for each of the transitions based on microhardness and oil absorption power maximization, as well as roughness and periodic impact minimization. The process optimization is conducted using the Tagichi experiment design method. The optimal combination of technological parameters for hardening burnishing was discovered to be: normal force F = 200 N; feed rate f = 0.025 mm/rev and three tool passes. These burnishing parameters practically eliminate the influence of periodic impacts at spatial frequencies determined by the tool feed rate and the number of spindle rotations during turning. We determined suitable honing stone grit parameters and application force that yield microcavities 3.8 to 8.1 μm in depth, as well as the optimal parameters for smoothing of microprotrusions, resulting in a bearing area roughness of Sa = 0.15 µm and oil absorption power of 13.74×10–5 mm3/mm2.

Authors: Wilhayn Josefine , Lyashenko Iakov A. , Li Qiang , Popov Valentin L.
Published: October 2024

Influence of tangential force on the adhesive contact, in particular on the adhesive strength and the contact area have been a subject of investigation and discussions for many years. Depending on the system under consideration, both increase and decrease of adhesion strength due to shearing of an adhesive contact have been reported. The same is valid for change of the contact area. While it is generally accepted that the contact area decreases when applying tangential traction, also opposite behaviour is possible. In the present paper we study theoretically and experimentally the conditions under which the contact area may increase or decrease due to shear.

Authors: Ullah Kifayat , Ahmad Junaid , Khan Benish
Published: October 2024

Let $H$ be a nonempty subset of a Banach space $X$. A mapping$T:H\rightarrow H$ is said to be generalized $\alpha$-nonexpansive if there is a realnumber $\alpha\in[0,1)$ such that for all $x,y\in H$, we have\begin{eqnarray*}\frac{1}{2}||x-Tx||\leq||x-y||\end{eqnarray*}\begin{eqnarray*}||Tx-Ty||\leq\alpha||Tx-Ty||+\alpha||Ty-x||+(1-2\alpha)||x-y||.\end{eqnarray*}In this paper, we obtain some weak and strong convergence theoremsfor such mappings using K-iteration process in uniformly convex Banach space setting. Our results extend and improve many results in the literature.
ROUGH IDEAL CONVERGENCE OF DOUBLE SEQUENCES IN INTUITIONISTIC FUZZY NORMED SPACES
Authors: Mondal Rahul , Hossain Nesar
Published: October 2024

The idea of rough statistical convergence for double sequences was studied by Ozcan and Or [34] in a intuitionistic fuzzy normed space. Recently the same has been generalized in the ideal context by Hossain and Banerjee [17] for sequences. Here in this paper we have discussed the idea of rough ideal convergence of double sequences in intuitionistic fuzzy normed spaces generalizing the idea of rough statistical convergence of double sequences. Also we have defined rough I2-cluster points for a double sequence and also investigated some of the basic properties associated with rough I2-limit set of a double sequence in a intuitionistic fuzzy normed space.
SOME REMARKS ON LOCALLY NOETHERIAN AND LOCALLY ARTINIAN S-ACTS OVER MONOIDS
Authors: Khosravi Roghaieh , Roueentan Mohammad , Rahimi Elham
Published: October 2024

In the category of S-acts, artinian S-acts are introduced as the acts that satisfy the descending chain condition on its congruences. Noetherian S-acts are also the acts that satisfy the ascending chain condition on its congruences. Rees noetherian and Rees artinian case is defined using Rees congruence. This paper is devoted to study the classes of locally artinian, locally artinian, locally Rees artinian and locally Rees artinian S-acts. An S-act is said to be locally artinian if all its finitely generated subacts artinian. The noetherian, Rees noetherian and Rees artinian case is defined similarly. We give some general properties of these classes of S-acts, specially discuss the behaviour of such acts under Rees short exact sequence and coproduct. Finally, we establish some connections between some classes of S-acts such as projectivity and injectivity with the notions related to locally artinian and locally noetherian.

Published: October 2024

This work investigates the contributions of the problem-solving (PS) methodology to the teaching of electrochemistry from an STS (science, technology, and society) perspective. The research was undertaken with 82 students from four classes of the 3rd year of high school, at a state public school in the metropolitan region of Porto Alegre (Rio Grande do Sul state, Brazil). Two problems were used, both complying with the characteristics of an effective problem. The research data were obtained from the problem solutions proposed by the students, as well as from the records in the field diary of the researcher. These documents were examined by content analysis, based on categories defined a priori. Analysis of the results showed that the PS methodology contributed to the learning of the students and enabled association between the electrochemistry contents and technological, social, and environmental issues.

Compaction Characteristics of Fly Ash and Pond Ash: A Comparative Analysis
Authors: . Chandrakant
Published: October 2024

This study investigates the compaction characteristics of Fly Ash and Pond Ash, which are by-products of coal combustion in thermal power plants. Thermal power plants generate three types of ash: (a) Fly Ash, (b) Pond Ash, and (c) Bottom Ash. Fly Ash consists of fine particles carried out of the boiler with flue gases, while Bottom Ash is the residue that settles at the bottom of the boiler. In most coal plants, Fly Ash is captured using electrostatic precipitators and other filtration equipment before the flue gases are released through the chimney. Pond Ash, on the other hand, is a by-product of thermoelectric power plants, often regarded as waste material, posing significant environmental disposal challenges. The compaction characteristics of Fly Ash and Pond Ash are influenced by various factors, including specific gravity, moisture content, compaction energy, layer thickness, and mold area. In this study, Fly Ash collected from NTPC Sipat , Chhattisgarh exhibited an Optimum Moisture Content (OMC) ranging from 18% to 27% and a Maximum Dry Density (MDD) ranging from 0.90 to 1.59 gm/cc under standard Proctor compaction energy. Similarly, Pond Ash demonstrated an OMC ranging from 33% to 46% and an MDD ranging from 0.856 to 1.248 gm/cc under the same conditions. The findings indicate that variations in these factors significantly affect the dry density of both Fly Ash and Pond Ash. The study also aims to determine the geotechnical properties of these materials, providing insights into their potential applications in engineering and environmental management

Authors: Silva Leonardo Mendes da , Silva Fábio Júnio da
Published: October 2024

A Curcuma longa é uma planta de valor medicinal, conhecida popularmente como açafrão ou cúrcuma. Os rizomas desta planta são ricos em curcuminóides, compostos responsáveis pela atividade farmacológica. Devido ao aumento do consumo desta planta na população em geral, este estudo teve como propósito avaliar o potencial tóxico do extrato aquoso obtido a partir dos rizomas de Curcuma longa, utilizando o bioensaio com Artemia salina. Os cistos de Artemia salina foram incubados por um período de 30 horas, seguido do recolhimento dos náuplios que foram posteriormente expostos a diferentes concentrações do extrato obtido por meio de decocção (50, 100, 200, 400 e 800 μg/mL-1). Para cada tratamento empregou-se quatro repetições. Os náuplios (10 por repetição) foram mantidos em contato com a solução por 48 horas, e a taxa de sobrevivência foi avaliada a cada intervalo de 24 horas. Após 24 horas de exposição ao extrato aquoso, não foi observada mortalidade significativa em nenhuma das concentrações avaliadas. No entanto, após 48 horas de exposição, verificou-se mortalidade significativa a partir da concentração de 100 μg/mL-1, resultando em uma taxa de mortalidade de 32,35%. Na concentração intermediária (400 μg/mL-1), observou-se uma taxa de mortalidade de 61,76%, enquanto na concentração mais alta (800 μg/mL-1), registrou-se 100% de mortalidade dos organismos expostos. A concentração letal média (CL50) obtida foi de 186,5 μg/mL-1, classificando assim o extrato aquoso como moderadamente tóxico. Portanto, é recomendado precaução ao utilizar o chá desta planta, uma vez que o extrato aquoso demonstrou toxicidade em relação à Artemia salina.
Dreams, Trauma, and Prediction Errors
Authors: Bonamino Clarita , Boudrias Sophie , Rosen Melanie
Published: October 2024

It is widely known that dreams can be strongly affected by traumatic events, but there may be other ways in which dreams relate to trauma. In this paper, we argue that different types of dreams could both contribute to trauma and alleviate it according to the prediction errors that occur either in dreams or in response to them after waking. A prediction error occurs when an experience contradicts one’s expectation and it is often accompanied by surprise. Prediction errors are involved in memory updating processes that can be long-lasting. Not only nightmares but also unpleasant, and surprisingly, even neutral and pleasant dreams have the potential to contribute to trauma, affecting our waking lives in a similar way to waking traumatic experiences. We postulate that certain dreams can also be beneficial for trauma alleviation. Further, clinical evidence suggests that working with prediction errors that occurred in dreams and during our response to dreams after waking can assist in alleviating the negative effects of trauma.
Trauma, Dissociation, and Relational Authenticity
Authors: Maiese Michelle
Published: October 2024

Relational trauma can be understood as a psychological injury that occurs in the context of abusive interpersonal relationships and appears to be correlated with a wide array of mental illnesses. However, one potential harm of trauma that has not received much attention from philosophers is the threat it poses to authenticity. To understand why relational trauma potentially creates impediments to authentic agency, we need to consider two other phenomena that are commonly associated with it: (i) dissociation, and (ii) diminished habitual trust. Whereas trauma-related dissociation commonly involves bodily alienation and detachment from the self, diminished habitual trust often leads to alienation from others. I maintain that dissociative detachment and diminished habitual trust often are mutually reinforcing and that, together, they can cause agents to become disconnected from themselves, others, and the reality of what has happened to them. What implications does this have for authentic agency among traumatized individuals? After outlining existing conceptions, I emphasize the important sense in which authenticity is relational and scaffolded by social connections. I also discuss several competencies that undergird authenticity and argue that the interplay between dissociative detachment and attenuated habitual trust can make it difficult for traumatized individuals to develop and sustain these competencies. Thus, the trauma they have experienced impedes their ability to conduct their lives in accordance with their genuine cares and desires.

Digital transformation of international trade and logistics in the conditions of pandemics and military conflicts
Authors: Dumanska Ilona
Published: October 2024

The purpose of the publication is to provide a scientific and theoretical justification of the cause-and-effect relationships from pandemics and military conflicts to the acceleration of the digital transformation of international trade and logistics and the development of the IT segment in the world for these needs. It has been proven that the COVID-19 pandemic and military conflicts have accelerated and promoted the digital transformation of international trade and logistics, adapting them to the needs of life in a new social reality. It was established that the gaps in the digital transformation of business are related to the differentiation of the digital development phases of companies and the lack of a standardized approach to the functioning of a single digital platform for the implementation of IT changes. The interrelationship and influence of Industry 4.0 on the reformatting of international trade on the Trade 4.0 model is substantiated, and the role of the government in these processes is determined. It has been proven that the emergence of e-commerce retail logistics (e-logistics) is a consequence of the digitalization of international trade. Cyberattacks have been identified as key threats in the field of digital transformation of international trade and logistics during hybrid wars.

Published: October 2024

W artykule dokonano rozpoznania procesu wdrożenia systemu WMS (warehouse management system – system zarządzania magazynem), jako kluczowego dla środowiska magazynowego, na przykładzie przedsiębiorstwa wdrażającego swoje rozwiązania IT w branży logistycznej. Jako cel przyjęto identyfikację skutecznej i efektywnej metodyki zarządzania projektem wdrożeniowym WMS. Do realizacji celu przyjęto metodę studium przypadku, obserwację uczestniczącą, techniki wywiadu i mapowania procesów. Wykorzystano dokumentację i raporty wdrażającego przedsiębiorstwa. Jako główny wynik badań należy odnotować to, że nie jest możliwe proste określenie minimalnych mierzalnych parametrów magazynu, przy których wdrożenie WMS jest opłacalne. Na ten aspekt wpływ ma wiele czynników, których nie można określić w prosty, parametryczny sposób: np. skomplikowanie procesów magazynowych, integracje WMS z systemami zewnętrznymi, wymagania prawne czy wymogi użytkownika systemu wobec funkcji raportowania. Przed każdym tego typu wdrożeniem należy dokonać wielowymiarowej analizy uwzględniającej determinanty wdrożenia, które mają decydujący wpływ na czas wdrożenia systemu, niezależnie od skali działalności magazynu. Jako główny wniosek należy podkreślić to że, tak jak wiele innych procesów, tak i proces wdrożeniowy systemu IT można usprawniać i optymalizować, w czym pomagają narzędzia pochodzącego z metodologii Lean Management.

Za szczegóło_x0002_we zadania badawcze przyjęto ocenę dostępności fizycznej i czasowej powiatów, z których pochodzili kandydaci na studia; identyfikację przestrzennego zróżnico_x0002_wania liczby kandydatów w zależności od miejsca zamieszkania oraz ocenę zasię_x0002_gu przestrzennego oddziaływania wydziału w podziale na kierunki i formę studiów. Materiał badawczy stanowiły zanonimizowane dane zawierające informację o kie_x0002_runku i formie studiów oraz miejscu zamieszkania kandydatów ubiegających się o przyjęcie na studia w SGGW w 2022 roku. Dostępność transportową na potrzeby badania ograniczono do dostępności drogowej – mierzonej odległością i czasem dojazdu z miejsca zamieszkania kandydata/studenta do kampusu SGGW w Warsza_x0002_wie. Kandydaci na studia koncentrowali się przede wszystkim w Warszawie oraz powiatach aglomeracji warszawskiej, przy czym zasięg oddziaływania SGGW jest największy w kierunku północno-wschodnim i południowo-wschodnim od stolicy. Liczba kandydatów maleje wraz ze zmniejszaniem się dostępności transportowej do uczelni, przy czym mimo podobnej dostępności z powiatów położonych na za_x0002_chód od Warszawy zainteresowanie studiami w SGGW było mniejsze. Zasięg prze_x0002_strzennego oddziaływania wydziału w podziale na kierunki studiów prowadzi do wniosku, iż z wyjątkiem kierunku zarządzanie mediana odległości od uczelni jest proporcjonalna do liczby kandydatów na 1 miejsce.
Ekologistyczne opakowania jako zgodna ze środowiskiem alternatywa
Authors: Ćwikowska Sabina , Hudz Viktoriia
Published: October 2024

Popularne opakowania z tworzyw sztucznych oraz innych surowców były bardzo powszechne jeszcze w latach 90. XX wieku, a dziś społeczeństwo jest świadome ich negatywnego wpływu na planetę. Plastik rozkłada się bardzo wolno, a tym samym może pozostawać w środowisku przez setki lat. Tego typu opakowania już podczas produkcji generują niebezpieczne substancje – powstają wtedy między innymi związki węgla, siarki czy metali ciężkich. W artykule podjęto problematykę szkodliwych opakowań oraz przedstawiono negatywne skutki związane z ich używaniem. Ponadto zdefiniowano podstawowe pojęcia z zakresu ekologistycznych opakowań oraz zaprezentowano bardziej przyjazne dla środowiska rozwiązanie – ekologistyczne opakowanie. W opracowaniu zawarto również informacje na temat działań podjętych przez Unię Europejską oraz inne organizacje, które wspierają zrównoważony rozwój. Podstawę analiz stanowiły wyniki badań ankietowych przeprowadzonych dotyczących świadomości ekologicznej konsumentów. Na ich podstawie zaproponowano środki, które mogłyby zachęcić klientów do podejmowania działań na rzecz ochrony środowiska.
Eit utval lærarar sine perspektiv på elevengasjement og læring i digitale kontekstar i begynnaropplæringa
Authors: Øvereng Liv Kristin Bjørlykke
Published: October 2024

Denne studien undersøker tre lærarar sine perspektiv på elevengasjement og læring når elevane brukar nettbrett i begynnaropplæringa. Det er ein kvalitativ longitudinell studie basert på individuelle intervju om læring i digitale kontekstar på to målepunkt over ein periode på to år. I det første intervjuet er det nytta lydopptak, medan det i det andre, to år seinare, er det nytta videostimulert refleksjonsdialog i tilknyting til intervjuet, med videoobservasjon frå undervisninga til den enkelte læraren. Studien er forankra i ei sosiokulturell forståing av læring, der nettbrettet er eit læringsverktøy som vert brukt i undervisninga og inn mot læringsaktivitetar. Med digitalisering av klasserommet skjer det ei endring i bruk av læringsressursar, noko som også har potensial for endring av dei andre elementa som konstituerer praksisen i klasserommet, der elevrolla er eit sentralt element. Studien viser ei endring i lærarane sine perspektiv på bruk av nettbrett i undervisninga i løpet av dei to åra. Ei endring som går frå å vektlegge tekniske sider ved nettbrettet i aktivitetar til meir læringsorientert grunngiving for bruk av nettbrett i elevar sine læringsprosessar i begynnaropplæringa. Lærarane viser ei bevisstheit om elevane sitt engasjement i ein kompleks digital undervisningssituasjon, og framhevar at bruk av nettbrett i begynnaropplæringa skal bidra i læringsprosessane til elevane.
ENGLISH ABSTRACT
Selection of Teachers’ Perspectives on Student Engagement and Learning in Digital Contexts in Beginner Education
This study examines three teachers’ perspectives on student engagement and learning when students use tablets in beginner education. It is a qualitative longitudinal study based on individual interviews about learning in digital contexts at two measure points over a period of two years. In the first interview, an audio recording was used. In the second, two years later, video-stimulated reflection dialogue with video observation of the individual teacher’s teaching was used. The study is rooted in a socio-cultural understanding of learning, where the tablet is a learning tool that is used in teaching and in learning activities. With the digitization of the classrooms, there is a change in the use of learning resources, which also has the potential to change the other elements that constitute the practice in the classrooms, where the role of the student is a central element. The study shows a change inthe teachers’ perspective on the use of tablets in teaching. A change that goes from emphasizing the technical aspects of the tablet in activities to a more learning-oriented rationale for the use of tablets in students’ learning processes in beginner education. The teachers show an awareness of the students’ involvement in a complex digital teaching situation, and emphasize the contribution of tablets use to the students’ learning processes in beginner education.

An Evidence-Based Practice Project on the Use of Ginger to Manage Primary Dysmenorrhea
Authors: Tabor Alayna , Lawrence Carol
Published: October 2024

Dysmenorrhea is a highly prevalent gynecological symptom that is widely unreported and normalized. When a woman experiences severe menstrual pain without the presence of a pelvic disorder, the pain is categorized as primary dysmenorrhea. Ginger has analgesic and anti-inflammatory properties, which when utilized for primary dysmenorrhea, shows promise in reducing pain. A literature search was conducted using several databases and hand searching to find articles that supported the following question: In adult women with primary dysmenorrhea, how does the use of ginger, compared to not using ginger, affect pain? The databases Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane Library (Cochrane Reviews), Nursing and Allied Health (ProQuest), and PubMed were included. Of the 153 articles identified, the following six articles were used for this project: two systematic reviews with meta-analyses, three randomized controlled trials, and one consensus statement. Each piece of evidence utilized the Visual Analog Scale to measure pain intensity, and all the mean pain scores were found to be significantly lower in women who used ginger supplementation. Ginger was used in different doses and for different durations in each of the pieces of evidence, however there was a significant positive relationship between ginger supplementation and reduction of pain in each article. This project identified that there is strong and compelling evidence to recommend using ginger supplementation to reduce pain.
Critical Analysis of Hominidae (Great Ape) Taxonomy
Authors: Westvold James , Gunnels Charles
Published: October 2024

This article is a critical look at the current taxonomic placement of the different species that make up Hominidae (the great ape family) to determine if any biases might be occurring in how humans are described relative to the other great apes and how taxonomic placements are understood across different disciplines. A systematic literature review was conducted to quantify the placement of the human node on the phylogenetic trees that were observed. The qualitative data includes a literature review of the philosophical/religious and linguistic perspectives and noting when the colloquial and scientific terms were used and in what context. Three taxonomic placements were presented in this thesis: the currently accepted Hominidae family, 2) the separated Hominidae-Pongidea families, and 3) an updated taxonomic placement that result from the findings in this research. The data from the quantitative and qualitative analyses were observed and the use of language were used to determine that there is a bias when researchers illustrate the taxonomic relationship of humans and other great apes. The main findings were humans, chimpanzees, bonobos, and gorillas all belong to genus Homo, and failure to group all these organisms in a single genus produces a bias within the research and leads to paraphyletic groupings where humans are perceived as separate from other great apes. This bias reinforces institutional pithecophobia in Western society that perpetuate the belief that humans are separate from other apes.
An Evidence-based Practice Project to Reduce Maternal and Newborn Pain
Authors: Stalker Kendyl , Lawrence Carol
Published: October 2024

Vaginal birth is the most common form of childbirth and can result in perineal wounds that may require repair. These repairs can be extremely painful. Once the baby is born, they will also experience painful procedures including injections and heel sticks. This evidence-based practice project was aimed at determining whether skin-to-skin contact was successful in reducing maternal and neonatal pain. A literature search was completed to address the use of skin-to-skin contact as a nonpharmacological intervention for pain relief. Thirty-one articles were found during the search and only six met the required inclusion criteria and were retained. The retained articles included four randomized controlled trials, one systematic review, and one position statement. The literature included in this evidence-based practice project determined that skin-to-skin contact was an effective intervention to relieve pain. Despite the variability in the range of dosing, anywhere from 15 minutes to over 120 minutes, the articles demonstrated that skin-to-skin contact was an efficient method for the relief of maternal and neonatal pain. The use of skin-to-skin contact was successful in reducing maternal and neonatal pain. This is a nonpharmacological intervention that may be used in conjunction with pharmacological interventions to relieve pain.
An Evidence-Based Practice Project

Primary dysmenorrhea affects a large percentage of women of reproductive age. This evidence-based practice project aimed to explore the efficacy of vitamin D supplementation on pain associated with primary dysmenorrhea. A literature search was conducted to address how oral vitamin D supplementation compares to usual care for pain. The search resulted in 127 articles, of which six were identified to address inclusion criteria. Inclusion criteria were as follows: English language, research published in the last five years (January 2019 through June 2024), and women experiencing menstrual pain without underlying pathologic cause. The literature included in this evidence-based project indicated that a significant reduction in pain is associated with supplemental vitamin D use. Optimal dosing of 50,000 IU of vitamin D or greater per week is associated with a decrease in pain as measured by visual analog scale (VAS), verbal multidimensional scoring scale (VMS), and numeric rating scale (NRS); however, other articles used a variety of dosing. Overall, vitamin D was suggested as an alternative to manage menstrual pain. Research supported the use of vitamin D for treatment of primary dysmenorrhea.
CRITICAL DISCOURSE ANALYSIS OF SOCIO-CULTURAL CONTENT AND POST-PANDEMIC THEMES IN ENGLISH TEXTBOOKS FOR JUNIOR HIGH SCHOOL
Authors: Chandra Tan Michael , Yuliani Fitria
Published: October 2024

The post-pandemic landscape, shaped by COVID-19, has ushered in substantial socio-cultural shifts, particularly in teaching and learning practices. The transition from traditional in-person learning to rapid adoption of online methods, followed by a return to in-person learning, necessitated adjustments in educational habits. This transformation is further emphasized by the Merdeka curriculum's implementation in the Academic Year 2022/2023, influencing the approach of textbook authors. This research uses Critical Discourse Analysis (CDA) and Fairclough's three-dimensional model to scrutinize five 7th-grade English textbooks from different publishers within the Merdeka curriculum framework. The analysis explores the socio-cultural and post-pandemic content, providing nuanced insights into how these materials address challenges and transformations induced by the COVID-19 pandemic. Acknowledging the inherent connection between language and socio-cultural elements, the study examines how the textbooks balance Western influences with Indonesian socio-cultural content. Additionally, it investigates how the textbooks incorporate memories of the global pandemic, contributing to the evolving landscape of English education in Indonesia.

Women resistance to early-age marriage in Wadon Ora Didol: Critical discourse analysis
Authors: Sintya Dea Erma , Pratiwi Rhesa Zuhriya Briyan
Published: October 2024

Background: Wadon Ora Didol is a documentary film highlighting women’s resistance to the problem of early marriage. The rise of early marriage in Indramayu is a serious problem regarding the exploitation and objectification of women. This is actually related to the traditions and culture of Indramayu, thus, it is giving rise to a feminist-based resistance movement against these traditions. Purpose: This article aims to analyze and describe the resistance carried out by women against early-age marriage in the film Wadon Ora Didol through critical discourse analysis of Sara Mills. Methods: It uses a descriptive research approach, with primary data collection through documentation on selected scenes and relevant literature studies. Data findings were analyzed using theories of resistance and feminism. Results: There is women’s resistance in the film Wadon Ora Didol, which is identified through two positions: first, as the subject of resistance displayed by demonstrators and their efforts to revise laws of marriage; second, a slight object position through scenes showing the exploitation and objectification of women. Dominantly, Wadon Ora Didol proves that women are the main actors who are constructed to be able to fight, be independent, and be free to express and convey criticism of the problem of early-age marriage. This film also presents women who are responsive to caring about the fate of other women, both domestically and publicly, so that all individuals are equal and have their rights to freedom. Implications: These findings provide social criticism of the importance of women’s rights in society, as well as their struggle for existence in feminism. It is hoped that the results can provide other aspects to increase public awareness to be more responsive to social problems and exploitation of women, especially regarding early marriage.
