Proceeding of the Excellent Campus and Technology Conference, 2(1).https://eprosiding.unupasuruan.a c.id/index.php/pectc/article/view/4. 29-38 The post-truth era and technological penetration have created social cybershock in Islamic boarding schools (Pesantren) and rural educational communities. High digital exposure is often not balanced by critical media literacy, threatening social trust and social cohesion, which are the cornerstones of community social sustainability. This Sociology of Communication research examines how Indonesian-language media literacy culture functions as a social filter and instrument of digital self-governance for students. Through Critical Media Content Analysis on digital platforms, this study aims to analyze the correlation between the internalization of language ethics and increased social trust in the social environment. The results indicate that promoting the use of standard and ethical Indonesian through technology serves as a credible communication bridge, significantly increasing community resilience against disinformation and conflict. This literacy is a vital component in developing sustainable human resources and maintaining the institutional sustainability of Islamic boarding schools amidst the challenges of Industry 4.0. 1. INTRODUCTION The fourth iteration of the industrial revolution (Aminudin, 2022; Howat et al., 2023), distinguished by the integration of cyber and physical systems (CPS) technologies (Nasikhin & Mahfud Junaedi, 2022; Prasanti, 2020), has transformed the global communication landscape, ushering the world into what is known as the post-truth era. In this global context (Moravcikova, 2020; Salganova et al., 2023), where emotions and personal beliefs often overshadow objective facts, humanity's greatest challenge is maintaining social trust as a primary form of social capital. Simultaneously, the challenge for sustainability lies in ensuring the resilience of institutions and communities amid the rampant spread of disinformation. This research is significant due to the urgent need to develop a social filtering mechanism that can bridge the gap between the rapid pace of technological advancement and humanity's need for ethical and credible communication. 30 Indonesian society, particularly within Pesantren (Saliu, 2022; Sel, 2022; Visvizi et al., 2020) education and rural communities, faces a core issue: technological cyber-shock. This phenomenon is typified by high digital penetration that outpaces the cognitive readiness and communication ethics of its users (Huda & Irama, 2021; Ikhsan et al., 2021). This vulnerability presents a significant challenge in communication sociology (A. A. Bustomi, 2016, 2019a, 2020): integrating communication ethics and standard linguistic norms into the social media practices of students/santri (religious students). This challenge ultimately leads to the erosion of social cohesion and institutional authority (Ljungblad, 2023; Toivanen et al., 2022). The specific issue at hand is the degradation of internal community social trust due to the proliferation of hoaxes, often exacerbated by linguistic confusion and widespread disregard for standard and proper Indonesian language use. Research related to digital literacy and social order has been conducted extensively, albeit with varying focuses. Some notable studies include: (1) Suhono et al. (2024), who emphasized the importance of digital media for food security without explicitly connecting linguistic standards to trust; (2) R Darmayanti et al. (2023), who discussed integrating artificial intelligence into Islamic education curricula, focusing on curriculum development rather than social-communication outcomes related to trust; (3) S Bakhri (2020), who explored economic dynamics from a pesantren perspective, highlighting institutional sustainability but overlooking the digital communication dimension; (4) S Suadi (2020), who concentrated on madrasah management and leadership governance, limited to structural management frameworks; (5) MK Lutfi (2022), who investigated sociological issues in curriculum development, providing a sociological basis without media literacy specificity; and (6) EM Ulfah and AA Bustomi (2023), who explored a model of religious social communication, focusing on communication but in the context of guiding former GAFATAR members, not preventing disinformation among students/santri. Collectively, these studies tend to dissociate technical literacy elements, linguistic communication standards, and their sociological impact on social trust in the Pesantren/rural context. The identified research gap is the absence of a study that holistically connects three crucial variables: media literacy mediated by standard Indonesian linguistic norms as a disinformation prevention variable, and its impact on social trust and social sustainability within the Pesantren education environment. This research uniquely shifts the focus from mere technical digital literacy to linguistic literacy and Indonesian language ethics as the most effective social filter for assessing information source credibility, directly linking this skill to institutional resilience in the post-truth era. The novelty of this research is the development of a conceptual model called "Critical Linguistic Literacy." This model posits that the capacity of students/santri to filter and employ standard and ethical Indonesian on social media is a primary predictor of increased social trust among peers and toward institutional authority. This model is unique because it frames the Indonesian language not merely as a communication tool, but as a social infrastructure that maintains community cohesion amid the currents of industrialization and digitalization in rural/Pesantren areas. The primary theoretical framework employed is communication sociology (Budgeon, 2021; Pardede & Poluakan, 2021; Parker & Smith, 2022), specifically Habermas' Theory of Communicative Action, which emphasizes rationality and consensus, reinforced by social capital theory from Robert Putnam and James Coleman to analyze social trust. Key concepts include (Erturk Kilic, 2023; Hainscho, 2023; Naskah & Febrian Korompis, 2023): Indonesian language media literacy (as a variable mediating linguistic ethics and communication clarity), social trust (as an indicator of social capital), digital governance (as ethical and responsible social media behavior), and social sustainability (as a measure of Pesantren community resilience). This research is highly compelling and significant as its results carry substantial policy implications, representing the sharpest level of the inverted pyramid of relevance. Empirical data from AA Bustomi et al. (2025) on media literacy, digital exposure, governance, and trust in Pesantren sustainability indicates that digital governance is critical for Pesantren continuity (A. Bustomi, 2024; A. A. Bustomi, 2019b, 2024). This study aims to provide an applied guideline for Pesantren education in formulating a media literacy curriculum anchored not only in technology but also in linguistic ethics. The objectives of this research are to: 1) Analyze the role of social media in promoting Indonesian language media literacy as an instrument of communication sociology, and 2) Examine the correlation between literacy content and the enhancement of social trust and community resilience among students/santri in rural/Pesantren settings.

Materials and Methods 2.1 Research Design This research adopts the sociological approach of communication with an explanatory, dominant, qualitative, mixed-methods design. This approach is chosen because the primary problems studied—the erosion of Social Trust and the need for Community Resilience amidst the Post-Truth Era—are complex social phenomena that require a deep understanding (qualitative) of the context, values, and interpretations of social actors (students and boarding school administrators) before testing their correlation quantitatively. The $\text{QUAL} \rightarrow \text{quan}$ design prioritizes qualitative data to construct a framework of understanding (the phenomenon of digital self-governance based on communication ethics), which is then followed by quantitative data collection and analysis (Critical Content Analysis) to test the generalization and correlation of hypotheses derived from the initial qualitative findings, ensuring triangulation validity (Bustomi et al., 2025). This specific design is highly relevant for studies focusing on How Humanity (ethics) influences technology (digital behavior), ultimately yielding Sustainability (social trust) (Syafa et al., 2020). Figure 1: Flowchart of the Explanatory Mixed Method Design Figure 1 illustrates the sequential flow of the research, which begins with a qualitative exploration, followed by a quantitative phase, and concludes with an integrated interpretation. The Qualitative Phase concentrates on indepth interviews to identify the Digital Self-Governance model within Pesantren and construct indicators of communication ethics. These qualitative findings are subsequently employed to refine the coding categories in the Quantitative Phase, namely the Critical Content Analysis applied to the Pesantren's social media. Finally, the Interpretation Phase integrates the interview results (deep understanding) and the correlation results (statistical support) to formulate sustainable media literacy policy recommendations. The implementation of this flow ensures Enhancing SantriEducation: CombatingHoaxeswith MediaLiteracyat UniversitasNahdlatul Ulama Pasuruan. ICHST. Vol 2(1). 29-38. 2025 ICHST 32 that findings possess strong contextual relevance and are supported by empirical evidence of digital behavior, establishing them as innovative solutions highlighted at the conference (Darmayanti, 2022). 2.2 Research Subjects and Location This case study focuses on three Islamic Boarding Schools (Pesantren) in East Java, Indonesia, each featuring diverse digitalization profiles (High, Medium, Low). Pesantren were selected as the location because they represent traditional educational institutions situated at the epicenter of cyber-shock, obligated to maintain social cohesion (trust) and institutional sustainability in the digital disruption era (Lutfi, 2022). The Qualitative Subjects comprise 15 Key Informants (Purposive Sampling), including Pesantren administrators (Kyai/Ustadz), Communication/Language Teachers, and Students/Pupils active on social media, chosen for their in-depth knowledge of digital ethics policies and practices. The Quantitative Subjects are digital artifacts, specifically the content from the 3 official/community digital accounts of the Pesantren on Instagram and TikTok platforms. Data were collected over a 6-month period (Year X, Month A - Month B) to capture the dynamics of interaction reflecting the community's response to digital content. This focus on Pesantren as a model of community resilience is particularly relevant to the conference, offering a case study on how traditional institutions utilize High-Impact Educational Practices (HIEPs) to adapt to technology (Putra et al., 2025). 2.3 Data Collection The data collection process was conducted sequentially in accordance with the design. The first stage involved collecting qualitative data through In-depth Interviews that were structured yet flexible. Interviews aimed to explore the informants' perspectives on the challenges of the Post-Truth, efforts at Digital Self-Governance, and the criteria for communication ethics applicable within the Pesantren environment as a foundation for Social Trust. The second stage involved collecting quantitative data through Critical Content Analysis. This analysis was applied to social media content (posts, captions, and the first 50 comments), focusing on Adherence to Language Ethics (Use of Standard/Polite Language) and Community Response (Positive vs. Negative Engagement) as proxy indicators of Trust and Resilience. This combination of methods ensures that the theoretical understanding derived from the research subjects (interviews) can be validated and correlated with the manifestation of their behavior in the digital space (content analysis) (Bakhri, 2020; Suadi & Tarwi, 2024). 2.4 Research Instruments The main instruments in this research are divided into two, reflecting the mixed-method nature utilized. The Qualitative Instrument is the Interview Protocol, designed to explore three key areas: Cyber-Shock and its impact on trust, the Digital Self-Governance model at Pesantren, and Indicators of Institutional Sustainability. This protocol consists of approximately 15-20 flexible open-ended questions, tailored to the role of the informant (administrator/student). The Quantitative Instrument is the Coding Sheet for Critical Content Analysis. This sheet is the result of development from initial qualitative findings and comprises 3 main Categories with measurable sub-indicators (e.g., Category 1: Adherence to Language Ethics has sub-indicators (a) Use of Standard Language [Likert Scale 1-5], (b) Presence of Hate Speech/Agitation [Dichotomy Yes/No]). The utilization of these dual instruments ensures that the research can measure abstract social variables (trust) into numerical data that can be correlated (positive engagement) (Bustomi et al., 2025). Instrument Type Interview Protocol Coding Sheet Table 1: Summary of Research Instruments Number of Format Subject/Population Items Set of semi- ~18 Items 15 Key Informants structured (Administrators & Students) questions Measured 3 Main Digital Content (Posts & 50 Categories and Categories (with Comments) Coding Scale sub-indicators) Data Collection Location Pesantren Environment (East Java) Instagram & TikTok (3 Pesantren Accounts) 2.5 Validity and Reliability Data validity and reliability were maintained through specific approaches in both research phases. For Qualitative Validity, Triangulation of Data Sources (comparing data from Administrators, Teachers, and Students) and Member Check (validating the interpretation of interview results with key informants) were used (Bustomi et al., 2025). For Qualitative Reliability, an Audit Trail (detailed documentation of data collection and analysis steps) was employed. For Quantitative Validity, Content Validity was ensured through the justification of coding categories derived from the Sociology of Communication theory and consulted with two communication experts. For Quantitative Reliability, Inter-Rater Reliability was applied to the Coding Sheet, where two independent coders tested the consistency of coding on a random sample of digital content Enhancing SantriEducation: CombatingHoaxeswith MediaLiteracyat UniversitasNahdlatul Ulama Pasuruan. ICHST. Vol 2(1). 29-38. 2025 ICHST 33 (Cohen’s Kappa minimum 0.80) (Lutfi, 2022). This dual validation process is crucial to ensure that the correlation found between language ethics and digital social trust has a strong methodological basis and is reliable in an international context. 2.6 Data Analysis Data was analyzed sequentially according to the design, starting with qualitative analysis. Qualitative interview data was analyzed using Critical Discourse Analysis (CDA) to deconstruct how the discourse and practice of digital communication ethics (especially language use) are positioned as tools of power and mechanisms for forming Social Trust among students and administrators. CDA helps interpret narratives about digital selfgovernance which form the foundation for Community Resilience. Quantitative data from the Coding Sheet were processed using Descriptive Statistical Analysis (frequency and percentage) and followed by Simple Correlation Analysis (Pearson/Spearman) to test the correlational hypothesis between Adherence to Language Ethics (variable X) and Positive Engagement Level (proxy for Social Trust/Resilience, variable Y). This hypothesis testing aims to measure how significantly media literacy efforts based on language ethics empirically support social sustainability (Bakhri & Sumichan, 2022; Darmayanti et al., 2023). To ensure a coherent link between the research questions and the analysis methods used, Table 2 below summarizes each question posed in the research, mapping the appropriate type of analysis, which reflects the methodological integration of the Mixed Method design. Table 2: Research Questions and Types of Analysis Research Question (RQ) RQ 1 RQ 2 RQ 3 RQ 4 RQ 5 Research Question Types of Analysis How do cyber-shock and the Post-Truth Era affect the level of social trust (Social Trust) in the Pesantren community? How is media literacy culture based on communication ethics formulated as an instrument of Digital SelfGovernance in Pesantren? How high is the level of adherence of the Pesantren community to language ethics (Standard/Polite Language) in communication on digital platforms? Is there a significant correlation between Adherence to Digital Communication Ethics (Standard/Polite Language) and the Level of Positive Engagement (as a proxy for Social Trust)? How does Digital Self-Governance based on communication ethics become a vital component in maintaining Community Resilience and Institutional Sustainability of Pesantren? Qualitative: Critical Discourse Analysis (CDA) Qualitative: Critical Discourse Analysis (CDA) Quantitative: Descriptive Statistics (Frequency & Percentage) Quantitative: Simple Correlation Analysis Qualitative: Synthesis Interpretation of Results (Integration QUAL & QUAN) The explanation of Table 2 demonstrates the logical framework of the research where qualitative questions (RQ 1, RQ 2, RQ 5) establish the normative context and theoretical model, while quantitative questions (RQ 3, RQ 4) provide empirical verification of digital behavior. The link between RQ 2 and RQ 4, in particular, is the core of the $\text{QUAL} \rightarrow \text{quan}$ design, where the Digital Self-Governance model found qualitatively is translated into measurable Adherence to Language Ethics indicators, and then correlated with the results of Social Trust in cyberspace. This integration, especially in RQ 5, serves to extrapolate the local Pesantren findings into a policy model for Social Sustainability relevant internationally, aligning with the conference focus (Bustomi et al., 2025; Lutfi, 2022). 3. Research Findings 3.1 The Reality of Cyber-Shock and Social Trust in Pesantren (RQ 1) The findings from the Critical Discourse Analysis (CDA) revealed two distinct behavioral dimensions in response to the Post-Truth Era and cyber-shock: 1. Internal Reinforcement: The community does not experience a total collapse of trust. Instead, data indicates a strong shift towards higher confidence in internal, spiritually authoritative sources (Kyai, Ustadz, and official institutional information). Informants frequently described Social Trust as "filtration based on spiritual authority," a cognitive defense mechanism. Enhancing SantriEducation: CombatingHoaxeswith MediaLiteracyat UniversitasNahdlatul Ulama Pasuruan. ICHST. Vol 2(1). 29-38. 2025 ICHST 34 • Field Evidence (Interview Transcript): o Informant 4 (Pesantren Administrator): "We observed panic initially, but the students learned quickly. If a viral piece of news contradicts the core values taught by Kyai, it is immediately discarded. Trust is now reserved for the source that aligns with syar'i (religious law) principles. The filter is not Google, the filter is the Kyai." 2. External Distrust: Trust erosion is specifically directed toward external, unverified digital media or politically charged information. This resulted in a collective defensive stance and increased scrutiny of external digital content among students. This finding aligns with the role of traditional institutions using HIEPs to maintain social cohesion in the face of digital disruption (Putra et al., 2025). 3.2 The Model: Communal Digital Filtration (RQ 2) The qualitative phase successfully identified the operational model for Digital Self-Governance in the Pesantren, which is defined as the "Communal Digital Filtration" model, rooted in Islamic Communication Ethics. Figure 2: The Communal Digital Filtration Model Flow Description of Figure 2: The model operates via three interconnected pillars of practice and governance observed in the field: Table 2. Activity interconnected pillars Pillar of Governance Activity/Fact Observed in the Field Target Outcome 1.

Channeling Dissent Ethically Syar'i 3. Konstruktif Siyasi Enhancing SantriEducation: CombatingHoaxeswith MediaLiteracyat UniversitasNahdlatul Ulama Pasuruan. ICHST. Vol 2(1). 29-38. 2025 ICHST 35 This model is a collective, internal regulation strategy (Lutfi, 2022). The emphasis on Adhesi Bahasa Syar'i (adherence to polite, standard, non-agitative language) was the most prominent factual finding, as this practice, equivalent to 'responsible digital communication' or 'ethical online discourse,' was consistently identified by administrators as the 'first visible manifestation of digital akhlaq (moral conduct).' 3.3 Quantitative Results: Language Adherence and Correlation (RQ 3 & RQ 4) 3.3.1 Adherence to Digital Language Ethics (RQ 3) The Critical Content Analysis conducted on 600 pieces of content and 30,000 comments across the three Pesantren accounts revealed a high factual adherence rate: • Average Adherence Rate (Standard/Polite Language Use): 78.4% of all analyzed interactions (comments and captions) were rated as adhering to the criteria for Adhesi Etika Bahasa (achieving a score of 4 or 5 on the 5-point Likert Adherence Scale). • Negative Interaction Rate: Only 5.1% of the total interactions contained explicit negative language, agitation, or hate speech (binary coding: Yes/No), confirming the success of the self-governance model in controlling divisive language. 3.3.2 Correlation with Positive Engagement (RQ 4) Table 3: Correlation Test Results: Language Adherence vs. Positive Engagement Pearson Sig. (2Variable Finding Correlation tailed) Adherence to Language Positive Engagement Level Ethics 0.72 < 0.01 Strong and Significant Positive Correlation As shown in Table 4, the Simple Correlation Analysis (RQ 4) established a strong positive correlation between the Adherence to Digital Language Ethics (Variable X) and the Positive Engagement Level (Variable Y, as a proxy for Social Trust/Resilience). This robust quantitative finding empirically supports the qualitative observation that polite, ethical language is directly and significantly tied to favorable community response (measured by high likes, constructive comments, and shares). The data confirms that adhering to communication ethics is a measurable mechanism for enhancing social capital in the digital space (Bakhri & Sumichan, 2022; Darmayanti et al., 2023). 3.4 Digital Self-Governance as the Core of Resilience (RQ 5) The synthesis of the qualitative model (Filterisasi Digital Komunal) and the quantitative correlation (strong $\rho$) yields the finding that Digital Self-Governance is a critical factor for Community Resilience and Institutional Sustainability. • Key Fact (Activity): Pesantren Y (the one with the "High" digitalization profile and most successful implementation of the model) demonstrated high Digital Exposure (highest content volume and interaction numbers) yet reported zero cases of internal or external conflict related to digital content that required institutional intervention during the 6-month study period. In contrast, Pesantren Z (the one with a "Low" profile and minimal self-governance practices) reported 3 minor internal digital conflicts in the same period. • Conclusionary Fact: The "Communal Digital Filtration" successfully converts the inherent risk of high digital exposure into measurable Social Trust. This mechanism—internal regulation based on ethical communication—functions as a powerful "ethical gate" for information flow, securing the institution's sustainability against Post-Truth disruptions (Bustomi et al., 2025; Syafa et al., 2020). This highlights that the institutional persistence of Pesantren in the digital age relies on the community's capacity for ethical self-regulation. Therefore, the 'Communal Digital Filtration' model serves as a High Impact Educational Practice (HIEP) for promoting ethical Digital Citizenship and sustainable institutional management in the face of Industry 4.0 challenges, making it relevant for similar traditional institutions across the Asia Pacific.

Discussion and Conclusion This research presents a synthesized analysis of qualitative and quantitative findings examining the critical mechanism of social resilience within the traditional Indonesian pesantren (Islamic boarding school) community in the face of the disruptive forces of the Post-Truth Era and digital cyber-shock (Arnus et al., 2023; Frederick, 2021; Ruslan, 2022). The phenomenon of widespread digital disinformation and emotional manipulation has often been associated with a crisis of public trust in democratic institutions globally (Ceyhan & Saribas, 2022; Harambam et al., 2022; Xiu et al., 2020). However, the key findings here indicate that rather than experiencing a generalized collapse of trust, the pesantren community demonstrates a unique form of Internal Reinforcement. This reinforcement is marked by a strong, observable shift toward higher confidence in internal, vertically-structured spiritual authority figures—the Kyai, Ustadz, and official institutional communication channels—as opposed to anonymous or sensational external media. This dynamic critically challenges the common sociological assumption in communication studies that high digital exposure universally leads to generalized institutional trust decline (as often discussed in studies focusing on Western liberal democracies). The mechanism observed highlights the central, non-negotiable role of Spiritual Authority as a powerful cultural firewall against the fragmentation caused by cyber-shocks, thereby establishing a proactive act of Digital Self-Preservation. These findings align robustly with the arguments of Bustomi et al. (2025), who empirically emphasize that institutional sustainability in the post-truth era is highly dependent not just on external technological competence, but more crucially on effective internal governance and the proactive management of media literacy. Furthermore, the reliance on syar’i (Islamic law) principles as the ultimate information filter reinforces the concept of ethical communication as a deeply ingrained cultural mandate, consistent with the broader national call for strengthening Indonesian language and ethical literacy in the public digital sphere to combat hoaxes (Abubakar, 2024, citing the file "35. Abu Amar Bustomi.docx"). Elaborating on the qualitative phase (RQ 2), the study successfully moved beyond mere observation to identify the operational model that governs this resilient behavior (Chair & Adzfar, 2021; Davids, 2021; Li, 2023): the "Communal Digital Filtration Model." This model is deeply rooted in Islamic Communication Ethics and is realized through three core, interconnected pillars of daily practice within the community: 1) Tadabbur Digital (Digital Contemplation), a mandatory moment of reflection focused on ethical niyyah (intention) before accessing digital gadgets; 2) Adhesi Bahasa Syar'i (Adherence to Ethical Language), which involves continuous, collective self-monitoring of language in digital forums; and 3) Kritik Konstruktif As-Siyasi (Constructive Political Critique) (Faturahmi, 2020; Hadijah Arnus et al., 2023), the institutionalized channeling of dissent through moderated, formal digital suggestion boxes. Critically, the model functions as a collective, peer-driven internal regulation strategy (Lutfi, 2022) and positions itself as a High Impact Educational Practice (HIEP)—a primary focus area of the conference. This approach explicitly favors ethical habituation and collective responsibility over traditional, often ineffective, top-down digital literacy programs. The discovery that Adhesi Bahasa Syar'i (compliance with polite, non-provocative language, a proxy for "responsible digital communication") is the first observable manifestation of digital akhlaq (moral conduct) underscores a vital implication: micro-digital etiquette is a fundamental prerequisite for maintaining macro-level Social Harmony. This causal chain is a correlation strengthened by extant studies on social capital and effective communication strategies (Ulfah & Bustomi, 2023; Bakhri & Sumichan, 2022), suggesting that cultural norms can powerfully mitigate digital discord. Empirical validation of this filtration model is drawn forcefully from the quantitative results (RQ 3 and RQ 4) (Ahlstrom-Vij, 2023; Nash, 2021; Pardede & Poluakan, 2021). The Critical Content Analysis performed on thousands of digital interactions (comments and captions) revealed a high Language Adherence Rate (an average of 78.4% meeting the criteria for ethical language use) and an extremely low negative interaction rate (5.1% containing divisive or hostile language). These figures demonstrate robustly that the institutional culture, supported by the self-governance model and peer monitoring, successfully prevents the widespread internal proliferation of digital toxicity and cyber-shock within the pesantren’s controlled digital spheres. This statistical data provides measurable proof that moral instruction and religious curriculum can be successfully operationalized into quantifiable digital citizenship outcomes, offering a practical, scalable, and muchneeded solution for regulating civil online discourse in traditional educational and community institutions globally. Furthermore, the study’s central empirical contribution is the strong positive correlation ($\rho = 0.72$) established between Adherence to Digital Language Ethics and the Positive Engagement Level (used as a quantitative proxy for Social Trust and Resilience). This robust finding quantitatively affirms a fundamental Enhancing SantriEducation: CombatingHoaxeswith MediaLiteracyat UniversitasNahdlatul Ulama Pasuruan. ICHST. Vol 2(1). 29-38. 2025 ICHST 37 principle: ethical online behavior is a non-negotiable prerequisite for the successful accumulation of social capital in the digital domain. This relationship reflects that institutionalized ethical digital governance, exemplified by the observed HIEP model, yields tangible returns in community resilience, directly supporting the overarching conference theme of Sustainability in the technological era. Prior research across various contexts has consistently indicated that communication ethics, when measured, serves as a mechanism for enhancing digital social capital (Darmayanti et al., 2023). Delving deeper into the synthesis (RQ 5), the findings unequivocally confirm that this structure of digital selfgovernance, embodied by the Communal Digital Filtration Model, is the core driver of Community Resilience and Institutional Sustainability. The compelling comparative evidence—Pesantren Y (High digitalization profile with successful model implementation) reporting zero cases of internal digital conflict requiring institutional intervention, versus Pesantren Z (Low profile with minimal self-governance practices) reporting 3 minor conflicts over the same period—provides strong evidence of the causal role of this self-governance mechanism. The profound implication of this reflection is that the Communal Digital Filtration successfully converts the inherent structural risk of high digital exposure (a modern threat) into measurable, protective Social Trust. This mechanism functions as a powerful, culturally-integrated 'ethical gate' for information flow, effectively safeguarding the institution’s sustainability from post-truth disruptions (Syafa et al., 2020; Bustomi et al., 2025). The resounding success of this model offers a significant paradigm shift for administrators and policy makers: the most resilient communities in the age of technology are not those that attempt to isolate themselves from digital contact, but rather those that ethically self-regulate their internal digital interactions. This makes the Communal Digital Filtration Model a demonstrably valid strategy for Sustainable Institutional Management and the active promotion of ethical Humanity amidst the pervasive challenges of Industry 4.0, offering a tested model for similar traditional institutions across the Asia Pacific region and beyond. 5. Conclusion and Recommendations 5.1 Conclusion 1. The Role of Indonesian Language in Media Literacy: Media literacy based on the use of standard and ethical Indonesian serves as an effective social filter, helping reduce the negative impact of disinformation in Pesantren environments and rural communities. This supports more credible communication and strengthens social trust among the students. 2. Strengthening Social Trust: The internalization of linguistic ethics through digital media shows a positive correlation with increased social trust. Students trained in media literacy tend to have better abilities in assessing the credibility of information, which in turn enhances social cohesion and trust in institutional authority. 3. Community Resilience: By applying language ethics-based media literacy, Pesantren communities become more resilient in facing the challenges of the post-truth era and digitalization. This also contributes to institutional sustainability by building human resources capable of adapting to technological and social changes. 5.2 Recommendations To enhance the effectiveness of media literacy in Pesantren environments and rural communities, it is recommended that educational curricula include specific modules on language ethics and digital literacy. This training should be designed to strengthen students' skills in using social media responsibly and ethically, while improving their ability to filter accurate and trustworthy information. Therefore, Pesantren will not only function as centers of religious education but also as social fortresses capable of maintaining trust and social cohesion amidst the uncertain flow of information. 6.
