Mine slopes play a crucial role in ensuring the safety and sustainability of mining activities. Continuous mining operations can alter slope conditions, thereby increasing the potential for instability and slope failures. Slope stability is influenced by the balance between resisting forces and driving forces acting on the rock mass. When the resisting forces are smaller than the driving forces, the slope becomes unstable and failure may occur. Therefore, slope stability analysis is essential to prevent landslide hazards, as it directly affects occupational safety, equipment security, other assets, and overall production continuity. These conditions have encouraged PT Insani Bara Perkasa to develop a more accurate and real-time slope monitoring system. The application of radar-based monitoring was initiated using the CHCNAV PS-2000 system. This study aims to analyze the deformation behavior of mine slopes using radar technology. Data acquisition was conducted at Pit K1 Mahakam, PT Insani Bara Perkasa, covering Area 1 South, AR 2 South, AR 3 South, AR 5 South, AR 6 South, AR 7 West, AR 8 West, AR 9 South, AR 13 South, as well as TA-2, TA-3, and TA-6 areas. The study was carried out from November 2025 to December 2026. The analysis results indicate that most monitoring points are in stable conditions, with indications of a progressive phase observed in the AR 6 South area.

An essential stage in road infrastructure development is land acquisition, which frequently causes project delays due to its complex legal, social, and economic challenges. This study aims to identify the factors that hinder the land acquisition process in the Manado Outer Ring Road (MORR) 3 Phase 4 Construction Project and to assess how these constraints affect the progress of construction activities. The research was conducted using a qualitative case study approach, with data collected through field observations, document reviews, and interviews. The findings indicate that delays in land acquisition are caused by discrepancies in legal status and land ownership, differing perceptions of compensation value, insufficient public socialization, and weak institutional coordination. These issues lead to disruptions in the construction schedule and potential increases in project costs. The study demonstrates that land acquisition necessitates a more cohesive strategy, facilitated by enhanced communication and community engagement, fortified land acquisition management frameworks, and precise verification of ownership data. The results indicate that there must be broader mitigation strategies to prevent similar challenges in future infrastructure projects.

This research develops a machine learning model to classify customer loyalty using the Random Forest algorithm. Customer churn is a critical issue that reduces revenue and increases acquisition costs. A dataset of 50,000 customers from global e-commerce and subscription platforms was processed through data cleaning, imputation, outlier handling, and class balancing with SMOTE. The Random Forest model was built as a baseline and optimized with hyperparameter tuning. Evaluation using accuracy, precision, recall, and F1-score shows that the optimized model achieved 90.81% accuracy and 83.87% F1-score, outperforming previous Naïve Bayes approaches. Feature importance analysis highlights customer service interactions, lifetime value, and demographic factors as key predictors of churn. These findings demonstrate Random Forest’s effectiveness in churn prediction and provide practical insights for customer retention strategies

This study aims to analyze the underlying causes of low interest in Arabic language learning and to formulate pedagogical solutions through the integration of Contextual Teaching and Learning (CTL), Cooperative Learning, and the PAKEM (Active, Creative, Effective, and Joyful Learning) framework. Adopting a descriptive qualitative approach with a library research method, this study critically analyzes data to identify epistemological, affective, and pedagogical barriers in Arabic instruction, while exploring the potential interventions of the three aforementioned strategies.The findings indicate that the decline in student interest is primarily driven by material abstraction, language anxiety, and passive instructional methods. The integration of these three strategies offers a complementary and holistic solution: CTL addresses cognitive barriers by contextualizing material into meaningful learning experiences; Cooperative Learning mitigates affective obstacles by fostering psychological safety through peer support; and PAKEM overcomes motoric-engagement barriers by stimulating joyful, active participation. The synergy of these strategies effectively shifts the instructional paradigm from passive-instructional to active-participatory, fundamentally reconstructing and enhancing student engagement and interest in Arabic language acquisition.

Listening skills are frequently regarded as the most challenging aspect of English language acquisition due to the complexity of the cognitive processes involved. In an orphanage environment, limited access to learning resources remains a primary obstacle to the development of this competence. This community outreach initiative aims to sharpen the listening skills of children at the Bonang Orphanage in Banjarmasin through the integration of subtitled YouTube videos and interactive repetition drill techniques. The implementation method involved 20 children selected via purposive sampling, utilizing a one-group pretest-posttest design. The intervention procedure encompassed the presentation of listening strategies, interactive discussions, and structured repetition exercises designed to build phonological automaticity. Quantitative evaluation results indicated a significant improvement, with the participants' mean score rising from 82.9 on the pretest to 86.7 on the posttest, with a maximum achievement score of 94. The discussion reveals that the use of subtitles serves as a visual scaffolding mechanism that facilitates sound-to-form mapping, while repetition drills strengthen the participants' working memory. Overall, the utilization of digital media and repetitive exercises proved effective in lowering cognitive barriers and increasing the participants' active engagement in English language learning.

Storytelling has been widely recognized as an effective method for teaching English to young learners because it presents language in meaningful and engaging contexts. This study aims to explore the implementation of storytelling in teaching English to primary school students and to examine the perceived benefits and challenges from the teacher’s perspective. The study employed a qualitative descriptive research design involving one English teacher who taught Grade 6 students at SDN 261 Pinrang. The participant was selected through purposive sampling due to her experience in applying storytelling activities in English instruction at the lower primary level. Data were collected through a semi-structured interview and documentation, including lesson plans and teaching materials related to storytelling used in the classroom. The data were analyzed using descriptive qualitative analysis by identifying recurring themes related to classroom implementation, student responses, perceived benefits, and instructional challenges. The findings reveal that storytelling was mainly implemented in listening and speaking activities using simple and familiar stories, visual aids, and follow-up tasks such as comprehension questions and story retelling. According to the teacher, storytelling contributed positively to students’ listening skills, vocabulary acquisition, motivation, and confidence in using English. Students showed higher levels of attention, engagement, and willingness to participate during storytelling sessions compared to traditional teaching methods. However, several challenges were also identified, including difficulty in selecting age-appropriate and culturally relevant stories, limited instructional time, large class size, and the teacher’s need for further training in designing effective storytelling activities. Despite these challenges, the study concludes that storytelling can create a positive and supportive learning environment when it is carefully planned and supported by adequate teacher preparation. The findings highlight the importance of instructional support to maximize the effectiveness of storytelling in primary EFL classrooms.

Working memory (WM) has been extensively studied as a cognitive factor influencing second language acquisition (SLA), but many studies treat it as a static, trait-like capacity. This approach provides limited insight into how WM works across different stages of development, proficiency levels, and learning contexts. This article combines theoretical and empirical research on working memory in SLA from a dynamic and developmental perspective, analyzing how the influence of WM varies over time and interacts with other cognitive and contextual factors. Referencing Baddeley's multicomponent model, complex dynamic systems theory, and longitudinal research, this article examines evidence regarding the role of WM in various language domains, including vocabulary learning, grammar processing, and language production. It also investigates how WM works differently at various proficiency levels and developmental periods, from childhood to adulthood. Evidence suggests that WM plays a very strong role in the early stages of learning when processing is effortful and controlled, but becomes less central as linguistic knowledge becomes automated. The relationship between WM and SLA appears to be bidirectional, with sustained language learning contributing to the development of specific WM components, particularly executive control. The influence of WM varies significantly based on task characteristics, teaching context, and learner profiles. Understanding WM as a dynamic resource rather than a fixed constraint has important pedagogical implications. Instructions that manage cognitive load, provide support, and encourage metacognitive awareness can help learners with diverse cognitive profiles. A developmental approach in WM research requires longitudinal designs and task-aligned methodologies to capture changes over time, thereby advancing theory and practice in SLA.

This research aims to analyze the implementation of land acquisition policies in Sorong City from the perspective of social justice for indigenous peoples, and to evaluate the extent to which customary rights are accommodated in the development process. The research method is a mixed-methods study with an embedded design. The qualitative approach was the primary instrument, using in-depth interviews with five key speakers, including land authorities and representatives of the Malaloi Indigenous Peoples Institution (LMA). Quantitative approaches are used only in correlation analysis to reinforce qualitative findings. The study's results show a "Paradox of Justice" in Sorong City. Procedurally, the land acquisition policy has been effective in accordance with Law Number 2 of 2012, supported by a strong statistical correlation between land acquisition and social justice. However, substantively, justice for indigenous peoples has not been fully achieved because the involvement of indigenous leaders in deliberations is often considered a mere administrative formality. The highest correlation between indigenous peoples and social justice confirms that the recognition of customary rights is the main determinant of justice in public policy. The main obstacles identified include difficulties in the administrative documentation of customary lands and paradigmatic differences between the government's materialistic values and the sociocultural values of indigenous peoples. The theoretical implications of this study confirm the importance of communication factors and the disposition of implementers in the implementation of policies in customary territories. In practice, the government needs to reformulate deliberations based on local values and the structural recognition of customary rights.

Article 20 of the Personal Data Protection Law (UU PDP) normatively regulates the protection of data subjects and constitutes a key provision emphasizing the principle of consent as the legal basis for the processing of personal data for commercial purposes. This norm safeguards individual privacy rights, including the validity of explicit consent, the right to withdraw consent, and the responsibility of data controllers. Furthermore, Articles 65–70 of the UU PDP substantively regulate various forms of criminal violations in the context of personal data protection, including the acquisition, disclosure, processing, falsification, and illegal use of personal data, demonstrating the state’s commitment to providing criminal law protection against personal data breaches. This study employs doctrinal legal research with a descriptive-normative approach to address two main issues. First, it aims to examine and identify the legal protection of personal data trading under the UU PDP. Second, it seeks to analyze and identify the legal certainty of personal data trading as regulated by the UU PDP. Although Article 20 of the UU PDP is intended to provide strong protection against the commercial use of personal data, the provision still gives rise to legal uncertainty due to the lack of clear regulation of several crucial aspects. Similarly, Articles 65–70 contain significant legal uncertainties, particularly with regard to the elements of criminal offenses, forms of harm, corporate criminal liability, overlap with other regulations, and the absence of clear enforcement mechanisms and implementing institutions.  

The primary objective of this research is to enhance English academic proficiency among seventh-grade pupils at UPT SMP Negeri 4 Takalar, specifically regarding "Introduction" subject matter, through the application of the Problem-Based Learning (PBL) framework. This study was necessitated by observed deficiencies in student engagement and challenges in vocabulary acquisition, particularly concerning regular and irregular verbs, which had previously led to unsatisfactory academic performance. Utilizing a Classroom Action Research (CAR) design, the investigation was executed over two distinct cycles with a cohort of 24 students from Class VII B. Data acquisition involved the administration of performance assessments and systematic classroom observations. Subsequent analysis revealed a marked enhancement in learning achievements. During Cycle I, the mean score was recorded at 78.75, corresponding to a classical mastery rate of 37.5%. Following instructional refinements in Cycle II, the average score rose to 80.42, while the classical mastery rate increased to 50%. Moreover, observational evidence highlighted constructive behavioral shifts characterized by heightened engagement in collaborative discussions and improved oral communication confidence. Consequently, this study concludes that deploying the PBL model serves as an effective strategy for augmenting both English academic achievement and social interaction within the classroom environment.

Article 20 of the Personal Data Protection Law (PDP Law) normatively regulates the protection of data subjects and constitutes a pivotal provision that underscores the principle of consent as the legal basis for the processing of personal data for commercial purposes. This normative framework safeguards individuals’ right to privacy, encompassing the validity of explicit consent, the right to withdraw such consent, and the accountability of data controllers. In parallel, Articles 65 to 70 of the PDP Law substantively establish various categories of criminal offenses within the context of personal data protection. These include the unlawful acquisition, disclosure, processing, falsification, and utilization of personal data. Collectively, these provisions reflect the State’s commitment to ensuring criminal legal protection against violations of personal data.This research adopts a doctrinal legal methodology with a descriptive-normative approach to address two primary issues: First, to examine and identify the scope of legal protection concerning the trade of personal data under the PDP Law; and Second, to assess and determine the degree of legal certainty afforded to the trade of personal data within the framework of the PDP Law.Notwithstanding the protective intent embodied in Article 20—particularly concerning the commercial use of personal data—this provision gives rise to legal uncertainty due to the absence of comprehensive regulatory clarity on several critical aspects. Similarly, Articles 65 to 70 continue to exhibit significant legal ambiguities, particularly with respect to the constituent elements of offenses, the definition of harm, corporate liability, regulatory overlap with other legislative instruments, and the lack of clear enforcement mechanisms and implementing institutions.

This study evaluates the legal perspective concerning business competition in Indonesia regarding alleged abuse of dominant power in the competition between digital platforms TikTok Shop (including the acquisition of Tokopedia) and Shopee. The method applied is normative juridical with a case study approach, referring to Law Number 5 of 1999, particularly Articles 19–21 related to market control and Article 20 concerning below-cost selling practices. The analysis focuses on inter-platform integration, aggressive discount strategies, use of cross-platform data, as well as post-acquisition behavior that may hinder healthy competition. The assessment is conducted by considering market structure, business actors' behavior, and law enforcement efforts by the Business Competition Supervisory Commission (KPPU). Research findings indicate that although TikTok Shop has strong competitiveness following the acquisition, proving the existence of abuse of a dominant position requires meeting legal and economic provisions rigorously. Therefore, the implementation of conditional approval and remedial measures by the KPPU is considered a reasonable step to maintain a healthy business competition environment in the digital era.

The primary focus of this research is to evaluate the influence of Good Corporate Governance (GCG), profitability levels, and entity scale on the market value of coal mining companies listed on the Indonesia Stock Exchange (IDX) between 2021 and 2023. This study adopts a quantitative design by utilizing secondary data from the official IDX website, where 8 companies were selected as samples from a total population of 34 coal sub-sector companies through purposive sampling techniques. Data processing was carried out through panel data regression analysis using Eviews 12 software. The research data indicates that, independently, the implementation of good corporate governance and the level of profit acquisition do not contribute significantly to determining the value of the entity. Conversely, company size is proven to have a significant negative impact. Simultaneous testing confirms that these three independent variables collectively have a significant effect on company value. These findings indicate the need for strategies that consider factors beyond good corporate governance and profitability in efforts to increase company value, such as operational efficiency and proper asset management.

The advancement of information technology has increased young children’s exposure to digital devices, which potentially affects language development. This study aims to analyze the relationship between daily screen time duration and language development of children aged 5–6 years in Desa Mendalo Indah, Kecamatan Jambi Luar Kota, Kabupaten Muaro Jambi. This research employed a descriptive qualitative approach with a case study design. The subjects were six children aged 5–6 years who had more than two hours of daily screen time. Data were collected through observations of children’s language abilities, interviews with parents, and documentation of daily activities, and analyzed using Miles and Huberman’s (2014) interactive model, including data reduction, data display, and conclusion drawing. The results showed variations in children’s language abilities despite having relatively similar screen time durations. Children who received active parental guidance and accessed educational content demonstrated better receptive and expressive language skills, including following sequential instructions, forming simple sentences, and expressing ideas verbally. Conversely, children who used screen time passively without supervision tended to have limitations in vocabulary acquisition, concentration, and verbal interaction. These findings indicate that screen time duration alone is not the sole determinant of children’s language development; it is also influenced by the quality of parental guidance, the type of content accessed, and social interaction experiences. This study is expected to provide guidance for parents, teachers, and early childhood education practitioners in managing digital media use wisely to optimally support children’s language development.

The increasing demand for infrastructure necessitates the construction of reliable bridges with long service lives to ensure smooth mobility. This research focuses on the Griya Lingga Permai Bridge over the Asam River in Jambi City, which is scheduled for widening as part of the Asam River Revitalization program aimed at flood mitigation. Although the project faces delays due to land acquisition constraints, this postponement is leveraged as a strategic opportunity to conduct a design review of the planned bridge superstructure.The bridge is designed using a reinforced concrete "T" beam girder structure. This study aims to perform a design review of the planned superstructure. This review includes the verification of calculations, structural dimensions, and a comparison of reinforcement calculation results, which are crucial for ensuring the future safety and reliability of the bridge against design loads. To support the validation and analysis process, the research utilizes STAAD.Pro software to obtain more accurate and detailed data regarding structural capacity. The results of this study will provide solid technical recommendations for the continuation of the construction project.

Rapid technological change in the digital era has reshaped the nature of organizational innovation, requiring firms not only to innovate but also to align their innovation activities with technological developments and market dynamics, a capability referred to as Techno-Resonance Innovation Capability (TRIC). Although Knowledge Management (KM) has been widely recognized as a driver of innovation, studies that explicitly link KM to the development of techno-resonant innovation remain limited. This study aims to address this gap by systematically reviewing the literature to examine how KM contributes to innovation capability and how this relationship evolves toward TRIC through absorptive capacity. Using the systematic literature review methodology proposed by Tranfield et al., this study follows three stages planning, conducting, and reporting the review to identify, evaluate, and synthesize relevant studies on KM, absorptive capacity, innovation capability, and techno-resonance. The findings indicate that innovation capability emerges from interconnected KM processes, including knowledge acquisition, sharing, storage, and application, which form the organizational infrastructure for innovation. Absorptive capacity is identified as a key bridging mechanism that enables organizations to transform managed knowledge into innovative outcomes by enhancing their ability to acquire, assimilate, transform, and exploit technological knowledge. This study concludes that integrating KM and TRIC through absorptive capacity extends conventional innovation capability models and provides a stronger theoretical explanation of innovation in technology-driven and digitally dynamic environments.

This study aims to analyze the effectiveness of the application of direct and indirect methods in teaching English, specifically the topic of "Telling Time," at MTs Al-Amiriyyah through microteaching practice. This research employs a descriptive qualitative approach with data collection techniques including observation, interviews, and documentation. The research subjects consist of an English teacher and the students of class VIII A. The data were thematically analyzed to identify significant patterns in the teaching process. The findings indicate that the direct method is effective in building students' foundational understanding of time concepts, as it emphasizes explicit and concrete use of the target language and allows teachers to easily assess students' comprehension through drilling. On the other hand, the indirect method proved to enhance students’ ability to use English more naturally through contextual activities such as role play and daily schedule games. Moreover, students with kinesthetic learning styles responded more positively to the indirect method, as it enables them to learn through physical activity and direct participation. These findings suggest that a combination of both methods yields optimal results: the direct method is effective for the initial stage of concept acquisition, while the indirect method supports the development of communicative skills in a functional and enjoyable manner, aligning with students' characteristics.

This study aims to analyze the impact of business combinations through acquisition on the financial performance of PT Sarana Menara Nusantara Tbk. The research employs a descriptive quantitative approach, focusing on the acquiring firm in the Indonesian telecommunications infrastructure sector. The data used are secondary data obtained from the company’s annual financial statements for the period 2019–2023, sourced from the Indonesia Stock Exchange and the company’s official website. Financial performance is analyzed using Return on Assets (ROA), Return on Equity (ROE), Net Profit Margin (NPM), and Debt to Equity Ratio (DER) by comparing the periods before, during, and after the acquisition conducted in 2021. The results indicate that the acquisition exerted short-term pressure on asset efficiency and profitability, as reflected by the decline in ROA and NPM in the year of acquisition. However, in the post-acquisition period, the company demonstrated an improvement in operational performance, particularly in Net Profit Margin, suggesting that the economic benefits of the business combination gradually materialized. Meanwhile, fluctuations in ROE and DER reflect adjustments in the capital structure following the acquisition. These findings suggest that the success of an acquisition cannot be evaluated solely based on short-term financial performance but requires continuous assessment to capture its medium- and long-term effects. This study provides practical implications for management in formulating post-acquisition integration strategies and contributes empirically to the accounting and finance literature on business combinations in Indonesia.

Heritage language loss among immigrant and diaspora communities represents a critical challenge to cultural identity, intergenerational communication, and cognitive diversity. Traditional heritage language maintenance approaches face significant barriers including limited resources, lack of qualified instructors, geographic dispersion, and competing demands of dominant language acquisition. This study investigates the effectiveness of bilingual digital story applications as innovative tools for heritage language maintenance among children aged 4-12 years. Through a 24-month longitudinal mixed-methods study involving 1,843 families across eight language communities (Spanish, Mandarin, Arabic, Korean, Tagalog, Vietnamese, Hindi, and Polish), we examined language proficiency development, cultural identity formation, family engagement patterns, and app usage behaviors. Quantitative analysis of pre- and post-intervention language assessments revealed statistically significant improvements in heritage language vocabulary (effect size d=0.68), listening comprehension (d=0.54), and oral production (d=0.47) among children using bilingual story apps for at least 20 minutes daily. Qualitative findings from parent interviews and child focus groups highlighted the apps' role in making heritage language learning enjoyable, facilitating parent-child interaction, connecting children to cultural narratives, and normalizing bilingualism. However, effectiveness varied substantially based on app design features, with interactive elements, culturally authentic content, parent involvement scaffolds, and adaptive difficulty showing strongest associations with outcomes. This research demonstrates that thoughtfully designed bilingual story apps can serve as accessible, scalable tools for heritage language maintenance, though they function most effectively as complements to rather than substitutes for rich home language environments and community connections. The study contributes empirical evidence to inform app development, family language planning, and policies supporting linguistic diversity in increasingly globalized societies.
