Breast tumors are classified into two types, namely benign and malignant tumors, the latter commonly referred to as breast cancer. Breast cancer is one of the major health problems affecting women worldwide, including in Indonesia. According to WHO data in 2022, there were 2.3 million breast cancer cases with 685,000 deaths globally, while in Indonesia, 396,914 cases and 234,511 deaths were reported. The high incidence rate is exacerbated by low public awareness in recognizing early symptoms and performing early detection, resulting in 60–70% of cases being diagnosed at an advanced stage, supported by findings that 65.6% of female students still have a low level of knowledge. Female students were selected as research subjects because they are in a vulnerable reproductive age group and have an important role in increasing awareness of early detection, yet they still have limited knowledge. Based on this, this study aims to design a web-based early detection system for breast tumor risk using the Forward Chaining method, which functions as a tool to identify early symptoms, assess risk levels, and provide information on prevention and initial management. This study employed the method with the Expert System Development Life Cycle (ESDLC) model, consisting of the stages of assessment, knowledge acquisition, design, testing, and documentation, along with the Forward Chaining inference method.

Mergers and acquisitions have served as a primary strategy for global banking consolidation over the past three decades, including in Indonesia, which is currently undergoing one of its most massive consolidation waves—one notable example being the emergence of Bank Syariah Indonesia. This article aims to provide a narrative review of the literature on the operational impacts of mergers on bank performance, with a particular focus on implications for the Indonesian context. Based on a systematic search of the Scopus database, 52 peer-reviewed articles published between 2000 and 2025 were analyzed using a narrative thematic synthesis approach. Five main themes were identified: cost efficiency, service quality, risk management, human resource and cultural integration, and information systems and technology integration. The key findings indicate that although 73.1% of studies report post-merger improvements in cost efficiency, these benefits are highly contingent upon the quality of post-merger integration especially in the areas of human resources, organizational culture, and information technology with IT integration failure rates reaching as high as 75%. Domestic mergers consistently achieve efficiency gains more rapidly than cross-border mergers, whereas risk implications depend heavily on the type of merger and the quality of integration. Policy implications include the need for the Financial Services Authority (Otoritas Jasa Keuangan) to monitor post-merger integration quality, provide integration guidelines for smaller banks, take into account the specific characteristics of Islamic banks, and ensure a streamlined, non-burdensome licensing process. Further research particularly empirical studies on banking mergers in Indonesia—is urgently needed to test the generalizability of global findings to the local context.

This study aims to design and develop an Augmented Reality (AR)-based application for real-time data monitoring of an automatic weather station at PT. XYZ. The system was developed using a prototyping method, involving five key stages: sensor data acquisition via CBOX devices and the Modbus RTU protocol, data transmission through a Flask-based Web API, storage in a MySQL database, QR code-based target image creation using the Vuforia Engine, and a 3D visualization interface developed with Unity integrated with the Vuforia SDK on Android devices. The system successfully received and stored weather data—such as temperature, humidity, and wind speed—into the MySQL database. The AR application also displayed a stable 3D interface panel over QR code markers, providing real-time data updates through an HTTP-based mechanism. This research demonstrates the successful integration of SCADA, Flask, MySQL, and Unity, enhancing both the functionality and commercial appeal of PT. XYZ’s weather station products. Future research should focus on field testing, cloud network integration, and device compatibility.

Infrastructure development as a National Strategic Project (NSP), such as the Yogyakarta-Bawen Toll Road, aims to improve public welfare but often faces a crucial issue in the land acquisition process, namely the determination of compensation. This research examines the application of substantive justice, which focuses not only on procedural compliance (procedural justice) but also on the fairness and adequacy of the final outcome for the entitled parties. Using a juridical-empirical approach, this article analyzes two main problems: first, how substantive justice is realized in the deliberation stage of determining compensation and what factors cause disagreement from residents. Second, how the overall stages of land acquisition affect the achievement of substantive justice and the obstacles encountered. The analysis shows that although the land acquisition stages have procedurally followed Law No. 2 of 2012, the achievement of substantive justice is still hindered. Factors such as the appraisal of compensation which is deemed not to cover non-physical losses, lack of transparency, and an imbalanced bargaining position in deliberations are the main causes of disagreement. Obstacles in the planning, socialization, and payment stages also impede the realization of a complete sense of justice for the affected communities. This study is expected to contribute to the development of land acquisition policies that prioritize fairness, transparency, and the protection of the rights of affected communities.

The coal mining industry requires accurate stockpile volume measurements for inventory and production reporting. Conventional methods have limitations in accuracy, efficiency, and safety. This study compares the accuracy and efficiency of coal stockpile volume measurements using a Terrestrial Laser Scanner (TLS) Leica MS60 and an Unmanned Aerial Vehicle (UAV) DJI Matrice 4E, validated by the ASTM D6172-98 standard. Conducted on five Run of Mine (ROM) coal stockpiles covering 13,500 m² at PT XYZ, Lahat, South Sumatra, the TLS method used 43 scan positions, while the UAV employed 430 aerial images with specific flight parameters. Data were processed using Leica Infinity, Surpac, and Agisoft Metashape. The results showed volumes of 94,076 m³ (TLS) and 94,965 m³ (UAV), with a difference of 889 m³ (0.95%). Volume deviations ranged from 0.48% to 1.89%, with an average of 1.42%, all within the ASTM tolerance (<2%). Time efficiency analysis revealed that the UAV method required 200 minutes (3.33 hours), saving 63.3% (approximately 6.17 hours) compared to the TLS method (570 minutes). The largest efficiency gain occurred during field data acquisition, with an 85% reduction in time. This study confirms UAV photogrammetry as a valid, accurate, and efficient alternative for coal stockpile volume measurement in mining.

This study investigates the role of Google Translate in supporting English vocabulary learning among junior high school students in the digital era. The research employs a qualitative approach involving seventh-grade students at SMP Negeri 19 Medan. Data were collected through pre-test and post-test, classroom observation, interviews, and documentation. The findings reveal that Google Translate significantly helps students understand vocabulary more quickly, improves their learning efficiency, and increases their confidence in completing English tasks. Students also demonstrate greater autonomy in exploring new vocabulary independently. However, the study also identifies challenges, particularly students’ tendency to rely excessively on direct translation without fully understanding context, which may lead to superficial learning. Therefore, teacher guidance is essential to ensure the effective and critical use of this tool. The study concludes that Google Translate can serve as a valuable learning resource when integrated appropriately into classroom instruction. The findings contribute to the development of technology-enhanced language learning and provide practical implications for teachers in utilizing digital tools effectively.

Agrarian conflict is a common issue in development processes, particularly when changes in land ownership or control involve various interests. This study aims to analyze the dynamics of agrarian conflict in the coastal area of ​​Atapupu Beach, Jenilu Village, Kakuluk Mesak District, Belu Regency, triggered by the land acquisition process by the Defense University (UNHAN). The study used a qualitative approach with a case study method to understand the social conditions developing in the community. Data were obtained through in-depth interviews, field observations, and documentation. The results indicate that the conflict arose due to changes in community access to coastal areas previously used for economic activity. The presence of UNHAN has restricted community activities in the Fish Auction Place (TPI) area, previously a center for fishing activities. This situation has given rise to social tensions between the community and the area management. This study emphasizes that coastal area management needs to consider local community interests through a dialogical and participatory approach to minimize agrarian conflict.

Coal stockpile volume measurement is an essential part of mining production control. This study aims to evaluate the calculation of coal stockpile volume using a Total Station (TS) at PT. Bukit Baiduri Energi, Kutai Kartanegara Regency, East Kalimantan Province, and to assess the accuracy and effectiveness of this method in operational activities. Data acquisition was carried out through direct field measurements using a Total Station with a detailed surface point survey method. The collected data were processed using Minescape 5.7 software to generate a triangulated surface model, and the volume was calculated using the Cut and Fill method. The results show that the Total Station method produced a stockpile volume of 21,069.15 m³ with a high level of accuracy due to direct field measurement. This method provides advantages in elevation data accuracy; however, it requires relatively more time and manpower during the data acquisition process. Based on these findings, the use of Total Station is recommended for stockpile volume calculations that require high accuracy, particularly for production evaluation and coal reserve reporting.

The development of Pantai Indah Kapuk 2 (PIK 2) presents serious issues, including eviction, the loss of traditional livelihoods, and the marginalization of local communities within a modernization agenda that disregards social justice and sustainability. This research questions the extent to which the dominant modernization bias influences the socio-economic conditions of the surrounding community, as well as how public participation practices are implemented in the planning and execution of the project. The PIK 2 project has led to social inequality, the deprivation of rights, and environmental degradation, illustrating a pattern of systemic exploitation of coastal communities through the economic and political power of development elites. The dominant development theory framework proposed by Melkote and Steeves is used to examine modernization bias, supplemented by Islamic concepts such as mustadh’afin and ghasab to strengthen the social justice perspective. In this study, the author employs a qualitative case study approach, utilizing in-depth interviews, field observations, and documentation involving affected residents, community leaders, and policymakers. The results of the analysis indicate very low levels of public participation, instances of intimidation during land acquisition, and a significant loss of access to employment and basic facilities for the community. The conclusion of this research emphasizes the need for policy reform to ensure that development is more transparent, participatory, and equitable, in order to protect the rights of local communities from dominant and exploitative development patterns.

English learning at the elementary school level plays an important role in developing students’ early language competence, particularly in listening skills as the foundation for other language abilities. However, many learning processes still rely on conventional teaching methods that do not fully accommodate the developmental characteristics of young learners, resulting in limited engagement and listening comprehension. Therefore, this study aims to analyze the role of storytelling in improving English listening skills among elementary school students and to identify effective implementation strategies in classroom learning. This research employs a library research method by reviewing and analyzing various relevant literature sources, including books, scientific journals, and previous research findings related to storytelling in English language learning. The analysis shows that storytelling contributes significantly to improving students’ listening comprehension, vocabulary acquisition, attention, and learning motivation. Through structured narratives, expressive delivery, and the support of visual media, storytelling creates a contextual and meaningful learning environment that helps students understand spoken English more effectively. The findings also indicate that the effectiveness of storytelling is closely related to the developmental characteristics of elementary school students who learn better through concrete, imaginative, and engaging experiences. Furthermore, the implementation of storytelling through systematic stages pre-listening, while-listening, and post-listening can enhance students participation and comprehension during the learning process. In conclusion, storytelling can be considered an effective instructional strategy for improving English listening skills among elementary school students while also supporting vocabulary development and creating an engaging learning atmosphere.

Land acquisition for public purposes is intended to ensure land availability for development while safeguarding the rights of affected parties through fair and equitable compensation as regulated under Law Number 2 of 2012 and its implementing regulations. However, disputes over land ownership often prevent direct payment of compensation, thereby necessitating the use of a consignment mechanism through the court. This study examines the implementation of consignment for disputed land and analyzes the legal standing and fulfillment of rights of both the prevailing and losing parties in the land acquisition process for the development and revitalization of Balohan Port, Sabang. The research addresses the problem of how compensation is secured and distributed when ownership remains contested, and whether the mechanism ensures legal certainty and justice for all parties involved. Employing an empirical legal method with a qualitative approach, data were collected through interviews and document analysis. The findings reveal that consignment functions as a legal instrument to safeguard and temporarily suspend compensation payment until a final judicial determination is reached. Supreme Court Decision Number 1675 K/Pdt/2021 affirms that the prevailing party is entitled to full land compensation as recognition of proprietary rights, while building compensation may be relinquished through a peace agreement and social compensation partially allocated. Conversely, the losing party forfeits land rights but retains full building compensation and partial social compensation based on the settlement deed. The study concludes that dispute resolution in land acquisition extends beyond final court judgments and requires non-litigation mechanisms to ensure proportional distribution of rights, thereby reinforcing legal certainty, preventing further disputes, and ensuring equitable protection in public interest development.

Education involves acquiring knowledge and skills, with English learning being a skill-based process that requires consistent and engaging practice. In the digital era, mobile applications have emerged as effective tools to overcome traditional limitations in language learning. This study investigates the effectiveness of the Duolingo application in enhancing English vocabulary among university students. A pre-experimental one-group pretest-posttest design was employed involving 40 first-semester Pharmacy students at Anwar Medika University. Participants engaged in daily Duolingo practice (20 XP per day) for 30 consecutive days. Data were collected through vocabulary pretest and posttest as well as a Likert-scale questionnaire. Quantitative analysis revealed a significant improvement in vocabulary scores, with the mean score increasing from 57.25 in the pretest to 81.70 in the posttest. Questionnaire results indicated high student motivation, positive perceptions of the app’s usefulness and ease of use, and minimal perceived disadvantages. The findings suggest that daily Duolingo practice is an effective, engaging, and accessible method for boosting English vocabulary acquisition. This study provides practical insights for educators seeking innovative technology-integrated approaches to language teaching.

Vocabulary acquisition is a fundamental component of English language learning because it enables students to comprehend texts and develop broader communication skills. In elementary school contexts, however, vocabulary instruction is frequently delivered through traditional teaching practices that are not closely related to students’ real-life experiences. As a result, students often face difficulties in understanding and retaining new vocabulary. One potential approach to address this issue is the integration of local wisdom into learning activities so that the materials become more contextual and meaningful for learners. Therefore, this study aims to examine how the incorporation of local cultural elements can support vocabulary development among elementary school students. This research employed a descriptive qualitative design using a library research method. The data were gathered from various academic sources, including national and international journal articles, scholarly books, and conference proceedings that discuss English language learning, vocabulary development, and the integration of local wisdom in educational practices. The collected data were analyzed through thematic analysis by identifying, comparing, and synthesizing relevant findings from previous studies. The results indicate that the use of local cultural content, such as folklore, traditional practices, and community-based contexts, can significantly support students in understanding and remembering new vocabulary items. Learning materials that reflect students’ cultural backgrounds also contribute to higher levels of learning motivation and classroom participation. In conclusion, integrating local wisdom into English learning can create a more meaningful instructional environment and effectively support vocabulary mastery among elementary school students.

This study aims to examine the use of picture books as a visual literacy medium in teaching English at the elementary school level, particularly in the context of English as a Foreign Language (EFL). This research employed a qualitative descriptive literature review by analyzing relevant national and international journal articles published within the last five years. The findings indicate that the integration of visual and verbal elements in picture books contributes significantly to students’ language development, especially in vocabulary acquisition, reading comprehension, and meaning construction. From an affective perspective, the use of picture books enhances students’ motivation, learning interest, classroom participation, and reduces language learning anxiety. The effectiveness of visual media is theoretically supported by Dual Coding Theory, which explains that information processed through both verbal and visual channels strengthens memory retention and comprehension. However, several challenges remain, including the selection of appropriate picture books and teachers’ limited competence in visual literacy. Therefore, systematic instructional planning and professional development for teachers are essential to optimize the use of picture books in EFL classrooms at the elementary level.

Globalization and technological developments require students to have global competencies, one of which is English language skills. This study aims to examine the urgency of English learning in elementary schools (SD) in preparing students' global competencies through a literature review. The method used is a qualitative research approach with a literature study sourced from scientific journals, academic books, and relevant educational documents from 2020–2025. Data analysis was conducted using content analysis techniques through data reduction, grouping themes, and synthesis of findings. The results of the study indicate that elementary school age is the optimal phase for language acquisition, so that early English learning can improve students' communication skills, digital literacy, and cultural openness. Communicative and contextual learning has been proven effective in increasing student motivation and self-confidence. Despite challenges such as limited teacher competence and students' fear of speaking English, English learning in elementary schools remains a crucial investment in preparing a generation ready to face global demands.

This research investigates the effectiveness of digital storytelling as a supplementary tool for lexical fact retrieval and sustainable retention of EFL vocabulary among middle school learners. The research was conducted in particular Islamic School in Gresik, Indonesia. The selected participants were 38 eight-grade EFL learners, divided into experimental and control groups. Vocabulary knowledge was assessed through pre-test, immediate post-test, and delayed post-test conducted after two weeks. The independent sample t-test showed a significantly greater mean improvement in the digital storytelling (DST) group compared to the control group (MD = 8.04, p < .001). The vocabulary retention proved by the result of paired sample t-test which show consistency on the students’ delayed test result (p > .005). This study contributes to the growing literature on digital storytelling and its impact on lexical support. The method proved that DST is effective to enhance students’ vocabulary retention through related multimedia. Digital Storytelling enhance students’ focus and motivation to participate in class.

This study examines thee regulations governing the post-notification obligation for share acquisitions from the perspective of competition law in Indonesia, as well as efforts to optimise it as an effective supervisory instrument. Indonesia adopts a post-notification system as stipulated in Law No. 5 of 1999 and its implementing regulations, which require business entities to report acquisition transactions to the KPPU after the transaction has taken effect. Although this system provides flexibility for business entities, in practice there are a number of weaknesses, including its reactive nature, low levels of compliance, and limitations in the effectiveness of oversight in preventing anti-competitive effects. This study employs a normative legal method using legislative, conceptual, and comparative approaches, as well as an analysis of KPPU decisions. The research findings indicate that the post-notification system is not yet optimal in maintaining healthy business competition. Therefore, there is a need to strengthen oversight mechanisms, improve business compliance, and update legal policies to be more adaptive, including the possibility of limited integration of pre-notification elements. It is hoped that these optimisations will enhance the effectiveness of acquisition control and prevent monopolistic practices and unhealthy business competition in Indonesia.

Unlike Indo-European languages, Indonesian (Bahasa Indonesia) and most other Austronesian languages lack grammatical tense marking, presenting a fundamental typological difference with significant implications for linguistic theory and second language acquisition. This study investigates how Indonesian expresses temporal reference without grammatical tense, comparing it with tensed languages, and exploring the cognitive and typological implications of tenselessness. We employed a mixed-methods approach combining: corpus analysis of 5,000 Indonesian sentences; comparative linguistic analysis with English and Mandarin Chinese; psycholinguistic experiments with 200 native Indonesian speakers; and a cross-linguistic survey of 15 Austronesian languages. Results revealed that Indonesian expresses temporality primarily through lexical temporal markers (sudah, sedang, akan) in 68.3% of contexts, temporal adverbials (82.1%), and contextual inference (34.5%). Psycholinguistic experiments showed no processing disadvantage for Indonesian speakers in temporal reasoning tasks compared to English speakers. Cross-linguistic analysis confirmed that 86.7% of surveyed Austronesian languages lack grammatical tense, suggesting tenselessness represents a stable inherited feature of the family. Indonesian's tenseless system represents not a linguistic deficit but an alternative, equally sophisticated means of temporal expression. These findings challenge universal claims about tense as a necessary grammatical category and have significant implications for linguistictypology, second language pedagogy, and theories of universal grammar.

The rapid development of technology in the era of the Industrial Revolution 4.0 has driven the education sector to continuously adapt to the evolving demands of digital-based industries. One of the key technological innovations supporting this transformation is the Internet of Things (IoT), which enables data acquisition, real-time monitoring, and remote control of systems through internet networks.
