This study aims to analyze a comparison of coal stockpile volumes using the DJI Mavic 3 Pro Unmanned Aerial Vehicle (UAV) method versus the truck count method at PT. Mitra Barito. Data collection was conducted through aerial photography using a UAV at altitudes of 60 meters and 70 meters, as well as Ground Control Point (GCP) measurements using GPS. The aerial imagery data was processed using photogrammetry software to generate orthophotos and a Digital Elevation Model (DEM), followed by a geometric accuracy test based on the Geospatial Information Agency Regulation No. 6 of 2018, using the Circular Error 90% (CE90) and Linear Error 90% (LE90) parameters. The research results show that high-quality processing at an altitude of 60 meters yields a CE90 value of 2.1619 meters and an LE90 value of 4.3656 meters, thereby meeting the accuracy standards for RBI maps at a scale of 1:5,000, Class 3 for horizontal accuracy, and a scale of 1:10,000, Class 3 for vertical accuracy. Volume calculations of the stockpile using UAVs yielded a result of 22,750.900 m³, while the truck count method produced a volume of 23,503.300 m³. The volume difference between the two methods was 753.400 m³, with a deviation percentage of 3.2%. Based on the research results, the UAV method is considered capable of providing relatively accurate calculations of coal stockpile volume.

The development of digital technology has brought about significant changes in various aspects of life, including early childhood faith education. Today’s children are growing up in an environment familiar with digital media, making it necessary to adopt a catechetical approach that keeps pace with the times. This article aims to examine the use of digital catechesis as a tool for early childhood faith education. This study employs a qualitative method with a literature review approach, gathering data from books, scientific journals, research articles, Church documents, and other relevant sources. The data is analyzed using descriptive-qualitative methods to understand the benefits, challenges, and role of digital catechesis in fostering children’s faith. Research findings indicate that digital catechesis can serve as an effective, engaging, and interactive medium for helping children learn about the teachings of the faith from an early age. The use of animated videos, religious songs, educational images, and learning apps can enhance children’s interest in learning, attention, and understanding of Catholic faith values. Furthermore, digital catechesis also assists the Church, families, and schools in providing faith education that is more contextual and aligned with the world of today’s children. However, the use of digital media still requires the guidance of parents, teachers, and faith mentors so that children receive proper direction and are protected from the negative impacts of technology. Thus, digital catechesis is a relevant tool in the faith education of young children when used wisely and purposefully. The presence of digital media does not replace the role of faith educators but serves as a tool that enriches the process of proclaiming the faith in the modern era.

The dissemination of personal data through digital media has increased significantly alongside the growing use of Quick Response (QR) Codes for various purposes, such as electronic tickets, certificates, and digital identities. Conventional QR Codes are open and can be easily scanned, copied, or manipulated by unauthorized parties. The personal data referred to in this study includes sensitive information such as full name, identity number (NIK/National ID), date of birth, address, phone number, and email address. This research proposes a layered security system that combines the Advanced Encryption Standard (AES) cryptographic algorithm with steganography using the Discrete Cosine Transform (DCT) method. The process begins with encrypting personal data using AES, converting the encrypted result into a QR Code, and embedding the QR Code into a digital image using DCT, hiding it in the image’s frequency domain. The digital images used are of fixed size and formats that preserve visual quality. System evaluation is carried out by testing the visual quality of the stego image, the success rate of QR Code extraction, and the integrity of the encrypted data. The results are expected to conceal sensitive information visually while maintaining its confidentiality, with potential applications in electronic ID cards, digital certificates, e-tickets, and other confidential documents.

Gesture  recognition  technology  is  used  to  detect  movements  through  image processing,   enabling  computers  or digital devices to understand and interpret human  body  movements  as  input  or  commands.   This  technology  has  great potential  to bridge communication between the deaf community and individuals without   hearing   impairments,    enhancing  interaction  and  enriching  mutual understanding between the two.  However,  the accuracy ofgesture recognition is often  affected  by variations in the distance between hand landmarks.  Based on this problem,  this research proposes a methodfor stabilizing the measurement of distances between landmark points  in gesture recognition through a polynomial regression  approach.   Specifically,   the  distance  between  hand  landmarks  is calculated and stabilized using polynomial  regression to improve the accuracy of gesture recognition.  This method is implemented using the MediaPipeframework to detect and track hands in real-time,  and the OpenCV library to manage video. The  research  results  show  that  this  approach  can  significantly  improve  the stability  and accuracy  of gesture detection.   The developed system successfully detects gestures for  letters A  through F with a high accuracy  rate,  averaging above 98,3%.  The use ofpolynomial regression helps enhance detection accuracy by reducing noise in the landmark data.

Sign language recognition is one of the areas of image recognition and image processing technology that is developing rapidly in human-computer interaction. This technology really helps the deaf and speech impaired in communicating with non-disabled people. This research aims to examine the optimization of an object tracking system in sign language using the Gaussian Mixture Model (GMM) and Kalman Filter by including the Region of Interest (ROI). The proposed system consists of three main components, namely hand detection, object extraction, and classification. Hand detection is done using the Kalman Filter to track hand movements accurately. Next, Region of Interest (ROI) features, such as shape, direction and movement features, are extracted from the detected part of the hand. These features are fed into a Gaussian Mixture Model (GMM) classifier, which can recognize sign language based on the extracted features. With the combination of GMM and Kalman Filter in this research, it can increase accuracy in object tracking, reduce interference from the background, and ensure the tracking focus remains on important objects. The dataset used is in the form os SIBI alphabet symbols, namely A-Z with the amount of data for each class, namely 620 images. Based on the research result, model testing using GMM, Kalman Filter and ROI produces higher accuracy of 99%, while model testing using GMM and ROI produces accuracy of 90%.

This study aims to analyze the influence of a halal lifestyle on consumer preferences in selecting Sharia-compliant retail products. The study employed a Systematic Literature Review method, reviewing various empirical and conceptual studies published between 2017 and 2025. The analysis focused on the relationship between halal awareness, religiosity, ethical consumption values, and Muslim consumer behavior in making choices about Sharia-compliant retail products and services. The results indicate that a halal lifestyle is viewed not only as a form of compliance with Islamic law but also as a social identity and a modern consumption pattern that influences consumer purchasing decisions. Consumers with high levels of halal awareness and religiosity tend to have a greater preference for Sharia-compliant retail products that guarantee halal certification, quality, transparency, and ethical values ​​in their business processes. Furthermore, trust, Islamic brand image, and marketing strategies based on Islamic values ​​contribute to strengthening consumer loyalty to Sharia-compliant retail. This research provides managerial implications for Sharia-compliant retail businesses to develop innovative, educational, and tailored marketing strategies to meet the halal lifestyle needs of modern Muslims.

The rapid development of Artificial Intelligence (AI) has transformed various sectors of human life, including church ministry and religious organizational management. This study aims to analyze Christian leadership ethics in the use of AI within modern church ministry. The research employs a qualitative descriptive method through theological literature review and analysis of recent studies concerning digital technology and pastoral ministry. The findings indicate that AI provides significant benefits for church administration, digital communication, congregational data management, and online evangelism. Nevertheless, ethical challenges also emerge, such as the weakening of pastoral relationships, data privacy concerns, algorithmic bias, and the risk of dehumanization in ministry practices. From a Christian theological perspective, ministry is fundamentally relational and incarnational, reflecting the example of Jesus Christ who ministered through personal presence, compassion, and direct interaction with people. Therefore, AI should be understood as a supportive instrument rather than a substitute for spiritual authority and pastoral presence. Christian leadership in the digital age must be grounded in integrity, transparency, spiritual discernment, and respect for human dignity as the image of God (imago Dei). This study contributes to the development of ethical guidelines for churches in utilizing AI responsibly while maintaining theological integrity and Christian spiritual values.

This study aims to analyze the phenomenon of flexing on social media as a representation of social status in digital society through the perspectives of Jean Baudrillard’s simulacra theory and Erving Goffman’s self-presentation theory. The research employs a qualitative method using content analysis of social media posts, particularly on Instagram and TikTok, that display flexing practices. The research data consist of photos and videos containing symbols of luxury, such as branded goods, luxury vehicles, exclusive locations, and consumptive lifestyles. The findings reveal that flexing is not merely an act of showing off, but also a conscious self-representation strategy used to construct a particular social image. The luxury symbols displayed often do not fully reflect reality, but rather represent identity constructions that have been selectively curated and manipulated according to the desired image. From the perspective of simulacra, these representations have replaced reality itself, causing the boundary between reality and representation to become increasingly blurred. Furthermore, the phenomenon of flexing is closely related to consumer culture, the need for social recognition, and personal branding strategies in the digital era. Exposure to flexing content also encourages social comparison, which may lead to psychological pressure among audiences. Therefore, flexing can be understood as a multidimensional phenomenon reflecting changes in how individuals construct identity, perceive reality, and gain social legitimacy within digital society.

This study aims to examine the traces of acculturation between Islam and local culture in Margorejo Village, Kerek District, Tuban Regency. The research is based on the understanding that the spread of Islam in Indonesia occurred peacefully, persuasively, and adaptively, allowing Islamic teachings to interact harmoniously with local traditions without eliminating existing cultural identities. This process produced forms of religious culture that combine Islamic values with local customs and continue to be preserved by the community. The study employed a qualitative descriptive approach. Data were collected through observation, interviews with religious leaders, community leaders, and local residents, as well as documentation of religious and social traditions. Data analysis was conducted through data reduction, presentation, and conclusion drawing. The findings show that acculturation is reflected in the tradition of pilgrimage to the tomb of Sheikh Ahmad Subaqir or Mbah Mboja, who is regarded as an important figure in spreading Islam in the region. The pilgrimage serves not only as a spiritual activity but also as a means of strengthening social solidarity. Another form of acculturation appears in the “sedekah bumi” or “manganan” tradition, which expresses gratitude for agricultural harvests and community welfare. The study concludes that Islam and local culture in Margorejo coexist harmoniously and contribute to strengthening religiosity, social solidarity, and cultural preservation.

This study conducts a systematic review of literature concerning the role of Management Information Systems (MIS) in managing Umrah pilgrim data across Indonesia. Employing a Systematic Literature Review (SLR) guided by the PRISMA protocol, the study examined and synthesized 24 peer-reviewed articles published between 2019 and 2026, drawn from Google Scholar, SINTA, and nationally accredited journal portals. Findings indicate that MIS adoption has yielded notable improvements in operational efficiency, data reliability, service transparency, and the overall quality of managerial decision-making within Umrah travel organizations. Web-based MIS remains the predominant technological approach, offering integrated modules for pilgrim registration, document handling, financial tracking, and departure scheduling. At the national level, government-initiated platforms such as SISKOHAT and SISKOPATUH have demonstrated tangible contributions to the administration of Hajj and Umrah services. Nevertheless, persistent obstacles continue to hinder full-scale adoption, including inadequate digital infrastructure in certain regions, inconsistent internet connectivity, and gaps in human resource competencies for operating digital systems. The study argues that embracing MIS is no longer optional for Umrah travel operators; rather, it constitutes a strategic necessity. Future research is encouraged to investigate long-term implementation outcomes, cross-system comparisons, and data security considerations within the broader digital landscape of pilgrimage service management.

The development of social media has brought significant changes in how individuals perceive themselves, especially among female university students who are in the stage of identity formation. Social media is not only used as a communication tool but also as a space that presents homogeneous beauty standards which can influence self-perception. This study aims to analyze the construction of beauty standards on social media and their impact on female students’ self-perception. The research uses a qualitative approach with a literature review method by analyzing 20  relevant academic articles published between 2020 and 2025. Data analysis was conducted using descriptive qualitative techniques, including data reduction, data presentation, and conclusion drawing. The results show that beauty standards on social media are constructed through repeated visual representations and reinforced by algorithmic systems, creating an idealized image of beauty. This condition encourages female students to engage in social comparison, leading to self-dissatisfaction and decreased self-confidence. However, these effects vary depending on individuals’ ability to filter and interpret information. This study highlights the importance of developing critical awareness in social media use to avoid being influenced by unrealistic beauty standards.

The phenomenon of growth in Indonesia’s beauty industry has intensified competition among both global and local skincare brands, including Avoskin. This situation impacts consumer trust Instagram.

The phenomenon of emotional healing has become increasingly prominent in popular culture as the younger generation experiences increasing loss, emotional exhaustion, and numbness. Popular music serves as a medium of expression, representing these emotional dynamics through poetic language and symbolic structures. This study aims to analyze the emotional representation of healing in Umay Shahab's song "Perayaan Mati Rasa" using Roland Barthes's semiotic approach. The research method used is descriptive qualitative, analyzing three layers of meaning: denotation, connotation, and myth, through breaking down the lyrics into several lexicons and reading signs. The results show that (1) denotatively, the lyrics construct an emotional arc from inner tension to self-contemplation; (2) connotatively, the use of diction and imagery represents vulnerability, resilience, and emotional reflection; and (3) at the mythical level, the song constructs release as a form of emotional maturity and loss as a process of identity formation. Thus, this song functions as a cultural representation in interpreting the process of emotional healing in popular culture.

This research explores hedonistic lifestyle patterns as a social reality that grows within peer interactions, both in adolescence and adulthood. The investigation applies a qualitative descriptive literature review by examining national scholarly publications issued from 2016 to 2026. The findings indicate that hedonistic tendencies should not be interpreted merely as individual choices to seek enjoyment. Instead, they emerge from social processes shaped by interaction, peer influence, and shared norms that develop within a group. In this context, peer circles function as influential socialization agents, encouraging conformity so individuals can be accepted and avoid social exclusion. The study also identifies differences in underlying motivations across life stages. Among adolescents, hedonistic behavior is closely linked to identity exploration and self-definition. For adults, however, it is more associated with maintaining self-image, signaling social standing, and displaying markers of achievement. Overall, environmental dynamics, the expansion of consumer-oriented culture, and intensive exposure to social media play significant roles in strengthening this phenomenon in Indonesia.

Intellectual property rights (IPR) are an important legal tool for trademark ownership, protecting business quality, and protecting a company's economic interests. Consumers build trust in trademarks because they signal distinct product quality and reflect a positive and consistent corporate image. Trademark protection is regulated by national law under Trademark Law No. 20 of 2016, which provides legal certainty for trademark owners. This law stipulates that a trademark is only valid if it has distinctive elements, is not imitative, and has been officially registered with an authorized institution. The "first come, first served" principle in Indonesian trademark law can be interpreted as a mechanism that grants rights to the first party to file a valid application. However, the application of this principle in practice often raises complex legal issues, particularly when a trademark has already gained widespread public recognition prior to its formal registration. This study focuses on evaluating this legal protection through a normative legal research method by examining applicable laws, regulations, and court decisions related to trademark disputes in Indonesia. The Geprek Bensu dispute has attracted public attention because it highlights the conflict between legal provisions regarding trademark ownership and public perception. This case demonstrates that the existing legal framework still requires further refinement to balance the interests of trademark registrants with those of parties who have built public reputation through prior commercial use. Therefore, legal reform and consistent law enforcement are essential to ensure fair and comprehensive trademark protection in Indonesia.

The abuse of authority by public officials within Indonesia’s governmental administration has become an increasingly urgent issue to address. Such misconduct undermines the fundamental principles of good governance  including transparency, accountability, and justice which are essential for ensuring efficient and effective government operations. This study aims to conduct an in-depth analysis of the forms of abuse of authority by public officials, the factors influencing such behavior, and its impact on the effectiveness of governance and public trust. The research employs a normative approach with a prescriptive legal method, analyzing legislation related to the abuse of authority as well as a case-based approach to explore the implementation of authority by public officials in governmental practice.The findings indicate that abuse of authority may occur in various forms, such as exceeding the limits of granted power, conflating different authorities, or acting arbitrarily for personal or group interests  all of which contradict the principle of legality governing governmental actions. Moreover, such practices negatively affect the quality of public services and tarnish the image of governmental institutions. The study also finds that although Law No. 30 of 2014 on Government Administration provides a clear legal framework, its implementation remains hindered by weak internal and external oversight systems. Therefore, this research recommends strengthening more effective supervision mechanisms, enhancing transparency in administrative decision-making processes, and involving the public in monitoring efforts to ensure that public officials exercise their authority in accordance with established objectives in pursuit of a clean and just government.
