This research investigates thermal material properties and performance characteristics for high-speed vessel components subjected to extreme thermal stress during sustained high-speed operations. High-speed vessels including patrol boats, fast ferries, and naval craft experience elevated thermal loads from high-power density propulsion systems, aerodynamic heating, and sustained operational intensities creating demanding conditions for structural and mechanical components. Through qualitative analysis involving naval architects, materials engineers, high-speed vessel operators, and component manufacturers, this study examines how material thermal properties affect component durability, performance, and safety while identifying optimal material selections for critical applications. Results demonstrate that advanced thermal materials including high-temperature aluminum alloys, titanium alloys, ceramic composites, and thermal barrier coatings can extend component service life by 40-70%, improve thermal management effectiveness by 25-45%, and enhance operational reliability compared to conventional materials. Key implementation challenges include material cost premiums of 150-300%, manufacturing complexity, limited operating experience, qualification testing requirements, and supply chain constraints. Findings reveal that strategic thermal material selection for critical components represents essential enabling technology for high-speed vessel performance, reliability, and operational availability supporting defense, commercial, and emergency response applications requiring sustained high-speed capabilities. This research contributes to marine materials engineering literature by providing evidence-based frameworks for thermal material selection applicable to diverse high-speed vessel applications.

The development of multimedia-based interactive games requires a system capable of effectively managing game logic, character behavior, and the integration of visual and animation elements. This study aims to implement GDScript in the development of a 2D RPG game using the Godot Engine. The research method was carried out through the design of scene and node structures, the implementation of game logic using GDScript, and the application of Finite State Machine (FSM) to regulate enemy behavior. GDScript is used to control character movement, animation systems, and interactions between players and objects in the game. The implementation of FSM allows enemies to have dynamic behavior through state settings such as idle and wander. Functional testing results show that the game system can run according to the design and is capable of producing responsive interactions. In addition, the use of modular architecture in the Godot Engine facilitates system development and maintenance. Based on the research results, the Godot Engine and GDScript are considered effective for developing multimedia-based interactive games.

International student enrollment is a critical driver of financial sustainability for Higher Education Institutions (HEIs). While advanced forecasting is standard in the corporate sector, its application in educational planning remains limited. This study addresses this gap by comparing the predictive performance of ARIMA, Facebook Prophet, and Long Short-Term Memory (LSTM) models. Using a publicly available annual dataset from a US-based institution (2000–2022), the analysis employed a strategic partition training on 2000–2017 and testing on 2018–2019 to validate models on stable, pre-pandemic data. Empirical results revealed that the statistical ARIMA (2,1,0) model demonstrated superior accuracy, achieving a Mean Absolute Percentage Error (MAPE) of 1.26%. Conversely, Prophet (11.81%) and LSTM (13.84%) struggled with the limited sample size, failing to generalize effectively compared to the linear approach. The findings suggest that for annual enrollment trends, parsimonious statistical models outperform complex deep learning architectures, providing administrators with a robust, accessible framework for data-driven strategic decision-making.

The global tourism industry is experiencing significant growth with a contribution of USD 11.1 trillion to the world's GDP by 2024. Maluku Province has extraordinary natural tourism potential, one of which is the Waai Tree House in Central Maluku Regency which offers a glamorous camping (glamping) concept with the natural beauty of the mountains. Despite having natural advantages, this tourist attraction faces problems of damaged access roads, lack of supporting facilities, and not optimal promotional strategies. This research aims to identify strategic factors through SWOT analysis and formulate effective development strategies to increase the competitiveness of Waai Tree House tourism in a sustainable manner. The research method uses a descriptive qualitative approach with data collection techniques through participatory observation, in-depth interviews with managers and visitors, visual documentation, and literature studies. The data is analyzed using SWOT analysis to identify strengths, weaknesses, opportunities, and threats, then formulated into four development strategies. The results show the main strengths in the form of natural beauty, unique glamping concepts, and personal service, while the critical weaknesses are damaged road infrastructure and limited facilities. Opportunities include digital promotion and collaboration with governments, while threats include limited accessibility and competition for new destinations. The strategy formulation resulted in four approaches: SO (intensive digital promotion), WO (priority infrastructure improvement), ST (service differentiation), and WT (consistent facility updates) strategy. The implementation of the WO strategy is a top priority with a gradual roadmap of 6-24 months. This research contributes to a contextual strategic framework for the development of glamping tourism in the remote archipelago of Eastern Indonesia.

This systematic review maps how innovation, technology adoption, and Islamic entrepreneurial behaviors are intertwined and contribute to the SDGs. Searches in Scopus followed PRISMA 2020: of the 166 initial records, 46 were eliminated prior to screening; 120 filtered by title–abstract; 45 read in full; and 25 articles were analyzed in depth. Four RQs lead the synthesis: the form of innovation/adoption (RQ1), impact on behavior and performance (RQ2), and their relationship to the SDGs (RQ3). The findings show five complementary faces of innovation: (1) process-organization (knowledge management, open innovation; innovation capability), (2) sharia business/finance models (sharia venture capital, agricultural value chain finance), (3) financial and platform digitalization (fintech, Islamic crowdfunding), (4) technological innovation in business models (e.g., urban farming–aquaponics) that are value-framed, and (5) halal product/marketing innovation (halal assurance and halal trust). Behind that, the drivers are layered: individual values and psychology, Islamic HRM cultural orientation and organizational learning, Islamic finance architecture and regulation, and access to digital literacy and trust in the platform. The impact is multidimensional performance, access to ethical capital, halal market behavior, and social and religious environmental outcomes with strong contributions to SDG 8 and SDG 9, and footprints on SDGs 1–2, 3, 10, 11, 12, 13, 16, 17. This SLR offers an integrated financial innovation value framework and proposes SDGs micro-indicators; limitations mainly in the variation of measurements and the dominance of cross-section designs.

The Great Mosque of Banten is a historical heritage that reflects cultural acculturation and the glory of Islam in the Indonesian archipelago. This study aims to analyze the forms of collaboration between the government, local communities, and site managers in preserving the Great Mosque of Banten using the Collaborative Governance theory by Ansell and Gash (2007). A descriptive qualitative approach was applied through interviews, field observations, and document studies conducted in the Great Mosque area. The findings reveal that collaboration among stakeholders has not yet reached optimal levels due to limited communication, trust gaps, and conflicting interests. Nevertheless, functional cooperation has emerged through joint activities in sanitation, security, and tour guide training. Based on the five indicators of the collaborative process, direct communication (face to face dialogue) and trust building remain major challenges, while shared understanding between government agencies, the foundation, and the community has begun to develop. This study highlights the importance of sustainable collaborative governance in preserving the religious, historical, and social values of the Great Mosque of Banten while supporting the welfare of the surrounding community.  

This study is motivated by the position of traditional music as a cultural element that not only functions aesthetically but also plays an important role in constructing social meaning, symbolism, and collective identity within a community. This article aims to examine the social meaning and function of Tagonggong music in the Tulude tradition of the Sangihe community in Londoun Village as a diaspora community. The research uses a qualitative method with a cultural ethnographic approach through participatory observation, unstructured interviews with traditional elders, Tagonggong players, and community leaders, as well as documentation. Data analysis was conducted descriptively and interpretatively using Alan P. Merriam's theoretical framework on the function of music. The results of the study show that Tagonggong music has a multidimensional function in the Tulude tradition, including symbolic communication, emotional expression, representation of cultural identity, reinforcement of social norms, and social integration and cohesion within the community.Tagonggong not only functions as an accompaniment to ceremonies, but also as a sacred musical instrument that connects the relationship between humans, ancestors, and God, while also marking the space and time of the ceremony. This finding confirms that Tagonggong is a living cultural archive that preserves the collective memory and ethnic identity of the Sangihe community in exile. Implicitly, this research enriches Indonesian ethnomusicology studies by positioning traditional music as an active social text in maintaining the cultural structure and solidarity of the communities that support it.

This study reinterprets Kakawin Panca Dharma through Carl Gustav Jung’s analytical psychology, viewing kalepasan (liberation) as a symbolic manifestation of the poet’s (kawi’s) inner transformation through the process of individuation. While previous studies have treated Kakawin Panca Dharma as a theological or ethical text, this paper argues that the discourse of kalepasan reflects archetypal structures of the psyche—shadow, anima, and Self—within the creative process of the kawi-wiku. Through a qualitative hermeneutic method integrating philological reading and Jungian symbolic interpretation, this research uncovers how motifs of silence (sunya), detachment (putus), and purification (wimala) embody stages of psychological transformation. The findings reveal that Kakawin Panca Dharma serves as a “temple of language,” where poetic creation functions as an act of active imagination, integrating conscious and unconscious dimensions of the self. Liberation thus signifies not only spiritual transcendence but psychological wholeness—the realization of the Self archetype.  

Unequal access to population administration services remains a persistent governance challenge in archipelagic and geographically constrained areas, where spatial dispersion, limited connectivity, and high mobility costs systematically hinder citizens’ ability to obtain legal identity documents. In island regions, weak sea transportation networks, weather-dependent travel, and long distances to administrative centers reduce the feasibility of conventional, office-based service delivery, producing administrative exclusion that undermines equal citizenship. These barriers also intersect with socio-administrative realities, including the prevalence of unregistered marriages (nikah sirri), which constrains civil registration processes and delays the formal recognition of marital status and household composition within population administration systems. Against this backdrop, this review article aims to synthesize reputable scholarly literature on pelayanan jemput bola (mobile/outreach public services) as a policy strategy to advance service inclusivity and administrative justice in population administration, particularly for geographically marginalized communities. Methodologically, the article employs a thematic–conceptual literature review, systematically identifying and analyzing peer-reviewed journal articles and conference proceedings published primarily within the last five to ten years across recognized academic databases. The synthesis identifies key rationales and conceptualizations of outreach services, maps major implementation models (mobile units, community-based outreach, integrated one-stop outreach, and hybrid outreach–digital arrangements), and consolidates recurrent success factors, including local state capacity, inter-actor coordination, frontline discretion, and policy support. It also highlights persistent challenges such as logistical uncertainty, resource constraints, uneven digital readiness, and governance fragmentation across island territories. The article concludes that mobile/outreach population administration services can substantially improve equitable access to legal identity and strengthen civil rights realization in archipelagic contexts, but only when embedded in capacity-building and geography-sensitive governance arrangements. By integrating fragmented strands of scholarship, the review offers a conceptually grounded framework and policy-relevant implications for designing sustainable and just population administration reforms in island regions.

This study aims to examine the lived experience of the Eucharist as an experience of love in the lives of Catholic families at St. Michael Buluq Sen Station, Good Shepherd Parish of Ritan Baru, Archdiocese of Samarinda, through the lens of Henri Nouwen’s spirituality. It employs a descriptive qualitative approach, with data gathered through observation, semi-structured interviews with eight active Catholic families, and a review of relevant literature. Data were analyzed through systematic stages of reduction, display, and conclusion drawing, supported by source and method triangulation. The findings show that the experience of the Eucharist is expressed in four interrelated dimensions of Nouwen’s spirituality: being chosen, blessed, broken, and shared. “Being chosen” appears in the family’s awareness of belonging to a community loved by God; “being blessed” is reflected in gratitude for life; “being broken” is revealed in the willingness to embrace suffering and sacrifice; and “being shared” is embodied in active participation in Church ministry and social engagement. This study affirms the Eucharist as a transformative source shaping family relationships and social life, enriching theology and supporting formation in rural families.

The SIAP Application is an innovation developed as a solution to support the archiving business process in the Planning Bureau. Currently, most employees still use computers and a web-based cloud system developed by Pusdatin using the PHP programming language as a storage medium for files that are no longer actively used and are categorized as dynamic archives. However, the cloud system does not have a well-structured archive management system, which often causes difficulties when employees need to retrieve archived files. As a result, employees must search for files manually by checking archived documents one by one in the cloud. This process is time-consuming and may lead to problems such as difficulties in finding files and the risk of data loss. Based on these conditions, the SIAP Application was developed to improve the effectiveness and efficiency of archive management in the Planning Bureau.The SIAP Application has an advantage in the archiving process, where employees can easily search for archives using the letter number or subject that has been entered into the system. The system will automatically display the required archive, making the retrieval process faster, more accurate, and more organized compared to the previous cloud system.The development of the SIAP Application uses PHP and HTML as the programming languages, with Bootstrap and Tailwind CSS as the user interface frameworks, and MySQL as the database. The system development method used is the Waterfall model, problem analysis is carried out using the PIECES method, and system testing is conducted through black-box testing and the System Usability Scale (SUS) to measure system usability.

The management of village development program archives plays a vital role in supporting effective, transparent, and accountable village governance. However, in many villages, including Kalembu KanaiKa Village in Wewewa Barat District, archive management is still conducted conventionally without the support of a structured information system. This condition creates several challenges, such as difficulties in accessing data, low administrative efficiency, and weak documentation and accountability of village development activities. Therefore, this study aims to examine the development of an information system for managing village development program archives based on local conditions and needs. The research seeks to identify the actual condition of archive management, analyze constraints faced by village officials, and formulate directions for developing an appropriate archive management information system in Kalembu KanaiKa Village. This study employed a qualitative method with a case study approach. Data were collected through in-depth interviews, observations, and document analysis involving village officials responsible for archive management and development program implementation. The results reveal that archive management has not been optimal due to limited human resources, inadequate facilities, and minimal use of information technology. Despite these limitations, village officials show readiness and willingness to adopt a simple and user-friendly archive management information system tailored to the village’s social and institutional capacity. These findings indicate that the development of archive information systems requires not only technical solutions but also attention to social, institutional, and capacity-building aspects.

This study aims to develop an Indonesian traffic sign detection system using a transfer learning approach to improve road safety and traffic efficiency. The dataset was obtained from Kaggle and consists of 2,100 images across 21 traffic sign classes. The research stages include data collection, preprocessing to reduce noise and normalize image brightness, object detection using YOLOv5, and classification based on transfer learning with ResNet, VGG-16, and MobileNet architectures. Model performance was evaluated using accuracy, precision, recall, and F1-score metrics. Experimental results indicate that the YOLOv5 model is capable of detecting traffic sign objects; however, the classification performance remains relatively low, with a mean Average Precision (mAP) value of 0.17. These findings suggest that further optimization is required in data preprocessing, dataset quality, and model parameter tuning to achieve better performance. This study demonstrates that transfer learning has significant potential for developing computer vision-based traffic sign detection systems, although further improvements are necessary to ensure robustness under real-world Indonesian traffic conditions.

The rapid development of information technology has provided significant opportunities to improve the efficiency of academic administration in schools. One of the common problems faced by educational institutions is the manual process of subject scheduling, which is time-consuming and prone to schedule conflicts among teachers, classes, and learning time. This problem is also experienced by SMPK Flos Carmeli, where the preparation of subject schedules has not yet been supported by an integrated computerized system. This study aims to design and develop a web-based subject scheduling application at SMPK Flos Carmeli using the Model–View–Controller (MVC) architecture. The research method employed is Research and Development (R&D) with the Waterfall software development model, which includes the stages of requirements analysis, system design, and application implementation. Data were collected through interviews, observations, and literature review to obtain system requirements that align with the school’s conditions. The application was developed using native PHP with the implementation of the MVC pattern to produce a structured, maintainable, and flexible system. The results show that the developed application is able to support the subject scheduling process in a faster, more accurate, and well-organized manner. The system provides features for managing teacher data, class data, time slots, schedule arrangement, and schedule printing, thereby minimizing schedule conflicts and improving the efficiency of school administrative work. Therefore, this subject scheduling application is expected to support the digitalization of academic administration and enhance the effectiveness of the teaching and learning process at SMPK Flos Carmeli.

Correspondence management is very important in government administration because it helps all parts of the organization communicate more easily. The purpose of this study was to assess the manual mail management system at the Riau Province Human Resources Development Agency (BPSDM) and find barriers and conformity with applicable regulations, especially Riau Governor Regulation No. 45/2019. The research was conducted using a descriptive qualitative approach involving participatory observation, in-depth interviews, literature research, and visual documentation. The results showed that the manual system used causes recording errors, delays in letter distribution, and difficulties in archive retrieval. In addition, the current provisions have not fully digitized the official manuscript and archive classification. Limitations in budget, infrastructure and HR training lead to mismatches between practices and regulations. The results show that to increase bureaucratic efficiency and improve accountability of public information, we must shift to a digital-based mail management system. According to this study, digitization of archives through applications such as Srikandi should begin immediately. This is necessary so that BPSDM can meet the demands of fast and accurate information services in the era of information technology.

The application of Large Language Models (LLM) in public services encourages government agencies to adopt Retrieval Augmented Generation (RAG)-based chatbots as interfaces for regulatory knowledge and official documents. Although RAG is designed to increase the supportability of answers to authoritative sources, various studies show that this system is still vulnerable to hallucinations, which have the potential to reduce public trust and pose legal risks. This article presents a Systematic Literature Review (SLR) on the use of RAG in government chatbots with a focus on the definition, mitigation strategies, and evaluation of groundedness. The literature search was conducted in the period 2021–2025 through the SpringerLink, Scopus, and Taylor & Francis databases, resulting in 7,947 articles filtered using the PRISMA framework to obtain 100 articles Q1–Q2. Based on eight research questions, this study maps publication trends, document domains, RAG architecture, retrieval strategies, definitions of groundedness, and evaluation metrics used. The SLR results indicate conceptual fragmentation in the definition and measurement of groundedness, with the dominance of text-similarity-based metrics that are inadequate for regulatory contexts. As a conceptual contribution, this article formulates the Semantic Alignment Score (SAS) as a groundedness metric based on semantic alignment, evidence coverage, and entailment relationships, positioned to support the evaluation and auditing of government document chatbots.

The land conflict between the Pandumaan-Sipituhuta indigenous community and PT Toba Pulp Lestari is a form of agrarian conflict involving claims to control customary territory and corporate interests. This study aims to analyze the role of the Indigenous Peoples Alliance of the Archipelago (AMAN) in this conflict. The approach used was qualitative with data collection techniques through in-depth interviews and documentation studies. The results of the study indicate that AMAN plays a significant role in various aspects, such as legal assistance, mass mobilization, community organizing, legal education, and village deliberations. In addition, AMAN also builds networks with various parties to strengthen the bargaining position of indigenous communities. Through these roles, AMAN has succeeded in increasing the bargaining power of the Pandumaan-Sipituhuta indigenous community in facing the conflict with PT Toba Pulp Lestari. This study confirms that advocacy organizations such as AMAN have a crucial role in fighting for the rights of indigenous communities in land disputes, as well as being agents of change in resolving agrarian conflicts.
