Islamic architecture in the archipelago cannot be understood as simply a transfer of physical forms from the Middle East to Southeast Asia. It is the result of a deep cultural dialogue between universal Islamic principles and local wisdom that has been formed since pre-Islamic times. When Islam spread in the archipelago, it did not exist as a force that negates Hindu, Buddhist, and vernacular traditions, but rather proceeded through visual and structural synthesis that gave birth to a distinctive and hybrid Islamic architectural identity. One of the most iconic manifestations of this process is the use of overlapping roofs in historic mosques such as the Great Mosque of Demak and the Great Mosque of Banten. Different from typical Persian or Mediterranean stone domes, this multi-storey wooden structure is inspired by the concept of Meru in Hindu-Javanese architecture. The choice is not only symbolic, but also a functional adaptation to the tropical climate, as it allows for efficient rainwater disposal as well as optimal natural ventilation. Spatially, the placement of mosques follows the concept of Catur Gatra Tunggal, which is the integration of mosques with squares, government centers, and markets. This pattern reflects the integration between the spiritual, political, and economic life of the community. In the interior, the use of Saka Guru shows the appointment of local construction techniques as the main element of worship buildings. Aspects of syncretism are also seen in ornamentation, where pre-Islamic figurative motifs are transformed into flora and calligraphy patterns that are in harmony with the principles of Islamic aniconism. Thus, the archipelago's Islamic architecture represents Islam as an inclusive and contextual force that is able to process local traditions into a sustainable new identity.

This study explores the integration of Science, Technology, and the Arts (IPTEKS) within an educational psychology framework to support the development of creativity, innovation, and collaboration among prospective Christian religious education teachers in West Java. Using a mixed-methods approach with a sequential explanatory design, the research combines quantitative and qualitative perspectives to obtain a comprehensive understanding of the phenomenon. Quantitative data were gathered through questionnaires distributed to prospective teachers, while qualitative data were obtained through in-depth interviews and participatory observations involving selected informants. The findings indicate that meaningful integration of IPTEKS contributes positively to the development of creative thinking, innovative teaching practices, and collaborative learning skills. Qualitative insights further reveal that institutional support, continuous professional development, and contextualized learning environments play a crucial role in optimizing the impact of IPTEKS integration. The study highlights the importance of aligning technological integration with psychological and pedagogical principles. It concludes that teacher education programs need to redesign curricula and training models that holistically integrate IPTEKS and educational psychology to foster relevant, transformative, and value-based learning in Christian education contexts.

Traditional food is a national asset. It not only serves as a source of energy for the community, but also serves as a form of food security, an economic driver, a source of healthy food, and a culture steeped in noble values. The widespread consumption of unhealthy foods by students, especially elementary school students, is one of the reasons for this outreach activity. The health issues surrounding junk food must be addressed by offering healthy alternatives, such as traditional foods. Traditional food is not only related to food, but can also be linked to ethnomathematics, where culture in the form of food is studied from a mathematical perspective. Elementary school students not only consume traditional foods but also interpret these foods in mathematical contexts, such as geometry and numbers. In this way, students will be able to visualize mathematical elements not only when reading math textbooks but also when consuming traditional foods that are part of their daily environment. Despite their traditional nature, students actually enjoy some traditional foods. This is a frequent conflict between the current generation and traditional culture. They better understand how to prepare traditional foods, appreciate the richness of local culture, and develop a love for their culture and homeland.

The rapid development of information technology encourages companies to optimize administrative sistems, including employee payroll processes, to ensure greater operational effectiveness and data accuracy. PT Infokom Internusa still utilizes manual and semi-computerized methods in payroll management, which may lead to calculation errors, data duplication, data inconsistency, and delays in report generation. These issues can affect overall organizational performance and decision-making efficiency. This study aims to design and develop a Java-based Employee Payroll Information Sistem to improve efficiency, accuracy, transparency, and security in payroll processing. The research employs the Waterfall software development model, which consists of requirement analysis, sistem design using Unified Modeling Language (UML), implementation using the Java programming language and MySQL database, and comprehensive sistem testing. The results indicate that the developed sistem is capable of automating salary calculations, allowances, deductions, tax computations, and report generation in an integrated and structured manner. The sistem also reduces manual errors, minimizes redundancy, and accelerates payroll administration processes. Therefore, the proposed information sistem can significantly enhance the performance, productivity, and service quality of the HR and finance departments at PT Infokom Internusa.

Significant changes occurring today are characterized by technological disruption, demographic shifts, globalization, and economic instability. The combination of these factors creates complex challenges for human resources (HR) in adapting and enhancing their capabilities. The purpose of this study was to examine the relationship between organizational commitment and perceptions of transformational leadership style with Organizational Citizenship Behavior of teachers in Surabaya. The research subjects were 397 teachers in Surabaya, East Java. The sampling technique used was purposive sampling. Data was collected through scale filling using Google Forms. The measurement instruments in this study were the Organizational Citizenship Behavior Scale, the Organizational Commitment Scale, and the Transformational Leadership Style Perception Scale. The data analysis used multiple linear regression analysis. The results showed that there was a significant positive relationship between organizational commitment and perceptions of transformational leadership style with Organizational Citizenship Behavior. The higher the organizational commitment and perceptions of transformational leadership style, the higher the Organizational Citizenship Behavior among teachers. There was a significant relationship between organizational commitment and Organizational Citizenship Behavior, and there was also a significant positive relationship between perceptions of transformational leadership style and Organizational Citizenship Behavior. The higher the perceptions of transformational leadership style, the higher the Organizational Citizenship Behavior among teachers.

State-based conservation in Indonesia often faces institutional failure and social resistance, resulting in continued deforestation. Conversely, Indigenous conservation models in West Java, specifically the Leuweung Larangan (forbidden forest), demonstrate significant ecological resilience. However, the legal standing of these customary practices within Islamic jurisprudence remains under-theorized, creating a dichotomy between Adat (custom) and Sharia. This study proposes a juridical reconstruction of the Sundanese taboo mechanism (Pamali) as Jarimah Ta’zir (discretionary sanction) to strengthen environmental law enforcement. Utilizing a socio-legal approach and ecological hermeneutics, this research analyzes Yusuf al-Qardhawi’s concept of Fiqh al-Bi’ah and Seyyed Hossein Nasr’s sacred science, alongside relevant empirical data on Indigenous forest governance. The findings demonstrate that Leuweung Larangan structurally manifests as Hima Syar’i (sacred protected zone). Operationally, Pamali functions not merely as a cultural myth, but as a preventive legal instrument (Sadd al-Dzari’ah) where environmental violations constitute religious criminal acts. This creates a "Sundanese Eco-theology" model that establishes a double-layered compliance system—social sanctions and theological liability—proving more effective for carbon preservation than state regulations alone. The study recommends integrating this model into the Green Constitution framework to resolve tenurial conflicts and enhance climate resilience.

This study aims to evaluate the public transportation service policy of Trans Jatim Bus Corridor 2, operating on the Mojokerto–Surabaya route, using the six evaluation indicators proposed by William N. Dunn: effectiveness, efficiency, adequacy, equity, responsiveness, and appropriateness. Employing a qualitative descriptive approach, data were collected through interviews, direct observations, and secondary data analysis. The findings reveal that the Trans Jatim Corridor 2 service has significantly contributed to improving accessibility and mobility for the people of East Java. In terms of effectiveness, the service meets transportation policy objectives by offering strategic routes, consistent schedules, and accessible bus stops. Efficiency is demonstrated through optimal utilization of limited fleets and operational costs, while still meeting high passenger demand. Regarding adequacy, the service is generally sufficient; however, overcrowding during peak hours indicates the need for capacity improvements. Equity is reflected in the widespread distribution of bus stops, although disparities remain in the availability of facilities and route information across several stops. The service shows high responsiveness through quick handling of passenger complaints via applications and social media. Additionally, service appropriateness is evident in its punctual operations supported by GPS-based monitoring and real-time information through the TRANSJATIM-AJAIB application. Overall, the evaluation shows that Trans Jatim Corridor 2 provides effective, efficient, and responsive public transport services, yet requires improvements in capacity and equitable distribution of facilities to achieve optimal service quality.

Participatory village development planning is often treated as a technical-administrative routine. In practice, however, planning is inseparable from political dynamics that shape who participates, whose interests prevail, and how scarce resources are allocated. This community empowerment program (PKM) in Kedung Udi Village, Trawas District, Mojokerto Regency, East Java, aimed to strengthen village governance by enhancing the capacity of village officials and community representatives to design and facilitate participatory planning while explicitly addressing the political dimension of planning. The main intervention was a workshop conducted on 22 August 2025, preceded by coordination and situational observation. Workshop modules emphasized: (1) planning as a political decision; (2) navigating dual arenas: formal (Musdes/Musrenbang and RPJMDes, RKPDes, APBDes) and informal (elite networks and gatekeeping); (3) multi-level contestation and policy alignment; and (4) practical tools, including power–interest mapping, programmatic agreements, program tagging for alignment with district planning documents, and transparency/anti elite capture mechanisms. The program resulted in improved participant literacy regarding power relations in planning and produced a follow-up action plan oriented toward institutional advocacy, continuous social control, and routine capacity reinforcement through a university and village partnership.

Belawa Village, located in Lemahabang District, Cirebon Regency, West Java, is famous for the Labi-labi Belawa tourist attraction. This study aims to develop a sustainable tourism village at the Cikuya Tourist Attraction in Belawa Village. This model is expected to be an integrated solution to support the implementation of sustainable tourism. The research method used is descriptive qualitative, with quantitative data analysis. The results of the study show that the implementation of sustainable tourism in Cikuya is evident through environmental preservation and the conservation of the Belawa turtle habitat. Although the management is not yet optimal, there are practices of utilizing organic waste, such as chicken manure for animal feed and coconut shells for souvenirs, supporting the circular economy concept. Community participation in cultural activities also supports the social and cultural aspects of sustainable tourism, although it is still incidental and has not yet been programmed sustainably. However, the implementation of sustainable tourism in Cikuya is not yet fully optimal, despite having strong natural and conservation potential. Structural and operational barriers, such as accessibility, human resources, institutional governance, economy, socio-culture, and policy support, affect the effectiveness of applying sustainability principles.

This study examines the transformation of Fixed-Term Employment Agreements (PKWT) in East Java within the context of Indonesia's flexible economy era, particularly following the enactment of the Job Creation Law (UU Cipta Kerja No. 6/2023). The research analyzes the legal protection challenges faced by contract and outsourcing workers in East Java Province from 2020–2025. Using a normative juridical approach combined with empirical data from the Central Statistics Agency (BPS) and the Ministry of Manpower, this study reveals that despite regulatory improvements, significant gaps remain in the implementation of labor protection. Key findings indicate that contract workers in East Java, estimated at 59.17% of the informal workforce in 2024, face uncertainties regarding contract duration, compensation rights, and social security. The study recommends strengthening supervision mechanisms, clarifying regulations on gig economy workers, and enhancing bipartite negotiation processes to ensure balanced protection between business flexibility and workers' fundamental rights, while also promoting legal certainty and sustainable employment relations in the regional labor market.

This study analyzes the sociolinguistic phenomena of code-switching and code-mixing in the academic context of students in Pekalongan, Central Java. As a region with diverse backgrounds dominated by the Pekalongan dialect (Ngapak Javanese), interactions between students create space for complex language dynamics. This study aims to identify variations, roles, and factors that cause code-switching and code-mixing in student interactions. The method applied is descriptive qualitative with data collection through inactive participant observation, recording, and in-depth interviews at various universities in Pekalongan. Data analysis is carried out through the steps of data reduction, data presentation, and verification using triangulation techniques. The results show that the application of language codes is divided into two categories: an internal category that includes Indonesian and regional languages (Javanese), and an external category that includes foreign languages (English or Arabic). Code-mixing can be found at the word, phrase, and clause levels. The main factors that drive this phenomenon include participants, conversation themes, situational circumstances, and the purpose of communication in building solidarity among group members (ingroup).  The Pekalongan dialect plays a crucial role as a means of communication to build closeness and demonstrate local identity, amidst the need to use formal language on campus. This research concludes that code-switching and code-mixing are not merely linguistic phenomena, but also ways in which students adapt socially to balance their cultural identity with academic demands.

This study developed the Weton-Based Leadership Model as a leadership framework that integrates Javanese cultural values from the weton system with modern leadership theories, such as transformational, servant, charismatic, and situational leadership. Using a postmodern paradigm with an exploratory qualitative approach, this study utilizes pattern matching and explanation building methods through in-depth interviews with cultural experts and human resource management practitioners, as well as analysis of Javanese cultural documents. The results of the study identify five key components in the model, namely self-awareness, value alignment, situational adaptability, team harmony, and risk governance. These five components interact with each other to form contextual leadership that is in harmony with personal identity, organizational culture, and environmental demands. The practical implications of this study include the use of weton as a reflective instrument in recruitment, personalized leadership development, and the strengthening of an inclusive organizational culture. Further research is recommended to test this model in various industrial contexts through quantitative methods and longitudinal approaches.

Income inequality and poverty continue to be major challenges in Indonesia's industrial areas, especially in DKI Jakarta, West Java, and Banten, although minimum wage policies continue to be developed as a form of protection for low-income workers. These policies theoretically serve as an instrument for income redistribution and improvement of labor welfare, but their effectiveness in reducing inequality and reducing poverty rates is still questionable, especially in areas with highly industrialized economic structures. This study aims to analyze the influence of income inequality, poverty rate, economic growth, and unemployment rate on the dynamics of the provincial minimum wage in the 2016–2023 period. The study used secondary data obtained from the Central Statistics Agency and analyzed using panel data regression to obtain a comprehensive empirical picture of the factors determining the minimum wage. The test results show that the Fixed Effect Model is the most suitable model for capturing variations between provinces and between times. Key findings reveal that poverty levels and economic growth have a significant influence on changes in the minimum wage, while income inequality and unemployment rates have no significant influence. The conclusion of the study emphasizes that the minimum wage policy is not effective enough in reducing income inequality and reducing poverty without the expansion of the formal sector, improving the quality of the workforce, and distributing economic growth more evenly between industrial areas.

The plastic recycling industry generates wastewater that poses a potential threat to aquatic environments if not managed optimally. Performance evaluation of Wastewater Treatment Plants (WWTP) is typically conducted partially by comparing outlet parameters against effluent standards, often failing to depict water quality conditions holistically. Therefore, this study employs the Water Quality Index (WQI) approach using the Canadian Council of Ministers of the Environment (CCME) method to evaluate the performance of PT X's WWTP in East Java. This research utilized secondary data from inlet and outlet wastewater quality tests over 23 months (January 2024–November 2025), covering 10 parameters. Analysis was conducted by calculating removal efficiency and determining factors F1 (scope), F2 (frequency), and F3 (amplitude) as the basis for the WQI-CCME calculation. The results indicate that the WWTP achieved high efficiency (>80%) in reducing dominant parameters such as TSS, TDS, BOD, and COD. However, violations of effluent standards were still observed in certain parameters. The obtained WQI-CCME value was 69,30, categorized as "Fair" with a moderate level of violation. These findings demonstrate that although the WWTP meets regulatory standards, the WQI-CCME approach provides a more comprehensive assessment of performance. Optimization of advanced treatment units is recommended to improve effluent quality and sustainable WWTP performance.                                                                   

This study aims to analyze the influence of self-discipline and burnout (Thīna-Middha) on active participation in religious activities among Buddhist adolescents aged 15–18 in Central Java. The approach used is quantitative with a survey method, and the sampling technique is cluster sampling. The instrument used is a semantic differential scale questionnaire to measure self-discipline, burnout, and active participation. Data analysis is performed using multiple linear regression to determine the influence of each variable on active participation. The results show that self-discipline has a positive and significant effect on active participation in Buddhist religious activities, while burnout has a negative and significant effect. These two variables contribute 41.1% to active participation in religious activities. These findings highlight the importance of self-discipline as a factor that drives active participation, as well as the negative impact of burnout on adolescents' involvement in religious activities. The implications of this study can be used as a basis for designing more effective and targeted programs for Buddhist adolescents, considering the factors of self-discipline and efforts to mitigate burnout. These programs need to be tailored to the spiritual and psychological needs of adolescents to enhance their active participation in religious activities.

The Regional Regulation Formation Agency (Bapemperda) is a legislative body under the Regional People's Representative Council (DPRD) that plays a key role in the creation of regional regulations. This study analyzes the function of the Bapemperda of the West Java Provincial DPRD in 2025 throughout the entire regulation formation process using a qualitative approach. The results show that Bapemperda carries out strategic tasks including the preparation of Propemperda (Regional Regulation Proposals), coordination and harmonization of Draft Regional Regulations (Raperda), monitoring discussions, and evaluating the content of the material. In 2025, Bapemperda established 10 Draft Regional Regulations (Raperda) (3 proposed by the DPRD and 7 proposed by the Governor). Bapemperda functions as a bridge for political communication and quality control of regional regulations. Its effectiveness is influenced by coordination, member professionalism, and consistent application of regulatory principles. Challenges faced include time constraints, complexity of substance, and political dynamics. The study recommends strengthening institutional capacity and optimizing the documentation system to support good governance.

This study explores the implementation of the Problem-Based Learning (PBL) model combined with the Culturally Responsive Teaching (CRT) approach through the utilization of various forms of digital content to optimally enhance students’ learning outcomes. The research employs a descriptive qualitative design aimed at gaining an in-depth understanding of the learning process being implemented. The primary data were obtained from an analysis of the Grade VIII Indonesian language teaching module, while supporting data were collected through interviews with students of the Teacher Professional Education (PPG) program involved in the learning process. The findings indicate that the design and implementation of learning activities followed the stages of PBL systematically, thereby encouraging collaboration, active discussion, and problem-solving activities in the classroom. CRT principles were clearly reflected in the selection of learning materials related to students’ cultural backgrounds, such as speech texts representing Banjar and Javanese cultures. The integration of digital media, including Google Sites, instructional videos, and interactive quizzes, was proven to increase students’ engagement, motivation, and participation during the learning process. Overall, the synergy between PBL, CRT, and digital content created a more relevant, inclusive, and contextual learning environment and had a positive impact on improving students’ learning outcomes.
