The problem of household waste in Kalanganyar Village, Sedati District, Sidoarjo Regency, is increasing along with population growth, while residents' knowledge about waste sorting is still minimal and processing facilities are limited. This community service program aims to increase awareness and cleanliving behavior through education and mentoring on household waste processing based on the 3R concept (Reduce, Reuse, Recycle). This activity adopts an Asset-Based Community Development (ABCD) approach that focuses on mapping and utilizing local potential, such as health cadres, youth organizations, the spirit of mutual cooperation, and the availability of potential land. The implementation methods include appreciative inquiry, focus group discussions (FGDs), in-depth interviews with the Head of the Sopo Nyongko TPS and community leaders, participatory observation, and practical mentoring for housewives, youth organizations, and TPS managers on February 9. The results of the activity showed an increase in residents' understanding of PHBS and waste management, indicated by the enthusiasm of participants during the educational session. The program also successfully activated local agents of change: youth groups began implementing inorganic waste recycling, and health cadres designed a home-based waste sorting system.

Environmental damage caused by human activities has become an increasingly pressing global issue. Poetry as a literary work has the power to represent ecological problems symbolically and critically. This study aims to describe the representation of the impact of the environmental crisis in Taufiq Ismail's poems, namely "Menengajah Ke Atas, Merenungi Ozone yang Tak terlihat" and "Membaca Tanda-Tanda." The analysis is based on Greg Garrard's ecocritical study. This study uses a qualitative method with content analysis techniques. There are two stages of analysis, namely the literal and symbolic meaning of the poems, then an ecocritical interpretation is carried out based on Garrard's categories which include pollution, wilderness, apocalypse, dwelling, animals, and earth. The results of the study indicate that both poems represent the impact of the environmental crisis through health problems due to pollution and radiation, damage to water and forest ecosystems, climate change, threats to human living space, and the decline in biodiversity. The research findings also show that the most dominant categories are pollution and apocalypse, which confirms that the environmental crisis in Taufiq Ismail's poems is the result of human behavior that ignores nature. Thus, Taufiq Ismail's poems not only function as aesthetic works, but also as cultural criticism and moral warnings for humanity.

This study aims to reflect on the theological meaning of natural disasters in Sumatra (Aceh, Simeulue, Padang) from an ecological perspective. Although Sumatra is geologically prone to earthquakes and tectonic activities due to its location on the Pacific Ring of Fire, hydrometeorological disasters such as floods and landslides are exacerbated by human actions, including deforestation, watershed degradation, and uncontrolled land conversion. This research employs a qualitative-descriptive approach using library research and a theological-reflective method. Primary sources include Sacred Scripture, Church documents (Laudato Si', Gaudium et Spes, General Directory for Catechesis), and relevant ecological theology literature. The findings indicate that natural disasters in Sumatra can be interpreted as "signs of the times" revealing both ecological and moral crises. Disasters are not divine punishment but consequences of humanity's misuse of freedom in managing creation. Ecological conversion is urgently needed at personal, social, and structural levels. Within the catechetical framework, disaster experiences become "texts of life" that guide the faithful toward mature faith expressed in lifestyle changes, solidarity, and responsibility for our common home.

Early marriage is a social and legal issue that still frequently occurs in Indonesia and has significant impacts on health, education, and socio-economic aspects. Although the minimum age for marriage has been regulated under Undang-Undang Nomor 16 Tahun 2019 tentang Perkawinan, the practice of early marriage remains prevalent due to low legal awareness, as well as economic, cultural, and social environmental factors. This community service activity aims to increase adolescents’ understanding and legal awareness regarding the impacts and prevention of early marriage. The method used is legal counseling with an educative and participatory approach targeting adolescents aged 15–18 years. The results indicate a significant improvement in participants’ understanding of legal regulations, the negative impacts of early marriage, and the importance of delaying marriage age. Furthermore, there is a positive change in participants’ attitudes, with a greater focus on education and future planning. Therefore, legal counseling proves to be an effective preventive effort in reducing the rate of early marriage among adolescents.

Low-rank coal generally has a high moisture content, which results in a low calorific value and suboptimal quality for utilization as an energy source. One method that can be applied to improve coal quality is the Upgrading Brown Coal (UBC) process, which functions to reduce moisture content and increase fixed carbon value. This study aims to analyze the effect of heating time and the ratio of used oil composition on improving coal quality based on proximate parameters. The research method includes collecting coal samples from four locations in Samarinda and its surrounding areas, namely SMAN 1 Samarinda, Bhineka Street, Palaran Stadium, and Tani Bakti Village. The samples were analyzed using proximate analysis, including inherent moisture (IM), ash content (AC), volatile matter (VM), and fixed carbon (FC), both before and after the UBC process. The upgrading process was carried out with variations in heating time and used oil composition as a coating medium to enhance coal stability and prevent moisture reabsorption. The final results of the upgrading process showed the best values of inherent moisture at 13.64%, ash content at 4.66%, volatile matter at 55.06%, and fixed carbon at 44.94%. The results indicate that the UBC process is capable of reducing inherent moisture and increasing fixed carbon, thereby improving coal quality. Variations in heating time and used oil composition have a significant effect on changes in proximate parameters. Longer heating time and an appropriate ratio of used oil composition result in a more optimal improvement in coal quality.

Marriage is a very strong contract (mistaqan ghalidan) to obey Allah's commands and carrying it out is an act of worship. The goal is to realize a household life that is sakinah, mawaddah, and rahmah. In the realization of a household with the bonds of marriage there are components that cover it, both in terms of regulations and legal concepts. Basically, a marriage agreement is a form of protection or protection if in the future there are things that are not desired by both parties such as death, divorce or bankruptcy, the legal basis regarding the marriage agreement itself has been regulated in the Compilation of Islamic Law and the Marriage Law Number 1 of 1974 and the Constitutional Court Decision No. 69 / PUU-XII / 2015, After the birth of the Constitutional Court Decision Number 69 / PUU / XII / 2015, the marriage agreement has changed both in terms of the time of creation and the institution that has the authority to ratify the marriage agreement.

This study aims to analyze the factors that influence the residential spatial system of the Marori and Mengge ethnic groups in Wasur Village, Merauke, South Papua, in the context of their involvement in the eucalyptus oil industry as a leading tourism product of Wasur National Park. A rationalistic qualitative approach is used with the main theory of behavioral setting to examine the relationship between behavior, local culture, and spatial structure. The results of the study indicate that houses not only function as domestic spaces, but also as places for the production of eucalyptus oil, especially at the packaging stage. The overlapping use of space causes space invasion, changes in function, and the emergence of high spatial flexibility. The space of the house undergoes a temporal functional transformation, adjusting to the intensity of economic activities and cultural rituals of the community. Private, semi-public, and spiritual spaces experience shifting boundaries, which have an impact on social relationship patterns and living comfort. This study also found that social structure, customary values (Boan/marga), and division of customary areas play an important role in the formation of the spatial system. These findings are expected to be an important contribution to the development of residential architecture based on behavior and local wisdom, as well as community-based conservation area management. This study also highlights the urgency of preserving the culture and existence of indigenous tribes amidst the current of modernization and the threat of extinction.

This study addresses the limited integration of environmental education, Islamic values, and creative learning practices in existing pedagogical models. It proposes an eco-friendly Islamic calligraphy approach as an innovative medium for recycling-based learning that promotes both ecological awareness and spiritual development. The study adopts a Participatory Action Research (PAR) design involving 22 students from diverse educational levels at Sanggar Bimbingan Bintang Sembilan. Data were collected through structured observations, semi-structured interviews, and documentation, and analyzed using an iterative qualitative framework to identify changes in students’ cognitive, affective, and behavioral domains. The findings indicate that students initially exhibited low environmental awareness, minimal engagement, and limited ability to utilize recyclable materials creatively. Following the intervention, there was a substantial increase in active participation, creative output, and conceptual understanding of environmental sustainability. Students also demonstrated observable behavioral shifts, particularly in waste reuse practices and environmental responsibility. In addition, the incorporation of Islamic values reinforced ethical awareness and strengthened students’ sense of stewardship toward the environment. This study contributes to the advancement of interdisciplinary learning by offering a contextual and practice-oriented model that integrates environmental education, religious values, and art-based pedagogy. The proposed approach not only enhances student engagement but also fosters holistic learning outcomes, making it a viable alternative to conventional instructional methods in sustainability education.

The accelerating global ecological crisis, manifested in deforestation, biodiversity collapse, and extreme climate change, fundamentally reflects a deep-rooted moral and spiritual deterioration within modern humanity. Islamic Religious Education (PAI) holds a unique strategic position to address this crisis by systematically integrating naturalistic intelligence, the eighth dimension of Howard Gardner's Multiple Intelligences theory, into the character formation process of students. This qualitative library research employs content analysis and conceptual analysis techniques applied to relevant primary and secondary academic sources published between 2019 and 2026. The study pursues three objectives: (1) to examine the conceptual and theological foundations of naturalistic intelligence within the Islamic educational framework; (2) to identify the reciprocal relationship patterns between naturalistic intelligence and the formation of religious-ecological character in students; and (3) to formulate integrative Islamic education management strategies for optimizing naturalistic intelligence. Findings reveal that naturalistic intelligence possesses robust theological grounding in Islamic tradition, anchored in the concepts of tafakkur, ayat kauniyah, khalifatullah fil ardh, and scientia sacra, none of which are peripheral but rather central to the Islamic worldview. The relationship between naturalistic intelligence and religious-ecological character is bidirectional and mutually reinforcing, operating through three sequential pathways: from naturalistic intelligence to theological consciousness, from theological consciousness to intrinsic ecological motivation, and from intrinsic motivation to consistent religious-ecological behavior. Islamic education management can optimize naturalistic intelligence development through four strategic pillars: reconstruction of the PAI curriculum based on ayat kauniyah, development of innovative eco-theological pedagogy, construction of an eco-conscious school culture, and strengthening of school-family-community partnerships. This study advances the concept of "Spiritual Eco-Literacy" as an original paradigmatic contribution to 21st-century Islamic education.

Heating, Ventilating, and Air Conditioning (HVAC) systems often suffer from significant energy wastage due to their inability to adapt to real-time environmental changes, leading to high operational costs. Although Proportional-Integral-Derivative (PID) controllers are widely used for their simplicity and reliability, they struggle to handle the complex dynamics of modern environments, requiring advanced optimization to enhance efficiency. This study aims to optimize PID controllers by integrating the Queen Honey Bee Migration (QHBM) algorithm to improve HVAC performance, energy efficiency, and adaptability. The research method employs an experimental approach that compares the performance of conventional PID controllers with PID controllers optimized using the QHBM algorithm under dynamic environmental conditions. The results show that the PID-QHBM system significantly outperforms the conventional PID system, achieving a rise time of 0.2649 seconds and a settling time of 1.6874 seconds with an almost negligible steady-state error of 9.4991e-08. Although it experiences a slight overshoot of 16.3810%, the system stabilizes quickly and maintains the target temperature efficiently. In contrast, the conventional PID controller exhibits slower response characteristics, with a rise time of 1.3730 seconds, a settling time of 2.5144 seconds, and a larger steady-state error of 0.0361. This study demonstrates that integrating the QHBM algorithm into PID controllers provides a more effective solution for real-time temperature control, offering substantial improvements in energy efficiency and system performance. The findings contribute to advancing intelligent HVAC control systems that can better adapt to environmental variations while minimizing operational costs.

Digital transformation has brought fundamental changes to the structure and dynamics of modern industrial economics. Technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and big data not only modify production and distribution processes but also revolutionize marketing strategies and patterns of industrial competition. This study is motivated by the need to understand how digital marketing transformation influences the development of competitive advantage through changes in digital market structure from an industrial economics perspective. In this context, digital marketing functions as a strategic instrument that integrates technology, data, and consumer behavior into market mechanisms. The analysis shows that digitalization creates a network-based market structure characterized by the concentration of economic power in major digital platforms and dominance in data control. This structure affects the intensity of competition, the direction of innovation, and patterns of industry differentiation. Digital marketing transformation enhances efficiency, expands market access, and lowers entry barriers for new players, yet it also creates competitive imbalances due to the dominance of large platforms.Through a digital Structure–Conduct–Performance (SCP) approach, the study finds that market structure acts as an intermediary variable that channels the impact of digitalization on competitive advantage. Digitalization significantly promotes industrial efficiency, innovation, and profitability. Proposed strategic solutions include strengthening digital literacy, developing adaptive regulations, and fostering cross-sector collaboration to create an inclusive, competitive, and sustainable digital industrial ecosystem

This study aims to examine the differences in stock prices before and after the Palestine-Israel ceasefire event in fast-food restaurant companies,  Pizza Hut and KFC. International-scale events may influence investor perceptions, as reflected in stock price movements in the capital market. This study employs a comparative quantitative approach using stock price data collected over 30 days before and 30 days after the ceasefire event. The analyzed data consist of secondary data processed through descriptive statistics, normality tests, and hypothesis testing. The findings indicate that the average stock price of PZZA increased after the event, whereas FAST experienced a decline in its average stock price. These results reveal differences in stock prices between the periods before and after the ceasefire event in both companies. The findings further suggest that geopolitical events are associated with changes in stock prices in the fast-food restaurant industry, although market responses differ across companies. Therefore, future studies are recommended to expand the scope of research objects and extend the observation period to obtain a more comprehensive understanding of market responses to international events.

Digital transformation in the tax sector is a strategy of the Direktorat Jendral Pajak (DJP) to improve the quality of service and taxpayer compliance. One form of this transformation is the implementation of the Coretax system as an integrated tax administration system that replaces the DJP Online system. This system change poses adaptation challenges for taxpayers, particularly in reporting Annual Tax Returns, which has the potential to affect the accuracy of tax payments. This study aims to analyze the optimization of the transition of Annual Tax Return reporting through the Coretax system on the accuracy of individual taxpayer payments at the North Sidoarjo Tax Office (KPP Pratama). The research method used is descriptive qualitative with data collection techniques such as observation of the Annual Tax Return reporting assistance process, documentation, and interviews with three taxpayers. The results show that the Coretax system is able to improve the accuracy of tax filing through data integration and automatic validation, thereby encouraging the accuracy of the amount and timeliness of tax payments. However, technical system constraints and limitations in taxpayer digital literacy were still encountered during the transition period. Assistance from tax officers and tax volunteers proved to be instrumental in helping taxpayers adapt to the Coretax system. This study concludes that optimizing the transition of the Coretax system requires a combination of system improvements and strengthening taxpayer education to achieve sustainable accuracy of tax payments.

Providing passive ROM to the extremities can help improve blood circulation, improve respiratory function, and support the recovery of consciousness as assessed using the Aldrete Score. The purpose of this study was to determine the effect of providing early passive ROM mobilization of the extremities on changes in the Aldrete score in patients after general anesthesia. This study used a pre-experimental design with a one-group pretest-posttest approach. The study sample consisted of 57 respondents. The intervention provided was early passive ROM mobilization. The Aldrete score was measured before and after the intervention. Data analysis used the Wilcoxon signed rank test with a significance level of α = 0.05. The results showed that the average Aldrete score before the intervention was 5.89 and after the intervention increased to 9.26. The results of the statistical test showed a p value = 0.0001 (p <0.05), which means that there is a significant effect of providing early passive ROM mobilization of the extremities on increasing the Aldrete score after general anesthesia. From this study, it can be concluded that there is an effect of providing early passive ROM mobilization of the extremities on increasing the Aldrete score after general anesthesia.

Children with Autism Spectrum Disorder (ASD) face unique challenges in building attachment relationships, due to ASD children experiencing impairments in communication, social interaction, and emotional regulation. This study aims to identify effective intervention strategies to improve the quality of attachment between parents and children with ASD through a Systematic Literature Review (SLR) approach. The review findings indicate that several interventions have proven effective in enhancing attachment between parents or primary caregivers and children with ASD, including the following interventions: DIR/Floortime, Focused Playtime Intervention (FPI), Parent-Child Interaction Therapy (PCIT), Circle of Security (COS), Positive Behavior Support (PBS), play training, massage therapy, and psychoeducation. The results of these interventions show that changes occur before and after the intervention, including strengthening two-way communication, increasing parental sensitivity, and improving the child's emotional responses. These findings have practical implications for parents, educators, and therapists in designing attachment-based approaches to support the social and emotional development of children with ASD. Responsive and supportive designing attachment-based approaches to support the social and emotional development of children with ASD. Responsive and supportive relationship-based interventions can build secure attachments between children with ASD and their parents and serve as an important reference in attachment-based parenting and therapy practices.

This study aims to analyze the impact of the USD/CNY exchange rate and the Federal Reserve interest rate on the stock returns of Volkswagen AG. Volkswagen AG is chosen as the object of analysis because it is a multinational corporation with significant exposure to the Chinese market, making it highly sensitive to fluctuations in global economic conditions, particularly exchange rate movements and monetary policy changes. The study adopts a quantitative research approach using multiple linear regression analysis to examine the relationships between variables. The data used are monthly secondary data covering the period from 2017 to 2023, resulting in 84 observations. The dependent variable in this study is Volkswagen AG stock returns, while the independent variables consist of the USD/CNY exchange rate and the Federal Funds Rate. The empirical results show that the USD/CNY exchange rate has a negative and statistically significant effect on Volkswagen AG stock returns, indicating that currency depreciation or appreciation plays a crucial role in influencing investor sentiment and firm valuation. In contrast, the Federal Funds Rate does not show a statistically significant effect on stock returns during the observed period. However, the simultaneous test indicates that both variables jointly have a significant influence on Volkswagen AG stock returns. Overall, the findings suggest that exchange rate risk is more dominant than U.S. monetary policy in affecting the stock performance of Volkswagen AG over the study period.

Digital transformation in the public sector encourages civil servants to utilize technology not only for administrative purposes but also to improve efficiency, accuracy, and work performance. This study examines the influence of Intelligent Learning-Based Training and Digital Training Components on the Digital Productivity of civil servants at the Bureau of Economic Affairs of the Regional Secretariat of Lampung Province, with Adaptive Competence serving as a mediating variable. A quantitative approach with a non-experimental survey design was applied, and data were collected through structured questionnaires distributed to employees engaged in digital-based work activities. The data were analyzed using structural model testing procedures. The findings reveal that Intelligent Learning-Based Training does not significantly influence Adaptive Competence or Digital Productivity. Conversely, Digital Training Components positively and significantly affect both Adaptive Competence and Digital Productivity. Adaptive Competence also has a positive impact on Digital Productivity and mediates the relationship between Digital Training Components and Digital Productivity. However, Adaptive Competence does not mediate the relationship between Intelligent Learning-Based Training and Digital Productivity. These results indicate that civil servants’ digital productivity is more effectively improved through practical, relevant, accessible, and well-evaluated digital training programs than through intelligent learning systems alone. Therefore, public institutions are encouraged to develop digital training initiatives that align with employees’ daily work demands while strengthening their adaptive competence in responding to technological changes.

The routine prayer recitation activity with teenagers in Jatikalang Village, Krian, Sidoarjo, essentially arose from the need for moral development among teenagers amidst today's increasingly complex and externally influenced lives. Through this activity, it is hoped that teenagers can become closer to religious values ​​without feeling patronized, as the activities are simple and relevant to their daily lives. Furthermore, a sense of community among teenagers is fostered, becoming more than just a form of worship but also a positive gathering space. The implementation itself uses an Asset-Based Community Development (ABCD) approach, emphasizing existing community potential, such as the role of administrators, youth involvement, and available village facilities. The activity is relatively simple, starting with an opening and reciting prayers, rowi Diba' (the prayer of the Prophet), mahalul qiyam (the prayer of the Prophet), and closing with a short sermon (kultum) usually containing light but impactful messages. These activities are beginning to show changes: teenagers are becoming more active, a sense of togetherness is growing, and good habits such as discipline, mutual respect, and responsibility are gradually emerging. Furthermore, this activity serves as an alternative to prevent teenagers from getting caught up in less beneficial activities. There are still challenges, particularly with fluctuating attendance and the strong influence of the external environment. However, if maintained and developed consistently, this activity has great potential to become a platform for social and spiritual development for youth. Overall, this sholawat routine is quite effective in developing religious character and strengthening social ties within the community.
