The development of social media has significant transformations in the communication strategies of retail companies, particularly in building relationships with customers digitally. In the context of increasingly intense competition, social media no longer functions merely as a promotional channel, but also an interactive space to shape engagement, brand perception, and long-term relationships with customers. TIP TOP Supermarket, as one of the modern retail players in Indonesia, utilizes Instagram as its primary digital communication channel to reach audiences, convey brand values, and build customer engagement. The majority of TIP TOP Supermarket’s customers do not yet possess high levels of digital awareness, resulting in limited engagement with TIP TOP’s activations on Instagram. TIP TOP has not yet implemented a strategic approach in managing its Instagram. This condition constitutes a challenge in Instagram management. This study aims to analyze the stages of research and diagnosis, objective, strategies, tactics, implementation, and reporting-evaluation carried out by TIP TOP Supermarket in building customer engagement. The research employs a descriptive qualitative approach within a positivist paradigm. Data were collected through in-depth interviews with seven key informants from the Marketing and Communications Division, observations, and online documentation. The findings indicate that the management of TIP TOP Supermarket’s Instagram has gone through all stages of the ROSTIR, although several aspects have not yet been fulfilled. The conclusion emphasizes the importance of building a brand identity with consistent characteristics. This study recommends the establishment of a digital community on Instagram and the adoption of a responsive approach toward customers.

This study aims to analyze the implementation of the Independent Curriculum in third-grade students at Al-Munawarah Elementary School, Sentani, Jayapura Regency. Using a qualitative approach with data collection techniques through observation, interviews, and documentation, this study evaluated three main aspects: planning, implementation, and evaluation of learning. The results showed that during the planning stage, teachers developed teaching modules that referred to Learning Outcomes (CP) and prepared assessment instruments in the form of projects and prompt questions. During the implementation stage, teachers implemented an inquiry-based learning model to encourage student engagement and utilized various media, from printed books to digital devices, which positively impacted student engagement in class. During the evaluation stage, teachers used cultural project assessments and Student Worksheets (LKPD), accompanied by positive feedback to motivate students. Although implementation generally proceeded according to the curriculum framework, obstacles were still encountered in the application of differentiated learning because teachers tended to use lecture methods and generalize the abilities of all students. Therefore, continuous improvement is needed so that learning planning can be more aligned with the characteristics and individual needs of each student.

This study aims to analyze the effectiveness of the application of direct and indirect methods in teaching English, specifically the topic of "Telling Time," at MTs Al-Amiriyyah through microteaching practice. This research employs a descriptive qualitative approach with data collection techniques including observation, interviews, and documentation. The research subjects consist of an English teacher and the students of class VIII A. The data were thematically analyzed to identify significant patterns in the teaching process. The findings indicate that the direct method is effective in building students' foundational understanding of time concepts, as it emphasizes explicit and concrete use of the target language and allows teachers to easily assess students' comprehension through drilling. On the other hand, the indirect method proved to enhance students’ ability to use English more naturally through contextual activities such as role play and daily schedule games. Moreover, students with kinesthetic learning styles responded more positively to the indirect method, as it enables them to learn through physical activity and direct participation. These findings suggest that a combination of both methods yields optimal results: the direct method is effective for the initial stage of concept acquisition, while the indirect method supports the development of communicative skills in a functional and enjoyable manner, aligning with students' characteristics.

This community service activity aims to improve the knowledge and skills of Aisyiyah Kindergarten teachers in developing their potential and professional competence related to the implementation of inclusive education. Inclusive education requires teachers to have a sufficient understanding of the characteristics of children with special needs (ABK) and the ability to manage diverse students in the classroom. This activity was implemented in the form of systematically designed and applicable workshops and seminars. The training materials covered four main components: recognizing the characteristics of children with special needs, the concepts and principles of inclusive education, curriculum accommodations and assessments in inclusive classrooms, and techniques for identifying and evaluating learning for children with special needs. The results of the activity showed a significant increase in teachers' understanding and skills in managing inclusive classrooms, particularly in developing Individual Learning Plans (ILPs) tailored to the needs of the children. Teachers also became more confident in implementing adaptive and responsive learning strategies to the diversity of students. However, the sustainability of the program still faces several challenges, including limited supporting resources and minimal parental involvement and support. Therefore, ongoing synergy between schools, parents, and other stakeholders is needed to support the optimal implementation of inclusive education.

The development of lanthanum-doped barium hexaferrite materials has attracted considerable attention in the field of functional materials, particularly as electromagnetic wave absorbers. This literature review aims to analyze advances in synthesis methods, structural characteristics, magnetic properties, and electromagnetic absorption performance of lanthanum-doped barium hexaferrite reported in various studies. Synthesis techniques such as sol–gel, coprecipitation, solid-state reaction, and hydrothermal methods are compared to evaluate their effects on crystallite size, morphology, and phase purity. Lanthanum doping is known to modify lattice parameters, reduce coercivity, and enhance complex permittivity and permeability, which play crucial roles in absorption mechanisms. Furthermore, variations in dopant concentration significantly influence reflection loss values and effective absorption bandwidth. The reviewed literature indicates that optimization of composition and synthesis routes can produce materials with high absorption capability, good stability, and strong potential for application in electromagnetic interference mitigation devices. This review is expected to serve as a conceptual reference for future development of lanthanum-doped barium hexaferrite–based electromagnetic wave absorbing materials. The comparative approach also highlights research challenges, industrial application opportunities, and future research directions relevant to the evolving demands of modern communication and defense technologies at both national and global levels.

The increasing demand for paper has led to a shortage of wood-based raw materials, thus requiring environmentally friendly alternatives. This study aims to analyze the physical, mechanical, and morphological characteristics of paper made from cassava peels (Manihot esculenta Crantz) and oil palm fruit fibers (Elaeis guineensis Jacq.) as eco-friendly paper raw materials. The research method involved pulp preparation through delignification using 3.5% HNO₃ and 3% NaOH, bleaching with 10% H₂O₂, paper sheet formation with varying compositions (A = 70:30, B = 50:50, C = 30:70, D = 10:90), followed by grammage testing and tensile strain testing. The results showed that the grammage values ranged between 96.3–99.7 g/m², while tensile strain ranged between 2.6–4.4%. The study concluded that the best composition was found in sample C (30% cassava peel : 70% palm fiber) with a grammage of 98.5 g/m² and tensile strain of 3.2%. The implication of this study is that cassava peel and palm fiber waste have the potential to serve as alternative paper raw materials that meet the quality standards of A-grade printing paper (SNI 7274:2008), while also supporting the reduction of dependence on wood.

This research extends the previous work of Tsaqila, Winiarti, and Widaningrum (2024), who applied the Complex Proportional Assessment (COPRAS) method within a decision support system for supermarket branch location selection. Unlike the prior study, which focused on Ponorogo through a web-based framework, this study expands the implementation of COPRAS to the Medan Area, Medan Kota, Medan Polonia, dan Medan Maimun districts, adapting it to local urban, social, and economic characteristics. The main objective is to identify the most strategic site for a new supermarket by analyzing multiple criteria, including land cost, population density, accessibility, safety, cleanliness, and disaster risk. Data were collected from both field surveys and official government publications. The findings reveal that the COPRAS method provides reliable and objective assessments among the evaluated alternatives, with Medan Area emerging as the most suitable location for supermarket development. Overall, this study broadens the practical scope of the COPRAS method in a different regional context and reinforces its reliability and adaptability as a multi-criteria decision-making tool in the modern retail industry.

The development of the Industrial Revolution 4.0 to the Society 5.0 era presents new challenges for education, including Islamic Religious Education (PAI). PAI is required not only to transfer religious knowledge but also to shape character, morality, and 21st-century competencies. This study aims to examine the philosophical foundations, characteristics, and application of PAI learning models to ensure their relevance in modern education. The research employed a qualitative approach with a library research design, involving the exploration of primary and secondary literature, critical reading, systematic note-taking, and content analysis validated through triangulation of classical and contemporary sources. The findings indicate that PAI learning models are conceptual, theoretical, systematic, and rooted in religious, philosophical, psychological, and sociological foundations. Four main models behavioristic, information processing, social, and humanistic each have strengths and limitations, yet their integration is relevant to forming insan kamil, a holistic human being balanced in cognitive, affective, psychomotor, spiritual, and social aspects. Therefore, developing PAI learning models based on Islamic philosophy and adaptive to technological advancements is a strategic necessity to face global challenges.

This study aims to analyze the process of processing fruit peel waste from juice traders into eco-enzymes as an effort to reduce environmental pollution. The research uses qualitative descriptive methods through direct observation, documentation, and literature studies. Fruit peel waste is fermented at a ratio of 1:3:10 (molasses : fruit waste : water) for three months under anaerobic conditions. The fermentation results show good eco-enzyme characteristics, characterized by a pH of 3, a fresh sour aroma, and a brownish color as an indicator of fermentation success. These findings show that the process of processing eco-enzymes from fruit peel waste can be done simply, cheaply, and environmentally friendly. In addition, the use of eco-enzymes has the potential to reduce the volume of organic waste disposed of in landfills and reduce water and soil pollution. The resulting eco-enzyme also has potential applications as natural cleaners, liquid fertilizers, and odor controllers. Thus, the treatment of fruit peel waste not only supports sustainable environmental management practices, but also encourages the implementation of the circular economy as well as community empowerment ecologically and economically.

Early English mastery is a long-term educational investment that should be supported by instructional approaches aligned with children’s developmental characteristics. This community service program aimed to systematically implement the *English Through Play* approach, enhance English learning interest, and create positive learning experiences for children aged 4–6 years at Samantha English Course. The program was conducted participatorily through preparation, implementation, and evaluation stages over eight weeks. The *English Through Play* approach was applied through various activities, including action songs, flashcard games, storytelling with gestures, and simple role play. Evaluation was carried out descriptively through observation of participation, verbal responses, children’s expressions, and simple oral tests to measure basic vocabulary mastery. The results showed that more than 80% of the children were actively engaged during the learning sessions. Approximately 70–85% demonstrated increased learning interest, as reflected in their enthusiasm, verbal participation, and positive responses to English instructions. In addition, most children were able to recognize and pronounce 5–10 basic vocabulary items based on the learning themes and perform simple self-introductions. The program also produced a play-based learning guide that can be sustainably implemented by the partner institution. In conclusion, the *English Through Play* approach proved effective in enhancing young learners’ interest and participation in early English learning. This model can serve as a practical and replicable alternative for similar non-formal educational institutions.

This study aims to examine and analyze the influence of auditor ethics, auditor competence, and audit risk on audit quality, with audit fees serving as a mediating variable. This research employs a quantitative associative approach with a casual explanatory design. Data were collected through a questionnaire survey administered to external auditors working at Public Accounting Firms (PAFs) in Surabaya, with a population of 55 firms. The sampling technique used was convenience sampling, resulting in 42 auditors as respondents with the characteristic of having worked at Public Accounting Firms in Surabaya for at least one year as of 2025. Data analysis was conducted using the Partial Least Square (PLS) method assisted by SmartPLS 4.0 software. The results indicate that auditor competence and audit risk have a positive and significant effect on audit fees, while auditor ethics does not have a significant effect. Furthermore, auditor ethics has a positive and significant effect on audit quality, whereas auditor competence, audit risk, and audit fees do not show a significant effect. In addition, audit fees are not proven to function as a mediating variable and therefore are unable to mediate the effects of auditor ethics, auditor competence, and audit risk on audit quality.

This study discusses the comparison of traditional and modern management accounting methods with the aim of analyzing the characteristics, advantages, and disadvantages of each method and providing practical guidance for corporate decision-making. The research method uses a literature review approach, collecting and synthesizing various recent studies related to Activity Based Costing (ABC), Target Costing, and Balanced Scorecard (BSC), and comparing them with traditional methods such as job order costing and process costing. The analysis results show that traditional methods are simpler and easier to implement, but less accurate in calculating costs and less relevant for strategic decision-making. In contrast, modern methods offer higher accuracy through detailed cost allocation, comprehensive performance monitoring, and data-based decision-making support, although they require greater implementation complexity and resources. This study concludes that the choice of method must be adjusted to the characteristics of the company and the complexity of business activities, so as to optimally improve cost efficiency and profitability.

Welfare for the poor is the most important topic in improving citizens. Islam as Ad-diin has offered several teachings for humans that apply universally with two dimensional characteristics, namely happiness and well-being in life in this world and in the hereafter. In the concept of the modern world, welfare is a condition where a person can fulfill basic needs, be it the need for food, clothing, shelter, clean drinking water as well as the opportunity to continue education and have adequate work that can support the quality of life so as to have a social status that leads to the same social status as other citizens. ZIS as an extension of the government in helping the needs of the poor with the aim of improving the welfare of the community who initially as zakat recipients turned into zakat givers, so that later the funds used will be evenly distributed and felt by the wider community. as well as purifying assets that may be accidentally mixed with assets that are forbidden for consumption. The urgency of ZIS in Sidowungu is one of the main elements of effective and efficient zakat management in order to realize the welfare of the community. As for the discussion of this article about the welfare pattern for the poor as the process of distributing ZIS funds in Sidowungu Village. The method used in this article is a quantitative approach. The subjects of this study were 165 poor people in Sidowungu Village, while the sample size was 65 poor people using probability sampling. The results of the study, processed using the PASW SPSS 23 for Windows program, showed that partial test results for H0 were rejected and H1 was accepted if the calculated t value was greater than the table t value or the sig value was less than 0.05. This means that the distribution of funds partially affected the welfare of the poor in Sidowungu Village. The magnitude of the influence between variables can be seen from the coefficient of determination of 0.079, meaning that 79.0% of the welfare of the poor in Sidowungu Village was influenced by the distribution of ZIS funds, while the remaining 21.0% was influenced by other variables not included in this study.

The increasing number of children facing the law in Indonesia indicates that the repressive legal approach has not been fully effective in addressing juvenile crime. Children, as subjects of law, have social and psychological characteristics that differ from adults, so law enforcement against them must consider humanitarian and educational aspects. This research aims to analyze the factors causing children to commit criminal acts and formulate a model for addressing them based on developing a legal culture rooted in Pancasila values. This research employs a normative juridical method with conceptual and legislative approaches, and analyzes data qualitatively thru literature review and positive legal norms. The research findings indicate that the causes of children committing criminal acts are multidimensional, encompassing family factors, social environment, education, economics, and psychological factors. Therefore, mitigation efforts cannot be done partially, but must be thru a preventive, educational, and restorative approach. This research offers a model for overcoming challenges thru the development of a legal culture based on five main pillars: family, education, society, the state, and the legal system. This model emphasizes the importance of synergy between law enforcement and moral development in accordance with the values of Divinity, Humanity, Unity, Deliberation, and Social Justice. Thus, the development of Pancasila legal culture is expected to realize a child criminal justice system that is humanistic, substantively just, and oriented toward social rehabilitation in accordance with the legal ideals of a Pancasila state of law.

Per capita expenditure is an important indicator of household welfare because it reflects the economic capacity and consumption patterns of the community, as explained in Engel's Law. In regions with diverse geographical characteristics such as Papua Province, spatial analysis is needed to understand the variations in expenditure between districts/cities and the differences between urban and rural areas. This study aims to analyze the spatial distribution of per capita expenditure percentages for food and non-food items in nine districts/cities in Papua Province during the 2022–2024 period. The research data was sourced from the National Socioeconomic Survey (Susenas). The methods used included quantile-based choropleth mapping using QGIS, attribute data merging through table joins, and Pearson's correlation test to evaluate the consistency of spending patterns between years. The analysis results show that food and non-food spending patterns were relatively stable during the observation period with high correlation values (r = 0,85–0,93), although spatial variations between regions were still apparent. Mamberamo Raya Regency consistently had the highest proportion of food spending (>68%), while Jayapura City showed the lowest proportion. These findings indicate spatial disparities related to urbanization levels and economic access. Spatial visualization proved effective in revealing regional disparity patterns that were not fully apparent through conventional statistical tables and has the potential to support the formulation of more evidence-based regional development policies.  

Flooding is one of the most recurrent natural disasters in Central Java Province, particularly during the rainy season. Diverse geographical characteristics, high rainfall intensity, and rapid urban development contribute to the region’s high vulnerability to flood hazards. According to the Central Java Statistics Agency, a total of 414 flood events and 407,784 affected victims were recorded between 2019 and 2021. This study aims to develop a web-based Geographic Information System (GIS) capable of mapping the spatial distribution and impact levels of floods across Central Java. The methodology includes collecting flood event data from the Central Java Statistics Agency, processing spatial data such as administrative boundary shapefiles, performing attribute integration between spatial and non-spatial datasets, and creating thematic maps using QGIS. The visualization outputs were exported into an interactive web format using the qgis2web plugin and subsequently integrated into a website developed with HTML, CSS, and JavaScript. The results show that the GIS system successfully visualizes flood-prone areas, identifies regions with high flood intensity, and enables users to explore detailed information through interactive digital maps. Additional website features—such as historical flood data, statistical summaries, and descriptive impact indicators—enhance the system's usefulness for disaster analysis. This study demonstrates the crucial role of GIS in supporting disaster mitigation, spatial planning, and policy evaluation related to flood management. Future research is recommended to incorporate more recent datasets and additional non-spatial variables such as rainfall intensity and floodwater depth to improve the system’s analytical accuracy and comprehensiveness.

Increasing in energy demand and limited fossil fuel reserves have driven the use of environmentally friendly alternative energy sources. This study aims to analyze the effect of pyrolysis temperature variations on the quality of biopellets made from bagasse and coffee husks. The materials were prepared in a 50:50 ratio with the addition of 15% tapioca flour as a binder. The pyrolysis process was carried out at temperatures of 450°C, 500°C, and 550°C for 120 minutes in oxygen-free conditions. The biochar resulting from pyrolysis was formed into biopellets, which were then tested for proximate composition, calorific value, and combustion rate. The results showed that an increase in pyrolysis temperature had a significant effect on the characteristics of the biopellets. A temperature of 550°C produced the lowest moisture content (8.436%), the highest fixed carbon content (62.191%), the highest calorific value (6293 cal/g), and the highest combustion rate (0.05789 g/sec). Conversely, ash content increased with rising temperature, while volatile matter content decreased. Thus, the best biopellets were obtained at a temperature of 550°C. This study confirms the potential of bagasse and coffee husks as raw materials for biopellets through pyrolysis temperature optimization to support the development of sustainable biomass energy.

Constructivism learning theory places learners as active subjects in constructing knowledge through learning experiences, social interactions, and reflection on their surroundings. This approach views learning not as a passive process of receiving information, but as an active process of constructing meaning based on the prior knowledge possessed by learners. This paper aims to comprehensively examine the development and definition of constructivist learning theory, its main principles and characteristics, and its implications in the learning process, particularly in the context of primary education. The writing method used is a literature study by analyzing various literature sources in the form of textbooks, scientific journal articles, and other relevant references related to constructivism theory. The results of the study show that constructivist learning emphasizes learner-centered learning, where knowledge is not transferred directly by the teacher but is constructed through a process of assimilation and accommodation. In this approach, teachers act as facilitators who design a conducive learning environment so that students are able to build understanding independently and through social interaction. The application of constructivist learning has been proven to encourage the development of critical thinking, problem solving, cooperation, and meaningful learning. Therefore, constructivist learning theory is relevant to be applied in modern learning as an effort to improve the quality of the learning process and outcomes of students.
