Traditional association rule analysis is effective at uncovering co-purchase patterns but fails to provide a global structural view of the market, which often results in fragmented and isolated insights. This study proposes a hybrid framework that integrates the Apriori algorithm with a Minimum Spanning Tree (MST) in order to validate and contextualize association rules within a single structural backbone. Transaction data from a retail store are transformed into a weighted, undirected product graph using an inverse-support function, and an MST is then extracted to represent the market backbone, while frequent itemsets and strong rules are obtained using Apriori. Experimental results on 236 multi-item transactions show that the MST backbone comprises 10 products and 9 fundamental links, with 66.67% of these links being confirmed by strong association rules, indicating a substantial coherence between statistical and structural evidence. The proposed model identifies 41 Apriori patterns that can be embedded in the MST and ranks them using a new metric, Structural Distance, which enables the categorization of Core Patterns, Bridge Patterns, and Complex Patterns according to their structural tightness. This hybrid perspective distinguishes dense, strategically meaningful bundles from anomalous but frequent combinations that are structurally peripheral, thereby offering a more holistic and actionable alternative to conventional Market Basket Analysis. The validated framework can support various applications, including store layout optimization, cross-selling strategies, and the design of path-based recommender systems, and it opens avenues for future extensions based on dynamic graphs and Graph Neural Networks.

This study aims to analyze the influence of Product Ingredients and Halal Certification on Consumer Purchase Intention toward udon products in Medan City. The research background is grounded in the increasing concern of Muslim consumers regarding the clarity of product composition and the legality of halal certification, particularly for foreign food products such as Japanese udon. The study employed a quantitative approach with a causal associative design, involving respondents who had purchased udon products. Primary data were collected through questionnaire distribution, and the analysis was conducted using multiple linear regression. The findings indicate that Product Ingredients have a positive and significant effect on Purchase Intention, with ingredient information emerging as the most dominant indicator because it provides certainty regarding product safety, quality, and halal compliance. Halal Certification was also found to significantly influence Purchase Intention, with the legality of the certifying institution being the most emphasized indicator, while detailed certification information received relatively lower attention. Simultaneously, both variables explained 68% of the variation in purchase intention, with referential intention being the highest indicator, demonstrating consumers’ tendency to recommend the product to others. These results highlight that transparency of ingredients and credible halal certification are crucial factors in shaping consumer purchase intention toward udon products. The study recommends that producers improve clarity of ingredient information, display official halal certification details, and offer product innovations to increase consumers’ exploratory intentions.

The production of breast milk is essential for promoting optimal growth and developmental outcomes in infants throughout the first six months of life. Nevertheless, several studies have indicated that some breastfeeding mothers face challenges in producing adequate milk, often influenced by nutritional status, psychological conditions, and environmental support. The katuk plant (Sauropus androgynus), a well-known local herb, has long been recognized for its potential as a natural galactagogue that can stimulate breast milk production. The innovation of processing katuk leaf extract into biscuits offers a more practical, convenient, and potentially acceptable alternative for daily consumption among the community. The present study aimed to examine the impact of katuk leaf biscuits on breast milk production among breastfeeding mothers within the jurisdiction of Kuta Baro Health Center, Aceh Besar District. A pre-experimental design utilizing a one-group pretest–posttest method was implemented, involving 20 breastfeeding mothers who fulfilled the established inclusion criteria. Data collection was carried out through the administration of questionnaires and by measuring breast milk volume using a calibrated measuring cup.The study findings indicated that before the intervention, most participants had relatively low breast milk production, averaging 69.1 ml. After a seven-day intervention, the mean breast milk volume showed a significant increase to 246.5 ml, with a p-value of 0.000 (p < 0.05), the findings indicate that katuk leaf biscuits exert a significant influence on increasing breast milk production. Overall, this study underscores the potential of locally sourced, herbal-based food innovations as an effective and sustainable approach to enhancing breast milk production and supporting the success of exclusive breastfeeding programs.

The phenomenon of masculine men has become a new strategy in the modern beauty product marketing industry. Changing social and cultural values about gender identity have led to the emergence of male images with soft, stylish, and aesthetic characteristics in various promotional campaigns. This study aims to analyze how the phenomenon of masculine men is used as a marketing communication strategy, as well as its impact on consumer perception. The method used is a literature study with a descriptive qualitative approach, which examines contemporary communication theory, gender theory, and modern marketing concepts. The findings suggest that the use of masculine male figures in beauty product advertising can expand market segmentation, attract cross-gender audiences, and create an inclusive brand image that aligns with current social trends. However, this strategy also raises debates about the limitations of masculinity and the social construction of beauty. Therefore, the phenomenon of masculine men can be understood as a form of adaptation of marketing communication to changes in cultural and gender values in contemporary society In addition, the findings of this study are expected to make a theoretical contribution to the study of marketing communication and gender studies, as well as become a practical reference for beauty industry players in designing promotional strategies that are sensitive to social dynamics, cultural values, and the increasingly diverse preferences of modern consumers.

This study examines and critically analyzes speaking tasks in Netzwerk Neu A1.1 (Chapters 1–6) by evaluating their alignment with principles of German as a Foreign Language (DaF), Task-Based Language Teaching (TBLT), and the Common European Framework of Reference for Languages (CEFR). Using qualitative content analysis, 26 speaking tasks were identified, coded, and categorized based on task type, CEFR communicative activity (spoken interaction or spoken production), interaction mode, and levels of learner output. The findings show that template-based tasks dominate the textbook, accounting for 69.2% of activities, while guided and free production tasks are relatively limited. Spoken interaction is the most prevalent communicative activity (76.9%), reflecting an emphasis on dialogic formats such as short exchanges and role plays. Although this design provides appropriate structural support for beginner learners, the limited use of open-ended and autonomous tasks may restrict the development of fluency, communicative flexibility, and strategic competence. Interviews with seven learners and two instructors reveal that while tasks are generally perceived as accessible and confidence-building, they are also considered repetitive and insufficiently authentic. The study underscores the need to balance structured support with opportunities for spontaneous language use in beginner DaF textbooks.

Customer satisfaction is a central issue in marketing management, as it plays a crucial role in determining customer loyalty amid increasingly intense business competition. A comprehensive understanding of the factors influencing customer satisfaction is essential not only for academics in strengthening marketing theory but also for practitioners in designing effective service and product strategies. This article aims to address two research questions: (1) what are the dominant factors influencing customer satisfaction, and (2) how does customer satisfaction relate to customer loyalty? The study employed a qualitative literature review method. The data consisted of scientific articles published between 2020 and 2025, accessed through Google Scholar and Publish or Perish (PoP) using the keyword “customer satisfaction.” From an initial selection of 30 articles, 27 were identified as relevant, and 5 core articles were further analyzed. The findings reveal three main themes: product and service quality as the dominant determinants of customer satisfaction; price, brand image, and promotion as supporting factors; and customer trust as an important mediating variable in building loyalty. This study concludes that customer satisfaction serves as a strategic link between service quality and customer loyalty. Future research is encouraged to explore the roles of digitalization, customer experience, and sustainability in shaping long-term customer satisfaction.

These findings suggest that Apple’s STP strategy has been effective in strengthening brand image among students; however, improvements are still needed, particularly in information delivery and service accessibility. This study is expected to provide practical insights for businesses and educational institutions in developing marketing strategies aligned with young consumer characteristics.

According to Sigmund Freud's psychoanalytic theory, mental disorders occur due to conflicts between the id, ego, and superego that give rise to anxiety and abnormal behavior. At the Pamardi Raharjo Banjarnegara Social Service House, this conflict is diverted through a skills guidance program that aims to improve the independence and quality of life of Beneficiaries (PM). The program includes training in doormat crafts, salted egg making, paving blocks, and flannel crafts, each of which is guided by a dedicated mentor and followed by a stabilized PM. The activity of making mats aims to train motor skills and social interaction and produce products with selling value. The making of salted eggs not only teaches production skills, but also fosters confidence and economic independence. Paving block activities are more focused on motor training and cooperation between PMs even though they are not yet worth selling. Meanwhile, flannel handicrafts guided by Mbak Retno became a new activity that provided space for expression and creativity. All of these activities are designed to distract PM's passive behavior and equip them with useful practical skills after leaving the orphanage. Thus, skills-based approaches have proven to be effective in supporting the overall rehabilitation and empowerment process of PM.

PT. Barito Bangun Nusantara is a company engaged in coal exploration and production activities, where the production is temporarily stored in a stockpile area before being processed or distributed. Stockpile management requires attention to several important factors, such as area design and stockpiling methods, so that storage runs effectively and does not cause a decrease in coal quality. This study was conducted on old and new stockpiles with the aim of analyzing the actual stockpiling conditions and providing technical recommendations regarding the ideal stockpile capacity and configuration. The research methods included field observation, primary and secondary data collection, and descriptive quantitative analysis. The results showed that both stockpiles experienced inefficiencies due to excess capacity. The actual tonnage reached 49,191.98 tons, exceeding the planned capacity of 35,000 tons, with a stockpile height reaching 9 m. This condition caused long stacking times and the FIFO system did not operate optimally. The study recommended an ideal stockpile capacity of 30,740.61 tons, with a maximum height of 8 m. The recommended angle of repose for the old stockpile is 30°, with a capacity of 11,542.19 tons, while for the new stockpile, it's 34°, with a capacity of 19,198.42 tons. This arrangement is expected to allow for a smoother unloading process and a more ideal stockpile.

One of the various salted egg products with smoking methods is smoked salted eggs which have a distinctive aroma and taste. This study aims to determine the effect of smoking and storage time  and its  interaction on  smoked salted  eggs  with on  physical  and  chemical  properties, total microbes as well. This research is experimental by using ducks eggs and a mixture of coconut shells and fibers, and rice husks as smoke fuel. The experimental design used is Randomized Complete Block Design (RCBD) with a 3x5 factorial pattern. As the first factor (P) is the smoking time which consists of P0= 0 hours, P1= 12 hours, P2= 15 hours while the second factor (H) is the storage time which consists of H0= 0 days, H1=7 days, H2= 14 days, H3= 21 days, and H4= 28 days. The variables observed were egg weight, albumen and yolk pH, moisture content, protein, and total microbial colony of smoked salted eggs. The results of the study were that the smoking time of 15 hours resulted in the lowest weight of smoked salted eggs (56.13g), while the storage time decreased the pH of albumen. Smoked salted duck eggs have a moisture content of 58.435-67.149%. The length of smoking increases the protein level. Salted duck eggs with a smoking time of 15 hours have the highest protein content, which is 15.39%. however, the duration of smoking and storage did not affect the total microbes of smoked salted eggs and there was no interaction between the duration of smoking and the duration of storage on the physical, chemical and total microbial properties.

Indonesia is the world’s second largest contributor of plastic waste entering the oceans, where it degrades into microplastics smaller than 1 micron. The use of bioplastics is therefore essential to mitigate environmental pollution. One promising alternative is starch–cellulose blend bioplastic derived from empty fruit bunches (EFB) of oil palm. Indonesia produces about 56.35 million tons of EFB annually, containing approximately 40% cellulose, which makes it a potential raw material for bioplastic production, although commercialization has not yet been realized. Environmentally, converting EFB into bioplastics within the palm oil value chain represents a sustainable waste recycling strategy that transforms solid residues into higher-value products. In this design, soda cooking technology is employed to extract cellulose from EFB, utilizing about 16% of waste from a crude palm oil (CPO) mill with a capacity of 30 tons of fresh fruit bunches (FFB) per hour. The starch–cellulose blend bioplastic pellets are formulated using gelatinized cassava starch as the polymer matrix, glycerol as a plasticizer, polyvinyl alcohol (PVA) as a stabilizer, and cellulose as a filler. The designed production capacity of the EFB-based starch–cellulose bioplastic plant is 16,500 tons per year. This bioplastic industry is expected to contribute positively to achieving eight Sustainable Development Goals (SDGs), including Goals 1, 8, 9, 12, 13, 14, 15, and 17, thereby supporting Indonesia’s commitment to sustainable industrial development and a cleaner environment.
