The rapid growth of TikTok Shop as a social commerce platform has led to the emergence of 'toxic content' produced by influencers as a marketing tactic that effectively influences Generation Z's shopping behavior. This study investigates the role of TikTok Shop influencers and their 'toxic content' in stimulating impulse buying behavior among Generation Z consumers in the fast fashion sector, focusing on the psychological mechanisms involved, the most frequently purchased product categories, and the broader impacts of these consumption patterns. A qualitative research approach with a phenomenological design was used, and data were gathered through in-depth interviews with eight informants: six Generation Z consumers aged 19–24 years and two active TikTok Shop fashion influencers, selected via purposive sampling. The data were analyzed using the interactive model of Miles, Huberman, and Saldaña (2014). Findings show that 'toxic content' acts as a stimulus within the Stimulus-Organism-Response (S-O-R) theoretical framework, triggering impulse buying within minutes by evoking positive emotions and urgency. The Fear of Missing Out (FOMO) mechanism, driven by emotional triggers like time scarcity, social proof, and exclusivity, was the most dominant psychological factor. The most commonly purchased items were tops, coordinated sets, aesthetic bottoms, locally-made footwear, and accessories. The effects of 'toxic content' are financial, psychological, social, and environmental. This study advances influencer marketing literature and provides insights into Generation Z’s consumer behavior in the social commerce age.

This study aims to analyze the cultural meaning of social drinking displayed in South Korean films on Netflix in 2024 through the perspective of Charles Sanders Peirce's semiotic theory. Social drinking, as a cultural phenomenon, is not only a social habit in South Korea but is also often used as a narrative element in films to convey cultural values, social dynamics, and interpersonal relationships. Qualitative research methods with a semiotic analysis approach are used to explore the meaning displayed on the representamen, object, and interpretant sides of social drinking in the films Badland Hunters, Officer Black Belt, Mission: Cross, Wonderland, and My Name is Loh Kiwan. The results of the study show that social drinking represents the culture of togetherness of South Korean society that is woven into various contexts, such as work relationships, family, and friendships. In terms of representamen, visual signs in the form of symbols of drinking culture such as soju, banquet tables, and the movement of pouring drinks to each other create a strong picture of togetherness. From the object side, social drinking becomes a medium to highlight solidarity and release social pressure, especially in a hierarchical and competitive work culture. The resulting interpretation shows a dualism of meaning: on the one hand, it strengthens harmony and the value of togetherness, while on the other hand it displays the dark side of this culture, such as excess consumption and its influence on social pressure. This study provides new insights into the role of South Korean films as a medium for conveying global cultural messages, which are able to influence local cultural interpretations outside their country of origin. In addition, this study is expected to enrich the literature on semiotics in visual communication studies with a focus on drinking culture as an element of representation.

This study aims to analyze the dynamics of peer pressure as a factor that forms problematic behavior in adolescents. This study uses a literature review method with more than 19 relevant journals. The selected journals followed inclusion criteria that focused on adolescents, peer pressure, and problematic behaviors within a specific time frame. The results of the study showed that peer pressure contributes to problematic behaviors such as aggressive behavior and social violence (bullying, cyberbullying, aggressiveness, disruptive behavior), addictive and health-risking behaviors (smoking, alcohol consumption/drinking behavior), violations of academic/school norms (truancy, juvenile delinquency), online/sexual risky behavior (cybersex), and internal psychological problems (decreased self-confidence). The psychosocial dynamics found included the need for acceptance, group conformity, low self-control, and weak family support. These influences can be direct or indirect through the internalization of group values. These findings confirm that problematic behaviors are not formed singularly, but from complex interactions between individual factors and the social environment. Therefore, prevention efforts require a collaborative approach between families, schools, and the community.

The results of the 2022 PISA indicate that science skills and interest in Indonesia are still low. One way to increase interest in science is by introducing inventor figure of science and techonology. However, alternative learning media that are communicative and relevant to adolescents' media consumption habits are needed. Therefore, this study aims to design a character design for an inventor in the field of science and technology for a Webtoon comic as an educational tool for adolescents aged 15–18. This study used qualitative and quantitative methods. The qualitative method was used to understand the needs and interests of the target audience and to gather information from the literature for scientific sources in designing the inventor character. The quantitative method was used as one of the character design evaluation criteria, based on voting results by adolescents aged 15–18. The character design used Marika Nieminen's principles: demographics, silhouette and shape, color, and characteristics. Several alternatives were used to generate character designs, which were then evaluated to determine the final design. The character design evaluation will be assessed using several variables within an evaluation framework.

Ramadan brings significant changes in the shopping and consumption patterns of Indonesians. There is an increase in demand for various types of food and beverages, both for sahur and iftar. The purpose of this study is to map the characteristics of food and beverage purchasing and consumption patterns in a seasonal context (Ramadan): strategic implications for UMKM in the Greater Jakarta area. The research design used is descriptive quantitative with data collection techniques implemented by distributing questionnaires. Then, the questionnaire answers are summarized to obtain the frequency distribution of each item in the questionnaire. The population of this study is people domiciled in the Greater Jakarta area. The sample size was determined using the Lameshow formula, resulting in a sample of 100 respondents spread across the Greater Jakarta area. The majority of respondents, namely 92%, stated that they experienced changes in their shopping patterns during Ramadan. The type of food purchased changed (34%) was the most dominant change. The most dominant consumption purchasing decision during Ramadan was the practicality in preparing food (40%), with favorite shopping places being traditional markets (24%) and street vendors (24%). In a consumption analysis, 83% of respondents experienced changes in their consumption patterns during Ramadan, with the most dominant change being in the amount of food consumed (29%). During sahur (pre-dawn meal), respondents tended to consume vegetables (36%) and chicken (22%). Meanwhile, fried foods (38%) and rice cakes (rice cakes) were the favorite dishes for breaking the fast.

Waste-related issues have become increasingly complex environmental challenges as a result of population growth and shifting consumption patterns within society. Although Indonesia has established a legal framework through Law Number 18 of 2008 on Waste Management, its implementation at the community level continues to encounter various obstacles, particularly low legal awareness and an underdeveloped legal culture. This community service program aims to foster and strengthen a legal culture in waste management as an effort to promote environmental sustainability in Mrutuk Village, Widang District, Tuban Regency. The activities were conducted using participatory and descriptive approaches, including legal education, dissemination of waste management regulations, reinforcement of legal substance and enforcement structures, and community-based assistance. The results demonstrate an improvement in public understanding and awareness of the importance of managing waste in accordance with legal provisions, a shift in attitudes from compliance motivated by supervision toward voluntary compliance, and the emergence of community initiatives to actively engage in environmentally oriented waste management. Therefore, strengthening legal culture has proven to be a crucial instrument in encouraging environmentally responsible behavior and supporting the achievement of sustainable development.

Electricity dependence is increasing as people have easier access to electronic devices. However, this ease of access is not always accompanied by adequate energy literacy. In its Community Service program, Universitas 17 Agustus 1945 Jakarta helped to educate the residents in RW06 Kalibaru, Jakarta, about the safe and efficient use of electricity. This community service program was conducted through participatory seminar with a qualitative approach for residents. The activity used informal visual presentations and discussions in an informal atmosphere. The outreach program demonstrated residents' high enthusiasm for the efficiency of electrical equipment usage such as air conditioners, refrigerators, and water pumps. Through the discussion session, residents realized that using air conditioners with too low a power consumption actually leads to higher energy consumption because the compressor runs continuously. Participants understood that investing in automation concepts, such as using water reservoirs, provides significant long-term electricity cost savings. This outreach successfully shifted residents' paradigm from just simply seeking low prices to selecting devices with optimal capacity according to their needs. This education program demonstrates the effectiveness of energy literacy in improving electricity consumption habits at the household level. Therefore, simple technical understanding can boost family economic financial advantages through sustainable effective energy consumptions.

Data collection integrated primary sources from structured questionnaires with secondary data from comprehensive literature reviews. The results demonstrate that Impulsive Buying Behavior and Financial Technology Trust significantly and positively affect Shopee PayLater usage interest. Conversely, Social Media and Financial Literacy do not show a significant positive impact to Shopee PayLater usage interest. These findings provide critical insights into the digital consumption patterns and financial decision-making behaviors of the modern Indonesian youth demographic.

The incidence of hypertension at the Tadoy Community Health Center reached 29.4%, with 78 cases reported among pregnant women in 2023, half of which were pregnancy-induced hypertension (HDK). Hypertension during pregnancy poses short-term risks to both mother and fetus. In addition to pharmacological treatment, non-pharmacological therapies such as warm water foot soaking and Ambon banana consumption are considered beneficial. This study aimed to examine the effects of these two interventions on reducing blood pressure in pregnant women with hypertension. This research employed a qualitative method with a case study approach involving two pregnant women diagnosed with hypertension. The results showed that warm water foot soaking significantly reduced blood pressure from 150/90 mmHg at the first visit to 130/85 mmHg at the second visit, and further to 120/75 mmHg. Similarly, Ambon banana consumption reduced blood pressure from 150/90 mmHg to 140/90 mmHg, and eventually to 120/80 mmHg. Although both interventions were effective, warm water therapy demonstrated greater effectiveness in lowering blood pressure compared to banana consumption. These findings suggest that simple, non-pharmacological interventions can help manage hypertension in pregnancy. It is recommended that pregnant women apply warm water foot soaking independently to help control blood pressure and reduce pregnancy-related risks.

The phenomenon of phubbing and extreme digital content consumption has become a new challenge in public health, especially for Generation Z, who spend up to 10 hours a day on the internet. This study aims to analyze how phubbing behavior and dependency on endurance streaming distort the quality of face-to-face social interaction and its implications for mental health determinants. The research method employed is a literature review with a critical-narrative approach. Data were collected through systematic searching of reputable scientific databases (such as Google Scholar, SINTA, and GARUDA) focusing on publications from 2021 to 2026. The analysis was conducted by synthesizing literature findings integrated with preliminary field observations to validate the phenomenon's relevance in the local context. The results reveal that snubbing others in favor of gadgets is a mechanism to escape the reciprocal emotional burden of real-life communication. Digital spaces are perceived as safer because they offer intimacy without risk, yet they systematically trigger a chronic erosion of social attention and executive dysfunction. From a public health perspective, this condition threatens social capital and community resilience. This study concludes the importance of sociopsychological interventions to restore human connection to prevent chronic emotional isolation in the future.

Drug stockouts in hospitals pose significant risks to service quality, patient safety, and operational efficiency. This study aimed to analyze how drug demand planning and procurement processes at Johar Baru Regional General Hospital contribute to stockout occurrences and to develop data-driven recommendations based on supply chain management principles. A qualitative descriptive design was employed using data triangulation. Data were collected through in-depth interviews with the Head of the Pharmacy Installation, procurement staff, and warehouse pharmacists, complemented by direct observation and analysis of 2024 planning and procurement documents. Thematic analysis was conducted with the support of NVivo software to identify patterns and relationships among key variables, including drug demand planning, procurement, and inventory management.Findings reveal that stockouts stem from interconnected weaknesses in planning accuracy, procurement coordination, and inventory control systems. Effective stock management depends not only on increasing supply but also on improving data quality, integrating inventory information systems with operational workflows, and enhancing cross-functional collaboration. Recommended strategies include implementing a minimum stock alert system integrated with the Hospital Management Information System (HMIS), strengthening standard operating procedures for stockout response and procurement confirmation, improving integration between HMIS, the National Formulary, and budgeting systems, and applying consumption based planning methods combined with ABC VEN analysis to optimize inventory control.

The development of digital culture has significantly changed the communication, relationships, and spirituality of the younger generation, requiring the Church to reconsider its catechetical methods in the context of social media. This article aims to analyze digital catechesis as a space where faith can develop for the younger generation, by examining the theological foundations, the dynamics of digital culture, and the challenges and models for its development. This study adopts a literature review method by conducting a systematic review of Church Magisterial documents, theological works, and academic research related to the religiosity of the younger generation in the digital environment. The research findings indicate that social media can become a place of faith encounter if catechesis focuses not only on the delivery of religious content but also offers a relational experience that is dialogical, participatory, and community-oriented. However, there are serious challenges such as the risk of superficiality, spiritual consumption, the dominance of algorithms, the commodification of religious content, and the issue of doctrinal authority in the digital space. Therefore, the development of digital catechesis must be based on Christocentrism, fidelity to Church teaching, and a combination of online guidance and concrete sacramental life. With an approach that takes context and reflection into account, digital catechesis has the potential to be a significant and transformative tool of evangelization for young people in the evolving culture of social media.

This study aims to redesign the raw material yarn warehouse layout at PT. XYZ using the Class Based Storage method to improve storage and retrieval efficiency. The main problem identified in the warehouse is random item placement, resulting in relatively long retrieval times of approximately 10–15 minutes per pallet. This research applies a descriptive quantitative approach using a case study method. The data used consists of inbound, outbound, and inventory records of yarn raw materials from November 2024 to April 2025. The analysis was conducted using the FSN (Fast Moving, Slow Moving, and Non-Moving) method through the calculation of consumption rate and average stay, combined with ABC classification to determine storage priority. The results show that 9 types of yarn are classified as Class A, 11 types as Class B, and 11 types as Class C. Based on this classification, a new warehouse layout was designed by placing Class A items near the input-output area, Class B items in the middle area, and Class C items in the back area of the warehouse, thereby improving storage efficiency and reducing retrieval time.

The proliferation of cloud infrastructures has intensified concerns regarding data security, integrity, identity and access management, and user privacy. Despite recent advances, existing solutions often lack comprehensive integration of privacy-preserving mechanisms, dynamic trust management, and cross-provider interoperability. This study proposes an AI-enabled, zero-trust, blockchain-fused identity management framework for secure, privacy-preserving multi-cloud environments. The framework integrates homomorphic encryption with differential privacy for aggregate-level protection and secure multi-party computation for collaborative data processing. The proposed system was validated in a simulated multi-cloud environment using CloudSim, Ethereum blockchain, and AWS EC2. Experimental results indicate homomorphic encryption latency of approximately 450ms per operation and statistically significant security improvements (t(128) = 12.47, p < 0.001), privacy (t(95) = 8.93, p < 0.001), and throughput (t(156) = 15.21, p < 0.001). The framework achieved differential privacy with ε = 0.1 while retaining 99.2% data utility, and demonstrated a 34% improvement in processing speed over conventional differential privacy approaches. In addition, the implementation was observed to be 2.3× faster than BGV-based configurations, with 45% lower memory consumption than CKKS and a 67% reduction in ciphertext size relative to baseline implementations. From an operational perspective, the framework shows a 23% reduction in security management costs, a 31% improvement in resource utilization efficiency, and an 18% decrease in compliance audit expenses. The model further indicates a 27% reduction in total cost of ownership (TCO) compared with multi-vendor security solutions, a projected return on investment (ROI) within 14 months, and an 89% reduction in security incident response costs under the evaluated conditions.

Fully Homomorphic Encryption (FHE) enables computation on encrypted data with end-to-end confidentiality; however, its practical adoption remains limited by substantial computational costs, including long encryption and decryption times, high memory consumption, and operational latency. Zero-Knowledge Proofs (ZKPs) complement FHE by enabling correctness verification without revealing sensitive information, although they do not support encrypted computation independently. This study integrates both techniques to enable encrypted computation with verifiably consistent results. A prototype system is implemented in Python using Microsoft SEAL for homomorphic encryption and PySNARK for Zero-Knowledge Proof verification. Experiments are conducted on standard consumer-grade hardware (Intel i5, 8 GB RAM, Ubuntu 22.04) using datasets ranging from 100 MB to 1 GB. The evaluation focuses on encryption and decryption time, homomorphic computation latency, memory usage, and proof generation overhead. Experimental results show that integrating ZKPs introduces a moderate and stable runtime overhead of approximately 15–20%, as analyzed in Section 4, while enabling verification without plaintext disclosure. Ciphertext expansion remains a notable limitation, with observed growth of approximately 30–40× relative to plaintext size, consistent with prior FHE implementations. Despite these overheads, the system demonstrates feasible scalability for datasets up to 1 GB on mid-level hardware. Overall, the results indicate that the integrated FHE+ZKP approach provides a practical balance between confidentiality, verifiability, and performance, supporting its applicability to privacy-preserving scenarios such as secure cloud computation, encrypted data analytics, and confidential data processing under realistic resource constraints.

Food Additives (BTP) in current consumer products increase the risk of non-communicable diseases such as diabetes, kidney failure, and cancer, particularly in children. Housewives play a central role in managing family consumption to minimize these risks. This community service activity aims to enhance the knowledge and awareness of 'Aisyiyah women in Buluspesantren, Kebumen Regency, regarding food safety and BTP regulations. The implementation method included preparing materials based on BPOM regulations, interactive education, product discussions, and simulations on reading nutrition labels. The results showed high enthusiasm from participants who are now more critical in distinguishing between natural and synthetic additives. Participants reported a significant improvement in their ability to identify food ingredients and additives in everyday products. The final evaluation recorded a 22.2-point increase in participant understanding. By establishing the habit of reading food labels, it is expected that the risk of non-communicable diseases within the family environment can be reduced, thus improving public health literacy and dietary choices within the community.

This research investigates intelligent cooling system design for main ship engines operating in tropical waters, integrating advanced machinery engineering with human factors to address thermal management challenges affecting engine performance, reliability, and crew operational effectiveness. Tropical maritime environments impose severe cooling demands through elevated seawater temperatures (28-32°C), high ambient conditions (28-35°C), and accelerated biofouling, reducing conventional cooling system effectiveness by 15-25% while increasing maintenance burdens and operational risks. Through qualitative analysis involving marine engineers, chief engineers with tropical operational experience, cooling system manufacturers, naval architects, automation specialists, and maritime training institutions, this study examines how intelligent cooling systems incorporating variable-speed pumps, adaptive control algorithms, predictive maintenance, and crew-centered interfaces can optimize thermal management while supporting effective human-machine collaboration. Results demonstrate that intelligent systems can reduce cooling energy consumption by 20-35%, improve temperature stability by 50-65%, extend maintenance intervals by 40-80%, and enhance crew situational awareness through intuitive monitoring interfaces, while requiring comprehensive training programs developing technical understanding and operational competencies. Key implementation challenges include control system complexity, sensor reliability in harsh marine environments, integration with existing engine management platforms, crew competency development requirements, and lifecycle cost justification. Findings reveal that successful intelligent cooling system implementation requires holistic sociotechnical approach addressing machinery engineering optimization, automation technology deployment, and human capability development through coordinated design and training strategies. This research contributes to marine engineering literature by providing integrated frameworks for intelligent system design incorporating machinery performance, automation capabilities, and human factors supporting operational excellence in tropical maritime operations.

Based on Law No. 11 of 2006 and Qanun Aceh No. 4 of 2010, the Government of Aceh has special authority in implementing prioritized health services for poor communities as part of its special autonomy. In practice, the Aceh Health Insurance (JKA) program provides health coverage for all Acehnese residents, including underprivileged groups, by covering insurance contributions and several referral and companion costs not fully guaranteed by the national health insurance system. This study aims to analyze the implementation system of JKA, examine the responsibility of the Aceh Government in providing health insurance for its citizens, and evaluate the government’s obligation to pay contributions for poor participants. This research uses an empirical juridical method with a sociological approach and utilizes both primary and secondary data. The results show that several provisions in the Qanun as the legal basis for JKA implementation are not fully aligned with field conditions and the Social Security Administrator Law. In practice, the Aceh Government bears insurance contributions and various referral costs for residents, including poor communities. Although the obligation to pay contributions for the poor has been implemented, funding for referral transportation, companions, and their consumption has not been fully covered, especially for inter-regional advanced healthcare services. Therefore, the Aceh Government needs to revise Article 43 of Qanun Aceh No. 4 of 2010 and evaluate the JKA program to ensure more targeted healthcare financing.        

Hypertension is a significant global health problem, especially in specific groups such as pregnant women. The high incidence and potential for serious complications demand non pharmacological management efforts and innovative use of local foods. This study examines the potential of local functional foods such as Ambon bananas, banana blossoms, and bamboo shoots as alternatives for health management and product development, particularly those related to hypertension in pregnant women. The method used was a systematic literature review using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach, which encompasses four main stages: identification, screening, feasibility assessment, and analysis of results.The study results showed that the Ambon banana diet significantly reduced systolic and diastolic blood pressure. Factors such as age, family support, stress levels, and fast food consumption were shown to be significantly associated with the incidence of hypertension in pregnant women. Furthermore, bamboo shoot consumption significantly reduced blood cholesterol levels and blood pressure. In terms of product innovation, the fish floss formulation combined with banana blossoms or bamboo shoots received positive feedback from the panelists. The fermentation process of bamboo shoots is known to produce flour with a very high crude fiber content. Therefore, this local food has significant potential as a source of additional fiber and a raw material for value-added processed products to support food security and improve public health.
