The high volume of fishery waste often poses an environmental burden if not managed appropriately. Conversely, the circular economy concept offers sustainable solutions aligned with Maqasid Shariah principles in environmental preservation (Hifz al-Alam). This study aims to educate and implement the processing of fish waste into high-quality animal feed that meets halal standards (halalan thayyiban). This research employs a qualitative approach using the Asset-Based Community Development (ABCD) method. The stages include socializing the concept of Sharia circular economy, technical training on waste processing, and nutritional content testing of the feed. The findings indicate an 80% increase in community understanding regarding the economic value of waste. Technically, the fish waste processing successfully produced an alternative animal feed with high protein content, free from najis (impurity) through a purification process according to Islamic jurisprudence (fiqh). This education proves that the integration of circular economy and Sharia principles not only reduces environmental impact but also creates sustainable economic added value for local communities.

This study examines the effects of word of mouth, peer influence, and promotion on exercise decisions at gymnasiums in Bandar Lampung City, with hedonic motivation as a mediating variable. Drawing on the Theory of Planned Behavior and consumer behavior perspectives, the research employed a quantitative causal-associative design. Data were collected through structured questionnaires from 100 active members of four gymnasiums and analyzed using Partial Least Squares - Structural Equation Modeling (PLS-SEM) with SmartPLS . The results indicate that word of mouth, peer influence, and promotion have positive and significant effects on hedonic motivation and on exercise decisions. Hedonic motivation also exerts a positive and significant effect on exercise decisions, suggesting that pleasurable and emotionally rewarding fitness experiences reinforce consumers' intention to engage in regular gym- based exercise. Mediation analysis further reveals that hedonic motivation significantly channels the effects of peer influence and promotion on exercise decisions, while the indirect effect of word of mouth is also significant, although its negative coefficient warrants careful interpretation. These findings demonstrate that exercise decisions are shaped not only by utilitarian health considerations but also by social influence, promotional exposure, and affective consumption experiences. The study provides practical insights for gym managers in designing service and marketing strategies that strengthen customer engagement and sustained participation.

This study aims to analyze the marketing strategies of maternal and child healthcare services in hospitals to enhance patient experience, emphasizing a shift from traditional promotional approaches toward the creation of a positive and empathetic patient experience. This research employs a systematic literature review of relevant studies published between 2021 and 2025, with analysis conducted through identification, selection, and thematic synthesis to determine key factors influencing patient satisfaction and loyalty. The findings indicate that the quality of interpersonal interactions and the efficiency of service processes are the primary determinants of patient experience, where factors such as staff empathy, clear communication, reduced waiting times, and well-structured service flows have a greater impact than the technical aspects of medical care. Hospitals should therefore prioritize people- and process-oriented strategies by implementing empathy training, enhancing communication effectiveness, and regularly measuring patient satisfaction, while also integrating digital services, ensuring cost transparency, and developing continuity of care programs to strengthen the patient experience holistically. This study proposes a holistic marketing framework that integrates empathy, efficiency, data-driven personalization, and environmental sustainability, highlighting a shift from a purely clinical orientation to an experiential marketing approach that places human values at the core of a hospital’s competitive advantage.

Adolescent reproductive health is an important aspect that requires special attention, especially regarding the problem of dysmenorrhea or menstrual pain. Dysmenorrhea is often considered normal, even though it can reduce the quality of life and disrupt the learning activities of young women. One factor that influences dysmenorrhea is nutritional status and diet. This community service activity aims to increase the knowledge of young women about preventing dysmenorrhea through health promotion using posters with an anti-inflammatory diet approach based on "Healing Through Nutrition". The activity was carried out at the UPT SMA 9 Bulukumba on May 6, 2025, targeting 20 young women. The activity method included the planning, preparation, implementation, and evaluation stages, with a pre-test and post-test to assess the level of knowledge of participants. The results showed a significant increase in adolescent knowledge about preventing dysmenorrhea. Before the activity, 50% of respondents had poor knowledge, 40% had sufficient knowledge, and only 10% had good knowledge. After the intervention, 80% of respondents had good knowledge and 20% had sufficient knowledge, with no category of poor. These results indicate that poster media is effective in increasing adolescents' knowledge about dysmenorrhea and the importance of an anti-inflammatory diet as a non-pharmacological effort to prevent it.

Modern retail expansion in Situbondo Regency has intensified competitive interaction with traditional markets, making it important to map differences in market structure, firm conduct, and performance outcomes. This study compares (i) market structure using concentration indicators (CR4 and the Herfindahl–Hirschman Index/HHI), (ii) competitive conduct (pricing practices, promotional intensity, service attributes, and relationship patterns), and (iii) performance proxies (sales turnover and selected price efficiency measures) within the SCP framework. The analysis applies a descriptive quantitative approach supported by targeted primary observations and questionnaire-based information, and complemented by official statistics and regulatory documents. Traditional-market samples include Panji, Besuki, and Panarukan markets, while modern-retail samples include local outlets of Indomaret, Alfamart, and Basmalah. Results indicate that traditional markets are relatively unconcentrated (CR4 = 38.0%; HHI = 744), consistent with a competitive structure dominated by many small vendors. Modern retail is more concentrated (CR4 = 77.0%; HHI = 1,644), suggesting moderate concentration and a tendency toward local oligopoly. Average monthly turnover per unit is higher for modern retail (IDR 36.36 million) than for traditional vendors (IDR 15.63 million). Price efficiency varies across commodities: some items show near parity, while several fresh commodities remain cheaper in traditional markets. Policy implications point to balanced local governance: zoning and permitting for modern stores, continuous revitalization of traditional markets, and strengthened MSME partnership schemes to ensure healthy and inclusive competition.

This community service program aims to improve the quality of services at Puskesmas (community health centers) through intensive assistance in content creation and digital communication media. The main issue addressed is the low digital literacy among healthcare workers at Puskesmas in managing effective communication media to reach the public. This has led to low community participation in health programs run by Puskesmas. Therefore, this program is designed to enhance healthcare workers' skills in utilizing digital technology for health promotion and improving communication effectiveness with the public. The program implementation involves several stages: (1) an initial survey to assess the condition of existing communication media, (2) training on creating engaging and informative health education content, (3) workshops on graphic design and health promotion video creation, (4) guidance on using social media platforms to disseminate health information, and (5) continuous evaluation and monitoring to ensure the sustainability of the program. This activity involves 25 healthcare workers from 5 selected Puskesmas, with a mentoring duration of 6 months. The results show significant improvements, including: an increase in healthcare workers' ability to create digital content from 30% to 85%, a 200% increase in public engagement with health information, and a 150% increase in the coverage of health promotion services. Additionally, the program has produced 120 pieces of health education content, 15 health promotion videos, and 8 successful digital campaigns that have successfully enhanced public participation in health programs. The long-term impact of this program is the increased public awareness of preventive health and improved access to Puskesmas services. This program can also be replicated in other regions as a model for improving the quality of primary healthcare services through optimal use of digital technology, which can accelerate the achievement of national health development goals.
