Street vendors play an essential role in urban informal economies by fulfilling community needs and supporting local economic activity. This study analyzes the role of business ethics in building consumer trust among street vendors in Dumai, Indonesia. A qualitative descriptive method was applied using interviews, observation, and documentation involving three vendors and two consumers. Findings indicate that ethical practices such as honesty in transactions, responsibility for product quality, friendly service, and cleanliness of business premises improve consumer comfort and perceived safety. These conditions encourage repeat purchases, customer loyalty, and a positive reputation for vendors. Therefore, business ethics function not only as moral guidance but also as social capital supporting the sustainability of informal microenterprises. This study highlights that ethical behavior is crucial for strengthening long-term relationships between vendors and consumers in urban settings. Overall, implementing ethical standards contributes to sustainable small business development in informal sectors. It also improves public trust.

The development of social media in the digital era has significantly changed children’s social interaction patterns. Besides providing benefits such as easier access to information and opportunities for creativity, social media also brings negative impacts on children’s psychological, social, and moral development. This study aims to analyze the restriction of social media use among children from the perspective of Jürgen Habermas, especially regarding the concepts of the public sphere, communicative rationality, and the colonization of the lifeworld. This research uses a literature study method with a qualitative descriptive approach through the collection and analysis of relevant scientific articles. Data validity was strengthened through inclusion and exclusion criteria as well as source triangulation. The findings indicate that social media use among children has an ambivalent impact. Positive effects can emerge when there is strong parental supervision, while weak supervision increases the risk of exposure to harmful content, psychological problems, and reduced quality of social interaction. Restricting social media use through time regulation, content control, and digital education is considered important for protecting children’s development. From Habermas’s perspective, children are vulnerable in the digital public sphere because of their limited communicative rationality. Therefore, restrictions are viewed as efforts to protect children’s values and rationality from distortion by the digital media system.

Mergers and acquisitions have served as a primary strategy for global banking consolidation over the past three decades, including in Indonesia, which is currently undergoing one of its most massive consolidation waves—one notable example being the emergence of Bank Syariah Indonesia. This article aims to provide a narrative review of the literature on the operational impacts of mergers on bank performance, with a particular focus on implications for the Indonesian context. Based on a systematic search of the Scopus database, 52 peer-reviewed articles published between 2000 and 2025 were analyzed using a narrative thematic synthesis approach. Five main themes were identified: cost efficiency, service quality, risk management, human resource and cultural integration, and information systems and technology integration. The key findings indicate that although 73.1% of studies report post-merger improvements in cost efficiency, these benefits are highly contingent upon the quality of post-merger integration especially in the areas of human resources, organizational culture, and information technology with IT integration failure rates reaching as high as 75%. Domestic mergers consistently achieve efficiency gains more rapidly than cross-border mergers, whereas risk implications depend heavily on the type of merger and the quality of integration. Policy implications include the need for the Financial Services Authority (Otoritas Jasa Keuangan) to monitor post-merger integration quality, provide integration guidelines for smaller banks, take into account the specific characteristics of Islamic banks, and ensure a streamlined, non-burdensome licensing process. Further research particularly empirical studies on banking mergers in Indonesia—is urgently needed to test the generalizability of global findings to the local context.

Laparotomy is a major surgical procedure associated with a high risk of acute postoperative pain. According to Gan (2017), if pain is not properly managed, it can progress to chronic pain. (Toro et al., 2018) reported that severe pain on the first postoperative day is still commonly found in laparotomy patients, while (Small & Laycock, 2020) indicated that moderate to severe pain within the first 24 hours following major surgery remains a significant clinical issue. This study aims to evaluate the effectiveness of pharmacological pain management following laparotomy under general anesthesia, specifically to identify the types of opioid analgesics used, analyze their effectiveness in reducing pain intensity, identify side effects, and examine administration techniques and routes. This study employed a Systematic Literature Review (SLR) method following the PRISMA guidelines. Literature searches were conducted in the PubMed, ScienceDirect, and SpringerLink databases covering the years 2015–2026. The included studies comprised randomized controlled trials (RCTs), cohort studies, and retrospective studies addressing opioid pharmacological pain management in adult patients following laparotomy under general anesthesia. Study quality assessment was performed using the Joanna Briggs Institute (JBI) instrument. A total of 11 studies met the inclusion criteria. The results of the systematic literature review indicate that opioids are effective in reducing postoperative pain following laparotomy under general anesthesia. The most commonly used opioids are morphine, fentanyl, and oxycodone. Of all the opioids reviewed, oxycodone provided the best pain control, while intrathecal morphine was most effective in reducing the need for supplemental opioids during the early postoperative period. Other opioids, such as extended-release dinalbuphine sebacate and tegileridine, are also effective, but the number of studies is still limited. The most common side effects are nausea, vomiting, pruritus, sedation, and dizziness. Pharmacological pain management using opioids is effective in reducing the intensity of postoperative pain following laparotomy under general anesthesia. Morphine, fentanyl, and oxycodone are the most commonly used opioids. Oxycodone and intrathecal morphine have shown good results in improving pain control and reducing the need for supplemental opioids. The selection of opioid type, dosage, and administration technique must be tailored to the patient’s clinical condition to achieve optimal analgesia with minimal side effects.

Dry eye syndrome (DES) is a common ocular surface disorder that can impair visual function and quality of life, particularly among working-age adults. Although DES has a multifactorial etiology, nutritional factors, such as omega-3 fatty acid intake, have been suggested to modulate inflammation associated with the condition. This study aimed to investigate the association between dietary omega-3 intake and dry eye syndrome in adults. This cross-sectional analytical observational study included 88 participants aged 15-59 years. Participants were selected using consecutive non-random sampling and assessed with a Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ) to estimate omega-3 intake, while dry eye symptoms were evaluated using the Ocular Surface Disease Index (OSDI). Statistical analyses included chi-square and Fisher’s exact test. The results showed that 51.1% of the participants had insufficient omega-3 intake (<250 mg/day), and 29.5% experienced dry eye syndrome. No statistically significant association was found between sex or age and DES occurrence. However, a significant association was found between omega-3 intake and dry eye syndrome (p < 0.001), with individuals consuming insufficient omega-3 having a substantially higher risk of developing DES. These findings suggest that adequate omega-3 intake may play a protective role in dry eye syndrome. This study underscores the potential of dietary interventions as a strategy for preventing and managing DES.

The study underscores the need forfurther empirical research to examine the effectiveness of mindful leadership across diverse educational contexts.

Diarrhea remains a leading cause of mortality among toddlers in Indonesia, with a prevalence reaching 4,9%. In addition to pharmacological management through LINTAS DIARE, non-pharmacological therapies such as baby massage are increasingly being implemented as supportive interventions that families can perform to accelerate recovery. This study aims to examine the effectiveness of baby massage as a complementary therapy in reducing the frequency and intensity of diarrhea in toddlers. The method used involved identifying relevant articles from Google Scholar and Semantic Scholar databases using appropriate keywords. Based on the 6 articles obtained, baby massage significantly (p = 0,000) reduces the frequency and intensity of diarrhea through vagus nerve stimulation, which optimizes intestinal peristalsis and nutrient absorption. Beyond improving defecation patterns, this therapy is proven to significantly increase infant weight, accelerate motor development through central nervous system stimulation, and enhance sleep quality and comfort.

Blasting is a critical method for overburden removal in open-pit coal mines, where fragmentation quality directly impacts loading efficiency and operational costs. This study aims to analyze the actual fragmentation resulting from overburden blasting at Pit 4 Middle of PT. Victor Dua Tiga Mega, Central Kalimantan, to predict fragmentation using the Kuz-Ram model, and to evaluate the conformity of both results against the company standard (boulder size ≤144.6 cm or ≥50 cm for analysis). The research employed a quantitative comparative method. Primary data included blasting geometry and photographs of muck piles from 10 blasting events, which were analyzed using WipFrag software to obtain actual fragmentation distribution. Secondary data comprised rock characteristics and explosive properties for Kuz-Ram prediction input. The results showed significant variation in actual boulder percentage (≥50 cm), ranging from 6.19% to 32.91% with an average of 16.05% (medium category). Statistical analysis revealed a very weak negative correlation (r = -0.21) between powder factor (PF) and boulder percentage, indicating that PF is not the dominant factor within the consistent application range (0.21-0.23 kg/bcm). Comparison with Kuz-Ram predictions showed that the model consistently over-predicted coarse material, with an average difference of +25.21%, suggesting the need for rock factor (A) recalibration. It is concluded that the blasting results are inconsistent, strongly influenced by uncontrollable factors such as geological conditions. Recommendations include geometri evaluation, particularly burden and spacing, and calibration of the Kuz-Ram model for more accurate future predictions.

Thalassemia is a chronic genetic disease that requires long-term treatment and affects children's quality of life physically, psychologically, socially, and academically due to chronic anemia and regular blood transfusion needs. This study aimed to determine factors influencing the quality of life of children with thalassemia at Rumah Sakit Anak dan Bunda Harapan Kita. A descriptive design with a cross sectional approach was used, involving 41 respondents through total sampling. Data were collected using the Pediatric Quality of Life Inventory (PedsQL 4.0 Generic Core Scale) and respondent characteristics including age, gender, socioeconomic status, parental education, and frequency of blood transfusions. Data were analyzed using univariate and bivariate analysis with the Chi-Square test. The results showed most respondents were under ten years old, female, from families with socioeconomic status below the minimum wage, had parents with high school or higher education, and received blood transfusions every three weeks. Bivariate analysis indicated only the frequency of blood transfusions was significantly associated with quality of life, while other variables were not. Thus, transfusion frequency is the main factor influencing quality of life in children with thalassemia.

The development of artificial intelligence (AI) has transformed organizational landscapes and driven fundamental changes in leadership practices and strategic management. This article aims to critically examine AI-based leadership by highlighting its opportunities, risks, and implications for strategic management. The study employs a qualitative literature-based approach using an integrative literature review strategy. The data consist of secondary scholarly literature relevant to AI, leadership, governance, innovation, and strategic management, which were analyzed through qualitative thematic analysis and conceptual content analysis. The findings show that AI-based leadership creates opportunities in the form of improved decision quality, faster strategic analysis, operational efficiency, stronger innovation, and enhanced organizational agility. However, AI integration also presents risks, including algorithmic bias, limited decision transparency, technological dependency, accountability challenges, and ethical concerns. This study confirms that AI does not fully replace human leaders; rather, it fosters a hybrid leadership model that requires technical, adaptive, transformational, and ethical capabilities. The study implies that the effectiveness of AI-based leadership depends on responsible governance, organizational cultural readiness, and balanced human–machine collaboration in supporting strategic management.

Anemia is a common nutritional problem among adolescent girls and can affect health, learning ability, and the quality of future generations. Hemoglobin (Hb) levels can be influenced by dietary intake, such as folic acid and vitamin C, as well as consumption behaviors, including tea drinking habits and adherence to iron supplementation (TTD). This study aimed to examine the relationship between folic acid intake, vitamin C intake, tea drinking habits, and adherence to TTD consumption with hemoglobin levels among adolescent girls in senior high schools in Tuban District. This study used a cross-sectional design with a sample of 325 respondents selected through probability sampling. Data on folic acid and vitamin C intake were obtained using a 24-hour dietary recall method, while tea drinking habits and adherence to TTD consumption were collected through questionnaires. Hemoglobin levels were measured directly using a hemoglobin testing device. Data analysis was performed using the Spearman correlation test. The results showed significant relationships between folic acid intake and hemoglobin levels, vitamin C intake and hemoglobin levels, adherence to iron supplementation and hemoglobin levels, and tea drinking habits and hemoglobin levels, with a negative direction of association. This study concludes that folic acid intake, vitamin C intake, tea drinking habits, and adherence to TTD consumption influence hemoglobin levels in adolescent girls. Efforts to prevent anemia should focus on improving dietary patterns, proper use of iron supplementation, and regulating tea drinking habits.

Irregular sleep patterns are a common issue experienced by university students and are often considered a normal part of academic life. However, such conditions can have negative effects on students’ learning concentration and cognitive function. Poor sleep patterns are generally influenced by various factors, including high academic workload, habitual late-night activities, poor time management, and excessive use of electronic devices at night. This study aims to examine the relationship between sleep patterns and students’ learning concentration, identify factors contributing to irregular sleep patterns, and analyze constraints as well as propose solutions to improve sleep quality in order to enhance learning concentration. The method used in this scientific paper is a literature review, which involves examining relevant scientific sources such as research journals and academic literature related to sleep patterns and students’ learning concentration. The results of the review indicate that students with poor sleep patterns tend to experience physical fatigue, decreased immune function, cognitive impairment, and difficulties in maintaining focus and concentration during the learning process. In the long term, these conditions have the potential to reduce academic achievement and learning motivation. Therefore, it can be concluded that effective time management, limiting the use of electronic devices before bedtime, creating a conducive sleep environment, and support from universities through health education play an important role in improving students’ sleep patterns. With regular and high-quality sleep, students’ learning concentration is expected to improve, allowing the learning process and academic achievement to proceed optimally.

The study of power in higher education institutions is important because power dynamics influence not only formal organizational systems but also informal relationships within academic communities. This research aims to analyze patterns of power manifestation in higher education institutions, understand their influence on organizational behavior, and identify the structural and cultural aspects involved in the process. The method applied in this study is a Systematic Literature Review (SLR), conducted through collecting, reviewing, and synthesizing various relevant literature related to power and governance in higher education. The findings indicate that pro-social manifestations of power and structural empowerment can positively contribute to job satisfaction and create a healthier and more conducive academic climate. On the other hand, centralized authority and unequal power relations may generate various negative impacts on organizations, such as reduced participation and institutional effectiveness. Therefore, higher education institutions need to implement a more participatory and adaptive governance model to minimize the negative effects of power asymmetry while strengthening collaboration, inclusiveness, and the overall quality of the academic environment.
