Regional economic development requires a comprehensive understanding of the structure, potential, and dynamics of economic sectors so that formulated policies can be targeted and sustainable. Bojonegoro Regency as one of the regions in East Java Province has unique economic characteristics with the dominance of certain sectors, so it is necessary to conduct an in-depth analysis of the economic sectors that play a role in driving regional growth. This study aims to identify basic and non-basic sectors, analyze the dynamics of changes in economic sectors, and assess the sectoral competitiveness of Bojonegoro Regency compared to East Java Province. This study uses a quantitative approach with secondary data in the form of Gross Regional Domestic Product at constant prices by business field obtained from the Central Statistics Agency. The analytical methods used include Location Quotient, Dynamic Location Quotient, and Shift Share. The results show that the mining and quarrying sector remains the sector with the most dominant relative advantage in the economic structure of Bojonegoro Regency. However, the analysis of dynamics and competitiveness indicates that several non-extractive sectors are starting to show faster development and growth potential. This finding suggests an opportunity for transformation of the regional economic structure towards a more diverse pattern. The implications of this research emphasize the importance of regional economic development strategies that do not only rely on traditional leading sectors, but also encourage the development of more sustainable potential sectors.

The Indonesian Civil Servants Cooperative (KPRI) plays an important role in enhancing member welfare and supporting the national economy. Nevertheless, increases in business volume and own capital do not necessarily translate into higher profitability, while the number of members an essential characteristic of cooperatives is also assumed to influence financial performance. This study aims to examine the effect of business volume and own capital on cooperative profitability, with the number of members acting as a mediating variable. A quantitative approach was employed using secondary data derived from the financial statements of KPRI in Bogor City during the 2020–2024 period. Purposive sampling was applied, resulting in 12 cooperatives with a total of 60 observations. Panel data regression analysis was conducted using EViews software, and mediation effects were tested using the Sobel test. The results indicate that business volume has a positive and significant effect on cooperative profitability, whereas own capital does not show a significant influence. The number of members has a negative and significant effect on profitability. Furthermore, the Sobel test confirms that the number of members does not mediate the relationship between business volume or own capital and cooperative profitability. These findings suggest that enhancing business activities and improving the quality of member participation are more critical for increasing cooperative profitability than merely expanding capital or membership size.

Viral hepatitis is a systemic disease that primarily affects the liver and is characterized by a necroinflammatory process that plays a significant role in clinical and laboratory manifestations. Chronic hepatitis is defined as liver inflammation lasting more than six months, with persistent elevations in aminotransferases and characteristic histological features, and carries a risk of progression to cirrhosis and hepatocellular carcinoma. Chronic hepatitis C virus infection occurs due to an ineffective host immune response to the virus, allowing the infection to persist. The innate immune system, particularly type I interferon, plays a key role in the initial defense mechanisms against viral replication. Various antiviral therapies, such as interferon, nucleoside analogs, and nucleotide analogs, are currently available, which have been shown to reduce viral load and inhibit disease progression. Appropriate therapy is expected to prevent long-term complications in patients with chronic hepatitis.

The study aims to measure how human emotional states are affected by music, both in increasing happiness and helping individuals manage sadness, musical characteristics such as tempo, tonality, and lyrics play an important role in shaping listeners' affective responses, where upbeat music with fast tempo and major tonality tends to promote positive moods, while melancholy music with slow tempo and minor tonality is more likely to evoke mood reflective or sad. This study used a pseudo-experimental method with a pre-test and post-test design on a group of psychology students of the National University of PASIM, with two songs as a stimulus: "I Love U Bibeh" by The Changcuters and "Jiwa Yang Bersad" by Ghea Indrawati. The measurement instrument was a simple question about the mood of the respondents with a choice of sad or happy. The results showed that the song I Love U Bibeh increased the number of students who reported feeling happy from 30% to 76.7%, while the song Jiwa yang Bersad increased the number of students who reported feelings of sadness from 40% to 63.3%, although some respondents reported catharsis in the form of emotional relief. The discussion emphasized that music has a dual function, namely as a stimulus that is able to change mood as well as a means of regulating emotions through catharsis, with effectiveness that is also influenced by cultural closeness and individual music preferences. The conclusion of this study is that music can be seen as a relevant scientific instrument in supporting students' mental health, strengthening cultural identity, and improving the quality of life, so that the choice of music can be adjusted to emotional needs, both to increase happiness and to help accept and manage sadness.

This research is motivated by the high rate of inability to read the Quran in Indonesia and the urgency of providing appropriate learning stimuli during the golden period of child development. The Al-Husna method was chosen because it emphasizes the principles of simplicity, ease, and tartil, which are considered relevant to the characteristics of early childhood. This study aims to assess the effectiveness of the application of the Al-Husna method in Quran learning at PAUD Tahfidzul Qur'an Yurefi Kendari using the Goal-Oriented Evaluation Model. The research method used is descriptive qualitative, with data collection techniques including observation, interviews, and documentation studies. The evaluation results show that the application of the Al-Husna method has met the learning objectives that have been set at PAUD Tahfidzul Qur'an Yurefi. These achievements include improving students' abilities in recognizing and pronouncing hijaiyah letters with the support of visual codes, mastery of syllables of hijaiyah letters, and understanding the punctuation system using standards according to Rasm Uthmani, achieving efficiency in the use of time and materials in the learning process, and creating a fun, active, and participatory learning environment for children. The identified challenges primarily relate to the need for educators to have a comprehensive understanding of the Al-Husna method. However, schools can address these challenges by implementing ongoing training and mentoring programs. Overall, the findings of this study indicate that the Al-Husna method is effective in building a foundation of basic Quranic reading skills and understanding in early childhood, using a child-friendly and meaningful approach. Therefore, this method can be used as a strategic alternative for teaching Quranic reading and understanding in educational institutions.

This study investigates the determinants of dividend payout policy in energy sector firms listed on the Indonesia Stock Exchange during the 2020–2024 period. Dividend policy is a critical issue in emerging markets, especially in capital-intensive industries with high investment needs and earnings volatility. The research examines whether profitability and ownership structure—specifically institutional and managerial ownership—significantly influence dividend payout decisions, considering firm characteristics. The study analyzes the effect of profitability, institutional ownership, and managerial ownership on the dividend payout ratio, while controlling for firm size and leverage. A quantitative approach is used, employing pooled ordinary least squares (OLS) regression on 245 firm-year observations. Dividend payout ratio is measured as dividend per share divided by earnings per share, profitability is proxied by return on equity, and ownership variables are expressed as shareholding proportions. Descriptive analysis and classical assumption tests precede hypothesis testing. The results show that profitability positively and significantly affects dividend payout, suggesting that firms with better financial performance tend to distribute higher dividends. Firm size also positively influences dividend policy, while leverage negatively impacts it, reflecting the role of financial capacity and capital structure. However, institutional and managerial ownership do not show significant effects on dividend payout decisions. The findings indicate that dividend policy in Indonesian energy firms is primarily driven by financial performance and structural characteristics rather than ownership-based governance mechanisms. This study offers sector-specific evidence that refines agency and signaling perspectives on dividend policy in emerging markets, with practical implications for managers, investors, and regulators.

The development of technology-based peer-to-peer financing services (LPBBTI) in Indonesia, including platforms like Shopee Paylater, has facilitated easier access to credit. However, this progress is accompanied by cybersecurity risks, such as unauthorized use and account breaches. This study aimed to (1) analyze the operation of LPBBTI under prevailing regulations, and (2) examine the legal liability of parties in cases of Shopee Paylater credit breaches.The study employed a normative legal approach with prescriptive characteristics, combining statutory, conceptual, and case-based analyses. Primary and secondary legal materials were obtained through literature review of Law No. 8 of 1999, POJK No. 10 of 2022, POJK No. 40 of 2024, and personal data protection regulations. The analysis was conducted descriptively and qualitatively. The findings indicate that, despite OJK regulations, Shopee Paylater’s electronic agreements still contain standard clauses that unilaterally shift all account security risks to users. This practice potentially violates Article 18(1)(a) of the Consumer Protection Law and is void under Article 18(3). Consequently, consumers remain liable for payments even if transactions are conducted illegally by third parties. In line with Article 19 of the Consumer Protection Law, service providers should assume liability, as system security is under their control.

Adolescent mental health is an important aspect in human resource development because it affects learning ability, social relationships, and readiness to face adult life. Adolescence, especially at the junior high school level, is a transitional period that is prone to mental and emotional disorders due to biological, psychological, and social changes that occur simultaneously. This study aims to describe the mental health condition of adolescents using the Self Reporting Questionnaire (SRQ-20) instrument in students of SMPN 3 Ubud, Gianyar Regency. The study used a descriptive design with a cross sectional approach. The sampling technique was carried out in total sampling with a total of 117 students. The research instrument is in the form of an SRQ-20 questionnaire that has been proven to be valid and reliable. Data analysis was carried out descriptively to describe the distribution of symptoms and mental health categories of respondents. The results showed that most students were in the category of good mental health, although there were still a number of students with poor conditions. The most common symptoms are easy to feel tired and difficulty in making decisions. Based on the characteristics of respondents, students aged 13–15 years are more likely to experience poor mental health conditions than 11-13 years old, and the proportion of female students is higher than men in experiencing symptoms of mental emotional disorders. These findings affirm the importance of early detection of adolescent mental health in schools as the basis for promotive and preventive interventions, through optimizing the role of counseling guidance and creating a supportive school environment.

Working memory (WM) has been extensively studied as a cognitive factor influencing second language acquisition (SLA), but many studies treat it as a static, trait-like capacity. This approach provides limited insight into how WM works across different stages of development, proficiency levels, and learning contexts. This article combines theoretical and empirical research on working memory in SLA from a dynamic and developmental perspective, analyzing how the influence of WM varies over time and interacts with other cognitive and contextual factors. Referencing Baddeley's multicomponent model, complex dynamic systems theory, and longitudinal research, this article examines evidence regarding the role of WM in various language domains, including vocabulary learning, grammar processing, and language production. It also investigates how WM works differently at various proficiency levels and developmental periods, from childhood to adulthood. Evidence suggests that WM plays a very strong role in the early stages of learning when processing is effortful and controlled, but becomes less central as linguistic knowledge becomes automated. The relationship between WM and SLA appears to be bidirectional, with sustained language learning contributing to the development of specific WM components, particularly executive control. The influence of WM varies significantly based on task characteristics, teaching context, and learner profiles. Understanding WM as a dynamic resource rather than a fixed constraint has important pedagogical implications. Instructions that manage cognitive load, provide support, and encourage metacognitive awareness can help learners with diverse cognitive profiles. A developmental approach in WM research requires longitudinal designs and task-aligned methodologies to capture changes over time, thereby advancing theory and practice in SLA.

The construction sector is an industry with a high level of work accident risk due to its dynamic and complex work characteristics. This study aims to examine the application of the Occupational Health and Safety (OHS) System and evaluate its effectiveness in mitigating risks at the Health Facility Building Construction Project (Project X) in Fakfak Regency. The research method used is a descriptive-analytical quantitative approach with purposive sampling of 25 respondents, including executors, supervisors, and field workers. Risk analysis was conducted using the Failure Modes and Effects Analysis (FMEA) method by measuring Severity, Occurrence, and Detection parameters to produce a Risk Priority Number (RPN). The results show that RPN values range from 52.35 to 452.30. The highest risk was found in the variable of limited safety signage in hazardous locations (RPN 452.30), which falls into the very high category. Additionally, 10 high-risk variables and 9 medium-risk variables were identified, dominated by technical, operational, and management factors, such as the use of heavy equipment by uncertified operators and weak implementation of Standard Operating Procedures (SOP) and OHS audits. This study concludes that the application of OHS in Project X is still reactive and requires strengthening risk-based safety management systems as well as improving workforce competence to achieve zero accident conditions.

This aims to examine and analyze the implementation of the cash transfer assistance policy in efforts to alleviate poverty in Moodu Urban Village, Kota Timur Subdistrict, Gorontalo City. This research employed a qualitative method. The findings indicate that the effectiveness of the policy implementation has not yet been optimal due to several influencing factors: (1) policy standards and target groups have not been fully accurate; (2) available resources, both in terms of the number of implementing personnel and supporting infrastructure, remain very limited; (3) inter-organizational communication and activity reinforcement are less effective; (4) the characteristics of implementing agents reveal that some officers do not yet fully understand the procedures and mechanisms for distributing cash transfer assistance; (5) the economic, social, and political environment of the Moodu community, which is predominantly engaged in the informal sector, presents additional challenges in ensuring program effectiveness; and (6) the attitudes of implementers, in the absence of continuous guidance and periodic supervision, increase the potential for administrative errors and inaccurate distribution.

The construction and infrastructure sectors are shifting toward lighter, low-emission, and sustainable materials in response to the high carbon footprint and excessive weight of common materials such as concrete and steel. One promising alternative widely developed is natural fiber–based composites. However, studies comparing mechanical properties of variations of natural fibers within a single framework remain limited. This study aims to evaluate and compare composite mechanical properties reinforced by sisal fiber, bamboo fiber, and pineapple leaf fiber to determine the optimal fiber type for sustainable infrastructure applications. The research methodology involved fabrication of composite specimens using a unidirectional fiber configuration with a resin matrix, molded following ASTM D638 Type I dimensional and geometrical requirements. Tensile testing was conducted to evaluate mechanical responses, including ultimate tensile behavior, deformation characteristics, and elastic properties, which were presented in tabular and graphical forms. The results show that incorporation of all natural fiber types significantly enhanced composite mechanical properties, exhibiting an average tensile strength of approximately 26 MPa. Pineapple leaf fiber demonstrated balanced mechanical behavior combining strength and ductility, while sisal fiber showed superior tensile resistance and rigidity. Bamboo fiber provided moderate mechanical improvement. Overall, natural fiber–reinforced composites demonstrate strong potential as environmentally friendly alternative materials for infrastructure applications, with mechanical characteristics adjustable based on reinforcing fiber type.

The results showed that most respondents had unhealthy dietary patterns and experienced high stress levels. Dietary pattern was significantly associated with stress level (p = 0.038), whereas demographic characteristics were not significantly related to stress level. Patients with unhealthy dietary patterns were more likely to experience high stress. In conclusion, dietary pattern is significantly associated with stress levels among gastritis patients. These findings highlight the importance of promoting healthy eating behaviors as part of stress management strategies in primary health care settings.

Bullying is a form of aggressive behavior commonly experienced by adolescents and has significant impacts on both physical and mental health. Schools, as primary social environments for teenagers, often become settings where bullying occurs. Several factors contribute to this behavior, particularly peer influence, family roles, and social media use. This study aimed to analyze factors related to bullying behavior among adolescents in a junior high school, including respondent characteristics, peer influence, family roles, and social media usage, as well as their relationships with bullying behavior. This research used a quantitative approach with a cross-sectional design involving 71 eighth-grade students as respondents. Data were collected using structured questionnaires and analyzed with the Chi-Square test. The results showed significant relationships between peer factors (p=0.003), family roles (p<0.001), and social media use (p=0.001) with bullying behavior. A large proportion of respondents reported high social media usage (45.1%) and low family involvement (45.1%), while more than half (53.5%) were categorized as being at risk of engaging in bullying behavior. These findings indicate that adolescents are strongly influenced by their social environment, both offline and online. Negative peer interactions and limited family supervision can increase the likelihood of bullying behavior. In conclusion, peer factors, family roles, and social media use are significantly associated with bullying among adolescents. Therefore, collaboration between families, schools, and communities is essential through psychosocial assessments, increased family involvement, and character education programs to prevent and reduce bullying behavior.

The agricultural sector is a vital pillar in maintaining food security and enhancing the livelihoods of rural communities. In an effort to improve agricultural productivity, the Government of Lamongan Regency, through the Food Security and Agriculture Agency (DKPP), has implemented the Agricultural Facilities and Infrastructure Provision and Development Program. This program is designed to strengthen agricultural production capacity by supporting the availability of farming machinery, improving irrigation networks, and developing farm access roads.
