Tomato (Solanum lycopersicum) is an economically important crop whose productivity is increasingly constrained by drought stress under changing climatic conditions. Conventional breeding for drought tolerance is often slow because this trait is quantitatively inherited and strongly influenced by environmental factors. Molecular markers, particularly Simple Sequence Repeats (SSRs), have become valuable tools for improving selection efficiency and accelerating breeding progress. This review examines the role of SSR markers in the development of drought-tolerant tomato cultivars. The physiological, biochemical, and molecular responses of tomato to drought stress, including growth reduction, photosynthetic impairment, osmotic adjustment, hormonal regulation, and oxidative stress responses, are briefly discussed. The genetic characteristics of SSR markers, including their high polymorphism, co-dominant inheritance, and multi-allelic nature, are highlighted as key advantages for genetic analysis and breeding applications. Furthermore, the review synthesizes recent findings on the use of SSR markers for genetic diversity assessment, Quantitative Trait Loci (QTL) mapping, and identification of genomic regions associated with drought-related traits such as relative water content, chlorophyll stability, root architecture, and proline accumulation. The application of SSRs in Marker-Assisted Selection (MAS), including marker-assisted backcrossing and QTL pyramiding, is also discussed. Finally, the review evaluates the continuing relevance of SSR markers in the genomic era, emphasizing their complementary role alongside Single Nucleotide Polymorphism (SNP) markers, Genome-Wide Association Studies (GWAS), and Genomic Selection (GS). Integrating SSR-based approaches with modern genomic tools offers a promising strategy for developing climate-resilient tomato cultivars and enhancing future food security.

Employee performance is a critical element in organizational success, particularly in labor-intensive industries such as garment manufacturing. This study aims to analyze the effect of work stress (X1) and work environment (X2) on employee performance (Y) in garment industry companies in Semarang Regency. A quantitative descriptive approach with multiple linear regression analysis was employed. The population and sample comprised 96 employees using total sampling. Data were collected through a Likert-scale questionnaire (1–5) with 10 items per variable. All classical assumption tests (normality, multicollinearity, heteroscedasticity) were satisfied. Reliability tests yielded Cronbach's Alpha of 0.866 (work stress), 0.941 (work environment), and 0.937 (employee performance), confirming instrument reliability. Results indicate: (1) work stress has no significant partial effect on employee performance (t = 1.581; sig. = 0.117); (2) work environment has a significant positive partial effect on employee performance (t = 9.618; sig. = 0.000); (3) simultaneously, both variables significantly affect employee performance (F = 56.630; sig. = 0.000) with a coefficient of determination (R²) of 54.9%. These findings confirm that optimizing the work environment both physical and non-physical is the primary strategic priority for enhancing employee performance in the garment industry.

Heat stress is a major constraint in broiler production systems located in humid tropical climates, where high ambient temperature and relative humidity impair growth performance, feed efficiency, and animal welfare. This systematic review synthesizes peer-reviewed studies published between January 2015 and December 2025 evaluating environmental housing designs and cooling strategies for mitigating heat stress in broiler chickens. This systematic review followed the PRISMA 2020 guidelines and synthesized peer-reviewed studies retrieved from Scopus, Web of Science, and ScienceDirect, published between January 2015 and December 2025. From 500 records initially identified, 26 studies fulfilled the predefined eligibility criteria and were included in the qualitative synthesis. The findings demonstrate that evaporative cooling systems, tunnel ventilation, and automated climate control technologies consistently reduced indoor temperature (2–6°C) and improved body weight gain, feed conversion ratio (FCR), and mortality rates under hot-humid conditions. However, cooling efficiency was strongly influenced by ambient humidity, necessitating integrated and adaptive environmental control approaches. Smart sensor-based systems further enhanced microclimate stability and thermal uniformity within broiler houses. Beyond performance improvements, optimized environmental management reduced physiological stress indicators, including heterophil-to-lymphocyte ratios and corticosterone levels. Overall, integrated, humidity-adaptive, and energy-efficient cooling strategies are essential to sustain productivity, welfare, and climate resilience in tropical broiler production systems.

Breastfeeding should ideally begin immediately after birth and be provided exclusively for the first six months of life. However, in 2022, the coverage of exclusive breastfeeding among infants aged 0–6 months in Jayapura was only 21%, which remains far below the national target of 45%. Various factors contribute to this low coverage, including limited knowledge, lack of experience, insufficient support systems, and concerns among adolescent mothers that breastfeeding may interfere with their education or employment. This study aimed to explore the breastfeeding experiences of adolescent mothers in Wahno Village, Abepura Subdistrict. A qualitative research design was used, with structured interviews conducted using a questionnaire. The results indicated that the initiation of exclusive breastfeeding among adolescent mothers was generally positive. Participants reported mixed emotional experiences, including feelings of happiness, pride, stress, and discomfort. Family support, particularly from husbands, played an important role in sustaining breastfeeding practices. Most respondents also demonstrated adequate knowledge regarding how to manage breastfeeding-related challenges. Overall, adolescent mothers in Wahno Village showed a reasonable level of understanding and commitment toward exclusive breastfeeding. Continued education and support are recommended to further strengthen breastfeeding practices among adolescent mothers and their families.

The rapid development of the digital era has significantly impacted adolescents by increasing academic stress due to academic demands, performance pressure, and technological distractions.

Sandwich composites are lightweight structural materials with a high strength-to-weight ratio and have potential as alternatives to conventional materials. This study aims to analyze the effects of core thickness variation and the number of skin layers on the bending strength of fiberglass-skinned sandwich composites with an A-flute cardboard honeycomb core. The research employed an experimental method using three-point bending tests in accordance with ASTM C393. Core thicknesses of 10 mm, 20 mm, and 30 mm were investigated, while the number of fiberglass skin layers was varied at 1, 2, and 4 layers. Bending strength was evaluated based on core shear strength and skin bending stress, expressed in MPa. The results show that the highest average core shear strength was obtained at a core thickness of 10 mm with 4 skin layers, while the lowest value occurred at a core thickness of 30 mm with 1 skin layer. The highest skin bending stress of 43.40 MPa was achieved by the specimen with a 10 mm core thickness and 1 skin layer, whereas the lowest value of 11.83 MPa was observed at a 30 mm core thickness with 4 skin layers. These results indicate that increasing core thickness tends to reduce bending strength based on core shear strength, while increasing the number of skin layers enhances the bending performance of the sandwich composite, and an interaction effect between the two variables is present.

This study aimed to analyze the influence of workload and burnout on nurses’ sleep quality while controlling for age, gender, and education as potential confounding variables. A quantitative analytic study with a cross-sectional design was conducted among 156 nurses working in a private hospital in Depok City. Data were collected using a workload questionnaire, the Maslach Burnout Inventory (MBI), and the Pittsburgh Sleep Quality Index (PSQI). The data were analyzed using Chi-Square tests and multiple logistic regression. The findings showed that both workload and burnout had significant effects on sleep quality (p < 0.05), with burnout identified as the most dominant factor. Age and gender were also significantly associated with sleep quality, whereas education did not show a statistically significant effect. The regression model demonstrated excellent fit, indicated by a McFadden pseudo R² value of 0.908. These results suggest that occupational factors, particularly burnout, play an important role in determining nurses’ sleep quality. Therefore, effective stress reduction and workload management strategies are needed to support nurses’ well-being and improve sleep quality.

Technological advances and increasing job demands have made work stress a major concern in modern industrial environments. Noise is one of the physical workplace factors that may contribute to work stress. This study aimed to analyze the relationship between noise exposure and work stress among workers in the spinning department of PT X. A quantitative cross-sectional design was employed, involving 80 workers selected through purposive sampling. Noise levels were measured using a sound level meter, while work stress data were collected through a standardized questionnaire. Data were analyzed using the Chi-Square test.Most respondents were over 35 years old (80%) and female (54%). The highest noise level was recorded in the spinning room (102.17 dBA), while the fiber preparation room had the lowest level (84.07 dBA). Most workers experienced mild work stress (86.25%), whereas 13.75% reported moderate to high stress. The Chi-Square test showed no statistically significant relationship between noise and work stress (p = 0.074). However, the Likelihood Ratio test indicated a significant positive trend (p = 0.021). These findings suggest that excessive noise exposure may increase work stress and highlight the need for effective noise control, hearing protection, and stress management programs in the workplace.

 Toxic work environments are becoming an issue that is getting more and more attention in human resource management because of its destructive impact on the psychological well-being of employees and organizational stability. Unhealthy interpersonal relationships, authoritarian leadership, bullying, and recurrent disrespectful behavior create a work atmosphere full of stress and uncertainty. This condition not only triggers work stress, anxiety, and emotional exhaustion, it further exacerbates these challenges, as high work demands and a lack of work-life balance make employees, especially Generation Z, increasingly vulnerable to mental health disorders. This study aims to analyze the influence of toxic work environments on employees' mental health as well as its impact on the intention to quit their jobs. The method used is a literature study with a qualitative approach, analyzing relevant scientific articles. The results of the study showed that a toxic work environment characterized by violence, bullying, tyrannical leadership, unfriendliness, and exclusion had a significant effect on the increase in work stress, psychological pressure, work stress and intention to quit work. Toxic leadership is the main factor in forming an unhealthy work culture. Social support, especially from supervisors, plays a protective role as a protective factor that mediates these negative relationships. Generation Z was found to be more sensitive to injustice and rights violations in the workplace. The study concludes that organizations need to prioritize psychological safety, implement supportive leadership, and provide tangible organizational policies and support to maintain employees' mental health and reduce work stress rates for long-term organizational sustainability.

This study aims to examine the effect of Work-Life Balance and Organizational Commitment on Turnover Intention with Job Stress as a mediating variable among working Master of Management students. This study applies the Job Demands-Resources Model and Social Exchange Theory to explain the relationships among variables. A quantitative approach with a causal research design was employed. The population consisted of 95 working Master of Management students enrolled in 2025, and 50 respondents were selected using purposive sampling. Data were collected through an online questionnaire using a five-point Likert scale and analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results show that Work-Life Balance and Organizational Commitment have significant negative effects on Job Stress, while Job Stress has a significant positive effect on Turnover Intention. However, Work-Life Balance and Organizational Commitment do not directly affect Turnover Intention. Furthermore, Job Stress significantly mediates the effects of Work-Life Balance and Organizational Commitment on Turnover Intention. These findings indicate that reducing job stress is an important mechanism for lowering Turnover Intention among working students. The study contributes to the application of the Job Demands-Resources Model and Social Exchange Theory in the context of working graduate students.

High consumption of sugar-sweetened beverages (SSBs) has become an increasing public health concern, particularly among adolescents. Excessive SSB intake is a major risk factor for various non-communicable diseases, including type 2 diabetes mellitus, cardiovascular diseases, obesity, dental caries, and certain types of cancer. This study aimed to analyze the factors associated with the level of sugar-sweetened beverage (SSB) consumption among adolescents. This study employed a descriptive literature review approach. Data were obtained from national and international journals relevant to the topic of SSB consumption among adolescents. The selected articles were analyzed to identify factors associated with SSB consumption. The findings indicated that SSB consumption among adolescents is influenced by several factors, including individual factors (gender and knowledge), socioeconomic factors (peer influence and pocket money allowance), environmental factors (mass media exposure and beverage availability), and psychological factors (stress level and preference for sweet tastes). This study highlights that SSB consumption is a multifactorial behavior influenced by various interacting determinants. Therefore, comprehensive interventions targeting both individual and environmental factors are needed to reduce SSB consumption among adolescents.

This study aims to analyze the effect of homework load and extended study hours on students’ learning stress levels. The background of this research is based on increasing academic demands that may affect students’ psychological conditions. This study employs a qualitative approach with data collected through observation and interviews. The results indicate that excessive homework load and prolonged study duration significantly contribute to higher levels of learning stress. Students tend to experience physical and mental fatigue, decreased motivation, and difficulty managing time between study and rest. In addition, pressure to achieve high academic performance further exacerbates stress levels. Other factors such as lack of environmental support and less varied teaching methods also influence students’ stress. Furthermore, students often report feelings of anxiety and emotional exhaustion when academic tasks accumulate without adequate rest periods. This condition not only affects their psychological well-being but also reduces concentration and learning effectiveness in the classroom. Therefore, balanced learning load management, appropriate task distribution, and more effective and humanistic teaching strategies are needed to reduce learning stress and improve the quality of education. Schools and educators are encouraged to consider students’ cognitive capacity and mental health in designing assignments and study schedules to create a more supportive learning environment.

Work stress is a critical occupational health concern among midwives working at primary healthcare facilities. This cross-sectional study aimed to analyze factors associated with work stress among 30 midwives, including age, marital status, length of service, and dual-role conflict. Data were collected using structured questionnaires measuring work stress (9 valid items) and dual-role conflict (6 items), and analyzed through univariate, bivariate (Fisher's Exact Test and Chi-Square), and multivariate (binary logistic regression) analyses. Results showed that 43.3% of midwives experienced high work stress and 53.3% reported high dual-role conflict. Bivariate analysis revealed significant associations between work stress and marital status (p=0.009) and dual-role conflict (p=0.004), while age (p=0.633) and length of service (p=0.586) were not significant. Multivariate analysis identified dual-role conflict as the primary determinant of work stress (OR=15.762; 95% CI: 2.149–115.631; p=0.007). Healthcare facility management should develop gender-responsive policies and workplace stress intervention programs to reduce dual-role conflict and work stress among midwives.

This study investigates the critical factors influencing job satisfaction among night shift employees at RSUD KHZ Musthafa Singaparna Tasikmalaya, given the inherent challenges of 24-hour hospital operations. Night shift workers are particularly susceptible to physical and psychological strain, which can elevate job stress and disrupt work-life balance, ultimately threatening their job satisfaction. The research employs a quantitative associative approach, utilizing Likert-scale questionnaires distributed to 75 night shift staff selected through purposive sampling. Data were analyzed using Multiple Linear Regression with SPSS. Instrument validation confirmed that all items were both valid and reliable. Partial regression results reveal that job stress exerts a positive and significant effect on job satisfaction (t = 3.106, Sig. = 0.003), while work-life balance also demonstrates a positive and significant impact (t = 1.815, Sig. = 0.044). Simultaneously, both variables together significantly influence job satisfaction (F = 10.121, Sig. < 0.001), with an RSquare of 0.419, indicating that 41.9% of the variance is explained by the model, while 58.1% is attributable to external factors. These findings underscore the importance for hospital management to actively manage job stress through targeted interventions and design equitable shift scheduling policies. Such strategies are essential to sustaining high levels of employee satisfaction, which in turn supports both staff well-being and the quality of patient care in a demanding healthcare environment.

Background: Menstruation is a natural physiological process that indicates the functional maturity of the female reproductive system. Menstrual cycle disorders can be influenced by several factors, including stress and obesity. Stress may cause hormonal changes through the hypothalamic-pituitary axis, leading to decreased luteinizing hormone (LH) levels and menstrual irregularities. Obesity can also affect ovarian function and disrupt the menstrual cycle. Objective: To determine the relationship between stress and obesity with menstrual cycle disorders among female adolescents at SMAN 1 Majene in 2026. Methods: This study used an analytical observational design with a cross-sectional approach. Data on stress levels, obesity status, and menstrual cycle disorders were collected simultaneously from 84 female respondents. The chi-square test was used to analyze the relationships among variables. Results: The analysis showed a significant relationship between stress and menstrual cycle disorders (p = .006; α < .05). A significant relationship was also found between obesity and menstrual cycle disorders (p = .002; α < .05). Many obese respondents experienced irregular menstrual cycles. Conclusion: There is a significant relationship between stress and obesity with menstrual cycle disorders among female adolescents at SMAN 1 Majene.
