Increased caffeine intake is commonly used by students to cope with academic demands, especially during examinations and the completion of final projects. Excessive caffeine consumption may affected sleep quality and potentially influence nutritional status. This study aimed to determine the correlation between caffeine intake, sleep disturbances, and nutritional status among final – year unsergarduated students at Dr. Soekardjo University. This study used quantitative approach with an observational analytic and cross-sectinal design. A total of 108 students participated in the study. Data were collected using questionnaires and analyzed using the Spearman Rank correlations test. The findings indicated that the most of respondents with low caffeine intake experienced mild sleep disturbances, totaling 56 respondents (80%). Meanwhile, respondents with moderate and high caffeine intake mostly experienced moderated sleep disturbances, with 13 respondents (61.9%) and 9 respondents (52.9%), respectively. The results showed a significant correlation between caffeine intake and sleep disturbances (p-value=0.000). In all categories of caffeine intake, most respondents had normal nutritional status. However, no significant relationship was found between caffeine intake and nutritional status (p-value=0.351). In conclusion, caffeine intake was associated with sleep disturbances but not with nutritional status among final-year undergraduate students.

Microplastics are extremely small plastic particles that have become a major concern in public health and environmental studies. This literature review aims to discuss the sources of microplastics, their routes of exposure to the human body, their distribution in organs, and their potential health impacts. The method used was a literature review of scientific articles and reports published from 2021 onward, retrieved from Google Scholar, PubMed, ScienceDirect, and official websites of organizations such as the WHO, OECD, and the World Bank. The review findings show that microplastics originate from plastic waste, synthetic clothing, cosmetics, vehicle tires, and food packaging. These particles have been detected in blood, lungs, the placenta, feces, and various human tissues, indicating that human exposure is widespread. However, evidence from human studies is still limited, so cause-and-effect relationships cannot yet be confirmed with certainty. Based on these findings, further research is needed to better understand the long-term health effects of microplastics. In addition, efforts to reduce single-use plastics, improve waste management systems, and increase public education are essential to reduce exposure and prevent future health risks.

Sleep duration and sleep quality are essential physiological needs that play a significant role in the emotional and behavioral development of children aged 3–6 years. Adequate sleep supports brain development, cognitive functioning, emotional regulation, and social interaction skills in early childhood. Conversely, poor sleep duration and low sleep quality may negatively affect children’s attention, mood stability, and ability to interact socially with peers and caregivers. This article is a literature review using a systematic review approach that analyzes 10 scientific articles published between 2016–2026 to evaluate the relationship between sleep duration and sleep quality with emotional and behavioral problems in preschool children. The article selection process followed the PRISMA flow diagram, with articles sourced from Google Scholar, PubMed, and ScienceDirect databases. The findings consistently indicate that inadequate sleep duration and poor sleep quality are associated with increased emotional and behavioral problems, including hyperactivity, anxiety, emotional dysregulation, and difficulties in social interaction among children. Furthermore, sleep disturbances were found to negatively influence children’s emotional self-regulation abilities, which are crucial for adaptive behavior. Therefore, ensuring adequate sleep duration and improving sleep quality are important strategies to support optimal emotional and behavioral development in preschool-aged children.

This study was conducted based on the crucial role of diesel generator engines as the primary source of electrical power on board ships, making their operational reliability essential. One of the factors influencing generator engine performance is lubricating oil temperature. Excessive lubricating oil temperature may reduce lubrication effectiveness, increase friction between moving components, and lower engine efficiency. Therefore, this research aimed to identify the causes of high lubricating oil temperature in diesel generator engines and determine appropriate corrective actions. The study employed a descriptive quantitative approach. Data were collected through direct observation, interviews, and documentation during sea practice aboard MV. CL FLANDERS from 4 July 2024 to 5 July 2025. The data were analyzed using simple linear regression to examine the relationship between generator load and lubricating oil temperature. The findings revealed that generator load had a significant effect on the increase in lubricating oil temperature. Under normal operating conditions, the lubricating oil temperature ranged from 60°C to 72°C, while under abnormal conditions it increased to between 68°C and 81°C. The abnormal rise in temperature was mainly caused by cooling system problems, particularly a dirty LO cooler, scale deposits on the sea water pump impeller, and blockage in the cooling capillary pipes. The regression equation under normal conditions was Y = 45 + 0.30X, whereas under abnormal conditions it was Y = 53.5 + 0.30X. Elevated lubricating oil temperature resulted in lower oil viscosity, higher fuel consumption, and reduced diesel generator engine performance. Therefore, regular maintenance of the LO cooler, sea water pump, and continuous temperature monitoring are necessary to maintain optimum engine performance.

This study aims to analyze the implementation of the Bravo PUPR Online attendance system in improving the work discipline of Civil Servants (ASN) at the National Road Implementation Center of East Nusa Tenggara. The research focuses on punctuality of attendance, consistency in fulfilling working hours, task completion, compliance with attendance procedures, alignment between recorded data and actual conditions, and acceptance of consequences for violations. The study employs a qualitative approach with data collection techniques including observation, documentation, and interviews with leaders, system operators, and ASN as direct users. The results indicate that the implementation of the Bravo PUPR Online attendance system has improved administrative order in attendance and increased ASN awareness of time discipline. However, work discipline has not been fully optimal, as several issues remain, such as inconsistent attendance, suboptimal fulfillment of working hours, and discrepancies between attendance data and actual field conditions. In addition, technical constraints such as internet connectivity and GPS accuracy, as well as behavioral factors like negligence and lack of supervision, also affect system effectiveness. In terms of compliance, the Bravo system integrated with e-HRM is considered effective in detecting violations and enforcing strict consequences, ranging from warnings to administrative sanctions. This demonstrates that the attendance system functions not only as a recording tool but also as an instrument for monitoring discipline.

Low Birth Weight (LBW) refers to infants born with a birth weight of less than 2,500 grams and remains an important issue in neonatal health due to its association with increased neonatal morbidity and mortality. To analyze the determinants of LBW based on primary studies published from 2021 to 2026. A literature review was conducted using the PRISMA approach. Article searches were performed through PubMed, Google Scholar, Scopus, ScienceDirect, and ProQuest using the keywords low birth weight, determinant factors, risk factors, BBLR, and faktor risiko with Boolean operators AND/OR. The inclusion criteria were primary studies, full-text availability, publication in Indonesian or English, and publication years from 2021 to 2026. A total of 20 articles were included, consisting of 15 international articles and 5 national sources. The review showed that LBW is influenced by interrelated maternal, nutritional, obstetric, and sociodemographic factors during pregnancy. The most dominant factors included multiple pregnancy with an adjusted OR of 21.74, maternal food insecurity with an AOR of 6.85, maternal hemoglobin level <11 g/dL with an AOR of 5.21, lack of iron-folic acid supplementation with an AOR of 4.17, maternal age ≤20 years with an AOR of 3.42, pregnancy interval <1 year with an adjusted OR of 2.92, missed antenatal care visits with an AOR of 2.74, smoking during pregnancy with an OR of 2.18, and maternal hypertension with an AOR of 1.94. LBW is influenced by multiple interrelated factors; therefore, efforts to reduce its incidence should focus on evidence-based interventions, particularly through optimizing antenatal care services, improving maternal nutritional status, and early detection of pregnancy.

This study was conducted in response to the increasingly complex nutritional issues among adolescents, reflected in the coexistence of undernutrition and overnutrition within the same population, which are closely associated with dietary consumption patterns. The research aimed to investigate the relationship between diet quality and the nutritional status of students at SMAN 9 Surabaya. A quantitative approach with a cross-sectional design was employed, involving 85 participants selected based on the estimated sample requirement for correlation analysis. Dietary intake data were collected using two non-consecutive 24-hour food recalls and subsequently assessed using the Diet Quality Index for Adolescents (DQI-A). Nutritional status was determined through BMI-for-age calculations in accordance with the World Health Organization standards. Data analysis was performed using correlational testing and Chi-Square analysis to identify differences in proportions. The findings revealed that the respondents’ diet quality remained suboptimal, while most students were categorized as having normal nutritional status, although cases of undernutrition and overnutrition were still identified. A significant association was found between diet quality and nutritional status (p = 0.001), indicating that better diet quality tended to be linked with normal nutritional status. Based on the DQI-A components, dietary quality demonstrated a significant relationship with nutritional status (p = 0.007), whereas dietary diversity (p = 0.597) and dietary equilibrium (p = 0.507) showed no significant associations. These findings highlight that diet quality, particularly food selection patterns, plays an important role in determining adolescent nutritional status. Therefore, improving nutritional conditions requires more intensive nutrition education interventions focusing on healthy food choices, increased fruit and vegetable consumption, and controlled intake of sugar, salt, and fat, supported consistently by both individuals and the school environment.

Old age is the final phase in the human life cycle, characterised by a decline in physiological function. Global data shows that the prevalence of old age will increase from 33.69 million to 48.19 million by 2035. One of the effects of this decline in physiological function is a disruption in the quality of sleep among the elderly. As many as 50-60% of elderly people in Indonesia experience sleep disorders. One way to overcome sleep disorders is through relaxation therapy. Progressive Muscle Relaxation is a technique performed by stretching and relaxing certain muscles to relax the body. The purpose of this study was to determine the effectiveness of progressive muscle relaxation on the quality of sleep in elderly people. This research method involved a nursing care process from assessment to evaluation using a case study design. The research sample consisted of one elderly person with moderate sleep quality. The intervention was given for 10-15 minutes using eight movements with a frequency of twice a week for one month. The data were analysed using pre-test and post-test PSQI questionnaires to determine sleep quality. The results of this study indicate that progressive muscle relaxation training has an effect on improving sleep quality in the elderly.

The method used is a case study with a nursing process approach, including assessment, nursing diagnosis, planning, implementation, and evaluation. Interventions focus on hallucination management, psychoeducation, and caregiver involvement in care. The results show an increase in patients’ and families’ knowledge regarding the illness and its treatment, improved medication adherence, and enhanced patient ability to control responses to auditory hallucinations. Caregiver involvement has been shown to assist in supervision and providing support to patients. Therefore, comprehensive psychiatric nursing care through hallucination management, psychoeducation, and caregiver involvement is effective in improving medication adherence and controlling symptoms in patients with auditory hallucinations.

This study aims to examine the application of artificial intelligence (AI) in learning to write scientific papers and its impact on the level of originality of students in the Indonesian Language and Literature Education Study Program (PBSI) Semester VI at Bina Bangsa University. This study uses a qualitative method with a descriptive approach, which was conducted through reference searches and interviews with 30 of the total 35 students. The results of the study indicate that AI is utilized functionally as an aid in the writing process, such as compiling outlines, paraphrasing, developing ideas, and reviewing writing. Based on the interview results, the use of AI platforms is dominated by Chat GPT at 50%, followed by Perplexity at 27%, and Gemini.ai at 23%. These findings indicate that students do not rely on a single platform, but rather utilize various technologies adaptively according to their needs. In terms of discussion, the use of AI has a positive impact in the form of improved writing quality, time efficiency, development of creative ideas, increased digital literacy, and the provision of instant feedback. However, there are also challenges that arise, such as the potential for decreased originality, dependence on AI, the risk of violating academic ethics, information bias, and data privacy issues. Therefore, AI should be used as a tool, not a substitute for students' critical thinking skills. This research emphasizes the importance of using AI wisely, critically, and responsibly so that students can produce original, high-quality, and integrated scientific work in the digital age.

This study examines changes in nutritional knowledge, dietary patterns, nutrient intake, and food acculturation among first-year migrant and non-migrant students. A 5 months prospective cohort design was employed involving 32 students from the Faculty of Public Health, Universitas Airlangga. Students were randomly divided equally into migrant and non-migrant groups. Data were collected using questionnaires, food frequency questionnaires, 3×24-hour food recall, and analyzed using descriptive and inferential statistics. The findings indicated no significant differences or changes in nutritional knowledge between groups throughout the observation period (p > 0.05). However, dietary patterns varied, with migrant students showing increased consumption of practical and fast foods. Nutrient intake, particularly energy and protein, was initially lower among migrant students but improved significantly over time, reflecting adaptation to a new environment. Food acculturation was evident among migrant students, with a significant increase in scores during the study period (p = 0.007), indicating gradual adjustment to local eating habits. These results highlight the influence of environmental adaptation on students’ dietary behavior and emphasize the need for targeted nutrition interventions to promote healthy eating habits during the early university transition.
