This study evaluates the effectiveness of the Free Nutritious Meal Program (MBG) in improving students' cognitive abilities based on nutritional status in Brangsong Village, Indonesia. The research used a mixed-methods approach, combining quantitative and qualitative designs. Quantitative data were collected from 30 student beneficiaries via questionnaires and analyzed using descriptive statistics and Pearson correlation coefficients. Qualitative data were gathered through in-depth interviews with managers of the Nutrition Fulfillment Service Unit (SPPG), school authorities, students, and parents, and analyzed thematically. The results show a positive and significant relationship between nutritional status and academic achievement, but no significant relationship with students' cognitive ability. Nutrient intake, however, was positively and significantly associated with both cognitive ability and academic achievement. The strongest relationship was observed between cognitive ability and academic achievement. These findings suggest that the MBG program effectively supports academic achievement by improving nutrient intake and cognitive ability. However, its impact on students’ nutritional status has not been uniformly distributed.

Introduction:. Dental caries is one of the most common oral health problems experienced by school-age children. A high prevalence of caries can affect growth and development, nutritional intake, and academic performance. One effective measure to prevent caries is the application of fissure sealants on posterior teeth.Objective:To implement fissure sealants for the prevention of dental caries and to improve students’ knowledge about oral health.Methods:The activities included initial dental examination, oral health education, application of fissure sealants, and evaluation of knowledge through pre-test and post-test among 35 fifth-grade students at UPT SPF SD Negeri Pampang II.Results:The findings showed that 30 students (85.7%) had deep pits and fissures, while 5 students (14.3%) had early caries. After the education session, students with good knowledge increased from 8 students (22.9%) to 27 students (77.1%). All students who met the indications successfully received fissure sealant treatment without complications.Conclusion: The implementation of fissure sealants is effective as a simple preventive measure in preventing dental caries among school-age children and enhances students’ awareness and knowledge of oral health. This program is recommended to be conducted regularly to reduce the risk of caries

Childhood tuberculosis remains a significant public health challenge, particularly in developing countries where malnutrition and limited diagnostic resources increase disease severity and mortality. Children are at high risk of rapid progression from latent infection to active disease due to immature immune systems. We report a case of a 1-year-old girl presenting with cough, fever, shortness of breath, and poor growth. Chest radiograph showed consolidation and infiltrates in the right paracardial area consistent with pulmonary tuberculosis. The patient was treated with first-line anti-tuberculosis drugs, including rifampicin and pyrazinamide, along with nutritional support, resulting in significant clinical improvement and discharge on day eight. This case emphasizes the importance of early recognition and management of tuberculosis in young children with risk factors such as malnutrition and incomplete immunization. Preventive strategies such as BCG vaccination, contact screening, family education, and access to tuberculosis preventive therapy are essential to reduce morbidity and mortality in childhood TB.

Background: Adolescence is a transitional period from childhood to adulthood, with signs of entering adolescence including physical and psychological changes. The adolescent phase is marked by physiological maturation such as the growth of tissues and body organs. This requires adolescents to have sufficient nutritional intake. If the intake is inadequate, it can lead to disturbances in the body's metabolic processes. Nutrient deficiencies, particularly iron (Fe), can cause nutritional anemia. Low hemoglobin levels can occur due to insufficient nutrient intake from food, especially nutrients that support hemoglobin formation. Objective: The objective of this study is to determine the relationship between hemoglobin levels and BMI scores in female adolescents at SMA N 3 Boyolali. Method: The research design was correlational analytic, with a sample of 76 female students at SMA Negeri 3 Boyolali. The sampling technique used random sampling according to inclusion and exclusion criteria. The research instruments included a digital hemoglobinometer, a digital step-on scale, and a microtoa. Data were analyzed using the Spearman Rank test. Results: Bivariate analysis using the Spearman Rank statistical test showed r = 0.343 with a p-value of 0.002 < 0.05, indicating that Ha was accepted. An r of 0.343 is equivalent to 34.3%, indicating a low strength of association. Conclusion: There is a significant relationship between hemoglobin levels and BMI scores in adolescent girls.

Teenage pregnancy remains a reproductive health issue in Indonesia, including in Batam City. According to data from the Batam City Health Office in 2024, there were 18 cases of teenage pregnancy (0.06%) with the Lubuk Baja Health Center being one of the highest areas. Pregnant teenagers are at high risk of complications such as anemia, malnutrition, and low birth weight (LBW), which contribute to high rates of maternal and infant morbidity. This study used a descriptive method with a case study approach on Ny. S, an 18-year-old teenager with a pregnancy in the Lubuk Baja Health Center area of Batam City in 2025. Data collection was conducted through interviews, observations, physical examinations, and SOAP documentation following the 7-step Varney obstetric management. The findings revealed that Ny. S experienced mild complaints such as nausea, reduced appetite, and anxiety about her pregnancy. After three visits, the mother's complaints decreased, appetite improved, anxiety decreased, and nutritional status was within normal limits. Comprehensive midwifery care with a biopsychosocial approach was proven effective in improving both the physical and mental health of pregnant teenagers and preventing pregnancy complications.

Tuberculosis (TB) remains a significant health issue in Indonesia, with the number of cases not showing a decline. Pediatric pulmonary tuberculosis is one of the leading causes of morbidity and mortality. In 2018, the number of TB cases in Aceh reached 41,595, with Aceh Utara having the highest number at 4,819 cases, followed by Bireuen with 3,636 cases, while Sabang recorded the lowest at 272 cases. The primary risk factor for pulmonary tuberculosis in children is a history of contact with adult TB patients, as children's immune systems are still weak, allowing the bacteria to enter their bodies easily. This study aims to examine the history of TB contact in children at the Pediatric Clinic of Cut Meutia General Hospital. The research used a descriptive observational design, with 105 respondents, and data was collected from medical records. The results showed that the majority of respondents were toddlers (47.6%), most were male (54.3%), and 58.1% had good nutritional status. A significant percentage of respondents (77.1%) had a history of contact with TB patients, and 83.8% did not receive BCG vaccination. These findings highlight that contact with TB patients is a key factor in the transmission to children.

Indramayu mango is a seasonal fruit that is highly favored due to its delicious taste and high nutritional content. However, high mango production is often not supported by adequate post-harvest facilities, particularly in terms of fruit ripeness classification. Currently, mango ripeness classification is still performed manually, which tends to be subjective and inconsistent. To address this issue, this study proposes a ripeness detection system for Indramayu mangoes by integrating the TGS2602 gas sensor and the YOLOv11 algorithm based on image processing. The TGS2602 sensor is used to detect ethylene gas emitted by ripe mangoes, while YOLOv11 is employed for visual image analysis of the fruit. This study aims to evaluate the system’s performance in classifying ripe and unripe mangoes, as well as analyze the integration between the gas sensor and the object detection model. The test results show that the TGS2602 sensor can detect increased ethylene gas concentration in ripe mangoes, while YOLOv11 demonstrates high accuracy in detecting mangoes based on visual images, with precision and recall close to 1.0. The system was also tested under various lighting conditions, including dark environments, and still performed well, although with a slight decrease in accuracy under low-light conditions.

Type 2 diabetes mellitus in the elderly significantly impacts quality of life (QoL) due to physiological changes in aging, comorbidities,and the risk of chronic complications. Nutritional management is considered a key intervention to improve glycemic control and functional status in the elderly.Objective: To review the current evidence regarding the effect of nutritional interventions on the quality of life in elderly with type 2 diabetes mellitus through a Literature Review approach.Methods: The Literature Review was conducted by identifying articles from the Scopus database published in 2020–2025. The review process included screening based on inclusion-exclusion criteria, eligibility assessment, and narrative synthesis of relevant studies,including controlled trials,quasi-experimental studies, observational studies, and systematic observations.Results: From the selected studies, interventions with a low glycemic index diet and a balanced diet have been shown to reduce HbA1c levels and the risk of complications; a multicomponent program combining diet and exercise produces synergistic effects on glucose control, physical function,and quality of life.Structured nutrition education (DSME) and family involvement improve satisfaction and metabolic outcomes.The use of technology (mobile apps) shows potential in monitoring intake and glucose,although digital literacy challenges and limited sample size and study design are often limitations.Conclusion: Targeted nutrition interventions, especially when combined with exercise, education,family support,and age-friendly technology,have the potential to improve metabolic control and quality of life in older adults with T2DM.Recommendation: Large-scale RCTs and more robust longitudinal studies are needed to establish the long-term effectiveness and cost-effectiveness of multicomponent nutrition interventions and technology adaptations for older adults with multimorbidity.

Tuberculosis (TB) remains a major global health problem with high morbidity and mortality rates, particularly in high-burden countries such as Indonesia. Nutritional status is one of the important factors influencing the incidence and outcomes of TB. This literature review aims to analyze the relationship between nutritional status and pulmonary tuberculosis based on recent national and international studies. Articles were retrieved from Google Scholar, PubMed, and Portal Garuda using the keywords “nutritional status” and “tuberculosis” as well as “status gizi tuberculosis” within the period of 2019–2024. Eligible articles were analyzed descriptively. The findings indicate that poor nutritional status is significantly associated with an increased risk of pulmonary tuberculosis. Malnutrition impairs cellular immunity, particularly T-lymphocyte and macrophage function, thereby increasing susceptibility to Mycobacterium tuberculosis infection. Conversely, active TB infection can worsen nutritional status through increased energy expenditure, decreased appetite, and metabolic alterations. This bidirectional relationship highlights the crucial role of nutritional interventions in TB prevention and management. Therefore, improving nutritional status should be considered an integral component of tuberculosis control strategies.

This study is based on the need to develop a more effective concentrate ration for lactating dairy cows, as existing formulations in the field are greatly influenced by the availability of ingredients and varying quality. Therefore, this study focuses on optimizing concentrate in dairy cow feed rations to meet SNI standards, which include crude protein (CP), Total Digestible Nutrients (TDN), Calcium (Ca), and Phosphorus (P), with more efficient results in terms of price and nutrition. This study uses the Whale Optimization Algorithm (WOA) metaheuristic approach, which balances the exploration and exploitation processes in finding the best solution to optimization problems. This algorithm has fewer parameters than other metaheuristics such as GA, PSO, and DE. WOA runs naturally in continuous space without the need for genetic operators such as crossover and mutation. The dataset used contains types of dairy cow feed ingredients along with nutritional requirements and prices so that researchers can process the data into efficient feed concentrate that is suitable for lactating dairy cows.

Adolescents are a vulnerable group facing nutritional problems, therefore nutritional needs are crucial. Unhealthy lifestyle changes, such as excessive cigarette consumption, can lead to nutritional status problems. This study aims to analyze the relationship between mental health and cigarette consumption with the nutritional status of male adolescents at SMK Negeri 3 Palu. This study was quantitative, using a cross-sectional approach with a population of adolescents at SMK Negeri 3 Palu aged 16-18 years. This study was conducted in December 2024. The sample size was 103 individuals, using a stratified random sampling technique. Based on the results of the Spearman rank test, it shows that the adolescents who experience the most mental health problems are at a mild level with a nutritional status of 42.6% (p = 0.724) > value ∝ 0.05 and the adolescents who have the most heavy cigarette consumption with a nutritional status of 48.8% (p = 0.221) > value ∝ 0.05, which means there is no relationship between mental health and nutritional status and there is no relationship between cigarette consumption and the nutritional status of male adolescents at SMK Negeri 3 Palu.

Crackers are snacks that are popular with various age groups, but generally have a relatively low calcium content so they do not contribute to meeting daily mineral needs. Therefore, food product innovations are needed to increase their nutritional value, one of which is by utilizing purebred chicken egg shells as a natural source of calcium. This study aims to analyze the effect of purebred chicken eggshell flour substitution on the acceptability of crackers and determine the best formulation as a high-calcium snack. The research method used an experimental design with a Complete Random Design (RAL) consisting of four treatments, namely P0 (100:0), P1 (90:10), P2 (85:15), and P3 (80:20). The testing is carried out qualitatively through organoleptic tests which include color, aroma, taste, and texture. The data was analyzed using the one-way ANOVA test and followed by the Post Hoc Kruskal-Wallis test if there were significant differences. The results showed that the best formulation was found in the P1 treatment with a 10% substitution of eggshell flour. Overall, the substitution of purebred chicken eggshell flour had no significant effect on the acceptability of crackers.

Nutritional status plays an important role in shaping body image among adolescents, particularly female adolescents who experience rapid physical and psychosocial changes. Adolescents with nutritional problems are more likely to feel dissatisfied withitheiribody shape, whichimay lead to unhealthy behaviors such as strict dieting or excessive eating to gain weight. Thisistudy aimed toianalyze theirelationship betweeninutritional statusiand bodyiimage amongifemale adolescentsiat SMK Negeri 1 Palu. This research employedia quantitativeiapproachiwith aicross-sectionalidesign. Aitotal ofi169 femaleistudentsiwere selected using stratified random sampling. Body image data were collected using the Body Self Relation Questionnaire–Appearance Scale, while nutritional status was assessed using Body Mass Index for Age (BMI-for-Age) and Height for Age (HFA). Data were analyzed using the Spearman Rank correlation test. The results indicated that there was no significant relationship between nutritional status based on BMI-for-Age and body image, with a p-value of 0.329. Similarly, no significant relationship was found between Height-for-Age and body image among female adolescents, with a p-value of 0.892. Most respondents were aged 16–17 years, had a negative body image perception, normal BMI-for-Age nutritional status, and normal Height-for-Age category. These findings suggest that body image among female adolescents is not solely influenced by nutritional status but may also be affected by other psychosocial and environmental factors. Therefore, future research is recommended to apply a cohort study design and explore other determinants of body image, such as social media exposure, peer influence, and infectious diseases, to provide a more comprehensive understanding of factors affecting adolescent body image.

Background: Hand grip strength is an essential indicator of physical capacity and nutritional status that can identify obesity risk. Adipose tissue accumulation in central obesity contributes to decreased hand grip strength quality through impaired muscle force transmission. Previous studies showed inconsistent results regarding the relationship between waist circumference and hand grip strength, especially in populations with high physical activity. Objective: To analyze the relationship between waist circumference and hand grip strength in male construction workers with high physical activity in Medan City. Methods: This descriptive-analytic study with cross-sectional design involved 100 male construction workers aged 30-39 years selected using purposive sampling technique. Waist circumference was measured using measuring tape, while hand grip strength was measured using handgrip dynamometer. Data analysis used Chi-Square test with significance level α=0.05. Results: The majority of respondents had normal waist circumference (64%) with mode 70 cm and normal grip strength category (53%) with mode 41.7 kg. Chi-Square test showed significant relationship between waist circumference and hand grip strength (p=0.039). Conclusion: There is a significant relationship between waist circumference and hand grip strength in construction workers. High physical activity does not completely prevent central obesity, therefore nutritional management and health education programs are needed for optimization of body composition and muscle functional capacity.

Anemia in toddlers is a serious nutritional problem that impacts physical growth, cognitive development, and the child's immune system. This study aims to provide an overview of the level of knowledge, attitudes, and practices of parents in preventing anemia in toddlers. This quantitative study involved 50 respondents using a structured questionnaire instrument covering the domains of knowledge, attitudes, practices, and sources of health information. The results showed that respondents' knowledge was in the adequate category; although all respondents (100%) understood the negative impact of anemia on growth and intelligence, only 80% understood the technical definition and clinical symptoms accurately. In the attitude domain, respondents showed a very positive response (100%) to the importance of balanced nutrition and early prevention. Regarding the practical aspect, although regular visits to integrated health posts (Posyandu) reached 100%, the consistency of daily animal side dish intake remained at 80%. An interesting finding showed a shift in information sources, with social media (80%) dominating over direct exposure to information from health workers (40%). This study concluded that there is a gap between positive attitudes and consistent daily practices, and the need to optimize health education through digital media by medical personnel to reduce the incidence of anemia in toddlers.

Stunting is a chronic nutritional disorder characterized by a child’s height being below the age-standard growth curve. One contributing factor is the mother’s knowledge regarding proper complementary feeding (MP-ASI). This study aims to determine the correlation between maternal knowledge of complementary feeding and stunting among children under five at Posyandu in the Bangetayu Health Center working area, Semarang. This research employed an analytical observational design with a case-control approach. A total of 60 respondents were selected using purposive sampling, consisting of 30 stunted and 30 non-stunted children. Data were collected using a structured questionnaire and analyzed using the Chi-Square test. The findings indicated that most mothers possessed good knowledge of complementary feeding (80%). Stunting prevalence among respondents was 41.7%. The Chi-Square test revealed a p-value of 0.000 (p < 0.05), demonstrating a significant relationship between maternal knowledge of complementary feeding and stunting. Mothers with poor knowledge were more likely to have stunted children compared to those with adequate understanding. These results highlight the crucial role of improving maternal nutrition knowledge to prevent stunting and support optimal child growth and development.

Low levels of maternal knowledge and appropriate nutritional practices, combined with limited continuity of nutrition education from health workers, remain significant risk factors for maternal and child health problems, including stunting. The GEMPITA Program (Gerakan Edukasi MPASI Tepat dan Aman / Safe and Appropriate Complementary Feeding Education Movement) was implemented as a community service initiative to improve nutritional knowledge, skills, and practices among families in the working area of Teratak Public Health Center. The program employed structured methods, including socialization, education, training, demonstrations, mentoring, and non-formal monitoring and evaluation. The target participants were mothers with children aged 6–24 months, as well as health workers and community health cadres. Program effectiveness was assessed using pretest posttest measurements and direct observation of behavioral changes. The results demonstrated a significant improvement in maternal knowledge regarding appropriate complementary feeding, enhanced skills in age-appropriate food preparation, and improved hygienic and nutritious feeding practices. In addition, the capacity of health workers to deliver nutrition education was strengthened. Overall, the GEMPITA Program proved effective in improving family nutrition practices and reinforcing the role of the public health center in stunting prevention through a sustainable community empowerment approach.

Background: Preschool age, which is 4-6 years, is a crucial stage in child development. Delays in development and growth in children will have long-term impacts on their cognitive, social, and emotional abilities. Children's diet and parenting styles are greatly influenced by their growth and development. Objective: This study aims to examine how parenting styles and nutritional status are related to the development of preschool children. Method: This study used a quantitative approach with a cross-sectional design and involved fifty parents of preschool children aged between 4 and 6 years. Total sampling was used as the sampling technique. To conduct bivariate analysis, researchers used the Spearman rank correlation test. PSDQ or Parenting Styles and Dimensions Questionnaire was used to collect data on parenting styles, Denver Developmental Screening Test II (DDST II) was used to assess child development, and Z scores were used to determine the child's nutritional status. Results: The majority of respondents indicated an authoritative (democratic) parenting style (88%), good nutritional status (88%), and normal child development (80%). There was a significant correlation between parenting style and child development, with p = 0.004 and r = 0.405. Meanwhile, for nutritional status and child development, the p value was 0.013 with r = 0.351. Conclusion: Nutritional status and democratic parenting style were significantly correlated with preschool children's development. Education on balanced parenting and nutrition needs to be strengthened through family-based nursing interventions.

Background: The prevalence of Chronic Energy Deficiency (CED) among pregnant women in West Papua remains very high, reaching 40.7%. The provision of manufactured supplementary food (PMT) in the form of biscuits often faces challenges due to low compliance caused by monotonous taste and nausea-triggering flavors. Sweet potato (Petatas) is a potential local food source with an energy content of 123 kcal/100g that could serve as an alternative PMT. Objective: To analyze the acceptability (taste, color, aroma, and texture) of sweet potato-based PMT products among pregnant women with CED. Methods: A quantitative study with a cross-sectional design was conducted from September to October 2025 at the Ransiki Health Center. The sample consisted of 22 pregnant women with CED. The research instrument used a 5-point hedonic scale questionnaire. Results: Respondent characteristics were dominated by the ideal age range of 20-35 years (81.8%) and low family income (63.6%). The acceptability test results showed high overall acceptance with an average score of 4.23 (Highly Liked). The color attribute obtained the highest score (4.27), followed by taste (4.18), texture (4.18), and aroma (4.14). Conclusion: Sweet potato-based PMT products have excellent acceptability and significant potential to be integrated into local nutritional intervention programs for pregnant women with CED.
