Anemia is a condition with hemoglobin and erythrocyte levels lower than normal, which is 12 grams/dl for adolescents. Iron deficiency anemia in adolescent girls is at higher risk because it causes a decrease in immunity, making them susceptible to health problems. One of the causes is the lack of knowledge of adolescent girls about healthy lifestyles and self-motivation regarding the importance of balanced nutrition in preventing anemia. The purpose of this study was to determine the effect of education on the level of knowledge of adolescent girls about anemia. The type of research used was quantitative research with a quasi-experimental research design with a pre-test-post-test research design. The sample consisted of 90 adolescent girls. The results showed that before being given education, the majority of respondents were in the sufficient category (45.6%), while after being given education, the majority were in the good category (84.4%). The results of this study showed that there was a significant difference in the level of knowledge of adolescent girls about anemia before and after being given education with a significance value of 0.000, which means there was a significant effect of education on the level of knowledge of adolescent girls about anemia.

This study examines the role of Artificial Intelligence (AI) in enhancing student collaborative learning, with a particular emphasis on AI-driven feedback mechanisms and patterns of student interaction in developing effective collaborative skills. Unlike prior studies, this research highlights the mediating effect of AI-driven feedback on teamwork efficiency and overall learning outcomes in collaborative environments. An explanatory quantitative approach was applied using Partial Least Squares Structural Equation Modeling (PLS-SEM) to ensure robust data analysis. Data were collected from 112 university students who were actively engaged in AI-assisted collaborative learning activities, using a structured online survey instrument. The data were subsequently analyzed using SmartPLS software. The results reveal that AI significantly enhances student interaction (β = 0.534, p < 0.000) and improves problem-solving feedback (β = 0.620, p < 0.000), both of which contribute to significantly strengthening collaborative skills (β = 0.716, p < 0.000). However, the findings also indicate that AI alone does not directly improve collaboration without the support of structured pedagogical design and guidance. Therefore, universities should strategically integrate AI-driven feedback into Learning Management Systems (LMS) and strengthen digital literacy initiatives to optimize the effectiveness and sustainability of AI in collaborative learning contexts.

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.

This study aims to know the decision-making strategies in individuals with pragmatic personality. The approach used was qualitative with a case study method. The subjects of the study consisted of three individuals who were selected using purposive sampling techniques based on pragmatic personality characteristics, i.e. oriented to results, efficiency, and practical considerations in decision making. Data were collected through semi-structured interviews and observations, then analyzed using thematic analysis. The results of the study showed that all three respondents had relatively similar decision-making patterns, namely starting with understanding the problem, followed by identification and evaluation of multiple alternatives, as well as considering the advantages and disadvantages of each option. In determining the final decision, pragmatic individuals tend to choose solutions that are realistic, simple, effective, and have the lowest risk yet provide the optimal benefit. Additionally, in the face of important decisions, respondents showed a cautious attitude by calming themselves, not rushing, as well as partially considering the opinions of others as additional evaluation material. Overall, the findings of this study suggest that pragmatic personality plays a role in forming logical, adaptive, and real outcome-oriented decision-making strategies in daily life.

Employee attendance is an important indicator to demonstrate the discipline and performance of village employees. The process of recording employee attendance previously at the Lumban Dolok Village Office was still done manually. This can cause problems such as incorrect data, slow report collection, and absenteeism. Therefore, the purpose of this study is to develop a web-based presence-monitoring information system that uses the Location-Based Service (LBS) method. The purpose of the LBS method is to ensure that the attendance process can be carried out only when employees are within a specified radius of the Lumban Dolok Village Office. This system uses latitude and longitude data from the user's device to calculate the geographic distance to the location's center point. The developed system uses the user's device's latitude and longitude to calculate the distance between the employee's location and the attendance center. Within a radius of 25 meters, the attendance process can only be carried out if the employee is within that radius; if they are outside the radius, then the attendance will be automatically rejected by the system. In this study, the waterfall system development method was employed, with PHP and UML. The results of the study show that this system can help the village office monitor employee attendance directly, speed up the collection of attendance reports, and reduce the risk of data manipulation. In addition, attendance reports are easily accessible by admins and village heads to assess employee performance. Thus, the web-based attendance information system using the LBS method is expected to improve compliance, transparency, and effectiveness of attendance management at the Lumban Dolok Village Office.

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.

Dengue Hemorrhagic Fever (DHF) remains a significant public health problem in tropical countries, including Indonesia. The presence of Aedes aegypti larvae is an important indicator of dengue transmission risk and is influenced by environmental factors, particularly temperature and humidity. This study aimed to analyze the relationship between temperature and humidity and the presence of mosquito larvae in Meteseh Village, Tembalang District, Semarang City. This analytical observational study employed a cross-sectional design involving 100 households selected through quota sampling. Data were collected through direct observation and measurement of temperature and humidity using a thermo-hygrometer, then analyzed using the Chi-square test. The results showed a significant association between temperature and the presence of mosquito larvae (p=0.000), while humidity was not significantly associated with larvae presence (p>0.05). Temperature was identified as a more influential environmental factor in supporting mosquito larvae existence than humidity in the study area. These findings highlight the importance of environmental-based vector control strategies, particularly through management of microhabitat temperature conditions, to support dengue prevention.

Iron deficiency anemia remains a major public health problem among pregnant women in Indonesia, with a national prevalence of 37.1% and higher rates in regions such as Brebes Regency. Adequate nutritional knowledge and sufficient iron intake are expected to prevent decreases in hemoglobin (Hb) levels during the third trimester. This study aimed to analyze the relationship between nutritional knowledge, iron intake adequacy, and Hb levels among third-trimester pregnant women at Puskesmas Brebes. An analytic observational study with a cross-sectional design was conducted on 62 respondents using total sampling. Data were collected through a nutritional knowledge questionnaire, a Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ) to assess iron intake based on the Recommended Dietary Allowance of 27 mg/day, and Hb measurement using a digital device. The prevalence of anemia was 32.3%, with a mean Hb level of 11.25 ± 1.74 g/dL. Most respondents had high nutritional knowledge (72.6%), but 79.0% had inadequate iron intake. Chi-Square analysis showed no significant relationship between nutritional knowledge and Hb levels (p=0.109) or between iron intake adequacy and Hb levels (p=0.426). Other factors, including iron absorption inhibitors, compliance with iron supplementation, nutritional status, and limited sample size, may have influenced the results.
