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.

Electrolytes are essential minerals that play a critical role in various physiological processes within the body, including the maintenance of fluid balance, proper neuromuscular function, and the transmission of nerve impulses. They are vital for the stability of the heart and other crucial organs. When electrolyte levels become imbalanced, as seen in conditions such as hyponatremia (low sodium), hypernatremia (high sodium), hypokalemia (low potassium), hyperkalemia (high potassium), and hypocalcemia (low calcium), serious health issues can arise. These imbalances can result from factors like malnutrition, excessive losses through the kidneys or gastrointestinal tract, hormonal disorders, and certain systemic diseases. Understanding the underlying pathophysiological mechanisms and clinical manifestations of these disturbances is essential for effective diagnosis and treatment. Healthcare providers must identify the root causes of electrolyte imbalances while assessing their severity to implement appropriate management strategies. This often involves gradually correcting electrolyte levels to mitigate the risk of life-threatening complications such as arrhythmias, cerebral edema, and neurological impairment. By fostering a comprehensive understanding of electrolyte imbalances, healthcare professionals can improve diagnostic accuracy and therapeutic effectiveness, ultimately leading to better patient outcomes. This knowledge is crucial in minimizing morbidity and mortality associated with these disruptive conditions, ensuring that individuals receive prompt and effective care to restore balance and maintain overall health.

Background: Breastfeeding is a crucial practice that provides optimal nutrition and immunity for infants while supporting maternal health. However, inadequate knowledge and limited understanding about the importance of breastfeeding often lead to low motivation among pregnant women in preparing for breastfeeding. Providing structured education is expected improve pregnant women’s readiness and commitment to breastfeeding after childbirth. Objective: This study aimed to determine the effect of providing education about the importance of breastfeeding on the motivation of pregnant women in preparing to breastfeed at the Paguat Community Health Center UPTD. Methods: This study employed a pre-experimental design with one-group pretest–posttest approach. A total of 30 pregnant women were selected as the sample using purposive sampling techniques. Data on mothers’ motivation to prepare for breastfeeding were collected before and after the educational intervention using a structured motivation questionnaire. The data were analyzed using the Wilcoxon signed-rank test to assess differences in motivation levels before and after the intervention. Results: The results of the Wilcoxon signed-rank test showed a p-value of 0.000 (p < 0.05), indicating a statistically significant effect of breastfeeding education on the motivation of pregnant women in preparing breastfeed. The findings demonstrate that educational interventions significantly increased maternal motivation following the provision of education. Conclusion: Providing education about the importance of breastfeeding has a significant positive effect on the motivation of pregnant women in preparing to breastfeed. Therefore, breastfeeding education should be strengthened and routinely implemented during antenatal care services to improve maternal readiness and support successful breastfeeding practices.

Toxoplasmosis is a disease transmitted from animals to humans, caused by the protozoan parasiteToxoplasma gondii. The Toxoplasma gondii parasite has infected more than 60% of the world's population and2-51% in Indonesia. Women of childbearing age (15-45 years) are one of the risk groups for the transmission of infection by the Toxoplasma gondii parasite. A person's knowledge is influenced by various factors such as level of education, information, environment and culture. The purpose of this study was to compare the level of knowledge on prevention of toxoplasmosis in women of childbearing age in Lhokseumawe City. This research is a type of descriptive analytic research with a cross-sectional time approach. Samples were taken using a purposive sampling technique from women of childbearing age in Uteunkot Village and Kuala Meuraksa Village. The sample size was determined using the Snedecor & Cochran formula and the minimum sample size was 62 respondents in Uteunkot Village and 62 respondents in Kuala Meuraksa Village. The results of this study indicate that the majority of respondents in Uteunkot Village have a less knowledge level of 43.5% and the majority of respondents in Kuala Meuraksa Village also have a less knowledge level of 85.5%. Data analysis used the Mann-Whitney test. The results of statistical analysis showed a p value <0.05. The conclusion of this study is that there are differences in knowledge of toxoplasmosis prevention in women of childbearing age in rural villages and urban villages.

The challenges of modernity, including the secularization of knowledge, the fragmentation of values, and the increasingly pragmatic and utilitarian orientation of education, require a fundamental renewal of Islamic educational philosophy. In practice, Islamic education is often confined to normative and textualistic approaches that emphasize the transmission of doctrinal knowledge, which limits its responsiveness to social dynamics, scientific developments, and contemporary needs. This condition weakens the critical capacity of Islamic education in shaping individuals who are faithful, rational, and morally integrated. Accordingly, this study aims to examine Islamic educational philosophy from the perspective of critical thought reconstruction as an effort to address the challenges of modernity without shifting the fundamental principles of faith that serve as its normative foundation. This study employs a theoretical research approach through library research, using qualitative analysis of academic books, peer-reviewed journal articles, and relevant scholarly works on Islamic educational philosophy and critical thought. The analysis focuses on the ontological, epistemological, and axiological dimensions of Islamic education within the framework of critical reconstruction. The findings indicate that the reconstruction of Islamic educational philosophy is both an epistemological and practical necessity in responding to modern challenges. This reconstruction is not directed toward the domain of ʿaqīdah, which is qaṭʿī and normative in nature, but rather toward renewing modes of thinking, operational value systems, and educational practices. Consequently, Islamic education should function not merely at a normative level but as an effective instrument for individual and social transformation.

Umbilical cord infection remains one of the major causes of morbidity and mortality among newborns, particularly in areas where knowledge and health practices are still limited. Padellegan Village is one of the regions where some mothers continue to practice traditional cord care methods, such as using herbal mixtures or non-sterile materials, which increases the risk of omphalitis. Initial situation analysis indicates that 40–60% of postpartum mothers are not yet familiar with the principles of clean and dry cord care (dry cord care), and access to accurate health information is still limited. Based on this condition, education on umbilical cord care is essential to improve mothers’ and health cadres’ understanding and skills in preventing neonatal infections. This community service activity focuses on providing evidence-based education regarding safe cord care techniques, infection risk factors, and danger signs that need to be recognized. Padellegan Village was selected due to the high need for maternal–neonatal health education and the low level of community knowledge related to cord care. This activity is expected to bring positive changes, such as improved maternal behavior in performing proper cord care, reduced use of unhygienic traditional methods, and strengthened roles of health cadres in monitoring neonatal health. Enhancing appropriate cord care practices can reduce the risk of infection in newborns, thereby contributing to improving the overall health status of the community in Padellegan Village.

The utilization of biopore infiltration holes has become one of the simple and effective innovations in environmental management and soil resource conservation, with great potential to support a healthy environment. This community service activity aims to enhance farmers' understanding of the use of biopore infiltration holes as an effort for soil and water conservation as well as sustainable organic waste management. The outreach was conducted on September 7, 2024, at the Kesambi Village Hall, Pucuk District, Lamongan Regency, targeting 12 members of the farmer group. The implementation method of the activity included preparation stages, conducting a pretest, delivering material along with interactive discussions, and concluding with a posttest as an evaluation of the participants' understanding improvement. The results of the activity indicate an increase in the average knowledge score of participants from 81.25 in the pretest to 97.92 in the posttest. This demonstrates that the socialization method applied was effective in enhancing farmers' understanding of the functions, production techniques, and benefits of biopores. This activity is expected to encourage the independent implementation of biopores by farmer groups, both at the household and agricultural levels, as part of environmentally friendly and sustainable land management practices.

The third trimester of pregnancy is a challenging period since pregnant women experience various physical and psychological changes that can affect their readiness for childbirth. High anxiety levels and the presence of pregnancy complications are known to reduce maternal preparedness for labor. This study aims to determine the relationship between anxiety levels and pregnancy complications with the readiness of third trimester pregnant women in facing childbirth in the working area of Benteng Community Health Center, Selayar Islands Regency. This research used a quantitative approach with a correlational design and a cross-sectional method. The population consisted of all third trimester pregnant women, with a total sample of 86 respondents selected using purposive sampling. The research instruments included an anxiety questionnaire using the Hamilton Anxiety Rating Scale (HARS), a pregnancy complication checklist, and a childbirth readiness questionnaire. Data were analyzed using the Chi-Square test and multiple logistic regression at a significance level of α = 0.05. The results of the study showed no significant relationship between anxiety and readiness for childbirth (p < 0.550) or between pregnancy complications and readiness for childbirth (p < 0.690). Therefore, it can be concluded that anxiety and pregnancy complications are not significantly related to the readiness of pregnant women in the third trimester for childbirth. This indicates that maternal readiness is influenced by factors other than the variables studied, such as knowledge, family support, and previous childbirth experiences.

Clean and Healthy Living Behavior (PHBS) is a promotive and preventive effort aimed at improving the level of public health. The Baduy indigenous community in Leuwi Damar, Kanekes Village, Lebak Regency, Banten Province has local wisdom and traditional lifestyles that influence daily health practices. However, limited access to information and health services is a challenge in implementing PHBS optimally. This article aims to describe the implementation of PHBS education in the Baduy Leuwi Damar community and its impact on community knowledge and attitudes. The method used is a descriptive approach with educational activities through counseling, discussion and simple demonstrations adapted to local culture. Educational material includes personal hygiene, clean water management, environmental sanitation, and healthy living behavior in daily life. The results of the activity showed an increase in public understanding regarding the importance of personal and environmental hygiene, as well as the emergence of a positive attitude towards implementing PHBS without eliminating the traditional values adhered to. PHBS education carried out using a simple cultural and communication approach is considered effective in increasing the health awareness of the Baduy community. Therefore, health education programs based on local wisdom need to continue to be developed as a strategy to improve the health of indigenous communities. .(Riset Kesehatan Dasar,2019).

The coverage of Complete Basic Immunization (Imunisasi Dasar Lengkap or IDL) in Maharani Village remains low at 38.8%, falling short of the national target of 95%. This condition increases the health risk of toddlers contracting Vaccine-Preventable Diseases (PD3I). This study aimed to determine the relationship between mothers' knowledge and husbands' support regarding the completeness of basic immunization for toddlers in Maharani Village, within the working area of Rumbai Bukit Public Health Center. This research employed a quantitative analytic method with a cross-sectional design. The population in this study comprised all mothers with toddlers in the area, with a sample of 73 respondents selected using the purposive sampling technique. Data collection was conducted using validated questionnaires and observation of Maternal and Child Health (KIA) books, followed by univariate and bivariate analysis using the Chi-square statistical test. The results indicated that the majority of toddlers had incomplete immunization status (61.6%), mothers had a low level of knowledge (61.6%), and respondents did not receive support from their husbands (58.9%). Statistical test results confirmed a very significant relationship between mothers' knowledge (p-value = 0.000) and husbands' support (p-value = 0.000) with the completeness of basic immunization. The conclusion confirms that knowledge and husband's support are the main determinant factors. It is suggested that Rumbai Bukit Public Health Center implement a more inclusive health promotion strategy by involving the active role of husbands in monitoring child health.

Rapid developments in the Artificial Intelligence (AI) industry have triggered an increased need for workers with specialized competencies, which has implications for significant variations in salary levels. This research aims to analyze the factors that influence salaries in the AI sector using the multiple linear regression method. The dataset used includes 15,000 AI job vacancies with variables including job and company characteristics. The data was engineered via the one-hot encoding method and divided into two parts: training data (80%) and test data (20%). The analysis results show that the regression model is able to explain 85% of the variation in salary, with an R² value of 0.85 and a Root Mean Square Error (RMSE) of USD 23,221. The three main factors identified as having a significant influence on salaries in the AI field are work experience, company location, and the industry in which the company operates. The experience factor reflects the skills and knowledge developed over many years, which can increase productivity (Rony et al., 2023). Company location also plays an important role, as the cost of living and demand for skilled labor varies by region (Badran, 2019). Additionally, the specific industry in which an employee works influences salary, given that more developed industries can often offer higher compensation (Huang, 2025). This research makes a significant empirical contribution to the understanding of compensation structures in the AI labor market.

Breast cancer is one of the leading causes of death among women, largely due to delayed diagnosis. Early detection through Clinical Breast Examination (CBE/SADANIS) is an important strategy to identify breast cancer at an early stage. However, the level of knowledge and awareness of Women of Reproductive Age regarding SADANIS remains low. This Community Service activity aimed to improve knowledge and awareness of SADANIS among Women of Reproductive Age through health education at PMB Rama Agustina. The activity was conducted through preparation, implementation, and evaluation stages. Health education was delivered using interactive lectures and discussions, supported by educational media such as leaflets and posters. Evaluation was carried out using pre-test and post-test questionnaires to assess changes in participants’ knowledge. The results showed an improvement in participants’ knowledge and a positive change in attitudes toward the importance of early breast cancer detection. In addition, participants demonstrated increased interest and willingness to undergo SADANIS examinations, either at the midwifery practice or at nearby primary healthcare centers. In conclusion, this activity was effective as a promotive and preventive effort to support early detection of breast cancer among women of reproductive age.

Maternal reproductive health is a critical factor in reducing Maternal Mortality Rate (MMR) and Infant Mortality Rate (IMR). Data from Deli Tua Primary Health Center shows that K4 coverage reached only 78% with prenatal class participation at 40%, still below the national target. Low knowledge among pregnant women about reproductive health is one of the main causes. This Community Service Student Creativity Program (PKM-M) aims to improve reproductive health knowledge through innovative and interactive prenatal class improvement. The implementation method includes developing educational media (modules, posters, videos), conducting classes with participatory learning methods, and evaluation through pre-post tests. The program was conducted over 5 months targeting 30 pregnant women divided into 3 groups, each attending 6 sessions. Materials covered physiological changes during pregnancy, nutrition, reproductive hygiene, danger signs, childbirth preparation, and postpartum care. Results showed a knowledge score increase of 42.5% (from 58.3±12.4 to 83.1±8.7) with significance p<0.001. Participation reached 86.7% with satisfaction level of 4.3/5.0. The program proved effective in improving reproductive health knowledge and can be replicated in other primary health centers with local context adaptation.

Dysmenorrhea is one of the most common reproductive health problems among women of reproductive age and can interfere with daily activities and productivity, while limited knowledge regarding proper management often leads to ineffective handling of menstrual pain.

The activity employed a pre-experimental design with a one-group pretest–posttest approach involving women of reproductive age visiting PMB Lina Contesa. Health education was delivered through counseling and interactive discussions using leaflet media. Knowledge levels were measured before and after the intervention using a structured questionnaire and analyzed descriptively and comparatively. The results showed an increase in participants’ knowledge after the educational intervention, with most respondents shifting from low to moderate knowledge levels before education to good knowledge levels after education. These findings indicate that health education on dysmenorrhea management is effective in improving women’s understanding, highlighting the importance of continuous educational programs in midwifery care settings as a promotive and preventive strategy for women’s reproductive health

Mathematics is a core subject that develops critical thinking skills; however, many third to fifth-grade elementary school students face difficulties with conventional teaching methods that tend to be uniform and less adaptive. This study aims to develop and implement a mobile-based educational game, "Ethno Run," which integrates the Bayesian Knowledge Tracing (BKT) algorithm to provide an adaptive learning experience. The method used is Research and Development (R&D) with the Multimedia Development Life Cycle (MDLC) framework. The system uses BKT to track students' mastery in real-time by analyzing their responses to pre-tests and exercises within the game, which then adjusts the difficulty level and focuses the post-test on areas identified as weak, such as arithmetic operations and geometry. The findings show that this adaptive approach significantly improves learning outcomes, with the average score increasing from 44.33 on the pre-test to 85.33 on the post-test among 30 students. This study concludes that the integration of Artificial Intelligence through BKT effectively personalizes learning, enhances student motivation, and provides data-driven insights for teachers regarding students' progress. The implication of this research is that adaptive game-based learning serves as a feasible interactive solution to bridge the gap in conventional basic mathematics education.

This article investigates the effectiveness of cooperative learning using vocabulary flashcards in improving students’ mastery of English adjectives. The research was conducted due to students’ limited vocabulary knowledge. The objective of this article was to examine whether the implementation of a cooperative learning model supported by vocabulary flashcards could enhance students’ adjective mastery and learning engagement. A pre-experimental research design with a one-group pretest–posttest approach was employed. The participants consisted of 15 junior high school students enrolled in an English course. Data were collected through pretest, posttest, classroom observation, and a student response questionnaire. Quantitative data were analyzed using descriptive statistics and N-Gain analysis, while qualitative data were obtained from observation sheets and questionnaire responses. The findings indicate a noticeable improvement in students’ posttest scores compared to their pretest results, with the mean N-Gain score categorized as moderately effective. In addition, observation data revealed high levels of student participation during cooperative learning activities. Questionnaire results further showed positive student responses toward the use of cooperative learning and vocabulary flashcards, particularly in terms of motivation, confidence, and ease of understanding English adjectives. These findings suggest that cooperative learning combined with vocabulary flashcards can effectively support students’ vocabulary development and active engagement. In conclusion, the study provides empirical evidence that cooperative learning facilitates meaningful interaction and knowledge construction, supporting its implementation in English vocabulary instruction. However, future research is recommended to involve larger samples and comparative research designs to strengthen the generalizability of the findings.
