Left ventricular hypertrophy (LVH) can be identified through both electrocardiography (ECG) and echocardiography, with echocardiography recognized as the gold standard for the assessment of LVH. This imaging modality determines the presence of LVH by evaluating the left ventricular mass index (LVMI). For diagnostic purposes, LVH is defined in males as a left ventricular mass index greater than 115 g/m² and in females as greater than 95 g/m². Despite the high accuracy of echocardiography in diagnosing LVH, access to this examination is not universal across all healthcare facilities. Consequently, electrocardiography, a widely available, non-invasive, and cost-effective diagnostic tool, serves as an alternative for the diagnosis of LVH. Several criteria exist for the electrocardiographic assessment of LVH, including the Sokolow-Lyon and Cornell voltage criteria. However, the sensitivity of these electrocardiographic methods remains relatively low, with reported sensitivities of 17% for the Sokolow-Lyon criteria and 35% for the Cornell criteria. In left ventricular hypertrophy, the interstitium experiences changes characterized by fibrosis and other deposits. These alterations can reduce the expression of hypertrophic myocardial tension and limit the diagnostic capabilities of surface electrocardiograms. Additionally, several factors influence electrical tension, including variations in chest wall thickness, heart muscle activity, the distance of the electrode from the left ventricle, and lung activity. The presence of these limiting factors can increase the rate of false negatives in diagnosis. In 2017, Peguero and Lo Presti introduced novel criteria for the diagnosis of LVH, defined by evaluating the deepest S wave and summing it with the S wave in lead V4. According to these new criteria, LVH is identified as ≥ 2.8 mV in men and ≥ 2.3 mV in women. The Peguero-Lo Presti criteria demonstrate improved sensitivity when compared to traditional criteria such as Sokolow-Lyon and Cornell, offering enhanced diagnostic accuracy.

The surgery often causes anxiety, which has an impact on physical and psychological conditions of preoperative patients. The data from WHO shows that 50% patients all over the world experienced anxiety, where 5-25% patients are between 5 and 20 years old, and 50% patients are 55 years old. Pre-operational anxiety reaches 534 million patients. Many factors affect anxiety in patients, including family support. This study aims to acknowledge the correlation between family support and anxiety of post-surgery patients in Meuraxa Regional General Hospital, Banda Aceh. This study employs an analytical correlational method with a cross-sectional approach by involving 51 patients selected using an accidental sampling technique. A family support questionnaire is adopted from Nurwulan, with a Cronbach's alpha 0.856. The questionnaire of anxiety using the APAIS scale of Cronbach's alpha 0.825. Univariate and bivariate analysis using the chi-square test. The results indicate that among 51 respondents, the level of anxiety is in a medium state, as 26 respondents (51.0%), family support is in the high category, 47 respondents (92.2%), with a P-value 0.026 (P-value < 0.05). In conclusion, there is a significant relationship between family support and preoperative anxiety at Meuraxa General Hospital Banda Aceh. Families are expected to continuously provide emotional, informational, instrumental, and appraisal support so that patients feel calmer, are able to reduce excessive anxiety, and are better prepared to undergo surgery.

Total cholesterol measurement is essential for assessing cardiovascular risk, but consistency between laboratory instruments must be validated for reliable results. Architect C4000 and Alinity C1000 operate on enzymatic principles but differ in system design, reagents, and supporting technology. This study aimed to compare total cholesterol measurements between the two instruments using a non-parametric statistical approach (Mann-Whitney test). A comparative analytical design was conducted with 100 serum samples obtained via purposive sampling and divided for measurement with each device. Statistical analysis evaluated differences, and mean differences were calculated using the Hodges-Lehman method. Results showed mean cholesterol values of 182.98 mg/dL for Architect and 182.37 mg/dL for Alinity, with no significant difference (p=0.9942) and a median difference of 0.0 (95% CI: -9.0 to 9.0). Data distribution was nearly identical for both instruments in terms of mean and spread. Therefore, both methods demonstrate comparable validity in total cholesterol measurement, as they rely on similar principles and technologies, with reagents calibrated to the same standards.

This study aims to apply a simple experimental approach titled “Balloon Expands Without Being Blown” to enhance fifth-grade students’ understanding of gas concepts in science learning at MI Malik Ibrahim. The study originates from the observation that students often struggle to grasp the concepts of gases and acid–base reactions, which are typically taught in a purely theoretical manner without engaging hands-on experiences. The research employed a Classroom Action Research (CAR) design following Kurt Lewin’s model, which includes four interconnected stages: planning, acting, observing, and reflecting. The participants consisted of 22 fifth-grade students from MI Malik Ibrahim. The findings reveal a substantial improvement in both learning achievement and classroom participation after the experimental activity was introduced. Students’ average scores increased from 62 to 85, with 82% showing measurable progress. Furthermore, inquiry and discussion activities became more frequent, and most students could correctly explain the formation of carbon dioxide (CO₂) gas. Overall, the results suggest that the balloon expands without being blown experiment effectively fosters scientific conceptual understanding, promotes active engagement, and stimulates motivation toward learning science.

The assessment of student achievement is one of the main indicators in measuring the effectiveness of the educational process in Islamic boarding schools. The assessment process that has been carried out manually tends to be subjective, so it has the potential to cause a discrepancy between the student's achievement and the results of the evaluation received. This research aims to develop a decision support system that is able to assess student achievement in an objective, measurable, and transparent manner by applying the PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) method. This method is used because it has the ability to manage various assessment criteria simultaneously to produce fair and rational alternative rankings. The research approach used is quantitative descriptive by involving a number of students as research samples. The data was analyzed through the stages of determining weight, calculating preference values, and determining the values of leaving flow, entering flow, and net flow as the basis for determining the final ranking. The results of the study show that the PROMETHEE method can provide consistent and accurate ranking results, by placing students who have academic excellence, discipline, and positive personalities in the top position. These findings prove that the PROMETHEE method is effective in overcoming the subjectivity of the assessment and increasing the transparency of the evaluation process. Practically, the resulting system can help the pesantren in determining outstanding students more efficiently and based on data, as well as theoretically strengthen the application of multicriteria decision-making methods in the context of Islamic education.’

The formation of Islamic character and environmental awareness is an integral part of the national education goals which are oriented towards developing the personality of students as a whole. In rural schools, such as the free school in Karang Anyar Village, limited learning facilities often become a challenge in implementing character education based on Islamic and environmental values. This study aims to analyze efforts to strengthen Islamic character and environmental awareness through the use of school libraries and family medicinal plant (TOGA) planting activities as contextual learning tools. The research used a descriptive qualitative approach with data collection techniques through observation, interviews, and documentation during the real work lecture (KKN) program. Data analysis is carried out through a process of reduction, presentation, and drawing conclusions in order to obtain an in-depth picture of the effectiveness of the activity. The results of the study show that literacy activities in the library are able to increase reading interest, Islamic insight, and the habituation of religious attitudes among students. Meanwhile, TOGA activities contribute to the formation of attitudes of responsibility, mutual cooperation, and concern for the school environment. The synergy between these two activities has proven effective in strengthening Islamic character values ​​and environmental awareness, as well as creating a school culture that is religious, productive, and ecologically aware.
