Abstract

This study explores and investigates the process of students’ mathematical thinking literacy in solving mathematical problems. This qualitative descriptive research used a test sheet consisting of one item adapted from the PISA mathematical problem model and interview guidelines, as the instrument.  One male and two female participants were selected based on problem-solving characteristics. After that, task-based interviews were carried out to investigate the process of students’ mathematical thinking literacy. Data analysis was initiated by reviewing, reducing, and concluding all collected data to describe students’ mathematical thinking literacy in solving mathematical problems. The findings suggest that mathematical thinking literacy is initiated by understanding the problem (understanding), presenting the problem in a simpler form (specializing) to represent ideas, and creating patterns or relationships (generalizing).  Based on the relationship between the problem, the subject predicts a solution (conjecturing) or determines the solution to the problem, re-checks (justifying) the problem-solving process to find a logical final result, and communicates the reasons (convincing) to convince the truth of the results obtained. The results of this study help teachers understand the process of students’ mathematical thinking literacy in solving mathematical problems so that it can be used to determine the appropriate strategy in the learning process to improve students' mathematical problem-solving abilities

Abstract

Maize and mungbean are two common crops grown in dryland areas with sandy soil structures. This study aimed to explore the potential of adding cayenne pepper to increase crop diversity using strip intercropping (SI) as a potential system to improve farmers' return. There were seven treatments tested: monoculture maize, monoculture mungbean, monoculture cayenne pepper, SI maize and mungbean, SI maize and cayenne pepper, SI mungbean and cayenne pepper, and SI maize, mungbean, and cayenne pepper. The size of the treatment plot was 700 cm × 500 cm, and all the treatments were arranged in a Randomized Block Design with three replications. The study showed no difference in the land equivalent ratio (LER) for all the SI treatments, with a value of around 1.0. This indicates no advantage of SI over monocropping in terms of land usage. However, when the market prices valued the yield of each component crop in SI at harvest, the highest economic value came from monocrop cayenne pepper treatment (IDR 246 million ha-1). All the SI treatments involving cayenne pepper resulted in a higher return than the monoculture of maize or mungbean. The lowest economic value was shown by monoculture mungbean treatment (IDR 33.1 million ha-1). These results indicate that diversifying crops can improve farmers' return, especially by incorporating cayenne pepper in dryland with sandy soil.

Abstract

In this paper, the results of the characterization of a Fiber Bragg Grating (FBG) Accelerometer for detecting vibrations underwater are reported. The FBG Accelerometer, consisting of three FBGs, is utilized to detect underwater vibrations in three-dimensional directions. A water pump, with positions varied from 0 to 10 cm, is employed as the vibration source. Furthermore, the experimental results are presented in the form of the peak wavelength shift reflected by the FBG (ΔλB) and frequency. From the experiment results, it is shown that with increasing distance, ΔλB decreases linearly with successive gradients of 0.0058 nm/cm; 0.0059 nm/cm; and 0.0045 nm/cm. for FBG X, Y, and Z. It is also shown that with increasing distance, there is a decrease in frequency from 50 Hz for FBGs X, Y, and Z to 39 Hz; 38 Hz; and 40 Hz for FBGs X, Y, and Z respectively.

Abstract

Sudden death, particularly among seemingly healthy individuals, presents a critical challenge in both medical and athletic communities. This literature review investigates sudden cardiac death (SCD) in adolescent athletes, emphasizing the role of genetic screening. Utilizing various studies from 2019 to 2024, the review highlights that SCD, while rare, often stems from cardiovascular issues such as cardiomyopathy and coronary artery anomalies. Pre-participation screening, including ECGs, is crucial in identifying at-risk individuals, yet raises ethical debates regarding athlete disqualification. Genetic factors play a significant role, with inherited heart conditions frequently implicated in SCD cases. Comprehensive genetic screening and family evaluations are vital, although widespread implementation is hindered by limited positive outcomes and potential psychosocial effects. Epidemiological studies reveal a higher incidence of SCD during competitive sports, underscoring the need for tailored prevention strategies. Findings emphasize the importance of multidisciplinary collaboration in enhancing screening methods, risk assessment, and preventive interventions to mitigate sudden mortality in young athletes. The study concludes that lifestyle modifications, promoted by health organizations, and advancements in genetic diagnosis are essential in improving the health and safety of athletes. Efforts to integrate cardiovascular and genetic screening into clinical and athletic practice are paramount, aiming to reduce the incidence of SCD and enhance the well-being of young athletes globally.

Abstract

This literature review delves into the impact of regular physical activity on lipid profiles and cardiovascular health in adolescents, addressing the growing concern of sedentary lifestyles and unhealthy habits contributing to increased cardiovascular disease risks among teenagers. By systematically searching academic databases and scientific journals using relevant keywords, a selection of 8 articles was chosen for review after rigorous screening and eligibility assessment. The findings of the review underscore the significant relationship between physical activity, metabolic parameters, and cardiovascular risk factors in adolescents. Studies consistently highlight the benefits of regular physical activity in improving lipid profiles, insulin sensitivity, and overall cardiovascular parameters in this population. For instance, adolescents engaging in moderate to high-intensity physical activity demonstrated reduced risks of metabolic syndrome and improved insulin sensitivity. Lifestyle modifications encompassing increased physical activity and dietary changes were associated with positive alterations in lipid and glycemic profiles, particularly in high-risk pediatric individuals. Notably, regular vigorous-intensity physical activity was found to yield favorable cardiometabolic outcomes in adolescents with type 2 diabetes. In conclusion, the review emphasizes the critical role of regular physical activity in maintaining cardiovascular health and managing metabolic risk factors among adolescents. Participation in physical activity, particularly at moderate to high intensity, holds promise for significant improvements in lipid profiles and cardiovascular parameters. These findings underscore the importance of promoting active lifestyles among teenagers to prevent cardiovascular disease and enhance overall health outcomes.
