Abstract

Investment is very popular nowadays to gain profits of the available property. Many investment portfolios are available but there are still a handful of users who have not been able to determine the best type of investment. Surely it would be very unfortunate if the property can not be well invested. Therefore, it is necessary to propose another alternative method that can determine the existing investment portfolio. This method begins by a process which details existing factors in every investment portfolio. Then, it takes intuition properly to give weight to the initial calculation. After that, it takes a Fuzzy concept as a tool to provide a numerical weight to each of the parameters. The final step is weighting process using Dempster Shafer method. With the use of three basic concepts, investors are expected to obtain objective and optimal computing results related to the profitable investment portfolio selection.

Abstract

Water is a vital resource and an essential human need for nearly all activities. Environmental Health Quality Standards for water encompass physical, biological, and chemical parameters, with a particular focus on Manganese (Mn) levels, which can be neurotoxic when consumed in excess. Filtration using a combination of Manganese Greensand and Coconut Shell Activated Carbon has been shown to effectively reduce Manganese levels in groundwater, achieving reductions of up to 80%. This study aims to evaluate the effectiveness of these media in lowering Manganese levels based on the volume of water filtered in RT 08, RW 01, Gunung Kebayoran Baru Subdistrict, South Jakarta. Utilizing a one-group pretest-posttest design, the study filtered groundwater with a Manganese concentration of 5 mg/L in volumes of 56, 112, 168, and 224 litres. The results indicated a decrease in Manganese levels, but the reductions did not meet the quality standards. The highest reduction percentage occurred at a volume of 56 litres, with a 48% decrease. Statistical analysis revealed a significant difference among the variations in water volume (p-value = 0.00001).  Keywords: Activated Carbon, Manganese Greensand, Environmental Health

Abstract

The availability of quality human resources determines the progress of a nation because by having quality human resources, a nation will be able to use and develop the latest technology to increase productivity on all fronts to realize the nation's prosperity. To achieve this, Indonesia is faced with an urgent problem to solve, namely stunting. The Indonesian government is aware of these problems and has taken several steps to solve them holistically by involving various approaches. However, there is no role model for religious institutions to accelerate the reduction of stunting prevalence in Indonesia. From this problem, the research design aims to build a model of the Islamic approach and environmental piety in increasing the convergence of accelerating stunting reduction in the community, as well as developing a model for accelerating stunting reduction through proper clean water and safe sanitation. The research design presented is expected to be material for joint discussion to contribute to improving the quality of human resources, Primarily by reducing the prevalence of stunting.

Abstract

Due to their extensive volume and range of features, seismic data is regarded as highly complex data. Earthquakes that typically composed of foreshocks, mainshocks, and aftershocks, exhibit a unique sensitivity to temporal dimension, a characteristic that differs them from other natural hazards. Foreshocks and aftershocks that emanate from a similar epicenter, often display temporal patterns that contribute significantly to determining a sequence. This study introduces a density cube-based approach to cluster spatiotemporal seismic data. It addresses spatial irregularities observed in earthquake clusters and incorporates temporal aspects, acknowledging that seismic events originating from a similar epicenter could occur in separate time frames. We achieved the highest Silhouette score of 0.935 in daily-based clustering and 0.782 in weekly-based clustering. Notably, our analysis reveals a trend where weekly clustering lambda λ tend to be lower (λ=0.01) than in daily clustering (λ=0.1, λ=0.5), thus emphasizing the significance of temporal granularity where daily clustering requires higher λ to capture rapid fluctuations, while weekly clustering benefits from lower λ to cover broader trends. These findings enhance the understanding of the nuanced interplay of temporal dynamics in seismic sequence analysis.

Abstract

Skeletal malocclusion, a common orthodontic condition, affects jaw function and dental health. It is often caused by genetic factors, abnormal growth, bad habits, or trauma. Conventional diagnostic models often fail to generalize across diverse datasets, leading to overfitting and poor test performance. This study aimed to improve diagnostic accuracy by incorporating Vision Attention mechanisms into a custom Convolutional Neural Network (CNN), enabling the model to focus on critical regions in X-ray images. A total of 491 radiographic images depicting facial skeletal structures with various malocclusion types (Classes 1, 2, and 3) were used in this study. A custom CNN was developed and evaluated both with and without attention mechanisms—specifically, Scaled Dot Product Attention and Multihead Attention—to assess their impact on classification performance. The baseline CNN without attention achieved an accuracy of 0.68. With Scaled Dot Product Attention, accuracy improved to 0.72, while Multihead Attention achieved the highest accuracy of 0.76. Evaluation using weighted average precision, recall, and F1-score showed that attention mechanisms significantly enhanced the model’s ability to differentiate between malocclusion classes. Notably, the Multihead Attention model yielded the best performance, reducing misclassification errors and improving generalization. Confusion matrix analysis revealed that it had the lowest classification errors, especially in distinguishing between Class 0 and Class 1. These results suggest that incorporating attention mechanisms, particularly Multihead Attention, enhances CNN performance by improving feature extraction and classification accuracy. Future research should explore more diverse datasets and implement advanced augmentation techniques to improve clinical reliability.

Abstract

An imbalance between workload and individual capacity may lead to work stress, which negatively impacts both employees’ health and company productivity. This study aims to analyze the relationship between workload and work stress among production workers at PT. X, Bekasi, West Java, in 2025. A quantitative method with an analytic cross-sectional design was applied. A total of 35 permanent production workers were selected using purposive sampling, and data were collected through questionnaires measuring workload indicators (metabolic rate and physical workload at the workplace) and work stress indicators (role ambiguity, role conflict, quantitative workload, qualitative workload, and career development). Data were analyzed using the Chi-Square test. The results showed that most workers experienced light workload, while work stress was mostly in the mild to moderate categories. The Chi-Square test produced a p-value of 0.014, indicating a significant relationship between workload and work stress. These findings highlight the importance of proper workload management, including task arrangement, job rotation, and career development strategies to reduce the risk of work stress and maintain productivity among production workers.
