However, levels of alpha-fetoprotein (AFP) did not show significant differences between preeclamptic and normotensive women.

Adapting to students’ learning styles is a key factor in enhancing the effectiveness of higher education, particularly in Informatics programs where learning preferences vary widely. This study aims to segment students based on their learning styles using the K-Means clustering algorithm, guided by the VARK model (Visual, Auditory, Read/Write, Kinesthetic). Data were collected from 130 Informatics students, including information on their learning preferences, and processed through normalization techniques. The optimal number of clusters was determined using the Elbow Method and Silhouette Score, and subsequent cluster interpretation was conducted. The results identified three dominant clusters, each representing distinct learning behavior patterns. These clusters were analyzed to recommend tailored instructional strategies for each group. Specifically, Visual learners were found to benefit from graphic-heavy materials, Auditory learners preferred lectures and discussions, Read/Write learners thrived on written content and detailed notes, while Kinesthetic learners responded best to hands-on activities. The findings support the development of adaptive, data-driven teaching approaches that align with the actual learning tendencies of students in Informatics. Moreover, the study demonstrates that the K-Means method is effective in systematically identifying student learning profiles, which can be used to inform instructional improvements. This personalized approach to teaching could significantly enhance learning outcomes by providing students with the most effective educational experiences tailored to their individual learning styles

The increase in traffic volume in urban areas often triggers various problems, especially at Road intersection points that have a high level of interaction between vehicles. One of the locations that experience these problems is the intersection with the island of traffic without signal on Jl. Tebu-Jl. Tabrani Ahmad, City Of Pontianak. This study aims to analyze the performance of the intersection in the existing condition and project its performance in the next five years (2030), as well as formulate alternative treatment that can improve the smoothness of traffic. The analysis method refers to Indonesian road capacity guidelines (PKJI) 2023 and modeling using software PTV VISSIM. The data collected include intersection geometry, traffic volume, and vehicle speed. Traffic volumes were obtained through CCTV recordings for three consecutive days, then processed and presented in the form of tables and graphs for easy interpretation. The results of the existing condition analysis showed that the degree of saturation (DS) reached 0.407 with an average delay of 9.539 seconds (Level of Service/LOS B) based on PKJI, while VISSIM simulation resulted in a delay of 12.54 seconds (LOS B). The five-year projection (2030) shows an increase in DS to 0.878 with a delay of 15.177 seconds (LOS C) from PKJI, and 23.35 seconds (LOS C) from VISSIM, which indicates a decrease in Junction performance as traffic grows. Two handling alternatives were analyzed, namely the construction of roundabouts and the implementation of traffic flow management. VISSIM simulation shows that the roundabout can reduce the delay to 14.31 seconds with a queue length of 20.34 m (LOS B), while the flow management produces a delay of 11.81 seconds with a queue of 13.14 m (LOS B). This result confirms that both alternatives are able to improve the performance of the intersection compared to the projected condition without handling, so that it can be a technical recommendation for urban traffic planning in Pontianak.

Weather and cloud cover are two fundamental atmospheric elements that are closely interconnected and play a vital role in understanding, classifying, and predicting atmospheric conditions. Accurate classification of weather conditions is essential not only for meteorological studies but also for practical applications in agriculture, aviation, transportation, and disaster management. Among the various statistical techniques available, correspondence analysis has proven to be an effective exploratory method for revealing associations among categorical variables by displaying their relationships in a two-dimensional graphical map. The primary objective of this study is to examine the relationship between different categories of weather conditions and levels of cloud cover using correspondence analysis. The data were sourced from the Kaggle platform, consisting of 13,200 observations with two key categorical variables: weather conditions (sunny, cloudy, rainy, and snowy) and cloud cover (clear, partly cloudy, cloudy, and overcast). This large dataset provides sufficient variability and reliability to capture the complex interdependence between the two variables. The findings reveal a statistically significant relationship between weather categories and cloud cover levels. The correspondence map visualization shows distinct patterns: clear weather is strongly associated with cloudless skies, while rainy and snowy weather conditions are predominantly linked to fully overcast skies. Cloudy and partly cloudy conditions occupy an intermediate position on the correspondence map, reflecting a transitional state between favorable and unfavorable weather. The first dimension of the map represents a spectrum from favorable weather conditions (sunny and clear) to adverse conditions (rainy and snowy), whereas the second dimension primarily reflects the intensity or density of cloud cover, ranging from thin to thick cloud layers. Overall, this study demonstrates the usefulness of correspondence analysis as an exploratory tool for meteorological data, offering valuable insights into the interrelation of weather and cloud cover categories.

The production process of graphite glass at ABC faces challenges in the form of waste that has an impact on low operational efficiency. Waste in production activities can affect the quality, cost, and timeliness of product completion. This study aims to identify the most dominant types of waste and provide relevant improvement recommendations to improve production efficiency. The method used is Value Stream Mapping (VSM), a visual approach that maps the flow of the production process from raw materials to final products. The research stage is carried out through direct observation on the production floor, time study, interviews with employees, and documentation of production activities. The results of the analysis show that the most dominant form of waste is overprocessing, which is a repetitive activity that does not add value to the product. This causes longer production cycle times and reduces the effectiveness of resource use. To overcome this, this study provides several recommendations, including: combining production processes that have similar functions, redesigning workflows to make them more concise, and eliminating activities that do not provide added value. The implementation of this improvement has proven to be effective by increasing the Process Cycle Efficiency (PCE) value from 45% to 67%. The increase in PCE reflects that the production process has become more efficient, the workflow is smoother, and the rate of waste has decreased significantly. In addition, the results of this study also confirm that the application of the VSM method can be a strategic solution in identifying sources of inefficiency, designing continuous improvements, and increasing the competitiveness of companies. Thus, the company is expected to continue to evaluate, control, innovate, and improve technology so that efficiency achievements can be maintained, expanded, and improved consistently and sustainably in the future.

This article examines the crucial role of spatial communication, particularly through signage systems, in the effective implementation of functional zoning in academic libraries. Using a comparative case study method at the Bandung Institute of Technology (ITB) and Telkom University Libraries, this research analyzes how different visual communication strategies influence students' perceptions, behaviors, and sense of place formation.The findings indicate that the explicit and strategic visual communication approach at Telkom University successfully creates high spatial legibility and strengthens collective place identity. In contrast, the weak and ambiguous visual communication at the ITB Library causes users to rely more on personal habits, intuition, or previous experiences in accessing and utilizing the space. This not only hinders the formation of a coherent sense of place but also creates confusion that potentially degrades the quality of the user experience. The mismatch between spatial functions and user expectations leads to inefficiencies in facility utilization and disrupts user comfort within zones that should have clear functional boundaries, such as quiet zones, collaborative zones, and discussion zones. Furthermore, this article highlights the importance of integrating graphic design and architecture in creating a cohesive spatial experience. A consistently designed, informative, and aesthetically pleasing signage system not only enhances users' spatial orientation but also becomes a crucial element in shaping perceptions of the institution's character.

Traffic congestion in Jakarta has become a serious problem, affecting various aspects of life, such as time efficiency, environmental quality, and economic productivity. As one solution to overcome this problem, the Jakarta government is developing a mass public transportation system, including the Light Rail Transit (LRT). The LRT is expected to reduce congestion by providing a more efficient and environmentally friendly transportation alternative. In the process of planning and optimizing the LRT system, discrete mathematics, particularly graph theory, plays a very important role. Graph theory is used to model the LRT station network and track, with vertices representing stations and edges representing connecting lines between stations. With this model, various analyses can be performed to optimize the LRT line, such as finding the shortest path between two stations or evaluating the connectivity between existing stations. The use of graph theory allows the identification of more efficient routes, resulting in faster travel and reduced passenger waiting times. In addition, graph theory also plays a role in optimizing the LRT route by minimizing the number of transfers between stations or avoiding passenger congestion at certain stations. With proper route and network optimization, the LRT can make a significant contribution to reducing traffic congestion in Jakarta. Furthermore, the development of an efficient public transportation system also supports improved air quality and reduces reliance on private vehicles. Overall, the application of graph theory in LRT system planning is a strategic step towards creating more efficient and sustainable transportation in large cities like Jakarta. Beyond route optimization, graph theory is also very useful in analyzing route capacity and passenger distribution along the LRT system.

This quantitative study investigates the antecedents of Brand Loyalty in Genshin Impact players by examining the mediating role of Customer Value in the relationship between Experiential Marketing and Product Quality. Data were collected from 80 active players in Malang City using a purposive sampling technique and analyzed using a Partial Least Squares Structural Equation Modeling (PLS-SEM) approach to examine the relationship between variables. The results revealed two distinct pathways to loyalty formation. First, Experiential Marketing demonstrated a significant influence on Brand Loyalty, both directly and indirectly through strong mediation by Customer Value. This suggests that emotional, sensory, and relational experiences during gameplay play a crucial role in creating perceived value and long-term engagement. Second, although Product Quality demonstrated a significant direct influence on Brand Loyalty, its influence was not significantly mediated by Customer Value. This indicates that while the game's graphical quality, system performance, and technical stability are highly appreciated, they do not automatically translate into customer value without a meaningful experience. This study concludes that in the Games-as-a-Service model, loyalty is built through a dual strategy: a combination of superior product appeal and holistic value creation derived from a rich, curated player experience. Therefore, game developers need to synergistically integrate experience and quality strategies to build long-term brand loyalty. The practical implications of these findings are highly relevant for game developers and digital marketers. Marketing strategies are no longer sufficient to simply highlight technical features or product specifications; they must also address the emotional and social dimensions experienced by players.

In contemporary media, characters who self-diagnose with psychological disorders often reflect deeper emotional and psychological complexities rather than clinically accurate conditions. One compelling example is found in the British dark comedy-drama series The End of The F**ing World*, where James claims to be a psychopath. However, this self-diagnosis raises critical psychological questions: Is James truly incapable of empathy, or is his label a defense mechanism masking unresolved trauma from his childhood? By applying Sigmund Freud’s psychoanalytic theory—particularly the structural model of personality (id, ego, superego)—alongside Anna Freud’s theory of defense mechanisms, this study investigates the role of self-diagnosis not as an objective or medically valid truth, but as a psychological shield to avoid emotional vulnerability and confrontation with repressed pain. James' behaviors are analyzed through selected scenes and dialogues in the series, with additional triangulation from the original graphic novel to support the interpretation. The analysis reveals that James’ declaration of being a psychopath aligns more with mechanisms such as repression, projection, and emotional numbing, rather than the clinical criteria of psychopathy. His emotional detachment is revealed to be a constructed barrier stemming from maternal loss, neglect, and fear of connection. The study concludes that self-diagnosis in this context acts as a subconscious strategy to cope with unresolved trauma and to maintain psychological equilibrium amid inner conflict. This case exemplifies how fictional representations can mirror real-life struggles with identity, mental health, and the desire to label complex emotions through simplified diagnostic terms, especially in youth who lack proper support systems.
