This study aims to analyze students’ mathematical reasoning abilities in quadratic function material through the use of Desmos. The research employed a qualitative descriptive approach using a case study and usability testing method. Data were collected through post-tests and interviews involving students’ responses in solving quadratic function problems. The analysis focused on several indicators of mathematical reasoning, including procedural skills, conceptual understanding, and analytical ability. The results show that students generally demonstrate adequate procedural reasoning, particularly in substitution and computation tasks. They are also able to relate algebraic representations to geometric interpretations, such as determining intercept points and analyzing the direction of parabolas. However, limitations were found in conceptual understanding, especially in identifying graph characteristics without relying on procedural steps. The use of Desmos significantly supports the development of students’ mathematical reasoning by providing real-time visualization, facilitating exploration of function parameters, and enabling verification of results. Overall, Desmos contributes to enhancing procedural, conceptual, and analytical dimensions of mathematical reasoning, although its effectiveness depends on proper instructional design.

Differential equations involve derivatives of unknown functions and are widely used in mathematical modeling of various real-world problems. They can be classified based on linearity, homogeneity, coefficients, number of independent variables, degree, and order, thus requiring appropriate solution methods. One commonly used approach is the reduction of order method, which simplifies equations by reducing their order step by step. However, this method generally requires the solution of the corresponding homogeneous equation as an initial step. This study aims to solve nonhomogeneous linear ordinary differential equations of order with constant coefficients using the reduction of order method without determining the homogeneous solution. This research is a theoretical study based on relevant references concerning solution methods and types of differential equations. The procedure consists of two main stages: determining the fundamental symmetric polynomial variables based on the coefficients and constructing a sequence of solutions through first-order linear differential equations obtained from the reduction process. The results show that this method systematically produces the general solution of linear differential equations of order , making it an effective and efficient alternative approach

This research is driven by the significance of examining language meaning, particularly connotative meaning which is often used to convey implicit messages in literary works. Folktales, as one type of oral literature, often utilize character names that carry specific meanings, such as Malin Kundang from Minangkabau. The aim of this research is to uncover the connotative meaning of the character name “Malin Kundang”, as well as its relationship with the moral and cultural values of the society. The methodology involves qualitative research using semantic analysis and a descriptive approach. Data were collected from the Malin Kundang folktale text thru library study and documentation techniques. Next, the processes of identification, classification, and interpretation of meaning were done in order to examine the data. The research result show that denotatively, the name Malin Kundang only functions as the identity of the character, but connotatively, it functions as a symbol of a disobedient child who does not respect their parents. The meaning is formed from the plot of the story and reinforced by the Minangkabau cultural values that uphold respect for parents. The implications of this research indicate that the naming of characters in folklore is not only linguistic but also reflects the moral and cultural values inherited by society.

Method: The development method employed the Rapid Application Development (RAD) approach using MATLAB programming language. The GUI is designed to load transverse and sagittal USG images, display automatic segmentation results, and calculate thyroid gland volume based on dimensions measured automatically from the segmentation output. Testing was conducted using USG image data from 15 volunteers, and GUI functionality was evaluated using black box testing. Result: The GUI successfully displayed USG images and segmentation results with a responsive 4-panel interface; zoom, pan, and image navigation features functioned well. Automatic segmentation occurred in real-time after image input, and volume measurement results appeared automatically. Black box testing evaluation showed all GUI features operated as expected. The average Dice Similarity Coefficient (DSC) of 0.91 indicates high performance of the U-Net model in thyroid segmentation, consistent with previous findings. Statistical testing confirmed no significant difference between volume measurements using the application and manual methods (p = 0.953). Conclusion: This GUI implementation facilitates users in performing deep learning-based segmentation and visualization of thyroid USG images, improving efficiency and accuracy in thyroid volume measurement. The GUI has potential applications in clinical practice and radiology education.

Preeclampsia remains a major contributor to maternal morbidity and mortality, particularly in developing countries such as Indonesia. Early detection and integrated management at the primary healthcare level are essential to prevent disease progression and improve maternal outcomes.  Modifiable risk factors such as maternal obesity, inadequate calcium intake, and poor clinical management contribute significantly to disease progression (WHO, 2021; Zhang et al., 2020). This study aimed to evaluate the effectiveness of an Integrated Maternal Health Model (IMHM) combining risk assessment, nutritional intervention, and clinical management for early prevention and control of preeclampsia in primary healthcare settings. A quasi-experimental cohort study was conducted among 104 pregnant women, consisting of 52 preeclamptic and 52 normotensive participants in community health centers in Medan, Indonesia. Data were collected across four antenatal visits, including blood pressure measurements, proteinuria (dipstick), calcium intake, supplementation adherence, and antihypertensive therapy. Statistical analyses included bivariate and longitudinal tests. The results showed that maternal obesity, history of preeclampsia, and hypertension were significant risk factors. Adequate calcium intake demonstrated a protective effect against preeclampsia (p < 0.05), consistent with recent evidence indicating that calcium supplementation can reduce the risk of preeclampsia by up to 49%. However, calcium supplementation did not significantly influence blood pressure among normotensive pregnant women. Antihypertensive therapy, particularly intensive nifedipine regimens, showed significant differences in blood pressure patterns across visits (p < 0.05). In addition, proteinuria levels significantly decreased over time (p < 0.001), indicating improvement in renal function. In conclusion, the IMHM is effective in improving maternal outcomes through a multi-component approach integrating clinical, nutritional, and monitoring strategies. This model provides a practical and scalable framework for early prevention and management of preeclampsia in primary healthcare settings.

Digital transformation has brought fundamental changes to the structure and dynamics of modern industrial economics. Technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and big data not only modify production and distribution processes but also revolutionize marketing strategies and patterns of industrial competition. This study is motivated by the need to understand how digital marketing transformation influences the development of competitive advantage through changes in digital market structure from an industrial economics perspective. In this context, digital marketing functions as a strategic instrument that integrates technology, data, and consumer behavior into market mechanisms. The analysis shows that digitalization creates a network-based market structure characterized by the concentration of economic power in major digital platforms and dominance in data control. This structure affects the intensity of competition, the direction of innovation, and patterns of industry differentiation. Digital marketing transformation enhances efficiency, expands market access, and lowers entry barriers for new players, yet it also creates competitive imbalances due to the dominance of large platforms.Through a digital Structure–Conduct–Performance (SCP) approach, the study finds that market structure acts as an intermediary variable that channels the impact of digitalization on competitive advantage. Digitalization significantly promotes industrial efficiency, innovation, and profitability. Proposed strategic solutions include strengthening digital literacy, developing adaptive regulations, and fostering cross-sector collaboration to create an inclusive, competitive, and sustainable digital industrial ecosystem

Industrial dust exposure is a hazardous work environment that can potentially cause respiratory problems in workers, particularly in industrial sectors with production activities that generate high levels of dust particles. This study aims to examine the relationship between industrial dust exposure and respiratory problems in workers through a systematic review. The method used was a qualitative descriptive literature study of scientific articles from 2021-2026 obtained through Google Scholar based on inclusion and exclusion criteria, then systematically analyzed. The results of the study indicate that most studies found a significant relationship between dust exposure and respiratory problems, especially in work environments with dust levels exceeding the threshold limit (TLV). Common symptoms include coughing, shortness of breath, phlegm production, and decreased lung function. In addition to dust levels, other factors such as duration of exposure, length of service, smoking habits, and the use of personal protective equipment (PPE) also play a role in increasing the risk. However, several studies showed insignificant results, which are suspected to be influenced by the use of proper PPE and an effective work environment control system. These findings confirm that dust exposure is a significant, multifactorial risk factor, necessitating comprehensive control efforts through a hierarchy of controls, environmental monitoring, and regular health checks to prevent long-term impacts on worker health.

Providing passive ROM to the extremities can help improve blood circulation, improve respiratory function, and support the recovery of consciousness as assessed using the Aldrete Score. The purpose of this study was to determine the effect of providing early passive ROM mobilization of the extremities on changes in the Aldrete score in patients after general anesthesia. This study used a pre-experimental design with a one-group pretest-posttest approach. The study sample consisted of 57 respondents. The intervention provided was early passive ROM mobilization. The Aldrete score was measured before and after the intervention. Data analysis used the Wilcoxon signed rank test with a significance level of α = 0.05. The results showed that the average Aldrete score before the intervention was 5.89 and after the intervention increased to 9.26. The results of the statistical test showed a p value = 0.0001 (p <0.05), which means that there is a significant effect of providing early passive ROM mobilization of the extremities on increasing the Aldrete score after general anesthesia. From this study, it can be concluded that there is an effect of providing early passive ROM mobilization of the extremities on increasing the Aldrete score after general anesthesia.

Stroke often causes hemiparesis, which impairs hand motor skills and independence in daily activities. Mirror therapy is a rehabilitation intervention that stimulates motor function through visual feedback, while patient motivation plays a crucial role in exercise adherence. This study aims to analyze the effect of mirror therapy and patient motivation on hand motor skills in patients with hemiparesis.The study used a quasi-experimental design with a pretest–posttest approach in 30 hemiparesis patients undergoing rehabilitation at the Ciherang Community Health Center. Mirror therapy intervention was administered for 20–30 minutes, three times per week for four weeks. Hand motor skills were measured using Manual Muscle Testing on a scale of 0–5, while patient motivation was assessed using a questionnaire.The results showed a significant increase in hand motor skills after mirror therapy (p < 0.05) and higher patient motivation was associated with greater motor score improvement (p < 0.05). Mirror therapy and patient motivation have been shown to have a positive effect on hand motor skills in hemiparesis patients, so this combined intervention can be considered as part of a stroke rehabilitation program.

This study analyzes the function of deixis in building emotional relationships between characters in the short film "Seutas Kenangan" using a sociopragmatic approach. Besides being a medium for communication, language also functions as a medium for expressing distance, closeness, and social relationships that impact the emotional relationships that occur. Therefore, this study aims to examine how various types of deixis play a role in building emotional relationships between characters. The method used in this study is descriptive qualitative with data in the form of dialogues obtained through listening and note-taking techniques. This analysis was conducted by identifying the types of deixis, analyzing sociopragmatic aspects, and then interpreting the emotional relationships created. Based on the results of the study, there are deixis of person, time, place, social, and discourse that are related in representing emotional relationships. The emotional relationships found in this analysis include affection, longing, inner conflict, avoidance, and emotional stress due to prevailing social norms. The relationship between the function of deixis and the sociopragmatic approach shows that the function of deixis is not merely a referent indicator, but can also be a strategy for representing emotional relationships influenced by social and cultural conditions.

Environmental damage caused by human activities has become an increasingly pressing global issue. Poetry as a literary work has the power to represent ecological problems symbolically and critically. This study aims to describe the representation of the impact of the environmental crisis in Taufiq Ismail's poems, namely "Menengajah Ke Atas, Merenungi Ozone yang Tak terlihat" and "Membaca Tanda-Tanda." The analysis is based on Greg Garrard's ecocritical study. This study uses a qualitative method with content analysis techniques. There are two stages of analysis, namely the literal and symbolic meaning of the poems, then an ecocritical interpretation is carried out based on Garrard's categories which include pollution, wilderness, apocalypse, dwelling, animals, and earth. The results of the study indicate that both poems represent the impact of the environmental crisis through health problems due to pollution and radiation, damage to water and forest ecosystems, climate change, threats to human living space, and the decline in biodiversity. The research findings also show that the most dominant categories are pollution and apocalypse, which confirms that the environmental crisis in Taufiq Ismail's poems is the result of human behavior that ignores nature. Thus, Taufiq Ismail's poems not only function as aesthetic works, but also as cultural criticism and moral warnings for humanity.

Low-rank coal generally has a high moisture content, which results in a low calorific value and suboptimal quality for utilization as an energy source. One method that can be applied to improve coal quality is the Upgrading Brown Coal (UBC) process, which functions to reduce moisture content and increase fixed carbon value. This study aims to analyze the effect of heating time and the ratio of used oil composition on improving coal quality based on proximate parameters. The research method includes collecting coal samples from four locations in Samarinda and its surrounding areas, namely SMAN 1 Samarinda, Bhineka Street, Palaran Stadium, and Tani Bakti Village. The samples were analyzed using proximate analysis, including inherent moisture (IM), ash content (AC), volatile matter (VM), and fixed carbon (FC), both before and after the UBC process. The upgrading process was carried out with variations in heating time and used oil composition as a coating medium to enhance coal stability and prevent moisture reabsorption. The final results of the upgrading process showed the best values of inherent moisture at 13.64%, ash content at 4.66%, volatile matter at 55.06%, and fixed carbon at 44.94%. The results indicate that the UBC process is capable of reducing inherent moisture and increasing fixed carbon, thereby improving coal quality. Variations in heating time and used oil composition have a significant effect on changes in proximate parameters. Longer heating time and an appropriate ratio of used oil composition result in a more optimal improvement in coal quality.

The University of North Sumatra Mini Stadium is a sports complex covering an area of 6.4 hectares. This facility is located on Jalan Almamater, Padang Bulan, Medan Baru, Medan City, North Sumatra. Various sports activities are facilitated in this area, including volleyball, basketball, tennis, table tennis, taekwondo, rock climbing, archery, and soccer, all of which are integral parts of the facilities and infrastructure available at the Mini Stadium. In addition to the main stadium, the University of North Sumatra Mini Stadium complex is equipped with various supporting buildings and fields. These facilities serve as a means for developing and channeling students’ interests and athletic talents, as well as a public space that can be utilized by the people of Medan City for sports activities. However, functionally, the University of North Sumatra Mini Stadium complex is considered suboptimal in effectively accommodating and supporting sports activities. The non-compliance of installations with applicable standards, as well as the condition of a number of facilities that no longer meet suitability criteria and tend to be neglected particularly the soccer field and its supporting facilities are the main problems at the University of North Sumatra Mini Stadium complex. Therefore, the redesign of the University of North Sumatra’s mini stadium, using a structural architecture approach as an aesthetic element, is expected to result in a building that is not only structurally sound but also aesthetically pleasing.

This study aims to analyze the factors that influence the residential spatial system of the Marori and Mengge ethnic groups in Wasur Village, Merauke, South Papua, in the context of their involvement in the eucalyptus oil industry as a leading tourism product of Wasur National Park. A rationalistic qualitative approach is used with the main theory of behavioral setting to examine the relationship between behavior, local culture, and spatial structure. The results of the study indicate that houses not only function as domestic spaces, but also as places for the production of eucalyptus oil, especially at the packaging stage. The overlapping use of space causes space invasion, changes in function, and the emergence of high spatial flexibility. The space of the house undergoes a temporal functional transformation, adjusting to the intensity of economic activities and cultural rituals of the community. Private, semi-public, and spiritual spaces experience shifting boundaries, which have an impact on social relationship patterns and living comfort. This study also found that social structure, customary values (Boan/marga), and division of customary areas play an important role in the formation of the spatial system. These findings are expected to be an important contribution to the development of residential architecture based on behavior and local wisdom, as well as community-based conservation area management. This study also highlights the urgency of preserving the culture and existence of indigenous tribes amidst the current of modernization and the threat of extinction.

This article discusses ethical values in the philosophy of Islamic education as a response to contemporary challenges, such as moral crisis, declining character, and identity confusion. This study uses a literature review method with a philosophical and normative approach, based on Islamic teachings and the thoughts of educational figures. The results show that the philosophy of Islamic education contains important values such as monotheism, justice, responsibility, honesty, and good morals. These values are interconnected and play a significant role in shaping human personality. In addition to serving as a theoretical foundation, these values also function as guidelines in educational practice aimed at forming a complete human being (insan kamil). In the modern era, which is influenced by globalization and technological development, the application of Islamic ethical values is highly important to maintain a balance between intellectual intelligence and spiritual maturity. Therefore, the philosophy of Islamic education remains relevant as a solution for creating an education system that is not only intellectually advanced but also character-based and morally grounded. This study emphasizes that Islamic education needs to be directed toward the formation of moral awareness, the strengthening of spirituality, and the development of students’ social responsibility in daily life.
