This study aims to examine the application of a modified direct learning strategy combined with the demonstration method to improve students' cognitive abilities. The direct learning strategy is an approach that emphasizes the systematic and gradual delivery of material, so that students can understand concepts in a more structured manner. However, in practice, this strategy needs to be modified to be more engaging and appropriate to the characteristics of students. The demonstration method is used as a form of reinforcement in the learning process, where students not only receive information verbally but also directly observe the processes, events, or concepts being studied. This allows students to gain a more concrete and meaningful learning experience. Modifications to the learning strategy are carried out through adjustments to models, methods, media, and learning facilities and infrastructure to optimally support the achievement of learning objectives. Students' cognitive abilities are the main focus of this study, which include aspects of knowledge, understanding, application, analysis, evaluation, and creation according to Bloom's taxonomy. With the implementation of appropriate learning strategies, students are expected to be able to develop more active and critical thinking skills. The results of the study indicate that a modified direct learning strategy with the demonstration method has the potential to significantly improve students' cognitive abilities. Therefore, this approach can be used as an alternative, effective learning strategy to create a more interactive, engaging, and meaningful learning process.

This article examines umpasa as the determinant of the validity of the Mangalahat Horbo ritual and as a vehicle for transmitting the cultural values of the Batak Toba people from an anthropolinguistic perspective. Mangalahat Horbo is a buffalo sacrifice ritual that functions simultaneously as a cosmological, political, and linguistic event. This study employs a descriptive qualitative approach using three theoretical frameworks: Dell Hymes' (1974) SPEAKING model to analyze the ritual as a speech event, Roland Barthes' (1968) semiotics to dissect the denotative and connotative meanings of umpasa, and Kluckhohn's (1953) theory of cultural values and Sibarani's (2014) local wisdom theory to identify embedded cultural values. The findings reveal that umpasa operates on three simultaneous layers of meaning: pragmatic-performative, social-hierarchical, and cosmological-ecological. Umpasa is not merely an aesthetic ornament but a constitutive element of the ritual that shapes the social and cosmological reality of the Bius community. Eight cultural values are identified: communicative courtesy, adat knowledge transmission, self-restraint, collective responsibility, cultural preservation, cosmological reciprocity, distributive justice, and ecological harmony. This study affirms the urgency of anthropolinguistic documentation of Mangalahat Horbo before the Parhata masters of umpasa diminish further.

This study examines the concept of God’s holiness in Leviticus 10:1–7 through an exegetical approach to the event of the “strange fire” offered by Nadab and Abihu. The background of this research lies in the need to rediscover the true meaning of God’s holiness, which is often misunderstood in contemporary worship practices. The purpose of this study is to explore the theological meaning of the passage and its implications for faith and worship. The research uses a qualitative method based on literature study, focusing on historical, literary, and thematic analysis of the biblical text. The findings reveal that God’s holiness in this passage is absolute and cannot be violated without serious consequences. The action of Nadab and Abihu in offering unauthorized fire shows that worship is not only about sincere intention but also about obedience to God’s commands. The immediate divine judgment highlights that God’s holiness demands total reverence. Furthermore, this event serves as a warning for the community to maintain holiness in worship. In conclusion, God’s holiness in Leviticus 10:1–7 is radical and requires complete obedience from humanity. The implication of this study is the importance of cultivating reverence, discipline, and obedience in worship, ensuring that faith practices are aligned with God’s will rather than human preference.

Contract law recognizes the concept of force majeure as a mechanism to address extraordinary circumstances that hinder the performance of obligations, namely unforeseen events beyond the debtor’s control that may result in the release or suspension of obligations. However, this concept has limitations, as it does not encompass situations such as economic or monetary crises. In the development of international contract law, the UNIDROIT Principles of International Commercial Contracts 2016 (UPICC) introduce the concept of hardship as a response to fundamental changes in circumstances that affect the economic equilibrium of the parties. Although hardship has not been explicitly recognized in Indonesian law, it is considered more relevant for addressing such conditions.This study aims to examine the historical development of the concept of hardship and to analyze the implementation of its underlying values in Indonesian legal practice. The method employed is normative legal research, utilizing primary, secondary, and tertiary legal materials. The findings indicate that, despite the absence of explicit regulation within the national legal system, the values of hardship have been reflected in several court decisions through approaches grounded in fairness and contractual adjustment.The implication of this study is that the concept of hardship has the potential to be explicitly adopted into Indonesian contract law in order to fill existing legal gaps and provide a more adaptive solution to changing circumstances, particularly in addressing economic or monetary crises that fall outside the scope of the force majeure regime

Blasting is a critical method for overburden removal in open-pit coal mines, where fragmentation quality directly impacts loading efficiency and operational costs. This study aims to analyze the actual fragmentation resulting from overburden blasting at Pit 4 Middle of PT. Victor Dua Tiga Mega, Central Kalimantan, to predict fragmentation using the Kuz-Ram model, and to evaluate the conformity of both results against the company standard (boulder size ≤144.6 cm or ≥50 cm for analysis). The research employed a quantitative comparative method. Primary data included blasting geometry and photographs of muck piles from 10 blasting events, which were analyzed using WipFrag software to obtain actual fragmentation distribution. Secondary data comprised rock characteristics and explosive properties for Kuz-Ram prediction input. The results showed significant variation in actual boulder percentage (≥50 cm), ranging from 6.19% to 32.91% with an average of 16.05% (medium category). Statistical analysis revealed a very weak negative correlation (r = -0.21) between powder factor (PF) and boulder percentage, indicating that PF is not the dominant factor within the consistent application range (0.21-0.23 kg/bcm). Comparison with Kuz-Ram predictions showed that the model consistently over-predicted coarse material, with an average difference of +25.21%, suggesting the need for rock factor (A) recalibration. It is concluded that the blasting results are inconsistent, strongly influenced by uncontrollable factors such as geological conditions. Recommendations include geometri evaluation, particularly burden and spacing, and calibration of the Kuz-Ram model for more accurate future predictions.

Suspicious urban sound recognition is a critical component of intelligent public safety and urban monitoring systems, enabling the automated identification of anomalous acoustic events such as gunshots, sirens, and other security-sensitive sounds. However, existing deep learning approaches often struggle to simultaneously capture long-range temporal dependencies and global contextual relationships, particularly under noisy and acoustically complex urban conditions. This limitation can reduce reliability in safety-critical scenarios where missed detections carry significant risk. To address these challenges, this study proposes a Multi-Branch Bidirectional Long Short-Term Memory (BiLSTM) framework with Multi-Head Self-Attention (MHSA) for enhanced sequential and contextual feature modeling. Mel-frequency cepstral coefficients (MFCCs) are extracted from a curated subset of the UrbanSound8K dataset, comprising five suspicious sound classes, and used as input to the proposed architecture. The multi-branch design enables complementary temporal representations, while the self-attention mechanism provides lightweight contextual weighting of BiLSTM outputs. Experimental results demonstrate that the proposed model achieves a test accuracy of 95.59%, outperforming conventional Dense and LSTM-based baseline models under identical experimental settings. An ablation study further confirms the contribution of multi-branch integration and attention-based enhancement to overall performance. Class-wise evaluation reveals consistently high recall across all sound categories, particularly for safety-critical classes such as gunshots and sirens. These findings indicate that the proposed framework provides robust and reliable performance, making it suitable for real-time smart city surveillance and public safety applications.

This study aims to analyze fifth-grade students’ understanding of the water cycle concept at SD Muhammadiyah Sidayu using animated video assistance, as well as to describe supporting and inhibiting factors, identify obstacles faced by teachers and students, explain teachers’ efforts, and examine students’ responses in science learning. The research used a descriptive qualitative method with 23 fifth-grade students as participants. Data were collected through tests, questionnaires, interviews, and observations, and analyzed using data reduction, data presentation, and conclusion drawing. Data validity was ensured through triangulation of technique, source, and time. The results indicate that students’ understanding of the water cycle concept is categorized as moderate, with an average score of 69.43. Students are able to explain the definition and stages of the water cycle through images, classify events based on similarities in processes, and distinguish between evaporation and condensation. However, they still face difficulties in explaining the relationships between processes and in providing real-life examples related to the water cycle. Supporting factors include students’ interest and learning motivation, while inhibiting factors involve differences in comprehension abilities and students’ health conditions. Teachers face obstacles such as limited audio-visual facilities, shared LCD usage, and challenges in selecting appropriate animated videos. To overcome these issues, teachers use simple explanations, emphasize key points, replay videos, provide individual guidance, and assign diagram-based projects. Students’ responses are very positive, as animated videos increase their interest, attention, motivation, and conceptual understanding.

Hypertension is a condition characterized by systolic blood pressure ≥140 mmHg and diastolic blood pressure ≥90 mmHg. In Indonesia, the prevalence of hypertension showed an increasing trend in 2018, reaching 34.1% based on national survey data. Effective control of hypertension is essential to prevent long-term complications and acute cardiovascular events. Non-adherence to antihypertensive medication can increase cardiac workload. In addition to adherence to pharmacological therapy, unhealthy dietary patterns also contribute to the rising prevalence of hypertension. Therefore, adequate health literacy is required to support patients with hypertension in maintaining regular medication use and adopting healthy lifestyle changes, particularly in dietary management. To determine the relationship between health literacy and dietary patterns, as well as medication adherence among patients with hypertension. This study employed a non-experimental descriptive analytic design with a cross-sectional approach involving 113 respondents. Data were collected using questionnaires with ordinal scales and analyzed using the Gamma test. The results showed a p-value of 0.00 (<0.05) with correlation coefficients of R = 0.982 and R = 1.000, indicating a positive and very strong relationship between health literacy and dietary patterns, as well as medication adherence. There is a positive and very strong relationship between health literacy and dietary patterns and medication adherence among patients with hypertension.

The Indonesian National Army as a member of the Indonesian National Guard is at the forefront of Indonesia in the eyes of the public as an example and role model in discipline, ethics, and compliance with the law. However, in the reality of daily life, there are still TNI soldiers who commit traffic violations, such as driving a vehicle without having a Driver's License (SIM). This research includes empirical juridical research, or called field research, which examines the applicable legal provisions and compares them with the reality that occurs in society. The research method used was in the form of interviews with five relevant sources, then the data was analyzed descriptive-qualitatively to provide a comprehensive understanding. The results of the study showed that (1) law enforcement against TNI soldiers who committed traffic violations without a driver's license was checked according to the procedure of the rapid inspection event; no long inspection minutes are required, it is enough to use the minutes of traffic violations and road transportation or tickets from the military police; (2) Sanctions applied for minor traffic violations in the form of administrative disciplinary sanctions, including criminal prosecution of fines paid to military authorities and deposited into the state treasury. This reflects the balance between legal compliance and internal discipline of the TNI, as well as efforts to develop soldiers so that they remain an example for the community.

The death of a Madrasah Tsanawiyah (MTs) student allegedly linked to police action raises significant legal issues concerning the limits of the use of force and the construction of criminal liability. This study aims to reformulate the elements of assault resulting in death by integrating the objective element (actus reus) and the subjective element (mens rea) within the framework of the doctrines of dolus and culpa. It also seeks to develop a model of criminal liability analysis that is more transparent, accountable, and oriented toward the protection of a child’s right to life. This research employs a normative juridical method using statutory, conceptual, and case approaches, supported by a literature review of legislation, court decisions, and criminal law scholarship. Data are analyzed qualitatively through grammatical, systematic, and teleological interpretation. The findings indicate that proving the act and the resulting death alone is insufficient without clearly establishing the form of fault. The distinction between dolus eventualis and culpa lata constitutes a decisive factor in determining the classification of the offense and the degree of criminal liability. Ambiguity in identifying the spectrum of fault may lead to sentencing disparities and weaken the principle of geen straf zonder schuld (no punishment without fault). Therefore, this study proposes a reconstruction of the elements of the offense that places proof of mens rea at the center of assessing police accountability while ensuring the protection of the child’s right to life.

Accurate classification of rainfall intensity patterns is important for early warning systems, hydrometeorological risk assessment, and water resource management. Surface rain gauges have limited spatial coverage, so this study uses NOAA NEXRAD Level II radar data from the KTLX station in 2023. K-Means clustering was applied to identify rainfall intensity patterns from 30 randomly selected days, with scans stratified into four daily time intervals. Seven features were extracted from each radar sweep, including reflectivity statistics, convective and stratiform ratios, and rainfall coverage. The data were normalized and balanced before clustering. The optimal cluster count was determined through a combined evaluation of the Elbow Method, Silhouette Score, and Davies-Bouldin Index, yielding K=5 as the most representative configuration. Evaluation results demonstrated a Silhouette Score of 0.3871 and a Davies-Bouldin Index of 0.8599, indicating moderate cluster cohesion that reflects the inherent overlapping nature of rainfall intensity transitions in radar reflectivity data. The clusters represent rainfall regimes from non-precipitating conditions to intense convective events. These results support the use of K-Means for automated rainfall pattern recognition and flood forecasting applications. 

This study aims to examine the differences in stock prices before and after the Palestine-Israel ceasefire event in fast-food restaurant companies,  Pizza Hut and KFC. International-scale events may influence investor perceptions, as reflected in stock price movements in the capital market. This study employs a comparative quantitative approach using stock price data collected over 30 days before and 30 days after the ceasefire event. The analyzed data consist of secondary data processed through descriptive statistics, normality tests, and hypothesis testing. The findings indicate that the average stock price of PZZA increased after the event, whereas FAST experienced a decline in its average stock price. These results reveal differences in stock prices between the periods before and after the ceasefire event in both companies. The findings further suggest that geopolitical events are associated with changes in stock prices in the fast-food restaurant industry, although market responses differ across companies. Therefore, future studies are recommended to expand the scope of research objects and extend the observation period to obtain a more comprehensive understanding of market responses to international events.

This study explores the themes of poverty and educational values in the novel Al-Bidayah wa al-Nihayah by Naguib Mahfouz using the sociology of literature approach developed by Alan Swingewood. The novel is selected because it portrays the social reality of Egyptian society in the 1940s, particularly the lower class facing economic hardship, social inequality, and limited social mobility. This research employs a qualitative descriptive method through reading, note-taking, and library research. The data are drawn from narratives, dialogues, and events in the novel that reflect both poverty and educational values. The analysis is conducted by relating the textual content to its social and historical context. The findings indicate that poverty is not merely an economic issue but also a structural condition affecting the psychological, moral, and social aspects of the characters. Furthermore, the novel conveys educational values, including religious, moral, social, and cultural dimensions, which are closely linked to the realities of pre-revolutionary Egyptian society. Overall, Swingewood’s approach highlights the novel as a form of social critique as well as a medium for fostering readers’ social awareness.

This community service activity aims to describe the process and impact of the UMKM-Based Sepak Takraw Tournament for all of West Sumatra (Piala Limkos Sedunia) held in Nagari Sikucur, V Koto Kampung Dalam District, Padang Pariaman Regency, West Sumatra, as part of the Regular KKN Program of Universitas Negeri Padang for the January–February 2026 period. The method used is participatory action research with a qualitative descriptive approach. Activities were carried out for 30 days (January 9–February 8, 2026), involving 32 teams from 19 districts/cities across West Sumatra and hundreds of local UMKM actors. KKN students served as media partners, live streaming hosts on social media, and documentation committees. Results indicate that the tournament successfully stimulated the local economy with significant financial turnover through a 14-day UMKM bazaar, increased promotion of traditional sepak takraw sports, and strengthened social cohesion among nagari residents. The activity also contributed as an athlete development platform ahead of the West Sumatra Provincial Sports Week (PORPROV) 2028. The integration of sport events with UMKM empowerment has proven to be an effective strategy for improving rural community welfare.

The transfer of land rights is an important legal event that impacts legal certainty and the protection of ownership rights. In this process, notaries play a strategic role by drafting authentic deeds, which serve as the legal foundation for the transfer of land rights. This study aims to analyze the role of notaries in ensuring legal certainty in the transfer of land rights and to identify the responsibilities and challenges faced in practice. The research method used is normative legal research with a legislative and conceptual approach. The findings show that notaries play a crucial role in ensuring the formal and material validity of the land rights transfer agreement through the creation of authentic deeds. However, in practice, there are several challenges, such as discrepancies in land data, bad faith from the parties involved, and weak coordination among related institutions. Therefore, to achieve optimal legal certainty, it is necessary to enhance the professionalism of notaries and strengthen the land administration system. With these measures, it is expected that land rights transfers will proceed more smoothly and provide better legal protection for the public. ty.

Chronic Coronary Syndrome (CCS) is a contemporary term that replaces stable coronary artery disease (CAD) and describes a spectrum of clinical conditions resulting from chronic abnormalities of the coronary arteries. This condition is characterized by a mismatch between myocardial oxygen supply and demand that is transient and reversible, commonly presenting as stable angina pectoris. CCS contributes significantly to global cardiovascular morbidity and mortality, including in Indonesia. The underlying pathophysiology primarily involves atherosclerosis and microvascular dysfunction leading to myocardial ischemia. Diagnosis is established through comprehensive history taking, physical examination, and both invasive and non-invasive investigations such as electrocardiography, stress testing, and cardiac imaging. Risk stratification using pre-test probability plays a crucial role in guiding further diagnostic evaluation. The management of CCS aims to relieve symptoms and prevent adverse cardiovascular events through pharmacological and non-pharmacological approaches, as well as revascularization when indicated. Pharmacological therapy includes antianginal agents, antiplatelet drugs, and lipid-lowering agents, while lifestyle modifications such as smoking cessation, healthy diet, and regular physical activity are essential in preventing disease progression. With accurate diagnosis and comprehensive management, the morbidity and mortality associated with CCS can be reduced.

Proprioceptive sensor data, including inertial measurement units (IMU), joint encoders, and torque sensors, plays a critical role in state estimation for quadruped robots operating in dynamic and unstructured environments. However, these signals are often degraded by various sources of error, such as high-frequency noise, bias, drift, and contact-induced disturbances, which directly affect estimation accuracy and stability. This study presents a systematic analysis of sensor-specific noise characteristics and evaluates the effectiveness of preprocessing methods tailored to each sensor modality. Specifically, moving average filtering is applied to encoder signals to mitigate noise amplification during differentiation, while first-order low-pass filtering is employed for IMU and torque signals to suppress high-frequency noise. Experimental results on a publicly available quadruped dataset demonstrate that encoder velocity RMSE is reduced by 12.09%, high-frequency energy decreases by 59.63%, and signal-to-noise ratio (SNR) improves by 145.6%. However, variance reductions remain limited (3.39% for IMU and 4.05% for torque), indicating the persistence of impulsive, non-Gaussian noise caused by contact events. These findings highlight that linear preprocessing methods are effective for attenuating high-frequency noise but insufficient for handling non-Gaussian disturbances. The study provides practical insights into the effectiveness and limitations of preprocessing strategies, serving as a foundation for developing more robust signal processing and state estimation frameworks in quadruped robotics.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in supporting local and national economic development, particularly through employment generation and income distribution. Seasonal religious events such as Ramadan significantly influence consumption patterns and market dynamics, creating both opportunities and challenges for MSMEs. This study aims to analyze the implementation of the “Seri Ramadhan” phenomenon within the strategic management practices of MSMEs in Martapura, focusing on the periods before and after Ramadan. The research employed a qualitative descriptive approach with field study methods. Data were collected through in-depth interviews, direct observation, and documentation involving selected MSME actors in the culinary, fashion, and retail sectors. The findings indicate that prior to Ramadan, MSMEs emphasize strategic planning through product innovation, stock preparation, promotional intensification, and operational adjustments. After Ramadan, they conduct performance evaluations, inventory control, and strategic realignment to maintain business sustainability. The study highlights that Ramadan is not merely a short-term sales opportunity but also a strategic momentum integrated into broader business planning cycles. The implications suggest that adaptive and cyclical strategic management enhances MSME resilience and competitive advantage in seasonal markets.
