Hypertension is a chronic condition characterized by systolic blood pressure >130 mmHg and diastolic >80 mmHg, which can lead to serious complications such as stroke and heart failure if left unmanaged. This study aims to describe the application of warm water foot soak intervention in reducing blood pressure among hypertensive patients in the Dongkelan Kauman area. This was a descriptive study with a case study approach involving three elderlies with hypertension. The intervention was conducted for 20 minutes daily using warm water at a temperature of 38-40°C for three consecutive days. Data were collected through interviews and blood pressure measurements using a tensimeter before and after the intervention. The results showed a decrease in blood pressure in all three subjects after routinely implementing the intervention. The highest systolic reduction reached 15 mmHg, while the average diastolic reduction was 5 mmHg. Physiologically, warm water stimulates blood vessel vasodilation, which facilitates blood flow and reduces muscle tension. The study concludes that warm water foot soak therapy potentially effective as a non-pharmacological complementary intervention for controlling blood pressure in elderly patients with hypertension.

The purpose of this study is to investigate how Islamic Religious Education (PAI) instructors at Madrasah Diniyah Takmiliyah (MDT) Nurhidayatullah perceive incentive strategies as boosting student learning motivation. The poor learning motivation of students at non-formal Islamic educational institutions serves as the study's backdrop. Teachers must use a variety of tactics, including rewarding students. In this study, descriptive approaches are combined with a qualitative approach. Participant observation, documentation studies, and in-depth interviews were used to gather data. Purposive sampling was used to choose five PAI instructors from MDT Nurhidayatullah to serve as study informants. The Miles and Huberman approach, which covers data reduction, data presentation, and conclusions/verification, was used to analyze the data. The study's conclusions showed that instructors see incentive systems favorably and believe they are a useful tactic for boosting students' interest in and engagement with PAI learning. Verbal compliments, award stickers, extra credits, little presents, and public acknowledgment in front of the class are some of the prizes that are offered. Teachers believe that rewarding children may boost their intrinsic motivation, boost their self-esteem, improve the classroom environment, and promote healthy competition among students. However, teachers also identify several challenges, including the potential for students to become dependent on rewards, the need for fairness in reward distribution, and budget limitations. The implication of this research suggests that the reward method should be implemented systematically with clear criteria and gradually directed toward building students' intrinsic motivation in learning Islamic religious education.

The rapid transformation of education driven by globalization and technological advancement demands adaptive learning approaches that align with the characteristics of Generation Z learners. This generation is known for its curiosity, independence in thinking, and openness to diverse perspectives, yet it is also vulnerable to misinformation and negative online influences. Within the context of Islamic education, learning is not solely oriented toward cognitive development but also emphasizes the cultivation of moral values, particularly tolerance. This study aims to explore how contextual teaching methods can contribute to fostering tolerant attitudes among Generation Z students in Islamic educational settings. The research employs a qualitative approach through library research, utilizing a descriptive-analytical framework. Data were collected from various sources, including academic journals, books, and previous studies related to contextual learning, multicultural education, and Generation Z characteristics. The data collection technique involved document analysis, followed by content analysis procedures such as data reduction, categorization, and conclusion drawing. The findings indicate that contextual learning effectively promotes tolerance by engaging students in discussion, problem-solving, reflection, and real-life experiences. The integration of multicultural values and the role of teachers as facilitators and role models further strengthen this process. However, challenges remain, including limited teacher understanding, the persistence of conventional methods, inadequate supporting facilities, and the influence of social media. Overall, contextual learning presents a relevant strategy for developing open-minded, balanced, and socially adaptive Generation Z learners.

Industrial waste management is an essential part of environmental protection and management efforts in Indonesia. Industrial development contributes positively to economic growth, but it also creates risks of environmental pollution when waste is not managed properly and in accordance with legal regulations. This study aims to analyze legal regulations concerning industrial waste management in Indonesia, evaluate the compliance level of PT Selatan Jadi Jaya with applicable laws and regulations, and examine law enforcement efforts and accountability mechanisms for violations affecting the environment. The research applies an empirical normative method using statutory and field approaches. Data were collected through literature studies of legislation, scientific journals, and legal doctrines, supported by observations and interviews with related parties. The findings show that industrial waste management has been comprehensively regulated under Law Number 32 of 2009 and Government Regulation Number 22 of 2021. However, implementation still encounters obstacles such as weak supervision, limited legal awareness among business actors, and economic considerations affecting corporate compliance. PT Selatan Jadi Jaya has fulfilled several administrative obligations but still requires improvement in substantive waste management practices. Effective supervision, consistent law enforcement, and stronger corporate commitment to sustainability and environmental responsibility are therefore necessary to achieve optimal environmental protection.

This study is motivated by the importance of understanding theology not merely as a theoretical concept, but as a reflection of faith that is lived within the cultural context of society. In the context of the Dayak community in Central Kalimantan, there is a close relationship between cultural values and spiritual life, thus requiring a theological approach that can bridge the two. This study aims to analyze the praxis model in contextual theology and its application in the life of the Dayak community. The method used is a descriptive qualitative approach through literature study by examining various relevant sources. The results show that the praxis model emphasizes the relationship between lived experience, faith reflection, and concrete action. Cultural values such as togetherness and mutual cooperation are in line with Christian teachings; however, there are also traditional practices that create tension with faith. The church plays an important role in addressing this through a dialogical and reflective approach. The implications of this study indicate that the application of the praxis model enables believers to live out their faith in a contextual, relevant, and transformative way in daily life without losing their cultural identity.Top of Form

Scientific articles not only function as a medium for conveying information but also as a representation of the author’s academic credibility and intellectual authority within the scientific community. In academic writing, language plays a crucial role in shaping the author’s identity, reliability, and scholarly position. This research aims to conceptually examine the relationship between linguistic choices and the construction of authority in Indonesian-language scientific articles. The study employs a library research method with a critical discourse analysis approach toward various references related to functional linguistics, discourse studies, and ethics in academic writing. The findings indicate that academic authority is constructed through several linguistic aspects, including lexical precision, grammatical objectivity, cohesion and coherence of ideas, as well as a careful epistemological attitude that remains open to alternative interpretations and scientific dialogue. In addition, the use of formal, systematic, and evidence-based language contributes significantly to strengthening the legitimacy of scientific arguments. Within this framework, language is not merely a communication tool used to present ideas, but also an instrument for legitimizing knowledge and reinforcing the author’s credibility, reliability, and authority in academic discourse. Therefore, mastery of academic language becomes an essential component in producing quality scientific articles.

This study analyzes signs and symbols in Katherine Mansfield’s short story “The Doll’s House” (1922) using Charles Sanders Peirce’s semiotic approach. The study is descriptive qualitative in nature, employing data collection techniques such as close reading and note-taking. The analysis was conducted by classifying signs based on Peirce’s theory, icons, index, and symbols, through the triadic model (representamen, object, interpretant). The results of the analysis indicate that the doll’s house functions as both an icon and a symbol of social status and the false luxury of the upper class. Elements such as the smell of paint and the appearance of the Kelvey sisters serve as indices of social inequality. Meanwhile, the small lamp is the strongest symbol representing hope, warmth, and the possibility of transcending social class boundaries. Through this short story, Mansfield critiques class prejudices learned from childhood while conveying a message of empathy across social classes.

This study aims to identify and determine the conversational implicatures that arise in the comment section of Instagram @kementeriankegelapan, which discusses the issue of poisoning related to the “Makanan Bergizi Gratis” (Free Nutritious Food) program. The research method used is qualitative with a pragmatic approach, which not only examines the surface meaning but also considers the context of the utterances. The theory applied in this study is the theory of implicature, specifically conversational implicatures. The data were obtained from the comment section of Instagram @kementeriankegelapan on posts concerning the poisoning issue of MBG (Free Nutritious Food). Data collection was conducted using the listening method (Simak) and the advanced technique of listening-without-participating in speech (simak libat bebas cakap). Data analysis used the referential identity method (padan referensial) with the advanced technique of selecting defining elements (pilah unsur penentu). The findings show that there are eight pieces of data in the form of conversations, each containing an idea or topic that specifically responds to the satirical post uploaded on the @kementeriankegelapan account regarding the MBG food-poisoning issue. The topics include: Azab (punishment), Tunggangan di Akhirat (conveyance/punishment in the afterlife), shouting “Long live Jokowi!”, MBG as a way to alleviate poverty, color codes, preventing fights/gang fights, maggots, and “licking”/being servile. Each of these topics has its own implicature.

This study was conducted in response to the increasingly complex nutritional issues among adolescents, reflected in the coexistence of undernutrition and overnutrition within the same population, which are closely associated with dietary consumption patterns. The research aimed to investigate the relationship between diet quality and the nutritional status of students at SMAN 9 Surabaya. A quantitative approach with a cross-sectional design was employed, involving 85 participants selected based on the estimated sample requirement for correlation analysis. Dietary intake data were collected using two non-consecutive 24-hour food recalls and subsequently assessed using the Diet Quality Index for Adolescents (DQI-A). Nutritional status was determined through BMI-for-age calculations in accordance with the World Health Organization standards. Data analysis was performed using correlational testing and Chi-Square analysis to identify differences in proportions. The findings revealed that the respondents’ diet quality remained suboptimal, while most students were categorized as having normal nutritional status, although cases of undernutrition and overnutrition were still identified. A significant association was found between diet quality and nutritional status (p = 0.001), indicating that better diet quality tended to be linked with normal nutritional status. Based on the DQI-A components, dietary quality demonstrated a significant relationship with nutritional status (p = 0.007), whereas dietary diversity (p = 0.597) and dietary equilibrium (p = 0.507) showed no significant associations. These findings highlight that diet quality, particularly food selection patterns, plays an important role in determining adolescent nutritional status. Therefore, improving nutritional conditions requires more intensive nutrition education interventions focusing on healthy food choices, increased fruit and vegetable consumption, and controlled intake of sugar, salt, and fat, supported consistently by both individuals and the school environment.

The concept of mahabbah (divine love) is one of the pinnacles of achievement in the Sufism tradition that marks the existential closeness between man and God. In the context of prophetic literature, this concept is not only present as an individual spiritual experience, but also undergoes a transformation into a communicative aesthetic and ethical discourse. This study aims to examine the transformation of the concept of mahabbah in Kuntowijoyo's poems by placing them in a prophetic literary framework that emphasizes the dimensions of transcendence, humanization, and liberation. The method used is literary hermeneutics with an interpretive approach to uncover the layers of symbolic meaning in the text. The data is in the form of selected poems that represent the themes of spirituality, Divine love, and human relationship with God. The results of the study show that the concept of mahabbah in Kuntowijoyo's poems undergoes a transformation from the concept of classical Sufism which is esoteric in nature to a more contextual and communicative symbolic expression. This transformation is seen through the use of symbols of love, longing, sincerity, and sacrifice that represent not only man's vertical relationship with God, but also a horizontal relationship with fellow humans. Thus, mahabbah in prophetic literature does not stop at the mystical dimension, but moves towards social praxisis oriented towards human values. This research confirms that poetry functions as a dialectical medium between spiritual experience and social reality, as well as a means of transforming transcendental values into concrete life.

This study is based on the increasingly rapid development of the knowledge-based economy, where human capital is now regarded as one of the important assets in creating a company’s competitive advantage, especially in the energy and oil and gas sectors in Indonesia. This study aims to determine the effect of human capital and labor intensity on corporate financial performance, which is proxied by Return on Assets (ROA) during the 2021–2024 period. The research method used is a quantitative approach with multiple linear regression analysis. The research data were obtained from sample companies selected using a purposive sampling technique. The results of the study show that human capital, proxied by Value Added Human Capital (VAHU), has a positive and significant effect on corporate financial performance. These findings indicate that good human resource management is capable of increasing the company’s profitability level. On the other hand, labor intensity is proven to have a negative and significant effect on financial performance. This indicates that a high level of company dependence on labor, without being balanced by operational efficiency, can reduce the company’s ability to generate profits. In addition, simultaneously both variables are able to explain 74.5% of the variation in Return on Assets (ROA), so it can be concluded that human capital and labor intensity have a considerable contribution to corporate financial performance. Based on these results, companies need to prioritize improving the quality and competence of the workforce rather than merely focusing on increasing the number of employees. This step is important to maintain the stability of corporate financial performance in the post-pandemic era. In addition, companies also need to effectively control labor costs so that a decline in net profit margins can be avoided.

Blast hole drilling is an initial stage that plays a critical role in determining the success of blasting activities in mining and construction operations. Drilling quality directly affects rock fragmentation, drilling equipment efficiency, drilling equipment productivity, as well as blasting safety and costs. This study aims to analyze the influence of drilling parameters on blast hole quality, including hole diameter, drilling depth, hole inclination, and the suitability of drilling patterns with respect to the planned blasting design. The research methodology involves field observations, actual measurements of drill holes, and analysis of data obtained from drilling and blasting productivity. The results show that deviations in hole depth and direction can lead to irregular distribution of blasting energy, resulting in suboptimal rock fragmentation and an increased potential for flyrock and overbreak. In addition, the selection of appropriate drilling methods and equipment based on rock mass characteristics has been proven to improve productivity and blast hole quality. Therefore, controlling drilling parameters and implementing proper operational procedures are essential to enhance the overall effectiveness and productivity of blasting activities. This study is expected to serve as a reference for the planning and evaluation of blast hole drilling activities to achieve more efficient, safe, and economical operations.
