Hypertension and diabetes mellitus are two highly prevalent non-communicable diseases that often coexist as comorbidities, significantly increasing the risk of cardiovascular complications. The coexistence of these conditions accelerates the onset of atherosclerosis, diabetic nephropathy, and kidney failure, thereby requiring more comprehensive clinical management. One of the key parameters in diabetes management is fasting blood glucose (FBG), which reflects the balance of glucose metabolism after a fasting period. Chronic hyperglycemia is known to contribute to endothelial dysfunction, increased peripheral vascular resistance, and activation of the sympathetic nervous system and renin-angiotensin-aldosterone system, ultimately leading to elevated blood pressure. This study employed a systematic literature review approach, analyzing articles published between 2021 and 2025. Narrative synthesis was conducted across various study designs, including cross-sectional, cohort, and meta-analysis studies. The findings indicate that most studies support a significant association between FBG levels and blood pressure, although some reported varying results. Cohort studies provide stronger evidence that elevated FBG increases the risk of new-onset hypertension. Age, treatment adherence, and lifestyle factors were also identified as confounding variables influencing outcomes. Overall, the evidence highlights that glycemic control through FBG monitoring is essential in managing hypertension among diabetic patients. Multidisciplinary strategies, patient education, and strengthening of primary healthcare services are required to reduce cardiovascular risks. Longitudinal studies are recommended to deepen the understanding of the relationship between FBG and blood pressure and to reinforce the scientific basis for evidence-based clinical interventions.

Thaharah represents a core principle within Islamic teachings, encompasses both bodily cleanliness and spiritual sanctity, and functions as an essential requirement for the proper observance of acts of worship, including prayer, tawaf, and the recitation of the Qur’an. This concept extends beyond ritual practice, reflecting a manifestation of faith that encourages Muslims to maintain personal hygiene, environmental cleanliness, and spiritual closeness to Allah SWT. This study aims to explore and critically examine the concept of thaharah in a comprehensive manner, clarify its role within Islamic religious practices, and assess its relevance in fostering clean lifestyle behaviors and appropriate worship practices in accordance with Islamic legal principles in contemporary society. Conceptually, thaharah is divided into two main forms: purification from ritual impurity (hadas) through ablution (wudu), ritual bathing (ghusl), or dry purification (tayammum), and purification from physical impurities (najis) by cleansing the body, clothing, and surrounding environment. The normative foundation of thaharah is reinforced by textual evidence, including Surah Al-Ma’idah verse 6 and prophetic traditions that emphasize cleanliness as an integral part of faith. Thus, thaharah offers a holistic perspective on cleanliness that integrates both worldly and spiritual dimensions of Muslim life.

The study aimed to find out the nature of the budget, know the modern techniques of preparing and implementing the budget, and the consequences of preparing budget based on the modern techniques on performance of government. The descriptive-analytical approach was used to meet the objectives and hypotheses of the research. The data was gathered through a questionnaire whereby 60 questionnaires where distributed to a sample population of accountants working in the Financial Affairs Department at the General Directorate of Education in Wasit Governorate (Iraq), and 57 questionnaires were collected to establish the views of the accountants regarding the effect of preparing and implementing budgets under the modern techniques on the government performance. This paper came up with a number of conclusions. Preparation of the general budget of the state is a technical and political process that involves and is involving different actors in the state. The budget preparation process is a technical process since it involves numerous key calculations that can be used to quantify the anticipated revenues, the cost of activities likely to be obtained in the year and estimation of the planned expenditures. The process of preparing the budget through the traditional ways (line-item budgeting) does not contribute to the optimal planning and budget allocation of the state and, therefore, the fulfillment of the goals laid out by the countries. This paper advises on the need to focus on the current approaches in the budget preparation because they enhance governmental performance, enhance the effectiveness and efficiency of state expenditures, strive to diversify the income, and convert the policies and goals of the state into a definite and actualized reality on the ground, with the help of standards and indicators that modern means of preparing the budget have offered. And to act to modernize the budget system in Iraq, profiteering with the experience of other countries in this domain, and that modernization be a progress, commencing with the budgeting of some ministries or departments within ministries and bodies gradually with the aim of acquiring more experience and expertise, and then meet the impediments which will emerge to proceed to a complete transition.

Password security is a critical component in protecting information systems, as passwords are often the primary target of various attacks, particularly brute force attacks. A brute force attack works by systematically attempting all possible character combinations until the correct password corresponding to a stored hash value is found. Therefore, the choice of an appropriate hash algorithm plays a significant role in determining a system’s resistance to such attacks. This study aims to analyze and compare the password cracking time of MD5, SHA-256, and SHA-512 hash algorithms under brute force attack scenarios. The research methodology involves generating hash values from a set of test passwords using each hash algorithm, followed by conducting brute force attacks to recover the original passwords based on the generated hash values. The collected data are analyzed by measuring the time required to crack passwords for each algorithm. The results indicate that MD5 has the fastest cracking time compared to SHA-256 and SHA-512, indicating a lower level of resistance to brute force attacks. SHA-256 demonstrates better security than MD5 but remains less resistant when compared to SHA-512. The SHA-512 algorithm requires the longest cracking time, reflecting the highest level of resistance to brute force attacks among the tested algorithms. In conclusion, hash algorithms with larger bit lengths provide stronger protection against brute force attacks and are more suitable for secure password storage in information systems.

The increasing consumption of packaged food products in Indonesia reflects modern lifestyle changes but simultaneously raises public health concerns related to high calorie, sugar, and fat intake. Nutritional information presented on food labels consists of multiple interrelated variables, making it difficult to identify dominant nutritional factors that characterize packaged food products. This study aims to apply Principal Component Analysis (PCA) to reduce the dimensionality of nutritional data and to map the nutritional characteristics of packaged food products in Indonesia. The research employs a quantitative exploratory approach using secondary data obtained from nutrition facts labels of 1,651 packaged food products. Seven nutritional variables were initially analyzed, namely total energy, protein, total fat, total carbohydrates, sugar, sodium, and dietary fiber. Data preprocessing included data cleaning, Z-score standardization, and iterative variable selection based on the Kaiser-Meyer-Olkin (KMO) measure and Bartlett’s Test of Sphericity to ensure sampling adequacy and sufficient correlation among variables. Variables with low sampling adequacy and perfect multicollinearity were eliminated, resulting in five variables retained for the final PCA model. Principal components were extracted using the eigenvalue greater than one criterion and confirmed through a scree plot, followed by Varimax rotation to enhance interpretability. The results indicate the formation of two principal components explaining approximately 69.7% of the total variance. The first component represents energy density and macronutrient richness, while the second component reflects carbohydrate-related characteristics, particularly the contrasting pattern between sugar and dietary fiber. Biplot visualization further illustrates product distribution based on these components. The findings demonstrate that PCA effectively simplifies complex nutritional information and provides a clear nutritional mapping of packaged food products, offering practical insights for consumers, producers, and policymakers in supporting healthier food choices in Indonesia.

This article examines the role of context and underlying assumptions in the formulation of econometric models for economic policy analysis. While econometric models are widely employed to support policy decisions, their construction is often treated as a purely technical process, overlooking the contextual factors that shape variable selection, model specification, and interpretation of results. This study explores how institutional settings, policy objectives, and behavioral considerations influence the assumptions embedded in econometric modeling. By drawing on policy documents, academic literature, and illustrative cases from applied economic research, the article highlights how implicit assumptions may affect the validity and relevance of econometric outcomes. The analysis emphasizes that econometric models are not value-neutral tools but are shaped by theoretical choices and contextual judgments made during their formulation. Understanding these dimensions is crucial to avoid misinterpretation of empirical findings and to enhance the usefulness of econometric analysis in policymaking. The study contributes to the methodological discussion in applied econometrics by encouraging greater transparency and reflexivity in model construction, particularly in the context of economic policy evaluation.

Early childhood education is a fundamental phase in the formation of children's character, literacy skills, and social skills. However, children's basic literacy skills in various regions of Indonesia, including Aisyiyah 2 Aimas Kindergarten, Southwest Papua, are still relatively low, exacerbated by limited learning media, conventional teaching approaches, and teachers' lack of understanding of inclusive education and positive discipline. This study aims to analyze the implementation of basic literacy training with inclusive education and its impact on improving teacher competence. The method used is a one group pretest in the context of community service, involving six teachers as subjects. The program is carried out through three stages: pre-training (observation, interview, and pretest), training (literacy materials based on the DUBT model—Listen, Speak, Read, Write; inclusive education; and positive discipline), and post-training (posttest, classroom observation, reflection, and mentoring). The results showed a significant increase in teacher competence, as shown by the increase in the average pretest score from 57.5 to 84.8 in the posttest. In addition, 83% of teachers are able to implement literacy practices such as reading picture stories, letter cards, reading corners, and dialogue interactions with children. Teachers also began to show acceptance of children's diversity and applied positive discipline without punishment. These findings show that inclusion-based literacy training is effective in improving teachers' pedagogical knowledge and practices. This research emphasizes the importance of developing adaptive, humanist, and equitable literacy as the foundation of early childhood learning.

This study examines the economic dynamics experienced by migrant women through the perspective of abstract painting as a medium for personal and social reflection. The study uses a qualitative method with an artistic research approach, which departs from the researcher's personal experience as a migrant woman facing increasingly complex economic realities. The rising cost of living, financial constraints, and intertwined academic demands create pressure not only on material aspects, but also on psychological, emotional, and mental conditions. This situation demands adaptation strategies, resilience, and the ability to survive in the face of uncertainty in migrant areas. The dynamics of these experiences are then translated into visual language through an abstract expressionist approach utilizing mixed media techniques. Dynamic line elements, contrasting colors, bubble textures, and layers of material are used as symbols of the tension, struggle, and economic instability experienced by the subjects. The research findings show that abstract painting functions not only as a means of personal expression, but also as a medium for social reflection that records and articulates the experiences of migrant women who are often marginalized. This research contributes to the enrichment of contemporary art discourse, particularly in presenting visual narratives that voice economic issues and women's life experiences in a critical and reflective manner.

This study examines the contribution of excise revenue from alcoholic beverages to Indonesia’s state revenue during the period 2021–2023. Alcoholic beverages are classified as excisable goods due to their potential negative impacts on public health and social order, making excise duty an important fiscal instrument for both revenue generation and consumption control. The objective of this research is to analyze the trend and magnitude of excise revenue from alcoholic beverages and its role in supporting national income. This study employs a quantitative descriptive method using secondary data obtained from official government publications, including reports from the Ministry of Finance and the Directorate General of Customs and Excise. The data are analyzed by comparing annual excise revenue figures and identifying their contribution to total excise and state revenue over the observed period. The findings indicate that excise revenue from alcoholic beverages showed a fluctuating but generally increasing trend from 2021 to 2023, reflecting post-pandemic economic recovery and adjustments in excise tariff policies. Despite its relatively smaller share compared to tobacco excise, alcoholic beverage excise consistently contributed to state revenue and demonstrated fiscal potential. The study implies that effective excise policy on alcoholic beverages can support state revenue while simultaneously serving as a regulatory tool to control consumption and mitigate social and health risks.

This article examines the integration of constructivist theory in Christian Religious Education (PAK) by emphasizing the role of personal experience as the basis for faith formation. Through a reflective-theological qualitative approach, this research combines the constructivist thought of Piaget, Vygotsky, and Fosnot with a theological perspective on the incarnation of Christ and the work of the Holy Spirit. The analysis suggests that constructivism can be theologically reinterpreted into a new paradigm called the Theo-Constructive Epistemology of Incarnational Faith, in which faith is not simply taught cognitively, but is constructed through life experiences infused by the presence of God. This approach emphasizes that the learning of faith is relational, participatory, and contextual, in line with the nature of God who works in human history. The findings of this study offer a new direction for PAK praxis to be more relevant to digital contexts and cultural plurality, without losing its theocentric orientation. Thus, the integration of constructivism and incarnational theology opens up space for more dynamic, contextual, and transformative learning of faith, while strengthening the relevance of PAK in facing the challenges of modern times.
