Educator certificates are official documents that play a crucial role for teachers, as they serve as legal proof of professional competence and are required for various administrative purposes, such as professional allowance applications, promotion, transfer, and institutional accreditation. Along with the increasing number of educators in Indonesia, the volume of educator certificate data managed by educational institutions has also grown significantly. However, certificate management is still largely conducted in a conventional manner, functioning merely as digital or physical archives without an effective search mechanism, resulting in inefficiencies and difficulties in retrieving relevant documents. Therefore, an information retrieval approach is needed to support fast and accurate document searching. This study aims to analyze and implement an information retrieval system for educator certificates using the Cosine Similarity method. The research data consist of educator certificate documents, including professional educator certificates, training certificates, and competency certificates. The retrieval process involves text preprocessing, term weighting using TF-IDF, and similarity measurement using Cosine Similarity. The results show that document d1 (Professional Mathematics Educator Certificate) has the highest similarity value to the query “educator certificate,” as it contains all query terms with relatively high TF-IDF weights. Document d3 ranks second due to partial term similarity, while document d2 has the lowest similarity value because it shares only one common term with the query. These findings indicate that the Cosine Similarity method is effective in ranking educator certificate documents based on their content relevance in an objective and measurable manner. The proposed system can improve the efficiency and accuracy of educator certificate document management and retrieval in educational institutions.

The lexical data were analyzed using the intralingual and extralingual comparison methods. The findings reveal significant lexical differences between the two speaker groups. Female student tend to use more varied, complete, and expressive lexical forms, including full words and phrasal expressions. In contrast, male students show a tendency to use shorter, more efficient lexical forms dominated by abbreviations and rough expressions. These findings highlight that gender functions as a linguistic marker shaping distinct communicative patterns among adolescents, with female students prioritizing social expression and affection, while male students emphasize practicality and efficiency in language use.

Honesty (ṣidq) is a fundamental moral value in Islam that serves as the foundation for personal integrity and social ethics. In the current era of globalization and growing materialistic culture, this value faces serious challenges as societal orientation shifts from moral virtue to economic achievement and social image. This study employs a narrative review method, analyzing recent literature on moral education, Islamic ethics, and contemporary social dynamics. The findings reveal that honesty functions not only as a personal virtue but also as a social force that strengthens public trust and national stability. However, the global wave of materialism has weakened the internalization of ṣidq, especially among younger generations. Restoring honesty as the moral identity of the nation requires synergy among character-based education, spiritual reinforcement, and public policies that promote transparency and integrity. The recontextualization of honesty through Islamic spiritual principles and Rokeach’s value theory offers a path toward moral recovery for Indonesian society amid the global challenges of the 21st century.

This study compares the scalability and maintainability of three prominent programming paradigms-functional programming (FP), object-oriented programming (OOP), and declarative programming (DP)-in the context of distributed data processing systems. The research aims to evaluate how each paradigm performs under increased data volume and its ability to handle complex operations, while also assessing the ease of maintenance through code readability, modularity, and the flexibility of updating and debugging. The study employs a comparative experimental design, implementing identical data processing tasks, such as data aggregation, filtering, and transformation, across each paradigm. Key findings indicate that FP and DP outperform OOP in terms of scalability, with their stateless nature and high-level abstractions enabling efficient parallel processing and task distribution. FP, with its emphasis on immutability and concurrency, and DP, with its focus on describing desired outcomes rather than implementation specifics, both demonstrate superior performance in handling large datasets. However, while OOP excels in modularity and flexibility, its reliance on mutable state and shared resources hampers its scalability in distributed environments. In terms of maintainability, both FP and DP offer clearer, more maintainable code due to their abstraction levels, making them easier to update and extend. OOP, while modular, presents challenges in managing mutable state, complicating maintenance. This paper concludes with practical recommendations for developers on when to use each paradigm based on system requirements and suggests areas for future research, such as hybrid paradigms and long-term maintainability studies in real-world applications.

Diabetes mellitus (DM) is a global health problem characterized by increased blood glucose levels. Type 2 diabetes mellitus (T2DM) accounts for 90-95% of all diabetes cases and is characterized by insulin resistance. Persistent hyperglycemia in patients with T2DM increases the risk of various complications, including renal dysfunction. Therefore, monitoring HbA1c levels is important for assessing long-term glycemic control and preventing complications, one of which is impaired kidney function that can be detected through increased blood creatinine levels. To analyze the relationship between HbA1c levels and blood creatinine levels in type 2 diabetes mellitus patients at RSUD ODSK North Sulawesi Province. This study used an observational analytic design with a cross-sectional approach. This study was retrospective using secondary data in the form of medical record data for the period February 2024-August 2025. This study used a total sampling method with 71 patients who met the inclusion criteria. The findings showed that the majority of patients had HbA1c levels >6,5%, while most blood creatinine levels were within the normal range. Based on the results of the Spearman-Rank correlation test, a significance value of 0.040 (p-value <0.05) was obtained. There is a significant relationship between HbA1c levels and blood creatinine levels, with a negative correlation strength in patients with type 2 diabetes mellitus at RSUD ODSK North Sulawesi Province.

This study examines the criteria of disgraceful conduct in the dismissal mechanism of regional heads in Indonesia following Constitutional Court Decision No. 2/PUU-XX/2022. The decision underscores the necessity of a constitutional interpretation of the requirement “never having committed disgraceful conduct” in order to prevent abuse of power and political injustice in regional governance. Employing a normative legal research method, this study analyzes primary legal materials, including Constitutional Court decisions and statutory regulations, as well as secondary legal literature. The findings reveal that the notion of disgraceful conduct had previously functioned as a vague norm, enabling subjective and politically motivated interpretations, particularly by regional legislative bodies. The Constitutional Court, through its decision, transformed this open norm into a more limitative and objective standard by specifying concrete forms of conduct, such as gambling, intoxication, drug abuse, adultery, and other serious violations of decency. Furthermore, the Court emphasized that allegations of disgraceful conduct must be supported by clear, lawful, and verifiable evidence, in line with the principles of due process of law. This reformulation strengthens legal certainty, protects the political rights of elected regional heads, and preserves the stability of local governance. The study recommends legislative synchronization through amendments to the Regional Government Law and the issuance of judicial guidelines to ensure uniform standards of proof in dismissal proceedings, thereby reinforcing constitutional justice and the rule of law in Indonesia.

Finally, the study suggests future research directions, including the refinement of multi-method approaches and the need for longitudinal studies to better understand the long-term impact of EIS on innovation outcomes.

Chronic kidney disease (CKD) is a global health problem with continuously increasing prevalence and mortality. This condition is characterized by a progressive and irreversible decline in kidney function, which is clinically assessed using the estimated glomerular filtration rate (eGFR) as one of the main parameters for staging and monitoring disease progression. Red blood cell distribution width (RDW) is a hematological parameter that reflects the degree of variation in erythrocyte size. In patients with CKD, elevated RDW levels are often associated with oxidative stress and chronic inflammation, which may accelerate kidney damage and increase mortality risk. To analyze the correlation between RDW and eGFR values in patients with chronic kidney disease at ODSK Hospital, North Sulawesi Province. This study used an analytical observational design with a cross‑sectional approach. It was conducted retrospectively using secondary data from the medical records of CKD patients at ODSK Hospital, North Sulawesi Province, from February 2024 to August 2025. This study used a total sampling method with 189 CKD patients who met the inclusion and exclusion criteria.  Based on Spearman-rank correlation analysis, the p‑value obtained was 0.129 (>0.05). There was no significant relationship between RDW and eGFR values in CKD patients at ODSK Hospital, North Sulawesi.Province.

Psychological well-being is a fundamental construct in individual development; however, within guidance and counseling practice it is often positioned merely as an indirect outcome of problem-focused interventions. Philosophically and empirically, psychological well-being holds substantial potential to be established as a primary goal of guidance and counseling services. This article aims to examine psychological well-being as an axiological objective of guidance and counseling through a philosophy of science perspective supported by recent empirical evidence. The method employed is a literature review of scholarly publications from the last eight years retrieved through Google Scholar. Eleven relevant articles were selected and analyzed using thematic synthesis to identify conceptual patterns and empirical findings related to psychological well-being in the context of guidance and counseling. The results indicate that psychological well-being is conceptualized as a long-term developmental outcome reflecting holistic human functioning, encompassing dimensions such as autonomy, purpose in life, personal growth, environmental mastery, self-acceptance, and positive relations with others. Various guidance and counseling interventions particularly those based on mindfulness and positive psychology interventions have been empirically demonstrated to effectively enhance eudaimonic well-being. From an axiological perspective, psychological well-being possesses strong value foundations and aligns with the ethical mandate of guidance and counseling to promote optimal human development. This article underscores the necessity of a paradigm shift in guidance and counseling practice, moving from a predominantly problem-oriented approach toward a well-being-oriented framework in which psychological well-being is positioned as a central and explicit goal of professional services.  

Individuals with mental disabilities commonly experience difficulties in self-awareness and emotion regulation, which negatively affect social functioning and psychosocial well-being. These conditions were also observed among beneficiaries in the assisted community, who demonstrated limitations in recognizing emotions, expressing feelings, and engaging in social interactions. This community service program aimed to strengthen self-awareness and emotional regulation skills among individuals with mental disabilities through a psychosocial approach. The program employed activity-based psychoeducation using participatory and supportive methods, including emotional recognition training, self-reflection, positive emotional stimulation, and structured group support. The results indicated improvements in beneficiaries’ ability to identify and express basic emotions, increased self-confidence, enhanced emotional stability, and more active social participation. Qualitative observations revealed behavioral changes from passive tendencies to more responsive and cooperative involvement in group activities. These findings suggest that activity-based psychosocial interventions are effective in improving psychosocial well-being among individuals with mental disabilities.

Pulmonary tuberculosis (TB) remains a major public health problem in Indonesia. Despite the implementation of national TB control programs through the Directly Observed Treatment Shortcourse (DOTS) strategy, treatment success continues to face significant challenges, particularly related to patient adherence to anti-tuberculosis drug (ATD) therapy. Non-adherence to TB treatment can lead to treatment failure, disease relapse, and the development of drug-resistant tuberculosis, thereby increasing the overall burden of the disease.Treatment adherence in TB patients is influenced not only by medical factors but also by social and behavioral determinants. Family support plays a crucial role in encouraging patients to comply with treatment regimens by providing motivation, reminding medication schedules, and offering emotional support throughout the long duration of therapy. Patients who receive adequate family support tend to demonstrate higher levels of treatment adherence compared to those with limited support.In addition, the use of herbal medicine as a preventive and supportive health measure is common among the Indonesian population. Herbal medicine is often utilized to enhance immune function, reduce medication side effects, and improve patient comfort during TB treatment. However, the use of herbal remedies without proper medical guidance may lead to misconceptions regarding standard TB therapy.Therefore, it is important to examine the relationship between family support and the use of herbal medicine as preventive measures with treatment adherence among pulmonary TB patients in primary healthcare settings. Such evidence is expected to support a comprehensive family medicine approach and strengthen TB control programs in primary care services.

Postoperative pain is a common physiological response following surgical procedures, and its suboptimal management can have physiological and psychological effects, including sleep disturbances, decreased functional capacity, increased anxiety, and deterioration in quality of life. This scoping review aims to describe the empirical evidence regarding the effectiveness of music therapy in reducing the intensity of postoperative pain in surgical patients. A systematic search was conducted through four major databases (ScienceDirect, PubMed, Neliti, and Google Scholar) using Boolean operators and keywords such as ‘postoperative pain,’ ‘music therapy,’ and ‘pain scale.’ Inclusion criteria included articles published in the last decade, in English or Indonesian, and available in full text format. In accordance with PRISMA-ScR guidelines, this review analysed 10 articles. The synthesis of results showed that music therapy consistently reduced pain intensity, anxiety, and analgesic requirements through mechanisms such as increased endorphin secretion, decreased stress hormone levels, and activation of the gate control theory. Typically administered for 15–30 minutes, music therapy is a safe, cost-effective, and patient-acceptable non-pharmacological modality. This intervention is recommended as an adjunct component in perioperative pain management in nursing practice, although further standardised research is needed to improve consistency.
