Diesel engines are widely used in the transportation and industrial sectors due to their high thermal efficiency and good operational durability. However, increased fuel consumption due to inefficiency of the injection system remains a common problem. Injector characteristics, particularly nozzle diameter and injection pressure, are important factors that affect the quality of fuel atomization, air-fuel mixing, and combustion efficiency. An inappropriate combination of parameters can cause suboptimal combustion and increase fuel consumption. This study aims to analyze the effect of variations in nozzle diameter and injection pressure on fuel consumption efficiency in diesel engines. The method used is an experiment with variations in nozzle diameter of 0.150 mm, 0.152 mm, and 0.154 mm and injection pressures of 400 bar, 420 bar, and 440 bar. Tests were conducted at engine speeds of 500 rpm, 1000 rpm, and 1500 rpm with a fuel consumption measurement time of one minute for each parameter combination. Fuel consumption was measured using the volumetric method and analyzed through the fuel volumetric flow rate, fuel mass flow rate, Brake Power (BP), and Brake Specific Fuel Consumption (BSFC). The results showed that the combination of a nozzle diameter of 0.150 mm and an injection pressure of 400 bar produced the lowest BSFC value, thus providing the best fuel consumption efficiency. Meanwhile, the combination of a nozzle diameter of 0.152 mm and an injection pressure of 420 bar showed the closest condition to optimal because it was able to provide a balance between atomization quality and the amount of fuel injected, resulting in efficient and stable combustion. Thus, the efficiency of a diesel engine is influenced by the balance of nozzle size and injection pressure, not solely by the lowest fuel consumption.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that may persist into adulthood and affect academic, social, and occupational functioning. In adult patients, ADHD is frequently associated with an increased risk of Substance Use Disorder (SUD), raising concerns regarding the potential for misuse and dependence related to stimulant medications used in ADHD therapy. This study aimed to evaluate the effectiveness of pharmacotherapy for adult ADHD and to review the risk of stimulant misuse and dependence based on current scientific evidence. The method employed in this study was a literature review using data obtained from national and international journals indexed in Scopus, PubMed, and Google Scholar published between 2017 and 2026. The findings indicated that stimulant medications, such as methylphenidate and amphetamine, were effective in reducing the core symptoms of ADHD by increasing dopamine and norepinephrine activity in the central nervous system. Most studies reported that the use of stimulant medications at therapeutic doses and under medical supervision was not significantly associated with an increased risk of substance misuse or dependence. The risk of misuse was more commonly observed in cases involving non-medical use and inadequate clinical monitoring. In addition to pharmacological therapy, non-pharmacological approaches such as cognitive behavioral therapy (CBT) also contributed to improving treatment outcomes and patients’ quality of life. Therefore, the use of stimulant medications in adult ADHD patients may be considered relatively safe and effective when administered rationally, individually, and under appropriate medical supervision.

Diabetes mellitus is a chronic metabolic disease characterized by elevated blood glucose levels due to impaired insulin secretion, insulin action, or both. Uncontrolled diabetes can lead to various complications and decreased quality of life. Moringa oleifera leaves contain bioactive compounds, including flavonoids, vitamins A, C, and E, as well as selenium, which possess antioxidant properties and are believed to help reduce blood glucose levels. This study aims to determine the effect of Moringa leaf decoction on reducing blood glucose levels in patients with diabetes mellitus in Padaleu Village, Kambu District, Kendari City. The study employs a quantitative pre-experimental design using a one-group pretest-posttest approach. The population consists of 35 diabetes mellitus patients, with 17 respondents selected through purposive sampling. Blood glucose levels are measured before and after the administration of Moringa leaf decoction using a glucometer and observation sheets. Respondents receive 200 ml of Moringa leaf decoction daily for five consecutive days. Data analysis is conducted using paired statistical tests to determine differences in blood glucose levels before and after the intervention. The findings of this study are expected to provide scientific evidence regarding the effectiveness of Moringa leaf decoction as a non-pharmacological therapy for controlling blood glucose levels among diabetes mellitus patients. Furthermore, the results may contribute to nursing science development and serve as a reference for healthcare providers and future researchers in implementing complementary therapies for diabetes management.

Nutritional problems among adolescents are increasingly associated with unhealthy dietary habits and low physical activity, contributing to the rising prevalence of overweight. According to the 2023 Indonesian Health Survey, overweight prevalence among adolescents ranges from 12% to 16.2%. This study aimed to develop Zea Coffee Tab, a functional beverage made from Robusta coffee and corn silk containing bioactive compounds, including caffeine and flavonoids, which may support metabolism and body fat oxidation. An experimental method with a Completely Randomized Design (CRD) was employed. The evaluated parameters included organoleptic tests (hedonic and hedonic quality) involving 30 semi-trained panelists, proximate analysis, and identification of bioactive compounds. Data were analyzed using the Kruskal–Wallis, Mann–Whitney, One-Way ANOVA, and Duncan’s multiple range tests. Three formulations were tested: F1 (30% Robusta coffee:70% corn silk), F2 (50%:50%), and F3 (70%:30%). The findings showed that F3 was the most preferred formulation, with an acceptance score categorized as “very much liked.” The product contained energy ranging from 319.20–324.26 kcal/100 g, protein 5.12–5.34%, fat 0.48–0.58%, carbohydrates 73.85–74.51%, moisture 9.12–9.66%, ash 2.10–2.32%, caffeine 182.45–205.86 mg/100 g, and flavonoids 4.28–6.03 mg/100 g. Zea Coffee Tab has the potential to serve as a healthy functional beverage for overweight adolescents. Further studies on shelf life and clinical effectiveness are recommended to support product commercialization.

Project scheduling is a critical aspect of ensuring the successful implementation of construction projects, particularly bridge projects that involve a high degree of complexity. Poor schedule quality may result in project delays, inaccurate critical path identification, and inadequate project control. This study aims to evaluate the schedule quality of a pile slab bridge project using the Defense Contract Management Agency (DCMA) 14-Point Schedule Assessment method, supported by Oracle Primavera P6 software. The study employed a quantitative descriptive method with a case study approach applied to an existing baseline schedule. The assessment results indicate that several parameters have satisfied the DCMA standards, including relationship type, hard constraints, soft constraints, negative float, large duration, and invalid progress. Conversely, several parameters remain non-compliant with the established standards, namely network logic, positive lag, large float, resources/cost, and the Baseline Execution Index (BEI). This study concludes that the project schedule has not fully adhered to the principles of a network-driven schedule and continues to function primarily as an administrative time schedule. The findings of this study offer practical contributions to construction project management by providing recommendations that encompass the refinement of network logic relationships, reduction of excessive lag usage, implementation of resource and cost loading, and progress updates based on the established baseline, thereby enabling the schedule to serve as a more effective, reliable, and integrated project control tool

The development of digital services by BPJS Ketenagakerjaan through the JMO (Jamsostek Mobile) application has triggered a surge in large-scale and unstructured user reviews on the Google Play Store, thereby complicating manual analysis and conventional sentiment analysis in accurately identifying specific issues. This research aims to implement the Aspect-Based Sentiment Analysis (ABSA) method to granularly evaluate JMO application reviews based on specific aspects, while simultaneously addressing class imbalance and computational efficiency issues. The proposed method combines the pretrained IndoBERT model as a contextual feature extractor, the SMOTE technique to balance the training data, and an artificial neural network (Neural Network) as the classification layer without performing full fine-tuning. The dataset used consists of 90,268 unique reviews categorized into five main aspects through keyword matching, namely General Satisfaction/Complaints, Performance & Stability, Service & Support, Feature Quality, and UI/UX, with initial lexicon-based labeling using the InSet Lexicon. The research results indicate that the proposed model successfully achieves highly optimal performance with an accuracy rate of 91.81% and a weighted F1-score of 92%. Furthermore, the implementation of SMOTE proved effective in enhancing model reliability on the minority class (negative sentiment), achieving an F1-score of 89%. The implications of this research contribute an accurate and efficient aspect-based sentiment analysis framework for developers, and serve as a strategic evaluation tool for BPJS Ketenagakerjaan in mapping specific user complaints to accelerate continuous improvements in the performance, stability, and service quality of the JMO application.

Soft Tissue Tumor (STT) is an abnormal lump or swelling caused by new cell growth originating from connective tissue. Post-operative STT presents major nursing problems including acute pain, knowledge deficit, and risk of infection that require comprehensive nursing care. This scientific paper aims to describe nursing care for Mr. R with post-operative Soft Tissue Tumor (STT) Gluteal Sinistra in Mawar 2 Ward of RSUD dr. Soeselo Tegal Regency. The writing method used is descriptive with a case study plan through interviews, physical examination, observation, and documentation. Assessment was conducted on February 8, 2026 on Mr. R, a 37-year-old male, who underwent left gluteal tumor removal surgery on February 7, 2026. Assessment results identified three nursing diagnoses: acute pain related to physical injury agent (D.0077), knowledge deficit related to lack of information exposure (D.0111), and risk of infection evidenced by invasive procedure effects (D.0142). After nursing interventions for 2x24 hours on February 8–9, 2026, evaluation showed all three nursing diagnoses resolved: pain scale decreased from 6 to 2, the client was able to re-explain the tumor disease, and the surgical wound was clean without signs of infection. The conclusion of this nursing care shows that the application of deep breathing relaxation techniques, health education, and proper wound care are effective in addressing nursing problems in post-operative Soft Tissue Tumor patients.

This study analyzes the implementation of the Central Papua One-Stop Service Information System (Sipersateng) at the Central Papua Provincial Secretariat as a model for administrative innovation in the New Autonomous Region (DOB). The main focus of the study is to explore how a region with extreme infrastructure limitations can leapfrog or institutionalize towards an agile and transparent digital bureaucracy. Using a qualitative descriptive-analytical method with a case study approach, this research involved in-depth interviews, participant observation, and documentation studies to capture the dynamics of the transition from manual to digital systems. The results show that Sipersateng successfully reduced administrative process time by up to 60%. This success was driven by three main dimensions: institutional legitimacy through strong leadership commitment, technical resilience through offline-syncing features to address internet signal fluctuations, and significant changes in work culture. Adaptation strategies such as peer-mentoring methods for senior officials and mandatory policies through gubernatorial instructions proved effective in breaking down organizational cultural resistance. This study concludes that Sipersateng is not merely a technical tool, but rather a manifestation of Frontier Digital Bureaucracy that is able to mitigate the risk of maladministration and build public accountability in the newly formed province. This innovation demonstrates that geographic limitations are not a major barrier to achieving clean governance if supported by inclusive and adaptive system design. These findings provide a theoretical contribution to the public management literature on digitalization in regions with high structural challenges.

Aerobic capacity, commonly measured by maximal oxygen uptake (VO₂max), is a key indicator of physical fitness and athletic performance, particularly in endurance sports. Recent attention has focused on the role of respiratory muscle function in supporting exercise performance, as respiratory muscle fatigue during high-intensity or prolonged activity may reduce ventilatory efficiency and exercise tolerance. This literature review aims to examine current evidence regarding the effects of Respiratory Muscle Training (RMT), including Inspiratory Muscle Training (IMT), on aerobic capacity in athletes. Relevant studies were identified through electronic databases such as PubMed, Scopus, and Google Scholar using keywords related to respiratory muscle training, VO₂max, and athletes. The reviewed studies generally reported improvements in inspiratory muscle strength, reduced respiratory muscle fatigue, and enhanced ventilatory efficiency following RMT interventions. These physiological adaptations may contribute to better exercise tolerance and overall athletic performance. However, evidence regarding direct improvements in VO₂max remains inconsistent across studies. The findings suggest that RMT can be used as a complementary strategy alongside conventional training programs to support aerobic performance. In addition, improved respiratory muscle function may provide benefits in health promotion and rehabilitation by reducing dyspnea and increasing exercise tolerance. Further well-designed studies are needed to clarify the extent of RMT’s contribution to improving VO₂max in athletic populations.

Collaboration between classroom teachers and Islamic Religious Education (PAI) teachers constitutes an essential strategy for instilling religious moderation values in elementary schools. This study aims to: (1) describe the forms of collaboration developed between classroom teachers and PAI teachers; (2) assess the effectiveness of such collaboration in inculcating religious moderation values; (3) identify changes in students' attitudes as tangible outcomes of collaboration; and (4) analyze supporting and inhibiting factors of collaboration at SDN 3 Wanamekar. A descriptive qualitative approach was applied using field study methods. Data were gathered through in-depth interviews, participatory observation, and document review. Data analysis followed the interactive model of Miles, Huberman, and Saldana, encompassing data condensation, data display, and conclusion drawing. Data credibility was ensured through source triangulation and technique triangulation. Findings indicate that collaboration occurs in two primary forms: reactive collaboration as a spontaneous response to students' intolerant behavior, and planned collaboration involving curriculum coordination, partial co-teaching, and joint evaluation. Collaboration was assessed as sufficiently effective yet suboptimal due to time constraints and excessive administrative burdens. Positive changes in students' tolerance and inclusive attitudes were identified as concrete outcomes. Supporting factors include favorable interpersonal communication, principal support, and moderation value integration in the Merdeka Curriculum. Main inhibiting factors are time limitations, administrative burdens, shallow conceptual understanding of religious moderation, and the absence of a standardized collaboration model. The study recommends establishing structured collaboration schedules and religious moderation training programs for all teachers.

One key measure of a region's economic growth is the employment rate, as it reflects the ability of the economy to absorb labor and improve community welfare. In Jambi Province, employment opportunities are influenced by several factors, including Gross Regional Domestic Product (GRDP), population growth, and the Human Development Index (HDI). This study aims to analyze the effects of GRDP, population growth, and HDI on employment growth rates across regencies and cities in Jambi Province. The research employs a quantitative approach using panel data regression analysis covering 11 regencies and cities during the period 2017–2023. The findings indicate that GRDP growth, population growth, and HDI simultaneously influence employment levels. Partially, population growth and HDI have significant effects on employment, indicating that improvements in human development and demographic dynamics contribute to labor absorption. Meanwhile, economic growth, as measured by GRDP, has a relatively small negative effect on employment. This suggests that economic expansion does not always generate proportional employment opportunities, possibly due to structural changes and technological developments. Therefore, policies aimed at improving human capital and labor market conditions are essential to support sustainable employment growth in Jambi Province.

Judicial digital transformation through the implementation of e-Court and e-Litigation represents a strategic initiative of the Supreme Court of Indonesia to establish a modern, effective, and efficient judiciary. These innovations have successfully transformed various stages of civil case administration and litigation into faster and more transparent processes. However, the success of digitalization in case examination has not been accompanied by similar reforms in the execution of court judgments. This study aims to analyze the regulation of civil judgment execution following the implementation of e-Court and e-Litigation, identify challenges encountered in practice, and formulate a concept of execution digitalization as part of judicial reform. This research employs a normative legal method using statutory, conceptual, and case approaches. The legal materials consist of primary legal sources in the form of legislation and Supreme Court regulations, as well as secondary legal sources including scholarly literature and previous studies. The findings reveal that although e-Court and e-Litigation have accelerated dispute resolution processes, the execution of civil judgments remains largely conventional. Consequently, several challenges persist, including delays in execution, lack of transparency, and limited supervision by litigating parties. Therefore, the development of an integrated Digital Execution System linked to existing electronic judicial platforms is necessary to enhance the effectiveness of judgment enforcement and ensure greater legal certainty for justice seekers.

Elderly people are a vulnerable group experiencing declining body functions and an increased risk of degenerative diseases, requiring promotive and preventive efforts to maintain their health. One alternative is the utilization of kitchen spices as herbal drinks because they contain various bioactive compounds that are beneficial for health. However, knowledge among the elderly regarding the benefits and processing methods of herbal ingredients is still limited. This community service activity aimed to improve the knowledge and skills of elderly participants in utilizing kitchen spices as herbal drinks at LKS Payung Besurek Bengkulu City. The method used a participatory approach through educational sessions, interactive discussions, and direct practice in preparing herbal drinks.

Participants were also able to independently prepare herbal drinks using easily available local ingredients. In addition, the activity generated positive social impacts, including improved interaction, increased awareness of healthy lifestyles, and greater independence in maintaining health through natural ingredients. Therefore, this education program is an effective community-based health empowerment strategy for the elderly.

Patient satisfaction with healthcare services remains a major concern in the delivery of healthcare. The behavior of healthcare workers, including friendliness, politeness, and communication skills, plays an important role in improving patient satisfaction. Preliminary data indicated that the number of BPJS patient visits at BLUD UPTD Puskesmas Mokoau had decreased annually, while the results of the patient satisfaction survey were still not optimal because several health programs had not achieved the targeted service standards. This study aimed to analyze the relationship between the quality of healthcare services and BPJS patient satisfaction in the working area of Puskesmas Mokoau in 2025. This research applied a quantitative method with a descriptive-analytic approach using a cross-sectional study design. The study involved 306 respondents selected through a random sampling technique, ensuring that each member of the population had an equal opportunity to be chosen as a research sample. Data were collected using questionnaires and analyzed through the Chi-Square test. The findings revealed significant relationships between facilities, procedures, interaction, and communication with BPJS patient satisfaction, with each variable obtaining a P-value of 0.000 (<0.05). Therefore, the quality of healthcare services is closely associated with the level of patient satisfaction, indicating that healthcare workers need to improve service quality effectively and professionally.

Classical completeness also rose from 65% in cycle I to 86% in cycle II. The use of Canva was proven to stimulate students' creativity and motivation in expressing ideas into aesthetic poetry. The conclusion of this study is that the integration of the PjBL model and Canva media is effective in improving the quality of both the process and the learning outcomes of poetry writing. It is suggested that teachers adopt this model as an innovative alternative for literature learning in the digital era.

Having employees with OCB attitudes will have a positive impact on the ease of achieving organizational goals. OCB is the attitude of employees doing many things outside of their duties voluntarily. In contrast, OCB will influence each other with organizational commitment. Organizational commitment is a person's sense of comfort in being part of the organization. The growth of these two things is influenced by the leadership style, in this case, the transformational leadership style. Based on the preliminary survey results, it has been shown that OCB attitudes and organizational commitment are both influenced by leadership style. So, the researcher wants to see the effect of the three. This study uses multiple linear regression research with quantitative research and a questionnaire with a Likert scale. After the analysis had been conducted, the results were H1: Transformational Leadership had a significant effect on Organizational Citizenship Behavior (OCB) in X Hospital nurses, H2: Transformational Leadership has a substantial impact on organizational commitment in X Hospital nurses, and H3: Organizational Commitment had a significant effect on Organizational Citizenship Behavior (OCB) on nurses at Hospital X.
