This research is motivated by the development of injection motorcycle engine management system technology that demands increased performance through optimization of the Electronic Control Unit (ECU). This study aims to analyze the performance comparison of the Yamaha MX King 180 cc using a standard ECU and a racing ECU on engine power and torque. The method used is an experiment with engine dynotest testing in the range of 6000-10000 RPM. The research sample is a 2015 Yamaha MX King unit that has been modified to 180 cc. Data were collected through direct measurements of power (HP) and torque (Nm), then analyzed descriptively in the form of tables and graphs. The results show that the racing ECU is able to produce a higher maximum power of 24.9 HP at 10000 RPM compared to the standard ECU of 22.2 HP at the same engine speed. In terms of torque, both types of ECU reach peak values ​​at 8000 RPM with a relatively small difference (18.18 Nm on the standard ECU and 18.15 Nm on the racing ECU). However, at low to mid-range revs, the racing ECU tends to produce slightly more torque, although at very high revs, it experiences a greater decrease compared to the standard ECU. The racing ECU excels at increasing high-rev power, while the standard ECU exhibits more consistent torque stability. Therefore, the choice of ECU type must be tailored to the performance requirements and the characteristics of the vehicle's use.

Background: Cesarean section (CS) is a mode of delivery frequently used in women with high-risk pregnancies. Over the past two decades, the rate of CS has increased significantly worldwide. Although CS can be a life-saving intervention when performed based on appropriate medical indications, it may also result in adverse outcomes for both mothers and infants and increase the clinical and economic burden on healthcare systems. Limiting CS rates can be achieved through the control of modifiable risk factors. Purpose: This study aimed to describe the factors contributing to the occurrence of cesarean section. Method: This study employed a descriptive cross-sectional design and was conducted at Singasana Regional General Hospital, Tabanan Regency, from February to May 2025. The study sample consisted of 259 women who underwent cesarean delivery during the period 2020–2024. Data were collected through a review of medical records using a checklist instrument. Univariate analysis was performed to describe maternal characteristics and indications for cesarean section. Result: Most cesarean deliveries occurred in women aged 20–35 years (77.99%) and in multiparous women (48.65%). The most dominant maternal factor was a previous cesarean section (37.6%), while the most common fetal factor was fetal distress (42.7%). Conclusion: Maternal age of 20–35 years, multiparity, a history of previous cesarean section, and fetal distress were the dominant factors associated with cesarean delivery. These findings highlight the importance of early antenatal risk screening and optimal labor management to reduce unnecessary cesarean sections and improve maternal and neonatal safety.

Muscle-invasive bladder cancer (MIBC) is an aggressive malignancy associated with high morbidity, reduced survival, and impaired quality of life. Radiotherapy (RT) has been widely used as a bladder-preserving strategy, particularly for patients unsuitable for surgery or systemic chemotherapy. RT may also enhance tumor immunogenicity through programmed death-ligand 1 (PD-L1) upregulation, providing a rationale for combination therapy with immunotherapy. This study aimed to evaluate the effectiveness of combining immunotherapy and radiotherapy in MIBC treatment. A systematic review was conducted following PRISMA 2020 guidelines using the PICO framework. Literature searches were performed in PubMed, Embase, Cochrane, ClinicalTrials.gov, Web of Science, and Scopus databases for studies published between 2016 and 2025. Risk of bias was assessed using the Cochrane Risk of Bias Tool and ROBINS-I. Of 105 identified studies, five met the inclusion criteria and were included in the final analysis. Only one Phase II randomized controlled trial demonstrated low risk of bias in randomization and allocation concealment. ROBINS-I assessment indicated moderate to serious risk in confounding and participant selection domains. Clinical findings showed promising outcomes, with complete response rates ranging from 35%–50% and partial response rates from 25%–40%. Median overall survival ranged from 24–30 months, with favorable disease-free and progression-free survival outcomes. Combined immunotherapy and radiotherapy demonstrate potential to improve survival and disease control in MIBC; however, further rigorous clinical studies are needed to optimize patient-centered treatment strategies.  

This study aims to analyze the effect of financial statement quality and internal control systems on the tax compliance of salted egg MSMEs in Brebes Regency, with business performance as a mediating variable. The research employed a quantitative approach using primary data collected through questionnaires distributed to 150 respondents selected through purposive sampling techniques. Data analysis was conducted using the Partial Least Square-Structural Equation Modeling (PLS-SEM) method. The results indicate that the quality of financial statements has a positive and significant effect on business performance, but a negative and significant effect on MSME tax compliance. Meanwhile, the internal control system does not significantly affect business performance, but has a positive and significant effect on tax compliance. Business performance is also proven to have a positive and significant effect on tax compliance and is able to mediate the effect of financial statement quality. These findings provide an important contribution by showing that high-quality financial statements support business operational management; however, tax assistance and guidance are still needed so that these reports can effectively improve tax compliance.

Circulating tumor DNA (ctDNA) has emerged as a promising liquid biopsy biomarker for real-time monitoring of tumor dynamics. In urothelial carcinoma (UC), effective monitoring of treatment response remains a clinical challenge due to the limitations of conventional imaging and invasive procedures. This systematic review aims to synthesize the existing evidence on the association between ctDNA dynamics and treatment response monitoring across various stages and therapeutic settings. A comprehensive systematic review was conducted. We included cohort studies, randomized controlled trials, and meta-analyses that evaluated ctDNA in UC patients undergoing treatment. Data were extracted on patient population, methodology, treatment, sampling strategy, clinical outcomes, and statistical associations. The review encompassed 80 studies. Baseline ctDNA positivity was strongly prognostic, associated with a 4- to 6-fold increased risk of recurrence or death (HR 4.23-6.56). Dynamic ctDNA clearances or significants reduction during treatment, were strongly associated with improved outcomes. Showing hazard ratios for adverse events as low as 0.10-0.31. ctDNA demonstrated time advantages of 53-90 days over radiographic detection. ctDNA is a potent tool for monitoring treatment response in urothelial carcinoma. It provides superior prognostic and offers a significant lead time for detecting treatment failure. Future research must focus on standardizing methodologies and validating ctDNA-guided therapeutic.

Bankruptcy can no longer be understood solely as a mechanism for liquidating assets to meet debtor obligations, but has evolved into a restructuring instrument that directly impacts corporate governance and stakeholder protection. This study aims to analyze how bankruptcy functions as a corporate restructuring mechanism, how this process influences the redistribution of power in corporate governance, and the extent to which the bankruptcy legal system provides balanced protection for various stakeholders. The research method used is normative legal research with a statutory, conceptual, and limited comparative approach. The analysis is conducted on the provisions of Law Number 37 of 2004 concerning Bankruptcy and PKPU (Investment Suspension) and regulations related to corporate governance, combined with theoretical studies on fiduciary duty, stakeholder theory, and the corporate rescue paradigm. The results illustrate that bankruptcy functions as a governance restructuring mechanism that transfers control from the board of directors to the curator and creditor forum, thereby creating a redistribution of power within the company. The dominant creditor primacy orientation has the potential to create an imbalance in protection for non-creditor stakeholders, including workers and other economically impacted parties. These conditions indicate the need for normative reconstruction, including redefining fiduciary obligations during the insolvency phase, strengthening stakeholder protection, and harmonizing corporate governance principles with the insolvency law regime. This research is expected to contribute academically to the development of a bankruptcy model that is not solely focused on debt resolution but also considers aspects of business sustainability and substantive justice in modern corporate governance.

Dengue fever remains a major global health challenge, particularly in tropical regions, due to the high transmission of Dengue virus by Aedes aegypti and the limited sustainability of current control strategies. Artocarpus odoratissimus, an endemic Bornean plant, contains diverse secondary metabolites with potential pharmacological activities; however, a systematic synthesis of its biomedical relevance to Dengue is still lacking. This study aimed to systematically evaluate the biomedical potential of A. odoratissimus in Dengue prevention and control through a systematic literature review. This study employed a systematic literature review method following the PRISMA 2020 guidelines. Literature searches were conducted in Scopus, ScienceDirect, SpringerLink, PubMed, Google Scholar, Garuda, SINTA, and other relevant scientific databases for publications from January 2016 to February 2026. A total of 303 records were identified, and after duplicate removal, title and abstract screening, and full-text eligibility assessment, 23 studies were included for narrative synthesis. The findings revealed that A. odoratissimus contains major bioactive compounds, including flavonoids, phenolics, arylbenzofurans, stilbenoids, and prenylated chalcones, which demonstrate antioxidant, anti-inflammatory, immunomodulatory, and potential antiviral activities based on in vitro and molecular docking studies. Fruit peel, seeds, and stem bark exhibited the strongest biological evidence, particularly in reducing oxidative stress, inhibiting inflammatory mediators, and potentially interacting with Dengue viral target proteins. Furthermore, several species within the Artocarpus genus showed larvicidal and ovicidal activities against Aedes aegypti, highlighting the potential development of A. odoratissimus as a plant-based biolarvicide candidate.
