Continuous dedication, professionalism, and transparent procedures are recommended to sustain and improve fleet operational quality.

A crane is a mechanical device used to move loads from one location to another, with gantry cranes being one of the most commonly used types in the industrial sector, particularly at container terminals. While offering numerous benefits, the use of gantry cranes also presents several risks, such as potential structural failure of the crane, falling loads due to damage to hooks or ropes, and collisions with other objects. Additionally, lifting loads beyond the crane’s capacity can lead to equipment damage and even fatal accidents caused by electric shocks or adverse weather conditions like strong winds and rain. This study aims to identify and minimize workplace accident risks by applying the SWIFT (Structured What-If Technique) method. This method identifies hazards through the "what if" approach and evaluates risks using the Risk Rating Number (RRN), which measures the severity and likelihood of potential hazards. The results of this study show that ARTG and STS gantry cranes have 25% of hazards in the priority one category, while RTG has 20% of hazards in the same priority. From these findings, it can be concluded that risk mitigation should be focused on the ARTG and STS types, which show higher risk proportions. The recommendations from this study are to enhance safety procedures, provide continuous training for operators, and conduct regular crane maintenance to reduce the potential for accidents. By implementing these mitigation measures, it is hoped that workplace safety will be maintained and the risk of workplace accidents at the Semarang Container Terminal can be minimized.

Women are an interesting subject of analysis in the media, especially in films. The status of single women, meaning those without a partner, is often accompanied by negative stigma and social pressure to meet societal expectations. This phenomenon is often perceived as a failure to fulfill one's expected role, thereby creating various challenges for single women. This study aims to examine the representation of singlewomen through the character Lainy in the film Kinda Pregnant, exploring how Lainydeals with social stigma and pressure related to her status. Using Stuart Hall's theory of representation, this study applies a descriptive qualitative method and a semiotic approach developed by Roland Barthes. This study analyzes 12 selected scenes to identify relevant themes, such as expectations, reproductive myths, social pressure, and negative stereotypes faced by single women. The analysis reveals that single women are often labeled as “old maids” and compared to the ideal married woman. In this context, Lainy is depicted as struggling against societal expectations regarding marriage and motherhood, while striving to find self-acceptance amid the stigma attached to her status. This study aims to provide insights into the challenges faced by single women in social and cultural contexts, emphasizing the importance of solidarity among women.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in Indonesia’s economy, yet their failure rate remains high due to weak business planning and the absence of systematic feasibility studies. University business incubator laboratories are expected to assist prospective entrepreneurs in conducting comprehensive feasibility analyses, but evaluations are often performed manually and subjectively. This study aims to design a Business Feasibility Information System to support business incubator laboratories in achieving more objective, efficient, and documented assessments. The research employs a Research and Development (R&D) approach using the System Development Life Cycle (SDLC) model, encompassing stages of requirement analysis, system design, and conceptual validation. The system is designed to evaluate four key aspects of business feasibility: market, production, human resources, and finance. The result is a conceptual system prototype that integrates all aspects into a unified assessment framework. The findings indicate that the proposed system enhances the effectiveness of incubator laboratories in evaluating and assisting tenants objectively while fostering digital entrepreneurship literacy. The study implies that information technology integration is essential for strengthening MSME sustainability and decision-making in Indonesia.

Kidney trauma is a relatively common urological injury, often resulting from high-speed motor vehicle accidents, falls, or violent incidents. The kidneys are vulnerable to both blunt and penetrating trauma, with blunt mechanisms accounting for approximately 90% of all renal injuries. This paper reviews the anatomy of the kidney, mechanisms of injury, classification according to the American Association for the Surgery of Trauma (AAST), diagnostic evaluation, imaging modalities, and current management strategies. Most renal traumas are managed conservatively based on hemodynamic stability, while surgical exploration is indicated in severe or vascular injuries. Understanding the mechanism of injury and applying appropriate diagnostic evaluations are essential to determine the correct management approach and improve patient outcomes. Moreover, advancements in imaging techniques, such as CT scans, have significantly improved the accuracy of diagnosing renal injuries. Early intervention and appropriate monitoring are crucial in preventing complications such as hemorrhage or renal failure. This review aims to provide a comprehensive overview of renal trauma management to aid clinicians in improving patient care and optimizing recovery.

The manufacturing industry in Indonesia has experienced significant growth. This increase has also impacted the demand for motorcycle spare parts. Currently, brake pads are composed of asbestos, which makes them prone to overheating and failure when reaching high friction temperatures. Therefore, an alternative brake pad material is an organic material mixed with coconut shell powder and bamboo fiber. This study aims to analyze the wear and hardness levels of motorcycle brake pads made from coconut shell powder and bamboo fiber. The study used varying ratios of coconut shell powder, bamboo fiber, and epoxy resin: 40:30:30, 35:35:30, and 30:40:30. Eighteen specimens were tested. Wear testing was performed using an Ogoshi Wear Tester, while hardness testing was performed using a Brinell hardness tester. The test results showed that the smallest wear rate on brake pads with variations of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin was 0.001107984 mm3/kg.m. The highest hardness level was also in the variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin at 63,0024 kg/. So it can be concluded that the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the lower the wear rate. If the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the higher the hardness level. So it can be concluded that a good brake pad variation is a variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin.

Drug stock-outs are an indicator of pharmaceutical management failure that directly affects patient safety and the quality of hospital services. Gatoel Hospital Mojokerto experienced an increase in the percentage of drug debt from 3.14% in January to 6.20% in July 2025, with 1,607 patients affected. This study aims to identify the factors causing drug stock-outs and formulate preventive strategies through the optimization of the Minimum-Maximum Stock Level (MMSL) system based on the Hospital Information System. A mixed-method approach was used, combining secondary data analysis (January–July 2025) and in-depth interviews. Fishbone analysis was applied to identify root causes, USG analysis to determine priorities, and SWOT analysis to formulate intervention strategies. Priority drug classification was carried out using the ABC-VEN method. The intervention involved implementing an MMSL pilot project for 150 drug items under Pareto category A. The analysis identified six dimensions of stock-out causes: man, materials, methods, machines, measurement, and environment. The highest priority issue was drug demand forecasting based on historical data (USG score: 125). SWOT analysis placed the organization in quadrant II, recommending a Weakness-Opportunities (WO) strategy. MMSL implementation was initiated through the development of SOPs and the entry of 150 priority drug items into the system. Drug stock-outs are caused by multifactorial issues that require systemic intervention. MMSL optimization has the potential to serve as a long-term solution, provided there is expanded coverage, strengthened human resource capacity, and comprehensive system integration.

The braking system was a crucial component in ensuring the safety of motor vehicles on the road. Brake failures, such as brake fade or total malfunction, could result in fatal accidents. Therefore, an accurate and realistic testing method was necessary to measure the effectiveness of a vehicle’s braking system. This study aimed to develop a deceleration measuring device based on GPS, which could be used in road test methods. The device was designed using an ESP32 microcontroller combined with a BN-220 GPS module, RTC real-time clock sensor, 16x2 LCD, thermal printer, and microSD storage media. Testing was conducted on a Mitsubishi L300 vehicle at the Depok Beach runway in Yogyakarta, with initial speed variations ranging from 10 to 80 km/h. Calibration results showed that the device had an accuracy of 99.64% with an average error of 0.36%. Meanwhile, the test results recorded deceleration values ranging from 0.74 to 3.26 m/s², depending on the initial speed and braking conditions. Based on these findings, the developed device proved to be accurate and feasible as an alternative method for field testing of braking systems.

Enhancing the efficiency of renewable energy on ships is crucial for reducing dependency on fossil fuels. This research employs the Research and Development (R&D) method, aiming to design and implement a solar panel optimization system for battery charging, with a focus on increasing power efficiency and providing real-time performance monitoring. The system is designed using Maximum Power Point Tracking (MPPT) technology to maximize the solar panel's power output. A 200Wp solar panel with dimensions of 1290 x 760 x 30 mm was utilized. Static testing results show that the deployed sensors possess a high degree of accuracy, with an average error of 0.71% for the temperature sensor and only 1.81% for the light sensor used to monitor environmental conditions. Dynamic and system integration tests prove that the MPPT implementation significantly increases power output efficiency by 30.83% compared to a system without MPPT. Furthermore, the system with MPPT charges the battery approximately 27% faster. Additionally, the developed Modbus protocol-based monitoring system enables comprehensive and remote monitoring of key parameters such as voltage, current, temperature, and light intensity via a cloud database. Data communication reliability tests confirmed the system's capability to transmit entire data packets to a Google Sheets database at a periodic interval of 15 seconds without failure. Based on these results, the developed solar panel optimization system is feasible for implementation in maritime environments to enhance the utilization efficiency of renewable energy and the operational reliability of onboard systems.

Public service innovation across various levels of government represents a positive sign of progress in Indonesia’s bureaucratic reform efforts. In practice, however, it is essential to ensure that such innovations genuinely enhance the public value of existing services so that they effectively address the needs of service recipients. Field evidence indicates that the implementation of public service innovations continues to face multiple challenges. The public value generated by an innovation may vary—or even fail—when viewed from the perspectives of different stakeholder groups. This study examines these dilemmas, an area that remains relatively underexplored. Employing a qualitative approach that includes in-depth interviews, observation, and a review of relevant literature, the research finds that failures in public value often arise from inherent dilemmas within public service innovation itself. Accordingly, government administrators are expected to develop a clear understanding of the values that should be embedded in the public service innovations they implement. Furthermore, attention must be paid to variations in social conditions and local cultures, as enhancing public value requires alignment between the values underpinning innovation and the cultural context of the community it serves. Finally, public sector organizations, as the primary agents of practical implementation, must provide legitimate mechanisms to reconcile value conflicts when they arise.  

This study examines the application of the Piercing the Corporate Veil doctrine in cases of fiduciary duty violations by the President Director of PT Bakara Bumi Energi, based on the Jakarta Central District Court Decision No. 451/Pdt.P/2019/PN.JKT.Pst. Using a normative juridical approach, the research analyzes primary and secondary legal sources, including Law No. 40 of 2007 on Limited Liability Companies and relevant court rulings. The findings reveal that the President Director's failure to provide transparent financial reports and operational information constitutes a breach of fiduciary duty, encompassing duties of loyalty and care, leading to financial losses such as tax arrears and reputational damage. Furthermore, this breach justifies the application of the Piercing the Corporate Veil doctrine to hold the director personally liable, as supported by similar judicial precedents. The study concludes that enforcing this doctrine enhances corporate governance and accountability, recommending clearer regulatory frameworks for broader application to directors and other corporate organs.

The increasing integration and digitization of smart grid systems have exposed them to a variety of security threats, necessitating robust security measures to ensure their reliability and efficiency. This paper proposes a novel Digital Twin-Based Cyber-Physical Security Framework, incorporating AI-driven predictive maintenance and zero-trust architecture to address the evolving challenges of securing smart grids. By leveraging digital twin technology, this framework creates a real-time virtual representation of physical systems, enabling continuous monitoring and simulation for enhanced security and operational performance. Zero-trust security principles are integrated to ensure that no entity, whether inside or outside the network, is trusted by default, thus significantly reducing the risk of cyber-attacks. Additionally, AI-driven predictive maintenance enhances the framework’s reliability by proactively identifying potential failures before they occur, reducing downtime and improving system resilience. Through the development and simulation of this framework, including attack and failure scenarios, the paper demonstrates that the proposed system outperforms traditional methods in terms of anomaly detection, system downtime, and response times. The integration of predictive maintenance allows for early identification of component failures, thus enhancing the overall resilience of the grid. The zero-trust architecture further strengthens the cybersecurity posture, preventing unauthorized access and attacks. The study also identifies challenges, such as data synchronization and scalability, which must be addressed for broader implementation in large-scale smart grid systems. The findings suggest that the proposed framework could play a critical role in the future evolution of smart grid security, offering valuable insights for researchers and practitioners.  

This research aims to comprehensively describe and understand the utilization of the SINKARKES system (Ship and Health Information System) in the issuance of the Ship Sanitation Control Exemption Certificate (SSCEC) and the First Aid for Accidents (P3K) Certificate for vessels managed by PT. Surya Samudera Indah Batam. Compliance with ship sanitation and health standards is a mandatory prerequisite for preventing disease spread and ensuring occupational safety in accordance with prevailing regulations. The research methodology employed is field research (field research) to observe direct operational procedures in the field, supplemented by literature review (library research) to strengthen the theoretical and regulatory foundations of the Ministry of Health. The findings indicate that the process of issuing the certificates through SINKARKES begins with agent login access to the official application (sinakarkes.kemkes.go.id) using a registered company account. Subsequently, the agent submits an application for SSCEC and P3K issuance, followed by the completion of data and the uploading of mandatory supporting documents. These documents include the Maritime Health Declaration (MDH), previous SSCC/SSCEC certificates, the P3K certificate, crew list, voyage memo, and the list of last ports of call. Once the documents are verified, the Special Health Quarantine Officer (KarKessus) proceeds to conduct a physical survey onboard the vessel. The main obstacle encountered is poor internet network connectivity in the port area, which often leads to data input failures and double entry errors during certificate printing.

This study examines the application of Educational Data Mining (EDM) to predict the academic per-formance of first-year students at the Catholic University of Bukavu and the Higher Institute of Edu-cation (ISP) in the Democratic Republic of Congo. The primary objective is to develop a model that can identify at-risk students early, providing the university with a tool to enhance student support and academic guidance. To address the challenges posed by data imbalance (where successful cases outnumber failures), the study adopts a hybrid methodological approach. First, the SMOTE algorithm was applied to balance the dataset. Then, a stacking classification model was developed to combine the predictive power of multiple algorithms. The variables used for prediction include the National Exam score (PEx), the secondary school track (Humanities), and the type of prior institution (public, private, or religious-affiliated schools), as well as age and sex. The results demonstrate that this approach is highly effective. The model is not only capable of predicting success or failure but also of forecasting students' performance levels (e.g., honors or distinctions). Moreover, the use of the Apriori association rule mining algorithm allowed the identification of faculty-specific success profiles, transforming prediction into an interpretable decision-support tool. This research makes several significant contributions. Practically, it provides the University of Bukavu with a tool for student orientation and early risk detection. Methodologically, it illustrates the effectiveness of a combined approach to EDM in an African context. However, the study acknowledges certain limitations, including the non-public nature of the data and the geographical specificity of the sample. It therefore proposes avenues for future research, such as the integration of Explainable AI (XAI) techniques for more refined and transparent analysis of the results.

This article employs a Critical Literature Review (CLR) approach, analyzing studies from 2013–2025 that include academic papers, nationally accredited journals (Sinta 2–4), and reputable international journals indexed by Scopus (Q1–Q4) to understand systemic fraud and audit failure in Indonesia.Previous re-search has mostly explained fraud from individual or organizational views, while few have addressed structural factors such as the normalization of fraud, weak regulatory oversight, and the crisis of auditor legitimacy. The synthesis reveals four main issues. First, systemic fraud in Indonesia has shifted from in-dividual misconduct to a structured socio-economic phenomenon rooted in culture. Second, auditing as a control mechanism remains technically focused, often failing to uncover collusive fraud involving top management. Third, an expectation gap exists between unqualified audit opinions and public demands for assurance against corruption, reducing trust in auditors. Fourth, conflicts of interest arising from audit fee dependence, weak regulation, and limited adoption of audit technology and forensic analytics indicate the need for institutional reform. Therefore, this article calls for an integrative framework that connects individual, organizational, regulatory, and socio-cultural dimensions to address systemic fraud and rein-force public accountability in Indonesia.

Hypertension is one of the most common non-communicable diseases, with a high incidence rate that has become a major global health concern. It is often referred to as a “silent killer” because many patients are unaware of their condition until serious complications arise. In Indonesia, the prevalence of hypertension is relatively high, yet many sufferers remain undiagnosed or do not receive proper medical treatment. Several risk factors contribute to hypertension, including age, heredity, high-salt diet, obesity, lack of physical activity, and unhealthy lifestyles such as smoking and alcohol consumption. Without proper management, hypertension may lead to severe complications such as stroke, heart failure, and chronic kidney disease. Management of hypertension generally involves pharmacological therapy, such as the administration of antihypertensive drugs, as well as non-pharmacological interventions through lifestyle modifications. Nurses play a crucial role in patient education, monitoring, and preventing complications through comprehensive nursing care. The purpose of this study is to describe the nursing care provided to Mr. R, who experienced a cardiovascular system disorder, namely hypertension, in the Dahlia Ward of RSUD dr. Soeselo, Tegal Regency. The research method used was descriptive with a case study approach, allowing for a systematic and clear presentation of the patient’s condition. The case findings showed that the patient’s main complaint was a headache radiating to the nape of the neck. Based on nursing assessment, two nursing diagnoses were identified: acute pain and lack of knowledge regarding the disease and its management. Interventions were determined using national standards such as SDKI, SLKI, and SIKI, which are expected to reduce symptoms and improve the patient’s understanding of hypertension.

This article examines the legal consequences of a delayed notification of a share acquisition under Indonesian competition law, focusing on the case of PT X's takeover of PT Y. The central issue is PT X's failure to report the acquisition to the Commission for the Supervision of Business Competition (KPPU) within the mandated 30-day period, as stipulated by Law Number 5 of 1999 and its implementing regulation, Government Regulation Number 57 of 2010. The notification was submitted with a significant delay of 2,023 days, a clear violation of the statutory requirements. As a result of this non-compliance, the KPPU, through its Decision No. 31/KPPU-M/2020, imposed an administrative fine on PT X amounting to   IDR 1,050,000,000.00 (one billion fifty million rupiah). Beyond the direct financial penalty, the violation led to severe indirect repercussions, including significant    reputational damage, which threatened to erode investor confidence and disrupt existing business relationships. The KPPU's firm and consistent enforcement in this case highlights the critical function of the post-merger notification system in Indonesia as a preventative mechanism to assess transactions that could lead to excessive market concentration. The decision underscores the legal principles of     transparency, fairness, and accountability that underpin Indonesian competition law. This case serves as a powerful deterrent, signaling to all business actors that non-compliance will not be tolerated. Ultimately, such rigorous enforcement is crucial for fostering a culture of legal adherence, maintaining market integrity, and building a more transparent and competitive business ecosystem that supports sustainable economic growth in Indonesia.

The 2021 Indonesian Nutritional Status Survey (SSGI) shows that 1 in 4 Indonesian children suffers from stunting and 1 in 10 children suffers from malnutrition. Good nutrition is a crucial foundation for optimal growth and development, especially for those growing up in vulnerable environments. According to the WHO, stunting is a failure of growth and development experienced by children due to prolonged inadequate nutritional intake, recurrent infectious diseases, and inadequate psychosocial stimulation. However, on the other hand, children who experience stunting are usually accompanied by developmental delays in various other organs, especially if malnutrition occurs during the first 1000 days of life (HPK). Stunting is defined as a child's length for age (PB/A) or height for age (H/A) that is lower than -2 standard deviations. Therefore, a child with stunting is definitely stunted, but a child who is stunted is not necessarily stunted. Stunting that occurs before a child is 2 years old is an indication of decreased cognitive abilities at a later age if not followed by adequate psychosocial stimulation, thus impacting academic or educational abilities later in life. Providing innovative education such as making moringa pudding is one way to present nutritious and creative food or drinks so that it can be accepted by kindergarten mothers who have toddlers and preschoolers. The content of moringa leaves is a food ingredient that has good nutritional value, especially for preventing stunting in children.

Indonesia is a country with high lightning strike intensity, making lightning protection systems critically important, especially for public infrastructure such as Light Rail Transit (LRT). This research aims to analyze the lightning protection system implemented in the Jakarta LRT Phase 1B Project, particularly in the station areas and railway lines. The methods used include field observation, literature study, interviews, and technical analysis using the rolling sphere method, protective angle method, and mesh method to determine the coverage of protected areas. In addition, an evaluation of the grounding system was conducted to ensure the safe discharge of lightning currents into the earth. The analysis results show that the lightning protection system applied complies with PUIPP and IEC 62305-1 standards and is capable of protecting signaling and telecommunication equipment from lightning risks. The combination of the three protection methods provides comprehensive coverage for LRT structures. The grounding system design also meets the standard resistance requirement (< 5 Ohms), ensuring operational safety and protecting critical equipment. Furthermore, the study highlights the importance of integrating lightning protection with other safety systems such as fire protection and electrical surge protection, as lightning can cause cascading failures that disrupt railway operations. Proper maintenance and periodic testing of grounding resistance are also necessary to ensure long-term reliability. In addition, the Faraday cage principle applied to train cars contributes to passenger safety by preventing lightning currents from penetrating the cabin interior. This research is expected to serve as a reference for developing lightning protection systems in similar infrastructure projects, especially in regions with high lightning density. By applying international standards and comprehensive protection methods, the Jakarta LRT demonstrates how modern urban transportation can operate safely despite extreme weather risks.
