Abstract

Coal remains a significant energy source in global and regional economies, particularly in developing countries where reliable energy supply and industrial growth continue to depend on coal availability. However, increasing production capacity requires reliable logistics infrastructure to overcome transportation constraints and operational risks. The Bangun Group’s Tabang Project in East Kalimantan has experienced challenges related to seasonal disruptions in river transportation, which may affect coal delivery continuity and future production expansion. This study aimed to evaluate the financial feasibility and strategic benefits of the Muara Pahu Coal Hauling Road (CHR) and jetty project as a long-term logistics infrastructure investment. A quantitative case study approach was applied using capital budgeting and cost–benefit analysis methods. The assessment utilized secondary data from company reports, project documentation, industry references, and financial assumptions, with evaluation indicators including Net Present Value (NPV), Internal Rate of Return (IRR), Return on Investment (ROI), Payback Period, Benefit–Cost Ratio (BCR), and sensitivity analysis. The results showed that the project generated substantial economic value, with a positive NPV, an IRR exceeding the required rate of return, and a BCR of 3.18, indicating that the project benefits significantly exceeded the investment costs. Sensitivity analysis confirmed the project’s resilience under variations in transportation volume, tariffs, operating costs, and discount rates. Beyond financial performance, the project improved logistics reliability, reduced transportation disruption risks, supported production scalability, and strengthened strategic infrastructure control.

Abstract

Coronary artery bypass grafting (CABG) is a complex cardiac surgical procedure that requires precise anesthetic management to maintain hemodynamic stability and support optimal postoperative recovery. Total intravenous anesthesia (TIVA) has emerged as an alternative anesthetic technique in cardiac surgery due to its advantages in anesthetic titration, hemodynamic control, and facilitation of fast-track recovery protocols. This case report aimed to describe the application of TIVA in a high-risk CABG patient and evaluate its effectiveness in achieving intraoperative stability and early postoperative recovery. A case report was conducted involving a 66-year-old male patient with three-vessel coronary artery disease who underwent CABG at the National Cardiovascular Center Harapan Kita, Jakarta. Clinical data were collected from preoperative assessments, intraoperative anesthesia records, hemodynamic monitoring parameters, and postoperative intensive care management in accordance with the CARE guidelines. The patient received TIVA using propofol, sufentanil, and rocuronium, supported by multimodal monitoring, including the Bispectral Index (BIS), Near-Infrared Spectroscopy (NIRS), arterial line monitoring, and central venous catheter monitoring. The results demonstrated stable intraoperative hemodynamic conditions with appropriate vasoactive support using dobutamine and nitroglycerin. The patient successfully underwent early extubation eight hours after surgery, with acceptable postoperative laboratory parameters and no significant anesthetic complications. In conclusion, TIVA combined with comprehensive hemodynamic monitoring and fast-track protocols provided effective anesthetic management for CABG, supporting cardiovascular stability and early recovery. Further studies involving larger patient populations are required to confirm its broader clinical benefits.

Abstract

This research examines the representation of Nyi Roro Kidul in the character Kadita from the game Mobile Legends: Bang Bang using Roland Barthes' semiotic approach and Stuart Hall's theory of representation. Nyi Roro Kidul, a mythological figure revered by the Javanese people as the ruler of the South Sea, is reimagined as a digital game character. The objects of analysis include verbal signs, all of the character's spoken lines, and visual signs, such as costume, color, attributes, and the visual effects of Kadita's abilities. This research uses a qualitative descriptive method with documentation and direct observation techniques. The analysis applied Barthes' three levels of meaning denotation, connotation, and myth supported by Hall's encoding-decoding theory of representation. The findings show that Kadita's representation of Nyi Roro Kidul is constructed through a synergy of verbal and visual signs that preserve key markers of cultural identity, such as the dominant use of green, the crown, and associations with the sea, while simultaneously undergoing an aesthetic transformation into an anime-style fantasy character defined by active combat. Verbal signs, particularly imperative speech patterns, construct Kadita as a ruler with absolute authority over the ocean, while the myth that emerges reproduces Javanese cosmological beliefs regarding the South Sea as a sacred domain. The study concludes that Kadita represents an adaptive mytha reconstruction of the Nyi Roro Kidul figure shaped to meet the demands of the global digital gaming industry.

Abstract

The Tarakan Electricity System is an isolated electricity system that relies on local power plants and local primary energy supply. Reliance on oil-fired (BBM) plants poses challenges to operational efficiency, while gas supply fluctuations, peak load variations, and plant readiness affect system power adequacy. This study aims to evaluate the role of Liquefied Natural Gas (LNG) regasification in reducing fuel consumption and improving the reliability of the Tarakan Electricity System. The Monte Carlo simulation approach is used because average-based deterministic analysis has not been able to represent operational variability, extreme conditions, and power deficit risk in isolated systems affected by uncertainty of gas supply, peak load, and plant readiness. This study uses Monte Carlo simulations based on actual operational data by comparing two scenarios, namely the baseline scenario without LNG regasification and the intervention scenario with LNG regasification. Stochastic input variables include pipeline gas supply, peak load, PLTD readiness, and PLTMG readiness. The input distribution is based on historical data, while the scenario comparison is carried out using the Common Random Numbers (CRN) principle so that the impact of LNG interventions can be evaluated more objectively. The simulation was carried out as many as 10,000 iterations. Fuel consumption models and power models are able to be validated before being used in scenario analysis.

Abstract

Biomass co-firing in coal-fired power plants is one of the energy transition strategies that enables the utilization of existing power generation assets. This study evaluates the effects of woodchip co-firing on the circulating fluidized bed (CFB) boiler at PLTU Sebalang Unit 1 (2 × 100 MW) using woodchip co-firing ratios of 0%, 10%, 20%, and 30%. The parameters analyzed included gross load, gross and net energy production, fuel consumption across the four coal feeders, total fuel consumption, specific fuel consumption (SFC), gross calorific value (GCV), gross plant heat rate (GPHR), and net plant heat rate (NPHR). The results showed that increasing the woodchip co-firing ratio to 30% did not significantly reduce the gross load, which decreased only from 87.11 MW to 86.94 MW (approximately 0.20%). However, total fuel consumption increased from 267.06 tons to 328.50 tons, while SFC rose from 0.678 kg/kWh to 0.840 kg/kWh. The GPHR increased from 3,044.08 kcal/kWh to 3,448.24 kcal/kWh at a 30% woodchip co-firing ratio, whereas the NPHR increased from 3,369.01 kcal/kWh to 3,830.29 kcal/kWh. These findings suggest that woodchip co-firing can maintain load stability but results in higher fuel consumption and heat rate penalties because of the lower calorific value of woodchips, their potentially higher moisture content, and challenges associated with fuel homogenization and feeding. Therefore, implementing medium- to high-ratio woodchip co-firing requires stringent woodchip quality control, feeder calibration, combustion air optimization, and continuous heat rate monitoring based on actual operating data.

Abstract

A giant aneurysm in the middle cerebral artery (MCA) is a rare condition but has a high risk of rupture, requiring optimal anesthesia planning. This report presents a case of a 33-year-old man with an unruptured giant thrombosed saccular aneurysm in a symptomatic MCA branch since 2018. The patient had undergone several DSA examinations before being planned for craniotomy, aneurysm trapping, and high-flow EC-IC bypass. This report aims to describe the anesthetic management of giant MCA aneurysms undergoing complex surgical procedures to maintain hemodynamic stability and prevent perioperative complications. Physical and neurological examinations were within normal limits, and hemodynamic and laboratory results were stable. Anesthesia management included invasive monitoring, induction using tiopental, remifentanil TCI, and rocuronium, and maintenance of anesthesia with tiopental titration, remifentanil, and low-dose sevoflurane. The surgery lasted 11 hours and 45 minutes, with stable hemodynamic conditions and no intraoperative complications. Postoperatively, the patient was admitted to the ICU with intravenous analgesics. No signs of re-bleeding, hemodynamic instability, or new neurological deficits were observed. The report confirms that anesthesia management in cases of giant MCA aneurysms requires strict control of blood pressure, intracranial pressure, and sympathetic responses during critical phases of induction and extubation. A comprehensive and collaborative approach is essential to prevent complications and support the success of surgery for complex intracranial aneurysms.

Abstract

The healthcare industry in Mojokerto City demonstrates competitive dynamics between public and private hospitals influenced by the tariff regulations of the National Health Insurance (Jaminan Kesehatan Nasional [JKN]). RSUD, as a public hospital, has a cost advantage through government subsidies, creating asymmetric competition with private hospitals such as RS Reksa Waluya. This research aims to analyze the dynamics of asymmetric competition between RSUD XYZ and RS Reksa Waluya and to identify competitive strategies that can support the sustainability of private hospitals. This research employs a managerial economics approach using a comparative case study method involving two hospitals in Mojokerto City to analyze market structure and competitive strategies. The results indicate that the hospital market structure is hybrid, combining characteristics of monopolistic competition and oligopoly. RSUD has an absolute cost advantage, making price-based competition ineffective for RS Reksa Waluya. Competition has shifted from monetary pricing strategies toward non-price factors, such as waiting time efficiency, the adoption of Electronic Medical Records (EMRs), value-based branding, and service specialization, including geriatric care. The sustainability of private hospitals depends more on service differentiation and operational efficiency strategies, while public hospitals should focus on improving managerial efficiency to maintain service quality.

Abstract

Background: Second-degree burns result in significant tissue damage and require optimal management to prevent complications and delayed healing. Silver sulfadiazine (SSD) is widely used as a standard topical therapy for burn wounds. Topical sucralfate has cytoprotective properties and has been suggested to enhance wound healing, making it a promising adjuvant therapy in wound management. Objective: To compare the reduction in second-degree burn wound size following treatment with 10% sucralfate cream, 7% sucralfate cream, and silver sulfadiazine in a rat model Methods: This experimental study employed a post-test only control group design using 48 Sprague Dawley rats with standardized second-degree burn injuries. The subjects were randomly allocated into four groups: Negative control with no treatment (NC), positive control with silver sulfadiazine (PC), treatment group with 7% sucralfate cream (T1), treatment group with 10% sucralfate cream (T2). Wound size was evaluated on days 1, 3, 7, and 14 using digital photographic analysis. Results: A statistically significant difference in wound size reduction was observed among the groups on day 14 (p < 0.001). The 10% sucralfate group (T2) demonstrated the greatest wound reduction, with a mean wound diameter of 44.62 ± 21.43 mm, which was comparable to the silver sulfadiazine group (48.89 ± 10.41 mm). Both groups showed significantly smaller wound sizes compared to the 7% sucralfate group (281.35 ± 99.33 mm) and the negative control group (936.48 ± 159.71 mm). Conclusion: The second-degree burn wound size in the 10% sucralfate group was smaller compared to the 7% sucralfate and silver sulfadiazine groups.

Abstract

In the modern era, the number of social media users continues to increase. Along with technological advancements, consumers no longer make purchasing decisions solely based on product attributes but also consider their digital experiences. Although marketing content and customer reviews are believed to play important roles in influencing purchasing decisions, the extent to which these factors directly affect purchase intention and how this relationship can be explained through the Elaboration Likelihood Model (ELM) theory require further investigation. This study aims to analyze the effects of marketing content effectiveness and customer reviews on purchase intention at D'zuka Restaurant, both partially and simultaneously, and to determine the magnitude of the influence of these variables on consumers’ purchase intentions. This study employed a quantitative research method by analyzing data obtained from questionnaire responses. The results showed that both independent variables had significant effects on purchase intention, with beta coefficients of 0.385 for marketing content effectiveness and 0.474 for customer reviews. Collectively, these two variables explained 61.3% of the variance in purchase intention (R² = 0.613). Both variables indicated information processing tendencies through the central and peripheral routes, with a stronger tendency toward the central route. These findings support the application of the Elaboration Likelihood Model theory in the context of social media and online review-based food marketing, demonstrating that both marketing content effectiveness and customer reviews significantly influence purchase intention, with customer reviews having a slightly stronger effect.
