Abstract

This paper develops a Weibull-based reliability model for the Integrated Drive Generator (IDG) installed on Boeing 737-900ER aircraft operated in Indonesian low-cost carrier conditions. Time-to-removal is modeled on a Flight Hours (FH) exposure scale and explicitly incorporates right-censored observations using Maximum Likelihood Estimation (MLE). The estimated Weibull shape parameter (?= 3.308 and ? = 7261 FH) indicates a wear-out dominated failure pattern typical of rotating machinery degradation. An age-replacement cost model is then formulated to minimize expected cost rate (USD per FH) by trading planned preventive cost, unplanned corrective cost, and downtime penalties. The Mean Time to Failure (MTTF) is approximately 6514 FH. Cost optimization results suggest an optimal preventive replacement interval in the range of 4750-6650 FH, with a baseline recommendation of approximately 5450 FH. A sensitivity analysis across representative cost scenarios demonstrates how the optimal preventive maintenance interval shifts when operational disruption costs increase. The proposed workflow provides a practically implementable template for maintenance planning of removal-driven line replaceable units under high utilization.

Abstract

The optimization of Key Performance Indicators (KPIs) in steam turbine power plants is crucial for enhancing operational efficiency in the palm oil processing industry. This study applies the Analytic Hierarchy Process (AHP) to determine the relative weights of KPIs, thereby supporting data-driven decision making for performance improvement. Four critical KPIs were evaluated through pairwise comparisons expertise. A Python based computational model was developed to automate AHP calculations, ensuring accuracy and efficiency in deriving priority weights. This study reveals power output (47.16%) is the most significant KPI, followed by availability factor (38.58%), steam consumption (9.69%), and capacity factor (4.58%). The consistency ratio (CR) for all expert judgments was below 0.10, validating the reliability of the AHP outcomes. This research demonstrates that integrating AHP with Python programming provides a robust framework for KPI prioritization. The findings offer practical insights for industry stakeholders to optimize steam turbine performance and reduce operational inefficiencies.

Abstract

Global climate change is closely related to increasing greenhouse gas emissions, including those generated by energy-intensive refrigeration systems on fishing vessels. Conventional onboard cooling systems often operate at relatively low efficiency, resulting in high fuel consumption and environmental impact. This study aims to analyze the coefficient of performance (COP) of a cascade refrigeration system with a flash chamber for fishing vessel applications by evaluating the influence of refrigerant selection and intermediate operating temperature. A steady-state thermodynamic simulation model was developed using Engineering Equation Solver (EES). Three refrigerants, namely R134a, R404A, and R407C, were investigated under intermediate temperature variations of 10–30 °C. The model was validated through comparison with reference data from the literature. Simulation results include compressor power consumption, condenser heat rejection, evaporator heat absorption, and COP values. The results indicate that intermediate temperature significantly affects compressor work distribution between the low-stage and high-stage compressors. Among the evaluated refrigerants, R134a achieved the highest COP under all operating conditions, while R404A showed lower condenser heat rejection and cooling capacity. Overall, the cascade refrigeration system with a flash chamber demonstrates improved energy performance and offers a promising solution to reduce fuel consumption and greenhouse gas emissions in marine refrigeration applications.

Abstract

Friction welding of aluminum and copper is a solid-state joining technique widely used in electrical and industrial applications. Significant differences in physical and thermal properties between these metals create challenges at the joint interface. This review focuses on the metallurgical characterization of Al–Cu friction welded joints, emphasizing intermetallic compound (IMC) formation and growth, and the influence of process parameters such as temperature, pressure, friction time, and rotational speed on microstructure and mechanical performance. Excessive IMC layers can cause embrittlement, interfacial cracking, porosity, and reduced thermal stability. Recent advances in process optimization, active cooling, and interface engineering have improved joint strength, ductility, and conductivity. Controlling IMC growth and understanding intermetallic diffusion are crucial for producing reliable Al-Cu joints. This review summarizes current strategies for enhancing the mechanical performance of Al–Cu friction welded joints.

Abstract

This study investigates the dynamic response of a commuter aircraft windshield subjected to drone impact and compares its damage characteristics with bird-strike conditions. Numerical simulations were conducted using the finite element method (FEM), incorporating variations in impact location, angle, and velocity. The results show that both impact location and angle significantly affect damage severity. For location and angle variations, the drone penetrated the windshield, with the most severe damage occurring at the center location and a 0° impact angle, resulting in maximum energy absorption of 1573.98 J. The plastic strain area at the center and at 0° was wider than at the upper edge and 22.5°, respectively. For velocity variations, the highest absorbed energy of 1975.04 J occurred at 105.5 m/s. At 58 m/s, cracking occurred without penetration, while penetration occurred at 80 m/s and above. Despite its lower mass compared to a 910 g bird, the drone impact proved more hazardous due to windshield penetration.

Abstract

The bolts used to retainer and fasten the shaft of the screw conveyor, which functions to transport wood chips to the cooking process in paper manufacturing, have experienced failure. The failure occurred in the form of a perpendicular fracture on the threaded section of the bolt. This damage significantly disrupts wood processing operations, making it important to investigate the causes. The causes of bolt fracture and its short service life were analyzed by studying the effect of thread pitch variations of 2.5 mm and 2 mm. The material tested was Valmet (VME), which is equivalent to AISI 4140. The fatigue test was conducted using a cantilever rotating bending method with the test specimens according to ASTM E466M standards. The results showed that to achieve infinite life, the stress level must be below 95 MPa. Thread pitch has a significant effect: VME bolts with a thread pitch of 2 mm showed a 17% longer endurance than bolts pitch of 2.5 mm.

Abstract

Optimizing fishing vessel hull design is crucial for improving energy efficiency and meeting stringent environmental regulations. This study investigates the hydrodynamic resistance of a fishing vessel equipped with a dihedral bulbous bow and retractable bow foils, NACA 0015 and NACA 2408. Computational Fluid Dynamics (CFD) simulations based on Reynolds-Averaged Navier-Stokes (RANS) equations were conducted in calm water conditions. Contrary to the targeted resistance reduction, the baseline hull without foils exhibited the lowest total resistance across all tested velocities, recording 9.78 N at 1,286 m/s. Integrating the retractable foils increased total resistance by 27.48% (NACA 0015) and 15.23% (NACA 2408). This resistance penalty stems from an expanded wetted surface area amplifying frictional resistance, combined with interference resistance that disrupts the bulbous bow's streamline flow. Ultimately, the objective of a ?10% resistance reduction was unachieved, establishing the unmodified baseline hull as the most hydro-dynamically efficient configuration.

Abstract

The utilization of industrial waste as an alternative energy source, such as Palm Oil Mill Effluent (POME), represents a promising approach, as it has a high potential to be converted into energy while simultaneously reducing environmental pollution. This research aims to achieve a steady state condition, so that it can be operated continuously using a pilot scale acidogenesis phase anaerobic hybrid bioreactor with a capacity of 12.5 L. This study employed a 12.5 L laboratory reactor operated at a controlled 24-hour Hydraulic Retention Time (HRT) to realistically represent the interactions and operating conditions commonly encountered in practical environmental systems. The results of the study showed that the seeding and acclimatization process lasted for 16 days and the start-up stage lasted for 71 days until the steady state of anaerobic hybrid bioreactor was achieved with pH conditions of 7. The Chemical Oxygen Demand (COD) loading rate was 2,240 mg/L-hour, COD concentration of 3,750 mg/L, alkalinity concentration of 1,920 mg/L, the Volatile Fatty Acids (VFA) concentration of 589 mg/L. The Total Solids (TS) concentration was 30,800mg/L and Total Suspended Solids (TSS) concentration of 9,400mg/L. The Total Volatile Solids (TVS) concentration was 24,100mg/L, the Volatile Suspended Solids (VSS) concentration of 3,100mg/L and biogas production of 1.8 L/hour. The steady state of the acidogenesis phase anaerobic hybrid bioreactor with a hydraulic retention time of 1 day can obtain a COD removal efficiency of 93.3% with a VFA/Alkalinity ratio of 0.3.

Abstract

The management of environmental factors such as temperature, humidity, and ammonia levels are critical to the health and productivity of broiler chickens. Yet, many farmers still rely on manual monitoring, which is inefficient and prone to human error. Therefore, adopting the IoT-based telemetry systems can enhance monitoring accuracy and efficiency in poultry farming. This article evaluates the effectiveness of Internet of Things (IoT)-based telemetry systems in automating and monitoring poultry environments. By integrating various microcontrollers such as Arduino, NodeMCU ESP32 and Wemos D1 Mini with advanced sensors (DHT11/22, MQ-13 and ultrasonic sensors), these systems provide real-time data visualisation and automatic actuator control. Research methods include the waterfall development model, which involves prototyping models, utilising control logics like threshold, fuzzy tsukamoto, and Gaussian Naive Bayes. Results indicate the IoT implementation can maintain the coop's microclimate within ideal ranges (28°C–34°C for temperature), reduce energy consumption by up to 25%, and significantly lower mortality rates by maintaining ammonia levels below 20 ppm. The integration of telemetry via web dashboards, Blynk, and Telegram allows farmers to monitor and control their livestock remotely, enhancing operational efficiency and productivity.
