Abstract

This study examined the role of self-efficacy and peer social support in problem-focused coping among Chief Engineers (Kadepsin) of Navy Warships (KRI) in the Eastern Fleet Command (Koarmada II). The maritime work environment posed various challenges, requiring effective coping strategies. Self-efficacy, defined as an individual’s belief in their ability to overcome difficulties, and peer social support, including emotional and instrumental assistance, were assumed to contribute to managing work-related stress. A quantitative approach was employed, using a saturated sampling technique involving 72 Chief Engineers as respondents. Data were collected via Google Forms using validated scales: a 16-item self-efficacy scale (α = 0.898), a 21-item peer social support scale (α = 0.905), and a problem-focused coping scale (α = 0.940). The results showed that self-efficacy and peer social support significantly predicted problem-focused coping (R² = 0.915), accounting for 91.5% of the variance. Minor hypothesis tests revealed that self-efficacy contributed 84.6% and peer social support contributed 87.2% to problem-focused coping. These findings highlighted the importance of enhancing self-efficacy and social support networks to improve coping strategies in high-pressure maritime work environments.

Abstract

Heat transfer in turbulent flows is one of the essential topics in power plants and thermal-based engineering. This study aims to analyze the effects of density changes due to heat transfer in a turbulent environment—which is usually neglected because it can cause instability in a simulation. We simulate an available experimental case of turbulent heat transfer of air with OpenFOAM: one with an incompressible approach (no density change) and another with a compressible treatment. The simulation geometry is a 0.75 × 0.75 m2 square cavity, where its left and right walls are kept at a temperature difference of 40 K. We compare and analyze the temperature, velocity, and turbulence kinetic energy profiles of both simulation results against the experimental data. We found that from all qualitative and quantitative comparisons, the change in density plays a vital role in turbulent heat transfer. The compressible treatment gives better results than the incompressible: the neglection of density change causes a significant difference with the experimental data. Thus, we strongly recommended incorporating compressibility in simulating heat transfer in turbulent flows.
