Vacuum pressure has a direct influence on increasing the rate of seawater evaporation by lowering the boiling point so that the evaporation process can occur at a low temperature. This study aims to analyze the effect of vacuum pressure on the rate of seawater evaporation for application in a salt pond desalination system. The method used is a literature review from various journals discussing the application of vacuum in the seawater desalination process. The results of the study indicate that reducing pressure significantly accelerates the rate of evaporation and reduces the need for heat energy. The application of vacuum pressure is considered effective in improving performance and efficiency compared to atmospheric pressure systems. This study can provide the development of an energy-efficient desalination system that can be potentially applied in coastal areas.

Improving engine efficiency and stability is a key component of engine technology, especially in the crucial aspect of lubrication to reduce friction and component wear. Conventional lubricants often have difficulty in maintaining thermal stability and tribological properties under high operating conditions. Therefore, the use of nanoparticles in lubricants is being developed as an innovation to improve engine performance. This review aims to analyze the effect of various types and concentrations of nanoparticles on the physical characteristics and performance of lubricants, such as viscosity, thermal conductivity, and the ability to reduce friction. The method used is an experiment in which metal oxide nanoparticles are mixed into the base oil using an ultrasonic method, followed by using a viscometer and tribometer. The findings of this review show that the addition of nanoparticles can significantly improve thermal stability and reduce the coefficient of variation of friction compared to oil without nanoparticle additives. This indicates that nanoparticle-based lubricants have the potential to improve engine and component efficiency.

The evaporation process is strongly influenced by air temperature, particularly the outlet air temperature, which determines the rate of moisture removal and energy efficiency. This literature review analyzes studies on the impact of outlet air temperature on evaporation performance across various applications, including drying systems, cooling towers, and desalination units. Findings from previous research indicate that higher outlet air temperatures generally increase the evaporation rate due to enhanced vapor pressure differences, yet may reduce overall energy efficiency if not properly controlled. Conversely, optimized airflow and moderate temperature gradients promote stable evaporation with lower energy losses. The reviewed literature highlights the importance of balancing thermal and aerodynamic parameters to achieve effective and sustainable evaporation processes. This review aims to provide a theoretical foundation for improving evaporative system design through precise control of outlet air temperature.

Peltier technology uses the thermoelectric effect to transfer heat from one part of the module to another, allowing it to function as a cooler or heater without moving mechanical components. Despite its advantages in terms of reliability and environmental compatibility, Peltier modules still lack energy efficiency compared to traditional cooling systems. Previous research has focused on improving performance through innovations in semiconductor materials, thermal system design, and optimization techniques. In applications to small machines, key challenges include managing the heat on the hot side, incorporating compact designs, and maintaining stable operating temperatures. However, research findings indicate that with appropriate design and material advancements, Peltier modules have the potential to provide efficient and sustainable cooling solutions for low-power machines and portable biomedical devices.

The wheels are one of the main parts of the vehicle. To make car wheels, manufacturers must complete several stages. Especially in the design of the wheels. This study aims to determine the comparative value of three different types of wheels with the same material using aluminum type 6061-T6 (SS). We will test the three-wheel models, namely model 1, model 2, and model 3, with a force of 3000 N and a pressure of 800 N to compare their performance. This test uses Solidworks 2019 software with the finite electronic analysis (FEA) method. The results obtained are the value of Von Misses stress, resulting displacement, equivalent strain and its deformation, and factor of safety. The dimensions of the wheels are 22 inches. The results of the best Model 3 alloy wheel research indicate that the design process is easier. These wheels have a Von Misses stress value of 11.02 MPa with a resulting displacement value of 0.021 mm, an equivalent strain of 0.000096, a safety factor of 25, and a deformation value of 1. Based on these results, model 3 alloy wheels are safe.
