Abstract

Cloud Kitchen is a commercial kitchen that serves food for delivery or takeaway without dine-in customers. Because the cloud kitchen consists of many kitchens, good air circulation is needed. The total volume of the 15 kitchen units in the cloud kitchen is 249.8 m3, so to meet commercial kitchen standards that have a minimum Air Change per Hour (ACH) value of 30 ACH, an air change of 4410 m3/h with a ducting system is required. From the simulation results, the air velocity distribution in the ducting ranges from 0 m/s to 92.426 m/s, while the pressure distribution in the ducting ranges from -578.824 Pa to 11639.58 Pa, and the distribution of air temperature in the ducting ranges from 49.8°C to 65.167°C. The chosen exhaust fan is a CKE brand centrifugal fan with type CKE DGB-4.5#-NO and an exhaust capacity of 5712–10562 m3/h.

Abstract

The need for clean water in household life is very important because humans cannot live without it. The composition of seawater consists of 96.5% pure water and 3.5% other materials, namely salts, dissolved gases, and others. Indonesia is one of the countries that has the second-longest coastline in the world, so the potential for utilizing sea water is very large, one of which can be through the desalination process. Distillation itself is distillation, and its by-product is salt when seawater is heated using a heat energy source with a concentrated solar power (CSP) system. Based on research that has been done previously, the tool is a lab-scale seawater desalination device, but the process of making a lab-scale seawater desalination tool is not optimal. Then design the construction of a lab-scale seawater desalination device with the Multi Stage Flash (MSF) type, and the aim is to determine the performance and functionality of the MSF-type lab-scale seawater desalination device. The results show that the results of the coil heat exchanger development obtained an inlet temperature of 85.9°C and an outlet temperature of 67.8°C, and the room temperature in the chamber can be maintained at a temperature of 68.9°C. As for the components being developed, such as sea water pumps, hoses, tees, and sprayers, a sea water debit of 53.78 liters per hour has been obtained.

Abstract

The CC-201-type U18C locomotives are widely used for public transportation in Indonesia. Like other modes of transportation or vehicles, the body's design is an important factor to consider because it influences the aerodynamic capabilities of the vehicle. The study aims to analyze the effect of variations in the design angle of the CC-201 type U18C locomotive body on the coefficient of drag and aerodynamics. The method used in this research is CFD simulation using CAE-based engineering software, Ansys Fluent R2 2022. CFD simulations were performed on locomotive body designs with angle variations of 90°, 135°, and 150° using the same boundary condition parameters. The results show that the locomotive body design with the 60° variation has the smallest drag coefficient value of 0.51076379. The study conclusion explains that changing the angle of 150 degrees at the top of the GE U18C-type locomotive body has a significant effect on lowering the value of the drag coefficient by up to 29%.

Abstract

This research was carried out because it is known that there are six potential work accidents that can occur production departments of PT. XYZ. PT XYZ, so it is necessary to identify employee safety risks to obtain the right solution to prevent the occurrence of work accidents, and the method chosen is failure mode and effect analysis. FMEA is a table-shaped identification tool that is useful for identifying errors, evaluating the effects of errors, and prioritizing errors. Data collection is carried out through observations, interviews, and discussions with employees in production departments of PT. XYZ. Accidents that are the main priority to resolve first are milling machine operators injured due to exposure to grams of iron that can result in delayed operator work because the accident has the largest RPN value of 210, with details of severity 6, occurrence 7, and detection 5. The conclusion of this study is that PT. XYZ, which does not provide self-protection equipment for workers in the production department, is the most prevalent cause of work accidents, so more attention should be paid to the procurement of protective equipment and requiring workers to wear it.

Abstract

The tank car is a closed storage area or tank designed to contain the liquid as a gas or liquid at a different pressure than the ambient pressure. Chemical reactions with the fluid inside a car's tank or physical phenomena the fluid encounters can cause instantaneous changes in the condition of the tank, resulting in occasional cracking or leaking. This research aims to determine how the design shape of a 5000-liter tank affects surface pressure. The method utilized is the finite element method based on computer-aided engineering (CAE) with the software Ansys Workbench Student Version. The results demonstrated that the maximal stress value and total deformation of the Model 2 tank were significantly different from those of the Model 1 and Model 3 tanks. The tank variation of the model is known to have the lowest stress value of 1.1309 MPa and the lowest deformation value of 0.0042421 mm. Therefore, the Model 2 tank variants are more recommended than the Models 1 and 3 for vehicles with a 5000-liter capacity.

Abstract

The company has a raw material warehouse to carry out its production process, but the warehouse needs to be optimized because employees experience limited access to raw materials and the current warehouse layout is still not optimal. This research was conducted to find out the proposed improvements to the raw material warehouse layout so that the company can optimize the function of the existing raw material warehouse within the company. The Shared Storage Method can be used in layout design by arranging storage areas according to the condition of the warehouse floor area. The shared storage method assists in optimizing product storage time so that you can find out when the product will enter and leave the warehouse storage area. The proposals obtained influenced increasing the previous warehouse capacity. There was an increase in capacity of 21.5%. The proposals obtained influenced increasing the previous warehouse capacity. The results of the research on the application of the design for the new layout, at one level, have a warehouse capacity of 33 pallets with ± 14 tons of product. However, by optimizing warehouse capacity by adding one level above it, the warehouse capacity can be doubled, namely 66 pallets with 28 tons of product with product placement between the first and second levels of the same level. The use of warehouse layouts is intended for new image layouts from this study.

Abstract

This study investigates the effect of variations in the micro geometry with various forms as passive flow control devices on the aerodynamic capability of the airfoil. Micro-cylinder, micro-slat, and micro-cube are installed close to the leading edge of the NACA 4415 airfoil as a micro geometric variation of passive flow control devices with a predetermined diameter of 3% c located at coordinates x= 0% c and y= 8 %c of the leading edge of the airfoil. The Reynolds number used in this study is Re = with AoA variations from 0°-30°. This study's results show a decrease in Cl of 12% with a micro-cylinder, 26% with a micro-slat, and 28% with a micro-cube. In addition, the Cd produced by using the variation of the device micro geometry has increased significantly. Thus, the final result is a lift-to-drag ratio of more petite than the without micro. In the streamlined contour shown when the airfoil is at a high angle of attack, the use of micro geometric variations of passive flow control devices can have an effect that causes reduced recirculation that occurs in the airfoil. However, the impact of these devices is not optimal, resulting in a reduction in the aerodynamic capability of the NACA 4415 airfoil.

Abstract

Several influencing factors, including temperature, air cleanliness, and humidity levels, are necessary to preserve the performance and durability of engine components against injury. Many mechanical and electrical components of the machine were damaged at Company X because the room's temperature, air quality, and humidity did not comply with the machine's standard operating conditions. If nothing is done to enhance the engine room's air conditioning, the engine will sustain greater damage. The purpose of this research is to design a cooling and air-conditioning system in the production machine space in PT. X to maintain the performance and durability of machine components. The engine compartment is 104 m2. The design of the refrigeration and air conditioning systems includes the calculation of the required capacity, analysis, and the creation of design drawings in the engine compartment. According to the calculation, the required engine room refrigeration capacity unit is 9.36 kW with 1640 l/s. This capacity incorporates the requirement for fresh air, which is 245 l/s. With this capacity, the engine's optimal temperature and oxygen quality can be attained.
