Abstract

This study aims to understand the temperature distribution in the natural circulation system in the Intermediate Tank FASSIP-07 using the Computational Fluid Dynamics (CFD) method. Simulations were performed using Ansys Workbench R1 2024 software, with inlet temperature variations of 70°C, 80°C, and 90°C. The results showed that the highest temperature distribution was found at the inlet with a temperature of 90°C, while the outlet reached the lowest temperature at 70°C. This conclusion was obtained from the analysis of fluid flow driven by the buoyancy phenomenon due to differences in density. This study shows the potential for using a passive cooling system for nuclear reactors to improve safety in emergency conditions.

Abstract

Prosthetic hands are designed to help people with disabilities work. This research aims to make a prosthetic hand using a 3D printing machine with a focus on using Solidworks software for model design, Ultimaker Cura software for slicing printing in the form of G-Code, and filler material in the form of PLA filament. The main components used involve a servo motor (MG996), Arduino Uno, and breadboard. This research focuses on making designs using solidworks, using servo motors (MG996), and using PLA filament material. The data collection process is divided into three stages: design creation, G-code creation, and printing, as well as the data collection process which involves trial and error on the prosthetic hand. The results of this research show that although in general all the fingers of the prosthetic hand can move, there are some fingers that experience problems following program commands. Factors such as design, manufacturing defects, hinges, and connecting straps between the servo motor and the finger affect the movement of the prosthetic hand's fingers. Although some fingers can move well, there are also those who experience difficulty in movement.

Abstract

Linflow water meter is a smart technology-based water consumption meter designed to improve accuracy and efficiency in water resource management, both in the household, commercial, and industrial sectors. To protect the sensitive components inside and ensure the durability of the tool in a wide range of environmental conditions, a reliable case design is required. This study aims to design and analyze the linflow water meter casing by considering the aspects of pressure resistance, protection against moisture and temperature, as well as conducting static and thermal analysis to evaluate the structural integrity and performance of the water meter, ensuring that it meets industry standards for efficiency and durability. The methodology used includes the selection of materials that are resistant to stress and corrosion, the design of ergonomic casing structures, and durability simulations using the finite element analysis (FEA) method. The results of the analysis show that the high-quality polymer material with the addition of an anti-corrosion coating provides optimal protection for the operational environment. In addition, the modular design of the case makes it easy to install and maintain without affecting the integrity of the device. These findings are expected to improve the design process and operational reliability of water meters, thereby supporting effective drainage management and infrastructure protection.

Abstract

Coal mill (pulverizer) is used to grind coal into micro-sized particles suitable for combustion. This study aims to analyze the preventive maintenance applied to the coal pulverizer to prevent damage and improve operational efficiency. Preventive maintenance procedures include routine tasks such as visual inspection, lubrication, cleaning, and component tightening. During the process, problems such as hydraulic pipe leakage and other component malfunctions are identified and immediately addressed to prevent further impacts. Preventive maintenance has proven effective in minimizing the risk of unplanned downtime, supporting sustainable production, and improving the efficiency of the coal pulverizer. The operational principle of the pulverizer involves grinding coal between the grinding roller and the grinding table, assisted by airflow from the primary air fan to produce coal powder with a size of 200 mesh, ready for combustion in the burner. In conclusion, preventive maintenance is very important to maintain equipment performance, reduce potential damage, and ensure smooth production processes.

Abstract

The installation of photoelectric sensors as a supporting element for the development of a pneumatic transfer system based on Programmable Logic Controller (PLC) in the Kartini Reactor aims to enhance efficiency and accuracy in operational processes. This study integrates photoelectric sensors to detect capsules in the pneumatic transfer system, which previously required manual intervention. The sensors send signals to the PLC, which controls actuators automatically. The system was optimized through installation, calibration, and testing, involving the measurement of capsule speeds for both empty capsules and those containing 3-gram samples. Results indicate significant operational efficiency improvements, with average transfer speeds of 12.41 m/s for empty capsules and 11.76 m/s for filled ones. This integration significantly contributes to advancing reactor automation systems based on PLC technology.

Abstract

Oil palm is a plant that produces palm oil which is widely known as Crude Palm Oil (CPO). Palm oil is refined into crude palm oil (CPO) and palm kernel. Kernel quality parameters include dirt content, water content and percentage of broken kernels. The kernel breaking process uses a Ripple mill machine. The Ripple mill machine is a part that determines the quality of the kernel in production at the kernel station and causes problems when the machine does not work effectively. Common problems faced by companies are frequent sudden machine breakdowns and production results do not meet the specified production criteria. In analyzing machine performance, both production and machine efficiency, the method is carried out by taking samples at the chute sampling point every 2 hours while the machine is operating with different sample weights. The sample is stirred until homogeneous so that whole nuts, broken nuts and broken kernels do not pile up. Then the sample is divided into four or quarts, take two opposite parts and put them in a container. The sample is weighed with a sample weight of 1 kg, pour the sample for analysis by separating whole nuts, broken nuts, and broken kernels. Then weigh the whole nuts and broken nuts, record the weighing results, from the weighing results do calculations using the formula to determine the efficiency of the Ripple mill.

Abstract

Bearing is one of the main components in the gear reducer pumping unit that plays an important role in supporting the performance of the output shaft. In working conditions, this component receives high loads that can affect deformation, stress, and bearing life. This study was conducted at PT Bukaka Teknik Utama with the aim of analyzing the total deformation, Von Mises stress, safety factor, and bearing life using Ansys Workbench R1 2024 Student software simulation. The analysis was carried out by creating a bearing geometry design using SolidWorks 2024, determining AISI 52100 material, meshing, giving radial and axial loading, and static analysis simulation. Specific data, such as 32230 SKF bearing specifications and load values, were used to ensure the accuracy of the results. The results of the analysis showed a maximum deformation value of 0.17348 mm, a maximum Von Mises stress of 76.579 MPa, a minimum safety factor of 5.876, and an average bearing life of 1.057 x 1012 hours. From the analysis that has been done, the results obtained are that the bearing life is too large due to the limited mesh size and the small loading given so that the results obtained are inaccurate. The results of the analysis indicate that the bearing is in a safe condition to support the given load. This study recommends improving the quality of meshing in the simulation to obtain more accurate results.
