Abstract

Piping installation is a medium for fluid transfer which has many design variations. The design used can affect the flow rate of the fluid. The effect comes from head losses which are divided into major losses and minor losses. Basically, major losses are losses caused by straight pipes while minor losses are losses due to pipe components. These components can be in the form of bends, connections, branching and changes in cross-sectional size. Losses that occur in pipe flow can be studied by direct simulation. To carry out a direct simulation, a test tool is needed that can help analyze losses that occur in fluid flow in pipe installations. The design that is carried out refers to the use of pipe installations that are often encountered including its components. The system design of the flow loss test equipment is selected using the VDI 2221 method. The selection of components is carried out by comparing the variations in the arrangement of system components. From the results of this comparison, the best variation was obtained with the results of the main PVC pipe, 108 bit Shimizu jet pump, ball valve type, pressure gauge capacity of 2.5 bar, flowmeter capacity of 1.5 m3/h, rotameter capacity of 2-20 GPM/10- 70 LPM. The tool has been completed built and tested so it is feasible to use.

Abstract

Steel has various physical and mechanical properties. The very high hardness of steel makes it difficult to form or process with a machine. Based on these problems, there needs to be a treatment (treatment) that can improve the mechanical properties of steel. The annealing process is the process of heat treatment of metals or alloys by heating the metal to austenite temperatures, holding it at that temperature for a while, and cooling the metal at a very slow cooling rate. The heat treatment process aims to improve the mechanical properties of the metal or alloy. In this study, SUH 35 steel was used as the test material. Eight test materials are prepared, namely four materials Unannealed and four materials treated with annealing. Annealing specimens are given heat treatment with a temperature of 750 ° C ± 10 ° C with a holding time of 60 minutes. This specimen is carried out by turning process with variable machining feeding that varies 0,25 mm/revolution, 0.50 mm/revolution, 0,75 mm/revolution, and 1 mm/revolution. The results of this study show that the annealed material has a lower roughness value of 311.49 VHN. In comparison, the Unannealed sample has a hardness value of 607.59 VHN, which shows better machinability in the annealed material. The results of the feeding variation show that the greater the feeding value, the more it will affect the increase in the roughness, resulting in the surface grinding process.

Abstract

Piping systems are a major component in oil and gas processing facilities in Indonesia. With piping usage increasing every year, safety is a critical priority to avoid fatalities and losses due to piping damage. In order to ensure safety and reliability, a thorough analysis of piping stress analysis is required at design and operation stages. Piping stress analysis aims to assess the risk of stresses arising from various factors, including changes in temperature, internal pressure, and external environmental conditions. This study conducted a literature review of 51 international journals published between 2014 and 2024, focusing on factors that affect piping stresses analysis such as force loads, pipe support, piping layout, vibration, earthquake, and cryogenic service conditions. Based on this study, it was found that force load pressure & temperature, determining pipeline layout, pipe support location and vibration have a impact on pipe stress distribution, which in turn affects piping reliability and service life. Analysis using software such as CAESAR II proved effective in identifying critical areas on the piping and ensuring that the system performs in accordance with established safety standards. The review shows that piping stress analysis not only maintains safe operational limits but also improves piping reliability. With proper application of stress analysis, the risk of failure can be minimized, and the service life and reliability of the pipeline system increased. This application is important to maintain production continuity and minimize potential losses due to damage to the piping infrastructure.

Abstract

This research aims to assess carbon fibre's physical and mechanical properties and potential use to improve vehicle efficiency. The main focus is to reduce vehicle weight, improve fuel efficiency, and lower carbon emissions. Carbon fibre has a tensile strength of more than 6 GPa, a modulus of elasticity of more than 600 GPa, and a density of 1.8-2.0 g/cm³. Its use in vehicles can reduce weight by 86%, improve fuel efficiency by 20%, and significantly reduce carbon emissions. The carbon fibre sandwich composite structure with an aluminium honeycomb core increases strength and reduces weight by 36%. Carbon fibre also improves the vehicle's rollover resistance by 64% and energy absorption by 60%. However, high manufacturing costs are a major challenge, with precursor materials such as polyacrylonitrile (PAN) accounting for about 50% of the cost. Biomass-based alternatives, such as lignin and agricultural waste, can reduce costs, although they require further development. Research shows that integrating recycled carbon fibre in metal-polymer hybrid structures can reduce vehicle weight by 48% and improve structural performance. This research emphasizes the importance of manufacturing innovation and the exploration of alternative materials to maximize the utilization of carbon fibre.

Abstract

Aluminum waste is a challenging material to manage due to its high production rate from households and industries. This study aims to repurpose aluminum waste into hydrogen gas, which can serve as an alternative fuel for gas stoves. Direct disposal of aluminum waste can lead to environmental damage; hence, this project focuses on developing a system that dissolves aluminum using sodium hydroxide (NaOH) to produce hydrogen gas in a tube reactor. This hydrogen is then used as stove fuel. The comparison between aluminum-fueled hydrogen and conventional fuels, such as Pertalite and LPG, suggests that aluminum waste has potential as a cost-effective fuel source. For instance, one liter of Pertalite at Rp. 10,000 powers a motorbike for approximately 30 km, translating to Rp. 1,428 for a similar distance with aluminum-derived fuel. A 3 kg LPG cylinder costs around Rp. 24,000 and provides 10 hours of fuel, whereas hydrogen produced from aluminum can be cheaper if sourced from waste. Additionally, this design incorporates a refillable reactor that sustains hydrogen supply during combustion, ensuring consistent stove operation. The system is portable, safe, and offers high mobility, making it practical for various applications. This approach not only reduces aluminum waste but also presents an affordable alternative fuel solution, enhancing environmental sustainability.

Abstract

Abstract - The rapid advancement of aviation technology necessitates rigorous structural evaluations to ensure safety and efficiency. This study focuses on analyzing water ingress in sandwich composite structures used in the cabin floor of the Airbus A330, employing Non-Destructive Testing (NDT) and simulation methods. Using thermography, areas with water ingress were identified, with darker regions indicating trapped moisture within the composite layers. Two cases were analyzed: one with areas requiring repair and another within acceptable damage limits as per the Structure Repair Manual (SRM). The study simulated the effects of pressure and temperature using ANSYS. Results revealed minimal pressure differences, with values ranging between 0 and 0.80 atm. Temperature simulations showed a range of 21°C to 24°C, suggesting potential condensation that could lead to water ingress. Structural simulations evaluated the composite's deformation, elastic strain, and stress distribution. The maximum deformation was 5.1138 mm, with elastic strain peaking at 0.0033772 mm/mm and stress von Mises reaching 591.74 MPa, well within the material's safety threshold. This research highlights the importance of periodic inspections and advanced simulation techniques in maintaining composite structures. Recommendations include utilizing additional NDT methods, such as ultrasonic testing, to enhance detection accuracy and investigating actual cabin conditions to refine future analyses.

Abstract

This research was motivated by the lack of utilization of wasted plant parts so that there were previous extractors that had been made but were still not optimal. This study itself aims to determine the effect of changes in the driving power of natural plant fiber extractors on the extracted fibers compared to previous extractors so that later the fiber produced can be used as the main material for making natural composites. In this study, the extractor is a tool used to extract plant fibers lining banana stems. The method used in this study is by developing the previous extractor, especially in the drive motor that used to use a DC motor and then replaced with a 5.5 HP gasoline motor, drum blade cap, tool transmission and water drain slide. After the development of the extractor was carried out, it continued with the initial data collection process with the loading method with an average banana stem layer length of 165.5 〖mm〗^2 and an average weight of 6.91 kg where the results can be used to determine the power of the drive motor used in this tool. The process of extracting plant fiber from banana stem layers to determine the influence of the quality and quantity of fiber produced after tool development. As a result, the time needed to extract plant fibers averaged 9.3 seconds compared to previous tools which averaged 37.6 seconds manually and 42.3 seconds with DC motors.
