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

This study developed an environmentally friendly composite material for use in roller weights of Continuously Variable Transmission (CVT) systems in motorcycles. The composite, made from teak wood powder (Tectona grandis L.F.) and epoxy resin, was formulated as an alternative to conventional PTFE (Polytetrafluoroethylene), which is less environmentally sustainable. The composite was fabricated using the hot-press method, with variations in the teak-resin composition ratios (60:40, 70:30, and 80:20) and hot-press temperatures (160°C, 170°C, and 180°C). The results showed that the composite with a 60:40 composition at 180°C and 20 bar pressure achieved the highest tensile strength of 25 MPa, exceeding that of conventional roller weight material (23 MPa). Tensile testing was conducted in accordance with ASTM D3039 standards. In addition to its superior mechanical performance, the material also utilizes biomass waste and has the potential to reduce production costs. These findings demonstrate that teak wood powder composite is a viable candidate for strong, durable roller weight applications and supports the development of more sustainable automotive components.

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.

Abstract

Abstract--Flow Depth can be defined as channel height or open channel flow depth, is an important parameter in hydraulic calculations and analysis. The depth of flow in the U channel (U channel) of the Student Practice Room (RPS) for Automotive Light Vehicle Engineering (TKRO) at SMKN 1 Ciruas often causes delayed flow congestion and full channels. Sometimes it is dry if only a few students carry out practical use of room practice and use of water and other waste. The aim of this research is to find a solution to this problem, namely by knowing the depth of flow in the channel so that in the future when designing waste water drainage channels it can be designed appropriately and in accordance with the volume of waste released. The method is to calculate the flow depth in the U channel using NEWTON RAPHSON numerical analysis and the Matlab application to determine the flow depth. The calculation result is the depth of water flow in channel U, with water flow discharge Q = 0.016 m3/s, Manning coefficient for roughness of channel walls and base n = 0.025, slope of channel bottom I = 0.003, and width of channel U B = 0.22 m, at The 11th and 12th iterations flow depth = 0.194864 m. The results of manual exact calculations in the 11th and 12th iterations, the error percentage is 0%, meaning that the flow depth is uniform at a water level of 0.194864 m. Calculations using the Matlab application obtained graphs and the iteration steps were slightly different in the 12th and 13th iterations, the flow depth results were the same = 0.194864 m. The initial guess at flow depth(h)=1, the percentage error is 25%, the uniform flow depth of the RPS TKRO SMKN 1 Ciruas U channel is 0.194864 m.Keywords : Depth of flow, NEWTON RAPHSON, Open Channel, U Channel, MATLAB

Abstract

Composites are a combination of matrix or binder materials with reinforcement. The combination will produce a composite material that has different mechanical properties and characteristics from the constituent material, so that a desired composite material can be planned. The abundance of natural resources of palm fiber from palm trees but its utilization is still lacking, due to the mechanical properties of this fiber which is still in doubt about its reliability. For this reason, it is necessary to conduct research on epoxy resin composites with fibers as a filler so that the mechanical properties of each fiber and matrix composition can be known. The study used an experimental method that began with the manufacture of composite materials for the test specimens using an epoxy resin matrix reinforced with fibers with fiber volume fraction variations of 0%, 5%, 7% and 9%. Testing the mechanical properties of composite materials, which in this case is testing the torsional strength and impact strength of composite materials with variations in some fiber content, is then carried out simulations using the test data. The results of this study obtained an optimum average impact strength of 13.00 kJ/m on a composite material with a fiber content of 9% and obtained an optimum torsional strength with an average torque value of 271.14 N.m and an average stress value. shear of 2698.48 MPa on a composite material with a fiber content of 9%. The data obtained shows that the higher the percentage of fiber used, the greater the impact strength and torsional strength produced by the fiber-reinforced composite material.
