A car wash is a facility used to clean the outside and inside of a car, which can be done manually and automatically. The use of an automatic system allows car washing to be faster than a manual washing system that still relies on human labor. The car washing machine pre-design article provides an overview of automatic car washing pre-design. This planning uses the Autodesk inventor application with 6061 aluminum material with a design size of 80 mm × 80 mm × 5 mm. In this plan, the planned water requirement is 300L/car, where the nozzle radius r₁ = 25 mm, r₂ = 10 mm, and nozzle pressure of 24,410 Pa with 24 nozzles. Electric power is used at 1310 watts where the pump pressure is 34,872 Pa. All frame loads and other supporting components were analyzed using Autodesk Inventor^TM software. The maximum stress and strain, deflection and safety factor of the frame were also analyzed. This article presents the design of the controller system using Arduino. The general design of the water circulation system is also shown in the design proposal of this machine.

Noise is the occurrence of unwanted sounds including irregular sounds and sounds emitted by transportation and industry, so that in the long term it can disturb and endanger work concentration. The purpose of making this silencer test equipment is to determine the level of sound that can be heard properly. .Methodology used: In an impedance tube, two microphones are placed at one end of the impedance tube and a sound source is placed on the other side. Two microphones were placed between them which were used to measure differences in the acoustic impedance of the sound field produced. The results of the research carried out were the creation of a sound dampening device. This research was carried out in three stages, namely the stage of making sound dampening equipment. In this study, two types of specimens were used, namely from wood powder waste and cigarette butt waste with a thickness of 1 cm with a frequency used of 500 Hz, (wood dust = 0.0164. Cigarette butts = 0.0164) 1000 Hz (wood dust = 0 .0097, cigarette butts = 0.0114) and 1500 Hz.(wood dust = 0.0107, cigarette butts = 0.0139

Currently, the gantry crane still uses steel material. The steel is protected using a coating paint to minimize the impact of corrosion. However, this method is inefficient given the high rate of corrosion due to its coastal location. This also causes maintenance issues because repainting must be done regularly and periodically. Additionally, not all equipment has annual maintenance funding. The aim of this study is to design and analyze the stress of a 9-ton capacity gantry crane using Aluminium 6061 material. Finite element analysis was conducted using Autodesk Inventor Professional 2024 software. The results of this study indicate that the gantry crane frame is safe to use because the von Mises stress analysis result of 2,778 MPa is still below the yield strength of Aluminium 6061 material, which is 275 MPa. A safety factor of 2.07 shows that the gantry crane design is very safe to withstand loads up to 9 tons.

Frames are often used as essential elements in the construction of machines and various other engineering products. The strength of the frame is significant in ensuring that the structure can withstand operational loads when used. Frame failure can cause severe damage, accidents, and substantial financial losses, so evaluating the strength of the frame before production is a critical step in the design process. This study aims to analyze the mechanical behavior of the components or frames of the patchouli chopping machine based on the maximum stress, displacement, and safety factor of the designed frame. The research method using finite element simulation technology is an efficient approach to analyzing the performance of frame structures. By utilizing simulations, a comprehensive evaluation of various parameters such as stress, displacement, and frame safety can be carried out. This process helps predict the structure's response to multiple loads received by the system. The simulation results using the finite element method show that the L-profile frame 40x40x3 mm with a cross-sectional area of 307.863 mm² can withstand a maximum load of 1000 N with a maximum deformation of 0.2479 mm, which occurs at the load center. The von Mises stress distribution shows that the stress that occurs in the L-profile steel is 28.8 MPa. This value is far below the material yield strength threshold of 207 MPa. The maximum Safety Factor value that occurs in the frame is 15 ul, and there is no safety factor value below 1. The simulation results show that the analyzed frame is safe and meets the specified design requirements

Cow dung is one of the abundant energy resources, especially in rural areas, which has the potential to become an option in reducing people's dependence on fuel oil. This study aims to analyse the characteristics of biogas from cow dung as an alternative energy. The effect of paddy straw on the biogas production rate and flame characteristics was also analysed. The parameters studied were temperature, pressure, and detected gas on biogas production and flame characteristics. The results showed that biogas from cow dung produced a light blue biogas flame, with a pungent odour at a retention time period of 14 days. Flame characteristics with blue colour were observed on the 21st day of retention time, and the pungent odour (considered as a sulphur, and a carbon monoxide) was relatively reduced. Combustible gases were identified by the gas detector as EX; 100%. Other elements such as sulphur and carbon monoxide were indicated as H₂S and CO by the gas detector. The intensity of these two elements decreased as the retention time increased up to 28 days. The addition of the straw of 10% of the cow dung increased the pressure rate and mass of biogas produced on day 7. The biogas combustion test on day 14 showed that the addition of straw reduced the intensity of methane gas, which was characterized by a pale blue flame due to the dominance of carbon monoxide. The effect of straw addition on biogas intensity was observed on day 21, in which the visual intensity of the flame was greater than the feedstock without the straw. In the retention time above 21 days, the straw biomass has been completely degraded, thus increasing the intensity of the burning gas flame. This study recommends carefully handling of straw biomass for additional feedstock and catalyst in the biogas production of cow solid manure such as shredding, ideal composition, and pre-treatment of non-degradable substances.

Advances in technology made the use of fossil fuels a major issue, while the sources of fossil fuels continue to decrease due to their perishable nature. Biomass, including waste such as sawdust and oil palm empty fruit bunches, has potential as an alternative energy source that can be converted into briquettes. This study aims to determine the characteristics of biomass sawdust and oil palm empty fruit bunches as briquette materials as an alternative to fossil fuels. This research was conducted experimentally to determine the optimal formulation of a mixture of Wood Powder (SK) and Empty Palm Bunches (TKKS) in making briquettes. Composition variations tested include 100% SK, 100% TKKS, 50% SK: 50% TKKS, 70% SK: 30% TKKS, 30% SK: 70% TKKS. The results showed that the ultimate and proximate characteristics of 100%SK and 100%TKKS have good fixed carbon content. Based on the heating efficiency test, the best value is with the composition of 100% SK with 10% starch adhesive getting a combustion efficiency value of 7.65%. The best porosity index was obtained in the formulation of 70% SK: 30%TKKS with a value of 1.52%, while the best durability index is in briquettes with a composition of 100%TKKS with 10% starch adhesive getting a value of 0.12%. The briquette properties of sawdust and empty palm kernel can be the initial data in the development and use of biomass briquettes or co-firing fuel for industrial furnace because it has good mechanical and physical properties. Thermal efficiency test in the field should use biomass stoves to obtain accurate biomass performance data.
