Abstract

One of the critical components of an excavator's undercarriage is the coil spring, which frequently breaks due to extreme working conditions, lack of routine maintenance, and material defects. This coil spring failure often occurs in the PC 78 excavator unit. The resolution of this issue requires an undetermined period of time. This problem can lead to decreased and suboptimal excavator productivity. The objective of this study is to identify the causes of coil spring fractures, evaluate its mechanical strength, and determine the type of material used. The methods applied include chemical composition analysis, microstructure examination, hardness testing, and impact testing. Visual observations indicate that the coil spring failure is caused by material fatigue, crack initiation, propagation, and final fracture characterized by beach marks and striations. Chemical composition analysis reveals the dominance of iron (Fe), carbon (C), chromium (Cr), and manganese (Mn), classifying the material as AISI 51xx steel. Microstructural examination shows a dominance of bainite, which contributes to the material's hardness. Vickers hardness testing indicates high hardness values consistent with the observed microstructure. Impact testing results suggest that the fractured specimen exhibits ductile behavior.

Abstract

The function of the frame on the electric motorcycle is to support the rider's load and where several motor components are combined, and also acts as the basic form of the motorcycle itself. The design of the electric motorcycle frame design also needs a finite element analysis. The analysis computes and produces formulas to estimate the actions that can be performed on the object, where this method involves dividing the structure into smaller elements connected by nodes or in other words, the discretization of elements. The objective of this research is to analyze the yield strength level of the electric motorcycle frame design under static loading conditions in accordance with the load safety standards of two-wheeled vehicles in Indonesia. The subject of this research is an electric motorcycle frame design with a naked bike frame type. The material used in the frame is aluminum alloy 6061 T6. The total loading during simulation is 265 kg. The quality of element discretization obtained in the electric motorcycle frame design is 0,278 with the size of each element of 5,5 mm. The maximum von Misses stress obtained is 125,3 MPa with a maximum deformation of 0,08618 mm and the safety factor is 2,154. The results of this study provide a statement that the electric motor frame design is able to withstand the load during simulation.

Abstract

Leg prosthetics as a device to increase the mobility of people with disabilities need to be supported in their development, especially in terms of comfort. Modifications to make prosthetics more comfortable to use are by utilizing the elastic properties of springs and base plate materials and dampers. This study analyzes the strength of steel and aluminium prosthetic base components in bearing the dynamic load of user's body. The analysis uses computational techniques with the finite element method. Computational results show that the most critical part of prosthetic, i.e. the base, is safe with maximum working stresses of 31,56 MPa for steel and 44,03 MPa for aluminium. Both materials are able to withstand the working stress.

Abstract

Waste refers to residual materials resulting from various human daily activities or natural processes that exist in solid form. In general, the term waste denotes unwanted materials or substances considered to have lost their usefulness after a certain activity or domestic process has been completed. To date, waste management efforts in many regions have not yet achieved optimal results. The level of public awareness and concern regarding environmental issues related to waste also varies significantly, making this issue an urgent environmental challenge that requires immediate attention and solutions. This study focuses on testing the effectiveness of waste treatment methods through the combustion process. The main objective is to determine the concentration levels of carbon monoxide (CO) and other hazardous gases generated during combustion, as well as to evaluate the performance of a waste incineration machine designed to produce low-smoke emissions. Gas concentration measurements were conducted using gas detection sensors integrated with an Arduino-based microcontroller system. The research approach combines both qualitative and quantitative methods. The qualitative aspect involves reviewing and comparing previous research findings, while the quantitative approach is carried out through direct measurements using a self-designed measuring instrument. This study is part of an ongoing research program aimed at developing a Low-Smoke Waste Incinerator Machine. Preliminary results indicate that the effectiveness level of the waste incinerator remains relatively low. This condition is attributed to the high concentrations of harmful exhaust gases such as carbon monoxide (CO), nitrogen oxides (NOx), and sulfur dioxide (SO₂) produced during the combustion process. In addition, the design of the incinerator has not yet reached optimal efficiency, as reflected by the persistently high NOx and SO₂ emissions. Therefore, more precise calibration of the gas sensors is required to ensure that the measurement data obtained accurately represent the actual concentrations of combustion gases.

Abstract

Leg prosthetics support the mobility of people with disabilities. Designing economical leg prosthetics is a major challenge for increasing accessibility for disabled people because the majority of them are from low income economy. Technically, the challenge is to make a cheap buat light weight prosthetics. Low cost metal raw material of prosthetics are often inversely proportional to the weight of components. One of the cheap materials, i.e. steel has a specific gravity 2.9 times higher than aluminum, which is lightweight but twice as expensive. This study examines the structural integrity of ankle prosthetic base components made of steel and aluminum when subjected to dynamic loads of the human body in a single step, using finite element method numerical computations. The goal is to determine whether the type of cheap material will be reliable in bearing the load. The computational results show that inexpensive materials such as mild steel and aluminum 6061 are able to support the mechanical structure of ankle prosthetic model to remain rigid while handling dynamic loads. The working stresses of both materials are still within safe limits, able to bear the load, even when multiplied by safety factor, the stresses are still below the yield stress value of each material. Aluminum 6061 is recommended for the production of lightweight versions of prosthetic models due to its maximum deflection that is really small as low as 4.41 x 10-3 mm, while mild steel is for the low-cost versions. Validation of the computational results was carried out using comparative literature data. Contact pressure value of 3 MPa from this research is in accordance with literature.

Abstract

Suboptimal household waste management remains a problem in various regions. Waste is generally disposed of in landfills (TPA) or burned openly, both of which have negative impacts on the environment. Open burning of waste produces air pollution in the form of carbon monoxide, dioxins, and fine particles that are harmful to health. Therefore, this study aims to design and manufacture a portable, smoke-free waste incinerator as an alternative solution for independent waste management. The research methods used include literature review, design using CAD software, component fabrication, tool assembly, and functional testing. This tool is designed with a combustion system in a furnace with controlled air flow to optimize the combustion process and reduce smoke emissions. The result of this study is a prototype of a portable waste incinerator that is easy to move. Based on the results of functional tests and visual observations, this waste incinerator can burn dry leaves, with the condition that there is still quite a lot of smoke at the beginning of the combustion and the smoke puffs are significantly reduced as the flame grows.
