Abstract

Aircraft are highly complex transportation modes, assembled from various components to ensure optimal safety and reliability. One of the small yet essential components frequently used in aircraft is the nut, which generally exhibits corrosion resistance due to its stainless steel 304 material. However, corrosion can still occur, particularly in areas such as the galley, landing gear, lavatory, and engine construction. This study aims to develop a specialized tool to facilitate aircraft maintenance by effectively removing corroded nuts. The tool was designed using CAD SolidWorks and manufactured through turning, grinding, milling, and welding processes. It operates by clamping the nut and applying impact force until the nut breaks, utilizing a sharp blade to destroy the nut without damaging surrounding aircraft components. Torque testing was conducted to measure the rotational force capacity for various nut sizes. The test results demonstrate that the developed tool can efficiently, safely, and effectively remove corroded nuts, thereby simplifying aircraft maintenance and reducing the risk of damage to other components.

Abstract

Drying machines have a vital role in food products drying for packaging to avoid bacteria contamination and ensure its durability. A properly designed dryer is utterly fundamental to maintaining adequate drying capacity, especially to overcome the ever-changing weather. In aiming for the pre-described drying rate, numbers of parameters need to be considered, such as the drying temperature, airflow speed, temperature distribution, and humidity. Henceforth, a comprehensive study considering all these parameters is necessary during the dryer machine design process. Employing numerical simulation is a solution to reduce the required cost and time from the experimental approach. This study proposed a set of vermicelli dryer designs with various inlet and outlet damper openings of 30%, 45%, and 60%. The study shows that the openings affect the temperature gradient and drying rate. The most optimum design is obtained at the damper opening of 30%, whereby the drying time, temperature gradient, and vermicelli temperature of 23,99 minutes, 2,98 oC and 57,9 oC respectively.

This study aimed to design and develop a pneumatic-based eco-paving block printing machine that uses plastic waste as its primary raw material. The research methodology encompassed the design and simulation of pneumatic circuits, structural analysis involving stress distribution, displacement, and factor of safety (FOS), and strength testing of the fabricated eco-paving blocks. The machine was equipped with a pneumatic cylinder measuring 80 × 75 mm, operating at a pressure of 6 bar and generating a maximum pressing force of 300 kg. The simulation results confirmed that the maximum stress and displacement remained within safe limits, with a minimum FOS of 8.4, thereby ensuring a stable and reliable design. Testing of the eco-paving blocks revealed compressive strengths ranging from 38 to 54 MPa, surpassing the requirements of the SNI 03-0691-1996 standard. This study demonstrates that a pneumatic-based eco-paving block printing machine effectively transforms plastic waste into high-quality construction materials compliant with national standards, offering a practical solution to the plastic waste crisis while promoting sustainability in the construction industry.

Abstract

The wood pellet machine is one of the Special Purpose Machines (SPM) that has an important element as a driver. One of the damaged machine elements is the broken roll shaft due to long-term use. The roll shaft functions to hold the roll so that it does not rotate during the wood pelletizing process. Failure analysis was carried out on the roll shaft, starting with a redesign using the IMRC method. The stages of this method are incremental, elemental, and radical stages. The redesign strategy chosen was an incremental redesign. This redesign changes the core component but does not change the mechanism or function. The results obtained after the redesign, obtained changes in the dimensions of the roll shaft so that it does not break with a value above the permitted control value. The largest shaft diameter becomes 70 mm, the diameter at the critical part becomes 60 mm and the length of the spline construction becomes 50 mm. With this change in diameter, a safety factor for the shaft was obtained after the redesign with a value of 6.83 and is categorized as safe.
