Abstract

Plastic objects are widely used and found in all places, from food packaging, household appliances, and electronic devices to vehicles. Generally, plastic is used as a substitute for glass, wood, and metal. Over time, the use of plastic has become an environmental issue. To address the problem of plastic waste, the government has introduced the 3R (Reduce, Reuse, and Recycle) initiative. One of the easily used tools in the recycling process is the injection molding machine. This process often results in product defects such as Short Shot, Flow Mark, and Sink Mark. The temperature in the injection process affects the melting point of the plastic and can influence various aspects of the manufacturing process and the final quality of plastic products. The heating duration affects the viscosity of the plastic material to be injected. The research conducted is experimental, and several tests were performed to determine the effect of temperature variation and preheat duration of the injection molding machine on product quality. Simulation results show that the higher the temperature used, the greater the resulting sink marks. The test results indicate that improper temperature and preheat duration usage will affect the occurrence of product defects. A temperature that is too low can result in high pressure during the injection process, preventing the material from filling the cavity maximally. Preheat duration and temperature are critical factors in the plastic manufacturing process, affecting melting points, flow quality, dimensional stability, and the mechanical properties of the final product. Proper control of heating duration, temperature, and other process conditions is essential to produce high-quality, defect-free plastic products. Keywords: Injection Molding, Preheat, Temperature

Abstract

The structural strength of locomotive bogies is crucial for bearing operational loads and absorbing engine vibrations to efficiently transmit torque to the train wheels. The traction rod, a critical component in this system, plays a key role in transferring power from the main engine to the locomotive wheels. With the CC300 locomotive engine producing 2.200 hp, the traction rod experiences significant loads, necessitating regular maintenance. Given that this component is currently imported, the company is striving to redesign the traction rod to ensure strong structural integrity for local production, reducing dependency on imports and optimizing maintenance costs. The redesign involves adding structures to the existing design to even out stress distribution and enhance safety factors. Finite Element Analysis (FEA) is utilized to compare the structural strength between the original and redesigned designs, resulting in significant improvements in load-bearing capacity and deformation reduction. Simulation results show variations in stress, deformation, and safety factors among the original design, the redesign by the company, and the redesign by the researchers. The original design exhibits a stress of 194,64 MPa, deformation of 4,2817 mm, and a safety factor of 1,2844. The company's redesign achieves a stress of 438,37 MPa, deformation of 3.4356 mm, with a safety factor of 0,5703. Meanwhile, the researchers' redesign shows a stress of 154,05 MPa, deformation of 4,4812 mm, and a safety factor of 1,6288.

Abstract

The train is one of the main modes of transportation used in various countries in the world, including Indonesia. The existence of an efficient railway network can support the mobility of people and goods. The safety and comfort of train travel is highly dependent on the condition of the railway facilities and infrastructure. The condition of facilities and infrastructure that meet standards will make the journey smoother and reduce the risk of accidents. With human mobility, the development of public transportation using trains in Indonesia also continues to increase. Damage to train tracks can cause disruption to comfort and endanger safety caused by excessive vibration during train travel, so regular maintenance and repair of the rails is required using a system called the Intelligent Railway Vibration Monitoring System (IRV-MS). The IRV-MS system still needs to be tested because the resulting vibration readings still require validation. The design of this shaking rig simulator is expected to be a solution in terms of vibration testing. This shaking rig can move in a vertical or horizontal linear direction with a linear motor as a driver and produce oscillatory movements. The design of this shaking rig simulator tool uses Solidworks software with 500 mm x 423 mm x 380 mm of dimension and later vibration animation will be simulated in the motion study feature in the software with input parameters of 3-10 Hz with a maximum stroke of 20 mm.

Abstract

Heavy equipment, such as excavators, plays a crucial role in infrastructure and mining projects. The demanding worksite conditions and production targets require excavators to maintain high productivity, which can lead to material failures. A critical failure observed in the CAT 320GC excavator was the fracture of the coil spring in the undercarriage system. Several factors can contribute to coil spring failure, including worksite conditions, material defects, inadequate maintenance, and operational errors. This study aims to identify the root causes of coil spring fracture by analyzing its mechanical properties. The research methodology includes chemical composition analysis, visual and microstructural examination, hardness testing, and impact testing. The findings indicate that material failure was primarily caused by corrosion on the surface, which accelerated the fracture process. Additionally, repeated excessive loads from track shoe movements contributed to fatigue failure. The coil spring material was identified as high-carbon steel, closely resembling the 51xx (Chromium Steels) type. The fracture exhibited brittle characteristics with a granular or crystalline pattern, and the average impact energy was measured at 0.1541 J/mm². The coil spring material demonstrated an average hardness of 522.83 VHN, confirming its high hardness but brittle nature. The microstructural analysis revealed a predominance of fine lamellar pearlite in the dark regions of the fractured area.

Abstract

Waste is a byproduct of production activities, both in the industrial and household sectors. Solid waste, commonly known as garbage, can be divided into organic and inorganic waste. Organic waste from households, such as food scraps and plant materials like wood, twigs, or leaves, can be converted into compost or organic fertilizer that has economic value. The process of organic waste treatment requires a mixer machine to blend the chopped waste with other additional materials. In this study, the design and construction of an organic waste mixer machine were carried out. The mixing mechanism uses two ribbon-shaped twisted (helical) blades that rotate in opposite directions. As they spin, they produce a rotating movement while shifting to the left and right, creating a more even mixing effect. The shaft and mixing blades are rotated by the main drive, a 1 hp single-phase electric motor with a speed of 1420 rpm. From the electric motor, the speed is reduced using a speed reducer gearbox with a 40:1 ratio, bringing the shaft and blade rotation speed to 35,5 rpm. The mixing force generated on the mixer blade is 752,6 N.

Abstract

The utilization of bamboo in architecture and construction as an eco-friendly alternative to wood is steadily increasing. While ovens are crucial tools in the production of laminated bamboo, particularly for heating during the bonding process, research on ovens specifically designed for bamboo lamination remains scarce. This study aims to optimize the design of laminated bamboo ovens using Computational Fluid Dynamics (CFD) simulations to achieve uniform heat distribution and maximize thermal efficiency. Three design iterations were tested: Iteration 1 with an air velocity of 4 m/s, Iteration 2 with 1.5 m/s, and Iteration 3 with 3 m/s. The results revealed that Iteration 1 exhibited uneven heat distribution, with initial temperatures reaching 1175 K before dropping sharply to 800 K. Iteration 2 showed slower initial heating, achieving a final temperature of 360 K, but heat distribution remained suboptimal. Iteration 3 delivered the best performance, achieving uniform and stable heat distribution near the target temperature of 473 K (200 °C). Overall, Iteration 3 demonstrated the most efficient thermal performance, not only meeting the target temperature with consistent heat distribution but also enhancing the overall heating efficiency of the oven.

Abstract

The underwing tank enclosure is a component of fixed-wing aircraft that was originally manufactured by a Spanish aerospace company, so all the tools and references were not available to the Indonesian aerospace company, one of which is the inspection process tool. This study aims to design a checking fixture to meet requirements and support the production process of the underwing tank enclosure component, ensuring efficient and compliant inspection processes for the Indonesian aerospace company. The research utilized CAD software to design the checking fixture and CAE software to analyze the structural strength of the main fixture frame using the Finite Element Method (FEM). The results include a checking fixture design employing checking pins to validate the dimensional contours of the underwing tank enclosure against specified geometric specifications. Structural strength analysis revealed a maximum Von Mises stress of 1,1119 MPa, a maximum deformation of 0,0074696 mm, and a minimum safety factor of 211,34, while the checking plate deformation analysis shows that the longitudinal checking plate component only experiences a maximum deformation of 0,0010525 mm, confirming that the main structural frame of the checking fixture and checking plate components are safe for use. Keywords: Design, Checking fixture, Inspection, FEM.
