Abstract

Car wheels have an important role in supporting the load of the vehicle, so the wheels are required to have the strength and design that can withstand the weight of the vehicle. Good wheels must be able to withstand the weight of the vehicle as well as the collisions that occur during the use period. The collision that occurs will cause stress on the wheel material. The magnitude of the stress can be simulated using computer-aided engineering (CAE)-based software. This study simulated collisions in the case of an impact test with the SAE 175 standard, with an impact of 3200 Newton, and the wheel material used was ASTM A299, which has an elastic modulus of 200 GPa and a yield strength of 275 MPa. The wheel design has a design difference that lies in the V-shaped spokes, with the V angle for the model 1 wheel being 22°, the model 2 wheel being 50°, and the model 3 wheel being 90°. The simulation results on the values of stress and strain show that the greater the value of the V angle of the wheel, the smaller the value of the stress and strain produced due to the collisions imposed on the wheel. This is due to the better ability of the wheel design with a larger wheel V angle value to spread the stress and not accumulate at a critical point

Abstract

This study aims to carry out pneumatic trainer motion simulations using Festo Fluidsim 3.6 software programming simulation. The trainer design has three main parts, namely a frame made of iron, a programmable automatic control device in the form of a PLC, and the third is a mechanical movement device in the form of a pneumatic circuit. This tool will be integrated into a circuit system, which is then tested with three experiments based on circuit simulations made in the Festo Fluidsim 3.6 software. The test results from 3 simulation experiments show that the PLC control system can send signals to the mechanical motion of a single-acting cylinder. The PLC control system can also send signals to the mechanical motion of a double-acting cylinder with non-simultaneous motion. Other than that, the PLC control system can send signals on the mechanical motion of a double-acting cylinder with simultaneous motion. The three experimental tests found that the number of strokes for a single-acting cylinder was more than that for a double-acting cylinder. The three tests showed that they could move the cylinder well with variations in flow control, namely the flow control openings of 25, 50, 75 and 100%.

Abstract

Plastic injection (injection molding) is a method of forming products from plastic pellets into various daily necessities products. In terms of supporting daily needs, plastic injection molded products must meet criteria, such as strength, ductility, flexibility, hardness, etc. One of the easiest ways is to do a tensile test. In this research, mold with the shape of tensile test specimen products was carried out through several process stages, namely design and simulation, fabrication, and product testing. Autodesk Fusion 360 software is used in the design process to simulate and predict material flow during the injection process into the mold with several parameter variations in the form of time, material temperature and mold temperature. The results obtained were by using polypropylene (PP) plastic material, the maximum injection conditions were by suing a melting temperature of 230°C and a mold temperature of 50°C with an injection time of 14.5 seconds, where it was predicted that the product would be easy to fill and the resulting quality would reach 100% good. This research has succeeded in designing and predicting a plastic injection process that can be utilized in the plastic molding process through the actual injection process in industries that use polypropylene material.

Abstract

Gas Metal Arch Welding (GMAW) adalah suatu metode pengelasan yang saat ini sudah banyak digunakan di industri manufaktur. Hal ini dikarenakan GMAW memiliki beberapa keunggulan seperti pengelasan yang cepat dan dapat digunakan dalam berbagai posisi dan material. Namun demikian, cacat pada las berupa porositas masih sering terjadi, sehingga untuk mendapatkan hasil yang maksimal melalui teknik pengelasan GMAW masih diperlukan penelitian lebih lanjut secara ekstensif. Penelitian ini bertujuan untuk mempelajari mengenai pengaruh pengaturan voltase terhadap kekuatan tarik hasil las GMAW, yang mana sangat dipengaruhi oleh porositas hasil lasnya. Dalam hal ini, material yang digunakan yaitu berupa pipa STKM 13B dan pelat SPH 440. Pengelasan antara pipa dan pelat secara saling tegak lurus memiliki kemungkinan yang besar untuk terjadinya porositas pada hasil las, sehingga sangat menarik dan penting untuk diteliti. Arus yang digunakan pada penelitian ini yaitu 110 Ampere dengan variasi voltase 18, 20, dan 22 Volt. Hasil pengelasan menunjukkan bahwa pengelasan dengan voltase yang meningkat menunjukkan peningkatan kekuatan tarik dari material yang sudah dilas. Namun demikian, pada sampel dengan voltase 20 V menunjukkan hasil terbaik yang terjadi dikarenakan pada hasil foto mikro terlihat bahwa pada sampel tersebut tidak terdapat porositas atau paling tidak minim porositas. Lebih lanjut lagi, nilai standar untuk area las menunjukkan bahwa pengelasan dengan voltase yang tinggi mendukung tercapainya standar ketebalan, kedalaman, dan panjang las yang disarankan. Penelitian ini berhasil memberikan gambaran hasil kekuatan tarik dari las GMAW pada material pipa dan pelat dengan perbedaan nilai tegangan

Abstract

Engineering and innovation in the manufacturing process will continue to be carried out. This aims to ensure that there are always improvements in every product made, both in terms of design, materials used, and how the production process is carried out. Product design innovation is often also aimed at efficiency and reducing product production costs. Innovation in a product must be to improve, not reduce the value and usefulness of the product being made. The aim of this research is to determine the distribution of stress and strain as well as the safety factor of carabiners as hanging accessories using polypropylene polymer material. The research uses experimental methods, namely observing the simulation results that occur in the form of stress, strain and safety factors, as well as knowing the cause and effect phenomena that occur in the design of a carabiner for an accessory. By changing the shape of each design to the upper end of the frame in the direction of the carabiner gate, R15, R30 and R45. As well as varying the load given by 10 N to 100 N, with an increase in force of 10 N in each simulation carried out, with axial and vertical loading directions. By ignoring the type of gate and the shape of the connection on the carabiner gate. The different shapes in each carabiner design cause differences in the tension distribution that occurs. The R15 design has a maximum stress value at a load of 100 N, namely 25.03 MPa, the R30 design is 33.78 MPa, and the R45 design is 63.61 MPa. The vertical loading direction achieves a good safety level of 4.0 at a load of 20 N in the R15 and R30 designs. Meanwhile, axial loading does not achieve product safety targets. The difference in calculating the factor of safety is 4.0 between the results of computer computing and the results of analytical calculations using a formula, namely 1% of the maximum limit of 5%.

Abstract

This research explores the mechanical properties of composites made from Polylactic Acid (PLA), chitosan, and calcium phosphate, which have potential applications in bone tissue engineering due to their biocompatibility and biodegradability. This research aims to optimize the strength and durability of composites for biomedical use, with a focus on tensile strength, elongation and surface hardness. This research found that the addition of calcium phosphate increased the tensile strength and hardness of the PLA matrix to optimal concentrations, the highest tensile strength value of 80 MPa while chitosan increased elasticity and ductility. The hardness test results show an average value of 309 HV/100. The combination of these materials produces a balanced composite with better mechanical properties, making it suitable for bone implant applications.

Abstract

The accumulation of waste in the environment has become a critical issue, necessitating effective solutions, one of which is pyrolysis technology for treating waste such as tires and cables. Pyrolysis is a thermal degradation process that occurs under limited oxygen conditions, producing gas, tar, and char as byproducts. This study aims to evaluate the effect of varying zeolite catalyst ratios on the amount of oil produced and the production rate in the pyrolysis process of cable waste, tire waste, and their mixture. The catalyst ratios used in this study were 100, 200, and 300 grams, along with a control condition without a catalyst. The results indicated that the use of 300 grams of zeolite catalyst produced the highest oil yield, with 141 ml from cable waste, 233 ml from tire waste, and 238 ml from the mixed waste. In contrast, the absence of a catalyst yielded the lowest oil production, with 64 ml from cable waste, 85 ml from tire waste, and 137 ml from the mixed waste. These findings suggest that the use of zeolite catalyst significantly enhances both the production rate and quantity of oil compared to the condition without catalyst.

Abstract

Pada industri pengolahan makanan, efisiensi dan kualitas mesin pemotong kentang menjadi faktor krusial dalam produktivitas. Penelitian ini bertujuan untuk menganalisis pengaruh variasi jumlah lubang pada pisau pemotong kentang terhadap kapasitas efektif pemotongan, efisiensi pemotongan, dan keseragaman hasil potongan. Eksperimen dilakukan menggunakan mesin pengupas dan pemotong kentang sederhana dengan tiga variasi pisau pemotong (36, 64, dan 144 lubang) dan tiga variasi tekanan pneumatik (6, 7, dan 8 bar). Hasil penelitian menunjukkan bahwa pisau dengan 144 lubang pada tekanan 8 bar menghasilkan kapasitas efektif pemotongan tertinggi (123,51 kg/jam) dan efisiensi pemotongan tertinggi (97,71%). Namun, peningkatan jumlah lubang juga menyebabkan sedikit penurunan dalam keseragaman hasil potongan, dengan nilai error tertinggi 0,5048% pada pisau 144 lubang dan terendah 0,5019% pada pisau 36 lubang. Penelitian ini menyimpulkan bahwa peningkatan jumlah lubang pada pisau pemotong kentang dapat meningkatkan kapasitas dan efisiensi pemotongan secara signifikan, meskipun dengan sedikit dampak pada keseragaman hasil potongan.
