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

ABSTRACTGMAW (Gas Metal Arc Welding) is a fast, versatile welding technique that can be used in various positions, but it often results porosity in welded joints.This research aims to analysis of the welded joints of STKM13B pipe and SPD 440 plate using tensile and micro testing, using welding a current of 18 and varying voltages of 110, 130, and 150. The results is the shape of the welded joint of the plate and pipe is perfectly connected, the tensile test results showed that the ultimate strength values for specimen 1, 2, 3 (A110/V18, A130/V18, A150/V18) were (18,959, 27,886, 40,005 N) respectively. The highest ultimate strength values were obtained from the specimens (A150/V18) while the lowest ultimate strength value was obtained from specimen (A110/V18). The use of welding current strongly correlates with ultimate strength value and photomacro results, with higher currents resulting in higher density levels, minimizing porosity, and increasing ultimate strength. Keywords: GMAW Welding, Tensile Test, Macro Optical Test.

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

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

The starter system is a component that serves to start or run an engine. Usually, the starter system on the single-cylinder engine is a conventional starter, which is still done manually by an operator. Modification activities in the form of adding an electric starter system have been carried out in this study. The focus of the study was carried out on the design of the brackets of the electric starter system. Bracket is a support plate component used as a stand for the starter motor system. In this design, 3 types of bracket models (Model 1, 2, 3) starter motors are designed with simulation testing and vibration tests on each bracket model. Simulation testing with the finite element method to determine the deflection value (deformation) and fatigue (equivalent stress) in the material used. Vibational testing is carried out to obtain design results that are able to withstand vibrations that occur in single-cylinder engines. Based on the simulation results, the bracket model ( Model 1) with a maximum value of total deformation of 0.00012047 mm with a load of 6.055 kg, while the result of equivalent stress the maximum value reached 0.26726 MPa. The model 1 also shows the ability to withstand the least vibration compared to the other two models.

Abstract

The increasing volume of waste in Indonesia, particularly plastic waste, has led to significant environmental challenges due to its continuous accumulation. Pyrolysis offers a sustainable alternative to conventional disposal methods, such as landfilling and incineration, which are known to contribute to pollution. Pyrolysis is a thermochemical decomposition process carried out in an oxygen-deficient environment, converting plastic waste into valuable products, including gas, oil, and char. These products have various applications: the gas can be used as a fuel, the oil as a liquid fuel, and the char as a solid fuel. This study investigates the pyrolysis of three types of plastic feedstocks: high-density polyethylene (HDPE), polypropylene (PP), and a 50:50 mixture of HDPE and PP. The catalysts employed were ZSM-5 zeolite, dolomite, and a mixed catalyst comprising ZSM-5 zeolite and dolomite, with a catalyst-to-feedstock ratio of 0.2:1. The results revealed that the highest oil yields were achieved using the ZSM-5 zeolite catalyst, producing 243 ml from HDPE, 370 ml from PP, and 380 ml from the HDPE-PP mixture. Conversely, the dolomite catalyst yielded the lowest oil production, with 82 ml from HDPE, 20 ml from PP, and 282 ml from the HDPE-PP mixture. Additionally, the ZSM-5 zeolite catalyst demonstrated a consistent increase in the oil production rate every 10 minutes across all feedstocks. These findings highlight the effectiveness of ZSM-5 zeolite in enhancing oil yield during pyrolysis, offering a viable pathway for converting plastic waste into valuable energy resources.

Abstract

Salah satu alat pemanen energi alternatif adalah generator Winbelt. Winbelt adalah alat konversi energi yang mengubah gerakan angin menjadi energi listrik. Dalam generator Winbelt terdapat suatu alat induksi eletromagnetik yang terdiri dari magnet dan kumparan. Karena gerakan angin yang mengenai belt, sehingga menggerakan magnet secara bolak balik terhadap kumparan, maka terjadilah induksi elektromangnetis yang dapat  menghasilkan listrik. Penelitian ini membahas pengaruh lebar Pita Winbelt terhadap energi listrik yang dihasilkan dengan variasi kecepatan angin yang diberikan. Metodologi penelitian melibatkan pembuatan beberapa prototipe Windbelt dengan panjang pita yang sama namun berbeda dalam hal tingkat kelebaran. Selanjutnya, prototipe tersebut ditempatkan dalam lingkungan yang dapat mensimulasikan angin atau aliran udara yang cukup untuk menghasilkan getaran pada pita. Tegangan listrik yang dihasilkan oleh setiap prototipe diamati dan diukur menggunakan perangkat pengukur yang sesuai. Setelah dilakukan pengukuran, didapatkan  nilai tengangan listrik tertinggi dihasilkan pada variasi lebar Pita 18 mm dan dengan kecepatan angin 3.0 m/s  sebesar 2,62 volt.

Abstract

The PLC System in Vertical Plastic Injection Molding Machine is an automated electrical system designed with sensor inputs controlled by a PLC Mitsubishi FX0s-20MR. It is supplemented with additional devices such as Proximity switches and Thermocouple PID-CX100. The research aims to analyze the heater temperature to control the movement of the injection piston for controlled movement, enhancing the efficiency of the molding injection process, and preventing operational errors that could affect the machine's condition, performance, and the molding results. From the experiments conducted, it was found that the settings producing specimens with near-perfect or perfect results were in experiments number 5 and 6. The injection time in these experiments was successfully adjusted using a timer setting in the PLC program, with an automatic injection time of 15 seconds. Based on these results, it can be concluded that the optimal settings for the molding process using PP material in this equipment are a temperature of 200-210°C, pressure of 4-5 bars, and injection time of 15 seconds.
