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

Frame mengunakan material ASTM A36 H beam. Penelitian ini merupakan penelitian kekuatan struktur rancang bangun frame mesin uji diesel jetman tipe R175A mengunakan sofware ansys workbench R2 2020 versi academic sebelum pembuatan frame, dan juga Analisa getaran frame mengunakan piezoelektrik sembagai alat sensor pengambilan data getarannya. Bahwa hasil perhitungan 60 kg equivalent stress dengan simulasi ansys menunjukan nilai equivalent stress maksimum yang terjadi pada kondisi terbeban adalah 0,0026529 MPa. Nilai tersebut hanya terjadi di beberapa titik dan tidak melampaui nilai tegangan luluh ASTM A36. Berdasarkan hasil simulasi static struktual dengan pembebanan sebesar 60 kg di ketahui nilai maksimal total deformation sebesar 0,00047065 mm. Dari hasi simulasi dapat diketahui bahwa bagian frame jika warnanya mendekati warna merah artinya bagian frame tersebut semakin mendekati nilai maksimal total deformation. Hasil gelombang sinusoidal pengambilan data dengan 1000 rpm dan 2000 rpm menggunakan piezo A1 dan piezo A2 peletakan di tengah frame menghasilakan gelombang amplitudo, di mana piezo A2 lebih besar getarannya dari pada piezo A1 karena letak piezo A2 berdekatan dengan roda gila yang mengakibatkan gelombang lebih tinggi. Hasil gelombang sinusoidal pengambilan data dengan 1000 rpm dan 2000 rpm menggunakan piezo B1 dan piezo B2 peletakan samping frame menghasilakan gelombang amplitudo, di mana piezo B1 lebih besar getarannya dari pada piezo B2 karena letak piezo B1 lebih dekat dengan mesin yang mengakibatkan gelombang lebih tinggi, peletakan mesin diesel tidak senter dengan frame.
