Abstract

Semua kegiatan Industri 4.0 pada manufaktur ini menimbulkan tantangan sekaligus peluang besar bagi teknologi pengelasan (welding) dan khususnya bagi pengembang peralatan pengelasan. Masalah kritis lainnya, yang sedikit diabaikan oleh banyak pendukung dan promotor Industri 4.0 adalah kenyataan bahwa jaringan sistem selalu membawa risiko keamanan. Oleh karena itu, konsep keamanan data dan komunikasi modern harus digunakan dalam memberikan perlindungan bagi jaringan fasilitas produksi. data-data tentang beberapa metode dan jenis pengelasan menjadi sangat penting dan kebutuhan utama untuk produksi di era industri 4.0. Data tidak harus spesifik, namun lebih bersifat eksploratif yang kemudian diolah menggunakan beberapa algoritma hingga mendapat hasil optimasi yang ideal dan terus berkembang. Karena bersifat eksploratif sehingga sejumlah data yang besar diperlukan. Jika dihubungkan dengan era Industri 4.0 saat ini, maka peran peneliti di dunia adalah menyediakan data hingga mengolah data menjadi solusi atau sistem yang baru pada proses manufaktur. Metode penelitian ini menggukanan eksperimental nyata dengan mengidentifikasi pengaruh kuat arus pengelasan SMAW menggunakan media pendingin oli terhadap uji tarik dan uji kerasnya. Jenis sambungan yang digunakan adalah Single V-Groove. Pengujian tarik penelitian ini menggunakan standar JIS Z 2201 1981. Pengujian kekerasan pada penelitian ini menggunakan metode Rockwell dengan bola baja (HRB). Hasil pengujian tarik menunjukkan, tegangan tertinggi secara keseluruhan terjadi pada sampel 140A. Tegangan maksimum tertinggi sebesar 74.92 kgf/mm2. Tegangan patahan tertinggi 60.60 kgf/mm2. Kemudian tegangan yielding tertinggi sebesar 56.93 kgf/mm2. Nilai keras tertinggi pada area las adalah 85 HRB terjadi pada sampel dengan arus 120A. Nilai keras tertinggi pada area HAZ terjadi pada sampel 100A dengan 62.67 HRB.

Abstract

The most widely used aluminum alloy in industry is Al2024 alloy. Aluminum alloys used for automotive components are required to have good strength. The purpose of this study was to analyze the distribution of precipitates, morphology and hardness of Al2024 alloy due to artificial aging in stages I, II, and III. The test results showed that the highest distribution of precipitates (CuAl2) was in Al2024 with the third-stage artificial aging variation, and the least distribution was in the I-stage artificial aging variation. The results of morphological observations on Al2024 due to multilevel artificial aging treatment using SEM, the microstructure of Al2024 was relatively the same. (homogeneous) at each level variation. The stratified artificial aging treatment on Al2024 causes the particle size at each level variation to be smaller with closer distances. Meanwhile, the hardness value of Al2024 increased. The highest hardness of Al2024 is in the specimen with the third stage of artificial aging treatment, which is 79.66 HRE, the lowest hardness is the first stage of artificial aging, which is 74.33 HRE.

Abstract

Aluminum-silicon alloys are widely used in the industrial world, one of which is because they have high wear resistance. The aim of this research is to determine the physical and mechanical properties of the Al-Si alloy after strengthening by mixing reinforcing materials. The research method uses Taguchi optimization and analysis of the physical properties of the Al-Si alloy test results. The results showed that the highest hardness value was obtained in the 7th experiment, namely with a rotation variation of 2000 rpm, temperature of 6000C, and holding time of 60 seconds. This result is in line with the results of the tensile strength test, where the highest tensile strength was also obtained in the 7th experiment. This result is supported by the results of other researchers, which show that the higher the rotation in the casting results in higher hardness. The results of the microphotographs show that all alloy materials have an even distribution of grains, the grain size appears small, and the dendrites in the raw Al-Si alloy appear small compared to other materials. The macro photo results show that all alloy materials have fractures that appear brittle, as evidenced by the fact that these fractures provide light reflection.

Abstract

Technological developments in the modern era have experienced quite a significant increase, one of which is the combustion motorbike. Several things that are of concern to continue to be developed in combustion engines are the fuel system, ignition system and valve mechanism. The aim of this research is to analyze the effect of variations in throttle and valve load on petrol and diesel engines to determine the performance of these engines. The method used in this research is an experimental method by providing throttle variations and valve load variations on petrol and diesel motorbikes. The results of this research are that on petrol motorbikes the throttle changes with a fixed load at Pi, Pm, Ni, Ne, Nm, Qe, ηe, and ηi. There is a correlation between rotation and throttle, where the higher the rotation and the larger the throttle, the higher the value of the throttle. Pi, Pm, Ni, Ne, Nm, Qe, ηe, and ηi. In diesel motors Pi, Pm, Ni, Ne, Nm, Gs, Gg, Qb, Qeg, Qe, Qpp, ηe, and ηi There is a correlation between rotation and throttle, where the higher the rotation and the larger the throttle, the higher the value of Pi. , Pm, Ni, Ne, Nm, Gs, Gg, Qb, Qeg, Qe, Qpp, ηe, and ηi.
