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.

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

The lack of technology is one of the barriers for someone to be more developed than before. Science and technology today are the backbones of economic development. This is what happened in the family planning village (KB) in Tulungrejo Village, Ngantang District, Malang Regency. The low level of technology is one of the obstacles to maintaining product quality and the health of the majority of Tulungrejo villagers. The abundance of raw materials obtained directly from the mountain is not matched by this increasingly sophisticated technology, causing the production process to be underdeveloped. On the other hand, the residents of Tulungrejo Village seem to have forgotten the importance of using personal protective equipment. The production process still uses traditional equipment so that the manufacturing and marketing processes are hampered. The manufacture of cobek lathes is expected to improve quality, speed, and reduce risks to health. Because the equipment used by the majority of the KB village community in Tulungrejo village uses personal protective equipment that is not following what it should be. One of them is not wearing a mask according to national standards, so it has the potential for health because the dust generated from the mortar manufacturing process can interfere with breathing. The result is that the use of a lathe can cut production time faster than the use of a grinder that is usually used by residents to produce the mortar, the work is neater and even, the production time is faster than the use of a grinder, and in terms of K3 the use of a lathe is safer because the mortar is direct. clamped on the lathe so that it is stronger and the resulting dust can be minimized with water cooling media.

Abstract

Graphene Oxide is a material that has a thickness of one atom composed of carbon atoms to form a hexagonal lattice and a material that has unique properties, namely mechanical, optical, thermal, and electrical properties. Fe2O3 is a material that has magnetic properties and can be used for various applications such as enzyme separation, drug transport, microwave absorption, photocatalysts, biological applications, biomedicine, metal separation, and magnetic resonance imaging (MRI). In this study, the addition of graphene oxide was carried out using the coprecipitation method on Fe2O3 nanomaterials that had been treated with sintering and non-sintering. The coprecipitation method is the synthesis of inorganic compounds which is based on the deposition of more than one substance together when it passes the saturation point. The purpose of this study was to determine whether the addition of graphene oxide to the Fe2O3 material can increase the magnetic properties of the Fe2O3 material or vice versa. The result was that the sintering treatment on Fe2O3 GO did not have a transforming effect on its magnetic properties, but instead had a changing effect on its magnetic value. However, the magnetic coercivity value of Fe2O3 + GO 700 ºC increased to 0.038 Tesla. Thus, it can be concluded that at a temperature of 700 °C graphene oxide acts as a barrier from external magnetic fields in the opposite direction.

Abstract

Salah satu nilai lebih dari kendaraan bermotor adalah  bentuknya yang menarik atau mengikuti trend mode, untuk mencapai bentuk yang menarik tersebut harus dirancang pula konstruksi dari komponen mesin tersebut agar sesuai dengan bentuk rancangan. Tujuan dari penelitian ini adalah mengetahui pengaruh variasi sudut pelat pemanas dengan laju aliran udara terhadap besarnya koefisien perpindahan kalor konveksi. Metode penelitian yang digunakan adalah eksperimental yang digunakan untuk menguji pengaruh dari suatu perlakuan atau desain baru terhadap suatu proses. Hasilnya semakin besar sudut yang terbentuk antara pelat pemanas dengan arah aliran maka perpindahan panas yang terjadi dari pelat menuju udara semakin kecil hal ini ditandai dengan menurunya koefisien perpindahan panas konveksi, penurunan ini disebabkan semakin besar sudut yang terbentuk antara pemanas dengan arah aliran maka luasan pemanas yang mengalami perpindahan panas secara konveksi akan semakin kecil.
