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.

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.

Abstract

A composite is a material structure formed from a combination of two or more materials, processed on a macroscopic scale and physically fused. To improve the characteristics of natural fibers in composites, a NaOH alkalization process is carried out which influences the fiber composites. Real experimental strength of the composite. The results showed that Alkalization of NaOH in water hyacinth fiber with variations in resin and fiber fractions (40%, 50%, 60%) and concentration (5% and 10%) affected the impact value. Specimens with a 60% resin and fiber fraction that experienced 5% alkalization showed the lowest impact, while a 40% resin and fiber fraction that experienced 10% alkalization had the highest impact. These findings indicate that NaOH alkalization significantly affects water hyacinth fibers, potentially increasing strength due to the removal of lignin, hemicellulose, and pectin. Loss of these components can make the fiber more brittle and susceptible to damage. In testing the resin and fiber fractions (40%, 50%, 60%) with varying concentrations (5% and 10%) when mixing fiber with matrix, it was found that the 60% resin and fiber fraction with a concentration of 5% had the lowest impact strength of 61 J/mm2, while the resin and fiber fraction of 40% with a concentration of 10% has the highest strength of 82 J/mm2. The results of this research highlight the importance of optimizing the volume fraction of fiber and epoxy matrix to improve the impact characteristics of water hyacinth fiber composites.Keywords: composite, alkalization, volume fraction, fiber, water hyacinth

Abstract

The automotive industry is one of the industries that is currently developing in Indonesia. Research has been carried out on materials used in the automotive industry, one of which is improving the mechanical properties of low carbon steel which is widely used as sprocket material. Sprockets are parts of a motorbike that require surface hardness and ductility at the core. So carburizing treatment is the right treatment to increase the wear resistance of low carbon steel. The material used in this research is ST 37. This research aims to increase the surface hardness of ST 37 by varying the carburizing temperature, where the temperatures used are 850℃ and 900℃ with a holding time of 3 hours. Wear resistance testing uses the weight loss method by comparing the ST 37 sprocket with sprockets sold on the market. The highest wear resistance was obtained on sprockets with carburizing treatment at a temperature of 900℃ with test results of 1.65 x 10-2 mm3/hour.
