“…Supaya materialnya berkualitas, dapat ditambahkan campuran material seperti chrome, silikon, titanium, aluminium, dan lain-lain. [6]. Proses pengecoran merupakan salah satu cara pembuatan produk, yang melibatkan peleburan logam dalam tungku peleburan kemudian dituangkan ke dalam rongga cetakan yang menyerupai bentuk asli produk tuang yang akan dibuat.…”

Aluminum is a non-ferrous metal that is widely used in everyday life, both on a large and small industrial scale as well as a household scale. In this research, used diesel motor piston material for casting screw. The addition of 0.1%, 0.3% Titanium Boron (Ti-B) and 0.1%, 0.3% Magnesium (Mg) for screw making by casting is expected to improve the physical and mechanical properties of the material. Tests carried out in this research are to wear testing and microstructure. The analysis of the results of this wear test shows that the aluminum alloy for making screws with the addition of 0.1% Titanium-Boron (TiB) and 0.1% Magnesium (Mg) has a better wear resistance, which is 1.154 mm² / kg compared to the addition of the element 0.3% Titanium-Boron (TiB) and 0.3% Magnesium (Mg) and without the addition of any elements which have wear resistance values of 1.252 mm² / kg and 1.596 mm² / kg, respectively. Microstructure testing shows the grain structure in aluminum alloy from casting results with the addition of Ti-B and Mg elements getting smaller and denser. This proves that the more elements of Ti-B and Mg added to the casting of aluminum alloys, the smaller the structure of the grain will be and will affect the mechanical properties of the screw.

“…Hal tersebut memiliki arti bahwa porositas akan memiliki nilai kecil seiring dengan meningkatnya temperatur cetakan. Kemudian penelitian yang dilakukan oleh (Wisnujati & Sepriansyah, 2018) melakukan pengecoran paduan aluminium dengan variabel temperatur molding dan perlakuan panas terhadap cetakan logam (dies) yaitu 450°C dan 500°C. Tegangan tarik maksimun rata-rata sebesar 774,74 N/mm2 dihasilkan pada pemanasan suhu cetakan 450°C.…”

This study describes the microstructure phase and the hardness value produced in metal casting with variations in metal mold temperature with the addition of Ti-B elements. gravity casting, a technique that relies solely on gravity, is used for casting metals. This objective of this study to determine the mechanical properties characterization of specimens using die casting molds by varying the mold temperature between 250°C, 350°C, 450°C and the addition of 0.05% Ti-B alloying elements. In addition, this research can determine the right temperature for metal casting by gravity casting method. The material used in this research is recycle piston Al-Si (series 4xxx). The results of hardness testing at a temperature of 250°C have produced 123.9 HVN. The microstructure of the Al-Si-TiB alloy material has dense grain boundaries. This is because the casting with the addition of the TiB element functions as a grain refiner and reduces porosity in the microstructure. So, the smaller the porosity, the stronger the hardness of the specimen or material. This is because at low mold temperatures, the metal casting process will freeze faster, resulting in higher hardness. In addition, the increasing temperature of the die casting mold has a tendency to change the eutectic structure of silicon to primary silicon.

“…Berbagai macam metode pengecoran telah ditemukan dan disempurnakan, diantaranya centrifugal casting, investment casting, dan sand casting serta masih banyak lagi metode-metode lainnya. Pada penelitian ini paduan Aluminium akan dicor pada 3 jenis variasi suhu cetakan sehingga dengan perlakuan panas terhadap cetakan logam (dies) yaitu 450 o C dan 500 o C diharapkan mampu memperbaiki sifat getas yang ada pada Aluminium [9].…”

The car door is one of the important components in a car, as a means of getting in and out of passengers and goods. This study aims to compare the factors of safety, strength, shear stress, and dimensional changes due to the received load, between car doors made of bamboo composite material and car doors made of aluminum. The research method is carried out in the form of simulating the load on the car door using Fusion Autodesk 360 software. The data used in this study is secondary data obtained from data analysis from journal articles related to bamboo and aluminum fiber composite materials. Strength simulation using loads of 100 N, 150 N, and 200 N refers to the strength simulation reference. Based on the simulation results, it can be concluded that the car door made of bamboo composite has good yield strength, safety factor, and shear strength and has the potential to be an alternative material to replace aluminum car doors, especially at low loads. The results of modeling using software with the above load, the safety factor values are in the range (10-15) and the displacement is in the range (3-4) mm. The results of this simulation become one of the references in further research and development.
