Abstract

This study aims to determine the effect of alkali concentration on the thermal properties of HDPE composites with water hyacinth and carbon nanotubes (CNTs). The method used in this study is the experimental method. Composites made of natural fiber filler, the alkali treated water hyacinth. The water hyacinth was also filled was treated in alkali solution at various concentration (0%, 2%, 4%, 6%, and 8%). In addition to using water hyacinth fiber, the carbon nanotube (CNT) in a matrix of high-density polyethylene (HDPE). The composites were made using Rheomix OS machine. Furthermore, thermal testing of composite specimens using machine Thermogravimetric Analysis (TGA) were conducted. The results obtained from testing the thermal properties is the thermal resistance value. Thermal resistance of composites with alkali treatment of 0%, 2%, 4%, 6%, and 8% were 258,9 0C, 259,5 0C, 260,3 0C, 264,0 0C, and 265,9 0C, respectly. Based on these results it can be concluded that the concentration of NaOH improves the thermal resistance of the composite.

Abstract

Pengecatan adalah salah satu upaya untuk menjaga penampilan bodi kendaraan, dikarenakan pengecatan memiliki fungsi untuk melindungi material dari terjadinya karat. Oleh sebab itu, dilakukan penelitian terkait sintesis cat epoxy dengan variasi suhu pengeringan agar diperoleh komposisi yang tepat untuk mendapatkan karakteristik yang baik. Penelitian yang sudah banyak dilakukan hanya berfokus pada temperatur oven pengeringan saja, namun pada penelitian ini waktu pengeringan oven menjadi salah satu hal yang juga diperhatikan. Hasil penelitian yang didapatkan pada penelitian ini adalah semakin tinggi temperatur pengeringan dengan waktu pengeringan yang sama dapat menurunkan nilai penampilan dan kemampuan daya kilap serta ketebalan lapisan cat. Berlawanan dengan hal tersebut, ternyata tingginya suhu pengeringan tidak memiliki pengaruh terhadap kemampuan daya lekat cat apabila dilakukan waktu pemanggangan yang sama, yaitu 20 menit.

Abstract

The turning process is essential in the manufacturing industry to produce a product. The quality of a product is greatly influenced by the turning process, which produces varying roughness characteristics of the product's surface. The selection of suitable cutting parameters greatly influences the surface roughness of the product from the turning process. Therefore, a study was carried out on the cutting parameter's effect on the workpiece's surface roughness. In this research, the material used was ST 41 steel with a diameter of 25.4 mm. The turning process uses a conventional lathe. Variation in this study is the cutting speed and feeding depth. The results showed that the higher the cutting speed, the smaller the surface roughness value. On the contrary, the greater the feeding depth, the greater the surface roughness value.
