Abstract

Corrosion is the degradation of metal quality caused by a reaction between the environment and the material. Generally, corrosion problems are caused by water. However, there are several factors other than water that influence the corrosion rate, such as temperature. An increase in temperature in a corrosive system will increase the rate of corrosion. This is caused by an increase in the active energy of the particles involved in the corrosion reaction. The aim of this research was to determine the effect of temperature and firing time on the corrosion rate of ASTM A 572 steel material. The research method used was experimental, using ASTM A 572 steel plates measuring 5 cm wide and 7 cm long with a thickness of 5 mm with the heating process used being 3 hours, 5 hours and 7 hours at temperatures of 600oC, 650oC and 700oC. The results of the research on the effect of temperature and firing time on the corrosion rate of ASTM A 572 steel material showed that the lowest average corrosion value was 0,3947 mm/year with a testing time of 3 hours at a temperature of 600oC. Then the highest average corrosion value was obtained, namely 8,0937 mm/year with a testing time of 7 hours at a temperature of 700oC

Abstract

Elektroplating adalah proses pelapisan logam dengan logam lain di dalam suatu larutan elektrolit dengan pembiasan arus listrik. Pelapisan metode elektroplating dapat menghasilkan permukaan yang memiliki karakteristik sesuai dengan logam pelapis. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh waktu pelapisan terhadap hasil pantul cahaya dan ketebalan lapisan pada plat baja karbon rendah dengan panjang 70 mm, lebar 35 mm dan tebal 3 mm. Metode penelitian yang digunakan yaitu metode eksperimen dengan variasi waktu pencelupan 5 menit, 10 menit dan 15 menit. Kondisi pelapisan menggunakan tembaga sebagai logam pelapis (anoda) dengan dua buah anoda yang berada di sisi kanan dan sisi kiri katoda, pada jarak antara anoda-katoda  5 cm. Hasil yang diperoleh dari penelitian ini adalah dengan variasi waktu pencelupan elektroplating tembaga yang dilakukan, nilai pantulan cahaya dan ketebalan lapisannya meningkat, yaitu pada waktu pelapisan 5 menit mendapat ketebalan lapisan 0,27 mm dan nilai pantulan cahaya 14,2 lux. Pada waktu pelapisan 10 menit mendapat ketebalan lapisan 0,77 mm dan nilai pantulan cahaya 19,5 lux. Pada waktu pelapisan 15 menit mendapat ketebalan lapisan tertinggi 0,99 mm dan nilai pantulan cahaya tertinggi 25,1 lux

Abstract

An incinerator is a high-temperature waste-burning device with a closed, insulated combustion chamber, designed to minimize environmental impact [1]. Modern incinerators aim to reduce inorganic waste and smoke emissions, particularly in Metro City, Lampung Province [2]. A key component is the wheel, which reduces friction and enhances mobility [3]. This study focuses on designing the incinerator wheel, determining its geometry and material, and analyzing stress, strain, and deformation through simulation [4]. The design process used Autodesk Inventor Professional, while simulations were performed in SolidWorks [5]. Tests were conducted under three load conditions: no load, 250 kg, and 500 kg. The final wheel design measures 150 mm in diameter, 50 mm in width, and 10 mm in thickness, using cast iron. Simulation results show stress, strain, and deformation remain below material limits, even at 500 kg load, confirming the wheel’s safety and reliability for optimal incinerator performance.
