Abstract

Penelitian ini bertujuan untuk meneliti pengaruh perendaman media Asam klorida konsentrasi 3% terhadap kekerasan Alumunium dan Baja karbon. Bahan yang digunakan dalam penelitian ini adalah baja karbon rendah AISI 1018, aluminium 6061, asam klorida (HCl) 3 %, air. Uji kekerasan menggunakan Mesin Rockwell (HRC type C). Hasil uji kekerasan menunjukan baja karbon rendah lebih keras dibandingkan alumunium. Sebab kedua spesimen memiliki perbedaan struktur mikro dan kepadatannya. Dan juga hasil diatas menunjukan bahwa benda uji yang telah direndam dilarutan HCl tingkat kekerasannya berkurang sebab telah terjadi proses korosi dan pelunakan struktur mikronya.

Abstract

This study aims to analyze the differences in engineering aptitude-mechanical reasoning among engineering students. This study is a quantitative study with a cross-sectional study design. This study was conducted at the Faculty of Engineering, Ogan Komering Ilir Islamic University, Kayuagung (UNISKI). The subjects of this study were selected by simple random sampling so that the number of samples obtained was 26 students of the mechanical engineering study program and 36 students of the civil engineering study program. The instrument used in this study was the aptitude-mechanical reasoning test developed by Mackellar (2015). This instrument consists of several topics, namely 1) Levers, 2) Pulleys, 3) Gears, 4) Springs, 5) Simple electrical circuits, and 6) Tools. The research data were analyzed using the RASCH Model Analysis using the WINSTEP application. The results showed no significant difference between mechanical engineering and civil engineering study programs in pulleys, springs, and electrical circuits. In the element of levers, gears and tools, the t count value is greater than the t table, so there is a significant difference between mechanical engineering and civil engineering study programs.

Abstract

This study aims to determine the comparison of the effect of air flow velocity on the corrosion rate and hardness of aluminum and carbon steel materials. This study is an experimental study using specimens, namely Aluminum 6061 and low carbon steel AISI 1018. The results showed that 1) the immersion current velocity for 2 days obtained the following results, for the speed with a distance of 12 cm from the dynamo, a speed of 0.073 m / s was obtained for aluminum. Something that is not much different is also obtained for the speed of low carbon steel where with a distance of 12 cm from the dynamo, a speed of 0.075 m / s was obtained. 2) The difference in weight between before and after immersion in the specimen shows that in aluminum the weight difference is smaller than the weight difference in low carbon steel. 3) The corrosion rate of low carbon steel is higher than aluminum. This shows that aluminum is more resistant to corrosion
