Abstract
Penelitian ini bertujuan untuk : (1) Menguji pengaruh variasi temperatur awal cetakan Centrifugal Casting terhadap nilai kekerasan, (2) Menguji pengaruh variasi temperatur awal cetakan Centrifugal Casting terhadap struktur mikro benda hasil pengecoran. Metode penelitian yang digunakan adalah metode eksperimental, data hasil penelitian diambil dengan cara mengamati secara langsung hasil eksperimen kemudian menentukan dan menyimpulkan hasil penelitian dengan cara ditampilkan dalam bentuk tabel dan grafik. Analisis hasil data penelitian didahului dengan uji normalitas untuk mengetahui apakah data hasil penelitian berdistribusi normal atau tidak. Selain itu juga dilakukan uji homogenitas yang bertujuan untuk mengetahui data hasil penelitian merupakan data yang homogen atau tidak, dan yang terakhir dilakukan uji Anova One-Waydan Post Hoc Test guna mengetahui apakah terdapat pengaruh yang signifikan antara variasi temperatur awal cetakan Centrifugal Casting terhadap nilai kekerasan dan struktur mikro benda hasil pengecoran. Analisis data dilakukan dengan program SPSS 16. Dari hasil penelitian dapat disimpulkan bahwa: (1) Terdapat pengaruh antara temperatur awal cetakan Centrifugal Castingterhadap nilai kekerasan benda hasil pengecoran, karena hasil uji analisis data yaitu 0.00 < 0.05 .Terdapat pengaruh antara temperatur awal cetakan Centrifugal Castingterhadap struktur mikro benda hasil pengecoran This study aims to: (1) Test the influence of early temperature variation of centrifugal casting mold to hardness value (2) Test the influence of early temperature variation of centrifugal casting mold to micro structure of thing the result casting. The result method used experimental method, data the result of research was taken by observing directly the experimental result the determine and summarize the results of research by displayed in the fom of tables and graphs. Analysis of the dataresults of research data is preceded by the normality test to determine whether the data research of results are homogeneus data or not, and the last, conducted test Anova One-Way and Post Hoc Test to determine thether there is significant influence between early temperature variation centrifugal casting mold to value pf hardness and foundry micro structure. Data analysis wasperformed with SPSS 16 program. The results of study can be concluded that; (1) There is an influence between early temperature variation of centrifugal casting mold to the hardness value thing the result of casting, because the result of the test data analysis is 0.00<0.05. There is an influence between early temperature variation of centrifugal casting mold on the micro structure of thing the result casting. Early termperatur variation which has the greatest influence is on the variation of mold temperature 150°Cto 350°C raw temperature with significant value 0.000 and mean difference equal to .28883.
