Tujuan dari penelitian ini adalah untuk meneliti pengaruh 0,25 % Molibdenum (Mo) yang dikandung dalam besi tuang nodular terhadap sifat mekanis Austempered Ductile Iron (ADI). Variasi temperatur dan waktu tahan digunakan dalam proses perlakuan panas. Dengan 0,25 % Mo dalam besi tuang, ADI yang dibuat, menghasilkan suatu nilai tegangan tarik yang besar dan menurunkan elongasi bila kita bandingkan dengan as-cast (paduan dan non paduan besi tuang tanpa perlakuan panas). Nilai energi impak terbesar didapat pada ...

a complex system with multiple variables, feedback loops, and is influenced by
social, economic and environmental factors. The proposed model consists of two
submodels: Vehicle Fleet and Emission Calculation. The model runs in
Powersim Studio software using data from the Indonesia Japan Economic

forced vehicle manufacturers to invent suitable engines that would accept
biodiesel. The use of biodiesel in such a large proportion is highly risky,
particularly due to the formation of deposits in the combustion chamber
engines. The previous method of fuel droplets are placed on a hot plate
approach produces deposits are slightly different from those ...
