Abstract


PT. APIE Indo Karunia produces is a casting company that produces steel and iron
part such as gear. The casting processes include material melting, mold making process using
silica sand, moldcoating process, and pouring the melted metal into the mold. These processes
use a huge amount of energy that affect to environment. Thus, the calculation of eco-efficiency
ratio for PT. APIE Indo Karunia is needed.
The eco-efficiency ratio in months February, March and April are 1,06, 1,15 and 1,09
respectively. While, the eco-efficiency of the total production on energy consumption are 1,22, 1,2
and 1,226. These values are higher than the Indonesian energy eco-efficiency which valued 0,46.
It means that the production process of PT. APIE Indo Karunia is still inefficient in terms of
energy consumption .
