Kincir air dipasang sesuai dengan kebutuhan minimal pada bulan pertama pemeliharaan. Pada bulan kedua pemeliharaan, total kincir harus sudah terpasang sesuai dengan target produksi berdasarkan data SR terakhir. Sebuah tambak tidak memerlukan kincir hingga produksi biomassa udang mencapai 500 kg/Ha dengan pertumbuhan normal. Kincir dapat tidak dipasang pada biomassa 700 kg/ha dengan pertumbuhan lambat. Untuk pertumbuhan tetap normal, kincir dipasang ...

Effect of calcium carbonate (CaCO3) in water can also be expressed as the hardness of the ability of water to form foam when mixed with detergent (soap). On the water has a low hardness will easily form foam when mixed with soap. While on the water that has high hardness would not form foam. Hardness is very important for the ...
