“The Cost of Quality and Accounting for Production Losses (Process Costing)“


“The Cost of Quality and Accounting for Production Losses (Process Costing)“

Internal Failure
·         Biaya produk yang rusak menjadi beban perusahaan (debet ke Factory Overhead Control).
·         Jika produk yang rusak bisa dijual, maka Hasil penjualannya di debet ke Spoiled Goods Inventory.  (FOH Control = Total cost produk rusak – Spoiled Goods Inventory)).

Ilustrasi:
Deco Pottery Company membuat gelas keramik dalam departemen yaitu departemen Molding dan Glazing.  Di departemen Molding ada proses pemanasan sehingga ada gelas yang pecah (M 100%, CC 80%).  Gelas yang pecah di departemen Molding tidak ada harga jualnya.  Gelas yang rusak pada departemen Glazing diketahui setelah proses selesai (M 100%, CC 100%).  Gelas yang sempurna dijual $2,5 per unit, yang rusak dijual $0,5 per unit.
