Abstract

Dalam perhitungan biaya yang digunakan disalah satu Perusahaan Produksi dan Perawatan Kapalyang diteliti peneliti masih terdapat kelemahan yaitu perusahaan masih menggunakan perhitunganharga pokok produksi dengan metode tradisional dan perkiraan. Permasalahan yang ada di dalamperusahaan yaitu perusahaan belum melakukan perhitungan penyusutan peralatan dan mesin,kurang spesifik dalam menggolongkan biaya sesuai dengan jenis-jenis biaya, perusahaan hanyamencatat jumlah uang yang diterima dan dikeluarkan tersebut masih belum baku serta variabel danpenyusunannya masih belum detail terperinci tidak begitu akurat. Pencatatan yang manual dinilaikurang efektif dalam memenuhi kebutuhan informasi perusahaan. Perusahaan Produksi danPerawatan Kapal yang diteliti peneliti memulai kegiatan produksi Kapal berdasarkan pesanan yangditerima maka jenis metode perusahaan yang tepat digunakan adalah Job Order (pesanan).Perhitungan harga pokok di perusahaan berdasarkan pesanan maka dapat di tetapkan dengan JobOrder Costing dengan pendekatan secara full costing. Komponen biaya meliputi dua jenis biayayaitu biaya langsung dan tidak langsung.Perhitungan harga pokok produksi Kapal 30 GT pole andline menggunakan metode Job Order Costing sebesar Rp. 1.207.706.757,39. Perhitunganmenggunakan metode perusahaan sebesar Rp. 1.194.636.300,00 terdapat selisih sebesar Rp.13.070.457,99 lebih besar perhitungan Job Order Costing . Selisih ini disebabkan beberapakomponen biaya produksi pada perhitungan perusahaan tidak dihitung dan dikalkulasi.

Abstract

The manufacturing company located in Gresik is one of the companies that produce roll mill. Roll mill is a sugar plant equipment used for squeezing cane. In the calculation of cost of goods manufactured, the company does not include fixed overhead costs into the calculation of the cost of production. The calculation will be more accurate and detailed if the company uses job order costing method of full costing approach. The full costing approach calculates direct raw materials, direct labor, factory overhead costs, both variable and fixed. One example is PG.Pagotan orders where the results using JOC with full costing approach is Rp466.687.630,- for cost of goods manufactured, Rp93.337526,- for profit and Rp616.027.672,- for sale price. While the result set by the company is Rp438.625.790,- for the cost of goods manufactured, Rp87.725.158,- for profit and Rp578.986.000,- for the sale price. The result using JOC with full costing approach is greater than that of the firm of this difference due to differences in the way grouping and incremental costs are incorporated into cost of goods manufactured calculations using the full cost JOC method. Cost of goods manufactured calculated on the basis of the company is undercosting. The test results of 22 orders with the t test get the value of Sig. (2-tailed) = 0.00 <0.05 so it shows a significant difference between the value of cost of goods manufactured, the profit and the selling price set by the company with the value using the JOC approach full method costing.
