Abstract

Docks at the shipyard company have the potential danger due to failure in the ship shocks. It causes damage to the ship and accidents on ship repair and maintenance work because the entire weight of the ship fully rests on the docking blocks. One of the reasons for the failure of the docking blocks is the error in the selection of materials used, so it is not strong to support the ship hull on it. Therefore, this research was conducted to provide recommendations for docking block wood type for docks at shipyards. Recommendations are made by comparing the wood used today with the wood that has a higher strength level according to PKKI 1961 and making comparisons with SNI 7973-2013 regarding design specifications for wood construction to determine the mechanical properties of each wood. Mechanical property values are used as material properties for loading simulation using Ansys software. There are three observed parameters: von mises stress value, total deformation and safety factor. Based on the results, the strongest and the safest woods for docking blocks are Ironwood, Bangkirai wood, Meranti wood and tamarind wood, respectively.

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

Proyek struktur Rom Bin merupakan struktur yang dipesan oleh perusahaan pertambangan diBanyuwangi dengan tonnage 76,47 ton. Rom Bin merupakan suatu struktur yang dibangun denganspesifikasi material khusus karena di pesan dengan fungsi yang fokus pada kekuatan dan lamawaktu pemakaian. Dengan spesifikasi tersebut tentunya mengakibatkan perbedaan perlakuan danlama waktu proses pengerjaan. Sehingga diperlukan suatu sistem penjadwalan yang tepat agarproyek dapat berjalan dengan tepat waktu dan biaya.Proses penjadwalan pada proyek akanmenjadi lebih akurat apabila menggunakan metode PERT. Ketidakpastian waktu pengerjaan proyekdicerminkan dengan tiga estimasi yaitu durasi optimis (to) , most likely (tm) dan durasi pesimis (tp).Dan dalam penggunaanya digunakan nilai rata-rata (te) dari ketiga cerminan waktu tersebut untukmenentukan umur proyek serta pembuatan kurva probabilitas. Dari nilai rata-rata durasi tersebutpula akan dilakukan analisa menggunakan crashing terhadap waktu optimum pengerjaan proyekdengan menggunakan konfigurasi penambahan jam kerja (man hours). Hasil analisis waktupengerjaan proyek menggunakan metode PERT adalah 174 hari dengan biaya Rp. 370.355.800,-.Untuk mendapatkan suatu proyek memiliki nilai yang tepat waktu dan biaya maka dilakukanperhitungan optimum menggunakan metode crashing dengan konfigurasi penambahan jam lemburyang menghasilkan waktu optimum proyek selama 154 hari dengan total biaya Rp. 359.208.356,-.

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.
