Abstract

ABSTRAK Selama ini penentuan block belum ada dasarnya hanya mengandalkan pengalaman semata. Didalam latar belakang ini perlu dilakukan perhitungan berapa jumlah block yang optimal untuk dimensi kapal yang berbeda berdasarkan safety factor yang ditentukan untuk kapal tertentu. Dilakukan penentuan dasar dengan variasi beban-beban dengan software solidwork untuk mengetahui yield strength maka dilakukan hubungan grafik antara beban yang dialami oleh material dan hasil yield strength. Setelah itu ditentukan safety factor yang diinginkan maka dihasilkan hubungan yield strength dengan safety factor. Kemudian hasil yield strength dari safety factor tersebut maka didapatkan beban maksimal yang diterima oleh material. Selanjutnya diketahui displacement kapal dari hasil perhitungan dengan rumus pendekatan. Setelah diketahui displacement kapal, maka didapatkan hasil jumlah block dengan safety factor tertentu. Dari hasil analisa tersebut jenis material ini memiliki hubungan tegangan maksimal dengan safety factor tertentu, maka besarnya safety factor 1 mampu menerima beban sebesar 17,5 ton, dengan safety factor 1,5 mampu menerima beban sebesar 11,5 ton, dengan safety factor 2 mampu menerima beban sebesar 8,5 ton, dengan safety factor 2,5 mampu menerima beban sebesar 6,7 ton, dan yang terakhir dengan safety factor 3 mampu menerima beban sebesar 5,6 ton. Kata Kunci : Dock Block, Docking, Reparasi ABSTRACT So far there has been no determination block basically just rely on experience alone. In the background is necessary to do the calculation of how many blocks are optimal for different dimensions of the vessel based on the safety factor specified for the particular vessel. Is the determination of the base with a variety of loads with solidwork software to determine the yield strength is carried relationship graph between the load experienced by the material and the results of yield strength. Once it is determined that the desired safety factor, the resulting relationship with yield strength safety factor. Then the results of yield strength of the safety factor then obtained maximum load received by the material. Furthermore, known displacement boat from the calculation of the formula approach. Once known displacement vessel, then showed the number of blocks with a certain safety factor. From the results of the analysis of this type of material has a maximum voltage relationship with a certain safety factor, then the magnitude of the safety factor 1 is capable of receiving a load of 17.5 tons, with a safety factor of 1.5 is able to receive a load of 11.5 tons, with a safety factor of 2 is able to receiving a load of 8.5 tonnes, with a safety factor of 2.5 is able to receive a load of 6.7 tonnes, and the latter with a safety factor of 3 is able to receive a load of 5.6 tonnes.
