Transportasi laut menjadi penghubung kebutuhan dan perekonomian antar pulau di Indonesia, daya angkut dibuat seoptimal mungkin untuk dapat menyuplai kebutuhan masyarakat. Kapal yang ditinjau adalah jenis kapal barang peti kemas. Perencanaan bentuk lambung kapal dipengaruhi oleh beberapa faktor diantaranya adalah dari segi kegunaan kapal yang akan dibangun. Dari perhitungan hambatan dapat diketahui berapa Trust Horse Power sehingga dapat digunakan untuk menghitung efisiensi propulsi kapal. Kapal harus memiliki propulsi untuk melawan seluruh hambatan yang mungkin terjadi pada lambung kapal. Dari hasil analisis kapal barang peti kemas dengan kapasitas 100 teus memiliki daya mesin sebesar 1530 HP dengan sistem penggerak ganda dengan peletakan kamar mesin berada di belakang kapal. Tipe baling-baling yang di rencanakan adalah fixed pitch propeller B - 4. 40  , dengan bahan material bronze . Ukuran pitch daun baling-baling 1650 mm dengan diameter baling-baling sebesar 1850 mm.

In a ship planning can not be separated from the planning of the ship launching process. A ship can glide perfectly if it has a high enough planning time and costs. The launch process itself is divided into several ways. The choice of this method needs to be considered because it relates to the budget and preparations made. The method used is the calculation according to the numerical approach assisted by computational software. In the first calculation it is planned with the slipway launch, and then the next one is planned with the airbags that have been implemented previously. The purpose of this study is to provide analysis results as a consideration in implementing the slipway and airbag ship launching method on KM ships. Belt Nusantara 72 measuring 2000 DWT. In steps 5 to 6, both the slipway and the airbags experience a stern lift condition with a value (yVd) of 1396.97 ton.  Based on the economic analysis of the hours of people using airbags, there is a decrease in working hours by 44% when compared to the launch using a slipway. This also happened to work productivity where it was 84% more time effective. When viewed from an investment point of view, the use of slipways is actually more economical than airbag, the difference is 43% more economical using slipways. Both types of launch can be applied by looking at the economical side and the ability of each shipyard in carrying out the launching process and seeing the main size of the ship to be launched.

Develop of fishery port area in the Semarang city, therefore need improve for a fishing vessel design that inaugurated the representative of the port area Tambak Lorok. The vessel was also not equipped with hydrostatic calculations, stability and so on, then most fishermen in Indonesia use wood as a material for the creation of fishing vessels. The purpose of this research is to get design criteria and dimension of fishing vessel and determine the construction design criteria of the right fishing vessel performance in the Tambak Lorok sea area Semarang accordance with IMO (International Marine Organization) standard. Designation of the method as the efforts to produce optimization design output and meet the various criteria required with comparison method using the 5-size main ship dimension, as well as for the design and calculation of criteria with ship design software. This design method requires average size comparative vessel capable of developing and influence the size and speed of 5 GT ship model. The results this design method requires a comparative vessel capable of developing and influence the size and speed of 5 GT ship model. Analysis results of designing fishing vessel show the development of best ideal size on 5 GT ship class to operate in the cruise area shallow water. Practical stability and resistance diagrams to predict ship performance and provides the prediction procedure showing how to develop such diagrams using the available main dimension ship data.

On the process of constructing ships with the block system has a tendency to dealing time production process for assembly. The waiting time makes the construction of the bottom plate to receive the burden during the waiting time so that the deformation often occurs due to excess stress received. The purpose of this study to know the stress value of the bottom construction of a block due to the static load on the ship building process. The method used is the Finite Element method is a form of the approximation method commonly used to solve an equation numerically in a stress analysis. The variables used in this study are the different types of meshing, the number of focuses on stop block. Based on the results start of the construction stress analysis Plate Bottom block B-03 on the construction of patrol ship. Obtained the highest stress value in the use of 4 stop block so, it is advisable to increase the number of stop blocks in order to reduce the results of excessive deformation.
