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.
There are still fishermen using Anco as a fishing gear by carrying it, and walking along the river, greatly affecting the health of fishermen, especially for feet that are too long submerged in water, as well as limited fishing grounds. This obstacle can be overcome by using a simple, inexpensive and reliable floating tool for coastal areas, rivers and shallow and not fast-flowing mangrove forest waters. So it is necessary to do research to be able to realize floating tools that are in accordance with the conditions of the waters. The floating tool research activity is expected to be beneficial for the coastal communities of deesa Bedono, Sayung Subdistrict, Demak Regency, Central Java, especially to increase the fishing yield and welfare of the fishing community. The analysis results of the floating appliance ability receive loads up to 300 kg / drum so that the capacity of 1 tool module can be planned for 3-4 people. With affordable costs, it can be applied to the community.
Untuk kelancaran pengoperasian Oily water separator, perawatan dan perbaikan harus dilakukan secara berkala agar tidak mengganggu pengoperasian kapal. Tujuan artikel ini adalah untuk menganalisis unjuk kerja mesin Oily Water Separator tipe CYF-1.OY pada proyek pembangunan kapal 2000 GT. Metode Eksperimen yang digunakan untuk menentukan kinerja mesin dan mengasumsikan pendekatan koreksi penilaian. Hasil dari performa mesin, waktu kerja mesin berbanding lurus dengan volume kapasitas sampah sehingga semakin banyak volume maka waktu yang dibutuhkan semakin lama tergantung. Efisiensinya hampir sama artinya hasil di bawah 5% dan masih dalam relevansi. Dalam pengoperasian dan penyetelan Oily Water Separator diperlukan pengamatan dan perhatian yang lebih, terutama untuk tampilan dan kapasitas spesifikasi mesin.
<p><em>Seiring dengan perkembangan teknologi yang semakin pesat di dunia pelayaran, ia telah menciptakan banyak metode terbaru yang ditemukan. Baik dalam sistem pengembangan, dan sebagainya. Metode pengembangan yang digunakan dalam proses pembuatan kapal sangat berpengaruh dalam memperkirakan penyelesaian pekerjaan, biaya yang dikeluarkan, dan hasil kualitas yang baik. Dalam metode pengembangan ini ada beberapa proses yang harus dilewati dalam proses salah satunya adalah proses Penggabungan Blok (Joint Erection) yang dilakukan untuk mengkoneksi dengan blok balok lain menjadi satu bagian kapal yang utuh. Dalam proses Joint Erection proses Fit Up yang dilakukan sangat penting untuk mendapatkan koneksi antar blok yang baik dan benar. Fit Up adalah proses koneksi dua blok menjadi satu salam suatu parameter. Dalam proses pembangunan Kapal Patroli Kelas-A2-55 meter menggunakan metode sistem blok sehingga proses Fit Up diperlukan dalam pengembangan ini untuk memenuhi standar dan kualitas yang diinginkan. Dengan metode pengembangan yang lebih cepat dan mudah itu akan berdampak pada kepuasan setiap pelanggan terutama di dunia pelayaran.</em><em></em></p><strong></strong><em></em>
