Abstract

Perbaikan dan perawatan kapal merupakan proses yang dilakukan pemilik kapal agar kondisi kapal yang diunakan selalu dalam kondisi prima. Masyarakat pesisir melakukan perbaikan kapal berdasar atas pengalaman yang biasanya diperoleh secara turun temurun. Dalam proses tersebut banyak masyarakat yang kurang peduli dengan resiko keselamatan dan kesehatan kerja. Hal ini bisa terjadi karena msyarakat sering berikir bahwa selama ini kegiatan tersebut tidak masalah sebab mereka tidak pernah sakit. Dengan kurang awamnya masyarakat terhadap masalah tersebut maka perlu diberikan sebuah penyuluhan serta langkah aman dalam melakukan perbaikan kapal yang pasti akan mereka lakukan.

Abstract

The need for personal protective equipment (PPE) in the form of face protection has increased sharply since the spread of the covid19. Viruses that can be transmitted through droplet media can endanger health or personal who interact directly with sufferers of diseases caused by covid19. The existence of a face shield, even though it is not the only one protective device, is needed to support other equipment. Without the face shield, it will increase the likelihood the transmission of virus. The purpose of writing this journal is to explain the process of design, manufacture and planning of PPE distribution to the public From the process carried out it can be concluded that the production process goes through several stages involving human resources with product design, managerial, packaging ability and also diverse tool resources including pneumatic, CNC machines, laser cutting and computer. In terms of distribution, delivery of equipment is carried out using a variety of land, sea and air expeditions with location areas in several provinces including Central Java, East Java, West Java, West Sumatra and Riau Islands.

Abstract

The character of the ship's hull will determine the speed and movement of the ship. Ship engine power to overcome resistance is influenced by the hull of the ship so that in doing the design it is necessary to calculate precisely. This research is a further study related to the installation of wireless control devices and the design of unmanned hulls but with a different hull and engine shape. The conclusions obtained from this study are the main size of the ship are as follows: LWL = 66.74 cm; B = 32.07 cm; T = 4.91cm; Cb = 0.338. The ship has pre planning at speed: 2.5 - 4.75 knots with 6.09 – 19.6 N resistance and froud number values between 1.028 – 1.952, then experience planning at a speed of 3.5 knots with resistance values starting at 5.59 N with froud number starting at 1.439. To reach the speed of 10 knots, the ship needs around 102 W of power. The object of the ship investigated above is the Batam State Polytechnic Gurindam ship, where the ship was once used for the national fast boat contest in Indonesia. Hopefully with this research, it can provide a knowledge related to the resistance that occur and, in the future, will be used as the basis for the development of the ship to be better designed.

Abstract

A Pressure Vessel is a container for storing liquid and gas fluid shaped like a cylinder that can produce pressure from outside or inside. Almost all oil and gas industries often use this object to collect and separate water and oil from offshore exploration. This study aims to determine the strength of a Pressure Vessel and determine which is more economical by comparing two types of materials, namely SA-106 Grade B and SA-516-70N, with the same thickness of 12.7 mm. Simulations are carried out on the shell using SolidWorks software to find out the strength of each material. The data used in this study refer to one of the Pressure Vessels from the company with the basic design following ASME section VIII Div.1 standard 2007, document name "Cartridge Filter C027-S-U13000-01 A / B" and document number 6522 -XXX-C027-ISGP-U40300-MX-4018-00XXX with a design pressure of 10 bar, a design temperature of 121 ° C, an inner diameter of 444.5 mm, a corrosion factor of 3 mm. From the calculations and simulations that have been carried out, the values ​​obtained from the maximum pressure on the SA-516-70N material are 34.10 Bar, and the SA-106 Grade B material is 16.90 Bar. The voltage received from the pressure vessel is based on the analysis of the SolidWorks software with the same value for both materials at 1758 psi / 121 Bar. This study also proved that SA-106 Grade B material is far more economical, with an estimated budget of Rp6,531,951 for one 10m long pipe.

Abstract

This study aims to test the performance of the Batam Marine Ambulance model as a medical and logistics support fleet using the comparison ship method. A series of stability and motion analysis processes were carried out, then the results were assessed to determine the best design among the proposed design options. Performance tests used three ship models (Model I, Model II, and Model III). It is known that in the stability test, the tilt angle of model III is 33.63° and the maximum GZ value is 4.673 cm. Then, in the resistance test, Model I has a lower resistance of 87.29 N and the required power is 1496.93 W compared to the other proposed models. In the seakeeping test, Model III was found to be more stable or less affected on all surface conditions because the RAO value was relatively lower, namely 90o in terms of heaving, rolling, and pitching at 135o and 180o then had lower additional resistance. The Model III design has good ship stability, drag, and seakeeping characteristics.
