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

Water demand is the amount of water required to support human activities. Along with the growth ofJemara Island comunity, water has became one of the primary need to obtain a better and productive life.According to the survey that has been carried out, Jemara Island community still have not had access for cleanwater and electricity to accommodate the community need. Based on the results of field survey, Jemara Islandcomunity rely their water need on seven dug wells with diameter of each well of 1,5 meters and depth of 3meters. However, at high tide, the well near to residential will be affected. It causes Jemara Island communityrely in their water supply on the well 10 meter away from the residential which spend lot of energy. Therefore,this service community program will optimize two wells located far from the shoreline at the top of thetopography, provided water pump to drawn well water, provide water reservoir and also install pipe waterdistribution to the residential. According to a study that has been carried out, to drain water into two reservoirswith a capacity of 2,500 liters, the pump is able to operate for 6 hours with 2 hours pause after used to avoidpump perform over the daily usage limit. In order to pump water to the reservoirs, it needs 6 liters gasoline tooprate the pump and generator set. Assuming that each resident consumes 10 liters of water per day with apopulation of 150 people, then the need for clean water for drinking or cooking is 1500 liters, so it is estimatedthat two tandons will be used for about 4-5 days.

Abstract

In shipbuilding, various stages of surveys are conducted when a vessel is declared fit for operation, encompassing annual surveys, intermediate surveys, and special/extension surveys. During these surveys, commonly encountered issues include corrosion and reduction in plate thickness associated with the ship's age and year of construction. In cases of significant thickness reduction, replating procedures are implemented. The examination of plate thickness involves ultrasonic testing utilizing the Cygnus Ultrasonic Gauge, with prior visual inspections performed on each plate section. When inspections reveal considerable thickness reduction and indications of corrosion during visual tests, such instances are evident in areas like the forepeak and deep tank. Substantial thickness reduction is noted on both the port and starboard sides, covering a dimension of 1,200 mm × 400 mm along each plate line, employing standard 12 mm thickness material. Test results are obtained for plate lines numbered 1 to 4 on the port and starboard sides of the Forepeak Tank area, as well as plate lines numbered 1 to 3 on the port side and plate lines numbered 1 to 4 on the starboard side within the Deep Tank region.
