Abstract

The hydraulic system has been widely used for various tools. The system developed from Pascal's law becomes one of the vital knowledge that its use in the industrial world. Ranging from small businesses to some kind of a car wash with large industries such as molding machine. The components are arranged in the hydraulic cylinder includes a tube, piston, rod axles, gland, and seal. Each component has the function and role of each and every component seal types are also different types, for a material component of the hydraulic cylinder must not rustproof for hydraulic oil in addition to the driving also serves to lubricate the hydraulic cylinder components. The greater the pressure in the hydraulic tube is getting thicker the hydraulic tube wall, so that the seal does not leak type of profile and material must be in accordance with the state of the hydraulic cylinder, for the connection technique in the hydraulic cylinder components should also be considered such as when welding, welding wire material must be in accordance with the material to be welded. For the methods used in the design of the hydraulic cylinder on the rubber molding machine is an analytical method burdened straight column in the center of axle rodmethods MAWP (Maximum Allowable Working Pressure) to force the tube The results of this design is for a straight column burden in the short-sized center, and to the strength of the tube can withstand the pressure 607.74 bar as well as the costs required to make the hydraulic cylinders in rubber molding machine is very affordable.

Abstract

PT. XYZ is a company engaged in the production of labeling for food and beverage products, fire cases in other factories, reminding the owner to keep his assets safe and comfortable. So it is necessary to plan and design Fire Fighting System to protect the building and its assets. So it is necessary to plan and design Fire Fighting System to protect the building and its assets. This research begins with taking and collecting data in the form of layout of old building condition and layout of new building condition and other technical data needed. Data processing conducted refers to SNI 03-3985-2000, SNI 03-3987-1995, SNI 1745-1989-F, NFPA 13, NFPA 10 and NFPA 14 standards, including design of sprinkler, hydrant and APAR systems (Fire Extinguishers Lightweight) is required, calculate the need for fire water, calculate the total head and pump power required. Based on the result of the research, it is found that the building is classified as light fire hazard and designed using sprinkler type of wet pipe system and the required sprinkler head count is 130 pieces with temperature sensitivity of 57 °C orange glass bulb color, direction emission down, building hydrants as much as 1 piece, page and city hydrants as much as 1 piece, 15 types of dry chemical APAR type and type APAR (CO2) as much as I fruit. The volume of water supply needed for the fire-fighting system is 150 m3. The pipe used is a type of cast iron pipe with total head at the pump of 71.748 meters. The calculation of pump capacity in this planning is 11,576 hp and the originator 14,622 hp.
