Abstract

Based on statistical data in recent years, there are still quite a number of ship accidents due to fires, including on passenger ships. The water mist system is a fire suppression system that allows it to be used in the engine room with the advantage that it can keep the heat production rate low during the extinguishing process and can be operated earlier than the CO2 system. The research is conducted by using fire dynamic simulator in the engine room of a 300 GT ferry ro-ro passenger to compare the heat release rate of fire without an extinguishing system, an existing CO2 system, and a water mist system. The result shows that the CO2 fire suppression system reduces the heat release rate more rapidly to the decay phase at 375 seconds while the water mist takes more than 900 seconds. However, the fully developed phase of the water mist suppression system occurs more quickly than CO2 because the sprinklers are activated shortly after a fire occurs. Unlike water mist, the CO2 system is activated at 60 seconds so that the pre-combustion, growth, flashover, and fully developed phases are at the same HRR and time as the natural one.

Abstract

currently general cargo transportation using containers is preferred. There are many reasons for choosing a container compared to normal cargo transportation, some of the reasons are having a standardized protection system, so it is safer to protect cargo. On the Samarinda - Kota Bangun route, transportation for logistics distribution uses the truck transportation mode. In this mode of transportation, it is highly influenced by traffic conditions and the roads in which it passes. For this reason, the use of self-propelled container barges (SPCB) is considered very efficient because it can overcome problems in container transportation rather than using land transportation modes. To get the design of a self-propelled container barge ( SPCB) the main size of the ship is obtained from the ratio of the main size of the ship. Then make a Line Plan with Maxsurf software and make a general plan with Autocad software and the main measurements obtained are; Lpp = 83.7 m; Lwl = 87.04 m; B = 12 m; H = 6 m; T = 4.5 m; VS = 10 knot; D = 4383 ton. With the number of containers as much as 140 Teus, the largest trim occurs at 0% DWT, namely 0.611 m stern trim. All the stability criteria of IMO A 749 (18) meet the 4 variations of the weight of the ship. In the DWT condition 100% the GZ max value is 0.512 m at an angle of 27.3○, and in the DWT condition 50% the GZ max value is 1.717 m at an angle of 38.2○ and at 25% DWT condition the GZ max value is 2.454 m occurs at an angle of 40.9○, and at 0% DWT condition, the maximum GZ value is 2.674 m occurs at an angle of 25.5○.

Abstract

Currently in Indonesia, the need for maximum service in terms of passenger transportation on ships needs to be increased in order to compete with other modes of transportation such as airplanes and trains. The lack of customer satisfaction is caused by several factors such as the condition of the facilities and the comfort of the passengers on the trip. The quality of the facilities and services of the passenger ship can be improved by redesigning the interior of the public facilities and accommodation space for the passengers of the ship. The interior design is carried out to increase public interest in using the services of the ferry. Based on the results of a survey of ship passengers' opinions, it is known that passenger comfort can be improved, especially on the factors of cleanliness, room arrangement, air circulation, rejuvenation of the room as well as interior visuals that are made more attractive. The result of conceptualizing and designing the interior of the ship is that it is necessary to have an interior design that is popular with the public, has its own characteristics, attracts public attention, and is simple and not shabby design. The design concept that fits the needs above is the Avant basic concept because this design theme is a translation of current design trends and presents its own characteristics for the ship. Interior rearrangements and furniture adjustments were made according to the activities on the ship and adjusted to the passenger comfort factor according to marine standards while taking into account the statutory regulations.
