Abstract

Lovina Beach, which is located in Buleleng Regency, Bali Province, is very attractive to tourists because it presents the attraction of wild dolphins in the middle of the sea. The dolphins on Lovina Beach are protected by local government regulations, so no one is allowed to catch or sell them. To be able to watch dolphin attractions in the middle of the sea, tourists must rent a boat that has been provided by the manager. Boats that sail using diesel fuel are quite expensive. These conditions are the background to serve this article. We develop solar cells as an alternative energy fuel for boat propulsion. Solar cell is a device or component that can convert sunlight energy into electrical energy using the Photovoltaic effect principle. The photovoltaic effect is an earthquake phenomenon where the voltage is due to the contact or contact of two electrodes which are served with a solid or liquid system when receiving light energy. The electrical energy that is processed is stored in the battery which will be used while sailing. The advantage of solar cells is that they are environmentally friendly and do not cause pollution at all, and solar cells are a source of energy considering their sustainable nature (renewable) and abundant instructions. Keywords: Boat, diesel fuel, solar cells.

Abstract

The diesel engine as the main engine on the ship can function properly if it is supported by good supporting systems such as a lubricating oil system. The lubricant system is one of the most important systems in ship operation, failure in the lubrication system causes the system to not operate properly and can suffer losses from the ship. This study aims to determine the failure of each component of the lubricating system in the main engine and its proper maintenance. This study was conducted using the Failure Mode and Effect Analysis (FMEA) method to optimize the way to overcome the failure and maintenance of the ship's main engines to identify strategies and maintenance priorities. By using FMEA, we can determine the failure and the effect caused by each component and to perform maintenance must classify components based on low to high risk levels. The components of lubricating oil tank and sump tank have a low risk, lubricating oil cooler has a moderate risk and lubricating oil pump, lubricating oil filter, purifier, transfer pump and lubricating purifier heater have a high risk. The results of the failure of lubricant system components are very useful in identifying maintenance strategies based on the level of risk of these components by choosing between preventive maintenance and corrective maintenance.

Abstract

Tank is a cargo storage container and is the main part of ships carrying liquids and gases so that the cargo is maintained and safe. As a storage medium, the tank will always get loads that come from inside as well as loads that come from outside the tank, sloshing is one of the loads that come from inside. Sloshing occurs due to the movement of the vessel/tank resulting in free motion of oscillating fluid hitting the tank wall. The purpose of this study was to find the effect of the load on the movement and sloshing load on the tank with variations in the amount of load. The tank model used is a reference to a general purpose tanker transporting crude oil in two-dimensional rectangular conditions (midship) with a width of 8,6 m and a height of 8 m on both the left and right sides. The variations used are 10% load volume (0,8 m high), 30% volume (2,4 m high), 50% volume (4 m high), 70% variation (5,6 m high) and 90% variation (high 7,8 m). The simulation was carried out with a numerical method, namely Computational Fluid Dynamic (CFD) using Ansys Fluent software. The back of the tank is based on the movement of the ship which in this case is limited to heaving and rolling motion, from the simulation results it is concluded that the biggest sloshing effect occurs at the load volume variation of 10%, the frequency is 2.145, while the greatest pressure occurs at the lower left corner of the tank with a pressure of 443,29 Kpa.

Abstract

Barge or Barge 5000 DWT is a means or means of sea transportation that contains coal. PT Maritim Transportindo is engaged in the shipping transportation industry, which provides barges to transport coal. Based on these problems, a redesign of the oil barge will be planned according to the BKI class standards. The results of planning using the standard empirical calculation method of BKI Vol II 2016, the results of the design of the load space obtained 5 loading spaces with each size of loading space, namely loading space 1 and 2 obtained 10,980 mm in length, 3 and 4 load spaces obtained 12,810 mm in length. , load space 5 is obtained 10,980 mm in length. Based on the planning of the loading and unloading system, the pump for loading and unloading system has a planned pipe diameter of 125 mm with a capacity of 2 main loading and unloading pumps, namely 218,382 m3 / hr with 2 hours of main pump power 14, 12 Kw. The capacity of the loading and unloading standby pump is 109.191 m3 / hr with a pump power of 7.0628 Kw.

Abstract

General cargo ship is a ship that carries various kinds of cargo in the form of goods. Goods that are transported are usually packaged goods. General cargo ships are equipped with cargo cranes to make loading and unloading easier. In this design the hull design is planned. The main size of the ship was obtained using a regression comparison method based on data from 2 comparison vessels obtained from the Korea Register of Shipping (KRS). From the main dimensions obtained, a line plan and hydrostatic analysis is carried out according to the IMO standard. From the planning results obtained for ships with a capacity of 17000 DWT obtained ship dimensions with length over all (LOA) 153.45 m, length between prependiculars (LBP) 144.24 m, Length on load waterline (LWL) 147.85 m, width (B ) 25.27 m, height (H) 13.5 m, loaded (T) 9.52 m, speed (Vs) 14.75 knots, block coefficient (Cb) 0.7, midship coefficient (Cm) 0.79 , waterline coefficient (Cw) 0.81, horizontal prismatic coefficient (Cph) 0.91, vertical prismatic coefficient (Cpv) 0.89, volume 25520.5 m3. This comparison ship method makes it easy for ship designers with accurate results.

Abstract

Lifting tools are aircraft or tools used to lift or move an item with a certain distance, size and weight. Gantry Crane is a type of tall upright portal crane that lifts objects with a hoist that is mounted on a hoist trolley and can move horizontally on rails or rail pairs attached to beams or work floors. The Kijing Terminal is a development of the Pontianak Port and is one of the National Strategic Projects (PSN). Gantry Crane Type ECT-15 indicates that the maximum and minimum carrying strength of the Gantry Crane ECT-15 Type must be adjusted to the size of the tool. The data obtained is very accurate, such as the height of the tool is a maximum of 12 m capable of lifting goods from a minimum of 1-14 tons where the lifting speed is 6/20 or 4.5 / 15, can cross 18 / 1.8 or 12 / 1.2, ending the transport of 20 / 1.5 or 30 /2.2 where the quantity to be transported or the dimensions transported N 83 R between 1000 or 1300, wheel diameter 500-630. The Gantry Crane ECT-15 T container has advantages such as strong lifting capacity, excellent design and simple structure. In addition to having the advantages of a Gantry Crane, it also has disadvantages including: Requires Clearance Area, Safety Supervision must be tighter, and more intensive maintenance (outdoor).

Abstract

Shipbuilding nearly 2/3 of the work is welding work. There are several variations of the weld joint as an option based on the thickness and quality of the material, the method of welding. Welding results generally depend heavily on the skill of the welder. Weld damage both on the surface and on the inside is difficult to detect with a simple test method. In addition, because the structure being welded is an integral part of the entire body of the weld material, the cracks that arise will spread quickly and may even cause serious accidents. In general, welding on ships has requirements from the Classification Agency which supervises and provides the feasibility of the ship's construction strength. To meet these requirements, the role of the welder and technique is very large, so that the ship gets good welding quality and can be accepted by the shipowner and the classification agency.
