Abstract

Ship recycling pays attention globally as it becomes a need for sustainable development. Industrialized countries begin to move ship recycling activities to develop nations where labor is paid cheaply, and safety and environmental issues are not as strictly enforced. This challenge is mostly the effect of high costs as it occurs in a standardized process. This paper aims to identify a design of a cleaner production concept to improve the ship recycling model, where the negative impact caused by ship recycling needs to be minimized immediately through a sustainable approach. In order to convert ship dismantling into Green Ship Recycling, there are several ship recycling regulations that can be used as standardization and development that must be carried out based on guidelines related to technology and facilities, material handling, worker and environment safety, ship recycling plans, and the layout.

Abstract

traditional fishing boats are used by fishermen for finding fish to support their daily lives. Because there are many shortcomings in their boats (design problems) and natural conditions that often change, accidents can occur which cause their boats to easily overturn and sink to the bottom of the sea. Other problems were also encountered, such as the boat's obstacles, and the boat's floating compartment was not well designed. For this reason, the author conducted research on the design of a fishing boat with a floating compartment using the BKI rules. Using one of the existing boats was made as a design reference with boat sizes. The principal dimension of the fishing boat is LOA: 10.15 m, Lwl: 8,996 m, B: 1 m, H: 0.87 m, H: 0.3 m, and 2 GT. The results of the calculations find that the engine specification that suits the fishing boat is 3.5 kW with a speed of 7 knots. The author's research varies the Floodable Length of the original boat's floating compartment with a compartment size of 1.365 m AP, 1.325 m FP, and model 2 floating compartment using BKI rules with AP size 2.225 m and FP 2.425 m. The analysis result based on the design of the fishing boat shows that model 2 is the best design. Construction in accordance with BKI regulations, a mixed type of construction was chosen. The frame distance is 500 mm with the stiffener type model h = 25 mm, bb = 30 mm, and bc = 36 mm. Meanwhile, the total stringer is 6 stiffeners.

Abstract

The propeller is an important part of determining the ship's maneuverability. The propeller itself is a tool to produce thrust that comes from engine power which is transmitted through the shaft. At their defined radial position, Propeller thrust (N) and torque (Nm) are formed from propeller blade foil sections at the local lift and drag. Particularly, the total propeller thrust will be integrated into an axial lift vector for the sections from root to tip. The selection of a good propulsion device will affect the force of the ship. One way to choose the propulsion of the ship is the selection the type of propeller and the provision of new propeller variations to produce maximum thrust. For that reason, this study aims to analyze of thrust and torque of B-series propellers using CFD by varying the number of blades: 3, 4, and 5 blades; and the propeller speed (nProp) i.e., 325, 525, and 725 rpm. The numerical analysis using computational fluid dynamics (CFD) was conducted to identify the thrust (N) and force (Nm) of the propeller. The CFD simulation consists of three main steps: pre-processor, solver manager, and post-processor. The results show that the thrust and torque significantly increased at the higher number of blades and nProp.

Abstract

This study analyzes co-flow as active flow control in the object of the airfoil. NACA 0015 is the airfoil used in this study. The airfoil was then modified to add co-flow jet features. Co-flow jet was placed on the upper chamber to analyze its effect on airfoil performance. Further, the Co-flow jet was studied by varying the injected mass flow rate () in the injection slot. The variation of  is 0.15, 0.20, and 0.25 kg/s. The study used CFD with the governing equation RANS. Reynolds Averaged Navier Stokes combined with turbulence model to solve all equations. Two equations for the turbulence model are used in this study. Specifically, this study discusses the aerodynamics of the airfoil, i.e., lift force, drag force, and fluid flow visualization, such as pressure contour and velocity contour. Co-flow jets can improve the aerodynamics of airfoils. The bigger the  injected, the higher the lift coefficient increases. On the other hand, the drag force will be reduced as the number of injected fluid flow increases. Because of that, the airfoil efficiency will be better if using a co-flow jet. However, the Cl/Cdcurve peak shifts to smaller as the injection fluid flow are bigger. The fluid flow visualization by velocity contour on AoA=20° revealed that the co-flow jet could overcome separation.

Abstract

Improvement of the performance of the diesel engine can be done by expanding the combustion chamber. One of the objectives of this research is to obtain optimal piston performance by modifying the piston crown to be 1mm deeper than the standard piston using B30 fuel. This research is also proof of previous research with a simulation that concluded that the performance of a diesel engine using a modified toroidal combustion chamber (TCC) +1mm piston has better performance than a standard piston. This research will analyze the comparison of the performance of a diesel engine using a standard piston and a modified piston on the diesel engine, using an experimental method with B30 biodiesel fuel with engine speed (RPM) variation of 1900 and 2100, also the dummy loads used are 1000, 2000, 3000, and 4000 Watts (W). From the results of the performance tests, it is concluded that the standard piston produces better performance than the modified piston with a very small difference in value in terms of torque, power, and SFOC. The level of NOx emissions produced by the standard RPM 1900 with 1000 W load is 1,483 g/KWh, at a load of 2000 W is 1,011 g/KWh, at a load of 3000 W is 1.375 g/KWh, at a load of 4000 W is 2,372 g/KWh, for standard piston RPM 2100 NOx emission levels produced at 1000 W load is 1,902 g/KWh, at 2000 W load is 1,450 g/KWh, at 3000 W load is 1.368 g/KWh, at 4000 W load is 1,066 g/KWh. The level of NOx emissions produced using a modified piston at 1900 RPM at 1000 W load is 1.865 g/KWh, at 2000 W load is 1.326 g/KWh, at 3000 W load is 1,250 g/KWh, at 4000 W load is 0.857 g/KWh, for RPM 2100 uses a modified piston at a 1000 W load is 1,970 g/KWh, at a 2000 W load is 1,583 g/KWh, at a 3000 W load is 1,465 g/KWh, at a 4000 W load is 1,226 g/KWh. NOx emission levels using standard pistons at RPM 1900 with B30 fuel tend to be smaller at low loads and larger at high loads compared to modified pistons, while NOx emission levels using standard pistons at RPM 2100 fueled by B30 are smaller than using a modified piston.

Abstract

LCT conversion passenger ships have been widely operated in the waters of the Bali Strait. Ship operations in the Bali Strait result in repeated loads on the structure. Repeated loading produces vertical and horizontal bending moments that act randomly due to waves. Based on this, it is necessary to analyze the structure of the ship. The purpose of this study was to analyze the reliability value of the ship structure operating in undulating waters. Wave analysis is performed using the spectral method to determine the value of the load acting on the ship, while the reliability calculation uses the Mean Value First Order Second Moment (MVFOSM) method to determine the reliability value. The analysis was carried out on a full load and an empty load. The value of the reliability of the structure at full load is 0.913615 and at empty load is 0.88948.

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.

Abstract

One way to reduce the scarcity of fuel oil is to make environmentally friendly alternative fuels such as biodiesel. The utilization of biodiesel can be a new energy source and also help reduce the excessive use of fuel, especially diesel and diesel oil in Indonesia. In Indonesia, the amount of palm oil will reach 49.7 tons by 2021, and this data is up 2.9% from the pre-vious year. Palm fruit is processed into CPO. More palm oil processing will produce waste called POME (Palm Oil Mill Effluent). The diesel engine transesterification method is suitable for the manufacture of biodiesel. The amount of base on the catalyst's surface affects the catalyst's activity. So that the higher the base value on the catalyst, the higher the yield of biodiesel that will be produced. The biodiesel produced will be tested on a 4-stroke diesel engine with a B5 and B10 blending composition. The study's results showed that the density and viscosity values for B5 were 5.8 cSt and 810 Kg/m3 and for B10 were 6.3 cSt and 860 Kg/m3. As for engine performance, power, torque, and SFC for B5 fuel at 4000-watt load conditions and 1000 Rpm, engine speeds are 1.18 Kw, 11.28 Nm, and 256.8 gr/Kw. B10 at 4000-watt load condition and 1000 Rpm engine speed is 1.16 Kw, 11.12 Nm, and 269.2 gr/Kw.

Abstract

The fishermen's dependence on fossil fuels is still very high at 95.4% and has not decreased until now. The increased fuel price and reduced fossil fuel availability make fishermen struggle to fish. IMO (International Maritime Organization) noted that around 277 million tonnes of fuel are consumed by ships with fossil fuels. According to an emissions study conducted by IMO, 961 million tonnes of CO2 accounted for 2.5% of global emissions. This study aims to reduce exhaust emissions by vessels from fossil fuels by making the ship into a hybrid (Diesel-Pv). Making the ship a hybrid with solar panels will save fuel consumption. The method used is the trozzi method approach. The results obtained from changing the configuration to a hybrid can reduce the issued emission by around 57%.
