Abstract

The reliable of the engine room design can affect the success of the ship both in terms of the propulsion nor the self-righting. The design of engine room is one aspect of being able to apply self-righting capabilities. There is an innovation for the development of closed fast boats with self-righting capabilities which have not yet been found in Indonesia. Self-righting is the ability of the ship to be able to return to its original position after experiencing a rolling of 180 °. The design of engine room using the inherent self-righting method is one method to be able to apply self-righting capabilities. The focus of this research is to study the effect of the gravity point on the engine room longitudinally, vertically and transverse on the ability of self-righting. In the engine room obtained LCG 4,044 m, TCG 0.006 m and VCG 0.830 m. The self-righting simulation is divided based on 5 load case conditions. The condition of load case 1 the value is max GZ 0.732 at 51.8 °. The condition of load case 2 the value is max GZ 0.672 at 70 °. The condition of load case 3 the value is max GZ 0.577 at 61.8 °. The condition of load case 4 the value is max GZ 0.687 at 69.1 °. The condition of load case 5 the value is max GZ 0.596 at 59.1 °. At the 5 load case conditions has comply the HSC 2000 code stability criteria and can apply self-righting ability because it comply the requirements of having a positive GZ value of 180 °.

Abstract

This research modified the insulation of coolbox material by utilizing a mixture of teak wood sawdust (Tectona grandis L.f.) and previously immersed bagasse fiber (Saccharum officinarum) into an alkali NaOH solution to improve the mechanical properties of the fiber and reduce the value of material thermal conductivity. The most optimal test and analysis results were obtained by composing 50% teak wood sawdust with 50% of previously immersed bagasse fiber in an alkali NaOH solution at a level of 15%. The obtained conductivity value is 0.2907 W / mK, the density is 0.4901 gram / cm3. Experiments on changes in temperature of ice, fish, and coolbox chamber as well as experiments on the duration of fish preservation in the coolbox with variations in the composition of straight fibers have better performance compared to the variation of random fiber which is able to preserve fish for 34 hours with minimum temperature of 0, 2 ° C. For fishing duration of two days, coolbox with a variety of straight fiber has almost the same performance as coolbox made from styrofoam and has the potential to replace styrofoam because it is more environmentally friendly.

Abstract

Dimple is a concave commonly seen on a golf ball. These concaves turn out to have an effect on the movement of the golf ball so as to help the golf ball fly further. From the advantages of golf balls, whether the cavity can help to reduce the friction of the hull with the water surface. This study aims to determine the effect of dimple on flat plate with different types of flow (laminar, transition, and turbulent) and how it affects the coefficient of friction (Cf). In addition, with the difference in the ratio of the concavity (Rc) how it affects the coefficient of friction (Cf). From these influences later we can know how the optimal dimple design on the hull of the ship. The simulation method will be done with Numeca Fine Open. This software can simulate the complicated shape dimple well than any other software. The result of the analysis will be known to decrease the coefficient of friction (Cf) during laminar flow, transition, and turbulent. With a growing influence when turbulent flow. In addition, the greater the ratio of the concentration will decrease the coefficient of friction greater than the small-scale ratio.

Abstract

Ship with a dynamic positioning system has the ability to maintain her position dynamically. To be able to maintain the position, generally, ship with a dynamic positioning system have several thrusters located at bow or stern of the ship. Based on the propulsion system, there are 2 types of thruster which are mechanical thruster and electrical thruster. In electrical type, the thruster is driven by an electric motor supplied from the generator. In addition, on dynamic positioning vessel equipped with the electrical thruster, there are also VFD or Variable Frequency Drive to control the speed of motor thruster. The use of VFD components in the system may cause harmonic interference. Harmonic itself can be regarded as distortion in the sinusoidal waves due to the interference of other waves that have integer frequency multiples of their fundamental frequency due to the operation of non-linear thruster motor. Some of the most affected components of this distortion are the communications equipment and the components used for measurement. This research conducted an analysis of harmonic disturbance arising from the operation of 2 units bow thruster on DP Ship by simulating 6 scenarios of generator configuration using simulation software. The results from this research were total harmonic distortion value or  VTHD of the system that complies with standards and rules, also the specification of a passive harmonic filter to reduce the VTHD value at the specific harmonic order.

Abstract

Natuna Sea is one of the places in Indonesia, which has a high potency of fish up to one million ton per year. Fisherman in Indonesia relies too much on the fossil fuel, which has limited resources. The author wants to redesign the fishing vessel into the battery electric fishing vessel that can be recharge to reduce the use of fossil fuel and also to increasing the revenue of the fisherman. To minimize the capacity of the battery, the fishing activities concept is also change into centralized fishing activities which the activities is centralized in an open sea and has the offshore building as the fishing base that has power station to recharge the batteries and cold storage to collect all the fishes. As the object to redesign, it is used 10 GT purse seine fishing vessel. As the results of the calculation, it gets the total battery capacity 6000 Ah for operation 11 hours (4 hours travel time, 6.5 hours fishing activities, and 0.5 hours break). Based on the technical and economic analysis, it can be concluded that the battery electric fishing vessel has a better revenue and fewer expenses than the diesel-powered fishing vessel.

Abstract

Based on the 2015 annual energy forecast from Indonesia’s Agency for the Assessment and Application of Technology (BPPT), if present trends in energy usage continue unaltered, transport fuel consumption in Indonesia will increase on average almost 5% per year through 2050. Currently, liquid fossil fuel accounts for around 35% of Indonesia’s energy demand across all sectors. From various renewable energy and possible alternative fuels to replace the consumption of fossil fuels, biodiesel is projected to have potential to be developed regarding to the simple production process and affordable feed stocks. Biodiesel, as diesel engine fuel alternative, receives more attention among many feasible options. Biodiesel as one of the renewable energies, biodegradable and nontoxic fuel is expected to be one of the solutions. With the affordable feed stocks that can be obtained from various organic source like vegetable oils or animal fats and also the simple production, From the discussion of this Bachelor Thesis, the economic feasibility, necessary equipment and the time of storage of the biodiesel will be analyzed for biodiesel production plant including investment cost of making the biodiesel production plant by calculating the capital cost and the operational cost of a 5000-ton annual capacity of biodiesel. The purpose of this study is to analyze the investment of the biodiesel production facility by using a feasibility study method by using four parameters of economic feasibility study namely Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and the Profitability Index (PI) for assessing the Investment. Th result obtained is that the biodiesel production facility with the annual production of 5000 ton of biodiesel is feasible
