Abstract

The demand for small LNG carriers in Indonesia is increasing along with the increasing demand for LNG supply from the LNG field to the islands in eastern Indonesia. The distribution of LNG to islands in eastern Indonesia is not efficient if using a larger LNG carrier because in the islands there is no gas pipeline infrastructure to distribute LNG from the LNG terminal at the port to the user. With a small LNG carrier, the distribution LNG can use a small LNG tank that will be taken by land vehicles after the ship rests at the port. To design a small LNG ship, various calculations are needed so that the ship being built will have a good and efficient performance. One of them that must be calculated is the ship's resistance and engine power to be installed. In this paper the prediction of ship resistance and EHP BHP for prediction power of engine using numerical simulation methods. The results of this paper are for ship resistance at design 1 of 101.01 kN and for design 2 of 267.06 kN. In design 1 for EHP of 519.93 kW and BHP of 611.68 kW, and in design 2 EHP of 1373.87 kW and BHP of 1616.33 kW.

Abstract

The need for hot water on a ship is one of the facilities that must be obtained by the crew while carrying out their duties on the KM. Meratus Karimata is one of the ships that provide hot water as a facility for crew members. The heating system on this ship still uses the EHHW (Electric Heating Hot Water) heating system which will then be changed to the HPWH (Heat Pump Water Heater) system. This hot water need is based on the MLC (Marine Labor Convention) regarding the provision of recreational facilities on deck accommodation. The provision of hot water needs to be calculated and designed. The first thing to do is to calculate all distribution support components. Then the data for the needs of pumps with a power of 0.504 Kw, valves, shower taps, sink taps, pipe connections, and SCH 40 pipes with a diameter of ¾ "and 1" are obtained. After that, the design is carried out using software assistance. After the design is carried out, the calculation of component costs is carried out with details of the valve price of IDR 10,129,000, pipe IDR 5,186,000, pipe connection IDR 1,751,000, supply pump IDR 1,150,000, HPWH 95,300,000. The price of EHHW and HPWH is a difference of IDR 21,300,000, which is more expensive for HPWH. However, in the calculation of fuel consumption, HPWH is more efficient with HPWH fuel consumption data of 0.11 liters/hour at a cost of Rp.1,249 / hour, while fuel consumption for EHHW is 0.77 liters/hour at a cost of Rp.10,116/ hour.

Abstract

The process of testing the leak on the valve on the important stages of vessels is carried out and regulated by the BiroKlasifikasi Indonesian (BKI) as a Class which refers to the International Association of Classification Societies (IACS).Pipes and fittings shall be tested by hydrostatic pressure not less than 1.5 times the nominal pressure. In this study, the 4gate valves tested had a nominal pressure from the manufacturer of 10 bar, so they had to be tested up to a pressure of 15bar. The valves have been tested one by one with the Hydrostatic Pressure Test method, using the Test Pump. From the test results found a leak in one of the valves, namely in the disc. The ecommendation given by BKI is to repair it by covering the leak using the material recommended rom the gate valve manufacturer using epoxy type iron glue.

Abstract

Corrosion is a problem that often occurs in submarine pipelines. This is because the metal pipe material is installed in environments that have a high level of corrosivity. Although corrosion cannot be avoided or eliminated, it can be controlled by cathodic protection. One of them is the sacrificial anode method. The aim of this research is to design a corrosion rate control in an underwater pipe along 13.5km, with a diameter of 16 inches for a design life of 45 years. The anode used is a 400 mm long and 40 mm thick anode made of aluminum alloy. In designing this cathodic protection, the writer refers to DNVGL-F103 and ISO 15589-2. From the results of this study, we will get the total anode needed to protect the pipe and the installation distance between the anodes. Based on the total anode, it can be seen the estimated cost needed in making cathodic protection.

Abstract

A bonded warehouse is a place to store imported goods, which can be accompanied by one or more activities in the form of packaging / repacking, sorting, merging (kitting), packing, adjusting, cutting, for certain goods within a certain period to be reissued. In the Minister of Finance Regulation (PMK) No.155 / PMK.04 / 2019 concerning Bonded Warehouses, the Ministry of Finance emphasizes that this tightening of supervision is carried out in two forms, both in terms of taxation and the mechanism for importing goods. This bonded warehouse policy is expected to reduce national logistics costs by reducing dwelling time at ports and accelerating access to raw material warehouses to industry. The essence of this study is to analyze the extent of the influence obtained by users of bonded warehouse services in terms of logistics costs. Cost comparisons are obtained from surveys with companies that have already utilized bonded warehouse facilities.

Abstract

A river estuary is a meeting place between seawater and river water and is a part of the river downstream. At the bottom of the river estuary, sedimentation occurs, because there is a meeting of sand/mud particles carried by river currents that meet with sand in the area around the coast. In this regard, it is very important to examine the characteristics of the estuary and its sediment characteristics, especially to provide information to surrounding communities and provide data on sediment characteristics that settle to determine more efficient dredging methods or find solutions so that dredging is not carried out annually. This research was conducted at the Soil Mechanics Laboratory of the Faculty of Engineering, Tanjungpura University, and in taking sediment samples at the Kapuas River Estuary. The time for taking sediment samples at 9 points and taking bathymetry data at 21 points is June 14 2019 while for laboratory tests on June 14-22, 2019. The method used is purpose sampling to take samples in the field, quantitative methods for testing in the laboratory. For data analysis using the USDA system method and the Van Zuidam slope category. From the results of field data collection, it was shown that bathymetry in the Kapuas River Estuary ranged from 2.6 m to 8.7 m at MSL + 0.8 m with the base contour in the Kapuas River Estuary categorized as Flat. The type of base sediment in the Kapuas River Estuary is dominated by the category of clay soil. Sediments can originate from muddy beaches that experience abrasion by water flow. Therefore, the solution so that it is not dredged annually, it is necessary to build a Jetty or coastal retaining wall.

Abstract

Indonesia has a sea area of ​​96,079 km2 and a coastline of 99,093 km, making Indonesia has the potential to utilize the sea as a new and renewable energy source. However, the use of new and renewable energy has only reached 6.2% in 2015. One of the marine energies that can be utilized is ocean currents. Awerange Bay, located in South Sulawesi, is a point that has a source of marine energy and can be used as an environmentally friendly, sustainable renewable energy. The current velocity in the Awerange Bay area in low tide can reach 0.25 - 0.36 m / s. So it can be possible to use tidal energy using turbines. The Kobold turbines take advantage of currents from seawater in Awerange Bay. By using a bi-directional (two-way) turbine that moves the turbine clockwise or vice versa. Turbines that are installed horizontally on the seabed can convert the kinetic energy of the turbines into electrical energy during tides, making the turbines suitable for use as marine tidal power generation. As a sample based on the Ministry of Energy and Mineral Resources, current energy can produce 1.2 MW / turbine. The big advantage of bi-directional turbines is that the propeller blades do not need to be reversed when the flow direction changes. This makes for a robust design, less expensive to build, maintain, and a lower risk of breakage. Also two-way turbines on average produce twice the electrical energy that uni-directional turbines, which only function during tides or floods.

Abstract

This article discusses the worker's safety assessment of the loading and unloading process that causes cargo product defects at Paotere Harbour. Makassar, which is the capital of South Sulawesi province, is known as the city with the largest majority population and is a dense flow of inter-island freight traffic. One of the Harbours that transportation the economy in Makassar is the Harbour of Paotere which provides dock services for fishing boats, passenger ships and cargo ships. Phinisi motor sailing ships are equipped with lifting equipment, namely cranes that can lift goods to facilitate the loading and unloading process of goods from the ship to the edge of the pier. However, the loading and unloading process ignores the safety and health aspects of work on the deck of the ship and on the dock. In addition, the results of the products being trans Harboured must also be considered if someone experiences product defects due to loading and unloading activities at the Harbour of Paotere. J-hook, a tool used to lift and move the sack by stabbing it in any place, can cause the sack to tear and the grain inside will slowly spill out due to gaps in the sack. The method used in this research is the descriptive method, namely: providing an overview of certain phenomena or certain aspects of the location under study. Descriptive methods are not only limited to data collection but include direct observation and interviews with workers. The strategic solution needed is the replacement of the cargo lift knot rope on the crane with a mooring rope net that facilitates the lifting process from the ship's deck to the Paotere Harbor pier. Replacing the J-hook whose function is to shift and flip the sack with an enlarged Jar Lifter tool and an adjustment of the material that is comfortable to hold and is not dangerous if it falls and hits the limbs of workers who are carrying out loading and unloading activities Paotere Harbor.
