Abstract

The auxiliary engine in its operation requires complete combustion to get an effective engine, one of which is to use the injector mechanism. Incomplete combustion can cause the engine to not work optimally, it will even cause damage to theengine so that it requires the cost of repair and replacement of its spare parts. The injector has a way of working by providing high-pressure fuel from the injection pump. The main function of a diesel injector is a device to shrink fuel until it breaks into smooth parts (mist) in high temperatures. The high temperature will have an impact on the engine so that regular maintenance is needed on the engine injector. This research uses data collection methods conducted by library research and document studies. This research includes: finding data of the main engine (injector), analyzing and identifying damage to the injector, repairing, and testing the injector engine.

Abstract

The portal structure generally consists of 2 and 3 dimensions, the loads that work on it are also varied adapted to the purpose of the portal itself is used. A portal structure of either 2 or 3 dimensions is a tructure composed of beams and columns, so it is generally reinforced with a diagonal stem called a brace. The study aims to analyse the influence ofbrace configurations on 2-dimensional portals. The structure is modeled after a varied configuration of brace consisting of 5 models. The condition of the fifth boundary of the model is the joints and clamp with a constant axial load point working on the vertical pole. The portal dimensions, yield voltage, modulus of elasticity and poison ratio are assumed to be constant. For modeling, computation and analysis, used computer auxiliary programs namely SAP 2000. The results gained are focus reactions, point displacement and deformation of the five models.

Abstract

PT. Sinergi Perkebunan Nusantara plans to use the Lampia port for shipping of Crude Palm Oil (CPO). Lampia Jetty has more than ten years old so that its carrying capacity against external loads may have decreased. Therefore for the operational safety of the ship, it is necessary to study the engineering capacity of the pier. By knowing the engineeringcapacity of the existing pier, the maximum ship dimensions that can be served by pier can be determined. This study began with the collection of supporting data consisting of ship data, hydro-oceanographic data, bathymetry data, pier structure data and earthquake data. Furthermore, the load calculation that works on the pier consists of dead and live loads, earthquake loads, ship impact loads, current loads, wave loads, ship tensile loads and wind loads. After the load calculation is completed, then the pier modeling is done using SAP2000 software followed by inputting the load using aspecific combination of loading and running model. In this study the dimensions of the ship were varied namely 500 ton, 700 ton, 1000 ton, 2000 ton and 3000 ton. The indicator used in assessing the technical capacity of the pier is the safety factor (SF) as a function of the ship DWT. Based on the results of the strength analysis of the pier structure, it wasfound that the existing pier is capable and safe serving ships with a size of 27 1027 DWT if it uses a safety factor (SF) 1.5. Whereas if use the safety factor (SF) 2.0, the existing pier structure is capable and safe to service ships with a size of ≤ 510 DWT.

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

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

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.
