Abstract

many industrial diesel engines are used as the main engine of the ship. Apart from being relatively cheaper, the availability of industrial engine is also very abundant, and the repair process is also not too complicated. However, when viewed from the SOLAS regulations related to the main requirements for a ship propulsion engine, it must also be considered, because it operates at sea, so that ship engines must be tougher than industrial engines, especially related to engine performance when experiencing rolling and trim. The purpose of this research is to test the feasibility of industrial diesel engines being operated on ships. By using a water-cooled single-cylinder diesel engine which is commonly used in small ships. The experimental method was used in this research to obtain optimal results according to the conditions in the field, the engine was made in three variations, namely the normal condition (without inclination angle), the rolling condition of 150, and the trim condition of 50 which complies with SOLAS regulations related to the inclination angle. The results of the research obtained torque, Specific Fuel Consumption (SFC), and engine thermal efficiency in various engine variations. The highest torque is in the condition of the 150 rolling engine, which is 13.87 N.m. The lowest SFC is in the condition of the 150 rolling engine, which is 194 gr/kW.h. and the highest thermal efficiency was also obtained at the condition of the 150 rolling engine, namely 44.9%. The higher the engine speed, the higher the engine performance value in rolling 150 conditions, and the 50 trim conditions experience an increasing trend, but in low rotation conditions (750 Rpm) the performance decreases. Seeing the results obtained, a water-cooled single-cylinder diesel engine can be used as a small boat propulsion engine.

Abstract

The Internet of Things (IoT) and Big Data (BD) are growing significantly. IoT is defined as a gateway of technology to digital transformation. To work effectively, BD, Artificial intelligence (AI), and blockchain all rely on those data. Once the physical framework information is changed into computerized digital data, an opportunity opens up to improve vessel operations. Research shows that much of the hidden information can help improve vessel operations by leveraging BD and IoT. Therefore, other sectors of the value chain players such as consignees, shipyards, shippers, manufacturers, and classification societies are also interested in maritime BD. In recent years, the world's ship logistics industry has undergone major changes due to the global shipping cargo movement. The availability of numerous BD is also growing exponentially. This will make it possible to utilize many BDs and IoT in the shipping industry. Successful utilization of these BDs and IoT will bring about major innovations in the shipping industry. In this study, we reviewed several applications of BD and IoT in the maritime domain and developed a ship allocation model using maritime BD and IoT-extracted data. As a result, ship allocation establishment is discussed, and the ship allocation result is evaluated.

Abstract

Anchor is a device for tethering a ship to the bottom of the water, in the sea, river, or lake, so that it does not move from place to place due to gusts of wind, current, or waves. Anchors are heavy equipment that is dropped to the seabed from a ship or boat to maintain its position so that it does not drift. PT X has several tug boats, small vessels whose function is to pull or push large ships in port. In addition, this ship also functions to pull barges filled with coal from the coal processing plant to be brought to the port, where the coal is unloaded to be carried by transport trucks. On these barges, damage to the anchor machine often occurs, especially the teeth on the gear-box, axle pulleys (pulleys), the main shaft of the main-gear (main gear), the gear-box casing, the teeth on the main-gear and others which have been sufficient so far. Interfere with operations, and the ship becomes idle. For this reason, this research was conducted to study the change in the anchor system from the glide model to a new system in the hanging model, in order to reduce the use of anchor winch power and avoid damage to the gear-box and anchor engine.

Abstract

Ship repair project planning still often encountered problems that delay ship repair projects to achieve complete ship repair projects. Delays are due to frequent mismatches between ship repair scheduling and conditions that occur at the shipyard. The most commonly used method is the Critical Path Method (CPM). But in reality, the CPM method is considered less effective because there is still safety time for each job. Technological developments found the latest method, namely Critical Chain Project Management (CCPM). This method removes the safety time contained in the CPM method and replaces it with buffer time which is placed at the end of work activities. This study aims to analyze the duration of the critical path, determine labor costs, and the amount of buffer duration on the repair of the Geomarin-III 649 DWT ship. Based on the calculation results obtained on the repair of the Geomarin-III 649 DWT ship with the Critical Chain Project Management (CCPM) method is 10 days, 10 days faster than the normal duration. The labor cost obtained using the CCPM method is IDR. 54,017,500, saving 35% of the normal cost is IDR. 82,680,000, but if the buffer time is used thoroughly, the total estimated labor cost for the CCPM method will increase due to the addition of labor and the duration of the buffer time obtained by the CCPM method as a substitute for safety time, which is 9 days project buffer and 3 days feeding buffers. Based on this research, it was found that the CCPM method is considered effective and can accelerate the duration of the project and minimize labor costs.

Abstract

This research aims to determine container services, to determine projections and the need for container facilities in relation to traffic projections. This study used qualitative descriptive analysis, namely a method that explains in the form of numbers from the growth of activities. This research was conducted with interviews, library research and documentation. The results of the study show that the flow of container ships has increased. In 2020 it was projected to be 355 calls. It will continue to increase until it is projected to be 560 calls in 2029. Meanwhile, the projected realization of the flow of goods in containers in 2020 was 1,243.164 tons, and the realization of containers is predicted to be 2,015,767 tons. The Berth Occupancy Ratio can be maintained at a maximum of 70% according to the standards, so the length of the wharf at Ambon Port where in 2021, the flow of containers has reached 128,662 TEUs with the number of container ships 377 Calls, the length of the container reached 352 meters. As for the storage yard, the required storage area is 42,316 m2. As for the storage yard at Ambon Port, until 2029, the required storage area is 42,316 m2.
