Abstract

Cavitation is a detrimental phenomenon to ship operations because it causes many losses. It caused some effects i.e decreased propeller efficiency, damaged propeller material, lower ship speed, vibration, and extreme noises. In that regard, this research conducts cavitation analysis on controllable pitch propeller (CPP) by varying number of blade i.e. 3, 4 and 5 blades; diameter i.e. 30, 40 cm and 50 cm; also pitch i.e 0.4, 0.6 and 0.8.  The research method is carried out by the author in this study by conducting a simulation method based on the CFD approach. The simulation process consists of 3 stage-post processor, solver manager, and post-processor. From the simulation based on the CFD approach result, it was found that propeller rotation has an effect on the pressure ratio value. As the propeller rotation increase, the value of the pressure ratio will increase as well. The value of the pressure ratio in propeller design affects the cavitation area that occurs in the propeller. The percentage of the cavitation area on the propeller has an increasing tendency with the number of blades, rotation, and pitch. On the propeller with diameter 300 mm, 3 blades, pitch 0.8 at rotation 125 rpm no indication of cavitation, then it increases to 1.41% at rotation 175 rpm and keeps getting higher at rotation 225 to be 4.22% from total propeller expanding area. Whereas at rotation 225 rpm and pitch 0.4 is 3.38 %, then it becomes 3.85 % at pitch 0.6, which is getting bigger at pitch 0.8 that is 4.22 %.

Abstract

Batam City, which is part of the Riau Islands province, is a connecting city between Indonesia and Singapore. Batam City is located in a very strategic location in the border region between countries, neighboring one of the world's business centers, namely Singapore. For this reason, marine transportation has a very important role in maritime countries like Indonesia. The high intensity of Batam and Singapore transportation cannot be separated from the Chinese population of Batam which is a community group in the city of Batam. The existence of Batam Chinese has been going on for centuries, since they came from mainland China using boats. With tenacity, social networks and geographical proximity to Singapore, Batam Chinese people become dominant in the economy in Batam. This study seeks to show maritime aspects and shipbuilding technology and their relationship with social society through transnational concepts. With globalization, and to develop networks, people really need sea transportation to support the transnational process. For all that, maritime safety is needed which greatly affects the sustainability development efforts, especially sea transportation activities.

Abstract

Many factors are deemed influencing team or group performance. This research identifies influence of variables of leadership, followership and loyalty on team performance.  This research is quantitative research on path analysis by using SPSS program. The result is loyalty and followers don’t have direct positive effect on team performance, but through leadership variable as intervening variable. Leadership variable has direct positive effect on team performance and loyalty, and followership variable has direct positive effect on leadership variable.

Abstract

Indonesia as an archipelagic country consists of thousands of islands and has a large sea area so that the required mode of transportation is sea transportation as a means of mobility and driving national economic development. In addition, Indonesian waters serve as a liaison between cities, as well as between countries. As a border on the island of Sulawesi, the city of Bitung is a link between Indonesia and the city of Davao City in the Philippines. For all of this, security for shipping, especially at the border, is needed to support the smooth delivery of goods by using Ferry Ro/Ro ships so that sea transportation activities in general and trade and economic activities between the two countries can run smoothly because maritime safety greatly affects the continuation of development efforts

Abstract

The development of the shipping and shipyard industries in Indonesia over the past ten years has been very slow. Some of the causes, including low productivity and capacity, are the main reasons for this industry's penetration. In addition, the weakening of the national economy as a result of the weakening of the global economy also affected the domestic shipping industry. The competitiveness of the shipping and shipyard industry is influenced by industrial competitiveness and national competitiveness, so that shipyard industry problems must be solved comprehensively, accompanied by strategic and systematic steps in order to be able to compete sustainably. This study aims to analyze the strategies used by several shipping companies and shipyard companies to be able to survive and compete to win and get through severe conditions. This study uses descriptive qualitative method, which is supported by semi-structured interview techniques to obtain the data used in determining the resource person, using a purposive sampling method. The data collected is then tested for validity by using the triangulation of data sources to process the data obtained in developing alternative strategies using SWOT analysis (Strength, Weakness, Opportunities, Threat) In addition to the combination of SWOT methods. The findings of the research results state that all companies carry out defensive strategies so that they are a company that still exists today.

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.
