Flood Canal was built to reduce the impact of flood during the rainy season that is river catching / times that passes in The Special Areas of The Capital of Jakarta and can accommodate the flood from Depok and Bogor. The city government is also building a mass transportation mode in Jakarta that integrates railway lines, light rail transit, roads, busway and subway networks targeted for completion in 2017 and will be integrated with the outer ring train, but if the floods are partially paralyzed. For this reason, it is necessary to empower the Flood Canal function as an alternative transportation infrastructure that is environmentally friendly water bus with a capacity of 30 passengers that can operate even in flood condition. A number of preliminary studies of water buses of earlier models and concepts have been conducted to obtain a suitable and feasible prototype to operate in the flow of West and East Canal Floods. To obtain a good water bus size calculation based on comparison ratio, general arrangement design, hull form design with CAD, hydrostatic calculation, engine power estimate and determination of required energy, stability calculation. The goal is as an environmentally friendly alternative transportation mode, with the advantage of being able to operate even in flood situations. It is expected to change the customs of the community for the canal to be the front of the house instead of the back of the house.

KARAKTERISTIK HIDRODINAMIK DESAIN LAMBUNG KAPAL DENGAN RISE OF FLOOR DAN TANPA RISE OF FLOOR PADA PERAIRAN DALAM DAN DANGKAL Bambang Sudjasta; Wiwin Sulistyawati

In principle Manoeuvrability vessel is strongly influenced by the design of the hull, propulsion system and steering system. Some of these elements are directly give a significant effect on the hydrodynamic force and moment when the ship maneuver. Analysis of hydrodynamic aspects is a stage that is absolutely necessary in the design process of a ship, especially for ships operating in waters with varying depths. By the time the ship through the shallow waters can increase frictional resistance surge barriers and the vessel which resulted in a decrease in speed boats. The hull form with rise of floor and without the rise of floor by focusing on the analysis of the obstacles, the character of the ship motion and acceleration criteria in deep and shallow water conditions. In numerical calculations for shallow water conditions (shallow water) with a ratio of water depth and draft of the ships, h / d = 1.2 and deep water (deep water) with h / d = 20. Evaluation of the obstacles, the character motion and acceleration for heave, roll, pitch and yaw is done by combining numerical methods through Hullspeed and AQWA Ansys program. From this numerical calculation, it can be analyzed with the rise of the hull form floor and without a rise of floor optimum for deepwater and shallow.

ANALISIS KEBUTUHAN PEMASANGAN ZINK ANODE UNTUK MENCEGAH KOROSI PADA LAMBUNG KAPAL KAPAL GENERAL CARGO Bambang Sudjasta; Purwo Joko Suranto; Hernia Setiani

Needs installation of cathodic protection to prevent corrosion of the ship in the sea water medium is a must so that the ships can be used as long as possible, but the effectiveness is very limited lifespan sacrificial anode that time should be right on time. For the replacement timing becomes important to do, hull plate is first exposed areas of sea water. In this area of the hull bottom water or top area of water exposed to corrosion range. Corrosion of hull plates can lead to decline in strength and service life of ships, reducing the ship's speed and reduce safety and security of cargo and passengers. From the calculation of the aluminum anode needs indicated that there is a difference between the life of the anode replacement is supposed to 5.25 years. The number of victims aluminum anode required to ship the object of the research is based on the calculation is 12 pieces (± 44.2 kg), lower than the number of anode installed in the field about 24 pieces (108 Kg). So the amount of victims aluminum anode mounted on General Cargo Ship in the field is redundant with past-year use of 5.25 while the turn is done for 3 years. For the owners of the ship, you should use zinc or magnesium anode victim since both of these materials have an efficiency of 95 % compared to aluminum, is only 50 %.

This research was conducted to know the change of Gross Tonnage (GT) size of fishing vessels before and after re-measurements by measuring experts appointed according to the Ministerial Regulation of the Ministry of Transportation Year 2013 on Ship Measurement, as well as calculating the expected revision of Non-Tax State Revenue (PNBP). Data processing using SPSS program, one of which is paired sample T-test is a test that can compare data before and after data. Tests paired sample T-test has a requirement, that the data must be normally distributed, then the kolmogorov smirnov normality test to determine the normal distribution data or not. The result of kolmogorov sminov test concluded normal distributed data and can be tested paired sample T-test. From result of paired sample T-test is known comparison of data have real difference. Then the analysis of this research was done and resulted some conclusion that difference of GT increase equal to 73% before before measurement, PNBP assumed can accept new income equal to Rp. 3,458,304,- for port services, and navigation services Rp. 11.376.000,- if calculated one week ship only operate one time and for one year.
