<![CDATA[Rapid growth of technology in sea transport requires much number of seafarers. Indonesian National Ship owners Association (INSA) claims that the need of seafarers is getting increased hand in hand with Cabotage policy which obliges whether all domestic or national sea transports should use nation-flag vessel and conducted by national sea transport shipping company as well as occupied by Indonesian crews. Shipping agent is needed by foreign shipping company to serve all the vessel needs, crew and ship cargo. Shipping agent also arranges all documents as well as all the crew needs. It deals with the crew when the crew is getting sick, extending expired documents, also arranging letter for special ease of immigration for foreign vessel crew. All crews and foreign expert who work in Indonesia territory should get supervision and control from immigration affair especially those who work using sea transport. The purpose of arranging letter of special ease of immigration is to avoid crimes which are many caused by uncontrolled incoming and outgoing flow of foreign crews. For example it avoids smuggling, illegal immigrant, terrorism, drug abuse which commonly happens in Indonesian immigration territory. Directorate general of immigration even tends to maximize immigration officers in handling the incoming and outgoing flow of foreign workers or foreign crews especially those in foreign vessel. This research belongs to qualitative research with descriptive approach]]>

<![CDATA[This research is aimed at getting to know the influence of as much as 99% level of alkali treatment (NaOH) or 60 gram of each in one liter aqua and soaked during three hours, heated with the temperature of 140o Celsius during 10 hours. This research is also intended to know the combination of 99% level of Alkali treatment (NaOH) or 60 gram of each in one liter aqua and soaked during three hours continued with the heating with temperature around 140o Celsius during ten hours toward the content of crystalline index (Cl) which correlates with Kenaf fiber strength as composit material of nature fiber. The result of the research shows that the highest content of crystalline index is possessed on Alkali treatment which is combined with the heating as much as 79,908% followed by Alkali treatment as much as 68,389% extended by heating treatment as much as 62,707%. The research also shows that the lowest content of crystalline index is the untreated fiber as much as 62,045%.]]>

<![CDATA[Oceans cover 71 percent of the earth’s surface. They constitute a natural solar energy collection and storage system, and the resulting thermal energy can be drown off 24 hours a day by OTEC Plant. OTEC (ocean thermal energy conversion) power plant is one candidate to produce electric energy. OTEC transforms the heat stored in surface water of tropical oceans into mechanical work to produce useful energy. The aim of this paper was to investigate the equation of boiler in OTEC technology. The surface temperature of the sea water which is located Kalianget donan and Cilacap region between 32 up to 35 with a depth of 30 to 100 meters produce the greatest efficiency is 0.19.]]>
