Lack Of Knowledge

<p>in Indonesia is a region bordering the sea region of Indonesia determined by the law which included sea bed, land under it and water above it with the limit of 200miles. This is measured from Indonesian line of the sea.This whole time a lot of people see the shoreline as the sea border. This perspective makes us alienated and lack of knowledge to take advantage of the sea. This understanding also conjures the idea sea toll, to confirm that Indonesia is maritime country. Sea toll means building sea transportation with ships or sea logistic system which will serve nonstop back and forth from Sabang to Merauke. One of the factors to support this is by building ports (deep sea port) order to give faraway to big ships. A course that spreading as far as 5,000 kilometers or an eighth circumference of the earth One of the purposes of sea toll is to move the economy as efficient and evenly as possible. With the hope that, there will be ships back and forth on Indonesian water, so logistics cost will be cheap. That is why; sea toll is one of President Joko Widodo’s priorities which are also meant to develop Indonesia as maritime country and develop Indonesia as national unity. In addition sea toll can also be affirmation, that Indonesia is in every regions even if it is through ships.</p><p><strong>Keywords : Exclusive Economic Zone (ZEE) , Sea Toll , The Shaft Maritime, A Seaport</strong></p>

Rural Appraisal

Smoked fish processing business in Wab Village still used traditional methods (fumigation open) and are household enterprises (micro-scale enterprises) can be seen from the aspect of production and management aspects. Two aspects of this raise the priority issues faced by partners namely: how the fish correct fumigation techniques? What forms fumigation appropriate tool? How to manage capital and production business properly? How do I do the recording business activities in the notebook business correctly? And how to sell or market products correctly? Through methods of participatory rural appraisal, fisheries extension method, and the method pretest-posttest control group design, the implementation of community service activities carried out as a priority the settlement solution problem by doing: 1) Initial extension of community service activities; 2) Extension of heat curing, heat curing tool making appropriate, and the use of heat curing; 3) Counseling on capital management and production; 4) Extension of book production business records; and 5) Counseling about pricing, promotion, and strategy for dealing with the business of competition. So the outcome reached was contained fish products and marine worms (increasingly) the smoke as much as 25 / week; there are two tools used fumigation partners; there were five notebooks submitted to partners and capable of recording the three notebooks (book purchases, sales, and profit/loss); and 50 fish and marine worms (increasingly) smoke marketed in Wab Village.

Submarine pipelines must be designed to resist wave and current induced hydrodynamic forces especially in and near the surf zone. They are buried as protection against forces in the surf zone, however this procedure is not always feasible particularly on a movable sea bed. For this reason the characteristics of the sediment transport on the construction site of beaches should be investigated. In this investigation, the application of the remote sensing method is introduced in order to determine and observe the coastal morphology, so that submarine pipelines may be protected against undesirable seabed movement.

Band Pass

The 2003 Tokachi-oki earthquake (MJ 8.0) occurred off the southeastern coast of Tokachi, Japan, and generated a large tsunami which arrived at Tokachi Harbor at 04:56 with a wave height of 4.3 m. Japan Marine Science and Technology Center (JAMSTEC) recovered records of water pressure and sea-bed acceleration at the bottom of the tsunami source region. These records are first introduced with some findings from Fourier analysis and band-pass filter analysis. Water pressure disturbance lasted for over 30 minutes and the duration was longer than those of accelerations. Predominant periods of the pressure looked like those excited by Rayleigh waves. Next, numerical simulation was conducted using the dynamic tsunami simulation technique able to represent generation and propagation of Rayleigh wave and tsunami, with a satisfactory result showing validity and usefulness of this technique.

The Common

Pacem in Maribus once again stressed that an ocean regime must encompass the oceans as a whole and be considered as a sub-system of the entire global system. Jurisdictional decisions, including those affecting the Exclusive Economic Zone (EEZ), must reflect that paramount concern. It is not a matter of geographical realignment or of partition; marine ecosystem do not correspond to political demarcations. Nor is mankind, for which the concept of the common heritage is prescribed, confined to coastal states or to the present generation.In its discussions and studies, Pacem in Maribus has consistently stressed the significance of rapid scientific and technological developments which have radically changed the nature of many conventional uses of the sea and call for management as the only alternative to conflict and possible disasters. In its commitment to an Ocean Space Authority rather than to an International Sea-bed Authority, Pacem in Maribus contends that activities on the sea-bed cannot be dissociated from activities in the water-column, at the surface, and at the atmospheric interface; that the sea-bed must become part of an integrated management system for ocean space; and that claims to national jurisdiction carry a surrogate responsibility in that management.Pacem in Maribus contends that any Law of the Sea which does not respect and embody these overriding considerations will prove to be ineffective if not inoperable.
