Abstract The United Nations Convention on the Law of the Sea (UNCLOS 1982) affirms that the government has sovereign rights, jurisdiction, and obligations in Indonesia’s EEZ. Indonesia has an interest in protecting sovereign rights and increasing state revenues in the waters of the Exclusive Economic Zone (EEZ). That sovereign right is to use fishery resources responsibly for the benefit of the nation and society as a whole. The sole purpose of this qualitative research is to optimize fisheries utilization in the Rote Ndao Regency whose waters include the Fisheries Management Area of 573 (FMA-573) in the EEZ. The analysis had been carried out with a case study approach and then descriptively elaborated. The results showed that: 1) the use of fisheries in FMA-573 was carried out by traditional fishermen (using vessels ≤10 Gross Tonnage/GT) and fishermen using vessels >29 GT; 2) supervision is still needed for the improvement of ships and human resources; 3) there are still violations of territorial waters by traditional Indonesian fishermen. The policy recommendations that must be carried out by the government are: 1) encouraging local fishermen to catch fish in the FMA-573 area by providing stimulus for ships and fishing gear; 2) allocate budget to purchase a new fleet of ships and add supervisors; 3) increase the number of fishery instructors to foster and socialize the boundaries of Indonesia’s EEZ with Australia.

Abstract. Low-frequency sea level variability can be a critical factor for several wave energy converter (WEC) systems, for instance linear systems with at a limited stroke length. Consequently, when investigating suitable areas for deployment of those WEC systems, sea level variability should be taken into account. In order to facilitate wave energy developers in finding the most suitable areas for wave energy park installations, this paper describes a study that gives them an additional tool by exploring the annual and monthly variability of the sea level in the Baltic Sea and adjacent seawaters, with focus on the Swedish Exclusive Economic Zone. Over 10 years of reanalysis data from the Copernicus project have been used to conduct this investigation. The results are presented by means of maps showing the maximum range and the standard deviation of the sea level with a horizontal spatial resolution of about 1 km. A case study illustrates how the results can be used by the WEC developers to limit the energy absorption loss of their devices due to sea level variation. Depending on the WEC technology one wants to examine, the results lead to different conclusions. For the Uppsala point absorber L12 and the sea state considered in the case study, the most suitable sites where to deploy WEC parks are found in the Gotland Basins and in the Bothnian Sea, where the energy loss due to mean level variations is negligible.

The Impact

The Indian mackerel (Rastrelliger kanagurta) is one of the most commercially crucial epipelagic scombrid where it is caught in the Exclusive Economic Zone (EEZ) off the South China Sea (SCS). High demand for fisheries resources is a challenge for fishers to achieve optimal fish landing targets. By using R. kanagurta catch data, and high resolution satellite data of chl-a and SST (MODIS-Aqua) and SSH (AVISO) from 2018 together with boosted regression tree (BRT) model, this study aims to determine the impact of sea surface temperature (SST) increase on the potential catch of R. kanagurta based on temperature projection of IPCC-AR5-RCPs scenarios. BRT modelling result indicated that during the northeast monsoon (NEM), at elevated temperature of 1.80 and 2.60 ℃ showed that the potential fishing grounds of R. kanagurta increase in the area especially in the northern part of the EEZ. However, at elevated temperature of 3.30 ℃, the potential fishing areas was found to decrease along the coast of Peninsular Malaysia. Meanwhile, during southwest monsoon (SWM) and inter-monsoon transition, at temperature rise of 1.80, 2.60 and 3.30 °C showed a significant reduction in the potential fishing area of the R. kanagurta potential fishing grounds especially along the coast of the EEZ off SCS. Results indicated that changes in SST influenced suitability of habitat which affected the distribution of R. kanagurta. Understanding the impacts of temperature increase would contribute towards future sustainable fisheries resource management strategies.

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>
