Karimata strait and the java sea is one of the most densely shipping lanes in the maritime country of Indonesia. Information of a significant wave is needed to safety navigation. The prediction of a significant wave mostly employs the modeling using wind as input data to produce an early warning warning prediction. Characteristic of a significant wave shows the maximum wave height in the strait and the java sea karimata occurs in west monsoon (January) and east season (August) every year. Especially at the peak of west monsoon (January) maximum wave height reach 1.5-3 meters in Karimata Strait, and reach 0.5-2.5 meters in Java Sea. The frequency of significant wave occurences mostly extend until February, where wave height in Java Sea will stay the same (0.5-2.5 meters), while in Karimata Strait is little bit decrease (1-2.5 meters). Recommended to all sea transportation users, in those regions during January and February, to avoid using ship with the hull is less than 3 meters height.Keywords: significant wave characteristic, Karimata Strait, Jawa Sea, Wind, Modeling

Seaweed (Eucheuma cottonii) is one type of fishery commodities with high economic value. These commodities have been developed in several areas in Indonesia, one of them is in the Banggai Islands, Central Sulawesi. Problems in the development of commodity seaweed in Banggai is a lack of understanding and seriousness in seaweed cultivation, lack of variety in designing seaweed cultivation techniques as well as the suitability of the location of aquaculture that can support increased productivity. The use of long-line method is considered still the best way. This study aimed to evaluate the seaweed cultivation methods long line in the village of Liang and Apal, Banggai Islands, Central Sulawesi. The results showed that the seaweed growth rate were not significantly different when we compared them based on sediment types. For instance, Liang village sediment was sandy silt while we found rocky substrate at Apal village. Therefore it can be concluded that long line method can be applied without taking into account the type of sediment. Keywords: sea weed, long-line methods, Banggai archipelago

Mineral mining (i.e. gold) activities in the land and coastal boundaries of West Sumbawa district are expected to increase the content of heavy metals in the marine and coastal waters surrounding. A residual of mining processing produce heavy metals disposal. In this study, the distributions of heavy metals (i.e. Hg, Cr6+, Cu, As, Ni, Zn, Pb, and Cd) were measured in the water column and bed sediments of coastal waters of West Sumbawa. This study was conducted during dry season in July 2011. The results showed the heavy metal concentrations in water column were below the threshold level stipulated by the Minister Decree No. 51/2004, except for Cu. The heavy metal contents in bed sediment were low and varied among sampling points excepting for Cu content which was remarkably high (101,7 mg/Kg).
