Study of Suspended Sediment Distribution Based on Wind Monsoon in Pemalang Coastal Waters, Jawa Tengah Using Aqua–MODIS Data

Pemalang coastal water is a territorial waters with high navigation activity, especially fisherman activity. Another factor which directly interact with the territorial waters is a place empties into several rivers, among others Comal, Comal Lama, Banger, Sragi Lama, Kangkung, Sragi Baru, Bedahan, Waluh, Elon, and Baros rivers. The existence of those rivers give suspended sediment loading and caused sedimentation process in the territorial waters which mentioned before. Using remote sensing data, the distribution of suspended sediment can be watched. In this case use Aqua–MODIS satellite data.

The aim of this research is to know about the distribution of suspended sediment based on wind monsoon in Pemalang coastal waters using Aqua–MODIS satellite data. The method of this research was descriptive method through Aqua–MODIS satellite image data processing include image data collecting, secondary data collecting, field data collecting, image data digital analysis, field data analysis and examination test.

Study on Phytoplankton Community Structure in Segara Anakan Waters, Cilacap, for the Period of September to December 2004

Plankton is minute organism living drifted away in a water column. Phytoplankton is floral-plankton which able to synthesize their food using sun energy through photosynthesis process. In most time the presences of phytoplanktons influence the productivity of the waters, but in some extreme condition they can be dangerous for their environment too. The aim of this study is to identify community structure of phytoplankton in Segara Anakan lagoon and its related environmental factors, and hopefully the findings will be useful as back up data for the monitoring programmed of the lagoon.

Water Masses Characterization in Makassar Strait during INSTANT (International Nusantara Stratification and Transport) Cruise in July 2005

Water masses is body of water which is homogenous and is featured by it’s characteristics. The major characteristics to describe water masses are temperature, salinity and density as the main component to identify water masses which flows into an area, including Makassar Strait as the main route of Indonesia Trough Flow (ITF).

The purpose of this research were to show the distribution of temperature, salinity and dissolved oxygen in Makassar Strait in July 2005 and to study water masses characteristics which flowed along Makassar Strait. The coverage area in this research were between 4° 59′ 24.0″LS – 3° 29′ 24.0″ LS and between 118° 6′ 0.0″ BT – 118° 48′ 0.0″ BT. The research was carried out during INSTANT (International Nusantara Stratification and Transport) cruise on July 3rd – 14th, 2005. The methods used in this research were measuring physical oceanography parameter such as temperature, salinity and density by using CTD (Conductivity Temperature Depth) and measuring dissolved oxygen by titration method. Then the data was analyzed by several graphic profiles, vertically, horizontally, and T-S diagram to observe the origin of water masses in that area.

Bioaccumulation Level of Heavy Metal Pb (Lead) in Soft Tissue of Mangrove Cockle (Polymesoda erosa)

Mangrove cockle (P. erosa) is one of the Segara Anakan resourches. This cockle live in ecosystem of mangrove forest with salinity fluctuation and high level acidity. This cockle can be found in Mimika, Papua and Segara Anakan, Cilacap. The used of Mangrove cockle is as an alternative food substance which have high economic value was threatened by heavy metal polluted in their ecosystem that finnally dangerous for human being.

Eksploration of Bacteria Associated with the Soft Coral Lobophyton sp. as Probiotic Candidate to Control Vibriosis

Disease is now considered to be the limiting factor in aquaculture. Often it caused great financial loss. Disease can cause mortality, cretinism, longly maintain period, highly feed convertion, lower density and decrease of productivity. Disease can be caused by pathogen organism such as protozoa, bacteria, fungi and virus.

Vibriosis is one of bacterial disease caused by vibrionaceae family, the effect of the attack is massive. So far, disinfectants and antimicrobial drugs are used to treat this disease. The continous use of antibiotic to treat this disease is causing resistancy at pathogen bacteria. They can transfer their resistance genes to other bacteria that have never been exposed to the antibiotic. Probiotic is a necessary developed alternative to treat vibriosis. The result of this tecnology is a safe product to consumer because it does not contain chemical residue that is dangerous to our health.
