<![CDATA[The purpose of this study was to determine shoreline change along the coast of Ladong, Mesjid Raya subdistrict, Aceh Besar district, Aceh province in the 5 years period started from the year 2011, 2012, 2013, 2014 and 2015. Ground check was implemented in August 2016. This study utilized Geographic Information System technology (GIS), remote sensing and by utilizing Google Earth to capture aerial photo. The result from this research showed that each year the shoreline changes, either it was abrasion or accretion. In 2011-2012 the value of abrasion reached 1.1 ha and the value of accretion reached 0.5 ha. In 2012-2013 the value of abrasion reached 0.3 ha and the value of accretion reached 0.8 ha. In 2013-2014 the value of abrasion reached 1.2 ha and the value of accretion reached 0.2 ha. In 2014-2015 the value of abrasion reached 0.2 ha and the value of accretion reached 1.5 ha. The value of the annual abrasion average reached 0.56 ha and the value of the accretion was 0.58 ha. The largest abrasion happened in 2013-2014 which reached 1.2 ha. The total value of 5 year abrasion was 2.8 ha and the total value of accretion was recorded 2.9 ha. The process of abrasion and accretion also caused a change of the length of Ladong’s coastline every year, and the river estuary was one of the reasons that caused abrasion or accretion]]>

<![CDATA[Lemuru fish is one of fishery commodity that has high economical value and one of fish that most catched by fisherman in Bali Strait. Lemuru fish had been caught in Bali Strait was fluctuating every month and every years. This condition was related with food source of Lemuru fish such as phytoplankton and zooplankton. So this research was conducted to explained the relationship phytoplankton and zooplankton abundance with Lemuru fish catched in Bali strait. This study focus in Bali strait during March until May 2017. Determination of sampling point used area sampling method while water sampling occured in surface water with pouring method. Total of phytoplankton and zooplankton abundance in Bali strait in March until May had formed the sinusoidal model with their abundance ranged 301 ind/L – 604 ind/L and 7 ind/L – 12 ind/L. Plankton abundance in Bali strait in March until May (transisonal season 1) was categorized low abundance if compared with plankton abundance in another season. The low value of phytoplankton abundance caused by non upwelling phenomenon and grazing process and the low abundance of zooplankton caused by low rate of zooplankton and predation by Lemuru fish. Phytoplankton and zooplankton abundance had strong relationship with Lemuru fish catched with correlation coefficient value 0.76 and 0.69. This condition caused by phytoplankton and zooplankton are source of Lemuru fish food.]]>

<![CDATA[This study objectives were to investigate the track of shark trade from Bali Province, the exports volume of shark trade during 2015-2016, the length of sharks; species exported in the ETP category; and the effectiveness of shark trade license by BPSPL Denpasar based on EAFM analysis. This study used exploration method with questionnaires, interviews and secondary data from BPSPL Denpasar. The results showed that the track of shark trade started from when the shark is caught by the fishermen which purchased by exporter companies, then they had to get shipment recommendation letter from BPSPL Denpasar and fish health certificate from BKIPM Class I Denpasar, then sharks was brought to I Gusti Ngurah Rai International Airport for final check and ready to be exported to the destination country. During 2015-2016 there were 559 sharks from the species of Carcharhinus melanopterus, Triaenodon obesus, Orectolobus maculatus, Atelomycterus marmoratus, Chiloscyllium plagiosum and Halaelurus maculosus that have been exported to the 12 destination countries. The EAFM analysis of lengths indicated that the shark's size was at a very young until adult age. Meanwhile, the EAFM analysis of ETP species shows there were 4 shark types of Near Threatened, 1 type of Least Concern status and 1 type of Not Evaluated. Finally the result of EAFM analysis on the effectiveness of shark trade license by BPSPL Denpasar showed that the decision was well executed and run effectively, and so far the shark fishery management at Bali Province is applied successfully.]]>

<![CDATA[The purposes of this study were to determine the water quality, concentration and distribution of Hg in the surface water of Banyuasin river estuary. This research was conducted in June 2016 with 26 sampling stations. Measurement of in situ water quality was done using Conductivity Temperature Depth (CTD) multiparameter profiler while Hg metal was measured using Atomic Absorption Spectroscopy (AAS). The data obtained was interpolated by Inverse Distance Weighted (IDW) and then mapped spatially. The results showed that in general the water quality in Banyuasin river estuary still meets the seawater quality standards for marine biota based on KepMenLH no. 51 in 2004. The concentration of Hg in Banyuasin river estuary ranges from 0.001-0.032 mg/L with a distribution pattern that generally increases towards the ocean. The Hg concentration at the Banyuasin river estuary is on the maximum limit and exceeds the quality standard for marine biota.]]>

<![CDATA[Thalassia hemprichii is one of the seagrass as favorite food of two protected herbivores such as Green Turtle and Dugong. The existence of Thalassia hemprichii and knowing the growth rate becomes very important for sustainability of two herbivores. The study was conducted in Tanjung Benoa waters that covering three parts of the coast such as Samuh, Conrad and Tanjung beach in February until March 2017. Thalassia hemprichii leaves growth is observed consist of long and heavy growth (dry weight) and measured leaf age that has been observed such as young, half old and old leaves. The method that used to measure the growth of Thalassia hemprichii is pruning method and determination the research location using purposive sampling method. The aim of this research is explained the growth rate, biomass, and productivity of young leaves, old leaves of Thalassia hemprichii in Tanjung Benoa Bali. Measurement results of Thalassia hemprichii growth between age group of leaves has different young leaves faster growth if compared with the half old leaves and old leaves with average growth is 3.41mm/day indicates that the efficiency of this seagrass growth will decrease as the leaves age. The highest biomass values ??were found in older leaves if compared with young leaves and half-old leaves with average 0.205 gbk/m2 expected because the thick and wide leaf size will produced larger leaf biomass. The highest productivity value is found in oldest leaves in each station with average 0.028 gbk/m2/day expected morphology and different nutrient content in each leaf tissue.]]>

<![CDATA[Benoa Bay is semi- enclosed bay, which has embouchures. The existence of embouchures are able to contribute the Total Suspended Solid (TSS) to the Bay. As the one of pollution parameter, TSS could be influencing the ecosystem of coral reefs, seagrass, and the existence of dissolved oxygen. This research was aimed to know the spatial distribution of TSS on the surface layer in Benoa Bay. Sample was taken on January 2016, in flood and ebb. TSS was analyzed using gavimetry method based on SNI No. 06-6989.3-2004. Spatial distribution was analyzed by interpolation method- Inverse Distance Weighted (IDW). The concentration range of TSS on January in ebb to tide and tide to ebb was 22.44 mg/L to 261.33 mg/L. The highest distribution in flood was dominated in around of embouchures. It was suspected by inputs of suspended matter from land to the bay. In tide to ebb condition, TSS concentration was high in some areas, such as around the embouchures, midlle and mouth area of bay. The high concentration was suspected by pattern of tidal current in Benoa Bay. The pattern of current in ebb was leaving to the mouth of Benoa Bay, therefore the TSS concentration dispersed to the mouth of the bay.]]>

<![CDATA[Benoa bay is one of estuary that located in the Southern part of Bali Island, and as a strategic tourism destination. The increased of the human activity has an important role to give an ecological pressure for the seawater ecosystem in the Benoa bay. Total suspended solid (TSS) and turbidity is one of the important indicators that could be determining the quality of the seawater. As the estuary, Benoa bay received fresh water from the river discharge that also potentially carries any material to the bay. In addition, port activity is also has an important role in contributing a various material to the Benoa bay. From this research, we found that the TSS concentration and the turbidity are higher in the surface water and also in the bottom layer. TSS concentration and the turbidity also varied from the bay mouth trough the line of vessel onto the inner of bay. TSS concentration and turbidity in the bay mouth has a smaller concentration rather than in the inner part of bay. TSS concentration and turbidity in the inner of bay could be caused by the port activity. In addition, seawater circulation is also has an importan factor to contributing the TSS concentration and the turbidity. Sea current would be erroted the seabottom and with the different shape of the topography could be increased the TSS and turbidity.]]>

<![CDATA[Seaweed culture is one of the main marine and fishery commodities which mostly still occupied by coastal community in Badung regency. One of the center areas for seaweed culture development is at Kutuh Beach in Kutuh Village South Kuta District, Badung regency . Kutuh Beach also known as Pandawa Beach that have developed become a tourism area. The development of Kutuh beach as tourism area affect the development of existing seaweed culture activities. Therefore, a study have been done to get scientific information related to the development of seaweed culture in Kutuh coastal water. This research was conducted at in September-October 2016. The data was collected by carrying out measurements directly on the location of seaweed culture of Eucheuma cottonii at Kutuh coastal water. The data collected in this study including the growth of seaweed Eucheuma cottonii and the quality of Kutuh coastal waters, such us nitrat, phosphate, temperature, salinity, pH, and dissolved oxygen (DO). Our study showed that that the quality of Kutuh Pantai waters is still in good condition for the growth of seaweed except Phosphor that can inhibit the growth of seaweed. Instead of phosphor, seaweed can not grow well in the waters of Kutuh Beach because it is eaten by predators and low intensity of sunlight.]]>
