The objectives of this study were to determine the harmful species of dinoflagellates, to determine the concentration of nutriens in surface waters, and to analyze factors affecting the ecological aspects of the harmful dinoflagellates. The results showed that there were 7 genus of dinoflagellates found in this study i.e., Ceratium spp., Gymnodinium sp., Dinophysis sp., Gonyaulax sp., Noctiluca sp., Protoperi-dinium spp., and Peridinium sp. Protoperidinium spp. and Ceratium spp. were the predominant species, with their abundance ranged of 9-659 cells/L and 6-556 cells/L, respectively. In temporal scale, values of DO and water light penetration were not significantly different (α>0.05), while for the parameter of nutriens, salinity, and abundance were significantly different (α<0.05). Total abundance of dinoflagellates was significantly correlated with nitrate, nitrite, ammonia, phosphate, salinity, and DO. Harmful dinoflagellate species such as Dinophysis sp. (DSP), Gymnodinium spp. (NSP and PSP), Noctiluca sp. (anaerobic), and Gonyaulax sp. (anaerobic) were observed in the study area. The high concentration of ammonia (>1 mg/L) in the waters of Losari beach also indicated that the area was affected by anthropogenic activities. Minimizing nutrient inputs from the land was becoming the most priority measure to be done to avoid such effects related to dinoflagellate harmful algae bloms.Keywords: anthropogenic, dinoflagellates, harmful species, Makassar, nutrients.

ABSTRACTMangrove ecosystem in some regions of the Bintan Bay has suffered damage due to development of human settlements, developing of land transport infrastructure, and also logging by the community. The aim of this study was to assess the level of damage, factors affecting the damage, and to calculate the estimated value of claims for damaged mangrove ecosystem in the Bintan Bay, Bintan District. The results showed that mangrove vegetation in Bintan Bay consists of 16 species. Based on the analysis of standard criteria and guidelines for mangrove destruction KEPMENLH 201, 2004, the quality of mangroves in Bintan Bay was considered in a good criteria (very dense and medium) and damaged criteria (rare). The observation of satellite images from 1990 to 2013 showed that mangrove area decreased by 501.39 hectares or 27.1%. Contributing factor due to the decrease of mangrove trees was to fuel the manufacture of charcoal, construction of infrastructures such as roads, ports of fishing boats and also the establishment of the fish pond. Based on rehabilitation application scenario for 15 years, the total area of compensated mangrove due to its damage was 1091.727 hectares with rehabilitation cost of about Rp 30.372.391.000,00. Meanwhile, for 30 years scenario rehabilitation, the total damage mangrove area that should be compensated was 1743.406 hectares. Keywords : Bintan Bay, mangrove ecosystem, estimated value damage claims

Vulnerability analysis is one of the methods for determining effective management of coastal and marine resources. Seribu islands potentially affected due to oil spills. The oil spills incident in this area caused by shipwreck from traffic on Tanjung Priok port and ALKI 1, as well as accident of petroleum exploration and exploitation. At least, oil spills in Seribu Islands have been recorded since 2003, 2004, 2006, 2007 and 2008. This study aims to calculate the vulnerability index of Pramuka island and Belanda island in the Seribu Islands. This research was conducted by using a theoretical approach of vulnerability (V), which is a function of exposure (E), sensitivity (S) and adaptive capacity (AC). The parameters in exposure category are tidal type, tidal range, wave height, substrat type, and water depth. Parameters in sensitivity category are growth type of reef, slope, protected ecosystem, coverage percentage, coral density, protected species, and fish abundance. Parameters in adaptive capacity are oil spill contingency system, conservation institution, community response, and economic dependence. Data of each parameter were transformed into a score ranging from 1 to 5. The formula of vulnerability index using addition and subtraction model where; V = E + S – AC. The results indicate that Seribu Islands have vulnerability status from moderate to high, which 4.15 for Pramuka island and 6.39 for Belanda island.

Ecological resilience is an important property of natural ecosystem to be understood in coral reef management. Resilience of Indonesian coral reefs was assessed using 2009 COREMAP data. The assessment used 698 data of line intercept transects collected from 15 districts and 4 marine physiographies. Resilience index used in the assessment was developed by the authors but will be published elsewhere. The results showed that coral reefs at western region had higher average resilience indices than eastern region, and Sunda Shelf reefs had higher resilience indices than coral reefs at Indian Ocean, Sulawesi-Flores, or Sahul Shelf. Four districts were found to have coral reefs with highest resilience indices, i.e. Bintan and Natuna (western region), and Wakatobi and Buton (eastern region). Raja Ampat had coral reefs with lower average resilience indices than that of Wakatobi. Uses of resilience index in coral reef management should be coupled with other information such as maximum depth of coral communities.

Gugus pulau Togean memiliki potensi sumberdaya perairan yang dimanfaatkan untuk kegiatan wisata bahari. Peningkatan kunjungan turis pada periode tertentu menyebabkan aktivitas wisata dan kegiatan terkait meningkat, sehingga berpengaruh terhadap penurunan kualitas perairan dan obyek wisata. Penelitian ini bertujuan untuk mengkaji keterkaitan antara musim kunjungan turis dalam setahun dengan perubahan yang terjadi pada beberapa parameter kualitas perairan laut di sekitar kawasan obyek wisata. Metode analisis yang digunakan adalah PCA (Principal Component Analysis) dan analisis IPL (Indeks Pencemaran lingkungan). Hasil penelitian menunjukkan bahwa peningkatan kunjungan turis menyebabkan peningkatan nilai BOD5, COD, dan NH3 serta penurunan nilai DO di perairan. Nilai korelasi keempat parameter tersebut lebih tinggi pada bulan Nopember dibanding Juli, dan merupakan komponen parameter pembentuk sumbu utama pertama di kedua musim. Peningkatan nilai kekeruhan, penurunan salinitas dan suhu pada bulan Nopember dibanding bulan Juli karena terkait dengan musim penghujan dan gelombang yang tinggi. Indeks pencemaran lingkungan perairan meningkat 21,05% selama musim puncak kunjungan turis, namun secara umum perairan gugus Pulau Togean masih dalam kategori belum tercemar. Kata kunci : kualitas perairan laut, aktivitas wisata, Gugus Pulau Togean Marine resources of Togean Islands have been used for tourism activity. The increasing number of tourist in certain period every year has lead to increasing of tourism activity and its related activity. This condition probably effects sea water and habitat qualities. This research aim to studied correlation between tourist season in one year and the change of marine water quality parameters in tourism area. The data were analyzed using PCA (Principal Component Analysis) and EPI(environmental pollution index). The result showed that BOD5, COD, and NH3 increased while DO decrease during the peak season of tourism activity. The correlation value of those four parameters was relatively higher in November than in July. Those parameters were the component that forms the main axis in both seasons. The increasing of turbidity and decreasing of salinity and temperature in November rather than in July were correlated with rainy season and high wave. Water pollution index increasing during peak season of tourism activity, but in general, marine water quality of Togean Islands can be categorized as good (not yet polluted) based on water pollution index. Key words: sea water quality, tourism activity, Islands Togean

Tingginya suhu buangan air pendingin PT. Badak NGL yang dilepas ke Perairan Bontang menyebabkan terganggunya berbagai sumberdaya pesisir yang ada disekitarnya. Karena itu perlu diketahui pola sebaran suhu agar dampak yang mungkin timbul dapat diminimalkan. Penelitian ini bertujuan untuk memprediksi pola sebaran suhu dari buangan air pendingin PT. Badak NGL di Perairan Bontang, Kalimantan Timur. Prediksi dilakukan dengan menggunakan model hidrodinamika dan transpor suhu 3-D yang dimodifikasi dari model POM (Princeton Ocean Model). Gaya pembangkit yang digunakan dalam model adalah pasang surut, debit buangan air pendingin dan debit sungai. Pemilihan langkah waktu (t)=0,5 detik, dengan 118 grid (barat-timur) dan 187 grid (utara-selatan), ukuran grid Δx=Δy=30 m. Nilai awal : u=v=ζ=0, T0 = 28 °C dan S0 = 32 ‰. Verifikasi elevasi dan suhu antara hasil model dengan hasil pengukuran menunjukkan kesesuaian yang baik dengan nilai korelasi 0,97 dan Kesalahan Relatif Rata-rata (Mean Relative Error/MRE) 1,31% untuk verifikasi elevasi, korelasi 0,90 dan MRE 5,17% untuk verifikasi suhu permukaan pada saat bulan purnama serta korelasi 0,87 dan MRE 7,12% saat bulan perbani. Hasil simulasi menunjukkan perbedaan pola sebaran suhu permukaan paling ekstrim ditemukan pada saat purnama untuk kondisi cuplik pasang maksimum dan surut maksimum. Perbedaan terutama terlihat pada Stasiun 8 (Muara Kanal Pendingin) yakni 41 °C saat surut maksimum dan saat pasang maksimum (ΔT=6 °C). Adapun perbedaan suhu antara lapisan atas dan lapisan bawah yang cukup besar ditemukan di Stasiun C yakni sekitar 2,54 C saat untuk skenario musim kemarau dan 2,32 C untuk skenario musim hujan Kata kunci : POM, buangan air pendingin, sebaran suhu, debit sungai, model numerik, Perairan Bontang High temperature of cooling water discharge of PT. Badak NGL that released to Bontang waters caused disturbances to the coastal resources in its surrounding. Therefore, it is urgent to understand the pattern of thermal dispersion in order to minimize the possible impacts occurred. This research was aimed to predict the pattern of thermal dispersion from cooling water discharge of PT. Badak NGL in Bontang waters, East Kalimantan. Prediction was done using hydrodynamic model and 3-D thermal transport modified from POM (Princeton Ocean Model). Driving forces used in this model were tides, flows of cooling water discharge and rivers discharge. Choice of time step (t)=0.5 second, with 118 grids (west-east) and 187 grids (north-south), grid size Δx=Δy=30 m. Initial value : u=v=ζ=0, T0 = 28 °C and S0 = 32 ‰. Verification of elevation and temperature between results of models and direct measurement showed a good suitability with correlation value was 0.97 and Mean Relative Error (MRE) 1.31% for elevation verification, correlation 0.90 MRE 5.17% and correlation 0.87 MRE 7.12% for thermal verification during spring and neap tides, repectively. Results simulation revealed the most extreem difference in pattern surface thermal dispersion that found during spring tide for sampling condition of maximum tide and ebb. Distinct difference was especially found at station 8 (mixing point) i.e. 41 °C during maximum ebb and 35 °C during maximum high tide. Whereas, significantly high thermal difference between upper layer and bottom layer was found at station C i.e. around 2,54 °C for dry season scenario and 2,32 °C for wet season scenario Key words: POM, cooling-water discharge, thermal dispersion, rivers discharge, numerical model, Bontang waters

Pulau-pulau Krakatau memiliki dinamika secara geomorfologi, dan berbagai perubahan fisik yang berlangsung memberikan dampak terhadap biota, termasuk pada proses dan tingkat pergantian suksesi komunitasnya. Tujuan penelitian ini untuk menjelaskan kondisi terkini dan proses kolonisasi komunitas karang, termasuk status kerusakan komunitas karang dan disturbansi lingkungan yang mempengaruhinya. Line intercept transect dilakukan di enam stasiun pada dua kedalaman yang berbeda yakni 5 dan 10m. Sedangkan observasi terhadap komunitas koral dilakukan dengan perekaman video. Hasil penelitian ini menunjukkan bahwa suksesi atau perkembangan komunitas (i.e. kolonisasi) karang yang dijumpai di Pulau Anak Krakatau masih mengindikasikan tahap awal kolonisasi, berbeda dengan komunitas karang yang dijumpai di Pulau Rakata dan Panjang. Diversifikasi komunitas karang di kedua pulau tersebut, menunjukkan dominansi spesies oportunis dan pioner (i.e. Pocillopora dan Seriatopora) yang umum dijumpai di Anak Krakatau sudah tergantikan. Dominansi dari beberapa spesies karang telah mengindikasikan terjadinya proses eksklusi kompetitif di antara komunitas karang. Tiga tipe komunitas karang yang dijumpai dapat dibedakan menurut karakteristik masing-masing kawasan, yaitu komunitas kawasan terpapar, semi terpapar/terlindung, dan terlindung. Kerusakan komunitas karang di Krakatau berdasarkan kriteria indeks kerusakan karang (CDI) sudah termasuk kedalam kategori wilayah “hot spot”, dimana sangat memerlukan perhatian, pengawasan, pengamatan atau restorasi komunitas karang. Hasil penelitian ini memberikan gambaran bahwa terjadinya kolonisasi dan tingkat kerusakan komunitas karang perlu menjadi acuan dalam pengelolaan kawasan terumbu karang di Cagar Alam Laut Krakatau. Kata kunci: kolonisasi, suksesi; komunitas karang; pengelolaan; Krakatau Krakatau Islands diversity is geomorphologically dynamic, and these physical changes influence on organisms including community successional. The purposes of this research were to determine the condition and describe the recent colonization development of coral communities in the Krakatau Islands after sterilization. Transects were done at six stations at two different depth (i.e. 5 and 10 m) using line intercept transect. While observations of coral communities were done with video transect. This study showed that succession or development of coral communities (i.e. colonization) that found in Anak Krakatau indicated earlier stage of colonization. It has different coral communities compared with those that found in Rakata and Panjang island. The diversification of coral communities on both islands, showed that opportunistic and pioneer species (i.e. Pocillopora and Seriatopora) that generally found in Anak Krakatau has been replaced. There are indications of dominance may already take place through competitive exclusion in the coral communities. Three community types were distinguished based on characteristics for each sites, as follows: communities of wave-exposed habitats, communities of semi- exposed to sheltered habitats, and communities of sheltered habitats. The extent of coral damage covered all six sites based on coral damage index (CDI). This suggests that of the all transects were "hot spots'' that required management action. These results indicate that colonization and the level of coral damage have to be taken into account on the manegement of coral ecosystem in the region. Keywords: colonization; succession; coral communities; management; Krakatau
