Keberadaan daerah penangkapan ikan di perairan akan selalu bersifat dinamis, selalu berubah atau berpindah mengikuti pergerakan kondisi lingkungan, yang secara alamiah ikan akan memilih habitat yang lebih sesuai. Zona tangkapan ikan Tuna yang diprediksi dapat dilakukan dengan mendeteksi distribusi klorofil-a dan distribusi suhu permukaan laut dari citra Aqua MODIS. Penelitian ini bertujuan untuk memprediksi zona lokal penangkapan ikan tuna di laut sekitar kota Bitung, berdasarkan distribusi klorofil-a dan suhu permukaan laut dengan menggunakan citra satelit Aqua MODIS data level-3. Serangkaian kegiatan penelitian yang dilakukan secara bertahap adalah: koleksi gambar, pemotongan gambar sesuai dengan area yang diinginkan, ekstraksi gambar, interpolasi data, overlay peta, dan terakhir adalah tata letak peta. Hasil dari Suhu Permukaan Laut (SST) dan konsentrasi klorofil-a di perairan laut Bitung dan sekitarnya menunjukkan klorofil-a dan suhu permukaan laut bervariasi setiap musim. Distribusi klorofil-a tertinggi adalah pada musim peralihan kedua pada bulan September dan terendah di musim barat pada bulan Desember. Distribusi suhu permukaan laut tertinggi adalah di musim timur pada bulan Juni dan terendah di musim timur pada bulan Agustus. Hasil penelitian menunjukkan pada beberapa titik penangkapan ikan Tuna yang paling potensial pada musim peralihan II dimana setiap bulan di musim tersebut berpotensi membentuk daerah penangkapan Tuna.

Analysis of health risk due to lead (Pb) exposure in marine biota on the community around Kendari BayPurpose: To understand the risk level of health problem because of the lead exposure found on fish and shellfish that was consumed by community around Kendari bay.Methods: This study was an analytical observational through a cross sectional study design by combining Environmental Health Risk Analysis (ARKL) and Environmental Health Epidemiology (EKL) approaches. Population around Kendari bay was taken using proportional sampling criteria. The marine biotas in this study were 30 fish samples of 3 kind of most consumed fish and shellfish from 6 fishponds in Kendari bay. Measurement of lead content on it was made by Atomic Absorption Spectrometry (AAS).Results: The results of the study shows the lead content on fish and shellfish were 0,0027-0,0095 mg/kg and 0,1026-0,1097 mg/kg respectively while intake rapidity of fish and shellfish 0,0051 mg/kg/day and 0,016 mg/kg/day respectively. Health risk level of consuming contaminated fish was 1.29 while the contaminated shellfish was 4.03.Conclusions: The community around Kendari Bay has a risk of health problems (RQ> 1) due to lead exposure, therefore it needs to be controlled.

Ambon Bay waters consist of two parts, Inner Ambon Bay and Outer Ambon Bay separated by a gap that is narrow and shallow. Ambon Bay has a lot of functionality and USAbility both in transportation, conservation, and tourism. The existence of one of the sites SS. Aquila sinking ship that sank since May 27, 1958, became one of the tourist attraction diving in Ambon Bay. Determination of water pollution index Ambon Bay becomes very important to do as support material and development of sea travel. Determining pollution index is done by direct measurement using the sea water quality parameters Water Quality Checker (DKK TOA WQC Type-24), as well as laboratory analysis to determine the chemical parameters of seawater (pH, TSS, salinity, turbidity, oil, grease). The results showed that the waters of the Bay of Ambon Affairs based on some parameters water quality standard for marine tourism is still included in accordance with the standard criteria by Keputusan Menteri Negara Lingkungan Hidup Nomor: 51 Tahun 2004 on Guidelines for Determination of Water Quality Status.

Lactic acid bacteria (LAB) generally accepted as safe microorganism and play an important role in the fermen-tation and preservation of food/feed. LAB is known to extend the shelf life of food/feed, because of its ability to produce antibacterial compounds such as lactic acid, hydrogen peroxide and bacteriocins. The objective of this study was antibacterial compounds produced by Lactobacillus plantarum and their application for fish preserva-tive. The research results showed L. plantarum [Su-ls520, Su-ls530, Su-ls537] produces lactic acid from 71.16 to 77.91mg/mL, hydrogen peroxide from 0.17 to 0.25 mg/mL and producing bacteriocins indicated by the pres-ence of the gene encoding plantaricin, an antibacterial compounds that act as food preservative. Lactic acid 1.5% and 3% salt was not able to suppress the growth of bacteria, while fermentation solution (supernatant) of L. plantarum [Su-ls520, Su-ls530], chitosan 1.5% and a mixture of lactic acid 1.5% and salt 3% slightly sup-press the growth of spoilage bacteria on the fish material stored 48 hours at room temperature. Treatment with fermentation solution (supernatant) of L. plantarum Su-ls537 able to suppress strongly growth of spoilage bac-teria in fish material for 24 and 48 hours storage. At 72 hours of storage the fish material rotted, the addition of preservatives no longer able to suppress the growth of spoilage bacteria.

This study aimed to assess fish diversity and its related aspects in the Sawal Mountain Region, the watershed Citanduy in Ciamis, West Java, Indonesia. The study was conducted by grouping into four zones based on forest condition and the order of the river. The fisheswere sampled by using elektrofishing. This study recorded 12 species which Barbodes binotatus is the most abundant and widely local distributed, i.e. 20.09 individu/station and occupied 78.60 % of the area. Based on species status, as much as 75% species have wide geography distribution (common species) and the rest was introduced species. As much as 50% (6 species) have the potency as consumption fish, 25% (3 species) as ornamental fish, 17% (2 species) both as ornamental and consumption, and 8% (1 species) is stil unknown for the benefit.

Throughout the past decades, the legal framework governing Indonesia's maritime regime has experienced various changes. This is apparent during the enactment of the 1957 Djuanda Declaration and the 1982 UN Convention on the Law of the Sea (UNCLOS) when the novel concept of archipelagic State was introduced. This paper reviewed the historical development of this concept up until the recent issue of designating archipelagic sea lanes (ASL) in Indonesia. Dubbing this issue as the epilogue of Indonesia's journey towards archipelagic statehood, this paper focuses on (1) the importance of designating ASL for archipelagic States, (2) the kind of considerations that pose challenge to its designation and (3) how these challenges have particularly affected Indonesia's reluctance to open ASL routes which are Internationally sanctioned, particularly with regards to the East-West route. This paper found that such hardship stems from the lack of clarity in relevant UNCLOS clauses on archipelagic States as well as from the inherent rivalry between flag and coastal States. Security concerns have also been crucial in explaining Indonesia's reluctance to fully abide by International demand. The paper ended with some possible pathways and policy recommendations that Indonesia may take with regards to its ASL regime.

Sea surface temperature (SST) is one of the parameters which can be used to detect the potential of fish distribution in the sea. One of method which can be used to measure the SST to utilize remote sensing satellite imagery. The data used in this study are the Aqua, Terra and NOAA satellite imagery from 2010 until 2012. This study purpose is to find out the value of SST in the northern region of Papua in 2010 to 2012 from satellite imagery and also to compare the satellite imagery with Buoy data as a field validation data.The methode of processing is used a script programming language by using the programming software which built to get the SST value by compiling data. The next step when the previous processing result has out are selecting the data, emulating the time between the satellite imagery with the Buoy Data, average monthly and yearly SST calculation, noise and RMSE value calculation, making the graphic and scatterplot, and also the depiction of SST distribution maps.The result shows the value of SST in northern Papua has decreased every year with a random pattern. From the three satellite imagery which are used in this research, NOAA imagery is the most imagery which can represent the condition of the SST on real field. It is due to the value of the noise and RMSE on NOAA are about -0.43 and 0.2228. Based on statistic test, there is a correlation between the Aqua, Terra and NOAA imagery and Buoy Data. Then, there is a difference between the value of the average SST temperature data from satellite imagery and Buoy with a confidence level of 95%.

This research was carried out on July-August 2016 in the villages of Apengsala, Mohongsawang and Balehumara in SITARO District of North Sulawesi Province. It aims to make inventory of fish species, record the number of the fish caught, and get the local fishermen profile. Samples were bought from local fishermen who just returned from fishing areas in the traditional fish market “Burias”. The data of fishermen profile and fishing gears were retrieved from 30 respondents of Apengsala, Mohongsawang and Balehumara fishermen. Based on the results of the identification, interviewing and questionnaire filling, the conclusions are as follows: 1) there are 23 species of fish usually captured by local fishermen. 2.) there are 5 types of fishing gears often used by fishermen : Spear gun (Jubi), “ Darape” net (soma darape), traps (bubu), “Rawai” Rod (pancing rawai) and “Cang” net (soma cang). 3.) The average age and the length of fishing profession from 30 respondents data, ranges from 27-60 years old and 4-41 years of profession (Apengsala) ; 32-50 years old and 9-31 years of profession (Mohongsawang) ; and 20-65 years old and 1-41 years of profession (Balehumara). Only 1 respondens who is not married yet, mostly finished their study until elementary school, and only 9 respondents have odd jobs. Local fishermen can still meet the needs of the family life with a dependent varied with 3-7 person/family.
