<![CDATA[Mobilitas (termasuk proses desorpsi-absorpsi) logam berat dalam sedimen bervariasi yang bergantung pada asosiasinya pada komponen mineral dan non-mineral sedimen yang dapat juga mengindikasikan pada sumber alami dan non-alami. Penelitian ini bertujuan mengungkap kemungkinan sumber logam berat Cu dan Fe berdasarkan fraksinasi dan total logam. Lokasi penelitian terdiri dari 11 titik yang terbagi menjadi tiga bagian pesisir timur, pesisir barat, dan Pulau Nias, Sumatera Utara. Fraksi geokimia diperoleh berdasarkan prosedur ektraksi bertingkat SEP BCR (Sequential Extraction Process Bureau Commune de Reference of the European Commission) dalam empat fase yaitu: Fraksi terlarutkan asam, fraksi tereduksi, fraksi oksidasi, dan fraksi residual. Total logam diperoleh berdasarkan metode USEPA 3050B. Pengukuran logam dilakukan dengan menggunakan spektrofotometri serapan atom (SSA). Hasil penelitian menunjukkan bahwa kegiatan antropogenik diduga menyumbang logam Fe dalam sedimen yang ditunjukkan oleh konsentrasi non residu (5,55-203,15 mg/kg) yang lebih tinggi dibandingkan fraksi residu (4,89-21,47 mg/kg). Berbanding terbalik dengan logam Cu yang asosiasi tertinggi adalah fraksi residu (2,24-8,85 mg/kg). Logam berat dalam sedimen mendapat kontribusi dari sumber alami dan antropogenik, logam Cu diduga bersumber lebih banyak secara alami dan logam Fe diduga bersumber lebih dominan dari aktifitas manusia (antropogenik) baik sekitar wilayah pesisir maupun kemungkinan berasal dari daratan.]]>

<![CDATA[Flying fish eggs are one of the fisheries commodities that have important economic value in the waters of Tual City. Based on the Decree of the Minister of Maritime Affairs and Fisheries Number 69 of 2016 concerning the Plan for the Management of Flying Fish Fishery, several priority issues that are the problem of flying fish are; (1) fish resources and habitat; (2) social and economic; (3) governance. The flying fish fisheries management plan is expected to support policies in the management of flying fish and flying fish eggs in the Fisheries Management Region of the Republic of Indonesia. The purpose of this study is to analyze the system problem situation and build a model for the development of flying fish egg fisheries. This research method uses system approach. The four-step system approach starts from needs analysis, problem formulation, system identification and system modeling. The results showed that the root problems in flying fish egg fisheries were many ships that did not have permit documents, the availability of data on potential fish resources, the use of fishing gear that were considered environmentally unfriendly, low human resources, high fuel prices and access to capital for fishermen. The model of developing flying fish eggs consists of submodel use of environmentally friendly fishing gear and submodel of the development of flying fish egg fishing business. The problem of flying fish egg fisheries in Tual PPN can be solved by the solution of the use of environmentally friendly fishing gear for flying fish resources and the development of the fly fish egg fishing business.]]>

<![CDATA[The standard of measurement of abalone is very important because it can help to identify accurately abalone shellfish based on shell morphology. This research was aimed to examine the truss morphometric and morphologycal characters of Haliotis squamata intraspecies in the southern coastal Java and Bali. The research was conducted from December 2014 to August 2016. Abalone was collected based on the purposive sampling method, it was then identified. The shellfish of abalone was measured and analyzed by using principal component analysis (PCA), canonical discriminant analysis and cluster analysis. The results showed that PCA was able to separate Haliotis squamata populations from Java and Bali using combination of PCIII and PCIV based on the factor coefficient values. The key characters that separated Haliotis squamata from the population of Java and Bali were the combination of characters BF (0.535) for PCIII and characters CH (0.522) for PCIV. Canonical discriminant analysis showed that Bali was the highest sharing component value (100%) of intra population and also the lowest sharing component of inter population (0%). The highest percentage of similarity was 99.91% that indicated the population of Binuangeun and Pangandaran, while the lowest was 99.31% for the population of Banyuwangi and Bali. The morphological characteristics of Haliotis squamata species in several locations showed specific characters such as color patterns, textures and shapes.]]>

<![CDATA[Fisheries in Semarang City are dominated by small-scale fisheries. This is indicated by the use of the largest fishing fleet of 10 gross tons operating near the coast. This study aims to analyze the status of small-scale fisheries in Semarang City for sustainable management. Sustainable management is management that guarantees the availability of natural resources and environmental services for future generations. The study was conducted for three months, namely September-November 2018 in the coastal waters of Semarang City, which was part of the Fisheries Management Region (WPP) 712. The method used in this study is the analysis of time series surplus production, namely data from the catch (ton/year) and the number of fishing gear (unit) within 10 years (2007-2016), to calculate the catch per-unit effort (CPUE), maximum sustainable yield (MSY), optimum effort (fopt), utilization rate (TP) and capacity level (TK). This study was obtained results of a downward trend in CPUE; the existing fishery catch or production in 2016 has exceeded the MSY value is 479 tons/year (Schaefer) and 439.11 tons/year (Fox); utilization rate of more than 100% which is 108-127% (Schaefer) and 118-138% (Fox), so that small-scale fisheries in Semarang City are at the level of over-exploited. Based on the fopt analysis, the number of fishing gear used (fexisting) has exceeded the optimum effort with a fishing capacity exceeding 100%, so that small-scale fisheries in Semarang City have experienced overcapacity.]]>

<![CDATA[Kabupaten Aceh Barat memiliki panjang garis pantai sekitar 50,55 km, dengan luas perairan lautnya sekitar 80,88 km2. Kondisi ini tidak terlepas dari letaknya yang menghadap langsung ke Samudera Hindia yang kaya akan sumberdaya ikan. Rumpon adalah suatu alat bantu pengumpul ikan yang menggunakan atraktor, seperti daun kelapa, daun pinang dan daun nipah serta benda padat lainnya yang berfungsi sebagai pemikat berkumpulnya ikan. Rumpon hanyut merupakan rumpon yang tidak menetap dan tidak dilengkapi dengan jangkar sehingga hanyut mengikuti gerakan dan arah arus, sedangkan rumpon menetap adalah rumpon yang dilengkapi dengan jangkar atau pemberat. Tujuan penelitian ini adalah untuk menganalisis komposisi jenis, jumlah dan berat ikan hasil tangkapan. Penelitian dilakukan pada bulan Januari-Juli 2018, bertempat di perairan Aceh Barat. Data yang dikumpulkan berupa data primer, dimana pengumpulannya menggunakan metode experimental fishing. Selanjutnya, data tersebut dianalisis secara statistik menggunakan uji t. Pengamatan terhadap hasil tangkapan dilakukan hingga 18 trip terhadap rumpon tali rafia dan rumpon tradisional. Peubah yang diamati pada penelitian ini adalah komposisi jenis, jumlah dan berat ikan hasil tangkapan pada kedua rumpon. Hasil penelitian menunjukkan bahwa rumpon tradisional memperoleh hasil tangkapan ikan sebanyak 7.538 ekor (61,5%) lebih banyak sebanyak daripada rumpon tali rafia sebanyak 4.821 ekor (38,5 %), dengan komposisi jenis ikan hasil tangkapan terdiri dari 7 jenis yang didominasi oleh ikan kembung. Hal ini menunjukkan bahwa rumpon tradisional lebih efektif daripada rumpon tali rafia.]]>

<![CDATA[Seagrass is one of the communities in the intertidal Madasanger. Due to environmental characteristic, this intertidal area is always dynamic mainly is caused by a change of tidal wave. This condition cause habitat for seagrass living often changes. The aim of this study is to analyzed dynamic community of seagrass on the dry season in Madasanger. Seagrass community was observed at two stations parallel to the coastline, such as high tide zone and low tide zone during dry season (April). The seagrass community distributed dynamically based on percent cover and spatial pattern. There are five genera of seagrass such as Cymodocea, Halodule, Halophila, Syringodium, and Thalassia cover the habitat with 36.5-75.67%. During period 2014-2018, the highest percent cover of seagrass was found in 2016. This condition in 2016 is the best environment for seagrass living because of limiting rainfall (input of freshwater). The seagrass habitat lived better mainly Halodule and Syringodium in deeper substrate. The dynamic of seagrass community intertidal Madasanger showed by the sand movement follow up with the changes of seagrass spatial distribution during five years.]]>

<![CDATA[The coastal swamp is a tidal swamp part of the estuary ecosystem. Coastal swamp on the Cimandiri River, Sukabumi West Java is one of the estuarine ecosystems that have an important ecological role for the lives of sedentary aquatic biota and migratory fish such as eels. The objectives of this study were to determine the population biology of eels and influential environmental factors in the coastal swamp of the Cimandiri River. The study conducted partially in September-October 2016, March and December 2017 and January-November 2018. Eel fishing and water quality measurements were carried out in 4 selected locations based on different habitat conditions. Eel fishing is done at night with fishhooks and traps. There were two species of tropical eel, Anguilla bicolor bicolor (107 individuals) and Anguilla marmorata (4 individuals). The total length of A. bicolor bicolor is 15.7-57.0 cm and weight 5.8-347.2 g. The total length of A. marmorata is 17.0-29.5 cm and weight 6.9-33.7 g. The growth pattern of A. bicolor bicolor in the coastal swamp was negative allometric, with the condition factor values 0.99-1.03. Based on Principal Component Analysis (PCA), the preferences for the presence of eel in coastal swamp are characterized by parameters of depth, transparency, salinity, and water current. From this study, it is known that the coastal swamp has functioned as a habitat for yellow eels in the estuarine phase.]]>

<![CDATA[Perairan laut Bengkulu memiliki potensi perikanan cukup melimpah. Potensi tersebut dipengaruhi oleh beberapa parameter oseanografi. Penelitian ini bertujuan untuk menentukan variabilitas spasial dan temporal parameter oseanografi serta mengetahui hubungannya terhadap hasil tangkapan ikan selama lima tahun di perairan laut Bengkulu. Metode yang digunakan adalah analisis deskriptif berdasarkan visualisasi data kecepatan angin, suhu permukaan laut dan salinitas pada tahun 2011 – 2015. Analisis data dilakukan dengan menggunakan software GrADS, Panoply dan ArcGIS. Hasil penelitian menunjukan tangkapan ikan terbanyak 16.514 ton terjadi pada musim barat tahun 2015 dengan kecepatan angin 1,211 m/s, SPL 29,094 oC dan salinitas 33,623 psu. Sedangkan hasil tangkapan ikan terendah terjadi pada musim barat tahun 2012, yaitu sebesar 7.576,60 ton. Kondisi oseanografi perairan pada musim tersebut untuk parameter kecepatan angin 4,624 m/s, suhu permukaan laut 28,765 oC, dan salinitas rata-rata 33,987 psu. Hubungan kondisi oseanografi terhadap hasil tangkapan ikan secara umum yaitu hasil tangkapaan ikan cendrung rendah pada kondisi kecepatan angin dan salinitas yang tinggi, SPL rendah. Sebaliknya jika kecepatan angin dan salinitas rendah, SPL tinggi maka akan didapatkan hasil tangkapan ikan yang banyak.]]>
