Teluk Jakarta merupakan perairan yang memiliki nilai ekonomis yang sangat tinggi karena posisinya yang berada di Ibu Kota Indonesia namum perairan ini juga memiliki beban masukan yang tinggi mulai dari kegiatan domestik, industri, ataupun pertanian dari 13 muara sungai di sekitarnya yang berasal dari wilayah Jakarta, Bogor, Tangerang, dan Bekasi sehingga dapat memberikan dampak terhadap kelimpahan klorofil-a. Permasalahan kini muncul karena konsentrasi total material tersuspensi yang melebihi daya dukung perairan mendorong produktifitas seperti plankton untuk berkumpul dan tumbuh dengan sangat cepat sehingga menyebabkan eutrofikasi. Atas dasar tersebut, peneliti melakukan penelitian di Teluk Jakarta dengan tujuan : (1) Menganalisis hubungan Total Suspended Matter (TSM) dan klorofil-a case 2 (CHL2), (2) Menganalisis hubungan parameter fisik kelautan terhadap kesuburan di teluk Jakarta, serta (3) Mensintesis hubungan seluruh variabel penelitian terhadap kesuburan. Data yang digunakan adalah data bulanan dari seluruh data dari sensor OLCI-A yang tersedia di GlobColour Project yaitu bulan April 2016 - Desember 2018. Seluruh data diolah menggunakan metode SIG  secara time series untuk mengetahui karakter masing masing variabel terutama terkait pada bulan angin muson. Selanjutnya digunakan analisa regresi linear, uji-F, dan uji-T untuk mengetahui hubungan terhadap variabel penelitian. Hasil yang diperoleh antara lain terdapat  hubungan yang sangat kuat antara TSM dan CHL2 dengan nilai R = 0,905 dan nilai P= 0,000 < 0,05, parameter kelautan yang dominan terhadap kesuburan adalah parameter arus laut terutama pada musim barat, variabel penelitian dengan variansi searah kuat yaitu CHL2 dengan TSM dan arus laut, variansi berkebalikan kuat dengan curah hujan dan temperatur.

Jakarta bay is a water that have high economic value because of its position in the Indonesian capital city, but these water also have a  high input load due to domestic, industrial, or agricultural activities from the surrounding river estuaries comes from Jakarta, Bogor, Tangerang, and Bekasi regions that can have an impact on the high concentration of chlorophyll-a. The problem comes when the concentration of TSM exceeds the carrying capacity of the water thus encouraging plankton to grow and develop rapidly so it can cause eutrophication . Based on this, the author conducted research in the Jakarta bay with the following objectives: (1) Analyzing the relationship of TSM and Chlorophyll-a Case 2 (CHL2), (2) Analyzing the relationship of marine physical parameter to productivity in Jakarta bay, and (3) Synthesize the relationship of all data variables to productivity. Data collection was conducted in April 2016 – December 2018 using monthly data from OLCI-A sensors available at GlobColour project. All data were processed using the GIS and time series method to determine the character of each variable, especially related to Monsoon. Furhermore, linear regression analysis, F-Test and T-Testwere used to determine the relationship to the research variables. The result obtaineda very strong relationship between TSM and CHL2 with R value 0,905 and P value 0,000<0,05, in the marine physical parameters, the dominant parameter was sea current that distribute productivity. Research variables that have a strong relationship were CHL2 with TSM, current velocity, rainfall, and temperature.

"Detects the sound frequency range of fish, the intensity of the sound amplitude, sound fluctuations, and shape the sound patterns of the fish. Passive acoustic methods used to monitor marine mammals expressed. In general, the signal obtained from the animal record sounds is poor and difficult to determine from which directions it is produced, therefore it requires that require amplification strengthening. Bioacoustic research is needed to identifies the communication language (Acoustic communication) in mammals. Bioacoustic detect mammal produced frequency ranges of sound, amplitude intensity of sound, voice fluctuation, and form sound patterns of mammals. Studying bioacoustic is inseparable from the science of underwater acoustics, biology of mammals, and the study of mammalian behavior: Generally bioacoustic include physiology of mammals organ that produce sound, earning voice mechanism, sound characteristics of mammals, mammals sound approaching mechanism, the hearing capacity of fish, and the evolution of the auditory system, and to obtain the fequency range of each sound produced by the dolphins (mammals). Environmental conditions and parameters (salinity and temperature) will greatly affect the value of the intensity and frequently generated the target, the more extreme the environmental conditions, the lower value of the intensity and frequency generated."

"ABSTRACTMercury and arsenic are considered to be among the most toxic metals and have been associated with serious adverse health effects. These two trace metals and other contaminants that are found in fish products are therefore of public concern for food safety reasons. Hence, we selected three marine species to study i.e., yellow fin tuna, marlin and green mussels because of their economic values in the international and local markets. The objective of our study was to determine the arsenic and mercury content in these three marine species as a first step in monitoring metal content in seafood products. The tissue samples of tuna and marlin were collected from the Jakarta Fishing Port, while the green mussels was collected from aqua culture sites in Jakarta Bay. The metal content was determined by ICP MS and validated using CRM DORM Z and DORM 3. The speciation of arsenic (organic and inorganic forms) was determined using HPLC ICPMS. All measurements were based on dry weight samples. The result showed that the mercury concentration in yellow fin tuna, marlin and green mussel samples was 0.68 :1: 0.08 mg kg", 0.56 :1: 0.06 mg kg"and 1.51 :t 0.10 mg kg, respectively. The total arsenic concentration in yellow fin tuna, marlin and green mussel samples was 3.47 i 0.21 mg kg, 2.71 i 0.18 mg kg, and 6.77 :t 0.32 mg kg, respectively. The mercury content in the fish tissue was below the maximum allowable concentration (National Standard of Indonesia 1.0 mg kg), except for the green mussels. For total arsenic concentration, all the samples were above the national standard concentration (1.0 mg kg). The organic arsenic species arsentobetaine (AB) found in tuna and marlin fish samples was not toxic. Inorganic and organic arsenic was found in the green mussel samples. Our results suggest that there is a need to establish a national program to regularly monitor the content of selected trace metals in fishery products."

"ABSTRACTFishing activities currently require good management, in order to meet the protein needs of the community. Knowledge on the distribution pattern of fishes related to the condition of marine waters is one way of good management efforts. Several oceanographic parameters that can affect the distribution of fishes are SST (Sea Surface Temperature), chlorophyll a, salinity, and others. Each type offish has different optimal level of particular oceanographic parameters. The distribution of oceanographic parameters are effected by West monsoon, East monsoon and the season inbetween. Therefore, by studying oceanographic parameters on a regular basis, we can determine the fishing areas."

"ABSTRACTMECHANISM OF GENETIC DISORDER AND MUTATION ON BIVALVES INFLUENCED BY LEAD. Bivalves have a feeding mechanism of suspension-feeder or deposit-feeder or both, making bivalves consume the material contained in either beneficial or toxic water. Bivalve can survive even with the condition of polluted waters, including the concentration of heavy metals that exceed a specified threshold. Lead is one type of harmful pollutants originating from anthropogenic activities and contaminated marine waters. The purpose of this paper is to provide knowledge about the process or mechanism of bivalves to defend itself against lead, which can be found in their environment, especially genetic disorders and mutations that may be experienced by marine bivalves as a result of exposure to lead."
