ABSTRACTDissolved and particulate heavy metals play a role in geochemical cycle as an agent in adsorption-desorption, deposition-resuspension, and dispersion mechanisms of heavy metals in water environment. The objectives of this research were to determine the distribution and behaviour of dissolved and particulate heavy metals Pb and Zn in different seasons (west and east seasons) at Jeneberang Estuary of Makassar. Concentrations of Pb and Zn were analysed using Atomic Adsorption Spectrophotometry based on APHA, AWWA, WEF (2005). The concentration of dissolved Pb in the riverine, estuarine, and marine waters were in the range (average) of <0.002 mg/L (below detectable limit), 0.013-0.144 mg/L (0.047 mg/L), 0.016-0.198 mg/L (0.079 mg/L); and the concen-tration of dissolved Zn were in the range (average) of <0.002 mg/L (below detectable limit), <0.002-0.014 mg/L (0.005 mg/L), <0.002-0.083 mg/L (0.017 mg/L). Meanwhile, the concentration of parti-culate Pb were in the range (average) of 1.807-2.569 mg kg-1 (2.215 mg kg-1), 0.521-1.272 mg kg-1 (0.911 mg kg-1), 0.465-2.182 mg kg-1 (1.033 mg kg-1), and the concentration of particulate Zn were in the range (average) of 19.151-90.942 mg kg-1 (51.710 mg kg-1), 16.999-63.059 mg kg-1 (31.694 mg kg-1), 19.439-80.283 mg kg-1 (45.554 mg kg-1) in the riverine, estuarine and marine waters, respecti-vely. Behaviour of dissolved heavy metals Pb and Zn showed that the concentrations tended to increase (desorption) along the gradient of high salinity as a result of the higher heavy metals input from coastal region than that riverine regimes.Keywords: distribution, behaviour, dissolved, particulate, heavy metal, Jeneberang Estuary

The presence of cohesive sediment in the water column can reduce light penetration and affect photosynthesis process, and it can be disrupted the primary productivity of aquatic, and sedimentation of coastal waters. The objective of this research was to determine the cohesive sediment distribution pattern and the relationship with sedimentation. MIKE 3 FM modeling was used to understand the process of sediment transport and sedimentation on Inner Ambon Bay. Sediment transport modeling method was divided into two stages: the hydrodynamic modeling (baroclinic) and sediment transport (mud transport) modeling. The model results indicate current patterns in the Inner Ambon Bay is influenced by the tidal factor. Suspended sediment dispersed vertically from the surface to a depth of 30 m with concentration of about 3.5-15 Kg/m3. The maximum consentration of the suspended sediment occurs at head of the bay (around Waiheru, Passo, and Lateri). Model simulations for 30 days showed the rate of erosion is about 1.04-6.15 Kg/m2/s, while in Inner Ambon Bay the erosion about 9.07x10-8Kg/m2/s only occurred in T1 station. Sedimentation associated with the cohesive sediment accumulation and it was shown by bed level. In addition, the simulation showed bed level in sill ranged at 0.01-0.19 cm and 0.47 mm/day on average, while in the Inner Ambon Bay it ranged from 1.75-10.01 cm, and the sedimentation rate was approximately 39.9 mm/day.

Mangrove restoration is really needed for restoring its ecosystem functions, so that it could be able to support fisheries activity and to protect coastal by extreme weather. In addition, mangrove is able to accumulate sediment that important in protecting the coastal area from sea level rise. Therefore, the aim of this study is to investigate sediment accumulation rate in mangrove area during post restoration. Sampling location were divided into three different stations based on estimated restoration ages, such as ≥ 15 years old (Station 1), 4 - 10 years old (Station 2) and 2 - 8 years old (Station 3). Sediment cores were carried out by inserting 7.6 cm diameter and 100 cm length of polyvinyl chloride pipes. Sedimentation rate is measured by using Pb-210 radionuclide analysis. The results show that the sediment accumulation rate in the last 20th years from all station ranges from 0.17 to 0.42 g/cm2/year. The highest accumulation rate is found at oldest year old station while the lowest accumulation rate is found at younger year old station of mangrove restoration area. Restoration process is clearly able to recover the mangrove’s role in trapping sediment in coastal region. Keywords: sediment accumulation, mangrove restoration, Lembar Bay- Lombok Island

Laut Sulawesi merupakan salah satu jalur penting perlintasan Arus Lintas Indonesia (Arlindo) yang memiliki energi pasang surut internal yang kuat. Arus pasang surut tinggi yang berinteraksi dengan topografi yang kasar akan menciptakan gelombang internal yang kuat. Disipasi dari pasang surut internal akan menyebabkan terjadinya percampuran yang akan memberikan efek penting untuk sistem perubahan iklim dan sumber daya laut. Tujuan dari penelitian ini adalah untuk mengkuantifikasi dinamika dan energetik gelombang internal di Laut Sulawesi dengan pendekatan pemodelan laut tiga dimensi NEMO. Hasil penelitian menunjukkan bahwa gelombang internal dibangkitkan pada daerah Kepulauan Sulu dan Sangihe-Talaud dengan nilai konversi energi lebih dari 10-3Wm-2 dan berpropagasi masuk ke area basin Laut Sulawesi. Disipasi energi yang terjadi pada pusat pembangkitan berkisar 10,8 GW dan berpopagasi pada area dekat pusat pembangkitan dan area basin Laut Sulawesi. Sekitar 25% (5 GW) didisipasi terjadi dekat pusat pembangkitan, peningkatan disipasi energi baroklinik terjadi pada saat gelombang internal berpopagasi menjauhi daerah pusat pembangkitan dengan nilai yang bervariasi antara 1,4 sampai 4,8 GW. Daerah dengan jarak 36 km sampai 54 km terjadi penurunan disipasi energi baroklinik, signal yang kuat dari Kepulaun Sangihe-Talaud berangsur menurun pada saat propagasi dari 10-2sampai 10-3W/m2.

Heavy metal pollution is one of serious problem for tropical mangrove ecosystem. Heavy metals can decrease the quality of a waters. The decreasing in water quality can caused by pollutants such as heavy metals with high concentrations greatly affects the aquatic environment, especially living organisms. The aimed of study is to determine the accumulation level of heavy metals such as Al, Cu, Pb, As, Ni, Cr, Ti, Mn, dan Fe, in root, leaves and stem of E. acoroides. The sampling was carried out in the northern and southern parts of Tunda Island, in March 2015. The method used for seagrass destruction is 6 mL 65% HNO3 and mL H2O2 30%, sediment destruction using Milestone Start D microwave labstation. and using ICP-OES (Inductive Coupled Plasma-Optical Emission Spectrometry) Thermo Scientific iCAP 700 Series. The result show that, the Al, was the dominant heavy metals observed both in sea water and sediment surrounding the observed sea grass areas. Similar result was also observed for seagrass. The dominant sediment grain size absorbing heavy metals is silt-clay because it has more organic matter to control the binding of heavy metals. Heavy metal bioaccumulation is predominant in seagrass leaves and stems due to heavy metal entry into seagrass, substance storage tissue, and seagrass characteristics that are completely submerged in water. Seagrass meadow ecosystem in Tunda Island has been contaminated by several heavy metals.

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.
