Abstract

In this study, the concentrations of three kinds of heavy metals, namely Pb, Zn, and Cu from 3 species of mangrove that grow in Muara Angke were measured and analyzed. Our result showed that substrate of mangrove ecosystem in Muara Angke was dominated by clay (30.5% - 62.4%), silt (21.7% -35.6%), and sand (2% -39.5%). The heavy metals accumulation in roots is higher than in sediment, water and leaves with concentration of Zn as the highest. Bioconcentration Factor (BCF; content ratio of heavy metal concentrations in roots or leaves and sediment) and Translocation Factor (TF; ratio of heavy metal concentrations in leaves and roots) of non-essential heavy metals (Pb) is higher in leaves than in roots, but for essential heavy metals (Zn and Cu), the BCF and TF was higher in roots than in leaves. TF values for heavy metals Pb, Cu, and Zn were 0.98-2.59, 0.17-0.51, and 0.52-0.86, respectively. The values of root BCF of those three heavy metals were 0.71-3.17, 0.27-0.74, and 0.95-1.53, while the values of leaf BCF were 1.84-3.45, 0.07-0.34, and 0.72-1.19, respectively. Furthermore, by calculating the phytoremediation (FTD), i.e. the difference between BCF and TF, it is obtained that Sonneratia caseolaris and Avicennia marina can be used in phytoremidiation, with leaves and roots FTD of 1.93 and 2.09, respectively for Sonneratia caseolaris and 1.93 and 1.98 for Avicennia marina.Keywords: heavy metals, mangroves, phytoremidiation, Muara Angke, bioconcentration factor, translocation factor

Abstract

Mangrove mampu mengakumulasi dan mempunyai toleransi yang tinggi terhadap logam berat sehingga bisa dijadikan tumbuhan untuk tujuan fitoremidiasi (fitostabilisasi). Penelitian ini dilakukan untuk mengetahui potensi fitoremidiasi berdasarkan akumulasi dan translokasi logam berat pada mangrove di daerah pesisir. Sebanyak 10 pohon mangrove (4 spesies) pada 4 stasiun di HLAK dan SMMA diambil untuk dianalisa. Logam berat yang dianalisa dibagi menjadi dua yaitu esensial (Cu dan Zn) dan non esensial (Pb). Hasil analisa fisikokimia perairan dan sedimen menunjukan bahwa mangrove tumbuh pada kondisi normal untuk daerah estuari (pH 7,10-7,46; suhu 28,5-30 0C; salinitas 2-6 ‰; oksigen terlarut 0,71-1,42 mg.L-1 dan kelembaban sedimen 10-30 %). Konsentrasi Zn pada sedimen lebih tinggi dibandingkan Cu dan Pb, namun pada akar dan daun, konsentrasi Pb lebih tinggi dibandingkan Zn dan Cu. Nilai biological accumulation coefficient (BAC=ratio kandungan logam pada daun dengan sedimen), biological transfer coefficient (BTC=ratio kandungan logam pada daun dengan akar) dan bioconcentration factor (BCF=ratio kandungan logam pada akar dengan sedimen) logam non esensial lebih tinggi dibandingkan logam esensial. BAC, BTC, dan BCF Pb adalah 0,84-1,10, 0,84-1,15 dan 0,91-1,09. Nilai BAC, BTC, dan BCF logam Cu dan Zn berturut adalah 0,02-0,13 & 0,12-0,25, 0,17-082 & 0,56-1,11 dan 0,09-0,17 & 0,13-0,25. Untuk tujuan fitoremidiasi, mangrove bisa diterapkan di daerah pesisir sebagai fitostabilisasi. Hasil perhitungan FTD menunjukan spesies Sonneratia caseolaris 3 bisa dijadikan sebagai kriteria mangrove untuk fitoremediasi. Kata kunci: mangrove, fitoremidiasi, logam berat, pesisir Abstract Mangroves are able to accumulate and have a high tolerance to heavy metals so that those trees can be used as phytoremidiation purpose (phytostabilization). This study was conducted to determine metal phytoremidiation potential of mangroves based on accumulation and translocation of heavy metals in coastal areas. A total of 10 of mangrove trees (4 species) at 4 stasions in HLAK and SMMA were taken and analyzed. Heavy metal divided into two such as essential (Cu and Zn) and non essential (Pb). Based on phycochemical analysis both of water and sediment,our result showed that mangroves grow on normal condition for estuarine ecosystem (pH 7.10-7.46; temperature 28.5-30 0C; salinity 2-6‰; dissolved oxygen 0.71-1.42 mg.L-1 dan humidity of sediment 10-30%). Concentration of Zn  in sediment was higher than Cu and Pb, but in roots and leaves Pb was higher than Zn and Cu. Biological accumulation coefficient (BAC=ratio of leaf metal to sediment metal concentration), biological transfer coefficient (BTC= ratio of leaf metal to root concentration) and bioconcentration factor (BCF= ratio of root metal to sediment metal concentration) for non essential is higher than essential. BAC, BTC and  BCF Pb metal were 0.84-1.10, 0.84-1.15 and 0.91-1.09, respectively. While value of  BAC, BTC  and BCF  for Cu and Zn were adalah 0.02-0.13 & 0.12-0.25, 0.17-082 & 0.56-1.11 and 0.09-0.17 & 0.13-0.25, respectively. For phytoremidiation purposes, mangroves are perhaps best employed as phytostabilisers. Result of calculating FTD showed that species of Sonneratia caseolaris 3 can be used  as mangrove criterion for those purpose. Keywords: mangrove, phytoremidiation, heavy metals, coastal

Abstract

A vertical distribution of nutrient shows an interaction of physical processes, source, and uptake along the water column. These interactions can occur along the water column with different processes in each layer. Water samples from 17 stations were collected for nitrate, phosphate, and silicates concentration analyses during the transitional season in the Weda Bay. During the transitional season, the Weda Bay was characterized by low salinity (33.55-34.10), relatively warm temperature (30.87°C), and the relatively low nutrient concentrations (nitrate=0.03-4.87 µg at/l, phosphate=0.011-0.852 µg at/l, and silicate=0.04-1.21 µg at/l). The present of Western North Pacific Ocean (WNPO) watermass and the influence of Southern Subtropical Lower Water (SSLW) producing high salinity (>35) at the depth of 130-300 m were observed along the Weda Bay. Nutrient geochemical processes in this region were shown by nutrient utilization and regeneration across the water columns. Nutrients utilization was relatively high in the surface layer. Meanwhile, nutrients regeneration and remineralization were more dominant in the thermocline and deeper water layers. Analyses of nutrients showed that nitrate was more dominant than other nutrients with N/P ratio was 3.83-37.99 and N/Si ratio was 0.12-10.98. The effectiveness of silicate (0.25 μg at/l) that was used by phytoplankton found at a depth of 200 m when its concentration decreased at N/P ratio (16:08) close to the Redfield ratio. Due to an uptake, remineralization, and regeneration processes in each layer, a nutrient distribution pattern was formed which the nutrient concentrations decreased in mixed layer and increased in the deeper water.Keywords:nutrien, pattern, Weda Bay, transitional season

Abstract

Mangrove plantation projects have been established in the created mangrove wetland in the mouth of the Porong River, East Java, in parallel with the construction of reclamation area for LUSI mud dumping area. This study was aimed to assess the growth of planted mangrove in a created mangrove wetland in relation to the environmental parameters, which are sediment salinity, sediment fraction, pore water salinity, pH/eH, and total organic matter (TOM) in the sediment. Periodical measurement of mangrove growth Avicennia sp. and the environmental parameters were undertaken in the created wetland and in the mud flats of intact mangrove forest nearby the created wetland as the natural reference in July to November 2012. We found that sediments in the created wetland had different characteristics of sediment fractions, sediment salinity and TOM compared to sediments in the mud flats of intact forests. Sand dominated sediments with low TOM and higher water salinity in the created wetland as compared to those in the mud flats affected growth rate of mangroves in study sites. We suggest that TOM and salinity are important factors that contribute to the growth of mangroves in the Porong River. Keywords: Mangrove, salinity, Porong River, total organic matter.

Abstract

Samudera Pasifik berperan penting dalam siklus El-Nino Southern Oscillation (ENSO) dan berpengaruh signifikan pada kegiatan penangkapan tuna di Indonesia, khususnya ikan Cakalang. Penelitian ini bertujuan mengetahui pola pergerakan zona konvergensi di Samudera Pasifik bagian Barat dengan mengamati pergerakan parameter oseanografi seperti suhu, salinitas, klorofil-a, dan produktivitas primer. Data parameter oseanografi tersebut terdiri dari data insitu, data satelit maupun hasil pemodelan. Hasil analisis menunjukan adanya pergerakan zona konvergensi di Barat Pasifik yang dicirikan variabel proksi yaitu isotermal 29°C, isohalin 34,6 psu, konsenrasi klorofil-a sebesar 0,1 mg/m3 dan NPP 300 mgC/m2/day. Pola pergerakan zona konvergensi baik secara horisontal maupun vertikal dipengaruhi oleh ENSO. Pada saat terjadi La-Nina massa air dengan suhu yang hangat bergeser ke arah Barat yang diikuti dengan meningkatnya kesuburan perairan. Pergerakan vertikal massa air hangat terjadi pada kedalaman 25-75 m (suhu) dan 50 m (salinitas). Namun pada saat El-Nino massa air hangat bergerak ke arah Timur Samudera Pasifik. Fluktuasi produksi tangkapan ikan Cakalang di perairan Indonesia Timur mengikuti pola pergerakan zona konvergensi tersebut. Peningkatan jumlah produksi ikan Cakalang di Kota Sorong meningkat seiring dengan keberadaan zona konvergensi di bagian Barat (La-Nina), namun di Propinsi Papua menunjukan pola sebaliknya.

Abstract

Oksigen merupakan gas penting dalam perairan laut dan berperan dalam proses biogeokimia laut. Sumber oksigen berasal dari difusi dari udara melalui proses turbelensi dan hasil fotosintesis. Penelitian ini bertujuan untuk mengkaji distribusi dan pengaruh Indonesian Throughflow (ITF) terhadap konsentrasi oksigen terlarut di Selat Lombok. Sebanyak 11 stasiun (3 di utara; 6 di tengah; 2 di selatan) dianalisis kandungan oksigen terlarutnya dengan menggunakan metode modifikasi winkler. Hasil analisis menunjukan bahwa kandungan oksigen di bagian utara berkisar 2,48-7,15 mg/l, tengah 2,32-6,58 mg/l dan selatan 2,35-6,71 mg/l. Berdasarkan nilai apparent oxygen utilization (-2,70–5,64 mg/l) dan normal atmospheric equilibrium concentration (3,84-7,96 mg/l), mencerminkan kandungan oksigen yang semakin berkurang pada lapisan permukaan. AOU dan NAEC secara implisit berubah terhadap kedalaman dimana konsentrasinya akan semakin tinggi  dengan bertambahnya kedalaman. Hasil pengukuran suhu dan salinitas menunjukan bahwa Selat Lombok mempunyai suhu dan salinitas masing-masing berkisar antara 4,74-30,080C dan 33,48-34,78 psu. Analisis TS-diagram menunjukan terdapat dua massa air yang membawa kandungan oksigen di Selat Lombok yaitu Northern Subtropical Lower Water (NSLW) (salinitas=34,53-34,58 psu, suhu=13,57-15,06 0C; sigma-t (s t)=25,40-25,80)) dan Northern Pacific Intermediate Water  (NPIW) (salinitas=34,48-34,54 psu; suhu=6,30-7,90 0C; sigma-t (s t)=26,70-27,20). NSLW ditemukan pada kedalaman 100-180 (utara), 100-550 m (tengah) dan 190-220 m (selatan), sedangkan NPIW tidak terlihat dengan menggunakan pendekatan oksigen terlarut dan hanya bisa dilihat dengan pendekatan suhu dan salinitas.
