Abstract. One of the regions in Surabaya which has accumulated the largest pollution levels was the region of Wonorejo. Wonorejo is an area that is used as a mangrove conservation. But,Pb and Cu are heavy metals that have been detected in high concentration in this region. Avicennia albahas been known to have the ability to absorb heavy metals so that mangrove can be used us phytoremediation agent. The purposes of this research were to analyze the concentration of heavy metals (Pb and Cu) in sediments, roots and leaves of Avicennia alba; to understand the potential of Avicennia albaas an agent of phytoremediation. The result showed that Cu concentration was higher than Pb concentration in sediment, roots and leaves. The concentrations of Cu were4.13 ppm - 36.95 ppm and Pb between 3.28 ppm - 23.79 ppm. Based on bioconcentration factor (BCF) Avicennia alba was categorize as excluder (BCF1) of both heavy metals, but concentration oftranslocation factor (TF) of Pb was categorized phytoexstraction (TF1) and Cu was categorized phytostabilization (TF1). The result of the BCF and TF showed that Avicennia alba can absorb heavy metals (Pb and Cu) from the environment, however the mobility of the heavy metals in the mangrove will experience different phytoremediation mechanisms (phytostabilization for Cu; phytoexstractionfor Pb).Keywords: Avicennia alba, Phytoremediation, Factor Bioconcentration, Factor Translocation, Heavy Metal (Pb and Cu) Abstrak.

Abstract. Mangrove ecosystem of Lamong River is located in an area with dense human activities such as industrial, heavy traffic, settlements and harbour activities. These activities could triggered the input of heavy metals, especially Pb and Cu. Mangrove ecosystem can be developed as a control of heavy metal pollution and also as a pollutant trap. In this study, the analysis of heavy metals (Pb and Cu) in water, sediment and mangorve’s roots and leaves were measured. The aim of this study was to determine the ability of Avicennia marina’s roots and leaves in absorbing heavy metals (Pb and Cu). Samples were obtained and then analysed by AAS (Atomic Absorbsion Spectrofotometer).The result showed that heavy metal concentrations of Pb were in the range of 0.11 mg/L - 16.87 mg/L and Cu in the range of 0.001 mg/L - 34.84 mg/L.Avicennia marina in the study site was categorized as excluder based on BCF1 and phytoextraction due to TF1. The results of this study indicate that Avicennia marina can be developed into phytoremidiation agents because they was able to absorb and transfer heavy metals from the environment to their plant tissues.Keywords: BCF; TF; Avicennia marina; Heavy metal; Lamong River Abstrak.

Hawksbill turtles were observed nesting along the coast of Baluran, mainly at Batu Hitam Beach. The eggs were relocated to a hatchery on Bama Beach, which is a beach where hawksbill turtles have never been seen laying eggs naturally. Referring to the natal homing/philopatry hypothesis, hatchlings that are released on Bama Beach will likely come back to lay eggs in the future. Meanwhile, Batu Hitam Beach is planned to be developed into a tourist area. To preserve this important nesting area, a nesting habitat suitability assessment is needed that can contribute to effective conservation planning and management. This study used observational data to identify the bio-physical characteristics of the beaches and analyzed them using the habitat suitability index (HSI). The parameters observed were the width and slope of the beach, percentage of sand, intensity of light, coastal vegetation, percentage of buildings, and the distance between the nesting beach and the feeding area. There were no significant differences in bio-physical characteristics between the two beaches. Except for beach width, all other parameters are given the same score. Batu Hitam Beach has a slightly wider and steeper beach than Batu Hitam Beach. Based on the results of an assessment utilizing the habitat suitability index (HSI) for hawksbill nesting sites, the biophysical conditions of Bama Beach and Batu Hitam Beach were assessed as very suitable (>68.86%). Despite Bama Beach's suitability, there have been no reports of hawksbill turtles nesting there. The width of the beach that is too narrow and a lack of coastal vegetation shade are thought to have forced the hawksbill to prefer other locations, such as Batu Hitam Beach. Penyu sisik teramati bertelur di sepanjang pesisir Baluran, terutama di Pantai Batu Hitam. Telur yang ditemukan dipindahkan ke tempat penetasan di Pantai Bama, pantai yang belum pernah tercatat penyu bertelur secara alami. Merujuk pada hipotesis natal homing/philopatry, tukik yang dilepasliarkan di Pantai Bama dimungkinan akan kembali untuk bertelur di kemudian hari. Di sisi lain, Pantai Batu Hitam rencananya akan dikembangkan menjadi kawasan wisata. Untuk melestarikan habitat peneluran ini, diperlukan penilaian kesesuaian habitat bersarang yang dapat berkontribusi pada perencanaan dan pengelolaan konservasi yang efektif. Penelitian ini menggunakan pendekatan observasional untuk mengidentifikasi karakteristik bio-fisik pantai dan menganalisisnya menggunakan indeks kesesuaian habitat (IKH). Parameter yang diamati adalah lebar dan kemiringan pantai, persentase pasir, intensitas cahaya, vegetasi pantai, persentase bangunan, dan jarak antara pantai peneluran dengan area pakan. Tidak terdapat perbedaan kondisi bio-fisik yang signifikan antara kedua pantai tersebut. Seluruh parameter mendapatkan skor yang sama, kecuali lebar pantai. Pantai Batu Hitam memiliki pantai yang sedikit lebih lebar dan lebih curam daripada Pantai Batu Hitam. Berdasarkan hasil penilaian dengan memanfaatkan Indeks Kesesuaian Habitat (IKH) peneluran penyu sisik, kondisi bio-fisik Pantai Bama dan Pantai Batu Hitam dinilai sangat sesuai (>68,86%). Meskipun hasil penilaian kondisi Pantai Bama sesuai menjadi habitat peneluran, belum ada laporan penyu sisik bertelur di sana. Lebar pantai yang terlalu sempit dan kurang meratanya naungan vegetasi pantai diduga menjadi penyebab penyu sisik memilih pantai lain di sekitar Pantai Bama, salah satunya adalah Pantai Batu Hitam.

HighlightsConcentration of lead (Pb) in the surface water and sediment were analyzedThe ecological risks of metal in the ecosystem were assessedPb concentration in the surface water and sediment were observed in the similar range Pb in the study areas has low ecological risk indexConcern on Pb contamination in Prigi Harbor is neededAbstractThis study attempts to measure the spatial distribution of Pb in the seawater and surface sediments and to analyze its potential harmful effect in the surface sediments of the coastal areas of Prigi Bay, Trenggalek. Prigi Bay has been considered as one of the harbors with substantial activities from fisheries, tourism, and domestic events in Indonesia. These activities may discharge heavy metals, e.g., lead (Pb) into the environment and bring hazard to animal and human life. Data for Pb concentrations were collected from two stations near Prigi Harbor (Stations 1 and 2), one station in the Prigi Beach (Station 3) and two stations near the river mouths (Stations 4 and 5). Water quality parameters (temperature, salinity, pH, and DO) were also measured. Stations 1 and 4 displayed a higher concentration of Pb in the seawater than in the surface sediments. On the other hand, Stations 3 and 5 showed a higher concentration of Pb in the surface sediments than in the seawater. Pb concentration in the seawater was 0.22-0.60 mg/kg, and in the surface, sediments were in the range of 0.40-0.57 mg/kg. According to the analysis of contamination factor (CF), the study sites have a low degree of contamination from heavy metal Pb (CF < 1). The result was also supported by the potential toxicity of Pb to the benthic environment around Prigi Bay that was still considered low (E < 40). In spite of the low degree of contamination and low potential toxicity from Pb, concern regarding the heavy metal pollution in the study areas is still needed due to substantial activities that can contribute to the accumulation of heavy metal in a long time.

HighlightHeavy metals (Cu, Zn, Pb, and Cd) in the seawater, sediment, and soft part of marine mussels were analyzedBioaccumulation Factor (BAF), Estimated Daily Intake and Target Hazard Quotient (THQ) were calculatedHeavy metals in the seawater, sediment and marine mussels were found in varying concentrationsHealth risk assessment indexes showed low values which means insignificant health hazardAbstractMarine mussels are known as one of the biological indicators of heavy metals pollution in the aquatic environment and the sources of protein for human consumption. This study aimed to investigate the concentration of heavy metals (Cu, Zn, Pb, and Cd) in the seawater, sediment, and soft parts of the marine mussels (Perna viridis, Meretrix sp., and Anadara granosa), as well as to evaluate its health risk of consumption from Madura Strait, Indonesia. The seawater, sediment, and marine mussels were obtained from four sites and heavy metal concentrations were analyzed using Atomic Absorption Spectroscopy. In the seawater, heavy metals were in the order of Cu, Pb, Cd, and Zn from the highest to the lowest concentration respectively, while they went down in the order of Zn, Cu, Pb, and Cd in the sediment respectively. Excluding the Pb, higher Cu and Zn concentrations were observed in marine mussels than in seawater and sediments (BAF> 1). Furthermore, it was proven that Cu and Zn were considered as essential metals and required for metabolism, while Pb and Cd were non-essential metals which their biological functions were unknown. The Estimated Daily Intake (EDI) of the marine mussels was lower than the oral reference dose (ORD) and low values of target hazard quotient (THQ < 1) had shown that the consumption of mussels containing heavy metals would not cause significant health risks to humans. The health risk assessment indexes showed low values, which meant insignificant health hazard. However, long-term exposure and the impact of consuming mussels containing heavy metals may require additional investigation

Highlight Research This is the first study of microplastics in four beach sediments in the east part of Java Island. Bahak and Pesona Beach are connected to Java Sea (north part), while Tambak Rejo and Balekambang Beach are connected to Indian Ocean (south part). A higher microplastics were observed on the beaches of the north part compared to the south part. Local sources and oceanographic parameters of the beaches influence the presence of microplastics in the study areas. Abstract Microplastic pollution in beach sediments has been studied intensively worldwide, but there are limited studies in the beach areas of the eastern Java Island, Indonesia. This study aimed to identify the distribution of microplastic in four beaches in Indonesia: Bahak, Pesona, Tambakrejo, and Balekambang. The first two beaches are located in the north of Java Island and influenced by the east Java Sea, while the last two are located in the south and influenced by the Indian Ocean. Sediment samples were collected along the strandline inside the 1 í— 1 m transect quadrate in the top 5 cm using a stainless-steel shovel. Microplastic and granulometry analyses were conducted to obtain microplastic and sediment grain size data, respectively. Physical parameters of the beaches, such as wind, wave, and ocean current, were calculated using Copernicus and NASA (PODAAC), respectively. The total abundance of microplastic ranged from 54.7 ± 48.6 to 103.3 ± 4.7 particles kg-1 with the following descending order: Bahak > Pesona > Tambakrejo > Balekambang. Although there was no statistically significant difference in microplastic concentrations among the beaches, the beaches connected to the Java Sea accumulated more microplastics than the ones connected to the Indian Ocean. Fiber and blue were the dominating type and colors of microplastic. The results confirm that the distribution of microplastic is associated with the morphology of the beaches and the local source.
