Teluk Lampung merupakan jalur perairan penting di Sumatera Selatan yang dipengaruhi oleh aktivitas antropogenik dan karakteristik oseanografis. Penelitian ini mengestimasi produktivitas primer (PP) secara spasial temporal tiga bagian teluk: hulu, tengah, muara, menggunakan data suhu permukaan laut (SPL), klorofil-a, radiasi fotosintesis aktif (PAR) dari penginderaan jauh pengukuran lapangan. Pemodelan PP dilakukan dengan Vertically Generalized Production Model (VGPM) divalidasi metode Root...
Coastal morphology and dynamics influence the sediment transport process from land to coast sea. A study of distribution types was carried out on beach foreshore Carita Beach, Pandeglang Banten, provide an overview deposition processes based grain size distribution. Sediment samples were collected: nine six beach. The analysed using fractionation method with sieving pipetting, organic material content Loss Ignition (LOI) method. Aggregations statistics sediments Gradistat program. water (%)...
ABSTRAKKondisi lingkungan perairan dapat menentukan bentuk pertumbuhan terumbu karang. Penelitian ini dilakukan untuk mengetahui karang pada kondisi yang berbeda di sekitar Teluk Lampung. Pengamatan dengan menggunakan transek kuadrat ukuran (1x1) m2 dan pengolahan data software CPCE (Coral Point Count with Excel Extension). bulan Juli 2013. Hasil pengamatan menunjukan bahwa dominan Lampung adalah bercabang dari genus Acropora (ACB), foliose (CF) massive (CM). Tipe brancing ditemukan daerah...
This area, which is located near the Banten Bay, quite active with anthropogenic activities such as industry, fisheries, settlements, and shipyards that have potential to pollute environment heavy metals. study aims determine chemical environmental conditions of waters concentration metals in sediments Bay. Sediment samples were taken at five stations consisting river bay sections April, May, July, August, September 2019. Heavy metal content was analyzed according APHA 2012 using...
Microalgae harvesting is an important part in microalgae cultivation system. Techniques for marine which are commonly used centrifugation, filtration and flocculation. These techniques still have some disadvantages, such as not environment friendly, high usage of energy cost. Bio-flocculation technique using a flocculant agent can be alternative way to solve these problems. In this research, mixing Tetraselmis suecica (flocculant) with Chlorella sp. Nannochloropsis (non-flocculant) ratios...

Biodiversitas 19: 780-785. Fallen contain that play a role in their decomposition coastal conditions. This research was conducted from September 2016 to February 2017 Pasar Banggi, Rembang, Central Java, with purpose investigating impact leaf various species on exposed litter bags results...
Indonesia has a large cassava diversity, but the tolerant cultivars on drought areas have not been well recorded. Candidate mapping can begin with morphological and physiological characterization. This study aimed to map cassava’s genetic determining key phenotype distinguish genotypes, adaptation, high-yield candidates under environmental stress. A total of 29 genotypes were clustered into 5 groups. specific group for genotype from same site was found. The differences relations among very...
To investigate a suitable biological remediation approaches for anticipating oil spills in Cilacap sandy beach (Indonesia), some alternative strategies using biostimulation and combination of biostimulation-bioaugmentation have been evaluated inter tidal near shore Cilacap, Indonesia. The purpose the study was to compare efficacy slow release fertilizer (SRF) only, biostimulation-single strain bioaugmentation, biostimulation-consortium enhance degradation. experiment conducted sediment...
Jakarta Bay is a crowded area with many activities so that gathering place for pollutants from the land transported through 13 rivers flow in Jakarta. The purpose of this research to explain process and sources heavy metal compare distribution profile water sediment Transitional Season I II Bay. was conducted September 2014. Analysis use procedure (APHA 2012). results showed hydro-oceanographic condition current velocity range 0.002-0.028 m/s wards west southwest, wind speed 4-17 knot...
Phytoplankton in the ocean has an important role forming base of food chain, responsible primary production. Its abundance and number phytoplankton species will indirectly affect level water’s fertility. This study aimed to determine presence as bio-indicators water quality terms abundance, diversity index, uniformity saprobic coefficient coastal waters South Sumatera. The was conducted on May 2013 - February 2014, at ten stations during high low tides. samples were taken vertically using...
Mangroves are a coastal habitat which contributes to the presence of biota through litter they produce.The objective present study was determine physicochemical factors that influenced dynamics Rhizophora mucronata and stylosa mangrove on Banggi Coast, Rembang, Central Java.The research used 1×1 m method between September 2016 August 2017.The results revealed influencing were sediment's organic matter salinity substrate condition.Organic content is high relationship factor influences productivity.
Fish is one of the protein sources for humans which its existence susceptible to contamination, heavy metal. The lack information regarding content metal in edible fish South Sumatera makes this study important be done. This was aimed analyze concentration two species fishes at Musi River Estuary site. conducted estuary section from September November 2014. metals Cu and Pb water organs were analyzed using AAS with a type SpektrA A-20 Variant Plus mixture Air-Acetylene flame. result showed...
<p>Phytoplankton have important as food-chain major component and primary production of marine environment. However, high abundance phytoplankton could give harmful effects toward water ecosystem. Moreover, they produce toxic substances that will be accumulated within their consumer. This accumulation dangerous for human or animals.This research were aimed to determine calculatespecies algae in Banyuasin coastal waters. The study was conducted on April, June, August, October December...
Mangrove forests are known to provide important ecosystem goods and services such as nursery areas for several aquatic species, a variety of food animal groups, including gastropods. This research was conducted from September 2016 - August 2017. The aim the determine spatial temporal pattern distribution C. djadjariensis based on mangrove zone, environmental characteristics, organic materials. gastropod samples were taken by using square transect sized 25 cm x cm. analyses done 10 m m....
