Abstract

Phytoplankton are primary producers that can be used as seawater condition indicators. Certain phytoplankton can proliferate, causing harmful algal blooms (HABs). The coastal waters of South Sulawesi, Indonesia are under pressure from land-based processes and activities resulting in inputs of organic and inorganic materials. This study analysed phytoplankton diversity and abundance in coastal waters around South Sulawesi. Phytoplankton were sampled and seawater parameters (salinity, temperature, turbidity, pH, nitrate concentration) measured in-situ at six stations around seven major river estuaries in three seaways (Makassar Strait, Flores Sea, Gulf of Bone). Phytoplankton taxonomic composition, abundance and indices of diversity (H’), evenness (E), and dominance (D) were analysed. Phytoplankton from 31 species and three classes (Bacillariophyceae, Cyanophyceae, Dinophyceae) were identified. Phytoplankton abundance and community structure differed significantly between sites and seaways but were not significantly correlated with water quality parameters although Dinophyceae abundance correlated significantly with observed pollution levels. Phytoplankton abundance was strongly influenced by the Dinophyceae, especially Ceratium furca, a potential HAB species; Cyanophyceae had the strongest influence on species richness but least on community structure. C. furca abundance was strongly correlated negatively with species richness, H’ and E, and positively with D, indicating negative impacts of this species on phytoplankton communities.

Abstract

Water quality parameters can be indicators of pollution driving riverine, estuarine and coastal resource degradation. This study evaluated water quality in the downstream, estuarine and surrounding coastal waters of 8 major rivers around the western, southern and eastern coasts of South Sulawesi Province, Indonesia. Data on physical and chemical parameters (salinity, temperature, total dissolved solids (TDS), conductivity, turbidity, pH, dissolved oxygen (DO), nitrate and ammonium) were collected during January 2020. These data were interpolated and mapped using the Kriging tool in ArcGIS 9.3 and analysed using the STORET scale and principle component analysis (PCA).  STORET values indicate moderate to heavy pollution, with the most severe pollution in Makassar City. Dominant defining parameters based on the PCA were nitrate, ammonium and DO at the Malili and Makassar sites,  pH, temperature, TDS and salinity at the Palopo, Bulukumba and Pangkep sites, conductivity at the Takalar site and turbidity at the Pinrang site.

Abstract

Budidaya tambak merupakan andalan perikanan di Kabupaten Sidoarjo Provinsi Jawa Timur, namun terdapat berbagai kegiatan yang berpotensi menghasilkan bahan pencemar berupa logam berat di kawasan pesisir yang menjadi sumber air bagi budidaya tambak. Penelitian ini bertujuan untuk menentukan konsentrasi dan status mutu logam berat dalam air sehubungan dengan potensi pencemaran dalam air yang mungkin terjadi dalam kaitannya dengan pemanfaatan untuk budidaya tambak. Penelitian dilaksanakan di kawasan pesisir Kecamatan Jabon Kabupaten Sidoarjo dengan mengambil contoh air pada 12 stasiun pengambilan contoh dan selanjutnya dianalisis di laboratorium untuk logam berat As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Pb, dan Zn. Data dari hasil analisis logam berat dianalisis secara deskriptif dan selanjutnya dengan metode Storage and Retrieval (Storet) digunakan untuk menentukan status mutu air dari logam berat untuk biota laut. Hasil penelitian yang dilakukan pada tahun 2015 ini menunjukkan bahwa kisaran konsentrasi Co, Hg, Mn, Mo, Pb, dan Zn berturut-turut < 0,001-0,072; < 0,001-0,045; 0,02-0,18; < 0,001-0,011; 0,309-0,835; dan 0,01-0,04 mg/L. Hasil penentuan status mutu air menunjukkan bahwa air di kawasan pesisir Kecamatan Jabon tergolong tercemar berat dari logam berat Hg dan Pb untuk biota laut. Disarankan agar kegiatan yang dapat menjadi sumber pencemar logam berat terutama Hg dan Pb di kawasan pesisir Kecamatan Jabon agar dikurangi dan atau mengaplikasikan Instalasi Pengolahan Air Limbah dan merehabilitasi hutan mangrove untuk menjadi bioakumulator logam berat, serta melakukan pengelolaan berkelanjutan yang meliputi pemantauan, pembinaan, dan penegakan hukum sehingga dapat menjadi sumber air untuk budidaya tambak yang produktif dan berkelanjutan.Brackishwater aquaculture is one of the major aquaculture activities in Sidoarjo District, East Java Province. Unfortunately, its sustainability is currently threatened by the increased level of heavy metal pollutants in the coastal waters used as the major water source for the fish farming activity. The objective of this study was to determine the concentrations and distribution of heavy metal elements in the coastal water and devised potential mitigation plans in relation to the sustainability of existing brackishwater in the area. Water samples were collected from 12 sampling stations on the coastal waters of Jabon Subdistrict, Sidoarjo District. Laboratory analyses were performed to identify and measure the level of the heavy metal elements including As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Pb, and Zn. The results of the analysis were descriptively discussed. The Storage and Retrieval (Storet) method was used to determine the quality status of the coastal water based on heavy metals standard limits for marine biota. The results of this 2015 research showed that the concentrations of Co, Hg, Mn, Mo, Pb, and Zn were < 0.001-0.072; < 0.001-0.045; 0.02-0.18; < 0.001-0.011; 0.309-0.835; and 0.01-0.04mg/L, respectively. These heavy metal levels showed that water quality in the coastal area of Jabon Subdistrict was heavily polluted, particularly by Hg and Pb for marine biota. This research recommended that activities in the coastal area suspected to be the sources of heavy metals contaminants, especially Hg and Pb, have to be controlled or reduced. The application of wastewater treatment plants, rehabilitating mangrove forests as heavy metal bio accumulators as well as the implementation of sustainable water management procedures through monitoring, guidance, and law enforcement are highly recommended to ensure the long term sustainability of brackishwater aquaculture activities in the study area.

Abstract

This study aims to examine its sustainability status. This study used survey techniques and interviews with seaweed cultivators to collect data. Sustainability data on seaweed cultivation include social, economic, and ecological aspects. The Rapseaweed approach (Rapid Appraisal for Seaweed) has been modified from Rapfish (Rapid Appraisal for Fisheries) to evaluate the sustainability status of seaweed in a multidisciplinary manner. Analysis of the sustainability of K. alvarezii seaweed cultivation using the MDS method. The Rapseaweed analysis reveals that the ecological sustainability index value is 57.76, and the availability of seeds is the most sensitive attribute, with a change in root mean square RMS value of 4.59. Seaweed marketing is the most sensitive attribute, with a change in root mean square RMS value of 12.96, and the economic dimension index value is 65.62. The cultivator's habits have the highest index value of 69.75% for the social dimension, with a root mean square RMS change value of 10.47. All dimensions are considered to be "sufficiently sustainable" by these index values. In the three dimensions, each RMS value indicates that there are sensitive attributes whose existence is suppressed or paid attention to. To obtain a strategic direction for the management of seaweed cultivation in Baubau City based on the RMS value, which has been ranked from highest to lowest, a seaweed management strategy for related stakeholders, namely the local government, the industrial sector, and the cultivating community, namely; strengthening coastal communities' capacity to maximize seaweed cultivation activities, ensuring market availability and price stability, and increasing production at seaweed cultivation centre locations

Abstract

ABSTRACTCultivation of green mussels (Perna viridis) using multilevel plastic baskets has been carried out in the waters of Salemo Island, Pangkep Regency, Indonesia. The purpose of this study was to determine the oceanographic parameters that affect mussel cultivation at different water depths. The research treatment was placement on the surface and bottom of the waters (five meters deep) with different stocking densities. Green mussel cultivation is carried out for 4 months, namely May, June, July and August. Measurement of oceanographic parameters was carried out every month during green mussel cultivation, in situ, namely temperature, turbidity, salinity, pH, DO and those analyzed in the laboratory, namely TSS, TOM, Nitrate, Phosphate and the composition and abundance of plankton. Growth measurements of green mussels were also carried out, namely absolute weight and survival (SR). The results showed that the condition of oceanographic parameters differed between the surface and bottom waters, especially the parameters of TSS, turbidity, TOM, nutrients and plankton abundance. This situation is related to the absolute growth value and SR of mussels at different stocking densities and depths.Keywords: Oceanographic, green mussels, multilevel baskets, absolute growth, Salemo
