“…While the values of dissolved oxygen, salinity, nitrite, nitrate, and phosphate have values that are still in the optimal category for shrimp growth and microalgae development. The results of measuring these water quality parameters are not much different from the results of measurements carried out by [26], [28], and [29].…”

“…This is following the opinion of [25] which states that the high abundance of microalgae in ponds is influenced by the availability of nutrients in the form of N and P which are continuously available during cultivation activities. Meanwhile, the abundance value of microalgae is still relatively low when compared to the results of a study conducted by [26] which showed data on an abundance value of 40,248,500 -41,837,500 cells/l.…”

Microalgae are organisms that have many variations of species that are very suitable to be developed in all Indonesian waters for use as food, medicine, and biofuels. The method used in this research is a survey method, which is a descriptive study to describe/describe the nature of a phenomenon/condition that existed at the actual time and examine the causes of certain symptoms. The stages of this research include determining the location of the research, data collection techniques, and data analysis of the results of the studies that have been carried out. The data analysis in question was in the form of statistical analysis to compare the proximate content in the form of lipids, starch, and sucrose from microalgae from each sampling location. Correlation tests were also carried out between water nutrient variables, the dominance of microalgae species, and the proximate content of microalgae when sampling was carried out. The results showed that the microalgae species that grew and dominated the media included Skeletonema, Chaetoceros, Diatomae, and Chlorella.

Phytoplankton is microscopic organisms that has a role primary producer and bioindicator of a waters. This study aims to analyze the differences in the phytoplankton community in ponds near and far from settlements as well as to find the condition of the waters. Stations by purposive sampling at 2 stations. The research was conducted in February 2021 in Tanggulrejo Village, Manyar District, Gresik Regency. Phytoplankton samples were analyzed using diversity index (H'), uniformity index (E), dominance index (C), and important value index (INP). The water quality parameters measured were temperature, air brightness, TDS, salinity, DO, dissolved CO2, pH, and nitrate. Statistical test analysis is t test and PCA. The results highest phytoplankton community structure in ponds near settlements, namely, Bacillariophyceae and there were 17 genera, while those far from settlements highest was Cyanophyceae and there were 11 genera. The diversity index value (H') of ponds near medium to settlements is 2.48 while ponds far from settlements is 1.8 which describes the category of phytoplankton community. The Uniformity Index (E) value ponds near settlements is 0, 242, while ponds far from settlements is 0,242 which describes the uneven distribution of phytoplankton. The value of the Dominance Index (C) which is close to the settlement is 0.274, while pond far from the settlement is 0.476, which indicates there is no dominance of a particular genus. The results of water quality parameters indicate that the condition of the shrimp pond waters is polluted because it exceeds the SNI threshold for aquaculture.Keywords: Community Structure, Phytoplankton, Shrimp PondABSTRAKFitoplankton merupakan salah satu oragnisme mikroskopis yang mempunyai peran sebagai produsen primer dan dapat dijadikan sebagai bioindikator suatu perairan, salah satunya tambak. Penelitian ini bertujuan untuk menganalisis perbedaan struktur komunitas fitoplankton pada tambak yang dekat dan jauh dengan pemukiman sekaligus mengevaluasi kondisi perairannya. Penentuan stasiun secara purposive sampling yaitu pengambilan sampel secara random di 2 stasiun, masing-masing stasiun tiga titik. Penelitian dilakukan pada Februari 2021 di Desa Tanggulrejo Kecematan Manyar, Kabupaten Gresik. Sampel fitoplankton dianalisis menggunakan indeks keanekargaman (H’), indeks keseragaman (E), indeks dominasi (C), dan indeks nilai penting (INP). Parameter kualitas air yang diukur yaitu suhu, kecerahan air, TDS, salinitas, DO, CO2 terlarut, pH, dan nitrat. Analisis uji statistik yang digunakan adalah uji t dan PCA. Hasil penelitian menujukkan struktur komunitas fitoplankton tertinggi pada tambak yang dekat pemukiman yaitu, Bacillariophyceae dan ada 17 genus, sedangkan yang jauh dari pemukiman yang tertinggi adalah Cyanophyceae dan ada 11 genus. Nilai Indeks keanekaragaman (H’) tambak dekat dengan pemukiman adalah 2,48, sedangkan tambak jauh dari pemukiman adalah 1,8 yang menggambarkan komunitas fitoplankton kategori sedang. Nilai Indeks Keseragaman (E) tambak dekat pemukiman adalah 0, 242, sedangkan tambak jauh dari pemukiman adalah 0,242 yang menggambarkan tidak merata distribusi fitoplankton. Nilai Indeks Dominasi (C) yang dekat dengan pemukiman adalah 0,274, sedangkan tambak jauh dari pemukiman adalah 0,476, yang menggambarkan tidak ada dominasi genus tertentu. Hasil pengukuran parameter kualitas air menunjukkan kondisi perairan tambak udang yang tercemar karena melebihi ambang batas SNI budidaya.Kata kunci : Struktur Komunitas, Fitoplankton, Tambak Udang

“…This finding was contrary to the results of a study by Yuni and Mustaqim (2020), which showed that the species of the highest abundance in intensive shrimp ponds was Chyanophyta (26 Ind/L) and the least one was Chrysophyta (19 Ind/L). Furthermore, the study by Samadan et al (2020) analyzing the phytoplankton abundance in intensive shrimp ponds found that the highest abundance was Bacillariophyta or Diatom with 6 species.…”

“…Based on its habitat, Halosphaera viridis is very likely to breed well in the vannamei shrimp ponds. Samadan et al (2020) reported that phytoplankton species found in intensive vannamei shrimp aquaculture ponds were 4 genera of Chlorophyta, namely Chlamydomonas, Tetraselmis, Chlorella and Oocytis.…”

Abstract. Palupi M, Fitriadi R, Wijaya R, Raharjo P, Nurwahyuni R. 2021. Diversity of phytoplankton in the whiteleg (Litopenaeus vannamei) shrimp ponds in the south coastal area of ??Pangandaran, Indonesia. Biodiversitas 23: 118-124. Intensive shrimp farming in ponds is characterized by high stocking densities, complete feeding in quality and quantity, and good environmental control to produce the maximum quantity of shrimp in a fixed area. Phytoplankton is a bioindicator affecting the productivity of whiteleg shrimp in ponds. Currently, intensive shrimp farming activity is carried out on the south coast of Java, which utilizes sandy soil with a biofloc system, but the production has not been optimal. The objective of this study was to analyze the diversity and abundance of phytoplankton and water quality in the traditional and intensive whiteleg shrimp ponds in Pangandaran, West Java, to support sustainable pond management. The objective of the study was achieved by calculating the abundance, diversity index, evenness index and dominance index of planktons in intensive and traditional ponds. The study results showed that Chrysophyta division had the highest abundance and species number in both intensive and traditional ponds. The most abundant phytoplankton found in the intensive ponds was Halosphaera viridis (3143.88 ind/m3), and that in the traditional ponds was Rhizosolenia stolterfothi (1414.746 ind/m3). The phytoplankton diversity index (H') in the intensive ponds was 1.95 and that in the traditional ponds was 2.17. The dominance index value in the intensive ponds was 0.18 and in the traditional ponds 0.15. The abundance of phytoplankton is a limitation of the production success of whiteleg shrimp farming.
