“…In the Musi estuary, high chlorophyll a contents were observed in coastal areas. This finding is comparable to the chlorophyll a contents that mostly dominate the Kendal coast, West Java [42]. Chlorophyll a indicates a presence and abundance of phytoplankton that was a food resource for zooplankton.…”

Estuary and river mouth are essential habitats for many commercial estuarine fishes, including the Sciaenidae family. While recently, estuaries have been threatened by anthropogenic marine litter (AML) transported from nearby land and river. An important type of AML is plastic litter since it takes a long degradation time. In the South Sumatra Province, Indonesia, one of the vital estuaries is the Musi estuary. This paper aims to map the spatial distributions of two Sciaenids, including Panna microdon and Otolithoides pama, and Sciaenid’s environmental covariates, including water quality, chlorophyll a, and plastic litters in Musi estuary and model the correlations of Sciaenids with their covariates. The maps were developed using GIS, and the model was validated using AIC methods. The data were collected from 3 river mouths in the west, central, and east of the Musi estuary. The data showed that the populations of both Sciaenids were higher in the east river mouth rather than in the west. Sciaenid populations were positively correlated with high salinity, DO, chlorophyll a, moderate transparency, and low temperature. A high load of AML’s frequency (7.54 items/m2) and weights (36.8 gram/m2) has reduced both Sciaenid populations in the central river mouth of the estuary. In contrast, low AML loads in the east have correlated with high Sciaenid populations. Model selection based on AIC values shows the best model for P.microdon retained an effect of AML weight with AIC values of 22.591 and 28.321 for O. pama. This concludes that the weight of plastic litter in estuary water was the main limiting factor for Sciaenid populations in Musi.

“…Plankton mempunyai manfaat seperti pakan alami bagi makhluk hidup yang ada pada laut (Puspitasari et al, 2019). Plankton yang menjadi sebagai produsen utama dan dapat melakukan fotosintesis adalah fitoplankton dan disebut sebagai klorofil-a (Agung et al, 2018). Melimpahnya fitoplankton pada suatu ekosistem terumbu karang akan menjadi faktor berkumpulnya ikan karang planktivora dan herbivora seperti ikan dari family Caesionidae, Pomacentridae, Scaridae, Acanthuridae, Apoginidae yang termasuk dalam ikan mayor (Ahmad, 2017).…”

Kandungan klorofil-a pada wilayah Suaka Alam Perairan (SAP) Raja Ampat pada tanggal 08 -14 April 2021 cukup bervariasi hasil yang didapatkan dengan konsentrasi sebesar 0,366 mg/m3 sampai 0,511 mg/m3 (Tabel 4.4) dengan nilai kategori 0,3 -1 mg/m3 yang tergolong sedang.…”

The The waters of Raja Ampat have a healthy coral reef ecosystem and a wide variety of species so it has a high abundance of coral reef fish. One of the indicators of fertility level in water is chlorophyll-a and its high and low are influenced by sea surface temperature. The purpose of this study was to determine the relationship between chlorophyll-a content and sea surface temperature using satellite imagery data on the community structure of reef fish in the waters of SAP Raja Ampat. The coral reef fish data collection method used UVC (Underwater Visual Census) while the chlorophyll-a content and sea surface temperature used spatial analysis. The results showed that the reef fish diversity index value was 4,1 - 4,6 in the high category, uniformity 0,88-0,96 in the high category, dominance 0,014 - 0,026 in the low category, for abundance 244.340 ind/ha – 403.520 ind/ha and biomass 131,45 kg/ha - 204 kg/ha. The chlorophyll-a content obtained was 0,366 mg/m3 – 0,511 mg/m3 and the sea surface temperature obtained was 30,717°C – 31,899°C. The results of the relationship of reef fish community structure with chlorophyll-a content and sea surface temperature do not have a significant correlation.

Penelitian ini bertujuan untuk mengetahui distribusi spasial dan temporal klorofil-a di Perairan Teluk Semarang dengan citra Sentinel-3 OLCI. Citra Sentinel-3 OLCI memiliki resolusi sebesar 300 m x 300 m, dengan berdasarkan kepada resolusi spasial yang dihasilkan oleh citra Sentinel-3 OLCI untuk meneliti secara lebih lanjut terkait distribusi spasial dari klorofil-a di Perairan Teluk Semarang dengan resolusi spasial yang cukup baik. Penelitian ini menggunakan diperkuat juga dengan data angin, arus, suhu dan salinitas dari Reanalysis Model yang diolah menggunakan program SNAP dengan metode C2RCC. Berdasarkan hasil penelitian didapatkan bahwa distribusi klorofil-a di perairan Teluk Semarang secara spasial menunjukkan konsentrasi tinggi umumnya di pantai dan semakin ke tengah semakin berkurang. Distribusi klorofil-a di Teluk Semarang secara temporal menunjukkan nilai tertinggi pada Musim Barat dengan puncak pada bulan Januari dan kadar terendah terjadi pada musim timur bulan Juni. Puncak tertinggi kadar klorofil-a pada bulan Januari berada di pesisir Perairan Demak. Faktor yang paling berpengaruh terhadap kadar klorofil-a di Perairan Teluk Semarang adalah run off sungai dan parameter angin. This aim of this research is to determine the spatial and temporal distribution of chlorophyll-a in Semarang Bay using Sentinel-3 OLCI imagery. Sentinel-3 OLCI imagery has a resolution of 300 m x 300 m, based on the spatial resolution generated by Sentinel-3 OLCI imagery to further examine the spatial distribution of chlorophyll-a in Semarang Bay with better spatial resolution. This research also uses wind, current, temperature and salinity data from the Reanalysis Model which is processed using the SNAP program with C2RCC method. Based on the research results, it was found that the distribution of chlorophyll-a spatially and temporally in the Semarang Bay showed a varied pattern. Temporally, the highest chlorophyll-a concentration occurred in January and the lowest was in June..Spatially, chlorophyll-a on the coast of Semarang and Demak is higher than that on the coast of Kendal in the west season, but entering the east season the highest chlorophyll-a is on the Kendal coast than on the coast of Semarang and Demak. Chlorophyll-a distribution in Semarang Bay mostly influenced by river run off and wind.
