“…Wastes from these activities is removed into river and have impact to periphyton. The blooming diatoms have been founded in many research like [2], [3], [4], [5], [6], [7]. Ekwu and Sikoki [2] said the diatoms present indicates there is high silica in the river.…”

Abstract-Sinamar River is one of the rivers in Lima Puluh KotaDistrict, that have important functional. This river is used as irrigation, bathing and washing, and husbandaries. There are many human activities as long as this river such as residents, industries, tradisional markets, and agricultural. The objective of this studi is to know the level of Sinamar River pollution based on microalgae periphytons communities. The samples was taken in 8 stations. The result are microalgae periphytones in Batang Sinamar founded 24 spesies, Cyanophyta (3 spesies), Chloropyhta (7 spesies), Chrysophyta (12 spesies), Euglenophyta (2 Spesies). Diversity .indeks is about 2,51 -2,75 and saprophyt index is about 0,9 -1,3. This is indicated Batang Sinamar contaminated lightly. Based on water quality, Batang Sinamar has DO 6,33

“…Microalgae were collected by sieving 100 L of seawater using plankton nets with specification Wildco 45 um Nitex® mesh (Effendi et al 2016). These samples were preserved using 1 mL of Lugol and kept in a cool box while transferred to Laboratorium of Hydrobiology in Faculty of Fisheries and Marine Sciences for identification and analysis using a binocular microscope and identification handbook (Perry 2003;Vuuren et al 2006).…”

Abstract. Zakiyah U, Mulyanto, Suwanti LT, Koerniawan MD, Suyono EA, Budiman A, Siregar UJ. 2020. Diversity and distribution of microalgae in coastal areas of East Java, Indonesia. Biodiversitas 21: 1149-1159. Indonesia is well known as one of hotspot for biodiversity, including marine resources. However, Indonesia biodiversity has declined rapidly due to the changes in the aquatic environmental quality as the consequence of human activities. Biodiversity loss has been well studied in larger organisms, however, less is known for microorganisms, such as microalgae. Microalgae have received much attention recently due to its potential as renewable energy sources. This study aimed at describing biodiversity and distribution of microalgae in coastal areas of East Java and Madura, Indonesia. Six sites, i.e. Trenggalek and Sendangbiru representing south coast, Banyuwangi and Situbondo representing north coast of East Java, Pasongsongan and Pamekasan representing Madura north and south coast, respectively were sampled, which representing different background of anthropogenic development in these areas. Results showed that seawater condition in all sites is still good, with average pH 8.0 despite intense human activities, such as ecotourism, fishing and boat harbor, as well as residential area that has the potential to produce a lot of waste. Totally, there were 35 genera from all locations with varying abundance in each location and diversity index ranging from 1.105-3.312. Although most genera belonged to Bacyllariophyta, domination indices showed that there was not any single specific domination in all locations. Morisita indices showed that most distribution gave positive values indicating clumped dispersion of microalgae in all locations. Higher Shannon-Weaver indices characterized the south coast of East Java and Madura compared to the north coast of East Java area, which corresponded with lower dominancy indices.

“…Intensitas cahaya matahari pada pagi, siang dan sore hari di setiap stasiun diukur dengan menggunakan light meter. Pengambilan sampel mikroalga (fitoplankton) dilakukan melalui penyaringan air laut sebanyak 50 L menggunakan plankton net Wildco 12" 100 µm Nitex® mesh, P tali =2 M (Effendi et al, 2016). Air yang tersaring di dalam plankton net kemudian ditampung ke dalam botol sampel ukuran 250 ml disimpan dalam kondisi dingin dengan suhu 4°C menggunakan cool box, dibawa dan disimpan dalam cold storage selama 7 hari, selanjutnya disaring dengan menggunakan kertas Whatman paper grade 42: 2,5 µm (slow filter paper), kemudian disimpan selama 12 jam ke dalam tabung reaksi yang berisi aceton pigmen extraction sebanyak 10 mL dan dalam refrigerator (Wasmund et al, 2006).…”

ABSTRAKCahaya matahari merupakan salah satu faktor lingkungan terpenting baik secara langsung maupun tidak langsung bagi organisme fotosintetik perairan dalam menyediakan energi untuk diubah menjadi energi kimia dengan bantuan klorofil. Penelitian ini bertujuan untuk mengkaji hubungan antara ketersediaan cahaya matahari dan konsentrasi pigmen fotosintetik di Perairan Selat Bali. Penelitian dilaksanakan pada pagi, siang dan sore hari pada lima stasiun penelitian di Perairan Selat Bali. Analisis korelasi kanonik digunakan untuk mengetahui hubungan antara ketersediaan cahaya matahari dan pembentukan pigmen fotosintetik. Hasil penelitian menunjukkan bahwa intensitas cahaya matahari (Y2) lebih berpengaruh terhadap pembentukan pigmen klorofil-b (Y1) dengan korelasi kanonik sebesar 0,4512 bilamana dibandingkan dengan pembentukan pigmen klorofil-a (Y1) dengan nilai korelasi sebesar 0,3982. Semakin tinggi pembentukan pigmen klorofil-b (Y1) dapat meningkatkan pembentukan pigmen karotenoid (Y1) secara signifikan dengan nilai korelasi kanonik sebesar 0,7419. Kesimpulan dari hasil ini, bahwa pigmen klorofil-b dan pigmen karotenoid akan terbentuk secara optimum pada intensitas cahaya rendah. ABSTRACTSunlight is one of the most important environmental factors both directly and indirectly for photosynthetic organisms in providing energy to be converted into chemical energy with the help of chlorophyll. This study aims to examine the relationship between the availability of sunlight and the concentration of photosynthetic pigments in Bali Strait waters. The study was conducted in the morning, midday and afternoon at five research stations in the Bali Strait waters. Canonical correlation analysis was used to determine the relationship between sunlight availability and photosynthetic pigment formation. The results showed that the intensity of sunlight (Y2) had more influence on the formation of chlorophyll-b (Y1) pigments with canonical correlation of 0.4512 when compared with the formation of chlorophyll-a (Y1) pigment with a correlation value of 0.3982. The higher formation of chlorophyll-b (Y1) pigments can significantly increase the formation of carotenoid pigments (Y1) with canonical correlation values of 0.7419. From these results it can be concluded that chlorophyll-b pigments and carotenoid pigments will be formed optimally at low light intensities.
