Abstract

TEST ANTIFOULING ACTIVITY OF Avicennia marina (API-API) FRACTION AS A NATURAL ANTIFOULING ON MACROFOULING AT SUNGSANG WHARF Ulil Sarifatul Aliyah NIM.08041281722022 SUMMARY Biofouling organisms generally cause problems that are detrimental to shipping transportation, such as damage to ship hulls, destroying structured substrates, blocking sewage lines. This problem can be overcome by using antifouling paint which usually contains trybuyultin (TBT) compound which prevents the attachment of biofouling. The compound has an adverse effect on non-target organisms and is proven, due to its toxic properties and in the marine environment. So the development of antifouling paint using natural compounds is needed. Alkaloid compounds, tannins, terpenoids and steroids are some natural substances known to have antifouling effects. Avicennia marina is a plant that contains alkaloids, saponins, tannins, phenolics, flavonoids, triterpenoids and glycosides. This study aims to determine the active compounds in Avicenna marina as an environmentally friendly alternative to antifouling. This research was conducted from February to June 2021. The method used in this study was experimental. Based on the research that has been done, it can be seen that the leaf fraction of Avicennia marina has secondary metabolites. The methanol fraction contains steroids, flavonoids, and saponins. The n-hexane fraction contains tannins, triterpenoids, alkaloids, flavonoids, saponins, and the ethyl acetate fraction contains triterpenoids, flavonoids, and saponins. Based on the results of One Way ANOVA test, the effect of concentration and fraction of methanol, n-hexane, and ethyl acetate fraction on the area of attachment of macrofouling has a significant effect. the methanol fraction and the ethyl acetate fraction have a percentage of the area of attachment above 50%, which means that the value is in the high category. The percentage of area attached to the n-hexane fraction has a value of 46.3%, which means it has a medium category value. The macrofouling attached to the test plate were sea slugs (Littoraria angulifera) and barnacles (Semibalanus balanoides). Keywords : Antifouling, Macrofouling, Avicennia marina, Fractionation UJI AKTIVITAS ANTIFOULING FRAKSI DAUN Avicennia marina (API-API) SEBAGAI ANTIFOULING ALAMI PADA MAKROFOULING DI DERMAGA SUNGSANG Ulil Sarifatul Aliyah NIM.08041281722022 RINGKASAN Organisme biofouling secara umum menimbulkan masalah yang merugikan transportasi perkapalan, seperti kerusakan pada lambung kapal, menghancurkan substrat secara terstruktur, tersumbatnya saluran limbah. Permasalahan ini dapat diatasi menggunakan cat antifouling yang biasanya mengandung senyawa trybutyltin (TBT) yang mencegah penempelan biofouling. Senyawa tersebut memiliki efek buruk pada organisme non-target dan terbukti, karena memiliki sifat beracun dan dalam lingkungan laut. Sehingga pengembangan cat antifouling menggunakan senyawa alami sangat dibutuhkan. Senyawa alkaloid, tanin, terpenoid dan steroid beberapa zat alami yang diketahui memiliki efek sebagai antifouling. Avicennia marina merupakan tumbuhan yang memiliki kandungan senyawa alkaloid, saponin, tanin, fenolik, flavonoid, triterpenoid dan glikosida. Penelitian ini bertujuan untuk mengetahui senyawa aktif pada Avicenna marina sebagai alternatif antifouling ramah lingkungan. Penelitian ini dilakukan pada Februari hingga Juni 2021. Metode yang digunakan dalam penelitian ini eksperimental. Berdasarkan penelitian yang telah dilakukan dapat diketahui bahwa, fraksi daun Avicennia marina memiliki senyawa metabolit sekunder. Fraksi metanol mengandung senyawa steroid, flavonoid, saponin. Fraksi n-heksan mengandung senyawa tanin, triterpenoid, alkaloid, flavonoid, saponin, dan fraksi etil asetat mengandung senyawa triterpenoid flavonoid, dan saponin. Berdasarkan hasil uji ANOVA One Way pengaruh konsentrasi serta fraksi metanol, fraksi n-heksan, dan fraksi etil asetat terhadap luas penempelan makrofouling berpengaruh nyata. fraksi metanol dan fraksi etil asetat memiliki persentase luas penempelan diatas 50%, yang artinya nilai tersebut masuk kedalam kategori tinggi. Persentase luas penempelan pada fraksai n-heksan memiliki nilai 46.3% yang artinya memiliki nilai kategori sedang. Makrofouling yang menempel pada plat uji adalah sebagai siput laut (Littoraria angulifera) dan teritip dari (Semibalanus balanoides).
