Abstract

Rhizophora stylosa is a type of mangrove used for various purposes, including as a source of charcoal and firewood. This type of mangrove is also used in traditional medicines for mangosteen, wounds, toothache, lucid, liver, and itching. It is possible because these species contain secondary metabolites (bioactive). This study aimed to identify secondary metabolites from the root extract of Rhizophora stylosa accession from Morotai Island. Root samples of R. stylosa were obtained from Pandanga Village, South Morotai, Morotai Island. Extraction by maceration using methanol. Secondary metabolites are identified qualitatively, including alkaloids, saponins, flavonoids, triterpenoids, and steroids. The yield of the methanol extract of Rhizophora stylosa root was determined to be 26.42%, with a dry paste-like consistency. Alkaloids and saponins were the secondary metabolite compounds identified in the extract.

Abstract

One of Indonesia's potentially rich plant species is the rambai (Baccaurea motleyana Muell.Arg). The rambai (Baccaurea motleyana Muell.Arg) belongs to a group of fruit-producing plants that grow wildly in Southeast Asian territories, such as Thailand, Malaysia, and Indonesia, particularly in Sumatra and Kalimantan. Closely related to the menteng/kepundung fruit family, the rambai plant is also found in the Aceh region. Known locally as rambe, it grows in the wild and has not been specifically cultivated. The fruit, along with its skin and seeds, has not been utilized specifically by the community for medicinal purposes, making this research significant. Furthermore, there has been no study on the phytochemical screening of various phytochemical contents in the skin and seeds of the rambai fruit. The objective of this study is to qualitatively determine the phytochemical screening results and contents in the ethanol extract of the skin and seeds of the rambai fruit (Baccaurea motleyana Muell. Arg). This research aims to add to the information on the phytochemical richness of the rambai fruit and serve as an initial reference for studies on the extracts of the fruit's skin, seeds, and flesh (Baccaurea motleyana Muell.Arg). The method for preparing the ethanol extract of the skin, seeds, and flesh of the rambai fruit was carried out through maceration using 96% alcohol solvent. The findings of this study indicate that the ethanol extracts of the fruit's skin and seeds contain the same chemical compounds, namely terpenoids, saponins, flavonoids, and phenolics/tannins.

Abstract

Perkembangan teknologi bioproses telah mendorong pendekatan ke arah produk surfaktan biologi (biosurfaktan) yang ramah lingkungan. Penelitian ini difokuskan pada optimasi produksi biosurfaktan dengan menggunakan variasi sumber karbon dan nitrogen. Tahap awal penelitian ini dilakukan dengan menguji potensi bakteri Chromohalobacter japonicus BK-AB18 penghasil biosurfaktan dengan menggunakan metode uji hemolisis dimana hasil menunjukkan aktivitas hemolisis yang tinggi dengan ukuran zona bening 3 cm pada media agar darah. Selanjutnya dilakukan produksi pada medium optimal dengan menambahkan 2% variasi sumber karbon terdiri dari minyak zaitun, minyak jagung, minyak kelapa sawit, minyak kacang kedelai dan minyak bunga matahari serta 0,3 % variasi nitrogen terdiri dari urea, NaNO3, NH4Cl, NH2(SO)4 and KNO3. Hasil penelitian menunjukkan produksi biosurfaktan dari Chromohalobacter japonicus BK-AB18 meningkat secara signifikan dengan menggunakan minyak zaitun sebagai sumber karbon dan urea sebagai sumber nitrogen dengan hasil penyebaran minyak 4,8 cm serta aktivitas biosurfaktan dengan nilai tegangan permukaan sebesar 34 dyne/cm, dan hasil uji emulsifikasi sebesar 76%.
