Abstract

The Mangrove Forest Nature Reserve East Coast (CAHBPT) in Jambi Province has functions, one of which is to improve water quality by absorbing dangerous heavy metals such as Pb and Cu which come from various human activities around the waters. This absorption can be done by using hyperaccumulator plants such as Rhizophora apiculata Blume. This study aims to determine the potential and mechanism of R. apiculata in the phytoremediation of heavy metals Pb and Cu in the CAHBPT area, Alang-Alang Village, Tanjung Jabung Timur Regency, Jambi Province. Sampling was carried out using the purposive sampling method at three stations. The calculation of the Bioconcentration Factor (BCF) aims to determine the potential of R. apiculata in phytoremediation Pb and Cu metals, as well as the calculation of the Translocation Factor (TF) to determine the phytoremediation mechanism of R. apiculata. The results of this research found that the accumulation of Pb and Cu metals in sediments ranged from 11.04-12.36 mg/kg and 7.93-9.08 mg/kg. The accumulation of Pb and Cu metals in the roots of R. apiculata ranges from 2.34-2.65 mg/kg and 1.56-2.93 mg/kg. The accumulation of Pb and Cu metals in the shoots of R. apiculata ranged from 2.77-3.16 mg/kg and 0.61-1.05 mg/kg. The phytoremediation potential of R. apiculata at the research site is included in the excluder category or plants still limit the accumulation of heavy metals entering the body (BCF<1). R. apiculata at the research site translocated Pb metal using a phytoextraction mechanism (TF>1) and Cu metal using a phytostabilization mechanism (TF<1).

Abstract

Leea indica (Burm.f.) Merr, commonly known as Memaye, is a shrub utilized by the Besemah tribe in Lahat Regency, South Sumatra, for treating infectious diseases such as hepatitis and warts, as well as degenerative diseases like liver disorders. This plant's medicinal properties are primarily derived from its roots and fruits, which contain secondary metabolites like alkaloids, flavonoids, and terpenoids. Anatomical studies are crucial to identify specific structures within the plant that may store these metabolite compounds. This research aims to analyze the anatomical structure and distribution of secretory structures in the vegetative organs (leaves, stems, and roots) of Leea indica. Using a descriptive method, the study employed Paraffin and Whole mount techniques to prepare samples for microscopic observation. Results revealed the presence of epidermal tissue, basic tissue, and vascular tissue. Additionally, internal secretory structures, including cavities and two types of idioblast cells, were found to function as storage sites for secondary metabolites. These secretory structures were distributed throughout the leaves, stems, and roots of the plant.
