Abstract

Mangrove ecosystems are coastal ecosystems strongly influenced by salinity, which affects plant adaptation. Pangandaran Regency has mangrove areas with different salinity conditions that may influence the morphological and anatomical characteristics of Sonneratia alba Sm. This study aimed to analyze leaf area and thickness, stomatal characteristics, trichomes, chlorophyll content, and salt accumulation in Sonneratia alba leaves from Bulaksetra and Bojongsalawe. A qualitative and  quantitative approach was used through leaf morphological and anatomical analysis, as well as measurements of chlorophyll content and salt concentration. The results showed that leaf area and thickness did not differ significantly between locations. Stomatal density was significantly lower under high salinity (28.841 cells/mm²) compared to low salinity (40.765 cells/mm²) (p = 0.024), and chlorophyll content was also lower under high salinity (32.167 CCI) compared to low salinity (47.333 CCI) (p = 0.011). Unicellular non-glandular trichomes were found on the adaxial leaf surface of Sonneratia alba, helping reduce water loss and light exposure. Salt accumulation was higher under high salinity as an adaptive mechanism to maintain osmotic balance and reduce toxicity. Sonneratia alba shows ecophysiological plasticity in response to salinity through physiological and anatomical adjustments, especially in stomata and chlorophyll content. These findings highlight the importance of adaptive mechanisms Sonneratia alba for mangrove conservation and rehabilitation in coastal areas.

Abstract

Cicalengka Biodiversity Park (Kehati) is a conservation area with great potential for preserving local flora and fauna, especially in Kampung Ciseupang. The community’s knowledge of utilizing traditional medicinal plants is an important local wisdom that supports conservation efforts. This study aims to identify the types, uses, processing methods, and plant parts utilized by the Kampung Ciseupang community for traditional medicine, as well as to identify the distribution of medicinal plant families in Kehati Cicalengka. The method used was qualitative descriptive through semi-structured interviews, with informants selected by purposive sampling. Data collection techniques included direct observation, exploration, and documentation. Based on exploration results, 126 species of medicinal plants from 48 families were found in Kehati Cicalengka, dominated by Fabaceae, Euphorbiaceae, and Malvaceae families. Interviews showed that 67 plant species utilized by the community as traditional medicine come from 33 different families, with Lamiaceae, Asteraceae, and Myrtaceae as the most abundant families. The most frequently used plant part was the leaf, commonly processed by boiling as a simple extraction method. The use of medicinal plants is mostly aimed at treating skin diseases. This study reveals that local knowledge passed down through generations plays an important role in conserving medicinal plants and maintaining sustainable local wisdom.
