Abstract

This study aimed to identify the composition of flora species in Tabebuya Park, analyze the biocultural potential of its flora, and explain its implications for strengthening the ecological, social, and cultural functions of urban green open spaces. The main issue underlying this study is the lack of integrated information on species composition and the biocultural use potential of flora in urban parks as a basis for urban green space management. The study employed an exploratory approach using the cruise method through direct inventory of all vegetation at the study site. Species identification was conducted based on morphological observations, visual documentation, and the use of an artificial intelligence (AI)-based plant identification application as a preliminary tool, which was subsequently verified using botanical literature and taxonomic references. Data were analyzed descriptively and quantitatively by calculating relative frequency and grouping plants according to ethnobotanical use categories derived from the literature. The results showed that Tabebuya Park contains 53 plant species from 34 families, with high multifunctional potential, including 42 medicinal species, 31 ornamental plants, 9 aromatic plants, 2 dye-producing plants, 21 food and beverage plants, 5 culinary spice plants, 20 cosmetic plants, and 10 plants used for rituals or customary practices. These findings confirm that Tabebuya Park functions not only as an aesthetic element of the urban landscape, but also as a biocultural green space that plays an important role in providing ecosystem services, supporting educational activities, and improving the quality of life of urban communities.

Abstract

Bacterial infections caused by Staphylococcus aureus and Salmonella typhimurium remain a global health problem, particularly with increasing antibiotic resistance. This study aims to analyze the phytochemical profile and test the antibacterial activity of angsana (Pterocarpus indicus) leaf extract against these two bacteria. The study used an experimental method with a Completely Randomized Design (CRD) consisting of four extract concentrations (10%, 20%, 40%, and 80%), a positive control (chloramphenicol), and a negative control (DMSO), each with six replications. Antibacterial activity was tested using the Kirby-Bauer disc diffusion method, with the observation parameter being the diameter of the inhibition zone. The results showed that angsana leaf extract had concentration-dependent antibacterial activity against Staphylococcus aureus and Salmonella typhimurium, with the highest inhibition at 80% concentration of 19.69 mm and 19.24 mm, respectively (strong category). Comparatively, Salmonella typhimurium was more sensitive at medium concentrations, while Staphylococcus aureus showed a higher response at maximum concentrations. Although the extract's activity was still lower than chloramphenicol, these results demonstrate the potential of angsana leaf extract as a broad-spectrum antibacterial agent against both Gram-positive and Gram-negative bacteria. Therefore, angsana leaf extract has the potential to be developed as an alternative or complementary therapy in controlling bacterial infections, although further research is needed to optimize its effectiveness and further examine its mechanism of action.

Abstract

Indonesia memiliki keanekaragaman hayati tertinggi di dunia, salah satunya adalah tanaman Canna. Canna indica L. dikenal sebagai tanaman ganyong sering dimanfaatkan sebagai bahan pangan karena termasuk golongan umbi-umbian. Selain umbi, bagian lain pada tanaman ini yang memiliki potensi lain adalah daun yang juga memiliki potensi sebagai herbal. Tanaman ganyong diketahui dapat tumbuh di bawah naungan pohon lain. Naungan pada suatu tanaman dapat memengaruhi kondisi serta senyawa yang terkandung. Penelitian ini bertujuan untuk mengidentifikasi kandungan metabolit sekunder pada daun ternaung dan tidak ternaung. Metode yang digunakan untuk mendapatkan ekstrak etanol daun Canna indica L adalah maserasi. Hasil penelitian yang diperoleh pada daun dengan naungan didapati mengandung metabolit sekunder meliputi flavonoid, alkaloid, polifenol, saponin, glikosida dan tanin. Hasil kandungan metabolit sekunder pada daun tidak ternaung meliputi kandungan yaitu alkaloid, polifenol, saponin, glikosida dan tanin.Kata Kunci - Canna indica L., Ganyong, Metabolit sekunder.
