Abstract

The purpose of this study was to identify various types of epiphytic Pteridophytes and their host trees. This study used an exploration method or direct exploration method and obtained the types of Pteridophytes found in the Paninggaran Village Forest. Plant observations were carried out by observing morphological characters in plants including leaf shape, leaf color, leaf length, and leaf width. The identification results were then matched with references, namely Flora books, Plant Taxonomy, and Plant Morphology. The application used Google Lens and the Global Biodiversity Information Facility/GBIF website. Plant observations were carried out by observing morphological characters in plants including leaf shape, leaf color, leaf length, and leaf width. Based on the results of the study, 10 species were found in the Paninggaran Village Forest and divided into 7 families and 5 types of host plants.

Abstract

The development of degenerative diseases is influenced by oxidative stress, which stems from an imbalance between free radicals and the body’s antioxidant defenses. Therefore, natural antioxidant supplementation is considered an essential preventive strategy. Chives leaves (Allium schoenoprasum) are functional foods containing various bioactive compounds; however, their potential as natural antioxidants remains underexplored. This study aims to evaluate the antioxidant activity and toxicity profile of the extract through in vitro assays. The extraction process using maceration and percolation techniques with methanol as the solvent. The analytical procedures encompassed phytochemical profiling, quantification of total phenolic compounds using the Folin–Ciocalteu reagent, and antioxidant capacity evaluations utilizing the Ferric Reducing Antioxidant Power (FRAP) and ABTS (2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)). The resulting total phenolic content of 439.45 μg/mL, equivalent to 14.65 mg gallic acid equivalent (GAE) per gram of dry weight (DW). The IC₅₀ values were 21.93 μg/mL (ABTS) and 13.06 μg/mL (FRAP), indicating strong antioxidant activity. Toxicity assessment using the Brine Shrimp Lethality Test yielded an LC₅₀ value of 333.86 μg/mL, suggesting low toxicity.  These results indicate that the extract holds a great promise as a safe and effective source of natural antioxidants.

Abstract

The decline in pineapple production in Lampung Tengah regency occurred in 2023, where the decline reached 16.4% of the pineapple production in 2022 (8.6 million quintals). The decline in pineapple production came from PT Great Giant Pineapple (PT GGP), with the problem of accumulation of pineapple plant litter polymers on ultisol land. The solution that emerged was the adding of biochar, vermicompost and Azotobacter (LOB), with various plowing depth. The aim of this research was to determine the dynamics of Azotobacter population (log CFU g-1) in the ultisol soil of PT GGP’s pineapple plantations which were influenced by plowing depth, compost mixture and interaction between them. The supporting variables were the temperature (0C), water content (%), pH and soil organic carbon (%). Data analysis included ANOVA (α 5%), Tukey’s HSD Test (α 5%) and Pearson R Test (α 1%). The results showed that the Azotobacter population in pre-planting (PT) samples differed significantly between plowing depth, compost mixture and the interaction of the two factors. Deep plow treatment (± 40 cm) with finely chopped pineapple litter (L1) and application of premium GGP’s compost + LOB (P3) was the best treatment, with 4,96 log CFU g-1 Azotobacter population. Azotobacter population correlated not significantly with any supporting variables.

Abstract

Sugarcane has been widely used to treat various diseases due to its metabolite content. Tissue culture is one method that can be used to produce metabolites and is an alternative biotechnology as a conservation strategy. This study aims to analyze the differences in metabolite content in sugarcane plantlets cultured with different media and subculture frequencies. Plantlets were extracted using the maceration method with 70% p.a. ethanol solvent. Metabolite analysis was carried out using a Gas Chromatography-Mass Spectrometry (GC-MS) instrument. Metabolite identification was carried out based on the NIST library. The results showed that the 10th subculture of sugarcane plantlets cultured on MS+Kinetin+Coconut Water media contained 5 metabolites, while the 11th subculture of plantlets cultured on MS+Kinetin+Tidiazuron media contained 7 metabolites. Differences in the type and number of metabolites indicate the influence of culture conditions on the metabolite profile of the plantlets. This study provides an initial overview of the potential of sugarcane tissue culture in the production of secondary metabolites.

Abstract

Medicinal plants have long been used in traditional medicine as part of healing and disease prevention practices. The Malay ethnic group possesses inherited ethnobotanical knowledge regarding the use of medicinal plants. This study aims to identify the types of plants used as medicine and their applications by the Malay community in Bagan Percut Village, Percut Sei Tuan District, Deli Serdang Regency, North Sumatra. A qualitative and quantitative descriptive approach was employed through interviews with 50 respondents and 10 key informants possessing local knowledge of medicinal plants. The results revealed 65 medicinal plant species belonging to 35 sukues, with the dominant ones being Zingiberaceae (6 species), Solanaceae (5 species), and Fabaceae (5 species). The most frequently used plant parts were leaves (46%), fruits (28%), and rhizomes (9%). The most common method of preparation was boiling (29%), while the most common mode of use was oral consumption (48%). Herbaceous plants constituted the most utilized growth form (31%). The purposes of plant utilization included treatment (61.53%), care (24.6%), and general health improvement (13.8%). This study highlights the importance of preserving traditional ethnobotanical knowledge among the Malay community.
