Abstract

Porang cultivation can be carried out using three planting materials, namely true seeds, bulbils, and cormel, these three planting materials experience dormancy. Potassium Nitrate Solution (KNO3) is a chemical compound that is effective in breaking the dormancy of some plant seeds.This study aims to the effect of shading, soaking with KNO3 and bulbil conditions on the emergence of shoots and the growth of porang plants. The research was conducted in September 2021 to November 2021. The design used was split split plot using three factors, shading (N) as the main plot, namely N0: without shade, N1: 45%, N2: 55%, N3: 80%, KNO3 concentration (K) as subplots, namely K0: Without immersion KNO3, K1: 1500 ppm, K2: 3000 ppm, K3: 4500 ppm and bulbil conditions (D) as sub-sub plots, namely D0: Dormant and D1: Mentis. The data collected included the percentage of shoots emergence, time of shoot emergence, broken petiole sheath, leaf open fully, shoot height, number of shoots, number of leaves, petiole length, petiole diameter, midrib length, leaf width, leaf area and leaf thickness. The results showed that shading 55% and bulbil mentis accelerated the emergence of shoot at 26 DAP and 26.9 DAP, respectively. Soaking in KNO3 solution did not accelerate the emergence of shoots. The emergence of shoots affects the time of petiole sheath break and the leaves open fully, the faster the emergence of shoot, the faster the petiole sheath breaks, the faster the leaves open fully. Shade 80% increases the growth of porang plants with the longest leaf petiole of 22.6 cm; petiole diameter 5.5 mm; midrib length 10.34 cm; the width of the leaflets is 4.7 cm and the leaf area is 183.2 cm², except for the thickness of the leaves.

Abstract

The escalating contamination of heavy metals such as lead (Pb), zinc (Zn), and copper (Cu) in wetland ecosystems poses a significant threat to environmental integrity and public health. This study aims to assess the phytoremediation potential of purun tikus (Eleocharis dulcis) for the accumulation and reduction of these heavy metals in contaminated sediment and water matrices. An experimental approach was employed wherein purun tikus specimens were cultivated for 20 days in media artificially contaminated with varying concentrations of Pb (5, 10, 15 mg/L), Zn (80, 90, 100 mg/L), and Cu (80, 90, 100 mg/L). There was no significant difference (p > 0.05) in the accumulation of heavy metals Pb, Zn, and Cu in the roots, stems, and leaves of purun plants between treatment times of 5, 10, 15, and 20 days. The duration of treatment did not significantly affect the ability of purun plants to accumulate these heavy metals. The descriptive differences seen although not statistically significant are likely due to the small sample size and high variability of the data. The highest removal efficiencies were observed for Pb in stems (95.97%), Zn in roots (81.59%), and Cu in stems (66.10%). These findings indicate that purun tikus exhibits selective metal uptake and distribution mechanisms coupled with high tolerance to heavy metal stress, affirming its efficacy as a phytoremediator for rehabilitating heavy metal-contaminated wetlands and supporting sustainable ecosystem management.

Abstract

Diabetes mellitus is a chronic metabolic disease characterized by hyperglycemia due to impaired secretion or insulin function. Treatment with synthetic drugs often causes side effects so that safer alternatives are needed such as the use of medicinal plants. This study aims to test the potential of mahogany leaf extract (Swietenia mahagoni) as an antidiabetic and determine its optimal dose in mice (Mus musculus) induced by alloxan. The study was conducted in January–March 2025 at the Laboratory of Genetics and Biotechnology and the Laboratory of Animal Biosystematics, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University using the Completely Randomized Design (CRD) method. Mahogany leaf extract was obtained through the maceration method using 96% ethanol solvent. Mice were divided into 5 treatment groups, including negative control (aquadest), positive control (glibenclamide 5 mg), and three groups of mahogany leaf extract doses (70, 140, and 280 mg/kgBW). The results showed that mahogany leaf extract had an effect on reducing blood glucose levels in mice. A dose of 70 mg/kgBW gave the highest effect on reducing blood glucose levels (68%), greater than doses of 140 mg/kgBW (60%) and 280 mg/kgBW (65%). The results of the ANOVA test and further Post-hoc test showed significant differences between treatment groups, where the mahogany leaf extract treatment and positive control treatment were significantly different from the negative control. It can be stated that mahogany leaf extract has the potential as an antidiabetic, and the recommended optimal dose is 70 mg/kgBW.

Abstract

Begomovirus is a genus of viruses that can affect chili plants, causing yellow curly leaf disease. The incidence of yellow curl disease in chili plants was first reported in Indonesia in 2000, and it has been increasing since then. Analyzing the occurrence of yellow curl disease is essential to determine the type of pathogen affecting chili plants and its impact on their growth, chlorophyll levels, and soil nutrients. This research aimed to analyze the incidence of yellow curl disease in the 'Ori 212' variety of chili plants (Capsicum frutescens L.) infected in Kemudo, Prambanan, Klaten. The presence of viral DNA was detected using SPG1 and SPG2 primers. The results revealed that out of 84 chili plants studied, 76 were infected with yellow curl disease, resulting in a disease incidence of 90% and a disease severity of 46%.Infected chili plants exhibited reduced growth, characterized by decreased plant height, leaf width, and leaf length. Additionally, the total chlorophyll levels in infected plants decree sed by 60% compared to healthy ones. Soil analysis indicated high levels of phosphorus (P), while nitrogen (N) and potassium (K) levels were l n conclusion, the research findings confirmed that the chili plants were positively infected with Begomovirus, as evidenced by the high incidence and severity of yellow curl disease, which adversely affected growth and chlorophyll levels. These results underscore the importance of developing sustainable agricultural strategies to mitigate the impact of viral diseases on crop productivity. Future research should explore effective management practices and resistant chili varieties to combat the effects of Begomovirus. .

Abstract

This study aimed to analyze the types of damage to the mangrove forest ecosystem and address abrasion as part of disaster mitigation efforts on Sulamanda Beach, Mata Air Village, Kupang Regency. The research employed a quantitative and qualitative descriptive method using plot sampling for data collection. Observed data included mangrove density, frequency, and Important Value Index (IVI). The results identified six mangrove species: Avicennia marina, Avicennia alba, Lumnitzera racemosa, Rhizophora stylosa, Bruguiera parviflora, and Sonneratia alba. Among these, Bruguiera parviflora had the lowest density (1.7 stands/ha) and relative density (4.52%), while Sonneratia alba showed the lowest frequency (0.7 stands/ha) and relative frequency (12.3%). The IVI analysis revealed Sonneratia alba had the lowest value (14.14), indicating severe damage, primarily due to overharvesting for firewood. In contrast, Avicennia alba and Bruguiera parviflora exhibited the highest IVI values (55.04). These findings reflect the degraded state of mangrove communities, exacerbated by the perception of mangroves as common property with little value, leading to unsustainable exploitation. To mitigate abrasion and restore ecosystem health, community awareness programs and mangrove replanting initiatives are essential.

Abstract

 The search for new therapeutic agents has increasingly focused on bioactive compounds from sponge-associated bacteria. This study investigated bacterial symbionts of marine sponges collected from the mangrove ecosystem of Tanjung Tiram, Southeast Sulawesi, which have not been previously explored for their bioactive potential. Thirty bacterial isolates were screened in triplicate for antibacterial, antioxidant, antidiabetic, and antibiofilm activities. Antibacterial activity was evaluated using the disc diffusion method, antioxidant capacity by DPPH radical scavenging assay, α-glucosidase inhibition for antidiabetic potential, and antibiofilm activity by the crystal violet binding method. Several isolates showed notable bioactivities: strain Sp.8 produced the largest inhibition zone against Escherichia coli (15 mm), and Sp.14 showed the strongest inhibition against Staphylococcus aureus (23 mm). The most active antioxidant strains (Sp.14, Sp.15, Sp.13, and Sp.6) exhibited radical scavenging activity above 80%, while Sp.13, Sp.15, Sp.31, and Sp.37 showed high α-glucosidase inhibition (>74%). Strains Sp.38 and Sp.12 significantly reduced biofilm formation by E. coli and S. aureus, respectively. These findings reveal the untapped potential of sponge-associated marine bacteria from Tanjung Tiram as promising sources of bioactive metabolites for future drug discovery.

Abstract

Mangrove plants are a type of plant that is able to grow in brackish waters in different salinity conditions in the tropics so as to form a unique and distinctive ecosystem. One of the mangrove plants that live in Indonesian waters is the mangrove of the Sonneratia genus. Empirically, parts of the mangrove plant of the Sonneratia sp. species such as fruit, bark, and leaves have been widely used as traditional medicine by the community to treat various diseases and can be used as natural antioxidants that are good for the body. The purpose of this study was to determine and analyze the potential activity of antioxidant compounds from the stem, fruit, and leaf extract of mangrove S. ovata. The antioxidant activity test method used the DPPH method which was measured by the percentage of inhibition and IC₅₀ value. The results of antioxidant activity from several test concentrations of stem, fruit, and leaf extracts obtained a very high percentage of inhibition so that the antioxidant compounds contained in the three samples could reduce free radical activity. Fruit samples had the highest antioxidant potential with an IC₅₀ value of 4.59 ppm, followed by leaf samples at 25.39 ppm and stem samples at 45.91 ppm. Thus, mangroves of the S. ovata species have the potential as natural antioxidants that are good for the body and only require <50 ppm to reduce free radicals by 50%.

Abstract

Ornamental plants are important horticultural commodities with considerable economic value, providing income for both growers and traders. Among them, Sansevieria trifasciata (commonly known as snake plant) is favored for its sword-shaped, rigid leaves. This study aimed to assess the incidence and intensity of disease in snake plants. The research was conducted from January to February 2025 using purposive sampling. Field observations revealed that the plants were affected by Colletotrichum sansevieria, causing necrotic black lesions. Disease incidence and intensity varied across locations, with the highest incidence (100%) observed in plants owned by Suwaji, Salikun, and Asep, and the lowest (10%) in those owned by Tina Purba and Sarkun. Disease intensity was greatest at Suwaji’s site (83.3%) and lowest at Tina Purba’s and Sarkun’s (3.3%). These differences were influenced by environmental factors such as temperature and humidity. Integrated disease management through physical, chemical, and biological methods is suggested as a strategy to suppress pathogen growth.

Abstract

The efforts to improve land use efficiency to increase food crop production can be done with an intercropping system. Intercropping can be done with a food crop and horticultural crop planting system, such as corn and spinach. The purpose of this study was to determine the effect of coffee skin compost on the growth and production of corn and spinach in an intercropping system. The research method used a Randomized Block Design (RBD). The treatment factor were the dose of coffee skin composts consisting of 5 treatments, each treatment repeated 3 times. The treatments used were P0: (Control without treatment) P1: 4 tons/ha of coffee skin compost (2.5 kg/plot) P2: 4.6 tons/ha of coffee skin compost (3 kg/plot) P3: 5.2 tons/ha of coffee skin compost (3.5 kg/plot) P4: 6 tons/ha of coffee skin compost (4 kg/plot). Based on the research results, it was known that intercropping of corn and spinach with the application of coffee skin compost did not have a significant effect on the growth and yield of corn plants. While in spinach plants, the application of coffe skin compost had a significant influence on growth parameters,  namely plant height, leaf length and width per week. However, other variables, such as the number of leaf and spinach harvest did not show significant efect. This showed that coffee skin compost tends to affect spinach growth more than corn in the intercropping system. Although the effect on corn was not statistically significant, the highest mean values ​​were observed at P3 (5.2 tons/ha) and P4 (6 tons/ha) treatments  in corn and spinach intercropping.
