Abstract

Background: Mangrove ecosystems are globally significant for biodiversity, carbon storage, and coastal protection, yet they are increasingly threatened by anthropogenic activities. Indonesia, which hosts the world’s largest mangrove area, also experiences one of the highest degradation rates, making site-specific assessments essential. This study investigates the stand structure and degradation level of mangrove vegetation in Pongkar Village, Karimun Regency, Riau Islands Province, where ecological importance intersects with human pressures. Methodolgy: Field surveys were conducted using five 100 m transects with 10 × 10 m plots for vegetation analysis and a 1 ha plot to assess degradation levels following the Indonesian Ministry of Environment Decree No. 201/2004. Vegetation parameters, including density, frequency, dominance, and Importance Value Index (IVI), were measured. Results: Nine mangrove species were identified, comprising seven true mangroves and two associated species. Rhizophora apiculata dominated the community (density 0.078 ind/m²; IVI 121.15%). Diversity indices revealed medium diversity (H′ = 1.45–1.89), low to medium richness (Dmg = 1.28–1.78), high evenness (E = 0.81–0.86), and low dominance (D = 0.18–0.26). Stand density reached 1,181 trees/ha, classified as medium.These results suggest that ecological functions remain active, but moderate diversity and richness indicate vulnerability to disturbance and degradation risks. Contribution: The study provides empirical evidence to inform conservation planning, emphasizing the need for regular monitoring, rehabilitation of underrepresented species, and community-based management to sustain the Pongkar mangrove ecosystem

Abstract

Background: The physical characteristics of soil under different land uses influence its potential for optimal productivity. Wotan Village, located in Panceng District, Gresik Regency (part of the northern limestone mountains), can maximize land use by considering the type of crops and land suitability based on soil physical properties. The mismatch in land use in Wotan Village is likely due to poor soil physical properties, as the soil is formed from weathered limestone. Limestone soils are dominated by fine fractions in their texture, and their texture and structure are generally unsuitable for use as planting media. This study aims to analyze the physical characteristics of soils under various land-use types and to determine the effect of different land uses on soil physical properties. Methodology: The research employed a purposive sampling method. Soil samples were collected from three types of land use: plantation, dryland farming, and rainfed rice fields, at two depths (0-20 cm and 20-40 cm) with five replications. Laboratory analyses were conducted on soil physical parameters, including texture, bulk density, particle density, total pore space, and permeability. Findings: The results showed that the soils in the three land-use types had clay loam, silty clay, and clay textures. Bulk density ranged from 1.10 to 1.24 g/cm³ for rainfed rice fields at a depth of 20 cm. Particle density ranged from 2.46 to 2.603 g/cm³. Total pore space ranged from 52.46% to 56.31%. Permeability ranged between 0.80 and 1.21 cm/hour, classified as moderately slow. Differences in land use had no significant effect on soil physical properties. Contribution: The findings provide a reference for farmers regarding the physical properties of soils in limestone areas

Abstract

Background: Injuries represent a major health concern in Indonesia, with the national health survey in 2022 reporting ~9% prevalence. In 2023, >146,000 traffic accident injuries and >370,000 occupational accidents were recorded, highlighting the urgent need for affordable and effective wound care solutions, particularly in underserved areas. Methods: Polyvinyl alcohol (PVA)–chitosan hydrogels were prepared via freeze–thaw crosslinking, incorporating Piper betle extract at 0.5%, 1%, and 2% w/w (F1–F3) alongside a control (F0). Physicochemical characterization included Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), swelling ratio, mechanical strength, water vapor transmission rate, and water resistance. Biological performance was assessed through antimicrobial testing (Staphylococcus aureus, Escherichia coli), fibroblast cytocompatibility assays, and in vitro release studies. Each assay was conducted in triplicate (n ≥ 3), and statistical analyses applied repeated-measures ANOVA or Friedman test (p < 0.05). Results: Hydrogels exhibited waterproof integrity and high exudate absorption (>400%), maintaining a moist wound environment. Antimicrobial assays showed clear inhibition zones (~15 mm) in Piper betle –loaded formulations, significantly greater than F0. Fibroblast viability exceeded 85%, confirming good cytocompatibility. In vitro release profiles demonstrated sustained bioactive release consistent with the Higuchi model. The combination of PVA–chitosan matrix and Piper betle extract produced hydrogels with stable physicochemical properties, controlled release kinetics, and potent antimicrobial activity, while remaining biocompatible.  Contributions: These findings support the potential of PVA–chitosan/Piper betle hydrogels as cost-effective wound dressings. Their clinical applicability is particularly relevant in rural and resource-limited healthcare settings in Indonesia, where the burden of injury and demand for accessible wound care products remain high

Abstract

Background: Plastic that accumulates in the environment over extended periods can fragment into smaller particles known as microplastics. The uncontrolled buildup of microplastics poses significant risks, including harmful health effects on living organisms and negative impacts on ecosystems. One promising sustainable solution under investigation is the use of gut bacteria from mealworm (Tenebrio molitor) for plastic biodegradation. This study aims to identify the gut bacterial species involved in degrading plastics ingested by mealworm fed with Polystyrene (PS), Polyethylene (PE), and Polyethylene Terephthalate (PET), and to evaluate the degradation rate exhibited by these bacteria. Methodology: Bacterial isolation was carried out from the gut of mealworm that were fed plastic for 30 days, using Mineral Salts Medium (MSM) as a selective medium, followed by testing the plastic degradation potential of the isolated gut bacteria. The microbial species involved were identified using the VITEX-2 Compact System. Findings: Bacteria isolated from the digestive tract of mealworm showed significant potential in degrading plastics. Pseudomonas aeruginosa was found in PS and PE treatments with degradation rates of 14.4% and 44.4%, respectively, while Aeromonas salmonicida was identified in the PET treatment with a degradation rate of 16.3%. Contribution: These findings highlight the role of mealworm gut microbes in degrading PS, PE, and PET, supporting their potential as eco-friendly biodegradation agents

Abstract

Background: Understanding the relationship between body length and weight in commercially essential shrimp species is crucial for assessing growth patterns and estimating biomass. This study aims to evaluate the relationship between body length and weight in three species of shrimp, namely the whiteleg shrimp (Penaeus merguensis), whiteleg shrimp (Litopenaeus vannamei), and tiger shrimp (Penaeus monodon), as a basis for fisheries management in the waters of Jaloh Island, Batam City. Methodology: The samples were collected randomly from the results, catching fishermen at three stations during a day of data collection. Morphometric measurements were conducted on 180 individual, namely whiteleg shrimp (P. merguensis), White shrimp (L. vannamei), and Tiger shrimp (P. monodon). The length-weight relationship has been analyzed for a long time using simple regression using Excel software. The connection between character morphometrics and total length was analyzed with ANCOVA using SPSS 27 software. Findings: The results showed the determinant coefficient of three species shrimp in this study indicates a very close relationship between the growth of length and weight of shrimp. In the P. monodon species, it is known that approximately 78 % of the weight gain is attributed to the increase in shrimp length, while 22 % is attributed to other factors. Characters that influence the total length of the three species are generally overall, where P. merguensis is more influenced by the tail and weight, L. vannamei by the front, back, and body mass, while P. monodon involves almost all parts of the body. Contribution: This approach helps estimate biomass, identify morphological variations between species, and provides a scientific basis in supporting efforts to manage shrimp resources sustainably

Abstract

Background: This Research aims to evaluate the effect of humic acid and gypsum application on organic matter availability and the yield of tomato plants cultivated on mangrove forest soil. Methods: The research employed a Completely Randomized Design (CRD) in factorial pattern involving two primary factors. Results: Indicate that applying humic acid (1,124 g) and gypsum (18,75 g) can significantly influence the growth, productivity, and nitrogen uptake in tomato plants. Furthermore, the combination treatments of H3G3 (humic acid 0,124 g and gypsum 18,75 g) and H3G4 (humic acid 0,124 g and gypsum 25 g) yielded the highest number of tomato fruits, at 14.33 fruits. Additionally, the highest Vitamin C content (37,84 %) was detected in tomato fruits from the 0,124 g humic acid treatment. Conclusions: The combination of humic acid and gypsum significantly improves mangrove soil conditions by reducing salinity and increasing essential macronutriens like nitrogen and phosphorus. This synergy enhances nutrient retention and uptake, while gypsum supplies calcium and sulfur to correct acidic of saline soils. As a result, it creates a more fertile environment that supports healthy tomato growth and improves both yield quality and quantity.
