Abstract

River pollution is a special concern in environmental studies due to human waste disposal, while the rivers are still the main source for anthropogenic activities of the community. Population growth in Bandung City (2.26% annually) has intensified these activities, contributing to water pollution in the Cidurian River, a vital 24.86 km waterway in West Java. Improper waste management and agricultural runoff have further degraded water quality, affecting aquatic life, including plankton. This study was conducted to analyze the abundance and diversity of plankton as aquatic bioindicators in the Cidurian River. Sampling was conducted at four stations consisting of nine plots selected based on purposive sampling method with three repetitions. The results revealed 26 species of phytoplankton and 11 species of zooplankton. The highest abundance of phytoplankton and zooplankton was found at station 1, with values of 130 cells/L and 56 individuals/L respectively. Chlorophyceae was the most frequently observed class at all stations. Ecological analysis using the Shannon-Wiener Diversity Index showed the highest values at station 1, with phytoplankton H’=2.21 and zooplankton H’=0.79, while the lowest species dominance was observed at stations 3 and 4. Environmental parameters indicated variations among stations. Based on the data, the water quality of the Cidurian

Abstract

Planting media and micronutrients are important aspects of plant growth. Planting media rich in organic matter and micronutrients such as B and Cu are essential nutrients that must be fulfilled for oil palm plants (Elaeis guineensis Jacq). This study aims to determine the growth of oil palm in early nurseries with the composition of planting media and the concentration of microfertilizer application and determine the best treatment interaction for oil palm seedling growth. The research was conducted at UPT BPP Tungkal Jaya Kec. Musi Banyuasin from December 2023 to March 2024. The design used was a two-factor Randomized Block Design with three replications, each replication consisting of 48 plants so that there were 144 experimental units. The treatments consisted of (M0P0) 100% soil + 0 ml/plant vs (M1P1) 85% soil + 15% rice husk charcoal + 2 ml/plant vs (M2P2) 75% soil + 25% rice husk charcoal + 4 ml/plant and (M3P3) 50% soil + 50% rice husk charcoal + 6 ml/plant. The data obtained were analyzed using ANOVA, if there was a significant effect, it was continued with the Honest Real Difference test at the 5% level. The results showed that the composition of planting media had a significant effect on oil palm growth such as stem diameter, number of leaves, plant height, wet weight, dry weight and root length. However, microfertilizer concentration did not show a significant impact on growth. The interaction between growing media and microfertilizer affected certain variables such as leaf area, wet weight and root length.The conclusion of this research is that M3 planting media and P3 microfertilizer are effective in increasing the growth of oil palm seedlings. The use of organic planting media, loose and providing sufficient nutrients for plants found in the community environment

Abstract

Open-pit coal mining damages habitat, alters soil, and lowers biodiversity, therefore harming the ecosystem. Efforts at land reclamation involving topsoil restoration and regrowth are very vital for ecological recovery. This study uses soil insect diversity as a bioindicator of West Banko area PT Bukit Asam, South Sumatera, reclamation success. Soil insects were collected using combinations of soil extraction and forest floor collection methods along transect lines. Environmental factors like soil temperature, pH, humidity, and light intensity were measured to determine habitat conditions. Data demonstrates that Formicidae (Camponotus spp.) dominates the total of 154 soil insect individuals across eight genera, four families, and three orders. Considering excellent development in the restoration effort, the Shannon-Wiener diversity index (H') = 1.80656 indicates a minor degree of biodiversity. But the preponderance of monoculture Eucalyptus plants may limit insect diversity. increased soil humidity levels (60–80%) linked with increased insect population, therefore underlining the significance of soil moisture in the regeneration of ecosystems. The findings underline the need for different vegetation in reclamation strategies to help in better ecological balance and biodiversity. This study would be rather helpful for policymakers to focus on land restoration projects for ecologically acceptable post-mining ecosystem regeneration.

Abstract

The Environmental pollution caused by industrial waste including oil spills have become a global issue that requires effective and environmentally friendly solutions. Bioremediation used by bacteria immobilized has been develop as a promising method for pollutant degradation, because it can increase the stability and activity of microorganism under various condition in the environment. This study is a systematic review to evaluate various immobilized technique including adsorption, entrapment, adsorption-embedding, cross linking and the techniques effectiveness in hydrocarbon, crude oil, and heavy metals remediation. This review collates a vast amount of existing literature on the myriad contaminants treated using immobilized bacteria. Based on the reviewed article, the immobilization techniques such as adsorption, adsorption-embedding, entrapment and cross-linking were frequently reported to enhance degradation performance, particularly in crude oil bioremediation. The techniques consistently demonstrated high effectiveness in pollutant degradation across different environmental conditions. The environmental factors, including pH, pollutant concentration and surfactant availability have an important role in the success of bioremediation. Although, this technology enhances bacterial resilience and biodegradation efficiency, the challenges such as the hight cost of immobilization materials and limitations in extreme environment application remain a problem. The optimization techniques and immobilized materials has the potential to provide a sustainable solution for pollutant bioremediation in the environment

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.
