Abstract

An indicator of the stability of a community within an ecosystem is diversity of species. The absence of data regarding the species diversity in the campus forest of UIN Sulthan Thaha Saifuddin Jambi prompted the conduct of this study, which aimed to identify tree types and calculate the diversity index and evenness index for the campus forest. To achieve this aim, the research site was selected through the implementation of purposive sampling, whereas the plot was determined through the utilization of systematic sampling. Aside from that, tree data was collected in 22 plots using a quadratic method with dimensions of 20 m x 20 m. The research findings revealed the acquisition of 83 tree species, comprising 30 families and a total of 464/8.62 ha individuals. The species of tree that contains the greatest number of individuals is Ixonanthes sp. The genus Ixonanthes exhibited the greatest INP, which measured 37.64%. At 3.70, the species diversity index (H') indicates a significant degree of diversity across categories. Furthermore, the evenness index (E) acquired a value of 0.84, placing it within the category of high evenness

Abstract

Seedlings are the first stands that grow to replace damaged forest vegetation. Seedlings can have a positive impact on the balance of the wider ecosystem, because seedlings are the beginning of an ecosystem regeneration process that is greatly influenced by that ecosystem The purpose of this research to information regarding the structure and composition of seedling in the UIN Sulthan Thaha Saifuddin Jambi Campus Forest. This research was carried out in July 2022 – March 2023. The research location was determined using the Purposive Sampling Method, determining the plot using systematic sampling, and data collection using the quadratic method with a size of 2 m x 2 m. The observation results were analyzed using the Importance Value Index, Shannon-Winner Diversity Index, Morisita Index, and the Evenness Index. The research results found that there were 332 individuals, 84 types of seedlings, belonging to 28 families. The highest Importance Value Index (INP) is Gmelina arborea Roxb (11.19%), the Diversity Index (H') is in the high category (H' 3.94). The evenness index (E) (0.89) is in the high (even) category.

Abstract

Tanah menjadi salah satu habitat mikroorganisme yang berperan penting dalam dekomposisi bahan organik, termasuk selulosa. Lingkungan tanah di sekitar kandang ayam mengandung bahan organik tinggi dan berpotensi sebagai sumber bakteri pendegradasi selulosa. Penelitian ini bertujuan mengidentifikasi karakteristik bakteri tanah di Muaro Jambi sebagai kontribusi dalam kajian mikrobiologi tanah. Metode penelitian meliputi pengambilan sampel tanah, pengenceran bertingkat, teknik kultur dengan metode spread plate, serta pewarnaan Gram untuk membedakan bakteri Gram positif dan Gram negatif berdasarkan morfologi dan sifat dinding selnya. Hasil penelitian menunjukkan bahwa bakteri gram negatif mendominasi hingga 80% dibandingkan bakteri gram negatif. Bakteri gram negatif yang ditandai dengan warna merah pada pewarnaan Gram, sementara bakteri Gram positif memiliki warna ungu. Morfologi bakteri yang teramati meliputi bentuk coccus dan bacil, menunjukkan adaptasi yang beragam terhadap lingkungan tanah. Temuan ini mengindikasikan keberadaan mikroorganisme yang berpotensi menghasilkan senyawa pendegradasi bahan organik yang sulit dipecah seperti selulosa dan berkontribusi terhadap proses dekomposisi di lingkungan tanah sekitar kandang ayam. Penelitian ini memberikan dasar awal untuk studi lebih lanjut mengenai potensi aktivitas enzimatik bakteri tanah dalam konteks mikrobiologi lingkungan.

Abstract

Background: Water bodies are highly susceptible to contamination from various sources, including domestic, agricultural, and industrial waste. These contaminants often introduce pathogenic microorganisms such as Escherichia coli and Salmonella sp., which pose significant risks to human and animal health. Despite this, bacteria also play a vital role in supporting aquatic ecosystems by facilitating the decomposition of organic matter. Methodology: This study was conducted with the objective of isolating and characterizing bacterial species present in the waters of Campus A Lake. Sampling was carried out by collecting water from several points within the lake. Bacterial isolation was performed using the serial dilution technique, followed by inoculation on Nutrient Agar (NA) media and incubation at 37 °C for 24 hours. The characterization phase included morphological observation of colonies, Gram staining, and biochemical tests such as oxidase reactions. Findings: The study successfully isolated three distinct bacterial colonies. One isolate exhibited a rod-shaped (bacillus) morphology, while the remaining two showed a spherical (coccus) form. All isolates tested Gram-negative, evidenced by the pink coloration after staining. Importantly, most of the isolates demonstrated an ability to break down organic material, indicating their usefulness in environmental cleanup. Additionally, the introduction of Eco Enzyme into lake water positively influenced the microbial ecosystem by promoting the growth of beneficial decomposers like Bacillus sp. and Lactobacillus sp., while simultaneously suppressing pathogenic bacteria. Contribution: These findings provide valuable insight for future water quality management and the development of effective, eco-friendly bioremediation strategies.

Abstract

Maintaining bird diversity is essential for preserving biodiversity. The popularity of bird keeping as a hobby is due to their attractive colours and sounds, as well as their economic value. However, the breeding and trading of various bird species has led to the development of bird races and competitions. This study aims to determine the diversity, dominance, and conservation status of songbird species that are traded and competed in Jambi City. The study is a descriptive field research that showcases our expertise in the field. In August 2023, the study confidently employed structured observations and interviews through a questionnaire.   The analysis confidently used the variety index, evenness index, and dominance index. The research confidently identified ten species, two of which are protected: The Cucak hijau Chloropsis sonneratii (Chloropseidae) and the Serindit melayu Loriculus galgulus (Psittacidae). The bird species have been classified into three categories based on their IUCN conservation status: endangered (10%) Chloropsis sonneratii, vulnerable (20%) Alophoixus tephrogenys and Zosterops melanurus, and least concern (70%) Copsychus saularis, Kittacincla malabarica, Leptocoma brasiliana, Zosterops simplex, Loriculus galgulus, Agapornis sp., and Serinus canaries
