Abstract

The Kaligarang River is one of the longest rivers in Semarang which is widely used for various purposes over time, this river has changed towards sedimentation and erosion. Therefore, the existence of vegetatiton is important as an ecosystem balancer. The purpose of this study is to study environmental parameters and analyze the diversity of plants found in the Kaligarang watershed. This type of research includes exploratory research with a line plot sampling method (5 quadrant plots) measuring 1x1 meters for herbs, 5x5 meters for shrubs/shrubs, and 10x10 meters for trees in May 2023-May 2024. Research locations at Tinjomoyo station, Tugu Soeharto, and behind PDAM Tirto Moedal. The results showed that the soil types found were sandy loam, clay, and dusty clay; soil pH between 5.51-6.23; C-organic content 0.32-0.94%; light intensity between 2950-7610 lux; ambient temperature 38°C-45°C, and air humidity 24%-43% which means that the quality of the environment is quite supportive of plant growth quite well. The results of the calculation of plant species diversity (H') with tree habitus was found at station 1 was 0,69 (low) and the highest at station 3 was 0.97 (low); the lowest shrub at station 2 was 0.45 (low) and the highest at station 3 was 1.19 (medium); and the lowest herbaceous at station 1 was 1.25 (medium) and the highest at station 2 was 2.92 (medium). The conclusion from these results is that environmental factors and plant diversity values at each station are different.

Abstract

Biodegradation is a physical decomposition of the substrate caused by the activity of microorganisms by producing products that have benefits for humans. Lignocellulose degrading fungi are microorganisms that play a role in the process of decomposing organic waste. The biodegradation rate of each type of lignocellulose degrading mold is different. The purpose of this research is to comprehensively analyze and compare the rate and level of biodegradation of leaf waste in lignocellulolytic molds isolated from the campus environment of Universitas Negeri Semarang, as well as to identify and evaluate the type of lignocellulolytic mold that shows the highest efficiency in the rate and level of biodegradation of leaf waste. The method used in this research is quantitative method, by measuring the mass ratio and pH of leaf waste media before inoculation and after inoculation. The results of this study are the rate of leaf waste biodegradation based on the ratio of leaf waste mass by Trichoderma koningiopsis mold isolate of 0.015 grams/day, while by Trichoderma erinaceum mold isolate of 0.002 grams/day. Then the rate of leaf waste biodegradation based on the pH change value of leaf waste by Trichoderma koningiopsis mold isolate is higher with a pH change value of 0.3 when compared to the Trichoderma erinaceum mold isolate with a pH change value of 0.1. The superior performance of Trichoderma koningiopsis highlights its potential application in optimizing organic waste decomposition systems and provides a scientific basis for selecting lignocellulolytic fungi in sustainable waste management programs.
