Abstract

Soil fungi, which produce hormones that occupy the rhizosphere ecosystem, have roles as agents to promote plant growth. This study aims to isolate rhizosphere fungi in mahogany in the Experiment Forest of Universitas Hasanuddin, and identify the fungal isolates obtained based on morphological characters. The research began with rhizosphere soil sampling, isolation, and identification based on morphological characters. The rhizosphere microbial isolation on mahogany stands in the Unhas Educational Forest obtained 18 fungal isolates with varied morphological characteristics, both in colony color and elevation. Microscopic observations resulted in 4 genera, namely Rhizopus, Gliocladium, Trichoderma, and Aspergillus. The results showed that there were superior fungi isolates that could produce growth hormones and could be applied to forest plant seeds. The formula with these select fungi can give the seeds optimal growth in forest plant seeds.

Abstract

This research aims to determine the total chlorophyll of jabon merah leaves extract using acetone and ethanol solvent and to determine the difference in total chlorophyll of jabon merah leaves extract using acetone dan ethanol solvent. The result of the analysis of chlorophyll levels in the extraction of jabon merah leaves using the SPAD-502 method showed that the base and the middle of the jabon merah leaf were the part that had the highest chlorophyll content, and the tip of the jabon merah leaf has a lower chlorophyll content. In the spectrophotometric method using acetone solvent, the result of chlorophyll a is 34.543,9 mg/L, and chlorophyll b is 30.338,6 mg/L. The result of chlorophyll using ethanol solvent is 33.171,8 mg/L for chlorophyll a and 19.065,9 mg/L for chlorophyll b. The total chlorophyll content in jabon merah leaves with acetone solvent is 65,346,4 mg/L, and for ethanol solvent, ia 52.474 mg/L. The results show that acetone is a good solvent for extracting jabon merah leaves.
