Abstract

This research is a type of comparative research using a quantitative approach. The study population was the population of Bandotan plants in the Kudus and Jepara regions. The organ parts taken from the plant were leaves, while the stems, roots and flowers were not extracted in this study. The extraction method used maceration and soxhletation with 96% ethanol solvent. Furthermore, to determine the total flavonoid content of Ageratum conyzoides leaf extraction results using the UV Vis Spectrophotometric method, it is known that Ageratum conyzoides leaf extract using the Soxhletation method has a higher total flavonoid content (0.32% b/v) compared to the Maceration method (0.22% b/v). The results of the total flavonoid test were then analyzed using the Mann Whitney U Test. Based on the Mann Whitney U Test shows that the value of Asymp. Sig. (2- tailed) of 0.102 > 0.05. Therefore, it can be concluded that there is no significant difference between maceration and soxhletation extraction methods on total flavonoids of Ageratum conyzoides extract.

Abstract

Indonesia is one of the countries that has the highest level of biodiversity in the world. However, there are still many plants in Indonesia whose species have not been identified. This causes the need to identify and classify plants. This research aims to identify the diversity and dominance of plant species from the Asteraceae family in Kawak Village, Batealit District, Jepara Regency. This study was carried out on May 28, 2023 and June 1, 2023. The method used was the exploration method by determining sampling locations at 21 points from 3 hamlets in Kawak village. The tools and materials needed for this research include an accurate altimeter version 2.3.2, ziplock plastick, newsprint, cellphone camera, meter and internet access. There are 6 plant species from the Asteraceae family, including Wedelia trilobata, Crassocephalum crepidioides, Elephantopus scaber, Chromolaena odorata, Synedrella nodiflora, and Ageratum conyzoides. The plants obtained were collected using the herbarium method. The dominant plant species from the Asteraceae family in Kawak village is tapak Liman (Elephantopus scaber).
