“…The results of previous research by Rahardjo [6] showed that ekinase can adapt in the tropics in which the altitude range is 400-1200 meters above sea level (masl). Echinacea purpurea grows well in loose moor soil, good aeration and drainage, with a soil pH range between 5.5 -7.5, and a high level of organic matter [7].…”

Purple Cone Flower (Echinacea purpurea) is one of the introduced medicinal plants originating from America which has its native habitat growing in subtropical countries with optimal growth conditions of low temperature and full sun exposure. Problems that occur in climate change between subtropics and tropics, especially in Indonesia will have an impact on the less than optimal growth and development of plants so that it will reduce the production and quality of ekinase yields. One way to improve ekinase can suitable in Indonesia (especially in the lowlands) is by adding biochar as a soil enhancer and hormones. The aims to study the interaction between the addition of biochar and the level of hormone dose on the growth rate of ekinase. The research method used a Split-Plot Completely Randomized Block Design. The results show the interaction between the type of biochar and hormone dose. The best results were shown in the treatment of giving husk charcoal and 6 ml/L hormones of 27.67 cm for plant height and 89.67 cm2 for leaf area. The formation of the highest number of leaves was 26 in the treatment of husk charcoal and hormone 2 ml/L. The best results were wood charcoal and hormone treatment 6 ml/L of 0.1467 for the rate of photosynthesis and 0.02937 for the rate of transpiration. Treatment with a dose of 6 ml/L hormone can optimize the growth rate of ekinase.

“…Indonesia was the first country to introduce E. purpurea as a medicinal herb. Rahardjo (2000) and Rahardjo et al (2001) conducted preliminary research in Indonesia on the cultivation potential and adaptability of E. purpurea in tropical environments. Echinacea purpurea can thrive in both the highlands and the lowlands of the tropics (Rahardjo 2005).…”

Abstract. Cahyaningsih AP, Etikawati N, Yunus A. 2022. Morphological characters variation of Indonesian accession Echinacea purpurea in response to gamma-ray irradiation. Biodiversitas 23: 5351-5359. Indonesia was one of the countries that introduced E. purpurea as a medicinal plant. Accessions of E. purpurea that have been successfully cultivated in Indonesia have narrow genetic diversity, lack accession variation, and have almost uniform tillers. This study was conducted to determine the effect of different doses of gamma-ray irradiation on morphological characteristics of E. purpurea accession B2P2TOOT. The experimental design was a Randomized Block Design with three replications, and six doses of gamma-ray irradiation (0, 15 Gy, 20 Gy, 25 Gy, 40 Gy, and 60 Gy) were used. The qualitative morphological data were presented descriptively; quantitative data were analyzed using ANOVA followed by a DMRT test at a 5% level with SPSS 16.0 application. The Dice similarity algorithm analyzed the similarity index, group analysis, and dendrogram construction using the UPGMA method with the NTSYS 2.02 application. Gamma-ray irradiation treatment increased the survival rate of E. purpurea plants grown in tropical lowlands. A dose of 15-60 Gy gamma irradiation did not affect the qualitative morphology of E. purpurea roots, stems, and leaves. Irradiation at doses of 40 Gy and 60 Gy resulted in flowers with more variation in color, overall flower shape, and arrangement of ray floret. Gamma irradiation significantly affected plant height, leaf length, leaf area, flower angle, and the first day of flowering. The 40 and 60 Gy doses resulted in longer leaves with wider leaf surfaces. The dendrogram revealed that E. purpurea irradiation resulted in two main groups, with doses of 40 and 60 Gy forming their groups and increasing morphological variation by 30% compared to controls.

Forest protection and development are essential because forests are the world's lungs. In addition, the HTI organization (modern manor backwoods) began to hide again. However, due to the great interest in wood to be used as raw material for material and property production lines, large organizations started to develop hamlet wood which was then marketed abroad, such as pressed wood, rattan, sawn timber, and done jobs for individuals in the area around the hamlet. By making a prediction, knowledge about the growth of forest plants can be known so that they can anticipate or minimize the risks that may arise. They can assist in determining policies and making decisions. This study aims to predict the growth of forest plants in the following year using an Artificial Neural Network Algorithm. The information used in this study is from the Central Bureau of Statistics from 2011 to 2022. The method of implementing this research uses the Fletcher-Reeves Algorithm, one of the Artificial Neural Network methods using 5 models, including 7-10-1, 7-15- 1, 7-20-1, 7-25-1, and 7-30-1. Of the five models, the structural model is 7-20-1 with an MSE value of 0.00037397. It can be said that this model can be used because it produces a fast combination and a short period of time.
