Abstract

Polyscias scutellaria can be planted as hedge plants at home. This plant has many advantages, one of which is a hair tonic that already has a patent number. To be used on an industrial scale, it is necessary to provide raw materials on a large scale, which can be done by planting in certain regions. The objective is that the empowerment of the PKK in Pasirwangi District, Garut will make the Pasirwangi sub-district one of the centers for producing P. scutellaria leaf raw materials. The activities carried out include educating on the use of medicinal plants, especially P. scutellaria and ginger, practicing training on planting techniques, cultivating them, and giving P. scutellaria cuttings and post-harvest processing techniques. This activity is an activity of the IPB Lecturer Homecoming Program in 2022 which is carried out in several stages. Evaluation and monitoring of cultivation executed two months after training. The evaluation results showed that there was an increase in knowledge related to the cultivation of P. scutellaria and participants cultivated P. scutellaria in their garden after the training was more than 90%. All of the participant’s responses to the training carried out stated that it was very useful and hoped that the activities would be sustainable.

Abstract

Adenostemma lavenia (Asteraceae) is a medicinal plant considered a weed, consisted a lot of secondary metabolites, including phenolic and flavonoid. This species has been widely distributed in various countries but has yet to be widely cultivated. Thus, this study aimed to determine the highest plant growth, phenolic, and flavonoid production from A. lavenia cultivated under different shade of nitrogen fertilizers. The experiment used a nested design consisting of 2 factors. The first factor was shade with different intensities (0, 25, 50, and 75%) and the second was nitrogen fertilizer with different doses (0, 45, and 90 kg/ha). The highest plant was achieved at 50% shade level, while the highest leaf number and branch were 25% and 0%, respectively. Leaf thickness and stomata number increased in no-shade conditions. The production of phenolics and flavonoids was high under shaded conditions, supported by significantly high phenolics and flavonoid total under shade conditions, i.e., 35.94 mol gallic acid equivalent/plant and 21.76 mol quercetin equivalent/plant, respectively. A 90 kg/ha nitrogen fertilizer dose produced the best plant growth, phenolic, and flavonoid production. Keywords: Asteraceae, Heatmap, Nested design, Shade.
