INTRODUCTION
Physalis angulata L. is one of the Solanaceae family in Indonesia known as "ciplukan" which has the potential as a medicinal ingredient because it acts as an immunomodulator and antioxidant.Ciplukan extract contains total phenols between (0.46-0.51) g -1 and antioxidant activity from 1575 mg.g -1 to 4311 mg.g -1 BHA (Kusumaningtyas et al., 2015).Antioxidant activity was positively correlated with phenol content.Phenol is an essential plant constituent because of its ability to scavenge free radicals due to its hydroxyl group (Tien et al., 2021;Anh et al., 2018).The leaves contain saponins, chlorogenic and flavonoids.The fruit of P. anggulata contains phenol, physalin, tannins, cryptoxanthin, ascorbic acid and sugar, while the seeds contain palmitic and stearic acid.The roots contain alkaloids and chlorogenic acids (Jaroslava et al., 2018;Pillai et al., 2022;Zhan et al., 2018).These chemical components are important for treating various diseases such as schistosomiasis, trypanosomiasis, inflammation, malaria, leishmania, asthma and tuberculosis (Abdul-Nasir-Deen et al., 2020;Oliveira et al., 2020).
Ciplukan is an annual herbaceous plant with a genus of 120 species (Iwansyah et al., 2022).The species commonly found is Physalis angulata L., native to Brazil and grows wild in all countries.This plant is cultivated commercially in southern Brazil, namely in Rio Grande do Sul ( Leite et al., 2021;Figueiredo et al., 2020;Ramos et al., 2021).Ciplukan plants are widely distributed worldwide, namely in tropical and subtropical areas.However, ciplukan in Indonesia is a weed that is rarely cultivated.Ciplukan grows wild with a height of approximately 0.5-1.0meters.This plant thrives in the lowlands to an altitude of 1,550 meters above sea level, spread over dry land and can be found in teak forests (Pinto et al., 2016).The flowers of P. angulata are yellow and the fruit is protected by a hood or petal called the calyx.Genetic and environmental factors or growing locations influence chemical compounds and pharmacological activities in plants (Vieceli et al., 2021).So that efforts are needed to domesticate ciplukan in Indonesia.
Plant domestication is an evolutionary process mediated by manufactured selection and evolutionary forces in plant populations (Montero et al., 2021).Domestication supports compatibility in cultivated plants through changes in their survival, reproductive strategies and several reproductive parameters associated with domestication (McKerrow et al., 2021).The treatment of plant spacing and chicken manure and chemical fertilizers in the domestication of P. angulata shows that the wider the spacing, which is 40  60 cm, can increase the number and weight of fruit Vegetation Analysis and the Role of Growing Media on the Growth and Yield of Physalis angulata L. in Domestication planted by up to 463-843% (Zawani and Nikmatullah, 2021).Domestication with organic chicken fertilizer and a dose of 0.2 g/polybag produced the highest leaf growth and plant biomass (Indriani et al., 2022).The chemical fertilizer type composition of 20 tons/ha and 60 kg/ha of cow manure produced the highest number of fruit and fruit weights in P. angulata domestication (Oliveira et al., 2023).There are no differences in morphology and physiology between P. angulata plants that grow wild and those that have been domesticated (Goecke et al., 2020).Differences in the location do not show the morphological and physiological characteristics of the plant and if cultivated can have a production per hectare of 11-14 and up to 28 t ha -1 .Variations in vegetative and fruit traits show a broad genetic basis in P. angulata (Saavedra et al., 2019).Domestication is also an effort to conserve biodiversity, emphasizing the potential long-term evolutionary consequences of species loss.
Several recent studies warn of potential ecosystem disturbances due to species loss (Lazzaro et al., 2020).This study examines the analysis of vegetation in the ciplukan growth environment and the role of growing media in domestication efforts on ciplukan growth and yield.
Domestication was carried out from June 2021 to August 2021 in the greenhouse of the Experimental Laboratory of the Faculty of Agriculture, Sebelas Maret University, Sukosari Village, Jumantono, Karanganyar, Central Java with an altitude of 196 meters above sea level and coordinates 7378S and 1005652E.This study used a survey method, the survey location was selected using a purposive random sampling method.The determination of the sample plots and the vegetation analysis used was the transect method.Transect lines were made of observation plots of 20  20 meters (tree vegetation), 5  5 meters (herbs/shrub vegetation) and 1  1 meter (grass vegetation).The variables observed were: plant density, relative density, frequency, refative frequency, dominance, relative dominance, important value index, distribution pattern and diversity index.Vegetation analysis data was carried out descriptively.
The design used in domestication was a completely randomized design with 1 factor, namely planting media in five treatments and 5 replications.Planting media factors with a ratio of 1:1 are: soil without mixture, soil + goat manure, soil + vermicompost, soil + husk, soil + husk charcoal.Plants were planted using polybags with growing media according to the treatment.Variables observed in domestication were: plant height, number of leaves, root length, number of flowers, number of plants, fruit weight, plant fresh weight, plant biomass.Harvesting is done after the ciplukan is 6 weeks after planting.Vegetation data with descriptive analysis and domestication data were analyzed using analysis of variance with a level of 5% if significant further testing with 5% DMRT.

Vegetation analysis of ciplukan original habitat
Vegetation analysis is a method used to determine the distribution of various species in a habitat (Munroe et al., 2021).Short non-woody plants are called grasses.Grass is often found as ground cover vegetation.The results of the analysis of grass vegetation at the research site showed that the highest relative density value was found in creeping grass (Festuca rubra) with a value of 30.496% so that this grass was found more often than other types of grass.Wudelan grass (Cyperus kyllinga) has the lowest relative density value of all grass vegetation, namely 0.709% (Table 1).The highest relative frequency was found in grintingan (Cynodon dactylon) with a value of 26.667% while other types of grass had the same value of 6.667%.The distribution of grintingan (Cynodon dactylon) is wider than other grass types.
The results in Table 1 show that the distribution pattern of all species is uniform except for the creeping grass (Festuca rubra), which is clustered.Creeping grass is clustered because it has a V/M value >1 while other species are uniform because the V/M value is <1.A uniform distribution pattern can be produced from high or low frequency values as well as a clustered distribution pattern.The value of the diversity of grass vegetation at the research site is moderate because it has a total h value of 1,994.The amount of diversity (H') is said to be moderate if the total value is 1H3.This analysis aims to determine which herbaceous plants or shrubs have a high ability to play a role in an environment or community.The herbaceous vegetation or shrubs at the study site contained 25 plant species.The results of the analysis obtained were the highest relative density of sidaguri (Sida acuta) with a value of 17.226% so that this plant was found more often than other types.The smallest value was found in sawdust (Serratula tinctoria) and kesum (Persicaria odorata) with the same value of 0.224%.The highest relative frequency was found in ciplukan (Physalis angulata) which was 14.286% (Table 2).
Trees are included in plant vegetation other than grass, herbs and shrubs.Trees are plants whose trunks are woody and grow large.The results of Table 3 value density and the highest relative dominance of tree vegetation are owned by teak, namely 42.553% and 79.84%, respectively.Tree vegetation is a large group because it has a larger size than grass, herbs and shrubs.Teak is categorized in groups because the results of the calculation of V/M>1 are 2.432.The tree vegetation diversity index is included in the medium category because it has a value of 1,929 (1H3).Density is Vegetation Analysis and the Role of Growing Media on the Growth and Yield of Physalis angulata L. in Domestication the number of each individual in the species present in the sample plot.Relative density describes the number of individuals of each species found in the plot (Pujiasmanto and Rumia Manurung, 2022).A high relative density value can be interpreted as the number of individuals of each species found in the research location and vice versa.While the frequency is the number of occurrences of each species in the plots that have been made.The relative frequency describes the size of the distribution of a species.The larger the value, the wider the species distribution and vice versa.
Dominance serves to determine how much influence species have with each other in an ecosystem.The plant     area and plot area affected the relative dominance value (W inter et al., 2018).The significance index of a species describes the role of a species in its environment.The greater the important value index according to Nesbitt et al (2019) means that the plant has an important role in an ecosystem (Nesbitt et al., 2019).The value of the diversity of herbaceous vegetation or shrubs at the study site is high because it has a total H value of 3.931.The diversity of H' is said to be high if the total value of H'>3.Species diversity is one of the factors to state the community structure (Rhif et al., 2021).The value of H' also describes community stability, namely the community's ability to protect itself remains stable even though there are disturbances in its components (Zhou et al., 2020).

Domestication of ciplukan
The temperature in the greenhouse is 34-38 C. Light intensity 12930-15700 lux.Soil belongs to the type of alfisol.The soil is acidic because the pH value is 5.29 (pH 6.5) and the moisture content is 10.1%.The C-organic value of this soil is 2.25% and organic matter is 3.92%.Organic matter has a role in increasing the availability of nutrients, fertility and increasing the population of soil microorganisms (Vuković et al., 2021).The results showed that the planting medium had an effect on the height and number of leaves of ciplukan plants (Table 4).The lowest height with a value of 14.84 cm in the soil media treatment.This shows that ciplukan can grow with soil media without fertilizer.However, with the addition of organic vermicompost fertilizer, the highest plant yield was 27.80 cm.The lowest number of leaves was found in the soil media and soil + husk media.W hile soil treatment + vermicompost fertilizer showed the highest number of leaves, which was 158 strands.This is because vermicompost can improve soil structure and stabilize soil aeration.Worm fertillizer contains nutrients (N, P, K and Ca) and Azotobacter sp (N-fixing bacteria) which can help plant growth.If the nutrients are sufficient, the plant growth will be faster (Mahmud et al., 2018).
The results showed that the planting medium affected the number of flowers, fruit and fruit weight (Table 5).The highest average number of flowers and fruits was found in the treatment of soil planting media: vermicompost, namely 26 flowers and 55 fruits.Based on the results of the study, the number of flowers and the number of fruit in the soil treatment was not significantly different from that of soil: husk and soil: husk charcoal.The lowest fruit weight was 2.788 g in soil planting media treatment and the highest fruit weight was 58.122 g in soil media treatment: vermicompost.Plants that have a small number of fruit, the volume and weight of the fruit per unit are greater.
Planting media had a significant effect on root length (Table 6).The longest root length was found in the soil treatment: husk charcoal, which was 23.36 cm.Husk Vegetation Analysis and the Role of Growing Media on the Growth and Yield of Physalis angulata L. in Domestication charcoal acts as an organic material to fertilize the soil.While the soil treatment: husks showed the shortest root length, which was 14.4 cm.The cause of the increase in root length according to Ardiansyah (2017) occurs because the roots try to reach deeper places to find water sources.The results showed that the growing media had an effect on fresh weight and plant biomass (Table 6).Soil media showed the lowest fresh weight and biomass, namely 10.28 g and 1.05 g.Meanwhile, fresh weight and high biomass in soil: vermicompost were 183.4 g and 19,094 g, respectively.This is due to the availability of nutrients that play a role in the biomass of a plant.Sufficient nutrients will increase the biomass of a plant.
The results of the study that the ciplukan plant which has been growing wild so far can be domesticated as a cultivated plant.This needs to be done considering that this plant has the potential as a medicinal plant, so its existence needs to be protected and its production increased as pharmaceutical raw material (Purugganan, 2019).Domestication is the adoption of plants and animals from wild life into the environment of human daily life (Tomar et al., 2021).Domesticated plants will experience changes in both their shape and character.The domestication process is to tame biota to human condition with its needs and capacities (Farooq et al., 2021).The growing environment is an important factor because it is related to plant growth and production.Domestication was carried out in this study by using a variety of growing media.Planting media has an effect on the growth of ciplukan leaves.Based on the results of the study showed that soil:vermicompost media was able to encourage growth and yield of ciplukan.This is because vermicompost contains nutrients N, P, K, Ca, Mg, S, Fe, Mn, Al, Na, Cu, Zn, Co and Mo so that vermicompost can improve soil structure and stabilize soil aeration (Hu et al., 2021).Vermicompost contains nutrients (N, P, K and Ca) and Azotobacter sp (N-fixing bacteria) which can help plant growth.If the nutrients are sufficient, the plant growth will be faster.Element N is one of the content contained in vermicompost.The benefits of element N are to encourage the development of stems, leaves and vegetative growth of plants (Srivastava et al., 2020).
The results showed that soil treatment: vermicompost produced the highest number of fruits and fruit weight.While the lowest number of ciplukan fruit was found in the treatment of soil and soil: husk, which was 7 pieces.The number of fruits is affected by the leaves and flowers.The leaves will carry out the process of photosynthesis where the more leaves, the more photosynthetic results (Morales et al., 2020).The results of this photosynthesis will be distributed to help the process of forming flowers and fruit.The heaps of plant photosynthesis are stored in fruit and efforts to optimize photosynthetic results require organic materials and sufficient water for plants (Karmegam et al., 2021).The soil media treatment caused the lowest fruit weight to be 2,788 gr.The decrease in fruit size with the number of fruits was caused by insufficient photosynthesis to increase fruit size (Li et al., 2018).While the soil treatment: vermicompost had the highest fruit weight, which was 58,122 gr.Vermicompost has a high organic C content and that increasing microorganisms is the soil formed with worm droppings.Increased soil fertility makes plant growth and yields better (Blouin et al., 2019).
Soil media: vermicompost also showed the highest wet weight supported by the nutrient content of vermicompost.The availability of nutrients plays a role in the biomass of a plant.Sufficient nutrients will increase the biomass of a plant.The application of organic fertilizers increases the available nutrients, the nutrients absorbed by plants affect the growth of wider leaves (high photosynthesis) (Yatoo et al., 2021).The results of photosynthesis are used for the development of stem cells, leaves and roots (Jannoura et al., 2014).

CONCLUSION
Based on the vegetation analysis that there are 12 grass vegetation with an important value index of 71.270% in Cynodon dactylon grass.W hile the analysis of herbal vegetation contained 25 vegetation with the highest relative frequency found in ciplukan (Physalis angulata) which was 14.286% and tree vegetation analysis contained 12 trees with the highest density being teak, which was 42.553%.Ciplukan which have been growing wild so far can be domesticated as cultivated plants.The results of domestication with planting media treatment that soil media+vermicompost can encourage growth and yield of ciplukan.
