Abstract: The growth regulators of gibberellin and cytokinins are found in banana hump extract, while natural pesticides are found in the neem leaf extract.
These two active ingredients can condition the growth and yield of chilies.
There have not been any publications on the use of banana hump extracts and neem leaves to increase the growth and production of chili plants.
The writing of this research article aims to explore the diversity of Indonesia's biological resources, among others, sword stalk banana hump extract and neem leaves which can stimulate the growth and yield of red chilies.
Data analysis used a randomized block design with two variables and 3 repetitions.
The first treatment used banana hump extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five percent, and the second treatment used neem leaf extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five, percent.
A total of 600 grams of banana hump granules and neem leaves plus 1 liter of methanol, concentrated to a volume of 250 ml were used in this The data discussed included plant height, crown width, leaf area, number of fruits, main branches, wet and dry weight of fruit, wet and dry weight of roots, the incidence of diseases and pests, colony diameter of Colletotrichum capsici.
The administration of neem leaf extract had a significant effect on crown width 44 and 54 days after planting, while the leaf area had a significant interaction between 44 and 64 days after planting, the main branch had significant interaction between the ages of 54 days after planting, and the incidence of disease had a significant interaction between the ages of 44 days after planting.
The findings of the study were that the neem leaf extract had a significant effect on growth, whereas the banana hump extract did not have a significant effect on production because during the five months of the study there was a long dry season, so there was a water deficit which was a limiting factor in the production of fruit formation.

natural vegetable INTRODUCTION Background Chilli includes fruit vegetables which are additional flavoring ingredients with spicy side dishes.
Almost all people need chili sauce after it is processed from raw chili.
This condition causes the demand for chili to take place continuously.
The cultivation of chili plants often gets problems, namely the presence of aphids and pests and anthracnose diseases on chili caused by the fungus Colletotrichum capsici.
This study was different from previous studies because the factors discussed were the growth, production, and attack of aphids and anthracnose in chili plants after being given neem leaf extract and banana weevil.
Previous studies discussed giving single-factor neem leaf extracts to aphids or diseases anthracnose, and giving banana hump extract to chili production is not a combination of giving both extracts on growth, production, and attack of pests and diseases.
136 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 A decrease in chili plant production can be caused by many factors including caused by some harmful fungus, namely anthracnose disease caused by Colletotrichum capsici and other fungus chili leaf spot of Cercospora capsici, fusarium wilt of Fusarium oxysporum f.
sp capsici, cause fallopian disease of Sclerotium rolfsii (Yanti, 2.
The production of chili can be drastically reduced by these two intruding bodies, so this research is looking for alternatives in suppressing attacks through the administration of banana hump extracts and neem leaves.
The level of national chili needs to be increased from April to June 2019.
Based on the Ministry of Agriculture records, the level of national chili needs in April 2019 reached 73,999 tons, in May 75,877 tons, and in June around 77,755 tons, whereas when compared to the national average production level, the need is still relatively fulfilled.
Ismail noted, the national average chili production rate per month reached more than 100 thousand tons.
As for the details of national production recorded, in April 2019 amounted to 110,707 tons, in May 113,032 tons, while in June it reached 115,357 tons (Republika, 2.
The development of processed chili export volumes during the period of 2006-2014 has increased with an average value of 43.
55% per year.
The export quantity of Indonesian chili is always increasing from 1.
54 thousand tons in 2006 to 14.
35 thousand tons in 2015 although in 2011 it decreased to 8.
6 thousand from the year 2010 which was 8.
7 thousand tons.
While on the other hand, the development of imported chili imports during the period of 2006-2015 increased with an average value of 12.
97% per year (Yanuarti and Mudya, 2.
Tackling pests and major diseases of chili with synthetic pesticides can reduce the level of attack, but the residues hurt the environment, such as water, soil, and air.
An alternative way to overcome the residual danger is through the use of plant-based pesticides.
Plant-based fungicides are environmentally friendly so they are not harmful to humans, easily The use of vegetable pesticides is relatively inexpensive, easy to obtain, and easy to use (Suleiman, 2010.

The flowering phase of bean plants is also prone to abortion so that to prevent the loss of flowers can be applied to plant regulating substances, a type of hormone gibberellins (GA.
The hormone gibberellins can stimulate flower growth and fruit formation and strengthen the condition of the stems on bean plants.
Also, the flowering phase of the hormone gibberellins has a role in preventing the loss of flowers (Senja, 2.
This research, namely reconditioning the growth and production of red chilies by giving banana hump extract and neem leaf extract, has not found the same research from various The research articles only focus on the use of synthetic gibberellins in chili plants, and not natural gibberellins from the banana hump.
Likewise, the use of neem leaves as a natural fungicide on chili plants is only a single treatment or a combination of several natural fungicides, and not a combination of natural gibberellin growth regulators and natural fungicides, therefore this study was conducted.
Several related studies, among others, the results of research Application of synthetic GA3 treatment with 4 concentration levels, namely: 0 ppm (G.

The respective percentages of neem leaf extract and banana hump extract and the calculations are guided by first making the two extracts of the mother liquor from neem leaves and banana hump.
600 grams of neem leaf flour are added with 1 liter of methanol, also 600 grams of banana hump flour are added with 1 liter of methanol, next hen the two solutions are extracted using a rotary vacuum evaporator until a thick solution of 250 ml is formed.
The percentage concentration of neem leaf extract and the percentage concentration of banana hump extract did not affect the increase in height of chili 145 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 Neem leaf extract has a significant effect on crown width but does not occur in banana weevil extract.
The administration of neem leaf extracts and banana weevils had a significant interaction effect on the leaf area at 44 days after planting.
The administration of neem and banana weevil extracts had a significant interaction effect on the main branches at 54 days after The administration of neem and banana weevil extracts had a significant interaction effect on disease incidence in chilies at 44 days after planting.
Some of the previous literature that supports the results of this study can be described in the following statement.
The application of liquid organic fertilizer in kapok banana hump concentration 10%, 20%, 30% does not affect the height of stems of okra plants (Wea, 2.
The different results of the study were that the doses of banana hump consisting of 0, 10, 20, 30 grams/polybags had an impact on the increase in leaf length, the number of leaves, root weight, fresh weight, and dry weight of oil palm seedlings in the pre-nursery.
The dose of 20 grams/polybag stimulated the increase in leaf length of oil palm seedlings in the pre-nursery compared without treatment, as well as for variables of leaf number, root weight, fresh weight, and plant dry weight (Sitinjak, 2.
Giving 0%, 15%, 30%, 45% concentration from neem leaf extraction and banana hump extraction can increase plant crown increment at the age of 44 days, and 54 days after planting, while at the age of 14 days, 24 days, 34 days, and 64 days after planting did not increase the crown of the plant.
Giving a combination concentration of 0%, 15%, 30%, 45% of neem leaf extraction and banana hump extraction, was able to increase leaf area at 44 days and 64 days after planting, but there was no increase in leaf area at 14 days.
24, days, 34, days, 54 days after Giving a single concentration of 0%, 15%, 30%, 45% of neem leaf extraction and banana hump extraction, was not able to increase the number of fruit, wet fruit weight, dry fruit weight, wet and dry weight of shoots, and roots for all ages of observation.
from 14, 24, 34, 44, 54, 64 days after planting.
This is because the extraction of banana humps containing natural growth regulators, namely: gibberellin 132.

ource from the testing laboratory of PT Biodiversitas Bioteknologi Indonesia Tahun 2019.
Based on this laboratory analysis, it is felt that it is necessary to provide a growth regulator for banana hump extraction more than three times or to increase the concentration of growth regulator substance for banana hump extraction.
Giving a 45% solution concentration derived from the fermentation of local microorganisms of banana hump could increase the variables of plant height, number of leaves, number of productive branches, and fruit weight per plant compared to the control but did not affect the concentration of 30% (Azizy et al.

The results showed that the fermentation treatment of three banana hump varieties had an effect on the variable of stem diameter, number of leaves, crown width, and fruit length, but did not affect the number of fruits, fruit weight, fruit diameter, and weight of chili plants (Tobing et al.

CONCLUSIONS
Growth and production can be reconditioned through the application of banana weevil extracts and neem leaves which can be seen from a significant contribution to the growth of several variables, as well as the potential to increase chili production when water is available for plants.
Gibberellins and cytokinins did not affect the growth components of the variables of plant height, stem diameter, and canopy width, at 14, 24, 34, 44, 54, 64 days after planting, but the combination of gibberellin, cytokinins, and natural compounds of neem leaf extract affected leaf area at the age of 44 days, and 64 days after transplanting.
Gibberellins and cytokinins did not affect the production components of the variables of fruit number, wet weight and dry weight of fruit, wet weight and dry weight of roots and canopy, but the combination of gibberellin and cytokinins affected the number of branches at 54 days after transplanting.
The combination of growth regulators from gibberellin, kinetin, and natural compounds from neem leaf extracts had an effect on disease incidence at the age of the plant 44 days after Gibberellins and cytokinins and natural compounds from neem leaf extract did not affect the incidence of pests.
The combination of gibberellin, cytokinins, and natural compounds from neem leaf extract also did not affect disease incidence.
The growth and production of chili plants are influenced by climatic factors during the study, were at the time of the research there was a long dry season.
Climatic factors that are not by the requirements for plant growth and production, namely: average humidity, too low average rainfall so that there is less water for the process of plan photosynthesis and plant metabolism which has an impact on the fruit formation process, the average sunshine intensity is less which also affects the photosynthesis process so that fruit formation and plant growth will be disrupted.
Banana weevil and neem leaves that will be used as extracts should not be dried in the oven, but drying should be done naturally in the morning sun so that there is no evaporation of active ingredients .
rowth regulators and pesticide.
Planting chilies preferably in wet months, because water is the main component of weight building and other organs.
