The result of this activity were the farmer group be able to cultivate indigofera, built 2 water shelter to drainage indigo plant. The result of seedlings is not satisfied yet because the growth of sprouts were not simultaneously and not applying hormone gibrelin technology so that for next step need revision in raise seeding. The farmer group ca easily their indigofera to make paste for batik dye color

This plant is easy to be cultivated and can grow well up to a height of 1200 m above sea level, easy produces seeds so it is easy to be propagated, resistant to drought, has deep roots and can maintain fertility so it is suitable for land conservation, quick harvested since planting only 3 months (Morip et al., 2020). To supply qualified seeds, science and technology (IPTEK) are needed to produce good quality indigofera.
Traditional planting is very minimal production inputs, for example with improvised soil management, local seedlings, planting techniques to follow its predecessors, the use of improvised fertilizers and even without fertilization, maintenance is not serious, of course this must be abandoned and must be changed towards modern who are able to compete in producing quality and quantity in terms of harvest value (Muzayyinah, 2014

METHODS
Partner's problem is fail to obtain qualified crop production due to lack of capital and knowledge. Farmer groups need help from business equipment and assistance to raise the spirit of indigofera cultivation. Ex-bent land area in 9400 m2 which has potential to be planted has not been used optimally for production of qualified indigofera.

Training to Plant Indigo Seeds
The training invited 20 group members. The training instructor is the father. Krispinus KP is one of the service team personnel. The method uses the technology of adding the hormone gribelin.
The trick, seeds wrapped in water-soaked p-ISSN : 2548-8783 e-ISSN : 2548-8791 gauze and hormones, wait for up to 3 days and should not be exposed to sunlight, after germination is treated until the age of 6 weeks with a height of approximately 25-30 cm (Rosadi et al., 2018).

Training in making manure
Plans to invite cattle and goat farmers.
The trick is the material needed to make compost from cow dung, which is cow dung at least 80-83% and is better when mixed with urine (Sindhu et al., 2016).

Planting of Indigofera Seeds
Simply  The composition of manure and NPK fertilizer is 30: 1 or can be up to 50: 1 which must be more manure (Sindhu et al., 2016).
So that the results are more optimal, it can make bokashi or ferment the fertilizer first.
This will make fertilizer nutrients absorbed quickly by plants, by using EM4 to make this bokashi.
