INTRODUCTION
The angsana plant (peterocarpus indikus) is a species that we always use to do business, usually this type of species is also considered very common in everyday life.
According to (Dwiyani, 2013) the most common tree planting as a shadera tree is the Pterocarpus indikus, based on data from the Padang City Land Sanitation and Capacity Building Service, one of the most planted trees in the city of Padang is the According to (Taskwati, 2011 andYudha et al. 2013) in Angsana, there are often other plants that live on them such as Angrek plants that live on other plants and do not take nutrients or water from the plants they live on.
Pterocarpus indicus, known as good light, produces high-quality flowers, which are used in structural work as well as for good furniture, Angsana tree can be planted as a species of agroforestry, reforestation, as a budget tree.

METHODOLOGY
This research was conducted at East Timor Coffee Institute-ETCI, from September 2023 to Fevruary 2024.The materials used were Sedling of angsana, top soil, Polibag, Book, Bulpen, Camera, Laptop, Sheet for writer, Sand, water and bucket.
This study employed a Completely Randomized Design (CRD) consisting of 1 factor with 4 treatment levels and 3 replications as follows: Factor I is the concentration of Media Composition with 4 concentration levels, namely: • M0:Control (no media composition) • M1:media composition 100 grams/polybag • M2:media composition 200 grams/polybag • M3:media composition 300 grams/polybag The concentration of media composition applied only once for a polibag.The treatment is repeated three times, resulting in 36 experimental units.
Linear model: Yijk = u + ri + εij + δijk (Gaspers, 1995).Where: • Yijk = Observation value k in experimental unit j receiving treatment i µ = Overall mean value (population mean) • ri = Effect of treatment i • εij = Error effect on observation k in experimental unit j receiving treatment i • δijk = Error effect on observation k in experimental unit j receiving treatment i.

DISCUSSION
Observation of the length of the plant, for treatment with less control in each unit with a value of (A0) of 19.33cm which has no significant influence on the treatment of each unit.In addition to treatment (A1) 10 Treatment by (A3) 100.33cm and (A3) 40.33cm significantly influenced treatment (A0) 19.33cm. of treatment A1, A3 and A2 showed that the influence of organic or animal waste intake on the supply of organic or animal waste has a significant impact on the plants of Angsana (Pterocarpus indicus) increased in length or height in each unit as stated by the researcher, Nasahi, 2010.That the method that absorbs soil quality is the use of local organic adubu resources or animal waste through the supply of organic adubu contributes to the growth of an angsana plant (Pterocarpus indicus) water quality in its large amount, increasing the height of the plant and also increasing the amount, green and growing through the process of photosynthesis.
The result is shown by the diameter of the Angsana tree (Pterocarpus indicus) per unit with treatment, the volume of the different crops.But there is the same relative majority diameter.Treatment (A0) 1.73cm is controlled by unit I until 3 units are less visible in each unit.For treatment (A2) 2.07cm and (A3) 2.82cm influence the treatment of A0, the relative diameter of the plant is stable, re-ligated to the treatment (A1) 2.27cm influence all treatment in each unit which is why one of the experts named, Lingga, 2006 It is highlighted that organic adubu or animal waste is a cold adubu that makes changes to soil mineralogy by offering directly to plants.Organic adubu plays a very important role in improving soil nutrition through soil bacteria.The researcher further reinforced that organic breastfeeding has a good influence on the development of Angsana plants (Pterocarpus indicus) for the allocation of each unit.
In the results of the Angsana (Pterocarpus indicus) plant observation, the control part (A0.Among both (A1) 14.33th and (A2) 1xth have a more significant influence on the treatment of A0 and A3.Organic Adubu has a more significant influence on the growth of Angsana (Pterocarpus indicus) in each unit increased to a greater extent and organic adubu or animal waste increases or increases soil density and reduces soil volume to provide mineralogy for plant growth.

CONCLUSSION AND RECOMENDATION
Based on the findings above, the influence of organic breastfeeding supply on the development of Angsana plants (Pterocarpus indicus) and irritability in A3 treatment has a significant and significant effect such as plant length, diameter and quantity of life.
