| Abstrak/Abstract |
Aren plant (Arenga pinnata) can produce industrial raw materials. Almost all parts
of palm trees can be utilized, namely young and old leaves, young endosperms, stems, stem
bunches of flowers, roots, and fibers. Sugar leaves used for the roof of the house or hut.
Young endosperms are used for fleas as a mixture of food or drink. Stem aren tree can be
taken flour for the manufacture of palm flour. The main problem is the unclear growth of
aren trees caused by soil characteristics in various places. The objectives of the study were
to: 1) understanding the effect of land characteristic on the growth of aren trees; 2) look for
various growth characters of aren plants at different altitudes. The study was conducted by
survey and observation. Location was selected by purposive sampling, i.e. areas with altitude
(<600 m ASL, 600 to 700 m ASL, and> 700 m ASL). The results showed differences results.
Aren plant cultivation techniques that include the way of nursery, maintenance and post
harvest management not implemented in Kulonprogo region, especially Ngargosari village,
Pagerharjo, and Nglinggo. There is influence of altitude factors of place, soil type,
morphology, physiology, and biochemistry to growth and aren products.
