Study Content Nutrient Waste Plant Seeds Nyamplung (Calophyllum inophyllum Linn) after Made as Biofuel

Abstract

Determination  revoke  government  fuel  subsidies  in 2008, with all its  consequences have begun to be realized by finding various solutions techno-socio-economic development.  Among  the  various solutions that are developing  alternative  fuel  made from vegetable oils or biofuels. This is demonstrated by the issuance of  Presidential Regulation  No. 5/2006  on  National Energy Policy and  Presidential Instruction  No. 1/2006  on the Provision  and Use of  Biofuels  (Biofuel)  as  an  alternative fuel on January 25, 2006.  Biofuel Excess addition can also be environmentally friendly renewable, biodegradable, able to eliminate  the greenhouse  effect, and continuity is assured  raw  material.  Bioenergy  can  be  obtained with a fairly  simple  way is through the  cultivation  of  biofuel  crops,  have  recently  discovered a new source of biofuel that is  nyamplung (Calophyllum  inophyllum Linn).  Nyamplung is a plant that grows in coastal forests.

As  with  other  agricultural  residual  waste,  waste  from the  process  of  making  biofuels from  plants  also  contain  nutrients  that can be used as a soil or as a source  of  fertilizer for  plants.  This  study  aims  to  assess  the  nutrient  content  of  the  waste  content  of seeds nyamplung (Calopphyllum inophyllum Linn) after it is created as a Biofuel.

The  results  showed that the biofuel seed crop nyamplung (Calopphyllum inophyllum Linn)  have  oil  content  of  46.57%,  and  biofuels  from  waste  plant  seeds  contain nutrients:  total N 1.43%  (very  high),  47.99%  Organic  C ( very  high),  total P 0.35% (very  low),  1.30%  total  K (very  low),  C / N  33.78 (very  high),  and 17.93  KPK  to 100 g-1 (medium).

Key  words: oil  nyamplung, nutrient  waste  plant  seeds  nyamplung
