ANALISA KANDUNGAN EKSTRAKTIF KAYU KELAPA (Cocus nucifera Linn) BERDASARKAN UMUR DAN LETAK KETINGGIAN PADA BATANG
Abstract: This study aims to
determine the content of extractive substances based on age andlocation heights
on the stem. The introduction of the nature and chemical compositionof wood is
one of the basic assessment of the use of wood. By knowing the content of
extractive substances based on age and height location on the trunk. Be
expected coconut wood, forest products are expected information technology
allows the oil industry serve as a nutrient such as sawn boards, cement board
and furniture. Based on the function of extractive substances eksraktif divided
into primary and secondary extraction. Substance is primary extractive extractive
substances dissolved in cold water
extraction and hot water, extractive content in this group are seen at the end.
Extractive dissolved in cold water extraction on the tree with the age of 30
years old ± 3.1% and the tree age of 40 years old ± 1.87%. Extraction using hot
water extractive content in the tree with the age of 30 years ± extractive
content on bigger tip to the treatment of other parts of the value of
extractive content of 28.27%, while the 40 years old tree extractive content of
11.67%. The value of content in the primary extraction is caused by a function
of extraction is used by plants for growth while other types of extraction is
estimated as dissolved mineral, salts, sucrose, polysaccharides, starch, gum,
soluble carbohydrates, proteins and vitamins. The big difference in the content
of the primary extraction of water extraction due to cold and hot water at
ambient conditions extractive was dissolved in cold water extractives that have
low molecular weight and a bit of dye, while the hot water to an increase in
temperature accelerates the reaction and all the soluble extractive in cold
water will be dissolved in hot water extraction. The amount of extractive
properties will provide a more durable high when thesesubstances are toxic extractive
and will cause damage to the timber if the content ofextractives contained in
wood is the favored extractive substances of insects.
