Abstract

The purpose of this research is to study the effect of fractional diatillation of cananga flower from Boyolalion the ester number and the oil properties. The properties were then evalw;ited based on the Ifido1U.1Bian Industrial Starrdard requirement for  cananga oil.  The fint  (ractiOn was obtained during the fint  0 -   6 houn  distilling time,  the second fraction was from 6 -   10 houn,  and third fraction '(rOm  11 -   15 hours."  .The raulta showed that the ester number of oil ('r(lctiom and the refractive index of the second and third fractions have met  with the 1ndonesian Industrial Standard requirement. The speci(ie gravity of oil fractions, hOwever, have not met  with  that standa~           'ester number of  the fint  fraction had  a higher value than that ot  the secorid fraction, and gradually lower value for• the third fraction. It  was found  from  this study- that the lint  fraction obtained from cananga oil distillation renders  the highest quality oil.

Abstract

Penetapan lhirteralnitrogen menurut metode MgO, Devarda,penetapan organik nitrogen menurut metode Kjeldahl dan penetapan  total  nitrogen menurut  metode  persulphat adakzh sangat umum  dan digunakan aecara  luaa di aeluruh dunia, karena sederhana dengan ketelitian yang memenuhi ryarat. Namun hasil pengamatan akhir-akhir ini menunjuk- kan  bahwa tidak   aemua jenis  organik nitrogen atau  mineral nitrogen dapat ditetapkan kadarnya aecara  teliti dengan menggunakan metode analisis te1'8ebut.Penelitlan..  ini bertujuan untuk  mengetahui ketelitian  penetapan kadar nitrogen dengan metode  te1'8ebutdi ataa untuk  11 jeniB aenyawa organik dan  mineral nitrogen. Hasil penelitian menur.;ukkan bahwa aenyawa azo •dan  benzo aangatrendah ketelitiannya bila ditetapkan dengan metode Kjeldahl dan ge1'Bulphat. Senyawa nitro dan nitroso ketelitian- nya rendah bila ditetapkan dengan metode. Kjeldahl, tetapi sedikit lebih tinggi bila ditetapkan dengan metode pe1'8ulphat.

•Of the forat  pfoductt in •rndonei~,. plywood haa an •im~rlant  '1olitio1'•in mee~•the  need for•t~   f~reiln, ~• By the end of 1986. the contribution of plywood to the tQ.tal export value of forat  pro~ucta ~the     brggest.It accounted for 61. 40~  In the (Qllowingyea.r., the a.,erage gr:owthper. ye~r.of  the•pbwood  expor.t volume was 54.98_%. .          .                                                                                   : The a.im •of  thia atudy   ~  to •know   how far   the a~tual value• of. the plywood  export  aB the fore'!n exchange •Im reached the optimum.  To achieve the aim, two modelB (Model• I and Model II) of linier 11rograming were conatrueted. In •    thia caae, the study   waa conducted on the plywood  mill• in South Sumatra Province.                •                                                                                                                    •The rault   of  the study  revealB that the actual ualue of the plywood  export of thia region has not been optimum. The actual value of the export per month  waa USI 3 342 778 or USI 286. 1/m3. Meanwhile the export ~ue    per month based on the optimizing model of Model I and Model II iB  UBI 4 297 269 or US$'824.  9/m3 and UBI 4 537 673 or UBI 343. 2/m3  respectively.                                                                                                         To reach the optimum  value of export the market area and the export volume• need to be reallocated;tJn increasein volume export  by 1.35%  (Model I) or by  1.04'*'  (Model II) can cause a significant incre•e  in the export value comj'JtJl"ed with the ualue• gained by  the mill.Since the demand of  the Indonesian plywood  export iB prone to increaae, the reault of the optimizing modeZ. can be implemented. However, the optimizing reault of Model II iB preferred particularly with regard to the efficiency of f!&e forest re1ourceuse.
