Small-scale paperboard industries that use the mixed ran-materialef paper-mill sludge and waste currenty encounter diffimlties obtaining the latter item. In other side, uoad wastes generatedfrom the logging of industrial plantation forest are potentially abundant and sofarnotyetutilize deffectivel y As the releuance, a trial has been carried out on paperboard111a111ifact11re 11si11g the mixture efpulp from industnal plantation forest'swood-logging waste and paper- mill sludgeat two uarious proportions,i.e. 25%:75% and 100%:0%. The processing of those wastes intopulp wascondutted in a semi-pilot scale cooking digester usingthe semi-cbemical soda pulping conditions, i.e. alkali (NaOH) concentration at 14% and 16%, ratio ef mastesto cooking liquor 1:5.5, maxinmm telyl peratureal 120 C kept far 3 boars under 1.2-1.5 atmosphericpressnres.

This researchaimed to look into the resistanceof 25 rattan speciesagainst subterranean termites(Coptotermes curvignathus Holmgren). Each rattan species was prepared into testsamples with length of 2 cn1 and particular diameter depending on the rattan species itself. The test took place in jampot into which were previous!Jput 200 subterranean termites of the morker type,being active and healtlly. Theparameterstestedinc/tidepercentagesof rattan-weightloss and number of termitesurviva4 which were then statistical JanalJzedaid,furtherused to classifythe 25 rattan species in accordance with their resistance class. In addition, degree of attack fly termite was suljective/y examinedon the rattan. Results revealedthat out of the 25 testedrattan species,7 species (28%) were categorizedas high-resistance class (class I and II), while the rest .i.e. 18 species (12%) belonged to low-resistanceclass (class Ill,IV; V). In their uses, rattan species with-low-resistanceclass require a thoroughpreservationprocess. It also turned out that despite being suljectively examined, the degreeof termiteattacks correlatedpositive!Jwith the rattan weightloss (R = + 0.618**) and with thenumberof rattansurvival (R = + 0.697**).

This paper present research regarding the application of charcoal-incorporated organic fertilizer(OOF) and charcoal-incorporated organic fertilizer(CIMOF) lo the growth media for Shorea crysopllyila seedlings, which lasted separately but conrurrently far 6 month in the greenhouse. This research ainud to look into the effect of OOF and CIMOF mplfy!11ents on thegrowth responses i.e. weight and diameterof those seedlings. & suits revealed that the use of one tablet of CIMOF brought about significant effect on the height and diameter growths of Sborea crysopllyila seedlings, in that thereIJJQS an increase as much 4 3.9% the height and 4 9.3% the diameter as those of the control (without CIMOF). Meanwhile, the use of OOF seemed less effective lo inflictmch increase than that of CIMOF. The increase was only 33.65% and40.06%forheightand diameter, respectively It can be inferred that to enhance thegrowth of Sbores crysupilyila seedlings, it was s11.fficient by msten plqyingone tablet of CIMOF rather than the use of OOF. Further, the use of CIMOF tablet proved fl/Ore effective increasing the seedlingheight and diameter.
