Abstract

The khilau is one of sub-watershed of the sekampung watershed. The area was very important due to its function as catchment area which is also located close to TAHURA (great forest park ) Wan Abdurrachman, there for sub-watershed khilau plays a very strategic role in the preservation of biodiversity and climate change.  The study aims were to analyze the carbon determine the total carbon dioxide uptake and oxygen release in the khilau sub-watershed. The carbon stored was extimated by using allometric equation the biomass tree. The biomass expantion factor was employed estimated of  biomass.  The carbon conten multiplication with the value of the conversion of carbon elements to carbon dioxide, while for the oxigen release was estimated by multiplying the value of carbon squestration by the conversion value of carbon atoms to oxygen based on atomic weight. The result showed that carbon stored in the forest was 141,69 tons/ha, it was greater than agroforetry (75,33 tons/ha), shrubs (24,74 tons/ha), annual plant (11,13 tons/ha) and paddy fields (3,45 tons/ha) with a total area of forest 52,22 ha, agroforestry 457,86 ha, shrub 28,74 ha, annual plant 84,8 ha and paddy fields 2,36 ha.  The total carbon dioxide absorbtion was 159.832,73 tons and oxygen release was 426.220,61 tons.

Abstract

Natural agarwood takes a long time to be formed in nature, therefore an improvement technique was required in order to increase the productivity of Agarwood.  One of these techniques was Bioserum injection into the Aquilaria malaccensis.  Bioserum is a nutritious liquid necessary for fungi to live, grow and produce the agarwood.  The purpose of the research was to determine the best Bioserum dosage, the best time of Bioserum reacted, and the best interaction between the two factors in the formation of agarwood.  Factorial Completely Randomized Design (FCRD) with two factors, namely the dosage of Bioserum and time of Bioserum reacted in the Aquilaria malaccensis, was employed as the research design.  The dosage of Bioserum applicated was 0 ml, 2 ml, 3 ml, and 4 ml with 3 replications.  The time of Bioserum reacted in the Aquilaria malaccensis was 1 month, 2 months, and 3 months.  The results showed that the best dosage of Bioserum to form the agarwood was 4 ml/hole.  The best time of Bioserum reacted in the Aquilaria malaccensis to form the agarwood was 3 months.  The best of interaction between of the two factors to form the agarwood was the Bioserum dosage of 4 ml with the time of Bioserum reacted of 3 months.
