The potential of carbon deposits to residual stand in Tongkonan lembang Buri' garden of Tana Toraja

Abstract

Abstract Home garden is one of the traditional farming systems consisting of the composition of annual plants and seasonal crops. Tongkonan garden is one of the traditional farming systems that can be found in Toraja, specifically Tana Toraja, Rembon District. With the tree composition, Tongkonan garden is also able to absorb carbon and reduce CO 2 emissions from the air. This study aims to determine the carbon storage at Tongkonan Garden in Lembang Buri’. The sample plot was using the method proposed by Matthew Delaney, which was to select ten plot of Tongkonan Garden with a size of 25 × 25 m. The sample plot based on purposive sampling method with consideration of having many trees in the Tongkonan Garden stand. Each of which was divided into eight subplots, namely four subplots in each corner of the Tongkonan Garden and four subplots in the middle, each of which has a diameter of 8 m. To find out the value of tree biomass, using the allometric equation by measuring the diameter of trees at breast height and measuring tree height specifically for palm species. Measurements of litter biomass and undergrowth were carried out in 1 x 1 m subplots of 3 times in the sample plot. The results showed that the average value of carbon storage in trees was 37,031 tons/ha (98,239%), undergrowth 0,246 tons/ha (0,652%) and litter 0,418 tons/ha (1,110%).
