Judul: Potensi Reduksi Emisi Karbon Melalui Pengelolaan Hutan Alam Produksi (Studi Kasus di IUPHHK PT. Sarmiento Parakantja Timber, Kalimantan Tengah)
Abstrak: One of requirements increase carbon stocks, carbon absorption, and prevent the emission of CO2 in the forest with sustainable forest management. Sustainable forest management such as make permanent sample plots (PSPs) for monitoring the standing stock. PSPs on the planted area of 0,5 ha and planted three kinds of family Diptero. Shorea parvifolia, S. leprosula, and S. johorensis. Total average diameter increment in planted path of 1,29 cm/yr and the average volume increment of 5,69 m³/ha/yr. PSPs on the line between has an average volume increment in family Diptero. diameter > 20 cm of 3,56 m³/ha/yr , less than the average volume increment family non Diptero. Diameter > 20 cm of 3,96 m³/ha/yr. Calculation of carbon stocks and carbon emissions are simulated for 30 years using three schemas. Scheme 1 has a stock of carbon 12.395.834 tC and the level of carbon emissions-1.777.171 tCO2e. Scheme 2 has a stock of carbon 11.863.143 tC and the level of carbon emissions 525.612 tCO2e. Scheme 3 has amount of the largest carbon stock is 12.736.279 tC and the smallest of -2.851.756 tCO2e. Scheme 3 is more feasible to be applied in the opening of forest areas.

Judul: Potensi reduksi emisi karbon melalui penerapan pengelolaan hutan lestari di areal hutan konsesi PT Salaki Summa Sejahtera, Provinsi Sumatera Barat
Abstrak: A management unit (MU) of a forest concession holder implementing the sustainable forest management (SFM) principles, could be involved in REDD+ and carbon trading project. The fact, the strategic in implementing the REDD+ and carbon trading in MU level is still lack of pilot project and methodology. Therefore some scenarios must be developed and tested to find out the best potential of carbon credit in MU level. The objectives of the research were: (1) to calculate carbon credit in some SFM scenario, (2) to analyze of carbon trading project feasibility, and (3) to determine carbon stock recovery period of logged over area (LOA). The result revealed that carbon stock and carbon credit of LOA was affected by timber cutting intensity. 6th scenario with lowest AAC (annual allowable cutting) obtained greater carbon credit and profit coming from timber harvesting income and carbon trading. In other hand, this scenario has shortest duration of carbon stock recovery period (27 years) and shorter than its cutting cycle. In this case, the MU has to recalculate and to decrease its AAC to have highest benefits from carbon trading in the same cutting cycle period. It will provide double benefits from carbon trading, those are contribution in achieving the SFM purposes (production, ecology, social) and climate change mitigation.
