Peat swamp forest is an important pool of terrestrial carbon stock (C-stock). Therefore, research on change of C-stock and its economic value of peat swamp forest conversion to pulpwood industrial plantation forest is important. The objectives of this research are to know the change of C-stock on peat swamp forest conversion to pulpwood industrial plantation forest, and to get the carbon economic value of peat swamp forest and pulpwood industrial plantation forest. The result showed that conversion from logged over and secondary forest causing the decrease of C-stocks of 103.53 and 61.02 t ha-1 year-1, while conversion from degraded forest causing the increase of C-stocks of 22.47 t ha-1 year-1. REDD project on pulpwood industrial plantation forest from degraded land causing the increase of NPV of 20.21% and 51.13% for compensation prices US$ 9 and 12 tCO2-e-1. REDD project with conservation on secondary forest gave lower economic value than pulpwood industrial plantation forest at all compensation prices simulation, and REDD project with preservation logging gave higher economic value than pulpwood industrial plantation forest at compensation price US$ 12 tCO2-e-1. REDD project on logged over forest gave higher economic value than pulpwood plantation at compensation prices US$ 9 and 12 tCO2-e-1 (both on conservation and preservation logging scenarios).

A management unit (MU) of a forest concession holder implementing the sustainable forest management (SFM) principles, could be involved in reducing Emmission from Reforestation and Forest Degradation (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: to calculate carbon credit in some SFM scenarios, to analyze of carbon trading project feasibility, and 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. The 6th scenario with lowest annual allowable cutting (AAC) 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.

Forestry sector is the biggest carbon emission contributor in Indonesia which is mainly caused by deforestation. In Kalimantan island one of the largest island in Indonesia has a significant area of forest cover still can be found although an alarming rates deforestation is also exist. This study was purposed to established spatial model of deforestation in Kalimantan island. This information is expected to provide options to develop sustainable forest management in Kalimantan trought optimizing environment and socio-economic purposes. This study used time-series land cover data from the Ministry of Environment and Forestry (2000 – 2013) and is validated by SPOT 5/6 images in 2013. The spatial model of deforestation were developed using binary logistic. The results of logistic regression analysis obtained spatial model of deforestation in Kalimantan = 1.1480714 – (0.033262*slope) – (0.002242*elevation) – (0.000413*distance from forest edge) + (0.000045*Gross Regional Domestic Product). Validation test showed overall accuracy about 79.64% and 77.01% for models of deforestation in 2000–2006 and 2006–2013 respectively.

In natural resource management, it is necessary to group regions based on the similarity of their spatial and non-spatial characteristics, to efficiency and effectiveness Therefore, this study describes the re-grouping of the twelve island clusters established by the provincial government of Maluku into more homogeneous classes. The re-grouping was carried out based on the biophysical conditions of the regions, therefore, it could be used as the basis for determining the forest management units. The results showed that the twelve designated island clusters could be simplified to eight more homogeneous island clusters with 86.4% accuracy and 82.2 validation. It also showed that there were thirteen significant changes in the grouping of clusters of the island, including the horticultural crop area (Bf) and horticultural crop production (E). Moreover, when the island cluster is reclassified into 5 classes, the grouping would be more accurate, with 94.9% accuracy and 92.4% validation. This study concludes that there are two dominant factors in the classification of the island cluster in Maluku province namely, biophysical and social.

The forest inventory technique by applying remote sensing technology has become a new breakthrough in technological developments in forest inventory activities. Unmanned Aerial Vehicle (UAV) imagery with camera sensor is one of the inventory tools that produce data with high spatial resolution. The level of spatial resolution of the image is strongly influenced by the flying height of the UAV for a certain camera’s focus. In addition, flight height also affects the acquisition time and accuracy of inventory results, although there is still little research on this matter. The study aims to (a)evaluate the effect of various flying heights on the accuracy of tree height measurements through UAV imagery for every stand age class, (b).estimate the trees diameter and canopy cover for every stand age class. Stand height was estimated using Digital Surface Models (DSM), Digital Terrain Models (DTM) and Orthophoto. DSM and DTM were built by converting orthophoto to pointclouds using the PIX4Dmapper based on Structure From Motion (SFM) on the photogrammetric method to reconstruct topography automatically. Meanwhile, the tree cover canopy was estimated using the All Return Canopy Index (ARCI) formula. The results show that the flight height of 100 meters produces a stronger correlation than the flying height of 80 meters and 120 meters in estimating tree height, based on the high coefficient of determination (R2) and the low root mean square error (RMSE) value. In addition, tree canopy estimation analysis using ARCI has a maximum difference of 9.8% with orthophoto visual delineation. Key words: canopy height model (CHM), digital surface models (DSM), digital terrain models (DTM), forest inventory, UAV image

Forest and land fires are a high source of emissions in South Sumatera. In line with the national policy, South Sumatera Province commits in reducing emission, include emission from the forest and land fire. This research was aimed to assess carbon loss affected by fire in the year of 2015 that covered 3 districts in South Sumatera i.e Musi Banyuasin, Banyuasin, and Musi Rawas. The research was conducted by remeasurement of carbon stocks plots on 4 forests and land type i.e. secondary peat swamp forest, secondary dryland forest, bushes swamp, and forest plantation. Carbon stocks measuring are conducted on sample plots in a rectangular shape of 20 m x 50 m of size for various types of natural forest and a circle shape in the radius of 11.29 cm and 7.98 cm respectively for forest plantation of < 4 years and > 4 years old. Furthermore, carbon stocks in each plot are measured for 3 carbon pools of above-ground biomass, deadwood and litter. The result shows that carbon loss was varying on each forest and land type. The largest number of carbon loss occur on secondary peat swamp forest of 94.2 t/ha that equivalent to the emission of 345.4 t CO2eq. The second largest of carbon loss occur on secondary dryland forest of 36.3 t/ha following by forest plantation and bushes swamp of 18.5 t/ha and 13.5 t/ha. The largest carbon loss on secondary peat swamp forest and forest plantation occur on above-ground biomass pool but secondary dry forest and bushes swamp occur on the dead wood pool.

Luas bidang dasar dan biomassa tegakan hutan dapat dihitung dari data inventarisasi hutan yang diperoleh melalui pengukuran tegakan menggunakan plot-plot contoh dengan ukurandan jumlah tertentu. Tingkat akurasi data dan informasi yang diperoleh dari inventarisasi hutan akan sangat tergantung dari besarnya ukuran dan jumlah plot contoh tersebut. Sampai saat ini, masih sedikit studi yang mempelajari ukuran dan jumlah plot contoh untuk pelaksanaan inventarisasi hutan terutama hutan alam tropis di Indonesia. Penelitian ini bertujuan untuk menentukan ukuran dan jumlah plot contoh optimal untuk pendugaan luas bidang dasar dan biomassa tegakan dalam inventarisasi hutan pada empat jenis ekosistem hutan alam (Hutan Lahan Kering Primer/HLKP, Hutan Lahan Kering Sekunder /HLKS, Hutan Rawa Primer/HRP dan Hutan Rawa Sekunder/HRS). Data yang digunakan adalah data Petak Ukur Permanen (PUP) yang terdapat dalam klaster plot data Inventarisasi Hutan Nasional (National Forest Inventory/NFI) di Indonesia. Analisis data dilakukan untuk mendapatkan nilai koefisien variasi (CV) luas bidang dasar dan biomassa melalui simulasi berbagai ukuran plot contoh. CV menurun dengan meningkatnya ukuran plot, mengikuti tren eksponensial negatif. Ukuran plot optimal untuk HLKP, HLKS, dan HRS adalah 0,40 ha, sedangkan untuk HRP adalah 0,25 ha. Jumlah plot contoh optimal bervariasi sesuai dengan tipe ekosistem hutan dan tingkat kesalahan pengambilan sampel yang diinginkan. Studi ini menegaskan bahwa ukuran dan jumlah plot contoh harus disesuaikan pada setiap ekosistem hutan untuk memfasilitasi inventarisasi hutan yang efisien.

Kayu bawang telah dikembangkan dalam bentuk hutan rakyat di Provinsi Bengkulu, namun hingga saat ini, informasi mengenai pertumbuhan dan hasil jenis ini belum tersedia karena terbatasnya penelitian kuantifikasi pada hutan rakyat. Penelitian ini bertujuan untuk membangun model pertumbuhan kayu bawang pada pola tanam agroforestry kayu bawang + kopi dan agroforestry multi jenis dengan berbagai tingkat kerapatan. Hasil penelitian berdasarkan analisis regresi terboboti adalah bahwa model pertumbuhan kayu bawang untuk pola agroforestry kayu bawang + kopi adalah D = 44,71013 A N ,H=30,41087A N ,danLnV=6,2236-6,8892/A-133,85/N,masing-masing untuk variabel diameter, tinggi, dan volume tegakan. Untuk pola agorforestry multi jenis adalah LnD=2,64378-1,290/A + 111,37/N, H = 8,4351 A N , dan Ln V = 4,0009 - 4,7611/A + 0,21867 ln N. Model-model ini menunjukkan bahwa pertumbuhan tegakan kayu bawang pada pola agroforestry kayu bawang + kopi lebih baik dibandingkan pola agroforestry multijenis. Model tersebut juga menunjukkan bahwa semakin tinggi kerapatan, maka volume tegakan per satuan luas akan semakin besar, tetapi pertumbuhan diameter akan menurun

Hutan gambut merupakan cadangan karbon yang penting. Saat ini keberadaan hutan rawa gambut semakin terancam oleh ekpansi HTI pulp, sehingga penelitian tentang perubahan kandungan C dan nilai ekonominya penting dilakukan. Penelitian ini bertujuan untuk : (1) mengetahui perubahan simpanan C pada konversi hutan rawa gambut menjadi HTI pulp, dan (2) mendapatkan nilai ekonomi karbon pada hutan alam gambut dan hutan tanaman industri pulp. Kandungan C dikuantifikasi dengan persamaan alometrik, dan nilai ekonomi C dihitung dengan pendekatan penerimaan ekonomi proyek REDD. Hasil penelitian menunjukkan bahwa konversi hutan gambut bekas tebangan dan sekunder menyebabkan penurunan kandungan C vegetasi masing-masing sebesar 103,53 ton/ha/th dan 61,02 ton/ha/th. Sedangkan konversi pada hutan gambut terdegradasi menyebabkan peningkatan kandungan karbon vegetasi sebesar 22,47 ton/ha/th. Nilai ekonomi HTI pulp diperoleh sebesar Rp 15,56 juta/ha. Proyek REDD HTI pulp dari hutan terdegradasi menyebabkan peningkatan nilai ekonomi sebesar 20,21% dan 51,13% untuk harga satuan kompensasi US$ 9 dan 12/tCO2-e. Proyek REDD pada hutan gambut bekas tebangan memiliki nilai ekonomi yang lebih tinggi dari HTI pulp pada harga satuan kompensasi US$ 9.00/tCO2-e dan US$ 12/tCO2-e pada skenario UP PAN-KARBON dengan konservasi maupun PHPL. Dengan demikian, penelitian ini menunjukkan bahwa bahwa karbon dari hutan gambut lebih bernilai ekonomi dibandingkan dengan pengusahaan HTI pulp.
