Judul: Penentuan Biomassa Atas Permukaan Menggunakan Persamaan Alometrik (Non-Destruktif) di Kawasan Hutan Gambut Eks PLG (Blok C dan D) Kalimantan Tengah
Abstrak: The Ex-Mega Rice Project (EMRP) of the one million hectares in Central Kalimantan is one of the biggest field conversion problem in Indonesia. Reclamation activities to becoming rice field followed by construction of drainage channels more rapidly consequence to land fire, loss of biodiversity, and also social-economy implication. The biomass estimation using five methods approach, i.e. Brown (1997), Ketterings et al (2001), Onrizal (2004), Ludang (2007), and specific equation for certain species (locally equation). While the carbon-stock (c-stock) estimated by a half of the biomass. Result of this study revealed that 97% of the vegetations density was decrease during period 1990-1996 until 1996-2000. The analyse outcome using descriptive approach (Mean Absolute Deviation (MAD) and correlation) and inferential approach (One-sample Statistic test) shows that Kettering equation dominantly match, followed by Ludang, and Brown. Output comparation by the biomass and mean C-stock value was heterogenous and decrease significantly from 10-279 t/ha and 75tC/ha during period 1990-1996, to 1.5-115 t/ha and 56tC/ha during period 1996-2000. The spread distribution map visualize clearly the lag of biomass before and after ERMP in 1997. This revealed the importance to conserve and rehabilitate on peatland in order to increase carbon sequestrate activities.

Judul: Pendugaan Biomassa Hutan Menggunakan Citra Resolusi Sedang (Studi Kasus: Hutan Lahan Kering Sekunder Kalimantan Timur)
Abstrak: Perubahan iklim merupakan masalah yang terjadi saat ini yang disebabkan oleh pemanasan global dan dapat diatasi salah satunya dengan menjaga tutupan hutan yang memiliki simpanan biomassa. Perlindungan terhadap biomassa hutan dapat mengurangi emisi karbon dari sektor lahan. Pendugaan nilai biomassa tidak perlu menggunakan cara destruktif, menggunakan citra satelit dapat dijadikan suatu alternatif. Tujuan penelitian untuk memperoleh model penduga biomassa hutan lahan kering sekunder di Kalimantan Timur dan membuat peta sebaran biomassa. Pembuatan model dilakukan secara digital menggunakan indeks vegetasi citra satelit landsat 8 dan data plot lapang menggunakan 39 plot data sekunder berasal dari program FCPF. Pembuatan peta sebaran biomassa dilakukan menggunakan 3 model terbaik. Penelitian ini menghasilkan model terbaik persamaan linier dengan indeks vegetasi GNDVI, dengan persamaan B = 3768,539 GNDVI - 1209,709 yang memiliki R2 sebesar 42,6%., Climate change is a current problem caused by global warming and can be addressed one of which by maintaining forest cover which functions as biomass storage. Protecting forest biomass can reduce carbon emission from the land sector. Biomass estimation is not only estimated by using a destructive method, satellite imagery can also be used as an alternative. The research objective is to develop biomass estimator model in dryland secondary forest and generate a biomass distribution map. Biomass model was developed based on vegetation index of landsat 8 satellite imagery and field data plot using secondary data of 39 plots from the FCPF program. Biomass distribution map was produced using best three models. This research shows that the best model is linear equation model with GNDVI vegetation index, with equation of B = 3768,539 GNDVI - 1209,709 and R2 value of 42,6%.
