“…According to [27], basal area of tree has a high correlation with total carbon stock. This is also corresoinding with [29], who reported that the decline in carbon stocks in the Jangkok watershed (Lombok Island) was closely related to a decrease in the number of large trees, reflecting a decrease in basal area of trees after the forest in the area was converted to agriculture. The carbon stored below the soil surface (7,549 tonnes ha -1 ) is greater in value than the carbon stored above the ground (4,096 tonnes ha -1 ) in Cikalong Wetan.…”

Alternatives of vegetations to store carbon need to be encouraged considering that forests are threatened by widespread destructions. One such vegetation is grasslands which have the potential for carbon storage and to reduce CO2 concentration in the atmosphere. At present, many enterprises have designed grasslands for many purposes. Grasslands at Cikalong Wetan and Little Farmers, West Bandung Regency were established under different pattern of plantation stands. The purpose of this research was to study the potential of carbon stock in grassland vegetation at these locations. Based on RaCSA method, the tree biomass was determined by nondestructive collection of density and basal area of trees, then calculated by an allometric equation. The ground cover biomass was determined by destructive collection of grass and roots. Total measured biomass was multiplied by 46% to obtain carbon storage. Based on the results, the potential of carbon stock in Little Farmers grassland (159,540 ton ha-1) is higher than in Cikalong Wetan (14,482 ton ha-1). Carbon stored in tree biomass gives the highest contribution to overall carbon stock potential in Little Farmers (94.84%) while carbon stored in below-ground understorey biomass gives the highest contribution in Cikalong Wetan (52.13 %). Different management of grasslands and pattern of plantation stands resulting a different contribution of carbon stock in every carbon pool. In order to maintain the carbon sequestration potentials of these locations, an agroforestry management such as agri-silviculture need to be encouraged. This study gives a comparison of the carbon sequestration potentials between two man-made grassland ecosystems. For many enterprises this study will aid in a management planning of man-made grassland in terms of ecosystem services, that is carbon sequestration.

“…In addition to improve the conservation of biodiversity, agroforestry systems also can enhance the ecosystem services provision. In example carbon stock and reduce net emission rates there also agroforestry system contribution (Markum, Ariesoesiloningsih, Suprayogo, & Hairiah, 2013). Santos, Crouzeilles, & Sansevero (2019) in their experiment showed that agroforestry systems provide more benefit of biodiversity and ecosystem services up to 45-65 % than conventional production system.…”

Homegarden-dry field is one of land management form that maintains biodiversity while at the same time synergize the production and conservation. Changes in market conditions pose a threat for monoculturalism on homegarden and dry field. On the basis of this consideration, it is necessary to do a research on trees health in homegarden and dry field. This study aimed to determine the constituent species in the agroforestry system of Kulon Progo, tree health typology in Kulon Progo, and the type of damages to homegarden and dry field tree species in agroforestry. This research method used inventory of species in the agroforestry system and identification of damage to trees using Forest Health Monitoring (FHM). The result showed that there were three typologies of trees' health. Those were classified into typology 1, 2 and 3 in Kulon Progo. The types of damage that present at homegarden and dry field in Kulon Progo are the open wound, galls rust, broken branch, leaf spot, excessive branching, gummosis and termite attack.

“…Kawasan hutan ini telah mengalami perubahan tutupan hutan yang masif terjadi sejak tahun 2000 -2005 akibat penebangan illegal (Muktar, 2011). Sejalan dengan hal tersebut, berdasarkan hasil interpretasi Citra Landsat 5 TM di Kawasan tersebut, telah terjadi penurunan tutupan hutan primer sebanyak 22 % sejak 1995-2010 (Markum et al, 2013;Tratib, 2011). Perubahan tutupan hutan primer tersebut beralih menjadi hutan sekunder dengan beragam sistem penggunaan lahan, diantaranya adalah penggunaan sistem agroforestri.…”

The Sesaot forest area has been managed by the community through the Social Forestry scheme with an agroforestry system. The objectives of the study were to identify the diversity of agroforestry patterns, analyze incomes on various agroforestry patterns, analyze the amount of carbon stock and analyze the most optimal agroforestry patterns. The method used is descriptive through a series of observations, interviews and Focus Group Discussions, to 42 respondents and measurement of carbon stocks in 18 farmer locations. Analysis of agroforestry patterns was carried out by making clusters based on plant dominance, analyzing the amount of carbon using allometric equations and analyzing the optimal value of agroforestry patterns using scoring. Based on the results of the study, it can be concluded that: there are four agroforestry patterns in the Sesaot Forest Area, namely, candlenut dominant agroforestry, mahogany dominant agroforestry, mixed agroforestry and simple agroforestry. The largest income was obtained in the mixed agroforestry pattern and the smallest was in the mahogany dominant. Meanwhile, the largest amount of carb on stock was found in the mahogany dominant and the smallest was in the simple agroforestry. The results of the scoring analysis show that mixed agroforestry practices are in the most optimal category compared to other agroforestry patterns.
