Khilau Watershed (DAS) is one of the sub-watersheds with the status of should be restored. The biophysical conditions of the watershed must be assessed, to determine the suitable actions for land rehabilitation. The purpose of this study was to provide a comparative analysis of baseline data on the biophysical conditions of the Khilau Sub-watershed area based on edaphic and climatic parameters. Data collection method was using cluster sampling in five types of land cover. The data analysis used spatial and laboratory analysis. The results showed that agroforests and annual crops mostly were on moderately steep to steep slopes (15-45%) and all primary forests were in steep slopes (>45%). All the land covers were ultisol. The primary forest has the highest CEC, N-total, P-availability, and C-organic among other land covers. The agroforest has the most acid pH soil among other land covers. The primary forest has the most rapid soil permeability compared to other land covers. The primary forest has the lowest temperature and the highest humidity compared to other land covers

This study aims to know the public perception of water usage and to determine the economic value of water from any use of and willingness to pay for forest and land rehabilitation.This research is held on March-Mei 2012 at Pesawaran Indah village, Padang Cermin, Pesawaran.To predicted the total economic value of water resources were used WTP method. The results of this study showed the total economic value of water is as much as Rp 1.705.844.764,-/year.These show that the public has higher willingness to pay of the total value, so it can be concluded that assess a community resource, Pesawaran Indah village has a perception of the water use is still low. One of factor is the exceeding availability of water resources, the community habit as free rider. It needs a policy of water management to maintain and conserve the water resources.

This research aims to determine dominant vegetation and amount of carbon absorption of agroforestry systems.This research held at Pesawaran Indah Village, Padang Cermin Sub Distric, Pesawaran Distic, Lampung Province on April - June 2012. It is used Summed Dominance Ratio (SDR) methode, vegetation of INP (Indeks Nilai Penting) and than to calculate the carbon absorption by allometrik equation. Agroforestry land lies on fisiography category.There are three fisiography to ease in obtaining the data. There are low land, middle land, up land and forest hamlet. On low land the dominanat vegetation for tree phase is Teak (Tectona grandis), and for pole, sapling and seedling phase is dominant Cacao (Theobroma cacao).On middle land the dominanat vegetation for tree phase is Avocado (Persea americana), the pole, sapling and seedling phase is dominant Cacao (Theobroma cacao).On up land the dominant vegetation for tree phase is Waru (Hibiscus macrophyllus), the pole, sapling and seedling phase is dominant Cacao (Theobroma cacao). On village forest the dominant vegetation for tree phase is Taboos (Crescentia pujeta), pole phase is Champaca (Michelia champaca), sapling phase is Bamboo (Gigantochloa apus) and seedling phase is hevea (Hevea brasiliensis). The results of carbon above absorption on agroforestry lands at Pesawaran Indah Village is 118,96 Mg/ha (low land), 104,16 Mg/ha (Middle land) and 89,01 Mg/ha (up land) and 526,43 Mg/ha (forest hamled).

Mangrove litter leaf represent the organic substance supplier towards fertility of mangrove ecosystem, that able to support the mortal life within. The area of forest of mangrove represent the nursery ground, feeding ground, and area of spawning ground for various fish type, prawn and other biota sea and also as producer of amount of detritus for plankton as main foods source of the sea. The objectives of this research were to know production and decomposition rate of mangrove litter leaf in the mangrove ecosystem of Durian Village and Batu Menyan Village, Padang Cermin subdistrict, Pesawaran regency. Data was analysed by calculating the dry weight mean of litter leaf production and to counting decomposition rate was using the exponential rank function or from absolute decomposition percentage of litter leaf per day. This research was conducted in two place (station) based on the difference of substrate characteristic. The research conducted from October to December 2013. The productivity of mangrove's litter leaf in both places is 0.56 g/m2/day, where the leaf organ gave the higgest contribution, (66%), stick and branch (14%), flower and fruit (20%). Decomposition rate of mangrove litter leaf showed that at the second station ( 0.20 g/hr) was faster than the first station (0.19 g/hr). Keywords: Decomposition rate, litter leaf litter leaf, mangrove, production

One approach to conservation efforts on forest that has been converted to mixed farms in Tahura WAR which is also the upstream of DAS Way Betung is the application of Payment for Environmental Services (PES)of water. The value of water PES alleged to approach the value of the willingness to accept (WTA) payment to the upstream society as a provider environmental services. The purpose of this study was to determine the magnitude of the WTA from DAS Way Betung society especially water services and the factors that influence it, in addition to know the form of incentives that the public wants. The method used in this study is the analysis of Willingness to Accept (WTA), regression analysis and qualitative descriptive analysis. This research is held on April 2014 at Sumber Agung village, Kemiling, Bandar Lampung city. Based on the results obtained by the analysis of the value of the average WTA respondent is Rp 4,358.33 /tree/year. If the total number of trees on public land is 10,475 whole tree, then the total value of the WTA obtained is Rp 44,935,750.00/year. Factors that significantly affect the value of the WTA is the level of education, land area, and the number of trees. Form of incentives other than money the public wants is a fertilizer aid, rural development like transportation infrastucture, and help seed.

Community forestry program is an effort to save the forests while providing benefits to society. Society was given license to manage forests laden not develop plant species monoculture systems but with agroforestry systems. Canopy multi strata agroforestry systems of benefits economical and ecological that matter to farmers, one of which can provide income for farmers. So that the implementation of agroforestry systems community forestry land is expected to be a solution the needs of land as a factor of production as well as to the recovery of the forest is mainly a function of the life support system. The goal of the research determined the structure of income, the factors that influence of income and welfare level of coffee agroforestry as participants community forestry program. To analyze factors affecting farmers' income analyzed by linear regression of multiple and welfare of farmers based price of rice by Sajogyo 1997. From the reckoning, income of farmers amounted of coffee agroforestry to Rp 14,649,631/KK/Year and Rp 6,321,690/KK/year of activity non agroforestry dominated farming and as much as 38,10% of farmers prosperous based on income from the activity coffee agroforestry at community forestry.
