    Peluang Dan Tantangan Perhutanan Sosial Di Sub Das Lematang : Kasus Di Hutan Penelitian Suban Jeriji, Sumatera
    (wahyu sari yeni, 2018-09-05) Winarno, Bondan
    State forest in Indonesia is facing of tenurial issue that growing to be a complex situation to resolve. This paper highlights the opportunities and challenges of establishing social forestry in Suban Jeriji forest research, South Sumatra. Data are collected by survey using questionnaire, interview with key informants, and focus group discussion from April 2016 – October 2017. This research shows that almost all of the area in Suban Jeriji forest research has become rubber area occupied by local and outsider people for the last 10 years. The function of the forest change from seed production area into research forest occured in 2014 under the management of of Palembang Environment and Forestry Research Institute. Some of the people realize the status of the land is forest and they will open the commnication to find win-win solution to manage the forest land. Rubber is an established commodity for the people in the forest that potentially combine with other tree species and agriculture species in form of agroforestry. To design and impelement social forestry model in Suban Jeriji forest research,these are some challenges to deal with: (a) strengthening the concept in forest research management and budgetting related with social forestry; (b) capacity building of the research institution; (c) building network and institution with local community and other stakeholders; (d) analysis the options of social forestry model based on agroforestry commodities and market analysis. This forest potentially can be a field laboratory to build a role model of adaptive social forestry in South Sumatra.

    The objective of the this research was: 1) to study the effect of agroforestry technique (Scenario 2) on water discharge as an effort to control discharge derived from Ciliwung Watershed Upstream at this time (Scenario 1), 2) to study the effect of combination of agroforestry technique with several soil conservation technique to produce zero runoff on water discharge an effort to control discharge derived from Ciliwung Watershed Upstream (Scenario 3), 3) to get comparison the effect of Scenario 2 and Scenario 3 conservation technique to produce zero runoff on existing condition (Scenario 1) in controlling discharge derived from Ciliwung Watershed Upstream. Validated A SWAT Model was used to simulate 3 (three) scenarios (Scenario 1-existing condition, Scenario 2-application of agroforestry to reach canopy cover of 60% and increase 20% of existing infiltration, and Scenario 3-combination of agroforestry technique with other soil conservation techniques to produce zero run off). The result show that Scenario 2 (agroforestry) and Scenario 3 (combination of technique of agroforestry and several soil conservation technique until produce zero runoff) are able to decline peak discharge and increase discharge when the discharge is low so that decline maximum-minimum discharge ratio drastically or extremely. Scenario 3 produces lower maximum-minimum discharge ratio as compared Scenario 2.
