Full text linkIndonesia is a country that is rich in forests, since centuries ago it has interacted strongly with forests, so that forests and humans have become one unit. Forest management in Indonesia is carried out to provide benefits for citizens in general and forest communities in particular. The benefits in question can be realized through optimal forest planning and management in accordance with forest functions. Determination of appropriate forest management is carried out to realize sustainable forest conditions and optimally benefit the community, both directly and indirectly. Law 41 of 1999 on forestry mandates the establishment of forest management areas at the provincial, district/city levels, and management units in the form of the smallest forest management units (KPH) according to their main functions and designations. The implementation of forest management in FMUs is an embodiment to carry out forest management which includes forest management activities, the government's efforts to emphasize the law above are the issuance of PP 6/2007 in conjunction with PP 3 of 2008 concerning forest governance, Preparation of Forest Management Plans, as well as forest utilization that is sustainable. explained that KPH includes Conservation KPH (KPHK), Protected KPH (KPHL), Production KPH (KPHP). This research was conducted at the location of the Production Forest of Karya Mukti Village, Dampelas District, Donggala Regency. Implementation time from October to December 2014. Sources of data obtained in this study consisted of secondary and primary data.
