Description:
Red meranti trees can produce forest products instead of wood in the form of tengkawang fruit that has high economic value. Tengkawang fruit (ilipe nut) will produce tengkawang oil (borneo tallow) which is used as a chocolate making ingredient, cosmetic material, folk remedies, soap and margarine. The population of meranti species producing tengkawang is currently in decline so it takes effort in conserving the tree species. There are about 13 types of meranti tengkawang producers in Indonesia including Shorea pinanga, Shorea macrophylla and Shorea stenoptera. The three types were planted in land span restoration efforts conducted in Gunung Dahu Research Forest, Leuwiliang Bogor.

Successful planting of tengkawang species outside of their natural habitat, especially its use as a type of restoration in degraded and open areas requires growth analysis. This research aims to analyze the success of planting using high growth characteristics, diameter and riap Shorea stenoptera, Shorea pinanga and Shorea macrophylla, as well as environmental factors related to growth in Gunung Dahu Research Forest, Leuwiliang, Bogor as information materials and evaluation of the development of the three types going forward.

Advantages:
This research shows that native species, especially meranti tengkawang producers, are able to grow well in the restoration land of Gunung Dahu Research Forest, Leuwiliang, Bogor which was once degraded and open land and is not a native habitat of the breed. In addition, meranti tengkawang producers used in the restoration of land spans in the area have also produced tengkawang fruit that can later be utilized by the surrounding community.

Uses:
This research can be used as a learning material, evaluation and basis in the creation of regulations and policies related to the selection of commodities in restoration and rehabilitation activities of forests and land. Thus, native species especially meranti tengkawang producers can be used as alternatives or commodity options in restoration and rehabilitation activities, as well as a way or effort in conservation of such types.
