Abstract

Tahura Orang Kayo Hitam is one of the locations that was severely damaged due to forest fires that occurred in the peat area of Jambi Province. Natural regeneration is a possible option in restoration activities and requires the presence of a mother tree and seed dispersing agents . This study aims to identify seed dispersing agents in the Orang Kayo HitamTahura and has been carried out for 3 months from June to August 2020. These tree species were obtained by a sampling method with a plot size of 20x20 m determined by a 500 m long transect from outside the forest to inside the forest. All trees with a diameter above 10 cm were measured and their species identified. Seed dispersing agents were identified by literature study, photo analysis and discussion with locals. The results of field data indicated that the species found in the study area were spread by wind and wildlife. From the 32 tree species were found, 10 species (32%) were spread by the wind and 22 species (68%) were spread by wild animals. The preliminary conclusion of this study is that wind and wildlife are very important in the distribution of tree seeds in burned areas.

Abstract

Pine resin production is influenced by several factors, including altitudes and the different classes of age . In addition, the productivity of pine resin is also influenced by weather and climate. The aim of study that entitled oductivity of Resin Pinus Merkusii Jungh Et De Vriese in Several Class Ages and Altitudes, was to investigate pine resin productivity in Forest Management Resort Guyangan, Perum Perhutani, based on variation of altitudes and class ages classified by Perum Perhutani. This study used resin production data that taped by quare methode from Forest Management Resort Guyangan, and then data were analysed with microsoft office excel. The result of this study showed that the highest pine resin productivity is 0.22 kg/tree/month for class age (KU) V and IV, and the lowest pine resin productivity, i.e. 0,19 kg/tree/month is for KU VII. Based on altitudes, resin productivities for 500-799 (mdpl) and 800-999 (mdpl) were 0,22 kg/tree/month and 0,20 kg/tree/month respectively. Based on this study, it can be concluded that the higher altitudes the lower pine resin productivity. Meanwile basedon the age class, the productivity of pine resin in different age class shows different values.
