PENDUGAAN POTENSI POPULASI DAN EKOLOGI JELUTUNG (Dyera costulata (Miq.) Hook. F) DI HARAPAN RAIN FOREST (HRF-PT REKI) JAMBI Rahila Junika Tanjungsari; Ervizal A.M. Zuhud; Iskandar Z. Siregar

Jelutung (Dyera costulata) is a native species from Sumatra and Borneo. D. costulata has various benefit, for human and environment. The main use of jelutung is the latex as industrial raw materials. Jelutung population in natural habitat has decreased and the product is no longer available in market. The objectives of this research were (1) to identify population of jelutung in Harapan Rain Forest-PT Restorasi Ekosistem Indonesia (HRF-PT REKI), (2) to analyze habitat characteristics of D. costulata on HRF. The study was conducted in May-June 2015 at HRF-PT REKI, Batanghari District, Jambi. Data were collected by interview and vegetation analysis with sample plot of 2 ha. Result this study showed, D. costulata stand condition in HRF was abnormal. Jelutung tree diameter class is a class at most a diameter of 40 cm - 60 cm by 26 individuals D. costulata can grow in temperature condition 23oC -28oC and soil condition that are very acidic and poor of nutrient. But, species richness around habitat jelutung a relatively high. In conclussion jelutungs of the study could be used to local conservation and management for sustainable used.Keywords: ecology, jelutung, potency

Shorea is a genus of the Dipterocarpaceae family which shows high economic and ecological values. Currently, market demand for wood is still met from natural forests that are degrading due to over exploitation. The degraded forests are included in the rehabilitation program that require significant number of planting stocks, mainly from seedlings or wildlings. Correct species identification of planting stocks, particularly wildlings, is an important first step in planting activities and it is relevant with Shorea spp planting stocks due to leaf morphology traits. This study was aimed to examine the traits of leaf morphology of four Shorea species for easy field identification. Samples were taken from five trees for each species. Morphological trait identification was conducted by leaf observation and measurement. The results showed that all four species had the same apex shape. Six of the twelve morphological characteristic of the variable character can influence the morphological characteristics of the leaves, namely the roving leaf, leaf area, leaf length, aspect ratio, form factorand perimeter ratio of diameter. S. leprosula is similar to S. parvifolia, while S. ovalis is similar to S. guiso. Shorea leaf character S. parvifolia differentiated from S. leprosula, while Shorea ovalis similar to Shorea guiso. The LP variable (length from the base of the leaf to the widest point of the leaf) is a variable that can be used as aleaf morphological characteristic of the four Shorea which are compared because each one has a different value. S. ovalis has the highest LP value, followed by S. guiso and S. leprosula, while S. parvifolia has the lowest LP value. Keywords: apex shape, identification, leaf morphology traits, Shorea

Anak Dalam Tribe (Suku Anak Dalam; SAD) used jelutong in their daily live. But nowadays, jelutong population was reduced. Increase the forest change area decrease the habitat preference of jelutong. It need the strategy and technique to conservation jelutong without conflict with local people interest. Traditional management of jelutong among SAD in Bukit Duabelas National Park (Taman Nasional Bukit Duabelas; TNBD) benefits to understanding technique used of jelutong latex and understanding ecological knowledge SAD for strategy of conservation jelutong, among other are to described jelutong population status in TNBD. The research was conducted by using focus group discussion and indepth interview 40 respondent to examine management and use of jelutong. In addition, vegetation analysis was also conducted to determine the status of jelutong population by 8 sampling plots with census technique in 2,88 ha area. It was determined that SAD use latex of jelutong especially for comodity. Traditional technique applied to all methods tapping, production, and marketing latex. Time latex tapping done in early morning on 5 to 6 am because sunrise decreased latex production. Latex mixed with samak (Syzygium pyrifolium) or vinegar 61, allowed to stand until thickened and forming lumps fit the mold. The local management of this species is based on simple maintenance and tapping latex of individuals in the swamp area, dryland area and homegardens agroforest.The structure of jelutong population in TNBD was destructed which are distribution number of jelutong per ha young stage less than mature stage. Keywords: Anak Dalam Tribe, bioprospecting, conservation, Dyera spp., ethnobotany
