Rotan Potensial dari Hutan Bukit Lubuk Pekak, Merangin, Jambi

Abstract

Rattan is a potential non-timber forest product. It grows in almost all parts of Indonesia, and has been widely used and traded. Indonesia as the largest rattan producer in the world supplies about 85% of world rattan needs. Bukit Lubuk Pekak Forest is part of the Production Forest Management Unit (KPHP) area, Merangin District, Jambi Province. The threat form rattan exploitation is increasing, especially in the Bukit Lubuk Pekak. Therefore, it is necessary to conduct study on the potency of rattan in that area for future conservation efforts. This study aimed to investigate rattan species in Bukit Lubuk Pekak forest, Merangin District, Jambi Province. Information of the potency of rattan is essential to support rattan industries. To complete data of rattan potency from Sumatra, an exploration in this area was carried out in July 2016 in Bukit Lubuk Pekak Forest. The study was conducted by purpossive sampling. Identification on morphological characteristics of rattan were performed on all parts of plants including fruits and seeds (if available). The results showed that there were four rattan genus in Bukit Lubuk Pekak Forest: Calamus, Daemonorops, Korthalsia, and Plectocomiopsis. They consisted of nine species, namely Calamus caesius, C. exillis, C. insignis var. longispinosus, C. laevigatus, C. tumidus, Daemonorops micracantha, D. didymophylla, Korthalsia flagellaris, and Plectocomiopsis geminiflora. Among the nine species, two species that is Calamus caesius and Daemonorops didymophylla have been cultivated for industry raw materials and drug, respectively.

Population of Potential Rattan in Bukit Tiban Protection Forest, Batam, Indonesia

“…The structure of the rattan species can generally be distinguished from the midrib of leaves, flowers, and fruit (Kalima & Rustiami, 2018). The number of species found on this location was higher compared to the exploration result from Bukit Lubuk Pekak Forest, Merangin, Jambi, where the rattan species were found less than ten species (Kalima et al, 2019). It showed that BTPF has more potencies of rattan to substitute the use of current commercial rattan.…”

“…Bukit Tiban, Sekupang is the only protected forest in Batam Island (Yuliastrin, 2014), and this result was high enough for rattan population in a protected area compared to the other observations from Andayani et al (2018) that only found seven rattan species in Mandanau Island, Belitung. Another result from Kalima et al (2019) found nine species of rattan in Bukit Lubuk Pekak forest, Merangin, Jambi. The high density of rattan species in Bukit Tiban, Sekupang need to be monitored since the disturbances or the threats to this forest were also high, such as forest fire in a dry season and illegal land conversion.…”

“…We used a comparative method through the morphological aspect comparison between unidentified herbarium specimens from the field and herbarium specimens that have been identified and collected in the Herbarium Laboratory of Botany and Forest Ecology, Forest Research and Development Center, Bogor to determine the scientific name. The identification of rattan species also referred to Kalima & Rustiami (2018); Dransfield et al (2008), as well as several rattan studies in Indonesia such as the study from Kalima (2008), Kalima & Jasni (2015), and Witono et al (2013).…”

“…Rattan, as our object of study, is rattan species in the BTPF. Rattan in this study is referred to as a thorny liana plant climbs using flagella or sirus, scaly fruit, slippery trunk, and belongs to the family Arecaceae (Calamoideae) (Kalima & Rustiami, 2018).…”

“…We prepared the route for exploring and collecting all the data needed in the BTPF. The research parameters are the morphological characters observed, including habitus, leaves (such as color, leaflets, leaf arrangement, knee, ocrea, and climbing organ), and fruit (Kalima & Rustiami, 2018 characteristics of rattan species based on the local information about the existence of rattan species in this area. All data obtained were recorded in tally sheets such as date and place of collection, name of the collector, genus, local name, and distinctive note regarding its color.…”
