<![CDATA[Research on vegetation characteristics and vegetation community similarities was conducted in Mount Ciremai National Park. Three vegetation communities found in the southern part of this National Park, i.e. Parigi-Paguyangan Badak-Acip area (PPA), Karamat Purnajiwa area (KP) and Karamat Sanghiang area (KS), Kuningan, West Java, were investigated. Quadrant method with 10 observation plots per ha was used for vegetation analysis whereas the Jaccard and Sorensen similarity indices were used to evaluate community similarities among the three locations. Vegetation community in PPA (1.100 â 1.580 m asl) was highly dominated by Castanopsis argentea (saninten). This was quite different with the vegetation communities of KP and KS (1.000 â 1.200 m asl) that were dominated by Horsfieldia glabra (kalapa ciung) and several other co-dominant species, such as Sterculia sp., Ficus benjamina and Ficus glabella. Further analysis using Jaccard Similarity Index (lsj) showed that the vegetation communities of KP and KS had a relatively high similarity.]]>

<![CDATA[Cestrum aurantiacum Lindl. is an exotic species found in native remnant forest of GPNP which is located inside the Cibodas Botanic Garden (CBG). Risk assessment is an important tool to choose best decision for invasive plant management. Risk assessment analysis on C. aurantiacum in Cibodas Botanic Garden was conducted using Multi Criteria Decision Analysis (MCDA) method. Analytical Hierarchy Process (AHP) used in the valuation process. Three sub-criteria used: minimizing the ecological impact, minimizing the management cost, and maximizing the public acceptance. Five management alternatives were used: do nothing (DN), eradication (E), containment (C), bio-control (BC) and harvesting (H). Harvesting (H) recommended as the best management decision for C. aurantiacumin at CBG remnant forest. This harvesting decision is not only creating environment/ ecosystem remediation but also as sources of fund in the management activity of the area.]]>

<![CDATA[Due to potential impact of invasive alien (exotic) species to the natural ecosystems, inventory of exotic species in the Cibodas Botanic Gardens (CBG) remnant forest area is an urgent need for CBG. Inventory of exotic species can assist gardens manager to set priorities and plan better responses for possible or existed invasive plants in the CBG remnants forest. The objectives of this study are to do inventory of the exotic species in the CBG remnant forest and to determine whether several environmental variables play role to the existence of exotic species in the CBG remnant forests. There are 26 exotic plant species  (23 genera, 14 families) found and recorded from all four remnant forests in CBG. Cluster analysis of four environmental variables shows that clustering of environmental factors of exotic species correlates with the abundances of those exotic species. The relation between environmental factor clusters and the abundance of those exotics signify the role of environmental variables on the existence of exotic plant species. The information of exotic plant species in the remnants forest is the base information for gardens manager to manage exotic species in CBG remnants forest. The relation of several environmental factors with exotic species abundance could assist gardens manager to understand better the supportive and or suppressor factors of exotics in the CBG remnants forest. Further study on these species is needed to set priorities to decide which species should be treated first in order to minimize the impact of exotic plant species to native ecosystem of CBG.]]>

<![CDATA[Preventative management, such as framework-based assessment, considered as the best option for invasive species management. Alternatively, risk assessment can be conducted based on traits of occurred invasive species to build prediction system for invasive risk assessment. This study aimed to test whether trait-based assessment system can differentiate the escaped from non-escaped exotic collections of botanic gardens and to compare the reliability of trait-based versus framework-based risk assessment on differentiating these escaped from non-escaped exotics. In this study, Bayesian logistic regression analysis was conducted to assess the reliability of framework-based and trait-based risk assessment systems. For trait-based system, clear effect of leaf trait, height, and dispersal method to escape probability was detected. For framework-based system, clear effect of Tropical Weed Risk Assessment Protocol on escape probability was detected. Leaf trait, dispersal method and height are reliable predictors for escaped probability of botanic gardens exotic collection. The fact that the reliability of trait-based assessment systems is better than the commonly used framework-based system is the main novel finding in this study. This finding implies that trait-based is better than framework-based for invasive species risk assessment approach in Indonesian botanic gardens. Trait-based assessment also a relevant tool to support management with limited resources to conduct adequate early risk assessment.]]>

<![CDATA[Penyebaran Cestrum aurantiacum Lindl. di hutan remnant sekundair Wornojiwo Kebun Raya Cibodas (KRC) dianalisis dalam penelitian ini menggunakan Nearest Neighbor Method. Peranan (korelasi) faktor lingkungan terhadap pola penyebaran C. aurantiacum dibandingkan dengan jenis pohon asli dan dilakukan dengan menggunakan cluster analysis. Faktor-faktor lingkungan yang digunakan dalam cluster analysis ini yaitu: intensitas cahaya, keasaman tanah, kelembapan tanah dan kelembapan udara. Hasil analisis penyebaran menunjukkan bahwa jarak penyebaran C. aurantiacum hampir lima kali lebih besar daripada penyebaran yang diasumsikan terjadi secara acak. Hasil cluster analysis menunjukkan bahwa intensitas cahaya berhubungan secara nyata dengan penyebaran C. aurantiacum di hutan Wornojiwo. Intensitas cahaya rata-rata di plot dengan C. aurantiacum lebih besar dibandingkan dengan plot tanpa C. aurantiacum. Contoh pengaplikasian hasil penelitian ini adalah memprioritaskan eradikasi C. aurantiacum yang ada di pinggir hutan daripada yang ada di bagian tengah. Hasil penelitian ini juga mempertegas pentingnya memelihara tegakan hutan alami untuk memelihara naungan hutan.]]>

<![CDATA[The study of exotic epiphytes on tree ferns is relatively scarce. Biological invasion of exotic epiphytes may imply negative consequences to native epiphytes and tree ferns, which are important components in tropical mountainous rainforest ecosystems. This study surveyed exotic epiphytes on tree ferns in Cibodas Botanical Gardens (CBG) and adjacent forests next to CBG. The objectives of this study are: a) to conduct inventory study of exotic epiphyte species on tree ferns, b) to examine how different these exotic epiphytes from each other based on their micro-climate preferences, c) to conduct invasive risk assessment of those exotic epiphytes, and d) to model the effect of environmental factors and host (tree ferns) characteristics to the occurrence of exotic epiphytes on tree ferns. We conducted multi-dimensional analysis to examine how different these exotic epiphytes based on their micro-climate parameters. We used Weed Risk Assessment (WRA) framework to estimate the invasion risks of surveyed exotic epiphytes. We performed Bayesian logistic regression to test the correlation between environmental and host characteristics and the occurrence probability of exotics epiphytes on tree ferns. We found 13 exotic epiphyte species on two native tree ferns species (Cyathea junghuhniana and Cyathea contaminans). Multidimensional analysis showed that Axonopus compressus is very different from other exotic epiphytes due to its environmental preferences. Ageratina riparia and Clidemia hirta were exotic epiphytes with the highest invasion risks. Therefore, we suggested that A. riparia and C. hirta are more likely to become invasive and may contribute significant impacts to native ecosystems. Lastly, the presence of Austroeupatorium inulaefolium as exotic epiphytes in tree ferns negatively correlated with the host height. Further study is needed to incorporate biological traits of the exotic epiphytes and more specific environmental parameters such as light chromatic quality in to the exotic epiphyte occurrence model. This study provides evidence for the existences of exotic epiphytes on tree ferns. The result of this study may also indicate that host characteristics and micro-climate factors could play important roles to inhibit the occurrence of exotic epiphytes on tree ferns.]]>

<![CDATA[Andaliman (Zanthoxylum acanthopodium) is a specialty spice widely found in the Provinces of North Sumatra and Aceh, Indonesia. The fruit is usually used by Batak people in North Sumatra as a food ingredient to cook Batak’s cuisine such as arsik, tombur, and naniura. It is also used as one of the ingredients to make Indonesian spicy sauce called sambal. Andaliman fruit is reported to eliminate the undesirable smell in fish and raw meat. Moreover, it could also reduce total volatile base nitrogen content in fish which helps to prevent spoilage. Furthermore, andaliman has been reported to contain bioactive compounds which act as antioxidant, antimicrobial, anti-inflammatory, anti-aging, anti-acne, and anti-halitosis effects. This review focuses on the botanical aspects of and health potential exhibited by andaliman.]]>
