Rafflesia ben gkuluensis Susatya, Arianto & Mat–Salleh merupakan salah satu jenis Rafflesia yang mempunyai ukuran populasi yang paling kecil. Setelah dideskripsikan sebagai jenis baru pada tahun 2005, populasi jenis tersebut mengalami kepunahan secara lokal. Baru tahun 2014, sekelompok penduduk lokal menemukan populasi baru di tempat yang tidak jauh dari populasi awal. Penelitian ini dimaksudkan untuk mengkaji status populasi atribut yang meliputi mortalitas, pertumbuhan kuncup dan ukuran populasi pada populasi yang baru ditemukan dan membandingkannya dengan status populasi 2002 dan 2007. Tiap kuncup dipetakan dan diukur diameternya setiap bulan selama empat bulan. Hasil penelitian menunjukkan bahwa rata–rata subpopulasi adalah 4,75 kuncup dan tidak pernah melebihi dari delapan kuncup. Struktur populasi didominasi oleh kuncup dengan ukuran kecil atau berdiameter kurang dari enam cm. Selama penelitian, jumlah kuncup turun sampai dengan 67%. Diantara sebelas subpopulasi yang tercatat, lima diantaranya mengalami 100% kematian. Sebagian besar kematian terjadi pada kuncup dengan diameter ukuran kurang dari enam cm. Perbandingan dua kelas diameter kuncup memperlihatkan bahwa kelas diameter yang lebih besar mempunyai pertumbuhan kuncup lebih dari dua kali dibandingkan dengan kelas diameter yang lebih kecil.
Rafflesia ben gkuluensis Susatya——Salleh是人口最小的Rafflesia类型之一。2005年被描述为新物种后,当地的物种灭绝。2014年,一群当地人在离第一批人不远的地方发现了新的人口。本研究旨在研究新发现种群的死亡率、芽生长和种群规模等属性的状态,并将其与2002年和2007年的人口状况进行比较。每个月都有一个花苞,并测量它的直径,持续四个月。研究结果显示,平均亚原子种群为4.75个芽,从不超过8个芽。种群结构由直径小于6厘米的芽主导。在研究过程中,花苞的数量下降到67%。在11个不同的人口中,其中5个遭受了100%的死亡。大多数死亡发生在直径小于6厘米的芽上。两节课的直径比较表明,较大的直径比较小的直径长两倍多。

In vitro culture of Amorphophallus titanum (Becc.) Becc. ex Arcang began more than a decade ago at Bogor Botanic Gardens. This paper is a summary of the last three years activities on the propagation of A. titanum. The initial cultures originated from different sources some of them were from the gardens collections. Different parts of the plant were used as explants; axillary buds of the corm, leaf veins and cataphyll. Murashige and Skoog (MS) formulation was used as the basal media; and different plant growth regulators or organic substances were added to find out the most suitable media for inoculation and for development of callus, root and shoot. Different types of cultures were developed and single shoots or multiple shoots as well as compact and friable callus were obtained from different explant sources. Zeatin added to MS medium gave the best result for shoot and root induction and the addition of banana showed promising results for shoot maturation in culture. The overall trials are described in this paper.

The autecological study of kapur tree ( Dryobalanops lanceolata Burck) has been conducted in the Kinarum Forest of Tabalong and the Tampaan Forest of Balangan, South Kalimantan. This study aims to obtain the latest information about the existence of D. lanceolata and its habitat conditions. This study has been conducted in both forest areas by sampling using the pathway method. The total area observed was 0.6 ha in the Kinarum Forest and 0.2 ha in the Tampaan Forest. The results showed that D. lanceolata grew better in Kinarum Forest than Tampaan Forest. Tree of D. lanceolata is the most dominant in Kinarum Forest with INP = 46.26%, while in Tampaan Forest is ranked fourth (INP = 21.28%); the volume of D. lanceolata stands in Kinarum Forest (2910.55 m 3 /ha) is greater than in Tampaan Forest (90.55 m 3 /ha). The IS values for tree level are 0.55 (17 species), pole 0.18 (four species), saplings 0.08 (three species) and seedlings 0.10 (two species). The correlation value between the presence of D. lanceolata and the environmental variables was very weak to weak (<0.399). In general, D. lanceolata grows in a somewhat steep, steep, to very steep terrain with slopes heading west (-35 o to +15 o ), sandy loam soil texture, brown (7.5 YR 4/6) to brown or yellowish red (10 YR 5/6), pH 5.8-6.5, C/N ratio 13 18, air temperature 30.7 + 1.36 o C, air humidity 55 + 18%, light intensity 1954, 64 + 2170.98 lux, and percent canopy 28.35 + 11.39%.

Grammatophyllum speciosum Blume is one of the threatened orchid species due to over exploitation and forest degradation, therefore this species needs to be conserved. One of the conservation efforts is to propagate through synthetic seed using sodium alginate as encapsulation matrix and calcium chloride as complexing solution. This research was conducted to obtain an optimal concentration of sodium alginate and calcium chloride for synthetic seeds forming and the best storage condition (temperature and storage period). Protocorm was used as the propagule of the synthetic seed. Sodium alginate 4% produced uniform and isodiametric shape, while calcium chloride 75 mM generated rigid and clear matrix wall to ensure the protection of propagule during storage. Extending storage period resulted in lower germination percentage. The encapsulated protocorms of K3-K6 which stored at 4 o C up to 4 weeks still give the highest germination rate (93,33-100%). The synthetic seed of K2-K6 stored at 25 o C was viable up to 16 weeks with the highest germination rate 93,33-100% and also has better regrowth than those having been stored at 4 o C

Recording the existing diversity of an area is necessary to be done before the area is developed into a botanic garden. This study aims to determine the composition, structure and community type of Sampit Botanic Gardens to serve as the basis for determining its land use zoning and collection themes. A vegetation analysis was conducted using plot method that was placed in five locations (each 500 m 2 ). All of the trees, sapling and ground vegetation were enumerated. A total of 40 families, 64 genera and 85 species were found within total plot of 2500 m 2 . The results shows that there are 30 species of trees, 36 species of sapling, and 43 species of ground vegetation. The highest number of trees is found in plot Lb-C (19 species), but plot Lb-D has the highest diversity and evenness indices. The three plots in dryland are dominated by Imperata cylindrica (Lk- A), Acacia mangium (Lk-B) and Melaleuca leucadendra (Lk-E), while the two plots in the wetlands are dominated by Tetramerista glabra (Lb-C) and Palaquium calophyllum (Lb-D). The highest tree density in plot Lb-C (800 trees/ha), while the highest basal area in Lb-D (24.1 m²/ha). Base on NMDS ordination, the vegetation tends to form three communities, namely: 1) Imperata cylindrica - Dicranopteris linearis , 2) Melaleuca leucadendra - Acacia mangium , and 3) Palaquium calophyllum - Tetramerista glabra . Community of P. calophyllum - T. glabra should be maintained as in situ conservation areas. I. cylindrica - D. linearis community can be used for physical buildings, thematic parks, nursery and plants development. The collection zone should be placed at the M. leucadendra - A. mangium community, and in part on the P. calophyllum - T. glabra and I. cylindrica - D. linearis communities. Collection theme for Sampit Botanic Garden suggested is ex situ conservation for heath forest.
在将一个地区发展成植物园之前,有必要对该地区现有的多样性进行记录。本研究旨在确定Sampit植物园的组成、结构和群落类型,作为确定其土地利用分区和收集主题的基础。采用样地法在五个地点(每个500平方米)进行植被分析。所有的树木、树苗和地面植被都被列举了出来。在2500 m2的样地内共发现40科64属85种。结果表明,该区有乔木30种,幼树36种,地面植被43种。样地Lb-C的树木数量最多(19种),样地Lb-D的多样性和均匀度指数最高。旱地3个样地以白茅(Lk- A)、洋槐(Lk- b)和千层树(Lk- e)为主,湿地2个样地以光四叶草(Lb-C)和calophyllum (Lb-D)为主。Lb-C样地乔木密度最高(800株/ha), Lb-D样地基材面积最高(24.1 m²/ha)。基于NMDS排序,植被倾向于形成3个群落,即:1)白茅-双翅翅果群落,2)白树千层- mangium, 3) calaquium calophyllum - Tetramerista glabra。在原有的保护区内,应保持花椒-光斑柽柳群落。白茅群落可用于实体建筑、主题公园、苗圃和植物开发。采集区应设在leucadendra - A. mangium群落,部分设在calophyllum - T. glabra和I.圆柱- D. linearis群落。建议桑皮植物园的收藏主题为迁地保护。

The research aims to obtain information about potential species and carbon content of mangrove forests in the Karangsong, Indramayu, West Java. The plots were made in three places consisting of 12 samples of 10 x 10 m for tree inventory, saplings and seedlings with 20 m plot spacing. The results showed that in the mangrove forest of 15.9 ha, eight species were found. The dominant species for tree and sapling stages are Avicennia marina Blume with IVI 279.74% and 156.03%, respectively. The dominant species for seedling stage is Rhizophora stylosa Griff. with IVI 21.32%. Regeneration in mangrove forests is quite good.

Homalomena bellula Schott termasuk ke dalam suku Araceae. Jenis ini merupakan salah satu jenis lokal endemik dan langka (kategori vulnerable menurut kiteria IUCN). Selain itu H. bellula merupakan jenis yang unik karena memiliki pola pertumbuhan tunas ( shoot architecture ) yang berbeda dengan jenis-jenis Homalomena lainnya yang ada di Pulau Jawa. Pola pertumbuhan tunas H. bellula menyerupai pola pertumbuhan tunas pada jahe-jahean atau menyerupai model Tomlinson. Keberadaan H. bellula di alam hampir tidak pernah ditemukan lagi sejak pertama kali ditemukan dan dipublikasikan oleh Schott pada tahun 1863 di Pulau Jawa. Penelitian ini bertujuan untuk mengetahui keberadaan jenis ini di habitat aslinya, pola pertumbuhan tunas dan usaha konservasinya. Kegiatan yang dilakukan adalah penelitian di lapang, studi spesimen herbarium dan spesimen hidup. Berdasarkan data dari spesimen tipe, jenis ini ditemukan di Gunung Halimun, Jawa Barat. Dari hasil penelusuran keberadaan jenis H. bellula di Pulau Jawa, ditemukan lokasi baru penyebaran jenis ini yaitu di areal Pancuran Tujuh di kaki Gunung Slamet, Baturraden, Jawa Tengah. Keberadaan jenis ini di habitatnya cukup mengkhawatirkan dan diperlukan upaya konservasi eks situ dalam upaya mendukung kelestariannya.

Amorphophallus titanum (Becc.) Becc. ex. Arcang belongs to Araceae family. The genus Amorphophallus consists of 220 species which is distributed in tropical and subtropical countries worldwide. About 26 species have been recorded in Indonesia or 11.6 % of the total Amorphophallus in the world. Sumatera Island has the highest endemic Amorphophallus species, encompasses 11 species, of which seven species are endemic, such as A. titanum . The presence of A. titanum in its natural habitat has been alarmed. The lowland forests of Sumatera have been widely converted into agricultural and housing, thus may affect the rate of extinction of A. titanum in nature. The aim of this study is to provide the distribution map of A titanum in Lampung. Several sites in national parks, protected forests and community forests were observed for the research. This research was carried out from 2011 to 2016 using explorative method. The results showed that less than 10 mature individuals of A. titanum were found in each location. This indicates that this species is vulnerable, or even leading to extinction in future if not immediately protected. The result of this research will proposed for reassessing the conservation status of A. titanum . All specimens of A. titanum collected from the forests are cultivated in Liwa Botanic Garden and Bogor Botanic Garden as an ex situ conservation action for the species.
