Mount Seblat, as part a of Kerinci Seblat National Park (KSNP), is a pristine and natural mountain, particularly from disturbances and destructions by human activities. Nevertheless, the richness of biological resources especially plant diversity.in this area has not been more explored. The purpose of this study was to conduct an inventory of plant diversity and to determine the plant species composition. The inventory activities were conducted by plants collection along the ascent route. The results were then be maintained through ex situ conservation method in Cibodas Botanical Garden (CBG). The study was conducted by exploratory method, from Seblat Ulu Village (641 m asl) up to altitude of 1,037 m asl. There were 18 points of plant sample observation with an area of 5 x 5 square meters per point. Plant collection obtained 380 specimens. Five groups of most collected plants were Lauraceae (18 species), Rubiaceae (8 species), Anacardiaceae (6 species), Annonaceae (5 species), and Fagaceae (4 species). In order to enrich the plants collection as well as conduct the ex situ conservation effort, plants from Orchidaceae were also collected which resulted in 33 species. These results were an important initial inventory of plant diversity of Mount Seblat, considering that there was no record as well as very limited current information. When the environment disturbance tends to increase, this information may act as a reference and an initial database to develop plants conservation effort and strategy in the future.

Plants, especially species of trees, have an important role in modifying the microclimate, particularly temperature and humidity. This study was aimed to evaluate the effectiveness of trees in modifying the temperature and humidity and their interaction in forming the microclimate amenities. There are two methods in the study, first by comparing the temperature and humidity between open space free of shading and under the shade of tree canopies. Sample trees used as many as three trees which are Bunga Sapu tangan (Maniltoa schefferi), Bauhinia (Bauhinia purpurea), and Tanjung (Mimusops elengi). The second method is by making the observation grid which sized 50 x 50 meters that is divided into grids of smaller-sized grid of 10 x 10 meters, then analyzed the air temperature to make the isotherm lines. The study shows that trees can significantly lower the temperature (2.9-7.4 OC) and increase the humidity (0.1-3.9%). Nevertheless, the tree has a limited role and canâ€™t stand alone in order to form microclimate amenity in the environment (THI> 26).

The level of service quality delivered to the customers on a tourism business might be represented by a satisfaction index. A higher index means that the service is more satisfying and eventually might attract more customers. However, whether the increasing number of customers always reflect a better service quality? This study was aimed to analyze the level of satisfaction and its correlation to the number of visitors to Cibodas Botanic Gardens. The satisfaction index was analyzed based on nine criteria, complying with the regulation of the Minister of State Apparatus Utilization and Bureaucratic Reform, Republic of Indonesia. The analysis started by distributing the questionnaires, which resulted in 1,321 respondents from 2017 to 2019. The number of visitors was obtained by inventoried the number of the sold tickets monthly. Pearson test (r) was used to examine the correlation between the satisfaction index and the number of visitors, and a t-test to evaluate the level of significance (α = 0.05). The findings showed that the index from 2017 to 2019 was relatively stable: 80.8, 80.15, and 80.93 (scale of 25 to 100), respectively. On the other side, the number of visitors tends to rise each year by 24% to 26% instead. The test showed that the correlation is positive but weak (r = 0.236) with no significance. These results provide an overview description and for operators' consideration to manage the site in their policies. The efforts not only focus on attracting more visitors but also on enhancing the quality of the services.JEL Classification: Z30; Z32; Z38

Abstract: The threats to the plant biodiversity become more advance along with rapid degradation of the natural habitat. Plants preservation needs accompaniment between in-situ and ex-situ conservation altogether. The ex-situ plant conservation plays more important roles in order to help conserve threatened plant species. Cibodas Botanic Garden (CBG) is a government institution which has the main assignment on ex-situ plant conservation, especially tropical mountainous plants. In the last decade, CBG has conducted exploration and plants collection in order to retrieve them from the destructive pressures in their habitat. This study aimed to asses the CBGÃ¢â¬â¢s contribution to ex-situ plant conservation through the addition number of planted plants and to describe the important value to conservation. The study conducted through a quantitative descriptive method, based on data inventory of the newly planted plant in the garden from 2008 to 2018. This also assessed the increasing collection of each year and descriptively explaining the background data, species variety, and their conservation status. The results described that the additional number was 473 specimens and the average increase was 43 specimens per-year. These originated from exploration and plants collection 248 specimens, donation 217 specimens, self-propagation seven specimens, and one specimen from seeds exchange. The most planted was Nepenthaceae with 84 specimens, secondly Phillantaceae with 21 specimens, and Lauraceae 15 specimens. There were 116 species (152 specimens) which have conservation status. These expected to be a comprehensive description of the CBGÃ¢â¬â¢s plant collection and meaningful for the conservation efforts in general.Keywords: ex-situ plant conservation; garden collection; Cibodas Botanic Garden (CBG)

Abstract: One of the botanic gardens businesses is socializing cultivated plants from the garden to be further utilized, especially for reforestation (and other conservation purposes), research and educational purposes. This socialization can be conducted through seeds exchange and plant (and parts) that transferred for various users. Cibodas Botanic Gardens (CBG), as one of the Indonesian botanic gardens, is also conducted this activity. Plant materials and so the data needed for these purposes are recorded in the material(s) transfer agreement (MTA). The study aimed to analyze the number, type, and species of transferred plant materials and the data, the background of the applicants and for what purpose of the materials is needed based on MTAÃ¢â¬â¢s documents. This study conducted through a quantitative descriptive method based on the materials transferred from 2013 to 2018. The results described that, for six years, the number of MTA was 86 documents, with 81 applicants. The applicants from local were 92.6% and foreign such as from China, Netherlands and Japan were 7.4%. For six last years, the transferred materials included 1,205 in the form of living plants, 201 specimens in form of herbarium, 8,605 specimens in the form of seeds, many thousands various unit of part of plant, plant propagation unit and other plant materials (i.e. mycorrhiza, fungi/ lichen/ moss, rhizoid and thallus, and ascoma), and 63 unit in the form of data and other information. The results expected to be able to describe the contribution range of CBG, especially in ex-situ plant conservation and the data, both on the local and international scale.Keywords: plant materials; material(s) transfer agreement (MTA); ex-situ plant conservation; Cibodas Botanic Gardens (CBG)

Despite the routinely conducted treatment and maintenance of garden plant collection, the monthly mortality figures of the Cibodas Botanic Gardens (CBG) plant collections remain significant. It is presumed that the microclimate has a crucial influence on plant survivorship in the field. This study aimed to analyze the effect of microclimate conditions on the mortality rate of the CBG plant collection. The study was conducted by correlating the number of mortal plants with CBG monthly microclimatic conditions from 2017 to 2018. The analyzed microclimate parameters were temperature, relative humidity, precipitation, wind velocity, and solar radiation. The multiple regression modeling, t-test, and Pearson correlation test (r) were utilized to measure the level of significance of the correlation (α = 0.05). The findings were shown that the maximum wind velocity was the primary unit correlated to the number of mortality. The correlation was strong positive (r = 68.8%), and significant (p-value α). We suggested anticipating the disadvantages influences of strong wind supported by other extreme microclimate units, such as heavy rain. These events frequently caused high damage to the tree and other plant collections. These are expected to be taken into a consideration by the CBG operator and management in order to forecast and mitigate the risks of future plant collection losses.

A botanical exploration and collection were already conducted in March 2019 in Pasir Banteng and Pasir Pogor, Mount Gede Pangrango National Park, Indonesia, by a staff team from Cibodas Botanic Gardens (CBG). The following steps are to ensure these plants will be vigorous and survive in the nursery, which will later be ready to be planted and displayed as a garden collection. This study aimed to describe a series of treatments and management of these collections, analyze the survivorship level in the nursery, and record which seedlings were successfully planted in the garden. We explained the plant mainteÂnance used a qualitatively-descriptively method; the survivorship level was measured based on the proportional numbers of the survived individuals; the planted seedlings in the garden were recorded from the field observation. The findings showed that in the first three months of maintenance, seedlings occurred a large amount of mortality. Next, from June 2019 to August 2020, the seedlings performed good development with no mortaliÂty reported. In September 2020, as many as 13 specimens experienced mortality. At the end of December 2020, the total crude mortality was 41 specimens, and the survivorship level was 75.15%. All the orchid specimens have been planted as the garden collecÂtions
