Safety perception is the most important part of people's choice in determining tourist sites. Standing trees that are prone to falling are very dangerous for both visitors and employees. Standing tree with decay wood inside is often the cause of tree failure. Therefore, there is a need for research examining the risk of collection and non-collection trees in Bali Botanical Garden. Tree risk checks were carried out using the Tree Risk Assessment method from the International Society of Arboriculture (ISA), which has been modified. The result of this research gives valuable information for the manager to determine tree handling to minimize tree risk.
Momordica charantia merupakan tumbuhan herba merambat, yang dikenal masyarakat Indonesia dengan nama “pare”. Tumbuhan ini secara umum dimanfaatkan masyarakat Bali untuk membuat loloh (minuman herbal tradisional Bali) untuk meredakan panas dalam, mengobati limuh dan diabetes. Penelitian ini bertujuan untuk mengetahui pemanfaatan M. charantia oleh masyarakat Bali serta aktivitas farmakologinya. Metode yang digunakan dalam pengumpulan data adalah dengan menggunakan scientific databases, seperti google scholar, science direct, portal scopus, dan springer. Data yang diperoleh selanjutnya dianalisis dengan pendekatan deskriptif kualitatif. Hasil menunjukkan bahwa masyarakat Bali menggunakan M. charantia sebagai obat tradisional pada beberapa kondisi yaitu limuh (pingsan), barah/ beteg (bengkak), nyeri, dan cacar. M. charantia mengandung aktivitas farmakologi, seperti antidiabetes melitus, antikanker, antibakteri, antifertilitas, antivirus, anti-ulcer, antelminitik, dan antimalaria.
Paphiopedilum javanicum (Reinw. ex Lindl.) Pfitzer known as slipper orchid is an endemic terrestrial orchid from Indonesia. This orchid is threatened with extinction and listed under CITES Appendix I. In-vitro propagation of P. javanicum has been done in Bali Botanic Garden (BBG) for last six years but acclimatization stage has not given satisfied result. The purpose of this study was to know the ef-fect of liquid fertilizer on vegetative growth of P. javanicum planlet during acclimatization stage. Beyonic StarTmik liquid fertilizer ap-plied by five different doses considered as treatment of 0, 10, 20, 30 and 40 mL. They were 10 planlets for each treatment considered as replication. In this research we observe vegetative growth of P. ja-vanicum by quantitative and qualitative parameter. Quantitative data were analysis by ANOVA. Result showed, high percentage of planlet survival was observed of 98% and liquid fertilizer dose for 30 mL gave the optimal vegetative growth of P. javanicum planlet with aver-age height of 2.2 cm and leaves number of 13 pieces. There were no differences on qualitative parameter in all treatment that all leaves color was dark green and leaves tessellation appearance was obvious
Orchid roots have vital functions for water absorption, nutrient uptake, a place of symbiosis with mycorrhizal fungi, adaptation, and survival. The aim of the present study was to investigate root traits in terms of root morphological, anatomical, and mycorrhizal features of a terrestrial orchid, Peristylus goodyeroides in relation to an ecological significance of root traits in survival of seedlings, juveniles, and adults of the orchid. Results showed that some morphological characters (root length and depth), anatomical features (cortical cell size, xylem number and diameter), and mycorrhizal features (peloton size and number) were significantly different between seedlings, juveniles, and adults. In relation to root functional traits, lowest root length, depth, xylem number and diameter, peloton size and number in seedlings can be associated with low capacity in water and nutrient acquisition that might explain low survival of seedlings relative to juveniles and adults. Present study has implication for orchid conservation suggesting high attention in low survival rate of seedlings related to specificity in some of their morphological, anatomical, and mycorrhizal features which can be associated with low capacity in water and nutrient acquisition. It is vital to ensure water availability for seedlings, particularly, during dry seasons to decrease high mortality of seedlings as such high mortality can have adverse impacts on long-term survival of the orchid population.
East Nusa Tenggara located in the Wallacea area that has many endemic species. However, the existence of germplasm diversity in this area has been threatened due to landscape changes and deforestation. The research was conducted to identify floristic composition in Sikka forest area. This research also aimed to compare that plant composition in Sikka forest area on each of the different altitudes, including their diversity richness and environmental factors. Two sampling methods were used, which are Point-Centered Quarter (PCQ) method that applied for trees and nested sampling method 5x5 m2 for sapling and 2x2 m2 for ground cover. Measured parameters were Relative Density (RD), Relative Frequency (RF), Relative Coverage/dominance (RC), Important Value Index (IVI), Diversity Index (H'), and Jaccard Similarity Index (J’). Research results showed that the diversity index of each region was relatively low. Plant composition of tree, sapling, and groundcover in three different altitudes was quite different. This result indicates that the plant composition in the Sikka, East Nusa Tenggara is very diverse. The temperature and relative humidity in each altitude area observed was significantly different. One of the endemic species of Flores Island, Eucalyptus urophylla, was only found at 500-700 m asl. There are very limited research on the vegetation diversity held in Flores, East Nusa Tenggara. This research can be the basic for further research in order to explore the potential diversity of flora in this area.
Mayoritas masyarakat sekitar kawasan hutan danau Buyan dan Tamblingan memeluk agama Hindu. Masyarakat memanfaatkan tumbuhan dalam berbagai kepentingan, sehingga mereka memiliki peran penting untuk menjaga dan melestarikan keanekaragaman tumbuhan di sekitarnya. Penelitian ini bertujuan untuk mengetahui pemanfaatan tumbuhan oleh masyarakat Bali di sekitar kawasan hutan danau Buyan dan Tamblingan. Metode dalam penelitian ini adalah wawancara. Hasil menunjukkan bahwa terdapat 181 jenis tumbuhan yang dimanfaatkan oleh masyarakat untuk 11 jenis tujuan pemanfaatan.
Standing trees has a higher risk regarding structural damage that can cause trees or parts of trees to fail. Meanwhile, Bali Botanic Garden is located in a highland area that periodically gets natural disasters such as heavy wind. However, the information on tree stability is little known. Therefore, tree stability at Bali Botanic Garden was assessed using tree slenderness coefficient (SC) as an indicator. Purposive sampling technique was adopted for locations which highly visited. A total of 624 trees with dbh>40 cm were examined as samples. Trees were classified based on their SC as high (>80), moderate (SC:70-80), low (SC<70). Data were analyzed using descriptive and correlation analysis. Tree slenderness coefficient at Bali Botanic Garden classified as low (609 specimens), medium (11 specimens), and high (4 specimens). Trees with the high category were three individuals of Bischofia javanica Blume (SC=82.76, 83.69, and 89.63) and a Syzygium polyanthum (Wight) Walp. (SC=116.13). Trees with high SC had a higher susceptibility to wind-induced damage. There was a negative correlation between SC and others tree parameters except for tree height (r=0.44). Hence appropriate silvicultural treatment like thinning is recommended to enhance better tree development and minimize tree risk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
