Abstract

The Bogor Botanical Garden (BBG) is a pivotal center for plant research and conservation, boasting a diverse collection of over 12,000 individual plants spanning various species. However, among the plant collections at BBG, some of them have the potential to be invasive. Therefore, this study aimed to uncover the plant collections at BBG with invasive potential and analyze the distribution of one of the most dominant collections, Epipremnum pinnatum (L.) Engl. The method employed in this research involved a literature review to identify which plant collections have invasive potential and a vegetation analysis on the distribution of E. pinnatum within BBG. Additionally, ANOVA analysis and regression models were employed to explore the relationship between environmental factors and E. pinnatum abundance. Results revealed that BBG hosted 78 potentially invasive plant species, with E. pinnatum comprising 28 individuals. Spatial analysis indicates a clustered distribution of E. pinnatum, influenced by seed dispersal mechanisms, environmental factors, and biotic interactions. Correlation analysis links soil pH, soil moisture, and canopy cover to E. pinnatum distribution. Canopy cover demonstrates a significant positive correlation with E. pinnatum abundance, suggesting its importance in providing favorable microclimates for growth. Regression analysis further supports canopy cover as a predictor of E. pinnatum presence. However, while a strong statistical association was observed, causal relationships require further investigation. This study underscores the complexity of ecological dynamics in BBG and emphasizes the need for comprehensive research to define underlying mechanisms driving plant distributions and interactions.

Abstract

Program penyelamatan dan pengembalian tumbuhan langka yang terancam punah telah banyak dilakukan saat ini. Upaya ini dilakukan guna mengembalikan populasi tumbuhan yang hampir atau telah punah ke habitat aslinya. Namun, pengembangan pendekatan kuantitatif maupun permodelan dalam upaya reintroduksi tumbuhan langka terancam kepunahan belum banyak dilakukan. Penelitian ini bertujuan untuk mengumpulkan informasi mengenai metodologi kuantitatif dan permodelan yang dapat digunakan dalam mendukung program reintroduksi tumbuhan langka yang terancam punah. Metode yang digunakan adalah mengumpulkan berbagai informasi dari berbagai sumber literatur mengenai pendekatan permodelan yang dapat digunakan dalam program reintroduksi tumbuhan langka. Beberapa pendekatan permodelan yang dapat digunakan dalam mendukung program reintroduksi tumbuhan langka yaitu model kesesuaian habitat, model autekologi, model dinamika populasi, model dispersal dan model analisis keterancaman habitat. Model tersebut telah tersedia dalam bentuk "library" atau "package" yang dikembangkan dalam bahasa pemrograman R dan Python. Kedua bahasa pemrograman tersebut telah banyak digunakan dalam penelitian ekologi dan konservasi. Pengembangan permodelan tersebut diharapkan mampu menjadi informasi penting dan acuan dalam program reintroduksi tumbuhan langka terancam kepunahan di Indonesia.

Abstract

The IUCN red listed Pinanga javana Blume, also known as Javanese Pinang, as a protected and threatened species that is endemic to Java island, Indonesia. This research focused on study of the germination and growth process of P. javana seedlings using four types of planting media: cocopeat, husks, sand, and sawdust. The results showed that P. javana seed water content slowly decreased from 33.96% to 24.45% during the storage period from day 0 to day 21. The planting medium had a significant influence on the germination rate, with sand exhibiting the highest value (2.34) and husks providing the best seedling growth. Cocopeat had the highest moisture level (90%), while sand generated the lowest moisture level. The pH of all media was within the normal range (6-7), which supports optimal germination. The analysis of various parameters concluded that sand was the optimal planting medium for P. javana in this study. Keywords: germination, planting media, Pinanga javana, viability, water content
