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.

Cabai Merah (Capsicum annuum L.) biasanya ditanam di pembibitan sebelum dipindahkan ke lahan. Informasi mengenai lingkungan optimal, termasuk intensitas cahaya, penting untuk memproduksi bibit cabai berkualitas. Penelitian bertujuan mengetahui pengaruh intensitas cahaya, berdasarkan jenis atap persemaian (paranet kerapatan 25%, 50%, dan 75%, kaca, dan fiberglass), terhadap perkecambahan dan pertumbuhan bibit cabai cv. Landung. Penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan empat ulangan. Hasil penelitian menunjukkan intensitas cahaya mempengaruhi perkecambahan dan pertumbuhan bibit cabai merah secara keseluruhan. Benih yang memperoleh intensitas cahaya lebih tinggi, yakni di bawah atap kaca (13.876,67 lux) dan atap fiberglass (16.268,89 lux) berkecambah lebih awal dan lebih seragam, dan menghasilkan persentase perkecambahan akhir lebih tinggi (97% dan 95%) dibandingkan benih yang memperoleh intensitas cahaya lebih rendah (atap paranet dengan kerapatan 25%, 50%, dan 75%), masing-masing sebesar 90%, 80,5%, dan 73,2%. Pertumbuhan bibit cabai merah di bawah atap kaca dan fiberglass lebih vigor sehingga menghasilkan kecepatan pertumbuhan (R) lebih tinggi (7,25 dan 7,49) dibandingkan semua perlakuan paranet (7,74, 7,74, dan 7,62). Bahan atap persemaian perlu dipertimbangkan sebab mempengaruhi perkecambahan dan pertumbuhan bibit cabai dengan mempengaruhi intensitas cahaya, seperti ditunjukkan oleh penelitian ini.

Marine algae is a biological source that is rich in bioactive activity. Marine algae is an important source of macronutrients, especially proteins and lipids, as well as micronutrients such as vitamins and minerals along with dietary fiber and other minoritarian constituents such as polyphenols. This study aimed to determine the antioxidant of hydrolysate protein of Sargassum sp. as. The work method was started by collecting Sargassum sp. in the intertidal zone of the South Coast of Gunungkidul, Yogyakarta and then brought to the laboratory for extraction. Protein hydrolysate was obtained by protein extraction using phosphate buffer and triRNA kit. Several buffers was used to optimize the extraction, namely PBS buffer, Tris HCl buffer and plant extraction buffer The protein obtained were evaluated in the SDS-PAGE electrophoresis. The isolated protein subjected for the trypsin digestion to obtain the hydrolysate protein then followed by antioxidant assays using DPPH test. Data analysis was carried out using ANOVA statistics for the antioxidant test. Several ratios of trypsin and protein are used to find the optimal ratio to produce protein hydrolysate. From the result it was observed that the best buffer solvent to use was Tris HCl buffer for the isolation of Sargassum sp. This can affect the protein profile of the Sargassum sp protein hydrolysate. by producing higher protein precipitates than other buffer types.

Castanopsis argentea is a potential souce of natural antibiotics that has not been studied much. The purpose of this study was to analyze the antibacterial activity and study the content of secondary metabolites from leaves and twigs extract of Castanopsis argentea against Escherichia coli and Staphylococcus aureus bacteria. This study used the paper disk method to see antibacterial activity. Antibacterial activiy was indicated by the formation of a clear zone around the dic paper. Samples were made into three treatments, namely the concentration of 20 mg/ml; 40 mg/ml; and 80 mg/ml. the solvent used was selected based on the level of polarity namely ethyl acetate, 70% ethanol, and aquades. The results of the antibacterial activity test showed that the extract with the most potential to inhibit bacterial growth was ethyl acetate twig extract at a concentration of 80 mg/ml with an average diameter of 6mm for Escherichia coli bacteria and 8.67 mm for Staphylococcus aureus bacteria. The compounds identified in the ethyl acetate twig extract are terpenoids, phenolics, and flavonoids. The results of profiling using UV-Vis spectrophotometry showed that the maximum absorption of terpenoids, flavonoids, and phenolics compounds was found in the wavelength range of 300-600 nm. The secondary metabolite compounds contained in the leaf and twig extracts of Castanopsi argentea make this species a potential natural antibacterial.

Artificial light at night (ALAN) can significantly affect plant physiology, as many physiological processes are light-dependent. However, studies investigating the specific effects of ALAN on plants remain limited. This study aimed to assess the impact of ALAN on the growth and metabolite composition of bisbul (Diospyros discolor Willd.). The experiment was conducted in Nursery 2 of the Bogor Botanical Gardens over 12 months. A split-plot factorial design was employed with three replications, each consisting of three one-year-old seedlings. The main plots were assigned to light color treatments (control, red, green, and blue), subplots to light intensity levels (control, high, and low), and sub-subplots to illumination durations (0, 1, 6, or 12 hours) applied for 0, 2, or 7 nights/week. ALAN treatments were administered continuously for one year. The results indicated that blue light significantly increased leaf senescence, particularly under BH-6(2), BH-12(2), and BH-12(7) treatments. Conversely, high-intensity red light reduced plant height, shoot dry mass, photosynthetic rate, and chlorophyll content. Metabolite profiling revealed decreased levels of secondary metabolites such as caffeic acid and catechin, while compounds such as nicotinamide, L-proline, linolenic acid, and coumarin increased. These findings suggest that prolonged exposure (6-12 hours) to high-intensity red or blue light can disrupt circadian rhythms and impair physiological functions.
