Melon (Cucumis melo L.) is a plant that has economic value and has been cultivated in several areas of Indonesia with intensive fertilization. The mineral nutrient that is expected to improve the quality of melon growth and fruit is silica. The aim of the research was to improve the growth and melon fruit quality by addition of silica fertilizer. The treatments in this experiment were the application of silica (Novelgro, water soluble) which was carried out on melon plants with silica concentrations of 0.67; 1.33 ppm; and control (without silica). The results showed that silica increased the plant height, leaf area, and diameter of melon fruit. Melon plant with silica treatment of 1.33 ppm had silica content in the high category (>4% Si) which was 5.31% in the skin of the fruit. Moreover, the addition of silica can prolong the fruit storage period in room temperature compared to control.

High methane oxidation activity of local isolated methanotrophic bacteria have a potent as methane gases reducing agent while combined with nitrogen fixing bacteria as paddy biofertilizer. The aim of the research was to evaluate the effectiveness of the bacteria as methane gases reducing agent and biofertilizer in paddy plantation. The research was arranged in a completely randomized design consisted of fertilizer types and watering system treatments with four replicates. The research showed that paddy shoot length was not affected by the treatment. On the other hand, both plant freshand dry weight, as well as the number of productive tiller were affected by interaction of fertilizer types and watering system. Fertilizer types affected grain per panicle and methane flux after fertilization. In the end of paddy vegetative stage, bacterial fertilizers were capable to reduce methane emission in different rate. The different result in methane flux was likely due to the interaction between soil local microorganisms and soil chemical component.

Mutualistic plant-microbe interaction can increase the availability or absorption of nutrients and affect plant metabolism. Metabolomics is the study of all metabolites contained in living beings at a specific time. This research aims to study the effect of metanotrophic bacteria (BGM 9 isolate) and nitrogen-fixing bacteria (ITJ 7 isolate) on rice plant growth and reveal the information about metabolites produced by rice plant interacting with the bacteria. Three rice plant varieties (Ciherang, Hawara Bunar, and IR64) were grown on liquid media (Yoshida solution) and were inoculated with the bacteria five weeks after planting. Metabolites in the liquid media were detected seven days after inoculation using Liquid Chromatography-Mass Spectrometry and analyzed using MassLynx v4.1. The results showed that the bacterial inoculation had significant effect on rice growth. Chromatograms resulted from LC-MS showed there are 34 unique peaks from Ciherang, 21 unique peaks from Hawara Bunar, and 30 unique peaks from IR64. The unique peaks in each variety were affected by the bacteria inoculation treatments.

Oil palm requires sufficient water for optimal growth. However, oil palm plantations in Indonesia face the challenge of global climate change, which causes increased temperatures and unpredictable rainy seasons. The research aimed to analyze oil palm accessions from Jambi that are tolerant to drought based on plant morphophysiological characteristics and metabolite profile. The experiment was conducted in the greenhouse using a factorial randomized block design. Five oil palm accessions were evaluated in this study, i.e., Muara Jambi (MJ), Tebo (TB), Tanjung Jabung Barat (TJB), Merangin (MR), and Simalungun (SM). Seedlings were planted in pots containing 20 kg of soil and acclimatized for 14 days before treatment. Drought treatments were carried out for two, four, and six weeks. Observations were made on growth, physiological, and metabolite changes at the end of each drought period. The study showed that the SM accession exhibited a higher photosynthetic rate and fresh and dry biomass than the other accessions. However, the content of proline and MDA increased significantly in oil palm throughout the drought periods. Metabolomic profiling revealed a significant increase in 13 metabolites under drought stress, i.e., citramalate, L-tyrosine, ferulate, and 3-4-dihydroxybenzoate were the four most prevalent metabolites in the leaf. The root produced more L-proline, aspartate, aconitate, kaempferol-3-o-pentoside, oxoadipate, citrate, L-phenylalanine, maltose, phenylacetic acid, and citramalate. These metabolites have roles in plant metabolic pathways such as valine, leucine, and isoleucine biosynthesis, phenylpropanoid biosynthesis, arginine and proline metabolism, citrate cycle (TCA cycle), lysine biosynthesis, phenylalanine metabolism, and starch and sucrose metabolism.

White turmeric (Curcuma zedoaria) contains bioactive compounds with antibacterial and cytotoxic potential; however, the quantity of these compounds and their biological activity remain relatively low. Fermentation can enhance these properties by promoting microbial bioconversion. This study evaluated the total flavonoid content as well as antibacterial and cytotoxic activities of C. zedoaria rhizomes fermented using a Symbiotic Culture of Bacteria and Yeast (SCOBY). Antibacterial activity was evaluated against Escherichia coli and Staphylococcus aureus using the disk diffusion method, while cytotoxic activity was analyzed using the Brine Shrimp Lethality Test (BSLT). The results showed that fermentation increased the total flavonoid content by 64% and substantially improved antibacterial performance, producing inhibition zones of 13.7±0.7 mm for E. coli and 12.8±0.4 mm for S. aureus, more than double those of the non-fermented white turmeric. Cytotoxic activity also increased, as indicated by a lower LC50 value (145.3 µg/ml) compared to the non-fermented white turmeric (1,381.8 µg/ml). Overall, the findings demonstrate that fermentation significantly enhances the antibacterial and cytotoxic activities of white turmeric. Keywords: bioactivity enhancement, fermentation, functional beverage, SCOBY, white turmeric

Abstract. Sutopo S, Rahman DA, Gustiawan I, Giri MS, Muttaqin M, Akbar MS. 2025. Habitat suitability and distribution of Sumatran serow (Capricornis sumatraensis) in a Leuser ecosystem, Indonesia. Biodiversitas 26: 3875-3885. Determining the distribution of species and suitable habitats is a fundamental part of planning for the protection of key species. Mount Leuser National Park (MLNP), Indonesia, is habitat to the Sumatran serow (Capricornis sumatraensis sumatraensis), an endangered ungulate species. Habitat loss due to deforestation for agriculture, oil palm plantations, illegal hunting, and illegal trade in body parts are factors contributing to the increasing pressure on this species in its natural habitat. Therefore, this study aims to model the distribution of the Sumatran serow and identify priority conservation zones based on habitat suitability models. We conducted ensemble modelling implemented in the R package ‘ENMTML’ using 3 modelling techniques (MaxEnt, Random Forest, and Boosted Regression Tree) and an ensemble model. We combined 282 Sumatran serow occurrence points with 9 climate, topography, vegetation, and anthropogenic variables. The Random Forest model performed best among the three models in predicting Sumatran serow habitat, with an AUC value of 0.89 and TSS of 0.62. The Random Forest model predicts a larger area with low habitat suitability, covering 74% (610,520 ha) of the total area, with moderate habitat suitability covering 16% (131,090 ha) and high habitat suitability covering only 10% (78,139 ha) of the Sumatran serow distribution across the study area. Our model can help identify potential protection areas for this species to support its conservation. This has implications for knowledge about the current distribution and suitable habitat for Sumatran serow. Conservation efforts can be focused more effectively on core zones, particularly in Section III, Blangkejeren, and Section IV, Badar. By utilising the results of the habitat suitability model for several actions such as evaluating MLNP zoning, prioritising monitoring areas, considering corridors for connectivity, and evaluating habitat restoration programmes, conservation strategies for Sumatran serows in MLNP will be improved, and the chances of survival for Sumatran serow populations in the future can be maintained.
