Swietenia macrophylla or big-leaf mahogany is an exotic species from Central and South America. This tree has various benefits, so it’s used as an industrial plantation forest and afforestation in Indonesia. However, seed storage of mahogany is a major problem in cultivation, because it can reduce seed viability. The storability of seeds is influenced by seed and environmental conditions. Therefore, this study aimed to examine the effect of temperature and storage time on the viability of S. macrophylla seeds and to calculate the Seedling Quality Index (SQI). The experiment was carried out using a factorial Randomized Block Design (RBD) with 2 factors. The first factor was consisted of four levels of temperature treatment, namely room temperature (24), 4, 0, and -20°C. The second factor was the storage period treatment which consisted of 4 levels, namely 1 up to 4 weeks, with 1-week intervals. The results showed that the interaction between temperature and storage time affected mahogany leaves, primary and secondary roots, root/shoot ratio, and total wet weight of S. macrophylla seedlings. Mahogany seeds that were stored at room temperature for 1 week resulted in the highest seed viability, with SQI of 0.03-0.04.

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.

Cultivated oil palm is commonly found in several ecosystems with different topographies, including riparian areas. This ecosystem is expected to affect the morphology and physiology of oil palms. In addition, oil palm habitats in riparian or flooded ecosystems will experience anaerobic respiration. Indonesia has the potential to access quality palm oil that can be used for cultivation. This study aimed to determine which oil palm accessions could adapt physiologically to the duration of waterlogging. The accession of oil palm seedlings from Jambi tested were Merangin, Tebo, Muara Jambi, Tanjung Jabung, and Simalungun. The research design was to treat waterlogging in a greenhouse and then analyze the plant growth and physiology. Waterlogging was given for two, four, and six weeks. The results showed that the accession of oil palm seedlings and the duration of waterlogging affected photosynthesis rate, transpiration rate, and stomatal conductance. Growth parameters, i.e., fresh weight, dry weight, and root/shoot ratio, were significantly different in accession and waterlogging duration. In conclusion, accessions from Tebo and Merangin can adapt to waterlogging. Keywords: Merangin accession, photosynthesis rate, stomatal conductance, Tebo accession

Fine roots (≤2 mm diameter) are a plant organ that plays a major role in nutrient and water acquisition from the soil and a parameter for understanding belowground changes. Fine root traits can determine the plant's strategies in maximizing resource acquisition for productivity with an acquisitive strategy or maximizing resource investment with a conservative strategy. In this study, enrichment planting was carried out in oil palm plantations through a combination of oil palm and tree crops. It is necessary to determine whether enrichment planting can impact the nutrient and water acquisition of oil palm fine roots. Therefore, this study aimed to determine the nutrient and water acquisition strategies of oil palm fine roots enriched with crop species by analyzing differences in morphological traits through fine root inventory. The enrichment planting treatments were R0 (plot of oil palm without enrichment crop), R1 (plot of oil palm with one crop), R2 (plot of oil palm with two crops), R3 (plot of oil palm with three crops), and R6 (plot of oil palm with six crops/multispecies). The results showed that enrichment planting in oil palm plantations can be practiced with two and three crop species, as in plots R2 and R3, which support a conservative strategy with high RTD (root tissue density) and low SRL (specific root length) and SRA (specific root area) in oil palm fine roots. In contrast, high species diversity in plot R6 triggered a shift to an acquisitive strategy with high SRL and SRA and low RTD.

Arrowroot (Maranta arundinaceae L.) is a starch–producing plant that can potentially be used as an alternative substitute for wheat flour. Additionally, arrowroot can serve as a functional food, as it is not only a source of nutrition but also provides health benefits such as improving digestion and regulating blood sugar levels. Arrowroot tubers contain high levels of carbohydrates and bioactive phenolic compounds that function as antioxidants. Currently, no data is available on the nutritional content and antioxidant activity (DPPH assay) of arrowroot tubers from various regions of Java Island. This study aimed to analyze the quality and antioxidant activity of arrowroot tubers obtained from several locations in Java. The results of the proximate analysis (moisture and ash contents) showed that the lowest moisture content was in the Banjar 1 accession (3.44%), while the highest was in the Sragen 3 accession (12.47%). The Banjar 2 accession had the highest ash content (8.94%), while the Sragen1 accession had the lowest (3.98%). The antioxidant activity was indicated by the IC50 value, which is the concentration of the sample solution required to inhibit 50% of DPPH free radicals. Antioxidant activity analysis revealed that the Malang 1 accession had the lowest IC50 value of 163.16 ppm, indicating the highest antioxidant potential.

Salinity stress disrupts redox homeostasis in plants, leading to notable changes in the levels of bioactive compounds. These compounds are recognized for their significant role in inhibiting the α-glucosidase enzyme, which is relevant in glycemic control. Detailed insights into how salinity stress modulates α-glucosidase inhibition in mulberry leaves remain scarce. This study aims to investigate the effects of salinity stress on α-glucosidase inhibitory activity in mulberry leaf extracts, and to identify accessions exhibiting the most potent inhibitory properties. In vitro assays were employed to conduct qualitative phytochemical analyses and to quantify total phenolic content, total flavonoid content, and α-glucosidase enzyme activity. The results demonstrate that high salinity stress enhances the inhibitory activity of mulberry leaf extracts against the α-glucosidase enzyme. Notably, the MB2-3 sample exhibited the most favorable IC50 value (0.59 µg/mL), coupled with a substantial phenolic content (141.9 mg GAE/g extract) and the highest content of flavonoid observed among all tested samples (619.56 mg QE/g extract). Collectively, these findings highlight the capacity of salinity stress to augment both the inhibitory potential of mulberry extracts against α-glucosidase and the accumulation of phenolic and flavonoid compounds, with sample MB2-3 displaying auspicious attributes.

Rhizome with high productivity and content of bioactive ingredients is the hope to be achieved from the cultivation of galanga (Kaempferia galanga L.). Galanga is used traditionally as a medicine for stomach ulcers, colds, headaches, coughs, diarrhea, facilitating menstruation, skin diseases, and rheumatism. Production of secondary metabolites is influenced by environmental factors and the place of growth. This study aims to determine the effect of the growing environment from two different locations on the essential oil content and its constituent components from the rhizome of the galanga accessions. The samples observed were nine accessions of galanga harvested at 6 months which were planted in the Bogor, namely Darmaga (L1) and Cisarua (L2) with a altitudes of 214 m asl and 780 m asl with different agro-climatic conditions. The accessions tested included Purbalingga (PBG), Cilacap (CLP), Purworejo (PWJ), Karanganyar (KRA), Pacitan (PCT), Madiun (MAD), Galesia 1 (GAL 1), Galesia 2 (GAL 2), and Galesia 3 (GAL 3). GAL 1, GAL 2, and GAL 3 are high yielding varieties of galanga that have been released by the Minister of Agriculture of the Republic of Indonesia and used as comparisons based on their essential oil content. Observations were made on the levels of essential oils and their constituent compounds using GC-MS (Gas Chomatography-Mass Spectroscopy). Differences in growing places affect the content of essential oils and their constituent components from the rhizome of the galanga accession. Environmental factors that influence are sunlight and water availability. The highest essential oil content (3.78%) was obtained from the MAD accession planted in Cisarua (L2) and the highest EPMS compound (34.74%) was obtained from the PCT accession planted in Darmaga (L1). There were 73 compounds detected with four main components, namely delta-3-carene, pentadecane, ethyl cinnamate, and ethyl p-methoxy cinnamate (EPMS).

ABSTRACTMelon (Cucumis melo L.) is a high economic value horticultural crop that is cultivated in some regions of Indonesia under fertilization management. Application of inorganic fertilizer continuously can reduce soil microbial abundance. One of the soil microbial that promote plant growth is arbuscular mycorrhizal fungi (AMF) and Azospirillum sp. The aim of this study was to analysed the effect of AMF and Azospirillum sp. in promoting growth and production of melon. The experiment was carried out in a greenhouse and was arranged in a completely randomized design with five replicates. Five treatments tested were: control, fertilized with NPK, inoculated with AMF, inoculated with Azospirillum sp., inoculated with AMF + Azospirillum sp. The results showed that the effect of AMF on root growth and shoot growth were similar to NPK fertilizer. Azospirillum sp. increased root growth. On the other side, the effect of Azospirillum sp. on shoot growth was similar to NPK fertilizer. However, AMF and Azospirillum sp. inoculation solely increased plant height, fruit weight, fruit diameter, flavor and length of fruit storage. Meanwhile, combination of AMF and Azospirillum sp. increased plant height, root growth, shoot growth, fruit weight, fruit diameter, flavor and length of fruit storage. This study revealed that application of AMF and Azospirillum sp. in melon cultivation was more effective and efficient than NPK fertilizer.Keywords: arbuscular mycorrhizal fungi, Azospirillum sp., Cucumis melo L.

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.
