The objectives of this research are to determine the best (i) the best genotype for germination and growth of dogfruit seedlings (ii) combination of shade and genotype, (iii) the best percentage of shade and. This research was carried out by direct observation of seed germination and seedling formation. The study was carried out in an experimental garden located ± 255 meters above sea level. The average temperature and mean humidity during the experiment were 27 ºC and 65%, respectively. The experiment used a completely random design consisting of two factors. The first factor was shade (0%, 40%, or 80% shading). The second factor was genotype (bareh and lokan). Data were analysed using analysis of variance and significant differences were further analysed using Duncan’s New Multiple Range Test at the 5% level. Observations for determining the time of radicle appearance, root length, radicular colour, and germination type seeds were germinated in seedbeds. Temperature and humidity were recorded in every observation. The best interaction with respect to leaf area is 80% shade cloth and the lokan genotype. Eighty percent shade cloth is the best for germination and growth of Dogfruit seedlings. The best genotype for germination and growth is lokan. It is recommended to use 80% shade cloth because it provides optimal growth of Dogfruit seedlings.

Pulsed electric field-assisted extraction of Djenkol (Archidendron pauciflorum) peel: Characterization, suppression of intracellular ROS generation and inflammatory cytokines in LPS-activated RAW264.7 macrophage cells

Djenkol (Archidendron pauciflorum) peel is a source of phenolics with an antioxidative activity. Nevertheless, the high extraction efficacy of the target compounds is crucial for the isolation of such compounds. Pulsed electric field (PEF)-assisted extraction is the means that increase the efficacy of extraction via an electroporation mechanism. This research aimed to study the extraction of phenolics with antioxidative activities using the PEF and to investigate the anti-inflammation and antioxidative activities of the Djenkol peel extract (DPE) in RAW264.7 macrophage cells. The PEF at different electric field strengths (E) (4.5 and 6 kV/cm) and times (180, 360, and 540 ms) was implemented to extract the phenolic compounds. The PEF with the E level at 6 kV/cm for 540 ms provided the highest yield, the total phenolic content, and antioxidative activities, compared to other conditions (P < 0.05). The dominant compounds in the DPE were the gallic acid and catechin. When the RAW264.7 cells were treated with the DPE at different levels (0.125, 0.25, 0.5, 0.75 and 1 μg/mL), the DPE at 0.125 and 0.25 μg/mL had no cytotoxicity, compared to the control (P < 0.05). With adding lipopolysaccharide (LPS), the DPE-treated cells at 0.125 μg/mL showed the similar cell viability to that of the control (P < 0.05). Additionally, the use of the DPE, particularly at 0.125 and 0.25 μg/mL, could reduce the TNF-α and IL-6 levels and reactive oxygen species (ROS) generation in the LPS-activated cells. Thus, the DPE could be used as a functional ingredient in food.

BSLT and DPPH Methods to Determine the Potential Toxicity of Archidendron Pauciflorum Skin to Artemia Salina and the Antioxidant Potential as an Early Exploration of Anti-Cancer Drugs

Archidendron pauciflorum skin is a dense waste that pollutes the environment and can be a problem if not properly cleaned. According to previous research, Archidendron pauciflorum skin has a very high potential because it contains flavonoid components and polyphenols with anti-cancer and antibacterial properties. To evaluate the toxicity activity with the BSLT Method and the antioxidant DPPH Method, the scalp is cut into small pieces, dried in the oven at 60 °C, and then macerated for 24 hours in a mixture of methanol and ethyl acetate solvents as well as hexane to produce polar, semipolar, and non-polar chemicals. The fibre from each solvent is collected, and the rotary evaporator is used to evaporate it until a thick extract is produced. According to the final findings of the study, the LC50 value (μg/mL) for each solvent is: the methanol value is 111 ppm, while ethyl acetate is 192 ppm. While for the test of antioxidant activity, significant results were obtained on the methanol solvent with an IC50 value of 51.13 μg/mL The conclusion of this study is that the 24-hour maceration period is the most efficient solvent for toxicity to Artemia salina and antioxidants to continue further research in the search for anti-cancer drugs.

Keanekaragaman Arthropoda Permukaan Tanah Pada Pertanaman Bawang Merah (Allium ascalonicum L.) Pada Lahan Gambut yang Diaplikasikan Kulit Jengkol

Shallots are a spice commodity that is very important in everyday life. Shallots are one of the commodities that greatly influence the level of economic inflation. This commodity experienced a decline in production of 101%. In 2017 it could produce 28,456 quintals while in 2018 it produced 14,155 quintals. This can be caused by several things that exist in the environment around the plantation. This research aims to determine the diversity of arthropods in Allium ascalonicum shallot plantings. This research was carried out from October - to December 2021 on Tegal Arum Village Land, Banjarbaru City. The research method uses an exploration method carried out directly at the location of the shallot trap plantation and treated with jengkol (Archidendron pauciflorum) skin powder using a Pitfall ground surface trap.

Native arbuscular mycorrhiza colonization in seedling root of dogfruit (Archidendron pauciflorum) planted as seed-ball in field

Arbuscular mycorrhiza (AM) is a mutualistic symbiosis between soil fungi and plants, including dogfruit (Archidendron pauciflorum). Archidendron pauciflorum is a local plant from Southeast Asia, including Indonesia that is used for food and animal forest feed. Planting A. pauciflorum seedlings on revegetation land with a sharp slope is difficult and dangerous to workers. Therefore, seed-ball planting technique is required for revegetation of post-mining sharp slope areas. This research aimed to study the ability of the native AM fungi to colonize A. pauciflorum seedlings grown as a seed-ball in the field for revegetation purposes. The seed-ball was made using three types of fungal inoculum sources, namely control without AM fungi, natural forest, and stockpile inoculum. All colonization structures, such as entry points, coils, arbuscules, and vesicles, were observed. All seedlings were colonized by AM fungi, with root colonization ranging from 2% to 16%. Stockpile inoculum had a higher AM colonization than the natural forest inoculum. Both sources of native AM fungi tended to improve the growth of the seedling. There were two types of AM spores found in all treatments, Glomus sp. 1 and Glomus sp. 2. Glomus sp. 2 is the dominant species of AM fungi in all treatments.

The role of Leguminosae plants for soil fertility in oil palm plantations

The greatest and most lucrative plantation product in Indonesia is palm oil. The availability of nutrients in the soil affects how oil palm plants grow and develop. To overcome the low availability of nutrients in the soil to meet the needs of plants, fertilization operations are required. The concept of a green economy necessitates that the palm oil industry limits its usage of chemical fertilizers as well as chemical pest and disease management. Oil palm plants require a variety of fertilizers that are rich in macronutrients (N, P, and K), secondary nutrients (Ca and Mg), and micronutrients (B, Zn, and Cu). The potential use of biodiversity as a soil fertility agent, such as Leguminosae plants, must be researched. The purpose of this study is to define the function of Leguminosae plants in oil palm farms’ soil fertility. Several scientific papers that were pertinent to the research issue were studied for literature as part of the data collection process. Oil palm plantations in Indonesia have implemented the planting of legume cover crops (LCC). Planting LCC suppresses weed growth, protects the soil from direct sunlight and raindrops, reduces surface runoff, maintains soil moisture, and increases soil fertility. Neustanthus phaseoloides var. javanicus, Calopogonium caeruleum, C. mucunoides, Mucuna bracteata, M. pruriens var. utilis, and Centrosema pubescens are a few Leguminosae plants that can be used as cover crops. In addition to these species, planting Parkia timoriana, P. speciosa, and Archidendron pauciflorum trees can help improve soil fertility. Oil palm plantations with legumes have a higher clay texture, an average pH of 6.0, and high levels of N-total, P, K, and C-organic, whereas non-legume oil palm plantations have a sandy texture and high dust, an average pH of 5.3, and very low levels of N-total, P, K, and C-organic. Legumes, in addition to being a cover crop, can also be used as animal feed and to increase nutrient levels in plants. Planting LCC in oil palm plantations can affect the nutrient content of forages that grow under oil palm trees because the root nodules of LCC contain rhizobium bacteria that function to fix nitrogen from the air and are converted by the nitrogenase enzyme into ammonium and nitrate as a source of N for the LCC. The concept of integrated plantations can be applied to oil palm plantations by using LCC, which has hampered the growth of oil palm plants as animal feed, and P. timoriana, P. speciosa, and A. pauciflorum trees as economically valuable food plants.

Selenium Organic Content Prediction in Jengkol (Archidendron pauciflorum) and Its Molecular Interaction with Cardioprotection Receptors PPAR-γ, NF-κB, and PI3K.

Selenium (Se) is a trace mineral found in plants with a distinct sulfuric odor that is cardioprotective and reported to have low toxicity. West Java, Indonesia, has a variety of plants with a distinct odor that are consumed raw, such as jengkol (Archidendron pauciflorum). This study is conducted to determine the Se content of jengkol using the fluorometric method, where the jengkol extract is separated, and the Se content is detected using high-pressure liquid chromatography (HPLC), combined with fluorometry. Two fractions with the highest Se concentration (A and B) are found and characterized using liquid chromatography mass spectrometry to predict the organic Se content by comparing the results with those in the external literature. The Se content of fraction (A) is found to be selenomethionine (m/z 198), gamma glutamyl-methyl-selenocysteine-(GluMetSeCys; m/z 313), and the Se-sulfur (S) conjugate of cysteine-selenoglutathione (m/z 475). Furthermore, these compounds are docked on receptors involved in cardioprotection. The receptors are peroxisome proliferator-activated receptor-γ (PPAR-γ), nuclear factor kappa-B (NF-κB), and phosphoinositide 3-kinase (PI3K/AKT). The interaction of receptor and ligan that has the lowest binding energy of the docking simulation is measured with molecular dynamic simulation. MD is performed to observe bond stability and conformation based on root mean square deviation, root mean square fluctuation, radius gyration, and MM-PBSA parameters. The results of the MD simulation show that the stability of the complex organic Se compounds tested with the receptors is lower than that of the native ligand, while the binding energy is lower than that of the native ligand based on the MM-PSBA parameter. This indicates that the predicted organic Se in jengkol, i.e., gamma-GluMetSeCys to PPAR-γ, gamma-GluMetSeCys AKT/PI3K, and Se-S conjugate of cysteine-selenoglutathione to NF-κB, has the best interaction results and provides a cardioprotection effect, compared to the molecular interaction of the test ligands with the receptors.

The Antibacterial and Antibiofilm Activities of the Endophytic Bacteria Associated with Archidendron pauciflorum against Multidrug-Resistant Strains.

Endophytes associated with medicinal plants are a potential source of valuable natural products. This study aimed to evaluate the antibacterial and antibiofilm activities of endophytic bacteria from Archidendron pauciflorum against multidrug-resistant (MDR) strains. A total of 24 endophytic bacteria were isolated from the leaf, root, and stem of A. pauciflorum. Seven isolates showed antibacterial activity with different spectra against four MDR strains. Extracts derived from four selected isolates (1mg/mL) also displayed antibacterial activity. Among four selected isolates, DJ4 and DJ9 isolates exhibited the strongest antibacterial activity against P. aeruginosa strain M18, as indicated by the lowest minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) (DJ4 and DJ9 MIC: 7.81µg/mL; DJ4 and DJ9 MBC: 31.25µg/mL). 2 × MIC of DJ4 and DJ9 extracts was found to be the most effective concentration to inhibit more than 52% of biofilm formation and eradicate more than 42% of established biofilm against all MDR strains. 16S rRNA-based identification revealed four selected isolates belong to the genus Bacillus. DJ9 isolate possessed nonribosomal peptide synthetase (NRPS) gene, and DJ4 isolate possessed NRPS and polyketide synthase type I (PKS I) gene. Both these genes are commonly responsible for secondary metabolites synthesis. Several antimicrobial compounds, including 1,4-dihydroxy-2-methyl-anthraquinone and paenilamicin A1, were detected in the bacterial extracts. This study highlights endophytic bacteria isolated from A. pauciflorum provide a great source of novel antibacterial compounds.
