Malaria is still one of the most highly pathogenic diseases, which remains a significant problem for public health. Natural compounds are alternative ways as an antimalarial compound that are applied for the artemisinin combination. The aim of this study was to determine the effect of a combination of S. ligustrina extract and DHP on the differential leukocytes percentages. This study used 100 mice which were divided into five groups. Group A and B were used for the healthy mice and infected-untreated groups, respectively. Group C used as a controlled drug, received 222 mg/kg BW of DHP. Group D received 300 mg/kg BW of aqueous extract of S. ligustrina. Group E received a combination between 111 mg/kg BW of DHP and 200 mg/kg BW of aqueous extract S. ligustrina. The findings demonstrated that DHP and S. ligustrina extract had an impact on neutrophils, lymphocytes, inhibition, and percentages of parasitemia. The findings revealed that treatment groups C, D, and E reduced the percentage of parasitemia. The percentage of neutrophils in treated groups was significantly higher than in group A (P<0.05). The percentage of lymphocytes was lower in the treated groups, while the percentages of eosinophils, monocytes, and basophils did not significantly different (P<0.05). This study found that group D and E had the same effect on the leucocyte profile as group C. Our findings suggest that the aqueous extract of S. ligustrina, as well as the combination treatment with DHP, have the potential to lead to the discovery of new antimalarial medicines.

The aim of the study was to analyze the content of pelawan wood extractive substances (Tristaniopsis whiteana (Griff)) and to test it with the fungi Schizophyllum commune Fr and Pleurotus ostreatus. Pelawan heartwood powder was macerated with methanol. Then fractionated in stages with n-hexane, chloroform, ethyl acetate, and butanol. The resulting extract was then tested with S. commune and P. ostreatus fungi. The most active fraction was isolated using column chromatography with a gradient system, the eluent was methanol:chloroform. Sub-fractions were then tested for fungi to determine the most active sub-fractions, and the most active sub-fractions were then analyzed by 1H NMR. The results showed that the extractive content of pelawan wood was most soluble in chloroform. All extract fractions contain potential as anti-fungal. .The chloroform fraction was very active compared to the other fractions. Isolation of the chloroform fraction by column chromatography obtained 8 sub-fractions. All of these sub-fractions were able to inhibit the growth of S.commune and P.ostreatus with IC(50) = 54.55 - 64.69 mg/L and IC(50) = 54.17 - 64.44 mg/L respectively. PL.3 sub-fraction was the most active among the 8 sub-fractions. The results of 1H NMR analysis on the PL.3 subfraction were shown to be Heptanoic Acid compounds.

The dissolution of wood lignin in the alkali solution were analyzed for two fast growing species, sengon (Paraserianthes falcataria) dan leda (Eucalyptus deglupta). Wood samples were extracted in 1% sodium hydroxide solution in cold and hot temperatures for 24 and 1 h, respectively. Extractable substances content, permanganate consumption (expressed as assumed lignin content) were analyzed from the filtrates, lignin content and diastereomeric of β-O-4 structure were analyzed from the wood residue after alkali extraction. The extracted substances from both of wood in hot alkali was higher than in cold alkali solution, although the time of cold alkali extraction was much longer that hot alkali extraction. Assumed lignin content in the extract was quite high in both samples which were 34.4-42.9% and 35.5-39.8% including 2,15-2,29% dan 1,04-1,32% of lignin for cold and hot alkali extraction, respectively. The changes in stereo isomeric form, erythro and threo, of β-O-4 structure of lignin in wood residue indicated that partial depolimerization of lignin was takec place during alkali treatment.

Agarwood leaves (Aquilaria malaccensis), a non-timber forest products, shows significant potential as a source of antidiabetic compounds. This study aims to evaluate the antidiabetic activity of agarwood leaves and their cytotoxicity on pancreatic beta-cells, as well as predict their compound bioactivity through an in silico approach. The leaves were extracted using ethanol, water, and a mixture of ethanol–water with the assistance of ultrasound irradiation. The extracts were then tested in vitro for their antidiabetic potential by assessing their ability to inhibit the alpha-glucosidase enzyme and their effect on insulin secretion, as well as their cytotoxicity on BRIN-BD11 pancreatic beta-cells. The phytocompounds in the extract were identified using liquid chromatography-mass spectrometry, and their binding behavior was studied by in silico molecular docking. Among the three, the ethanol–water extract showed the highest extraction yield. Cytotoxicity assays revealed that the ethanol–water extract was cytotoxic at high concentrations (1000 µg/mL), but safe at lower concentrations. The alpha-glucosidase inhibition was relatively weak. Nevertheless, the extracts significantly stimulated insulin secretion in BRIN-BD11 cells up to fivefold compared to untreated cells. In silico studies indicated that xanthone glycoside, flavonoid glycoside, and coumarin compounds exhibit strong binding affinities to multiple insulin-secretion-related proteins. These findings suggest that agarwood leaf extract, particularly ethanol–water extract, possesses promising antidiabetic activity through an insulinotropic mechanism.

Electrical storage and distribution devices become important in next generation to help integrate more renewable energy intothe electricity grid. Supercapacitor technology is considered the most promising alternative to Li-ion batteries, which have limitedLithium material. However, the low energy density is a weakness of supercapacitors, even though they have a high-power density.Activated carbon-based supercapacitor electrodes have ideal potential for development. The inherent attributes of activated carbon,pore properties, and functional groups, are responsible for improving the performance of supercapacitors. The main challenge for theresearchers is the pore size distribution, micro (<2nm), meso (2–50 nm), and macro (>50 nm), which varied in activated carbon.Micro pores have an impact on increasing the value of specific capacitance values which will encourage an increase in energy density.Meso pores have an impact on the overall accessibility of the electrode surface by electrolyte ions. Future studies will emphasize oncarbonization and activated carbon activation techniques to improve the surface quality of activated carbon.

The development of gamal wood (Gliricidia sepium Jacq.) aims to meet the needs of biomass energy in rural areas. Manystudies on extractives of gamal wood have been carried out, but there is very little information about the effect of extractives on thecalorific value. The effect of extractives on the calorific value can be determined by analyzing extractives compounds contained in thewood. This study aimed to determine the extractives compounds that affect the wood calorific value. The sawdust of gamal bark andwood was extracted by successively maceration by using solvents with different polarities. The free-extractives sawdust was thenmeasured for its calorific value. To ascertain the effect of extractives on the calorific value, the extract of the gamal bark and woodwas added to the oil palm sawdust, then the increase in calorific value was measured. The results showed that the extractives ingamal bark and wood affect the change of calorific value. The removal of extractives by using different solvents caused a differentdecrease in calorific value. The highest decrease in calorific value (4.03%) was obtained by non-polar (n-hexane) soluble extractiveof the gamal bark. The addition of gamal wood extracts to oil palm sawdust also causes an increase in the calorific value.Phytochemical and LC-MS/MS analysis of n-hexane soluble extractives from gamal bark detected groups of terpene compounds,amides alkaloids, flavonoids, coumarins, and benzopyrans. Based on the results of this study, the n-hexane soluble compounds wassuspected to have the most influence on the calorific value.

Activated carbon has been used widely for various applications. Hydro-char which is hydrothermally carbonized from biomass could be used as an alternative precursor for activated carbon manufacture, which is commonly obtained from pyrolized-char. This paper observes crystalline structure of Acacia mangium’s pyrolized-char and hydro-char using XRD (X-raydiffraction). The mangium wood was carbonized in 200°C and 300°C and depth analysis was conducted based on activated carbon product. Result shows carbon maturity index and aromaticity from both precursors (conventional and alternative) tends to increase after being activated; interlayer spacing (d002) is getting closer; meanwhile, crystallinity is greater; and the number, height as well as width of aromatic layers are increasing. Hydro-char exhibited crystallinity degree, maturity and aromaticity lower than those of the pyrolized-char obtained at 300°C carbonization, with the greater volatile content. Both types of char perform carbon structure with amorphous texture. The greatest iodine adsorption is achieved by hydro-char which was carbonized at 300°C. In general, XRD analysis on low temperature carbonization of pyrolized-char and hydro-char could predict the porosity of activated carbon.

Combined microwave pretreatment is an effective method to modify carbohydrate and lignin structures of fungal and lignocellulosic materials, thereby improving the hydrolysis process for bioethanol conversion. This study aimed to evaluate the structural changes in carbohydrate and lignin components of betung bamboo following a combined biological–microwave pretreatment. Based on previous findings, a 30-day incubation using 5% and 10% (w/v) inoculum loading of the white-rot fungus Trametes versicolor—which showed the highest delignification selectivity—was selected as the fungal pretreatment. Microwave irradiation was then applied for 5, 10, and 12.5 minutes at 330 W. Characterization of structural changes was conducted using FTIR spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). FTIR analysis revealed that the combined pretreatment affected only the intensity of absorption bands without altering the functional groups. A decline in peak intensity occurred at 1,736 cm⁻¹ (C=O in xylan), 1,373 cm⁻¹ (C–H deformation in cellulose and hemicellulose), 1,165 cm⁻¹ (C–O–C vibration in cellulose and hemicellulose), and 895 cm⁻¹ (β-glycosidic linkage in cellulose). The pretreatment reduced hydrogen bonding in cellulose and weakened lignin–carbohydrate linkages associated with bamboo cellulose crystallinity. A slight increase in crystallinity index was observed due to cleavage of the amorphous fraction. SEM imaging confirmed the disruption of fiber structure, showing increasing degradation with longer microwave exposure durations.
