“…mitis can lower rice grain production by 12.7 to 42.6% by inhibiting photosynthesis rate, root weight, root oxidation activity, and biomass accumulation (Zhang et al, 2017). Alridiwirsah et al (2022) added that barnyardgrass had five populations in lowland rice, with root length and volume of 39.4cm and 246.1ml and dry weight of roots and shoots of 92.7 g and 65.6g, respectively.…”

“…According to Tahir (2016), the barnyardgrass from several locations in Arkansas has a leaf length of 16.2 to 30.0cm, a leaf width of 1.2-1.5 cm, upper glume of 2.94 to 3.80mm, lower glume of 1.21 to 1.68mm, an upper lemma of 2.71 to 3.55mm, and 7,186-71,494 seeds per plants. Alridiwirsah et al (2022) also added that the upper epidermis, mesophyll, lower epidermis, and stomata density of barnyardgrass leaves from lowland rice plants were 44.3 μm, 155.6μm, 40.8μm, and 69.0n/μm, respectively.…”

I N LOWLAND rice areas, the presence of barnyardgrass weed (Echinochloa crusgalli) is disadvantageous to Indonesian farmers and requires an initial assessment and identification of characteristics for management. Therefore, this study aimed to obtain the characteristics and similarities of barnyardgrass accessions from lowland rice fields based on the morphological characteristics of the seed. A descriptive-analytical method was used to determine the barnyardgrass characteristics of 45 accessions from nine subdistricts in Serdang Bedagai and one accession from Medan City (MDN), Indonesia, as a comparison. This study was conducted from May to August 2022 and the data were analyzed using one-way ANOVA, followed by Tukey's test at P<0.05. The hierarchical cluster and constellation plot were generated using Ward's method. The results showed that 45 accessions of barnyardgrass from lowland rice fields had sizes of upper glume, lower glume, upper lemma, flag leaf length, and flag leaf width ranging from 2.93 to 4.33mm, 1.45 to 1.96mm, 0.03 to 17.10mm, 22.77 to 45.40cm, and 0.53 to 1.13cm, respectively. Among all accessions, only PG4 accession was nearest (1.825) to MDN. Furthermore, there were five clusters with 13 accessions including SB4; PC1; PC5; PG3; PG4; BK1; BK3; BK5; PB1; PB2; TB2; TB1; and TT2, classified in the same cluster as MDN. This information is very important as an initial reference for farmers in the management of barnyardgrass weeds in their lowland rice fields.

“…M. micrantha is rich in terpenoids, phenolics, flavonoids, alkaloids, tannins, saponins, glycosides, and steroids [51,52]. The literature consistently show that natural ACE inhibitors can be found in plant secondary metabolites containing terpenoids, phenolic, flavonoids, hydrolysable tannins, xanthones, procyanidins, and caffeolyquinic acid derivatives [44].…”

Mikania micrantha Kunth (Asteraceae) is a plant traditionally used to reduce the risk of hyperlipidemia and hypertension. There is limited information on the anti-hyperlipidemic and anti-hypertensive effects of the various M. micrantha leaves and stem extracts. This study aimed to examine the in vitro potential of different parts of M. micrantha (leaves and stem) extracts in inhibiting hyperlipidemia-related enzymes, i.e., pancreatic lipase (PL), lipoprotein lipase (LPL) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR), in addition to the hypertension-related, i.e., angiotensin-I converting enzyme (ACE). This study spectrophotometrically determined the inhibitory activities of hot water, cold water, 70% ethanol, and ethyl acetate M. micrantha leaves and stem extracts against the above-said enzymes using PL, LPL, HMGR, and ACE inhibition assays. The study found that the ethanol stem (ETS) extract exhibited the highest PL inhibitory activity (IC50=4.49±2.50 μg/mL), albeit the difference was insignificant (p > 0.05) compared to orlistat (IC50=0.31±0.01 μg/mL). Meanwhile, the ethanol leaves (ETL) extract yielded the highest LPL (IC50=1.42±0.48 μg/mL) and HMGR inhibitory activity (50.12±3.44%), although the greatest ACE inhibition was observed for the hot water stem (HWS) extract (97.47±1.19%). However, the result was insignificant (p > 0.05) compared to other extracts and captopril (98.42±0.93%). In brief, the extracts generally exhibited remarkable inhibitory activity against PL, LPL, HMGR, and ACE, thus conveying the M. micrantha extracts' anti-hyperlipidemic and anti-hypertensive potentials.

“…Plants, including weeds, produce allelochemicals that defend against pests, diseases, and competition from other plants (Kong et al, 2019). In addition, Alridiwirsah et al (2022) found that Mikania micranta extract had alkaloids, flavonoids, saponin, and tannins as well as an extract concentration of 20-100%, which effectively suppressed the biomass of barnyard grass weeds by 46.0-63.5% in lowland rice area. Weeds that exist in swampland are not widely known for their compund content.…”

Weeds are plant disturbing organism that affect yields through competition and allelopathy. However, not much is known about weed diversity in swamps, so research is needed to identify their types and compounds as a weed control strategy. This study was conducted using a survey method from January to March 2020 at the Barito Kuala District, South Kalimantan. Thirty villages were randomly selected from each of the eight chosen subdistricts. Out of the twenty-six weed species identified, there were ten species of grasses, seven sedges, and nine broadleaves. The results showed that the weed species were dominated by Cyperus halpan, Eleocharis dulcis, and Cynodon dactylon (L.), with an SDR of 23.46, 16.73, and 10.03, respectively. The analysis of GC-MS showed that the weeds contained four similar compounds: neophyte diene, palmitic acid, linoleic acid, and stigmasterol. The largest compound content in C. halpan was diisocotyl phthalate (48.49%), while in E. dulcis and C. dactylon the largest were o-phthalic acid and mono-2-ethylhexyl-ester (69.36 and 40.23%). Moreover, weed allelochemicals are classified into fatty acids, steroids, esters, and other volatile compounds, where some have the potential for allelopathy that inhibits crop growth.
