“…The inhibition is thought to occur because phenols, tannins, flavonoids, steroids, and terpenoids affect the P. littoralis seed cell membrane. This means that the process of seed germination metabolism is inhibited because the water imbibition process and transport of food reserves are disrupted (Kusuma et al 2016). According to Santoso and Purwoko (2008), disruption in the imbibition process can inhibit seed germination metabolism.…”

Abstract. Oksari AA, Susanty D, Wanda IF. 2019. Allelopathic effect of invasive species air potato (Dioscorea bulbifera) on seeds germination of Polyalthia littoralis. Nusantara Bioscience 11: 63-70. Dioscorea bulbifera L. (Dioscoreaceae) is included in the Global Weed Compendium and one of the invasive plants that cause environmental problems in many parts of the world. This study aims to determine the effect of allelopathy from various concentrations of leaf and tuber extract from D. bulbifera on seed germination of Polyalthia littoralis (Blume) Boerl. The method used was a Completely Randomized Design (CRD) with seven treatments and three replications. The treatment given was the concentration of D. bulbifera extract 10%, 20%, 40%, 60%, 80%, 100% and aquadest solvent control. The results of phytochemical screening analysis showed that the extract of leaves and tuber of D. bulbifera did not contain alkaloids, but specifically on leaves extract contained tannins. Both extracts contained steroids, flavonoids, and saponins. Based on the results of the study, total phenolic obtained in the leaf extract as much as 28.81 ± 2.51 mg TAE/g extract, while the tuber extract had a total phenolic of 6.74 ± 1.19 mg TAE/g. The results showed that allelopathic substances of D. bulbifera affected the germination of P. littoralis seeds. Based on DMRT test at 5% level, it was known that allelopathy concentration of D. bulbifera significantly affected the germination rate at concentrations of 20%, 60%, 80%, and 100% and significantly affected the coefficient of velocity of germination at a concentration of 20%. But, concentration allelopathy of D. bulbifera had no significant effect on the coefficient of uniformity of germination. The concentration that reduced the lowest seed viability was at a concentration of 80% with an average germination power of 56.67 ± 7.45%.

“…-sitosterol (7,08%). DDMP merupakan senyawa golongan flavonoid yang bekhasiat sebagai antimikroba, antiinflamasi, dan antikanker (Ramalakshmi & Muthuchelian 2011), dan juga mampu menghambat pertumbuhan gulma daun lebar yang merugikan (Kusuma et al 2017). Selain itu, polifenol termasuk senyawa flavonoid diketahui dapat meningkatkan produksi ASI (Mohanty et al 2014;Iwansyah et al 2017).…”

Torbangun (Plectranthus amboinicus) merupakan tanaman obat dari keluarga Lamiaceae. Pada masyarakat Batak, daun torbangun digunakan untuk meningkatkan produksi air susu. Keragaman kandungan fitokimia dapat ditingkatkan salah satunya dengan teknik iradiasi sinar gamma untuk program pemuliaan tanaman. Pada penelitian ini, metode metabolomik yang tidak tertarget digunakan untuk mengevaluasi profil senyawa pada bagian daun tanaman mutan dari iradiasi sinar gamma dan kontrol. Kandungan senyawa planlet mutan dan kontrol dianalisis dengan GC-MS. Data GC-MS dianalisis dengan kemometrik dengan menggunakan hierarchical cluster analysis (HCA). Keragaman kandungan kimia ditunjukkan oleh planlet mutan dan kontrol daun torbangun. Hasil analisa planlet kontrol torbangun menunjukkan terdapat lima senyawa utama diantaranya hydroxymethylfurfurole (35,15%), brevifolin (7,69%), 3-Dihydro-3,5-Dihydroxy-6-Methyl-4H-Pyran-4-one (DDMP) (13,13%), stigmasterol (6,51%) dan ferruginol (8.63%). Hasil analisa mutan torbangun memiliki kandungan senyawa DDMP (19,57%), neophytadiene (8,47%), linolenic acid (9,10%), ferruginol (7,61%), stigmasterol (14,14%) dan gamma.-sitosterol (7,08%). HCA menunjukkan tiga komponen senyawa yang berbeda antara planlet kontrol dan mutan yaitu kenaikan kandungan senyawa DDMP dan stigmasterol, serta penurunan kandungan hydroxymethylfurfurole pada mutan torbangun.

“…Tumbuhan yang dikatakan masyarakat sebagai gulma ini sebenarnya dapat digunakan untuk mangatasi pencemaran air, tidak hanya itu dinegara india gulma ini dimanfaatkan untuk menjernihkan air akibat limbah tekstil yang dibuang ke sungai (Kadam et al, 2018). Cyperus sphacelatus Rottb merupakan jenis teki-tekian dengan habitat di daerah kering dan daerah basah seperti rawa, merupakan jenis gulma dengan petumbuhan yang sangat cepat sehingga dengan jumlah yang sangat banyak, mengganggu tumbuhan lain, dengan menyerap unsur mikro dan makro dalam tanah serta melepaskan zat alelopati sehingga menghambat perkecambahan tumbuhan lain (Kusuma, Chozin, & Guntoro, 2017).…”

The number of aquatic plants along the river flow outside the village of Lambur becomes a barrier to water traffic so that these plants are classified to be weeds or a nuisance for local people. This study aims to determine and document the types of weeds found in the village of Lambur and explore locals’ knowledge about the types of existing water weeds and their use. This research was conducted in the Village of Lambur Luar Tanjung Jabung Timur District by using the roaming method to collect existing Weed samples. Data collection is done by observation, interviews, documentation and literature studies, the data are analysed descriptive qualitative design. The results showed that there were 19 species and 13 families of water weeds, namely: Fimbristylis sp1, fimbristylis sp2, Cyperus sphacelatus Rottb, Blyxa aubertii Rich, Lindernia sp, Glinus oppositifolius (L.) Aug.DC, Melastoma malabathticum L, Nymphaea nouchali Burn, Ludwigia hyssopifolia (G.Don) Exell, Ludwigia repens JR Forst, Scoparia dulcis, Hippochaete debilis (Roxb.ex Vaucher) Ching, Panicum repens L, Oryza sativa, Persicaria hydropiper L, Monochoria vaginalis (Burm.f.) C.Presl, Borreria alata (Aubl.) DC, Borreria repens DC, and Xyris sp. Of the 19 species found, only 12 species, the locals know the name of the water weed, 7 species are only referred to as grass only by the locals, this water weed is not used by the them but mostly weeds are used for animal feed, the researchers provide education to the community that actually weed water can be used for treatment and to find out the quality of a waters or be used as an indicator of the biological condition of a river in wheteher good condition or not.
