Kampar River is one of the flooded swamp areas in Riau Province. Hemibagrus hoevenii is one of the most abundant fauna in the Kampar River. One of the important keys in fish identification is the morphometric character. The study was conducted to determine the morphometric differences of male and female H. hoeveniifish in Langgam and Tambak Village, Kampar River using a survey method with …
Indonesia is known for its diversity of banana cultivars. Banana populations generally decline due to pathogen attacks, including the pathogenic fungus Fusarium oxysporum f.Sp. cubense, which causes fusarium wilt. Banana germplasm resistance to this disease can be detected through SCAR (Sequence Characterized Amplified Region) molecular markers. This study aims to ana…
Maman plant (Cleome gynandra L.) is commonly consumed as a fermented vegetable by the Rokan Malay community in Riau province. Apart from the potential nutritional and ethnopharmacological benefits of maman plant, maman plant from Riau have not been studied much so information about this species is still difficult to obtain. The purpose of this study was to analyze the rbcL DNA barcode sequence …
Meniran contains phytochemicals. One of these is a flavonoid that acts as an immunomodulator and has potential as an antiviral. The supply of meniran comes mostly from natural harvesting, raising concerns about scarcity of meniran. Increasing the availability of meniran can be through cultivation and increasing secondary metabolites through drought stress. Drought stress on meniran can increase…
