Abstract

Rice Blast has been known as the main disease on paddy which has high severity leading to economic loss. Exploring rice resistance can be an effective way to improve productivity and prosperity toward this staple crop. This study aims to determine several local varieties which have potential for productions and resistances. This study used factorial randomized block design (RBD) consisting of 2 factors including plant spacing (25 x 25 cm; 25 x 30 cm; 25 x 40 cm); Upland rice variety MSP 17, Sigambiri Merah, Hamparan Perak and Kambiri Lumat. The results of the study reveal that variety has a significant effect on disease intensity especially Sigambiri Merah but not on Kembiri Lumat. However, there is no significant effect of spacing on blast intensity except in grain weight. Conclusion of this research was the varieties (V) selection of red upland rice is the best strategy to improve rice resistance toward blast disease. Keywords:  Disease density, Paddy, Staple Crop.

Abstract

This study, entitled Identification of Secondary Metabolite Compounds in the Stems and Leaves of Surat Dibata (Macodes petola) Using Gas Chromatography Mass Spectrometry (GCMS) aims to determine the compounds and their concentrations of secondary metabolites present in the stems and leaves of Surat Dibata (Macodes petola) using Gas Chromatography Mass Spectrometry (GCMS). The methods used in this study include maceration extraction to identify secondary metabolite compounds and Gas Chromatography Mass Spectrometry (GCMS) to determine the concentrations of these compounds in the stems and leaves of Surat Dibata (Macodes petola). The results of the study showed that the extraction identified secondary metabolite compounds such as steroids in the stems and flavonoids, steroids, and tannins in the leaves. Based on the results from the GCMS analysis, the stems were found to contain 0.63% steroids, while the leaves contained 0.002% flavonoids, 0.002% tannins, and 2.215% steroids.
