Abstract: Fossil energy as a fuel source in the world is decreasing. This research aims to provide bioenergy as a renewable alternative energy source, namely sweet sorghum (Sorghum bicolor (L.) Moench), which is cheaper, safer, and reduces air pollution. The specific objective is to increase the production of glucose content and stem bioethanol in several varieties of sorghum against panicle pruning and the dose of organic fertilizer given.
This research examines sorghum varieties to observe the contents of glucose and bioethanol in the stems of sorghum varieties (Sorghum bicolor (L) Moench) in response to fertilization. The design used for the research was: RAK Split Plot, two treatment factors arranged factorially with four repetitions. The first factor was variety, namely: Kawali and Super 1. The second factor is the dose of organic fertilizer (5, 10, 15 tons/h-1). The research started from September 2021 to January 2022 in the Padanggalak area, Sanur Village, Denpasar City.
The results showed that the various treatment had a very significant effect (P<0.01) on the variables of plant height at 77 days after planting: stem glucose content, stem juice (sap) production, bioethanol yield, leaf chlorophyll content, and leaf sucrose content. While the effect of fertilizer dose had a very significant effect (P < 0.01) on the variables of plant height, diameter, and stem glucose content in plants aged 77 days after planting. The interaction between the two factors had no significant effect (P>0.05) on all variables but had a very significant effect (P<0.05) on the variable of plant height 77 days after planting. It was discovered that the leading variety of sweet sorghum (Super 1) produced more glucose (12.43% brix) and bioethanol (1.03% brix) than the Kawali variety. The organic fertilizer dose of 10 tons h-1 gave a plant height of 169.46 cm higher than the other two fertilizer doses.
Keywords: sweet sorghum, glucose contents, stem juice (sap) production, bioethanol.
