Evaluation of Sugar Content
and
Quality
of
Sweet
Sorghum
Bioethanol,
Sorghum bicolor (L) Moench
in Kawali and Super-1
Varieties with Solid Organic
Fertilizer

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 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 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. The interaction between the two factors had no significant effect (P>0.05) on all variables. It was discovered that the leading variety of sweet sorghum (Super 1) produced more glucose (12.43o brix) and bioethanol (1.03o 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.

Fossil energy as the fuel source in the world is decreasing. This research aims to provide bioenergy as an alternative renewable 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. As a preparation, efforts must be made to select leading sorghum varieties and cultivars capable of producing the most ethanol. There are several types of sorghum that are cultivated, including 1) Local grain sorghum, used for food and animal feed, as well as for raw materials for beverages and bioethanol manufacturers, 2) Broomcorn, its stalks are used for making brooms, and 3) Sweet sorghum, its stem liquid is used as raw material for making syrups (Sugiono, 2011) and raw material for ethanol making (Daniel et al., 2017). •••••••••••••••••••••••••••••••• ejprd.org- Published by Riset Publishing Services LLC.
