<![CDATA[This study is based on environmental pollution caused by excessive use of chemical pesticides and the accumulation of organic waste. Jackfruit peel waste, which can be converted into bioethanol, was utilized together with tobacco leaf waste to produce biopesticides. This study aimed to test the effectiveness of biopesticides made from bioethanol. Bioethanol was produced using Saccharomyces cerevisiae during fermentation. The bioethanol with the highest ethanol content from each variation was used as a raw material for biopesticide production. The measured variables were ethanol content, larval mortality, average time of death, and the percentage of pupa and imago defects, with observations conducted for one week. Mortality data were statistically analyzed. The highest ethanol contents obtained were 30% and 8% for each variation. Larval mortality showed different averages among variations, namely 73.5% and 60%. The fastest average death occurred on the second day, while the highest mortality occurred on the third day, reaching 16.29. The percentages of pupa and imago defects were 5.66% and 14.2%, respectively. The results showed that the biopesticides were effective in causing larval mortality and defects in pupae and imago.
