“…The benzoic acid compound that was indicated by GCMS analysis as the largest compound in biopesticides was due to the addition of preservatives in the form of sodium benzoate. Sodium benzoate is well-known for its effectiveness against yeasts, moulds, and bacteria, potentially being a bacteriostatic and anti-fungal preservative under acidic conditions (Amalia et al, 2020;Castle et al, 2004;Pongsavee, 2015). Benzoic acid, which is usually used in the form of its sodium salt, sodium benzoate, has long been used as an antimicrobial additive in foods (Takayuki & Bjeldanes, 1993) and reportable to perform as fragrance ingredients, pesticides, the potential of Hydrogen adjusters, preservatives, solvents, and viscosity decreasing agents in cosmetic products (Gottschalck, 2006;Johnson et al, 2017).…”

The high consumption of cigarettes, especially in Indonesia, will produce harmful waste for the environment called cigarette stubs. The waste of cigarette stubs reacts with any kinds of pathogenic fungus such as Fusarium oxysporum, Colletotrichum gloeosporiodes, Rigidoporus lignosus, and Sclerotium rolfsii. The usage of cigarette stubs as an alternative raw material for making organic pesticides can make cigarette stubs considerable as a recycled product that reduces the environment's waste. The results obtained by plants treated with biopesticides effectively resist pest attacks and support plants to naturally develop antibodies. The score of Intensity Attack (IS) from Terminalia cattapa plant applied by the biopesticides for 10 days observation results in the amount of 3.953%, with a total of 34 normal leaves and a total of 12 broken leaves. The other result of the Terminalia cattapa applied with chemical pesticides gives 12.31% of intensity attack and 12.18% of intensity attack without any treatment. This research concluded that tobacco could inhibit the attack pest of the Terminalia cattapa plant.
