    Herbal plants have several potential antimicrobial activities either as antifungal or antibacterial to fight against the disease and pathogen that attack the plants. The extractions of the Aloe vera leaf, Citrus hystrix leaf, Zingiber officinale rhizome and Sabah snake grass were selected in this study to fight against Bacillus subtilis. B. subtilis is a Gram-positive bacterium, rodshaped and catalase-positive that lives on decayed organic material. It is known as Gram-positive bacteria because of its thick peptidoglycan and would appear purple when subjected to Gram test. This species is commonly found in the upper layers of the soil, in meat or vegetables, in pastry, cooked meat, in bread or poultry products. The extracts of Sabah Snake Grass found to be most effective than A.vera leaf, Z. officinale, and C. hystrix against the B. subtilis.

    This paper study the effect of ethylene scavenger treatments in different quantity (T0: 0g, T1: 1g, T2: 3g, T3: 5g and T4: 10g per sachet) and types of packaging (T5: non-perforated and T6: perforated packaging) on Musa Acuminata to its shelf life and physicochemical quality. Potassium permanganate (KMnO4) and zeolite were used as ethylene absorbent which stored together with the bananas under uniform atmospheric condition at temperature of 25-28°C and 85-95% of relative humidity (RH). Physicochemical analysis (e.g. weight loss, peel colour changes, firmness, total soluble solid content and titratable acidity) were performed to evaluate the effectiveness of each treatments throughout its storage period. Results showed that treatment with higher quantity of KMnO4-zeolite (T4: 10g) shows reduction and retardation in percent weight loss (9.62%), peel colour changes, firmness changes (28.2%), total soluble solid (TSS) (12.1% Brix), titratable acidity (TA) (0.084% malic acid) and also greater storability of banana. Therefore, postharvest losses can be reduced by the mentioned treatment and it can be implemented in postharvest industries for extending the shelf life of banana effectively.
