Compost availability is highly beneficial to agriculture. Using EM<sub>4</sub> Bio Activator, vegetable and fruit waste may be converted into compost instead of being thrown. The objective of this study is to determine the best amount of EM<sub>4</sub> Bio Activator for creating liquid compost. This research uses vegetable and fruit waste, such as pineapple, spinach, banana, long beans, banana stem, papaya, and coconut water, along with a small amount of sugar, as the fermentation's primary ingredient. Variations in the treatment volume of EM<sub>4</sub> Bio Activator were 5 mL, 10 mL, and 15 mL. The fermentation process lasts one week. The results conclude that the addition of 10 mL of EM<sub>4</sub> Bio Activator is optimal for fermenting Vegetable and Fruit Waste (with the amount specified in the study technique) into Liquid Compost or perhaps EM<sub>4</sub> Bio Activator. The approximate ratio for one week of fermentation is 10 mL EM<sub>4</sub> Bio Activator per 1.7 kg of mixed ingredients.</p> ER -
