Peripllaneta americana are nocturnal animals that transmit typhoid, dysentery, and diarrhea. P. americana is frequently found in filthy environments such as markets, warehouses, and toilets. Apart from that, it is found in bedrooms, bathrooms, kitchens, wardrobes, and even food. Chemical methods have been used to remove cockroaches, but they are hazardous to both human health and the environment. The usage of ecoenzymes derived from nutmeg leaf and pulp waste has great potential as it contains bioactive compounds that can function as bioinsecticides. This research used a completely randomized design with a factorial pattern of 2 × 3 × 3 or 18 treatments, namely, the type of main ingredient (E 1 and E 2), ecoenzyme concentration (K 1, K 2, and K 3), and time after contact (T 1, T 2, and T 3). The measuring parameter in the study was the percentage of cockroach death, which was analyzed using SPSS version 25 for Windows. The results showed that different plant waste’s ecoenzymes also have distinctive colors (E 1 is yellowish brown and E 2 is dark brown), fresh sour smell, pH (E 1 = 3.15 and E 2 = 3.08), temperature (E 1 = 26.4°C and E 2 = 26.03°C), and total dissolved solids (E 1 = 1,263 ppm and E 2 = 1,713 ppm) after fermentation. In addition, there was an effect on cockroaches due to the type of main ingredient, concentration, time after contact, and the interaction of the three on the percentage of mortality of P. americana with LC50 and T50 found in treatments E 2 K 2 T 2 (main ingredient of nutmeg pulp waste, 10% concentration, and time after contact 6 h) and E 2 K 3 T 1 (main ingredient of nutmeg pulp waste, 15% concentration, and time after contact 3 h), so that the resulting ecoenzyme showed positive effects as a potential bioinsecticide of P. americana.
