Abstract
This study aims to determine the potential of mangrove apple extract (Sonneratia alba) as a botanical insecticide. Tests were conducted to observe the bioactivity of mangrove apple extract and phytochemical tests were conducted in order to see the content of bioactive compounds. The test results showed that the mortality rate of test larva (Nezara viridula) reached 98%, while the phytochemical test showed that the mangrove fruit contains phytotoxin compounds that can affect the behavior and even kill the test larvae. The compounds found are flavonoids, triterpenoids, alkaloids, tannins, steroids, phenolics, and saponins. The influence of flavonoid compounds is strong enough to attract insects.

The fine powder of mangrove apple (S. alba) was 20 grams macerated with methanol, hexane, and ethyl acetate solvents with a solvent height of ± 1 cm above the sample
Summary
The issue of environmental pollution makes the developed countries become more alerted to the export of agricultural commodities. This can be seen by the increasingly stringent regulations relating to ecolabelling. The requirements contained therein are very difficult to be applied by businesses, government, and society as to impede the export of Indonesian agricultural products (Suwanto, 1994; Suwahyono, 1996). The government has been instrumental in overcoming the problem of pollution of agricultural waste by applying environmentally friendly technology. Ecotechnology is one way to solve environmental problems, ie technologies that require little energy and produce waste as little as possible or without waste at all (Said, 1994; Utami & Rahyu, 1996)
