The golden apple snail, Pomacea canaliculata, has a complex history in Indonesia, where it was originally introduced as an aquarium fauna in 1981 but later became a pest in rice fields. As a result, there is a need for better understanding of the biological aspects of this species to develop efficient control measures. Phytochemical compounds found in plants, such as phenolic components, glucosinolates, and carotenoids, have various biological activities and potential health benefits. However, the phytochemical properties of the golden snail have not been extensively studied. In this research, samples of raw and boiled golden snail meat were analyzed for alkaloids, steroids, flavonoids, saponins, phenol hydroquinone, and carbohydrates using various methods. The results showed that both raw and boiled golden snail meat tested negative for alkaloids, steroids, flavonoids, saponins, and phenol hydroquinone. However, the Molisch test for carbohydrates gave positive results, indicating the presence of carbohydrates in both samples.

These findings contribute to a better understanding of the phytochemical properties of the golden snail and highlight the potential biological activities of these compounds. Further research in this area may lead to the development of more targeted and sustainable control measures for the golden snail as a rice pest. Additionally, the presence of carbohydrates in the snail meat may have implications for its nutritional value and potential uses in the food industry.

The American cockroach (Periplaneta americana) be an insect which are disease vectors for humans. The control of American cockroaches be often carried out by the community by using synthetic insecticides, however the use of synthetic insecticides can have a negative impact on both humans and the environment. Therefore, natural alternatives are needed that are safer for the environment and humans by using vegetable insecticides. Soursop bark contain active compounds that have potential as vegetable insecticides. This study aim to determine ability of soursop bark extract as vegetable insecticide on mortality of adult American cockroaches, to determine LC50 value of soursop bark extract, and to determine compounds present in soursop stem bark. This research conduct from August 2022 to February 2023. Research this research use experimental method with Completely Randomized Design (CRD) with 5 treatments (control (-), 1%, 3%, 5%, and control (+)) and 5 repetition. Average American cockroach mortality calculate after 24th, 48th, and 72nd hours. Data that obtain analyze using One Way ANOVA. Results show that soursop bark extract be effective as nabatic insecticide against American cockroach mortality with LC50 value of 2.89%. Bioactive compounds that contain in soursop bark extract be alkaloids, flavonoids, saponins, steroids, and tannins.
