Aglaonema plants (Aglaonema spp.) are popular ornamental plants that are famous for the beauty and diversity of their leaves. However, pest attacks can disrupt the growth and beauty of this plant. An alternative to controlling pests is to use vegetable pesticides. This research aims to test the effectiveness of organic pesticides derived from bintaro fruit extract and the effect of using banana peels as a leaf polish on Aglaonema plants. Bintaro is a potential source of botanical pesticides because it contains compounds that inhibit insect feeding. On the other hand, banana peels, which are often overlooked, actually have the ability to naturally enrich the leaves because of their nutritional content. This research used a randomized block design (RAK) with six different treatments, including a control without treatment and chemical pesticide treatment as a comparison. The results of the study showed that bintaro fruit extract had no real effect on aglaonema pest attacks, P4 treatment had a real effect, with the highest number of respondents, but P3 treatment tended to give a duller leaf shine. These results show that the use of the botanical pesticide Bintaro fruit extract did not have a significant effect in killing Aglonema pests, but P2 and P3 treatments had a better effect than other treatments in dealing with pests and P4 treatment was the best in shining Aglonema leaves.

Bintaro (Cerbera manghas L.) is widely used as an analgesic, anticonvulsant, cardiotonic, and hypotensive activity. In Thailand bintaro is used as traditional medicine such as bark used as an antipyretic, laxative and in the treatment of dysuria. The flower part is applied to treat hemorrhoids. Secondary metabolites are chemical compounds contained in plants that can be drawn by a suitable solvent through extraction methods. The purpose of this study was to determine the content of secondary metabolites contained in bintaro leaf extract using ethanol, acetone, and n-Hexan solvents based on phytochemical screening. This research was carried out through two stages, namely extraction using maceration method using ethanol, acetone, n-Hexan and phytochemical screening solvents consisting of screening alkaloids, terpenoids, flavonoids, steroids, saponins, and tannins. The results showed that the bintaro leaf ethanol extract positively contained flavonoids, saponins, and tannins. The acetone extract of bintaro leaves positively contains, saponins and tannins. N-hexan daun bintaro extract positively contained steroids and alkaloids in testing with Dragendorft reagents, and was positive for Wagner reagents and negative for testing with Mayer reagents
