Abstract

The purpose of conducting this research is to determine the effectiveness of blue ternate (Clitoria Ternatea) leaf extracts for terminating mosquito wrigglers by making a mosquito larvae insecticide. To determine the effectiveness of the leaf extract to terminate mosquito wrigglers, a mortality test was conducted. The numbers of the dead mosquito wrigglers were checked every 5 min. The results showed that the blue ternate leaf is effective to eliminate mosquito wriggler and the amount of leaf extract in the ethanol brings different effectiveness. The present study showed that both ethanolic extract and pure leaf extract of Clitoria Ternatea are effective as insecticidal against mosquito wrigglers. The insecticidal effects of Clitoria Ternatea against mosquito wrigglers will contribute largely to the people, to help those people who cannot afford to buy insecticide and to lessen the number of people who encounter diseases caused by mosquitoes.

Abstract

The purpose of this research was to determine the potential and capability of water hyacinth (Eichornia crassipes) as bioplastics. The produced bioplastic was naturally biodegradable and can be used for natural conservation without environmental destruction.  The study was experimental using various compositions of water hyacinth, characterized by tensile strength and biodegradability tests to determine the potentiality and capability of water hyacinth as a source of bioplastic. In making the bioplastic, we extracted the water hyacinth and utilized glycerine as a plasticizer, water as the solvent, corn-starch as a thickener, and vinegar. After mixing all materials on a pan, the mixed solution was placed on a stainless surface and dried. After a 3-day curing period, the results showed that different mechanical and decomposition properties were obtained. Based on the results of the study, water hyacinth is one of the suitable materials that can be used to produce a new and sustainable bioplastic material. It is organic and accessible, thus making it a candidate for innovation in the creation of bioplastic. Therefore, we believe that the use of water hyacinth is a potential bioplastic material that is beneficial to the environment and the community.
