Abstract

Dengue Hemorrhagic fever (DHF) is caused by a dengue virus that spreads through the bite of the Aedes aegypti mosquito, which breeds a lot in densely populated areas with humid and warm climates. Anti-mosquito drugs in the form of burns, sprays, lotions, or other types are already widely used, but these anti-mosquito drugs are not entirely beneficial. This research is purely experimental research with Post-test Only Control Group Design by making air spray solution products from noni leaf infusion and cananga flower, which are analyzed descriptively and analytically. Experiments carried out with Randomized Complete Design 1 time repetition to analyze effectiveness. The study used two factors: treatment (P) using infusion products while the control (K) using distilled water. From the results of mixing, it was obtained as much as 400 ml of infusion solution. Obtained in each measurement, there was a reduction in live larvae until the last measurement. Noni leaf contains five flavonol glycosides (flavonoid compounds) as respiratory poisons and a combination of saponins and tannins as stomach poisons that have the killing power against the death of Aedes aegypti larvae. Cananga flower extract itself can resist mosquitoes because of the content of linalool, geraniol and eugenol. This makes a change in the larvae's behavior, where the previously active movement will be slow and eventually will die.

Abstract

The use of electrical energy from year to year is increasing, but the source of electrical energy has limitations. This electrical energy crisis must be addressed immediately, one of which is using environmentally friendly and renewable fuels. One of the environmentally friendly sources of electricity is the fruit of the mahkota dewa (Phaleria macrocarpa). The purpose of writing this paper is to investigate the benefits of the crown of the gods as an alternative source of electrical energy. The subject of this research is the crown of the god fruit with the criteria that the fruit is ripe which is marked with a red color which will be used as an alternative source of electrical energy to replace batteries. In addition to its medicinal properties, the results of this study indicate that the crown of the god fruit contains alkaloid compounds (bases) that can generate electricity. The electric voltage generated from the four pieces of the crown of the god can reach a voltage of 1.8 V. Meanwhile, the current generated from one crown of the god is very small and only produces a voltage of 0.9 V. The use of the crown of the gods as a source of electrical energy has a number of advantages in addition to some of the disadvantages it has. Based on the results of research on the power source from the crown of the god, it can be concluded that the hypothesis that there are benefits of the crown of the god as an alternative source of electrical energy is acceptable.
