The use of larvae Hermetia illucens L. by the community has recently increased specifically as animal feed and organic liquid fertilizer but still has various obstacles. The constraints faced in maintaining their low performance in life include the low quality and quantity of harvested larvae that will be used as commercial material. It is, therefore, formulated by formulating nutritional use b…
Tenebrio molitor larvae have a high protein content so they can be used as feed for aves, fish, reptiles to humans. Utilization of these larvae makes breeders look for the right feed for the growth and survival rate of T. molitor larvae. Intake of nutrients such as carbohydrates, protein and water greatly affects the growth rate and survival rate of T. molitor larvae. The mixed feed of wheat br…
Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus through a vector in the form of the Aedes aegypti mosquito. Synthetic larvicides are a mainstay for thecommunity in controlling the Ae. aegypti mosquito vector. The use of synthetic larvicides can cause resistance to larvae, so it is necessary to look for other alternatives to overcome these problems, namely by using vegetab…
Sungkai (Peronema canescens Jack.) belongs to the Verbenaceae of plants native to Indonesia. The content contained in sungkai leaves can be used as an alternative to natural medicines because they are safer and have low side effects. Sungkai is a wild plant, but because this plant has economic value. Propagation of Sungkai plant (Peronema canescens Jack.) through seeds is difficult because it o…
Aedes aegypti L. is the main factor of dengue fever. The control of the A. aegypti mosquito vector that is often carried out by the community is synthetic larvicides, but synthetic larvicides can cause various environmental problems, for that we need a safer alternative for humans and the environment in the form of biolarvicides. This study aims to determine the effect of extract and fraction o…
