Main Material

Blood fever and Chikungunya cases in Indonesia are increasing annually. For preventing the mosquios, people use mosquito coil which is contain dangerous chemical compound. This research has successly created a natural mosquito coil with gemor bark and hazelnut fruit shell as the main material. Gemor bark is positive containing alcaloid,tanin, phenolk, flvonoid, triterpnoid and glycocydic compounds which are natural bioinsecticide. As formulation the comparison of gemor bark and hazelnut shell as follow :100% : 0 %  ; 80 % : 20 % ; 65 % : 35 % ; 50 % : 50 % ; 35 % : 65% and 20 % : 80% were used. Base one random variance analysis, the best formula was the using of gemor bark in 50%, 35% and  20% of concentration. The mosquitos killing force analysis was using the LT50 for 6 days with 5 diferent concentrations. The result showed that 50 %  of gemor bark was significantly influenced in the killing force. From the economic view, the producion of this coil was cheaper then the same product in the maket. Base on all the result, the research product is applicable in mass producion and safe for human health and the environment.Keywords: gemor bark , hazelnut fruit shell ,  mosquito coil, natural ,  ecofriendly

Abstract Although relatively recent, peach culture has grown great in our country due to the special quality of the fruit, its very complex chemical composition and the large production that can be obtained without much effort. Peach is a species slightly adapted to our climatic conditions, suffers from winter frost, but can provide productive and long productions of 10-15 years.

Lipstick is one kind of cosmetics which is used as lips colorant to increase self-confidence. Nowadays, lipsticks from natural source is popular to reduce the negative impact of chemical compound or synthetics colorant in lipstick intensively for health. Super red dragon fruit is one kind of natural ingredients which can be used as colorant for lipstick. Moreover, this fruit is rich of antioxidant and antibacterial component that is good for skin health. In this research, extract of super red dragon fruit flesh was added in the lipstick during preparation with variation of concentration 0, 10, 20, 30 and 40%. Antioxidant analysis resulted the IC50 value in 81.55% indicating the strong antioxidant properties. Furthermore, the concentration of dragon fruit extract 40% was able to inhibit the growth of Staphylococcus aureus bacteria.
