The research was to knowing effectivenes of sand Sea-cucumber (Holothuria scabra) flour to maskulinization fish of cupang (Betta splendens) are held in Desember 2011 until February 2012. The research method used experiment method with design of experiment are complete random device (RAL). The research consits of three treatment are treatmen of B (dose of sea-cucumber 10 mg/l), treatment of C (dose of sea-cucumber 20 mg/l), treatment of D (dose of sea-cucumber 30 mg/l), while control consist of treatment of A (dose of sea-cucumber 0 mg/l) and treatment of E (17α-metiltestosteron dose 10 mg/l) with 3 times restating. Treatment of sand sea-cucumber flour are given for larva fish of cupang wich old age 4 day with soaking during 6 hour. Observed parameter are the male sex ratio, pass of life and environmental factor are the temperature, pH, Oxygen content dissolved and carbondioxyde content dissolved, while data are analyzed with ANAVA resulth and further rested by LSD at 5% level of confidence. The results of experiment showed that teh highest percentage of male fish at treatment of D (dose 30 mg/l) are 66,66% and the lowets of treatment of A (dose 0 mg/l) are 39,77%. From these results it can be concluded that the sand sea-cucumber flour hae given to test larva effectiv to maskulinization fish of cupang female become male.Keyword: Betta splendens, Sand sea-cucunber flour, 17α-metiltestosteron and maskulinization

A research was conducted to find out the effect of papaya latex (Carica papaya L) toward the mortality of Aedes albopictus larva, in Laboratory of Biology Faculty of Education Teacher Training and Education University of Riau in November 2011 to April 2012. The method used in this research was experimental method to the preparation of a random sample consisting of 5 treatments which are repeated for 3 times. The number of larva are 10. Parameter observed is Aedes albopictus larva mortality as long as 96 hours, LC50 value and toxic response of Aedes albopictus larva which could be showed by body movement, posture and body color of larva. The data of this research was analyzed by probit and deskriptif analysis. The supporting parameters is temperature and pH of the medium. The results of the research showed that the papaya latex (Carica papaya L) could make the mortality of Aedes albopictus larva. Mortality of Aedes albopictus larva in concentration 27 ppm was 100% in 24 hours, in concentration 18 ppm was 100% in 72 hours, mortality of Aedes albopictus larva in concentration 12 ppm and 8 ppm was 80% and 50% in 96 hours. LC50 value in 24 hours was 26.30 ppm, in 48 hours was 20.41 ppm, in 72 hours was 14.12 ppm and 96 hours was 9.12 ppm. The roxic response of Aedes albopictus larva showed the mobility of the less agile, larva body roll, the larva's body parallel to the surface of the water and the color of pale white body. From the result of the research can be concluded that the papaya latex can potentially lead to death of Aedes albopictus larva and the concentration recommended for application to the environment is 9.12 ppm in 96 hours.Keywords: Aedes albopictus larva, Papaya late.
