Papaya plant is a plant originating from America with the scientific name Carica papaya. Papaya seeds contain flavonoids, glucotropaeolin, and phosphatidyl choline. Flavonoids are chemical compounds that have insecticidal properties. Flavonoids attack the nerves in several vital organs of insects, causing a weakening of the nerves, such as breathing and causing death. This study aims to examine the effect of papaya seed extract (Carica papaya) on the mortality of Aedes aegypti mosquito larvae and to determine the minimum inhibitory concentration of papaya (Carica papaya) seed extract required against Aedes aegypti mosquito larvae. The Aedes aegypti mosquito has a complete metamorphosis, and when it is in the larval stage, the Aedes aegypti mosquito has 4 phases, namely instar I, instar II, instar III, and instar IV larvae. The larvae used in this study were the larvae of the third instar Aedes aegypti mosquito. The research method used is a laboratory experimental method using a completely randomized design (CRD) where there are 4 treatments and 3 repetitions. The concentrations used in this study were 1 positive control, 10 ml, 30 ml, and 50 ml. The results were analyzed by One way ANOVA test followed by Post-Hoc LSD analysis. The results of the research that has been carried out show that the papaya seed extract (Carica papaya) which kills the most Aedes aegypti mosquito larvae is at a concentration of 50 ml, where in the first and second tests succeeded in killing 4 out of 5 larvae. In the last iteration managed to kill 5 out of 5 larvae. And it can also be seen that the minimum inhibitory concentration is at a concentration of 10 ml, where in 3 repetitions it can only kill 2 to 3 larvae from a total of 5 larvae. The 50 ml concentration is also the concentration that has the fastest effect, where on the fifth spray alone, there are already dead mosquitoes. While at a concentration of 10 ml, it takes a longer time, namely the seventh spray.

The Bromo Tengger Semeru National Park (BTSNP) has a high diversity of habitats, making this area a good habitat for mosses. This study aims to explore the types of epiphytic mosses in the BTSNP. The research was conducted from March to April 2013. Mosses were collected using the transect method and plot sampling. Samples were collected at three different altitudes (< 1000 masl, 1000–2000 masl, and > 2000 masl). Three research plots were made at each location with a size of 50x50 m, with a minimum distance of 500 m between plots. In each plot, five trees with a diameter of 10–30 cm were selected. To maximize information related to species diversity, different tree bark textures were selected (rough and smooth). The diversity of epiphytic mosses in the BTSNP was evident in 44 species (11 mosses and 33 liverworts). The highest moss diversity in the BTSNP was found in the Hypnaceae, Lejeuneaceae, and Plagiochilaceae. The diversity of epiphytic mosses in BTSNP was in the moderate category (1<H'<3).

Aedes aegypti and Culex sp. is a vector of dengue, filariasis, and malaria in Indonesia. One of the alternative efforts to control the spread of mosquitoes that are safe and harmless to the environment and humans can be done by giving natural ingredients that have the potential as larvicides, namely bitter melon. The purpose of this study was to determine the effect and effectiveness of bitter melon as a natural larvicide for Aedes aegypti and Culex sp. The design of this study was experimental using samples of bitter melon and fourth instar larvae of Aedes aegypti and Culex sp. The treatments in this study included ethanol extract of bitter melon with concentrations of 250 ppm, 500 ppm, 750 ppm and 1000 ppm, abate 1% as a positive control and aquades as a negative control. All treatments were given to the fourth instar larvae of Aedes aegypti Culex sp. each containing 20 larvae. Data analysis in this study was carried out by One-Way ANNOVA test, Independent sample t-test, and probit analysis. The results showed that the lowest-highest percentage of Aedes aegypti larvae mortality ranged from 26% - 85%, while Culex sp. ranged from 17% - 65%. The results of the ANOVA test showed significant differences between the treatment groups (P<0.05) in both Aedes aegypti and Culex sp. but the results of the Independent sample t-test showed no significant difference (P>0.05) between the Aedes aegypti and Culex sp. The results of the probit analysis showed that the LC50 value for Aedes aegypti was 728,789 ppm while Culex sp was 732,272 ppm. The conclusion of this study was that the administration of ethanol extract of bitter melon was more effective on the fourth instar larvae of Aedes aegypti than Culex sp.
