Abstrak: The aim of the research to study species diversity and density fluctuation of mosquitoes in cattle farm Unit Reproduction and Rehabilitation Bogor Agricultural University (URR IPB). Mosquitoes was collected by light trap from 6 pm to 6 am on June to October 2012. The mosquitoes preservation used pinning method to identify the species. There were 470 mosquitoes from 8 times collections, consisted of 7 species Culex (Cx. tritaeniorhynchus, Cx. gelidus ,Cx. bitaeniorhynchus, Cx. fuscocephalus, Cx. hutchinsoni, Cx. quinqeufasciatus, and Cx. pseudosinensis), 1 species Armigeres (Ar. subalbatus), 1 species Anopheles (An. nigerrimus), and 1 species Aedes (Ae. albopictus). The dominant species was Armigeres subalbatus (35.53%) and Cx. tritaeniorhynchus (21.91%). The highest mosquitoes density was discovered at 6 pm to 7 pm. The result of Pearsons corellation analysis showed that corellation of mosquitoes density to rainfall was -0.641, to humidity 0.21, and to temperature 0.681.

Abstrak: Mosquitoes are insects that cause the most health problems in society, as nuisance insects and vector of various diseases such as malaria, dengue hemorrhagic fever, chikungunya, Japanese Encephalitis, dirofilariasis, filariasis, St. Louis Encephalitis and West Nile Virus. Application of zooprophylaxis as the utilization of cattle to divert mosquito bite from human to animal has not been done in Indonesia. This study was aimed to determine the effect of the placement of cattle around houses to reduce mosquitoes biting to human. Mosquitoes collection on human were done by Bare Leg Collection (BLC) around the houses with and without cattle placement. In the meantime, mosquitoes which come to cattle caught by Magoon trap. The result showed that the density of Cx. sitiens which known as vector of Japanese Encephalitis was 12,05 mosquitoes/man/hour at the houses with cattle and was 16,31 mosquitoes/man/hour at houses without cattle, and very high in cattle was 54,38 mosquitoes/cattle/hour. Density of Anopheles which known as vector of malaria did not show the difference between around houses with and without cattle placement. An. vagus density at house with or without cattle were same (0,01 mosquitoes/man/hour), but very high at cattle (6,12 mosquitoes/cattle/hour). This research showed that placement of cattle as zooprophylaxis application has good potency to reduce mosquito contact to human, which is means it could reduce mosquitoes borne diseases transmission.

Judul: Pelabelan Super Edge Magic pada Graf Cycle dan Graf Wheel
Abstrak: This manuscript proves that cycle graph and wheel graph have a super edge magic labeling. Super edge magic labeling on a graph is labeling that has an edge magic labeling with a set of vertices were mapped in to {1,2,… ,𝑝} and a set of edges were mapped in to {𝑝+1,𝑝+2,… ,𝑝+𝑞}, in which 𝑝 is order and 𝑞 is size on the graph. There are one lemma and two theorems to be discussed. The lemma is used to prove the two theorems. The first theorem proves that cycle graph 𝐶𝑛 is super edge magic if and only if 𝑛 is odd. The second theorem proves that wheel graph 𝑊𝑛 of order 𝑛 is not super edge magic. Moreover 𝑊𝑛 is not edge magic if 𝑛≡0 mod
