Abstrak: Flies are insects that live close to the human environment. Group of flies that often comes to human settlements are mainly from the family Calliphoridae (Chrysomya megacephala (bluebottle)) and Muscidae (Musca domestica (house fly)). Flies are important insects because they are related to public health. M. domestica can be a vector of various diseases caused by viruses, bacteria, protozoa, and worms. Flies around the settlement were many and carry a variety of diseases that can danger the public health. The aims of this study were to determine species diversity and dominance of flies at various locations around disposal garbages in around Bogor Agricultural University Campus Dramaga. Flies collections were performed on the landfills around the residensces, office buildings, schools, cafes, and markets. Flies were collected using a sweep net by swinging it around the landfills. The collected flies were then identified using identification keys. The result showed that the species of flies that found in various locations around the Bogor Agricultural University Campus Dramaga were M. domestica and C. megacephala. M. domestica was dominant in the areas around of residences, schools, cafes, and markets. C. megacephala was dominant in area around the office buildings.

Abstrak: Flies are filth insect for society notably in food higiene and environment sanitation. Flies were first insect that came to carrion on decomposition process. So far, there only a few researcher about flies diversity on carrion in Indonesia. The purpose of this research was to determine the diversity of flies on carrion indoor. Two rabbits were used in this research. The rabbits were slaughtered at the neck and then were placed indoor area. Flies that came to the carrion were collected with sweep net. Data of environment termperature and humidity were collected for 30 days, included observation of carrion. Flies that were collected from the highest to lowest number were Chrysomya rufifacies, C. megacephala, Calliphora spp., Tachinidae, Chrysomya saffranea, M. domestica, Lucilia sp., and Sarcophaga sp. Fluctuation of environment temperature and humidity did not have correlation with to number of flies arrival. The number of flies were decrease after day of 17th

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
