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: Fruit flies are the most important pests for many fruits and vegetables which cause quantitative and qualitative losses of production. Bogor and its surrounding area have many fruit fly host plants. The aim of this research was to investigate the diversity and distribution of fruit flies species and their hosts at Bogor and its surrounding area as well as constructing the identification key for found species. Fruit flies were collected at 119 sampling areas in Bogor and some places of Cianjur, Bekasi and Depok. Collection of samples were using 2 methods: host rearing and trapping. Modification of Lynfield trap and 2 attractants such as metil eugenol (ME) and Cue lure (CL) were used in the trapping. There were 18 species of fruit flies collected from traps and 23 host plants. Distribution, diversity and abundance of fruit flies was influenced by the diversity of host plants.

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.
