Judul: Keragaman Lalat Diptera pada Bangkai Kelinci di dalam Ruangan
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

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.

Judul: Peran Surfaktan Setiltrimetilamonium Bromida dan Natrium Dodesil Sulfat pada Sintesis ZnO dengan Metode Hidrotermal
Abstrak: Zno crystal is the main preference material in various applications recently, such as in semiconductors, ultraviolet lasers, and catalysts. This study aims to synthesize ZnO with addition of surfactant. ZnO crystals were synthesized by reacting ZnSO4, KOH, and surfactants using hydrothermal method. The first step was to determine the best ratio of ZnSO4: KOH (1:2; 1:3; 1:4, and 1:5) based on X-ray diffraction. The second step was to evaluate the role of surfactan cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) on the synthesis of ZnO crystals. The result of this study showed the best ratio of ZnSO4:KOH was 1:3, based on the least of impurities and the highest degree of crystallinity (85.64%). The addition of surfactant CTAB and SDS in the synthesis of ZnO increased the degree of crystallinity, which were 98.28% and 92.17%, respectively. Based on mathematical calculation using Scherrer equation, the crystal size without surfactant was 32 nm, whereas with CTAB and SDS the crystallited size were 28 nm and 29 nm, respectively. The degree of crystallinity and crystal size indicated that CTAB surfactant produce ZnO crystals with the best characteristics as compared to SDS surfactant or without surfactant.
