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: Metode generalized minimal residual(GMRES) dalam menyelesaikan sistem persamaan linear
Abstrak: Metode GMRES (Generalized Minimal Residual) adalah salah satu metode proyeksi subruang Krylov Kapan(r. Ar Aro) untuk menyelesaikan sistem persamaan linear tak-simetrik. Metode ini diperkenalkan oleh Saad dan Schultz tahun 1986. Cara kerja metode GMRES tampak pada algoritma GMRES. Pada algoritma GMRES terdapat 2 tahap dalam menyelesaikan masalah sistem persamaan linear yaitu tahap penentuan basis dan tahap penentuan solusi. Perbedaan yang nyata antara metode GMRES dengan metode yang lain (baik yang menggunakan bantuan subruang Krylov maupun yang tidak menggunakan subruang Krylov) adalah dalam mendapatkan solusi. Pada setiap iterasi algoritma GMRES, selain diperoleh basis subruang Krylov, dapat diperoleh pula estimasi besarnya residu tanpa menghitung solusi aproksimasi pada iterasi tersebut. Dari implementasi metode GMRES yang diterapkan pada matriks JPWH 991, tampak bahwa metode GMRES jauh lebih efisien dalam hal memori yaitu 177.768 bytes, sedangkan metode Gauss memerlukan memori minimal sebesar 982.081 bytes. Juga dalam hal banyaknya operasi floating point (dalam hal ini berhubungan dengan waktu yang digunakan) metode GMRES jauh lebih unggul dibandingkan dengan metode eliminasi Gauss.
