Judul: Infestation of Tropical Fowl Mites and Feather mites in Layer poultry farm in Kuningan, West Java
Abstrak: Poultry is a domesticated animal that are using for meat, eggs and their feathers for human purposes. The problem that often found in the poultry is the presence of ectoparasites such as ticks, fleas, mites and louse on their body. The aim for this study is identify and estimate the prevalence of ectoparasites on layers in several poultry farms in Kuningan, West Java. Total of 80 layer hens were randomly selected from different four layer farms as sample for mite’s collection without consideration for age. The mites were collected from 5 different regions of hen at head and neck, wings, thorax and abdomen, tail and legs. The result shows that 70 out of 80 layer hen had been infested by mites. Total of 1842 mites had been found in 70 infested layer hens. Farm 4 had the highest prevalence of mites which is 100% and the least prevalence with 60% is found in farm 3. Prevalence of mite’s infestation that occurs on layer hen in Kuningan is around 87.5%. Type of mites that had been found consists of two species which are Ornithonyssus bursa (3.80%) and Megninia ginglymura (96.20%). Thorax and abdomen are recorded as highest infestation of mites with 30.35%. Type of mites that dominates in this study is Megninia ginglymura in thorax and abdomen region (29.42%) and least dominate region is wings (10.26%).

Judul: Diversity of flies species in layer poultry farm
Abstrak: Lalat merupakan parasit yang dapat ditemukan dengan mudah di peternakan ayam petelur. Penelitian ini bertujuan untuk menelaah keragaman jenis, kelimpahan nisbi, dan dominasi spesies lalat pada peternakan ayam petelur. Pengambilan sampel dilakukan di peternakan ayam petelur KM 45, Kemang, Bogor, menggunakan tangguk serangga. Seluruh sampel selanjutnya diidentifikasi dan dianalisis untuk mengetahui kepadatan lalat. Kepadatan lalat dinyatakan dengan kelimpahan nisbi dan dominasi spesies. Hasil penelitian menunjukkan terdapat 4 jenis lalat yang ditemukan di peternakan ayam petelur, yaitu Musca domestica, Chrysomya megacephala, Chrysomya saffranea, dan Hermetia illucens. M. domesticamerupakan lalat yang paling dominan. Dominasi spesies lalat pada peternakan ayam petelur secara berurutan adalah lalat M. domestica (42.13%), C. megacephala (33.71%), H. illucens (18.26%), dan C. saffranea (5.90%). Ketiga jenis lalat yang terakhir selalu ditemukan bersamaan dengan lalat M. domestica., Flies are common parasites that easily can be found in layer poultry farm. The aim of this research was to analyze the diversity of species, the relative abundance, and the dominance of flies in layer poultry farm. The samples were collected from Peternakan Ayam Petelur KM 45, Kemang, Bogor, by using the sweeping net. The collected samples were identified and analyzed to determine the density of flies. Fly density expressed with relative abundance and species domination. The result showed there were 4 species of flies found in layer poultry farm. They were Musca domestica, Chrysomya megacephala, Chrysomya saffranea, and Hermetia illucens.M. domestica were the most dominant species. Species domination in sequences were M. domestica(42.13%), C. megacephala (33.71%), H. illucens (18.26%), and C. saffranea (5.90%). The last three species were commonly found along with M. domestica.

Judul: Penyelesaian Numerik Persamaan Schrödinger untuk Molekul BaO dan SrO Menggunakan Model Potensial Morse
Abstrak: Morse potential is a potential model used to describe the behavior of a molecular vibration between atoms. This study aimed to obtain the value of the dissociation energy, the energy eigenvalues of each energy level, and describe the shape of the wave function of the molecule BaO and SrO on the vibrational state. Dissociation energy is calculated by adding the experimental dissociation energy and the ground state energy eigenvalues. Calculating the energy eigenvalues of the energy levels 0 to 4 using shooting method integrated with Numerov and Runge-Kutta method. Energy eigenvalues of each levels that calculated numerically having accuracy of 100% compared with the calculated analytically. The profil of wave functions accurately show the corresponding states and their normalized wavefunctions.
