Judul: Infestasi Telur Cacing Parasitik pada Tinja Kerbau Lumpur (Bubalus bubalis)
Abstrak: The productivity of buffalo in Indonesia was decreased continously. Buffalo productivity can be affected by worm infection. The productivity declined were body weight climbdown, growth delayed even mortality increased. This research was aimed to evaluated infestation of parasitic egg worm in swamp buffalo (Bubalus bubalis) faeces. This research used four of female buffaloes (K1-K4). Faeces sample taken for four week at five points were top, bottom, center, right and left of buffalo faeces. The methode which applied was simple flotation, McMaster, and gradient filtration. Two genus trematoda eggs was identified, Fasciola and Paramphistomum with low degree of infection. The mean size of eggs were 155.6 μm × 97.03 μm for genus Fasciola and 145.34 μm × 83.08 μm for Paramphistomum. The third buffalo (K3) had the highest infection by genus Fasciola, while the others by Paramphistomum. Egg production in four weeks seemed to be fluctuative. In five point which observed for egg production there were not significantly different

Judul: Infestation of Fly (Diptera: Cyclorrapha) Ectoparasite on Buffalo (Bubalus Bubalis) in Ragunan Wildlife Park, South Jakarta
Abstrak: Kerbau (Bubalus bubalis) merupakan ternak ruminansia besar yang penting bagi masyarakat Indonesia. Ektoparasit lalat menjadi salah satu penyebab masalah kesehatan pada kerbau selain mengganggu kenyamanan hidup ternak. Penelitian ini bertujuan untuk mengetahui jumlah infestasi ektoparasit lalat dan faktor-faktor aktivitas inang (host) berupa waktu aktivitas, berteduh, dan berkubang yang berhubungan dengan jumlah infestasi ektoparasit lalat pada kerbau. Pengamatan dilakukan terhadap tiga ekor kerbau jantan pada tiga waktu aktivitas, yaitu pagi (06.00-07.00 WIB), siang (11.00-12.00 WIB), dan sore hari (16.00-17.00 WIB), dan di saat yang bersamaan diamati juga apakah kerbau sedang berteduh atau berkubang. Pengamatan ektoparasit lalat pada kerbau dilakukan setiap hari, selama 14 hari, secara eye-catching dengan menggunakan alat bantu teropong. Penghitungan ektoparasit lalat pada masing- masing waktu dilakukan sebanyak tiga kali (ulangan). Hasil penelitian menunjukkan bahwa infestasi lalat pada kerbau didominasi oleh lalat Muscidae sebanyak 92,4% dan sisanya lalat Calliphoridae sebanyak 7,6%. Tingkat infestasi ektoparasit lalat lebih tinggi pada aktivitas di siang hari (47,5%) dibandingkan pada pada (32,2%) dan sore hari (20,3%). Sementara itu, aktivitas berteduh dan berkubang dapat mengurangi jumlah infestasi ektoparasit lalat pada kerbau., Buffalo (Bubalus bubalis) is a large ruminant livestock that is important to the people of Indonesia. Fly ectoparasites are one of the causes of health problems in buffalo besides that can interfere with the comfort of livestock life. This study aimed to determine the number of fly ectoparasite infestation in buffalo and the association of host activities with the infestation. Three male buffaloes in Ragunan Wildlife Park, South Jakarta were observed in three activity times, namely in the morning (06.00-07.00 WIB), in the afternoon (11.00-12.00 WIB), and in the evening (16.00-17.00 WIB); and at the same time, it was also observed whether the buffalo was taking shelter or wallowing. The infestation of fly ectoparasites in buffalo was observed everyday during 14 days in an eye-catching manner using binoculars. The number of fly ectoparasites was counted three times of each time (as repeatation). The results showed that flies in buffalo was dominated by Muscidae flies (92,4%) and the other was Calliphoridae flies (7,6%). The rate of fly ectoparasite infestation was higher during the afternoon activity (47,5%) compared to the morning (32.2%) and the evening (20,3%) activities. Meanwhile, shelter and wallowing activities could reduce the number of fly ectoparasite infestations in buffalo.

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.
