Judul: Infestasi cacing parasitik pada harimau (Panthera tigris) di Taman Rekreasi Margasatwa Serulingmas, Kebun Binatang Bandung, dan Taman Safari Indonesia
Abstrak: Penelitian ini dilakukan untuk memeriksa keberadaan dan jenis cacing parasitik pada harimau (Panthera tigris) di Taman Rekreasi Margasatwa Serulingmas, Kebun Binatang Bandung, dan Taman Safari Indonesia. Sebanyak 35 ekor harimau yang diperiksa dari tiga lembaga konservasi eks situ, yaitu 4 ekor harimau benggala dari TRMS Serulingmas, 12 ekor (4 ekor harimau benggala dan 8 ekor harimau sumatera) dari Kebun Binatang Bandung, dan 19 ekor (4 ekor harimau benggala dan 15 ekor harimau sumatera) dari Taman Safari Indonesia. Semua sampel tinja yang diperoleh kemudian diperiksa melalui metode pendekatan kualitatif (pemeriksaan natif, pengapungan, dan sedimentasi) dan kuantitatif (menggunakan kamar hitung McMaster) guna mengetahui keberadaan telur cacing parasitik. Selain itu dilakukan pemupukan pada tinja yang positif terdapat telur strongyloid dan Strongyloides. Cacing parasitik yang ditemukan dari hasil penelitian adalah Toxocara, Toxascaris, Ancylostoma, Strongyloides, Trichostrongylus, Cooperia, dan Oxyuridae. Cacing Toxocara, Toxascaris, Ancylostoma, dan Strongyloides bersifat zoonosis. Berdasarkan hasil penelitian, dapat disimpulkan bahwa prevalensi kecacingan pada harimau di TRMS Serulingmas 100%, di KBB 50%, dan di TSI 47,4%. Cacing parasitik yang terdapat pada harimau di TRMS Serulingmas adalah Toxocara, Ancylostoma, Strongyloides, Trichostrongylus dan Cooperia. Cacing parasitik yang terdapat di KBB adalah Toxocara, Toxascaris, Ancylostoma, Trichostongylus, dan Oxyuridae. Cacing parasitik yang terdapat di TSI adalah Toxocara, Toxascaris, Ancylostoma, dan Oxyuridae.

Judul: Infeksi Cacing Gastrointestinal pada Harimau Sumatera (Panthera tigris sumatrae) di Taman Margasatwa Ragunan
Abstrak: The aim of this research was conducted to investigate the prevalence values and the intensity of infection of gastrointestinal helminths from Sumatran Tigers (Panthera tigris sumatrae) in Ragunan Zoo. A total of 26 individual stool samples were collected from 26 tigers at 4 areas. These samples were examined using modified McMaster, simple floatation, and modified sedimentation techniques based on sex and age group. The result showed that the identified helminth eggs were Toxocara cati and Toxascaris leonina (Ascarid) and also Ancylostoma tubaeforme (Strongylid). There were 25 (96%) of the examined animals infected by Ascarid (96%) and Strongylid (68%). All male tigers (100%) were infected by Ascarid and 64% were infected by Strongylid. There were 83% female tigers infected by Ascarid and 67% infected by Strongylid. The prevalence of the age group of <5, 5-10, and >10 years old, consecutively indicated that 100%, 91%, and 83% were infected by Ascarid and 67%, 64%, and 67% were infected by Strongylid. The highest intensity of Ascarid infection (10625 EPG) was found in females while the highest intensity of Strongylid infection (3650 EPG) was found in males. Those intensity of infection were found in the age group of <5 years old.

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.
