Judul: Resistansi Escherichia coli yang Diisolasi dari Kucing di Klinik Hewan Kota Depok Terhadap Antibiotik
Abstrak: Kejadian resistansi antibiotik pada Escherichia coli pada hewan kesayangan sangat erat kaitannya dengan penggunaan antibiotik yang tidak tepat dalam waktu panjang dan tidak terkontrol. Penelitian ini bertujuan mengetahui gambaran resistansi E. coli yang diisolasi dari kucing rawat inap di klinik hewan Kota Depok terhadap antibiotik amoksisilin, gentamisin, sefotaksim, enrofloksasin, dan doksisiklin. Uji kepekaan antibiotik pada penelitian ini menggunakan metode Disk Diffusion Kirby-Bauer. Didapati sebanyak 12 isolat merupakan Escherichia coli. Hasil uji menunjukkan sampel resistan terhadap doksisiklin (sembilan isolat), amoksisilin (lima isolat), dan sefotaksim (lima isolat). Hasil intermediet ditunjukkan oleh amoksisilin dan sefotaksim, 16.7% resistan terhadap gentamisin, dan 8.3% resistan terhadap enrofloksasin. Escherichia coli pada penelitian ini masih cenderung sensitif terhadap gentamisin dan enrofloksasin., Antibiotic resistance in Escherichia coli in pets is closely linked to the long term and uncontrolled use of antibiotics. The study aims to determine the resistance of isolated E. coli cats in the City Depok veterinary clinic to the antibiotics amoxicillin, gentamicin, cefotaxime, enrofloxacin, and doxycycline. Antibiotic sensitivity test in this study using the Kirby-Bauer Disk Diffusion method. Twelve isolates were found to be Escherichia coli. The test results showed samples resistant to doxycycline (nine isolates), amoxicillin (five isolates), and cefotaxime (five isolates). Intermediate results were shown by amoxicillin and cefotaxime, with 16.7% resistance to gentamicin, and 8.3% to enrofloxacin. Escherichia coli in this study still tends to be sensitive to gentamicin and enrofloxacin.

Judul: Antibiotic Resistance in Escherichia coli from Cats at Several Veterinary Clinics in Bogor Regency.
Abstrak: Escherichia coli menjadi penyebab beberapa jenis penyakit pada kucing. Infeksi bakteri ini dapat menyebabkan pyometra, septikemia, Urinary Tract Infection (UTI), dan diare. Penelitian mengenai resistansi E. coli terhadap antibiotik pada kucing belum pernah di lakukan di Kabupaten Bogor. Penelitian ini bertujuan untuk mengisolasi dan identifikasi serta menguji resisitansi E. coli pada pasien kucing di beberapa klinik hewan di Kabupaten Bogor. Sampel yang digunakan adalah swab rektal dari 30 pasien kucing pada lima klinik hewan di Kabupaten Bogor. Metode yang digunakan pada penelitian ini meliputi pengambilan sampel, isolasi dan identifikasi, serta uji resistansi antibiotik mengikuti metode Disk Diffusion Kirby-Bauer yang mengacu pada Clinical and Laboratory Standards Institute guidelines (CLSI) tahun 2021. Hasil penelitian menunjukan bahwa 19 isolat E. coli berhasil diisolasi. Escherichia coli resistan terhadap eritomisin 100% (19/19), metronidazol 94,8% (18/19), dan ampisilin 57,9% (11/19). Persentase resistansi rendah terhadap amoksisilin-klavulanat 21,05% (4/19), gentamisin 15,18% (3/19), doksisiklin 15,18% (3/19) dan enrofloksasin 21,05% (4/19).

Judul: Utilization of terra/MODIS L1B data for analysis of horizontal wind profile in the troposphere
Abstrak: This study was concerned with horizontal wind derived from data collected with the Moderate-resolution Imaging Spectroradiometer (MODIS) on board the NASA’s Earth Observation System (EOS)-Terra satellite. The aim of this study is to develop a method for the estimation of horizontal wind movement in the troposphere based on Navier-Stokes equation. The method was applied to a calibrated and geolocated Terra/MODIS L1B 1 km data set. The data inputs to estimate surface temperature are retrieved from TIR (Thermal Infrared) bands 31 (10.780 μm to 11.280 μm) and 32 (11.770 μm to 12.270 μm). The obtained surface temperatures were later used to approximate geopotential height on a constant-pressure surface by using the modified Poisson equation. The main assumptions used are the hydrostatic equilibrium, ideal gas law, constant lapse rate and constant acceleration of gravity. Based on the distribution of geopotential height, the pressure gradient force is measured by the gradient of geopotential on an isobaric coordinate to present the horizontal wind profile. For certain topographic areas especially in the mountain ranges, there was a disadvantage of using pressure as a vertical coordinate which lead to inaccuracy. In spite of that, Terra/MODIS L1B data with 1 km spatial resolution can be used to estimate the horizontal wind movement in the troposphere.
