Judul: Studi Kasus Interpretasi Radiografi Gangguan Sistem Kardiovaskular Pada Anjing Di Klinik Hewan My Vets Bumi Serpong Damai Dan Kemang Selatan
Abstrak: This study was aimed to present radiographic interpretation of cardiovascular system disorder in dogs at My Vets Animal Clinic Bumi Serpong Damai Tangerang and Kemang Selatan. Radiographical interpretation was using Röntgen pictures from 7 dogs including their medical records. Parameters examined were VHS (Vertebrae Heart Size) measurement, dorsoventrally or ventrodorsally heart size to thorax cavity measurement, and enlargement of heart chamber. Furthermore, the other parameters that also performed in this study were enlargment of main blood vein measurement which was aorta, main pulmonary artery, caudal of vena cava, and lungs surface scoring. Main changes found were pulmonary vein dilatation which was found in all cases. Alveolar pattern change, air bronchogram, was found in 86% cases of lungs surface scoring. Main vein dilatation cases were 56% of all cases examined. Heart enlargement was found in 2 dogs. Along with those findings, another radiographic changes were also found with variying frequency. All radiographic findings on the cardiovascular system disorder described above lead to make a specific diagnosis and differential diagnosis of certain diseases that were discussed in depth in this study.

Judul: Studi Kasus Kelainan Regio Abdomen Anjing Melalui Interpretasi Radiografi di Klinik Hewan MyVets Kemang dan Bumi Serpong Damai
Abstrak: The aim of this study was to analyze abnormality and disease in abdomen region of dog by radiographic interpretation. The study was done by radiographic interpretation and confirmed with medical record that was taken from MyVets Animal Clinic Kemang and Bumi Serpong Damai. Interpretation was done by seven of basic Roentgen signs with changes of size, shape, number, location, margination, opacity, and alteration of organ function. Interpretation result was grouped by three system organ which are gastrointestinal, urinary, and reproduction system. Nine cases were taken for further discussion and compared it with literature. Abnormalities that were found in gastrointestinal system are constipation with prolaps ani, gastric foreign body, and bloating. Abnormalities that were found in urinary system are urolithiasis in urethra, renal failure, and nephromegaly with urolithiasis. Abnormalities that were found in reproduction system are dystocia fetalis, mummification, and pyometra.

Judul: Pembuatan Isoeugenol dari Eugenol Menggunakan Pemanasan Gelombang Mikro
Abstrak: Indonesia merupakan salah satu penghasil minyak cengkeh terbesar di dunia. Pasokan minyak cengkeh Indonesia ke pasar dunia mencapai 60% kebutuhan dunia. Pada tahun 2000, dari 2,080 ton minyak cengkeh yang dipasarkan, Indonesia memasok 1,317 ton (Deptan, 2005). Di negara-negara industri seperti Amerika Serikat, Perancis, Jerman, Italia, dan Inggris, minyak cengkeh digunakan sebagai bahan baku untuk membuat isolat eugenol dan derivatnya seperti isoeugenol dengan nilai tambah yang lebih tinggi. Harga eugenol sebesar Rp 75 000/kg, harga isoeugenol sebesar Rp 95 000/kg (Indesso, 2006) sedangkan harga minyak daun cengkeh Indonesia di pasar Internasional sekitar Rp 25 000/kg (Deptan, 2005). Isoeugenol merupakan senyawa yang banyak digunakan sebagai campuran dalam fragrances dan dalam produk-produk konsumsi harian seperti parfum, produk perawatan kulit, deodoran, sabun, shampo, deterjen serta sebagai bahan intermediet dalam produksi vanilin sintetik. Isoeugenol dihasilkan dari reaksi isomerisasi eugenol. Reaksi isomerisasi eugenol umumnya dilakukan dengan cara mereaksikan eugenol dalam larutan basa KOH atau NaOH pada suhu tinggi selama 5 – 7 jam (Cerveny et al., 1987). Lamanya waktu pemanasan konvensional ini diduga dapat dipersingkat dengan menggunakan pemanasan gelombang mikro. Aplikasi katalis basa yang membutuhkan jumlah yang berlebih dalam reaksi isomerisasi juga dapat digantikan dengan menggunakan katalis RhCl3.3H2O dalam jumlah yang lebih rendah (Chalk, 1977).
