Judul: Evaluasi Kadar Kurkuminoid Rimpang Temulawak (Curcuma xanthoriza Roxb.) Menggunakan Analisis Citra Berbasis Red Green Blue
Abstrak: Turmeric (Curcuma xanthoriza Roxb.) is one of the important natural product in Indonesia. Quality of turmeric is dictated by content of curcuminoid. The curcuminoid content could be determined by spectrophotometry, titration volumetry, or chromatography, but those analytical methods are destructive to the material and need long time. One of rapid and nondestrucive method is image analysis. The objectives of this research were to evaluate content of curcuminoid using image analysis based on red green blue (RGB). Picture taking for image analysis was using USB Digital Microscope with enlargement 800x and curcuminoids were measured using spectrophotometry Uv-Vis at wavelength of 420 nm. The data showed that RGB value is equivalent with the content of curcuminoid. The result can be used as parameter to differentiate turmeric with harvest age 3, 6, and 9 months. The obtained equation of predicted content of curcuminoid is y = - 0,22 - 0,0062 R + 0,0643 G - 0,0330 B, R² = 96,1%.

Judul: Penentuan Kadar Kurkuminoid dalam Kunyit dengan Spektrofotometri Derivatif
Abstrak: Indonesia as one of agricultural countries has various kinds of plant than can be used for pharmaceutical product, including turmeric that contains curcuminoid compound. Curcuminoid has efficacy as an antihepatoxic, anticholesterol, tumor and cancer inhibiting compound. In recent years, research has been developing a simple, fast, and low-cost analysis method from spectroscopy and chemometric combination, i.e. ; derivative spectrophotometry. In this research, turmeric extraction was conducted using sonication method, and its curcuminoid content was determined using spectrophotometry method. Analysis with UV-vis spectrophotometry and high performance liquid chromatography (HPLC) were also conducted as reference methods. Curcuminoid in turmeric using derivative spectrophotometry was 14.33 mg/g whereas with UV-vis spectrophotometry and HPLC were 14.18 and 45.40 mg/g, respectively. Based on statistical analysis for these results, derivative spectrophotometry can be applied for analyzing curcuminoid content with good accuracy and precision. This developed method was cheaper, faster, and easier than the conventional method. In addition, matrices influence in samples can be reduced compared with that using conventional spectrophotometry.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
