Judul: Reproductive Capacity of Aedes aegypti In Laboratory
Abstrak: Penelitian ini dilakukan untuk mengetahui tentang perilaku kawin, kapasitas reproduksi Aedes aegypti meliputi jumlah kelompok telur, jumlah telur, daya tetas telur, produksi telur fertil yang dihasilkan oleh nyamuk betina Aedes aegypti tanpa jantan, dan jangka hidup nyamuk Aedes aegypti. Nyamuk Aedes aegypti diperoleh dari Insektarium Bagian Parasitologi dan Entomologi FKH IPB. Penelitian ini terdiri dari tiga perlakuan. Perlakuan pertama dimasukkan satu ekor jantan dan satu ekor betina ke dalam kandang pertama, perlakuan kedua dimasukkan satu ekor jantan dan dua ekor betina ke dalam kandang kedua, dan perlakuan ketiga dimasukkan satu ekor jantan dan tiga ekor betina ke dalam kandang ketiga. Setiap perlakuan diulang sebanyak lima kali ulangan. Hasil yang diperoleh, untuk perilaku kawin nyamuk Aedes aegypti di dalam kandang yang kerap ditemui adalah posisi ventral to ventral. Pada kapasitas reproduksi terlihat jumlah kelompok telur yang dihasilkan pada setiap perlakuan tidak menunjukkan perbedaan yang nyata. Jumlah telur yang dihasilkan oleh setiap ekor betina tidak menunjukkan perbedaan yang nyata begitu pula dengan daya tetas telur yang tidak menunjukkan perbedaan yang nyata pada setiap perlakuan. Kapasitas reproduksi terkait dengan telur fertil yang dihasilkan menunjukkan nyamuk Aedes aegypti betina dapat menghasilkan telur yang fertil walaupun nyamuk jantan telah mati. Pada jangka hidup nyamuk betina tidak menunjukkan perbedaan yang nyata.

Judul: Kemampuan Reproduksi Nyamuk Aedes aegypti Berdasarkan Keberadaan Nyamuk Jantan
Abstrak: The research was conducted to determine the reproductive capability of Aedes aegypti related to the presence of male mosquitoes, that include the number of eggs, eggs groups, egg hatchability and fertility between female Aedes aegypti that lived together with the male mosquitoes during her life and female mosquitoes that lived together with the male mosquitoes until it’s first gonotrophic cycle. Mosquitoes were obtained from the Parasitology and Medical Entomology Insectarium FKH IPB. This research consisted of two treatment groups. Every treatment was repeated three times and each repetition consist of 20 females and 10 males Aedes aegypti mosquitoes. The first treatment group consist of females that lived together with males during her life. The second treatment group consist of female mosquitoes that lived together with the male mosquitoes in the same cage until it’s first gonotrophic cycle. The number of eggs and eggs groups on both treatment did not show a significant difference. Egg hatchability also did not show a significant difference on both treatments. The female mosquitoes that lived together with the male mosquitoes just until the first gonotrophic cycle was capable to produce eggs in every gonotrophic cycle due to having a spermathecae.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
