Judul: Studi Habitat Dan Perilaku Menggigit Nyamuk Aedes Serta Kaitannya Dengan Kasus Demam Berdarah Di Kelurahan Utan Kayu Utara
Abstrak: Penelitian A. aegypti sebagai vektor utama dan A. albopictus sebagai vektor sekunder bertujuan untuk mengetahui kemampuannya sebagai penyebab demam berdarah dengue. Data-data di peroleh melalui koleksi larva dan nyamuk dewasa serta kuisioner. Penelitian dilakukan di wilayah pemukiman penduduk Kelurahan Utan Kayu Utara, Kecamatan Matraman Jakarta Timur. Hasil pengamatan larva di perumahan RW.10 untuk indeks rumah (HI) = 11,5%, indeks kontainer (CI) = 6,5% dan indeks breteau (BI) = 13,3. Penangkapan nyamuk melalui metode umpan orang dalam (indoor) dan sedang hinggap A. aegypti, diperoleh hasil tangkapan tertinggi di lokasi perumahan pada bulan Mei dengan puncak aktif menggigit pada jam 08.00-12.00 dan 16.00-18.00. A. albopictus di kedua lokasi ini tidak ditemukan. Dengan metode umpan orang luar (outdoor) diperoleh hasil tangkapan tertinggi A. aegypti di lokasi sekolah pada bulan Juni dengan puncak aktif menggigit pada jam 12.00-14.00 dan 14.00-16.00. Adapun A. albopictus hasil tangkapan tertinggi juga diperoleh di lokasi sekolah pada bulan April dengan puncak aktif menggigit pada jam 08.00-10.00 dan 16.0.-18.00. Suhu di lokasi penelitian antara 29,6 -31,5°C dan kelembaban 68%-80% dengan kepadatan tertinggi A. aegypti pada bulan Mei sementara A. albopictus pada bulan Juni. Masyarakat di RW.10 Kelurahan Utan Kayu Utara hampir seluruhnya mengetahui mengenaiA. aegypti dan A. albopictus serta biologinya.

Judul: Perilaku Vektor Demam Berdarah Dengue (Aedes spp.) di Daerah Endemis Kelurahan Bantarjati Kota Bogor
Abstrak: Bantarjati subdistrict is an area that has the highest dengue cases in the city of Bogor during 2007 to 2011. The purpose of this research was to observe the behavior of biting and resting Aedes spp. Mosquito collection was done by human landing collection and resting collection from 08.00 to 17.00 in Bantarjati subdistrict during April−July 2012. The results showed that Aedes aegypti was more active indoor the house (0.24 mosquito/person/hour) than outdoor (0.16 mosquito/person/hour) with the biting activity occurred at 10.00−11.00 (0.42 mosquito/person/hour) and at 16.00−17.00 (0.21 mosquito/person/hour). While Ae. albopictus was more active outdoor the house (0.18 mosquito/person/hour) than indoor (0.05 mosquito/person/hour) with the biting activity occurred at 10.00−11.00 (0.42 mosquito/person/hour) and at 14.00−15.00 (0.17 mosquito/person/hour). Ae. aegypti was found resting more indoor the house (0.03 mosquito/house) than outdoor (0.02 mosquito/house), while Ae. albopictus was found resting more outdoor the house (0.01 mosquito/house) than indoor (0.00 mosquito/home). The result of Pearson’s correlation analysis showed that the relationship between the rainfall index with the density of Ae. aegypti (r=0.94, P>0.05), and Ae. albopictus (r=0:49, P>0.05).

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
