Judul: Studi Habitat dan Perilaku Menggigit Nyamuk Aedes serta Kaitannya Dengan Kasus Demam Berdarah Di Kelurahan Utan Kayu Utara Jakarta Timur
Abstrak: This study was aimed to asses the potency of A.aegypti and A. albopictus as the primary and secondary vectors of dengue fever. The data were gathered through adult and larva collection of mosquitoes and method of interview. The area observation was at Utan Kayu Utara village, Matraman subdistrict, East of Jakarta. Method of research was an observation of larvae and the results showed house index (HI) rate was 11.5%, container index (CI) rate was 6.5%, and Breteau index (BI) rate was 13.3 %. Method of biting rate index (indoor) and house density index of A. aegypti was the highest on May compare to the other months. Peak activity was the highest on 08.00-12.00 am and 04-06 pm. The population of A. aegypti was also dominant compare to A. albopictus at human dwelling. Method of biting rate index (outdoor) of A. aegypti was the highest on June and peak activity was the highest on 00.00-02 pm and 02-04 pm .A. albopictus was the highest on April and peak activity was the highest on 08.00-10.00 am and 04-06 pm. The population of A. albopictus was also dominant compare to A. aegypti at school building. The occurrence and the behaviour of A. aegypti was on May at 29.6 -31,5°C and RH 68%-80%. The inhabitants of Utan Kayu are mostly familiar about both A. aegypti and A. albopictus and their biology.

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: 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.
