Judul: Tempat Perindukan Vektor Chikungunya (Aedes spp.) di Kelurahan Pasir Kuda, Kecamatan Bogor Barat, Kota Bogor, Jawa Barat
Abstrak: Prevelance of chikungunya infectious disease transmitted by Aedes aegypti and Ae. albopictus vectors at Bogor is quite high and tend to become an extraordinary outbreak. Study on the breeding site of Ae. aegypti and Ae. albopictus that includes the type of material, colours, form and shape of the container both inhouse and outside house on December 2010 – March 2011 had been conducted by measuring larval index which were container index (CI), house index (HI) and Breteau Index (BI). The results showed that as much as 65,99% indoor water containers were used as breeding site and 34,01% was found at outdoor house water containers. Occurrence of Ae. aegypti was found as much as 82% indoor, while Ae. albopictus were found in outdoor house containers as much as 68,29%. Aedes aegypti was preferable water bath container made of cement with blue colour for breeding site. The three larval indeces i.e CI, HI and BI showed similiar decline changing pattern during period of the survey. Container index (CI) in Pasir Kuda village was catagorized by WHO as high density figure, while as HI and BI were catagorized as medium density figure. Number of CI of Ae. albopictus was significantly correlated with ambient temperature.

Abstrak: Chikungunya disease was one of the community health problems at PasirKuda Village with an attack rate of 2.96‰ in 2010. This research was done to study the mosquitoe ecology and to detect the presence of chikungunya virus (CHIKV) in Aedes spp. mosquitoes. Field surveys were done from December 2010 until August 2011 to collect mosquitoes and conduct interview to identify community knowledge, attitudes and practices (KAP) on chikungunya, and then in the laboratory to detect chikungunya virus in mosquito samples using Polymerase Chain Reaction (PCR) technique. The resultsshowed that Ae. aegypti breeding place was not in the collecting and saving water container inside the house, but was in another container outside, Ae. albopictus prefer to breed in natural water container and was categorized in moderate density. Ae.aegypti tend to bite and rest inside the house, while Ae. albopictus tend to bite and rest outside the house. Chikungunya virus was successfully detected only in the female Ae. aegypti which was collected on December 2010. The society’s knowledge about chikungunya prevention was categorized as moderate, however, it was not in line with their actions.

Judul: Pengaruh Nisbah Reaktan Lignin-NaHSO3 dan pH pada Produk Natrium Lignosulfonat
Abstrak: Lignin diisolasi dari lindi hitam dengan pereaksi H2SO4 20%. Sulfonasi terhadap lignin menghasilkan NaLS yang dapat dimanfaatkan sebagai zat pendispersi, pengikat, penukar ion, dan aditif pada beton. Pada penelitian ini dilakukan sulfonasi terhadap lignin dengan nisbah reaktan lignin-NaHSO3 1:0.4, 1:0.5, dan 1:0.6 dan pH awal 5, 6, atau 7. Parameter yang diamati ialah kemurnian, pH akhir, dan Rendemen NaLS. Kenaikan pH awal meningkatkan pH akhir dan rendemen NaLS, tetapi menurunkan kemurniannya. Kenaikan nisbah lignin-NaHSO3 meningkatkan rendemen dan menurunkan kemurnian, tetapi tidak berpengaruh pada pH akhir NaLS. Kondisi optimum yang dipilih pada pH awal 6 dan nisbah lignin-NaHSO3 1:0.6. Pencirian gugus fungsi menggunakan spektrofotometri inframerah menunjukkan telah terjadi reaksi sulfonasi terhadap lignin. Hal ini dapat dilihat dengan terbentuknya serapan baru pada bilangan gelombang 626 nm yang menunjukkan ikatan C–S.
