Judul: Kajian entomologi dan deteksi virus dengue pada Aedes spp. serta perilaku masyarakat di Keluarahan Bantarjati Bogor
Abstrak: Dengue Haemorrhagic Fever (DHF) is a desease which caused by dengue virus (DEN). DEN virus has four types, DEN-1, DEN-2, DEN-3 and DEN-4. They are associated with antigen. This arbovirus is transmitted by Ae.aegypti dan Ae. albopictus mosquitoes in many urban areas, especially in tropical and subtropical area. DHF still becomes healthy problem at Bantarjati village in Bogor city, because the sufferer of the desease can be found all year with the highest number of cases in Bogor city. The high of DHF cases at Bantarjati village is associated with the presence of DEN virus which is maintained in the vector Aedes spp. mosquito. Until now, serotype virus which contain in Aedes spp. mosquito at Bantarjati village Bogor city was not known, there were not data or research about identification serotype dengue virus of Aedes spp. mosquito. The aims of this research are to examine bioecology of Aedes spp. mosquito, to detect the presence of DEN virus in Aedes spp. mosquito and to study about behaviour of the community in DHF endemic area at Bantarjati village in Bogor city. This research was done on April 2012 until july 2012. This research used method survey on field for 4 months by conducting a survey in the home at 06.00 am to 06.00 pm. Survey activities on field by 1) collecting mosquito; 2) collecting larvae of mosquito; 3) trapping ovitrap; 4) detect of DEN virus and 4) studying behavior of the community. The result showed that the community used water container and non water container. Type water container more used than non water container, water container as many 298 units (75.25%) whereas non water container 98 units (24.75%). Artificial container was not found in research location. Many larvae found on non water container (60.01%) and on water container (12.20%). That index value of CI, HI and BI at Bantarjati village included in group population density of mosquito is average with value density in scala 2-5. Generally, the average value of ABJ in research location shows under national ABJ indicator (95 %). The matter shows that Bantarjati village still has high risc of DHF desease transmission. The community in this location has to increase eradication of mosquito breeding program to decrease risc of DHF desease transmission. The highest blood sucking activity of Ae. aegypti happened inside the house on 10.00-11.00 am (0,42 mosquito/person/hour ) and 04.00-05.00 pm (0,21 mosquito/person/hour), whereas the highest blood sucking activity of Ae. albopictus happened outside the house on 10.00-11.00 (0,42 mosquito/person/hour) and 02.00-03.00 pm (0,17 mosquito/person/hour). Behaviour rest of Ae. aegypti preferred inside the house and Ae. albopictus preferred outside the house. Dengue virus was not found in female Aedes spp. mosquito in Bantarjati village Bogor city. The behaviour of the community was categorized moderate.

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: Kekuatan Tiga Tipe Sambungan Kayu Merbau pada Lunas Luar Kapal Ikan
Abstrak: Kapal kayu terdiri dari bagian-bagian yang merupakan satu kesatuan utuh. Bagian-bagian tersebut tidak dapat dipisahkan karena antara satu bagian dengan bagian yang lainnya saling menunjang. Diantara bagian-bagian tersebut, terdapat safu bagian yang merupakan dasar penunjang dari bagian-bagian yang lain pada kapal~ yaitu lunas. Lunas merupakan bagian dilsar pada kap~ awal dari pembangunan sebuah kapal yang juga berperan sebagai tulang punggung kapal. Lunas merupakan tempat menempelnya kerangka lambung atau gading-gading. Lunas juga berfungsi sebagai penyangga badan kapal dan mnatan yang berada di dalam kapal~ Beban yang disangga oleh lunas tergantung dilri besar kapal dan berat muatan yang dibawa oleli kapaL OIeh karena itu, material lunas harus terbnat dari kayu yang kuat, agar pada saat muatan kapal penuh, lUnas mampu menyangga beban dan kapaI tidak mengalami kerusakan. Menurut BKI (1989) kayu material lunas harus termasuk dalam kelompok kayu kelas kuat satu atan di.Ja. Lunas dipasang secara horizontaI searah panjang kap~ oleh karena itu, seIain kuat, lunas juga hams terbuat dari kayu yang panjang. Saat ini terdapat kesulitan untuk mencari kayu yang panjang karena semakin berkurangnya pohon-pohon tinggi di liutan. Siilitnya mencari kayu yang panjang menyebabkan funas kapal tidak seIalu terdiri dari satu batang kayu utuli yang panjang, tetapi juga terdiri diIri dua batang kayu sejenis yang disambung dengan sambungan. Sambungan yang digunakan pada lUnas kapaI harusIah sambungan yang kuat, agar lunas tetap mampu menyangga beban kapal dan muatan kapal.
