Judul: Karakteristik Habitat Larva Anopheles sundaicus dan Kaitannya dengan Malaria di Lokasi Wisata Desa Senggigi Kecamatan Batulayar Kabupaten Lombok Barat
Abstrak: Malaria adalah penyakit infeksi yang disebabkan oleh parasit Plasmodium yang ditularkan ke manusia oleh nyamuk Anopheles betina. Nyamuk Anopheles memerlukan tempat untuk berkembang biak, tempat untuk mencari darah dan tempat untuk beristirahat bagi kelangsungan hidupnya. Habitat larva A. sundaicus secara umum berada di pesisir pantai dengan karakteristik berupa air payau. Ekologi desa Senggigi berupa pesisir pantai, garis pantainya terbentang hampir sepanjang 10 km. Kawasan pariwisata pantai Senggigi menjadi ikon pariwisata di provinsi Nusa Tenggara Barat (NTB). Wisatawan asing maupun domestik banyak berkunjung untuk menikmati keindahan pantai Senggigi. Di wilayah puskesmas Meninting Kecamatan Batulayar, AMI pada tiga tahun terakhir berturut-turut adalah 6,84o/oo pada tahun 2006, 18,42o/oo pada tahun 2007 dan 9,47o/oo pada tahun 2008. Penilitian ini bertujuan untuk mendapatkan informasi karakteristik habitat larva A. sundaicus di lokasi wisata desa Senggigi Kecamatan Batulayar kabupaten Lombok Barat.

Judul: Karakteristik Habitat Larva Anopheles sundaicus dan Kaitannya dengan Malaria di Lokasi Wisata Desa Senggigi Kecamatan Batulayar Kabupaten Lombok Barat
Abstrak: Malaria is caused by Plasmodium parasites that are transmitted by female Anopheles mosquito. The immature stadium takes place on water. Anopheles larval habitats have different characteristics on fresh water and brackish water that are directly related to the soil. Senggigi village is a tourist location which is visited by many foreign and domestic tourists. The ecology of this coastal area is in accordance with the ecological habitat of the Anopheles sundaicus larvae. This exploratory research was conducted to obtain presence information, distribution and characteristics of the habitats and the density of larvae A. sundaicus at Senggigi village of Batulayar District - West Lombok. Two types of larval habitats found in this areas were estuaries and lagoon. The situations in those habitats relatively was exposed direct sunlight. Areal the bottom was sandy mud with some extensive gravel. The water quality had a temperature range between 24,80-28,10oC, salinity 0,00-2,00o/oo and pH of 7,00-8,00 which provided a supportive environment for the proliferation of A. sundaicus larval. The existence of malaria cases, A. sundaicus mosquito, and potentialy habitats were the risk factors of malaria transmission to the local communities and tourists.

Judul: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
