Abstract

A research aiming to improve soil aggregate stability of Ultisol in terms of creating sustainable agriculture and environmental development was conducted by applying fresh organic matter (OM)  into soil.  Three types of  OM sources used were Titonia diversifolia, Chromolaena odorata, dan Gliricidia sepium.   This research was conducted in Ultisol Limau Manis Sumbar having annual rainfall > 5000 mm, in 2008.   The fresh OM used was cut, mixed with soil up to 20 cm depth, and then incubated for approximately one month before corn seeds were planted.  Soil was sampled before being treated with OM and then after harvesting corn (4 moths after applying OM).  Soil OM content as well as soil aggregate stability (AS) and several other soil physical properties wer analysed in laboratory.  The results showed that soil OM content and AS increased after one planting period.  Besides that, soil physical properties were also improved.  As soil physical properties became better, corn production was also higher at plot with than without OM application.  Among 3 species of OM added, Tithonia diversifolia gave highest corn biomass.  Level of land slope (0-8% dan 15-30%) did not show significant difference either for biomass or for soil OM content and soil AS.Key Words: marginal soil, green manure, soil aggregate stability, soil organic matter

Abstract

Many species of mosquito were made to bite cat which contain microfilaria of Brugia pahangi in infective stage.Microfilaria will develop to infective stage (L3) in non-cibarial armature mosquitoes and will not in mosquitoes which have cibarial armature. This period depends on the species of mosquitoes. In Armigeres subalbatus we found first, second and third stage larvae on the fourth, sixth and seventh day.Key Words: Brugia pahangi cibarial armature mosquitoes - Armigeres - Mansonia - Anopheles

Abstract

Stool specimens for microscopic examination collected from orphanages in Yogyakarta indicated the species and the overall percentages of prevalence of human intestinal parasites. These samples were examined in our laboratory by direct smear and concentration methods. The overall percentage of the sample population found infested with intestinal helminths was 43.4 and of intestinal protozoa was 39,8.KeyWords: intestinal helminths - intestinal protozoa - direct smear - Ritchie method - anal swab
