Abstract

This research aims were to collect the diversity of natural enemies lived in rice agroecosystem and to observe which management system of rice agroecosystem can conserve natural enemies.There were two kinds of rice agroecosystem observed in this research, multicropping system (surjan system) and monocropping system (non surjan system). There were two parts of surjan fields, aquatic lower part planted with rice and terrestrial higher part planted with vegetables. The surjan fields were different from non surjan fields that were planted with rice only. Non surjan fields were had one part, that was  aquatic part. Natural enemies collecting of surjan fields and non surjan fields was done to get conclusion that which system conserved natural enemies more. This researh  results were : (1) Surjan fields had more kinds of natural enemies than non surjan fields; (2) The management system of rice agroecosystem that conserved natural enemies more was multicropping system in surjan fields.

Abstract

The study was aimed at fi nding out the abundance of aquatic weeds in Rowo Jombor, the population of Aedes spp live in aquatic weed area, and the distribution pattern of dengue fever disease related to the population of aquatic weed and Aedes spp. Field survey was conducted for two months to collect the weed population data, mosquito larvae density, and environmental sanitation condition of the villages around Rowo Jombor. The study used quantitative descriptive analysis to see the correlation among weed density, Aedes spp population. The interview was conducted to make its distribution pattern.The results show that: (1) the density of aquatic weeds in Rowo Jombor was dominated by Eichornia crassipes mainly on Location V near he outlet, while the Location III which was located in the center of the swamp, the aquatic weed was not found; (2) the larvae of Aedes spp population which lived in aquatic weed area was not found; and (3) the result could not prove the relationship between the pattern of dengue fever disease distribution and the aquatic weeds in Rowo Jombor as the habitat for mosquito larvae of Aedes spp.
