We have studied the arthropods biodiversity in two paddy field ecosystems, namely, paddy field ecosystem using Integrated Pest Management (IPM) system and non-IPM paddy field ecosystem. This study was conducted from April 2011 - November 2011 in three locations, that is, Pasar Kamis village and Sungai Rangas village in Banjar regency, and Guntung Payung village in Banjarbaru city, South Borneo Province. In this study, we used insect nets, yellow sticky traps, light trap and pitfall trap to get the sample or catch the arthropods in one period of planting season. The arthropods caught were then classified into some classes: pest (herbivore), natural enemy (parasitoid and predator), and other arthropods. After that, the Species Diversity Index was determined using its Shannon-Wiener Index (H), Evenness (e), Species Richness (R), and Species Similarity Index (IS). The sum of arthropods which have the characteristic of pest and parasitoid were higher in the IPM paddy fields than in the non-IPM paddy fields, and the sum of other arthropods were the same. The highest H and e values were in the IPM paddy field in Pasar Kamis village. The IS value for each three locations were 77.5% in Pasar Kamis village, 93.42% in Guntung Payung village, and 78.76% in Sungai Rangas village.Keywords: diversity, arthropods, ecosystem, and SLPHT

This research aimed to find a pattern of agroecosystem management that can increase arthropod diversity, production, and Return Cost Ratio (RCR) values in organic wetlands planted during the dry season. Â This research was set in Randomized Block Design (RAK) with seven treatments and five repetitions, namely:Â 1) Intercropping Â between green mustard Â and basil, with chicken manure and without Bacillus thuringiensis;Â 2) Intercropping between green mustard and basil with water hyacinth compost, and without B. thuringiensis;Â 3) Â intercropping between green mustard and leek, given water hyacinth compost, and without application B. thuringiensis;Â 4)Intercropping between green mustard Â and leek, given chicken manure, and without application B. thuringiensis;Â 5) Intercropping between green mustard and leek, given chicken manure, and given B. thuringensis application, doubled of recommended dosage; 6) Intercropping between green mustard and leek with chicken manure, and B. thuringensis application according to recommended dosage; 7) Monoculture of green mustard without organic fertilizer and without the application B. thuringiensis.Â From this research, it was concluded that the pattern of agroecosystem management of green mustard that can increase arthropod diversity in organic wetlands planted during dry season was the intercropping treatment between green mustard with basil, together with chicken manure and without B. thuringiensis. Meanwhile, the pattern of agroecosystem management of green mustard that can increase the production of green mustard and RCR value on the organic wetlands planted in the dry season was the intercropping treatment between green mustard with leek, together with chicken manure, and without B. thuringiensis.

Our previous studies showed that the extreme high yield tropical rice (Padi Panjang) produced 3-8 t ha-1 without fertilizers. We also found that the rice yield did not correlate with some soil properties. We thought that it may be due to ability of root in affecting soil properties in the root zone. Therefore, we studied the extent of rice root in affecting the chemical properties of soil solution surrounding the root zone. A homemade rhizobox (14x10x12 cm) was used in this experiment. The rhizobox was vertically segmented 2 cm interval using nylon cloth that could be penetrated neither root nor mycorrhiza, but, soil solution was freely passing the cloth. Three soils of different origins (Kuin, Bunipah and Guntung Papuyu) were used. The segment in the center was sown with 20 seeds of either Padi Panjang or IR64 rice varieties. After emerging, 10 seedlings were maintained for 5 weeks. At 4 weeks after sowing, some chemical properties of the soil solution were determined. These were ammonium (NH4+), nitrate (NO3-), phosphorus (P) and iron (Fe2+) concentrations and pH, electric conductivity (EC) and oxidation reduction potential (ORP). In general, the plant root changed solution chemical properties both in- and outside the soil rhizosphere. The patterns of changes were affected by the properties of soil origins. The release of exudates and change in ORP may have been responsible for the changes soil solution chemical properties.Keywords: Ammonium, electrical conductivity, iron, nitrate, oxidation reduction potential, pH, phosphorus [How to Cite: Purnomo E, D Choiron, R Yulia, H Halim, Krisdianto, A Hairani and M Osaki. 2012.
