Abstract
Soil organisms or commonly referred to as soil biota are all living things, which all or part of their life phases are in the soil or ecosystem. An ecosystem requires a balance between organisms that live in that place so that the mutualism symbiosis goes well, if there is no balance, various problems will arise such as pests and diseases that have a detrimental impact on the rice cultivation process. The purpose of this study was to determine the effect of tillage technology, and irrigation and their combination on the number and diversity of macro-organisms at a depth of 20 and 30 cm. This research was carried out in rice fields on Jalan Tondano Eris, East Tondana District, Minahasa Regency, North Sulawesi Province, using a randomized block design (RAK) as an environmental design and a split-plot design as a treatment design. Treatment of tillage (T) as the main plot with two factors: T1 = Perfect Soil Tilling (OTS), T2 = Minimum Tillage (OTM). Irrigation as a sub-plot (A) with three factors: A1 = Flooded irrigation ± 5 cm, A2 = Beselang irrigation and A3 = Macak-macak irrigation. Thus there were 6 treatments and each treatment was repeated three times so that there were 18 experimental units. The parameters observed were the number and diversity of species of macro organisms at a depth of 20 cm and 30 cm. The results showed that intermittent irrigation technology had a significant effect on species diversity and the number of macro organisms at 14 WAP and 34 WAP at a depth of 20 cm but had no significant effect on observations at 21, 42 WAP and on all parameters at a depth of 30 cm. influenced the diversity of species of macro organisms at 42 WAP observations and had no significant effect at 14, 21 and 34 WAP and all parameters at a depth of 30 cm, tillage technology and the combination of tillage technology and irrigation technology did not have a significant effect on all parameters both in the soil 20 cm and in the soil 30 cm.
