SISTEM MINA PADI DI DESA MANIK RAMBUNG MENDUKUNG KETAHANAN PANGAN SUMATERA UTARA
Abstract: Rice and fish have
been an essential part of the life of Indonesian people which produce from rice
field. The research was conducted during two years (Dec.2008 to Sept.2010)
using a purposive random sampling using three plots in lowland and terrace from
Manik Rambung Rice Field (MRRF). Two types of rice crops (Ciherang and IR 64)
are cultivated showed 6 orders, 21 families, 34 taxa and 25 species.
Oligochaeta, Ephemeroptera, Hemiptera and Diptera were identified respective
families, while families of Odonata and Coleoptera were further identified to
species. There are three categories of Dominance Index (DI) in rice field,
these are: D=Dominant ( 5% individual); A=Accessory (2.5% D
5% individual) and O=Occasional (2.5%
individual) with four families (Baetidae, Chironomidae, Tubificidae and
Ceratopogonidae) as ranked high on the DI list. The Kruskal-Wallis test showed
significant differences between abundance of aquatic organisms during the time
of sampling (χ2=1274.840, P=0.000), rice growing seasons (χ2=16.393,
P=0.001) and rice cultivation phases (χ2=8.618, df=4, P=0.004). The study about
fish farming produce plant and animal proteins and sustainable for food
security in Northern Sumatra.
