Abstract
Rice and fish are an important source of protein for the people of North Sumatra that can be produced from tidal rice cultivation. The research was conducted started from March 2017 to September 2017 using group random design method on two plots of rice plantation in Paluh Merbau Sub-district, Percut Sei Tuan, North of Sumatra. Comparison between IR 64 paddy types with nila tilapia (Tilapia mosambicca) on two plots, in the control area and tidal area are predicted to show a comparison of fish composition and diversity of species of insects identified to family/species levels categorized into 4 groups (Predators, Parasites, Pests, Parasitoids). Yellow Sticky Trap (YST) more effective used than Sweep Net (SN) and Core Sampler (CS) in Paddy of Percut. Calculation of richnesse index of Margallef (R1), Index Jaccard, Shannon-Wiener Diversity Index (H ') in tidal rice fields. Dominant pests such as Orseolia oryzae and Leptocorisa oratorius are controlled using environmentally friendly bioinsecticides, such as . T-Test, Kruskal-Wallis test and correlation test showed significant differences between the abundance and the dominance of insects in the control and tidal areas; the effectiveness of insect trap testing and the most effective use of vegetable pesticides. Furthermore, differences in insect biodiversity during the sampling period and phase of paddy were affected by physical, chemical, and biological factors in Percut Sei Tuan, North of Sumatra.
