- W3138518380 abstract "Rice and fish are an important source of protein for the people of North Sumatra that can be produced from saline paddy 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 district, North Sumatera. Comparison between IR 64 paddy types with nila tilapia (Tilapia mosambicca) on two plots, in the control area and tidal area is 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. The calculation of richnesse index of Margallef (R1), Index Jaccard, Shannon-Wiener Diversity Index (H') in saline paddy fields were done. Dominant pests such as Orseolia oryzae and Leptocorisa oratorius are controlled using by environmentally friendly bioinsecticides, such as P1(Neem leaf extract 100 ml), P2 (Papaya leaf extract 100 ml), and P3 (100 ml poison yam plant extract). T-Test, Kruskal-Wallis test and correlation test showed significant differences between the abundance and the dominance of insects in the control and saline 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, Northern Sumatra." @default.
