Abstract: . The purpose of this research study arthropod biodiversity on local upland rice crop comes from the mountains of Meratus organically grown in the lowlands and the effect on rice plant growth. Research using survey methods with 5 (five) treatments and 4 (four) replications. The treatments were a) organic fertilizer with a dose of 2 tons per acre, b) organic fertilizer at a dose of 4 tons per hectare. c) organic fertilizer dose of 6 tonnes per hectare d) organic fertilizer at a dose of 8 tons per hectare, e) inorganic fertilization is done with a total dose of 300 kg NPK (Ponska) plus 100 kg urea/hectare. To determine the level of stability of agro-ecosystems in rice crops with organic farming systems analysis Dominance Index (C), biodiversity index (H'), level of similarity (E), and Richness index (R). From the results of research and discussion, it can be concluded that 1) organic fertilizer at a dose of 8 tonnes per hectare can be increased by the highest number of arthropods than inorganic fertilizer plots given, 2) organic fertilizer at a dose of 8 tons per hectare to improve the diversity index, the index species richness, the degree of similarity, as well as decrease the dominance index, 3) Biodiversity of arthropods are at moderate, both in plots treated with organic fertilizer and inorganic fertilizer with a range of values of diversity index 2> H '
