Traditional rice transplanting system is commonly used in Indonesian rice culture. Because of several problems such as practical and economic perspective recently faced by farmer, an improvement of the system is then developed. A novel method was developed, i.e. rice direct seeding with organic planting ribbon (OPR.) reducing environmental issue. However, information regarding rice seedling emergence performance under OPR was still unclear. Thus, a study was conducted under different OPR (close and open) design and water irrigation interval management (1-5 day interval) on rice seedling emergence. Prediction of rice seedling emergence with three emergence models, i.e. Gompertz, Logistic and General Logistic were also attempted. The results indicated that seedling emergence was greater in open design compared to close design. Emergence indicators showed that seedling emergence of rice was favored more by open design than close design. The results also showed that water irrigation interval management factor was not significant on seedling emergence. Based on emergence indicators, open design of OPR with 2 day water irrigation interval is considered as best combination for rice directs seeding method with OPR. Among the tree models evaluated, the Gompertz and General Logistic gave the best fit to the most actual observed data.
