One of problems faced by farmers in the rice cultivation with organic system is organic fertilizer limited, especially for farmers who do not have livestock. Azolla is one of materials that can be used as organic fertilizer. The aim of the research was to determine whether Azolla (Azolla mycrophylla L.) is able to meet the nutrient needs of some rice varieties on organic rice cultivation. The experiment used factorial complete randomized block design with three factors and three replications. Azolla was spread at days after transplanting and at 25 days after transplanting, 75% of Azolla was incorporated into soil and the rest was left up until rice were harvested. Meanwhile, cow manure was distributed after tillage. The treatment consisted of rice varieties (Mira1, Mentik Wangi and Red and White), Azolla (0 and 2 tons / ha) and manure (0 and 10 tons / ha). The result showed that Azolla did not significantly increase growth and yield of rice, despite it could increase the N uptake 5,4% and P uptake P 17,3% , weight of dry straw, dry grain and 1,000 seeds by 5,86%, 12.7%, 7.37% than without Azolla respectively. Azolla 2 tons/ha with manure 10 tons/ha were able to increase N uptake by 7.6%, the uptake P by 13.7% and the of productive tiller number by 9.88%. From the standpoint of crop yields with organic system, a single use of Azolla has not been able to replace manure.

This study aims to describe in general the performance of Wonolangan Sugar Factory and to analyze the comparison of sugarcane farming with a non-sugarcane commodity in the working area of Wonolangan Sugar Factory. Wonolangan Sugar Factory is located in Probolinggo Regency, almost 90% of sugarcane raw material is obtained from Lumajang Regency. Commodities that become competitors and the main choice of farmers to be cultivated are rice, maize, and onion. The data used in this study are primary and secondary data. The sampling method used is purposive with in-depth interview technique. Portrait performance of Wonolangan Sugar Factory in the last 5 years is very fluctuating caused by various factors such as climate impacts that are less supportive, the motivation of farmers to grow sugarcane, government policy in the sugar industry. To maintain the smoothness of the mill in the implementation of milling, Wonolangan Sugar Factory has several strategies both on the farm (garden) and off-farm (sugarcane processing at the factory). Based on the comparison of Sugar Business Result (SHU) of sugarcane and non-sugarcane planting pattern, it appears that the analysis shows that sugarcane farming with one Ratoon Cane (RC) category in paddy field can only compete with the pattern of non-cane maize farming throughout the year in South Sugar Factory Wonolangan.
