The growth of supermarket demand on fresh agricultural product affects the growing of market channel on farmers, such as what happens on strawberry farmers who joined in Asgita association. Before there is a demand from the supermarket, farmers sold their strawberries to the traditional market with a 75% ripeness level and without any post harvest processing. To supply demand from the supermarket, farmers should follow the condition that the supermarket will only accept strawberries with 90% ripeness level, which is taking longer range day, and also requires post harvest processing such as sorting, grading, packing, and chilling. Dealing with supermarket give farmers more profit than with the traditional market, yet it has a limited demand and greater risk. In complying the <br /> <br /> <br /> supermarket demand, there usually insufficient or abundant volume of strawberries on each delivery time due to the harvesting time that is done by farmer individually without any coordination with other farmers. If there is insufficient stock then farmers will face a lost opportunity to gain a greater profit, <br /> <br /> <br /> but an abundant stock also form problems in storing process as strawberries can only be kept for two days. <br /> <br /> <br /> The goal of this research is to develop a harvest schedule model for strawberries with 90% ripeness level to supply the supermarket and strawberries with 75% ripeness level for the traditional market, which is expected to maximize the total profit. The development of the model is based on the sugar harvest scheduling by Grunow, et.al (2007). In designing a longer harvest planning and dynamic condition, a rolling scheduling approach is used. The result shows that the model can determine the harvest time on each land area for the 75% and 90% ripeness level strawberries that will maximize the profit. But for the longer period of planning, the rolling scheduling approach can only show a result that near an optimal level. Sensitivity analysis shows that by the increase of supermarket demand volume, the 90% harvest volume is getting large also, as the profit is <br /> <br /> <br /> higher. On the analysis of price differences, at different supermarket price of 11,000 compared to the traditional market prices, the harvest is only scheduled for strawberries with 75% of ripeness level due to higher profits. While for the proposition change of strawberries that pass the sorting process, we find out that the bigger proposition of strawberries that pass the sorting process, the bigger profit will be gained by the farmers.
