Abstract:
The objective of this thesis is to determine the relationship between the productively of tapioca flour mills and cassave-planted area in Nakhon-ratchasima province. The study methods include data collection, processing and analysis by using geo-informatics technology techniques. The productivity data were collected from 15 tapioca flour mills. Data of cassava planted areas and transportation of the 287 subdistricts were brought for network analysis using TNT-mips, by which the 15 tapioca flour mills could be categorized into 3 groups. The distance between each of tapioca flour mills withing the same group is not more than 30 kilometers, and the distance between each group and cassava planted areas is not more than 50 kilometers. The product amount of tapioca flour and the productivity power of the mills in each group were then analyzed monthly for their appropriateness and the monthly product distribution.The results shows that the total productivity of the 15 tapioca flour mills (5,553,510 tons) is higher than the total cassave supply (2,602,243 tons) from the planted areas. It is also found that there was a discrepancy between the products and their productivity. Cassava supply was highest in February and March which almost matched the procuctivity of the flour mills. The supply of the rest 10 months is so low that many of the tapioca flour mills were not in full operationThe study suggested cassava strategic planning in Nakhon-ratchasima province as follows: an increase in cassave production, education for farmers on cultivation practices, prolonging havesting period, introducting higher yield cassava species, and limitation of the number of tapioca flour mills.
