Abstract

The major objective for studying the production of premium grade thin brown crepe (TBC-P) from GAP standard cup lumps was to encourage farmer groups to produce high-quality crepe rubber. This study selected a specific sample group to investigate the working results of GAP-cup lumps producing farmer groups. By analyzing economic value, establishing a scientific standard of TBC-P for reducing controversy from visual assessment, and connecting the market linkage, the study found that farmer groups producing GAP cup lumps were able to increase the average annual yield by 20.28%. For analyzing the economic situation, the study found that the investment of TBC-P had values of NPV greater than zero, and those of BCR and IRR were more than 1 and 7%, respectively. These indicated the worth of investment. The standardization had set the values of maximum contaminants or dirt at 0.05%, the minimum initial plasticity at 35 unit, and the minimum plasticity retention Index at 65 unit allowing tire manufacturers to accept and trust in the quality of raw materials. These creates added value and enhances the production of TBC-P toward sustainability for the rubber farmer groups in the future.
