Abstract

The study area of this research focused on two areas of Nakhonsithammarat, including the Pakpanang River Basin (the east area of Nakhonsithammarat mountain range) and the area of 18 districts located in the northern provine of Nakhonsithammarat. The objectives of this study composed of presenting the database of the current palm oil supply chain though GIS and studying the optimum model of palm oil supply chain in order to support the expansion of palm oil plantation in the area of Pakpanang river basin. The method of this study is to survey the area of palm oil plantation, oil palm trading ground and crushing mills though GPS; to built the database area though GIS by overlaying the data (Overlay Technique) Layer of the spatial database. Including the distribution of oil palm trading ground to built the new supply chain model. There are three major stakeholders of palm oil supply chain including: (1) Farmer, (2) oil palm trading ground; (3) crushing mills. The factor affecting stakeholder decision to sell palm oil is the transportation distance, followed by the price. This study found that the farmer always sell the palm oil to the nearest area of the oil palm trading ground. Then the oil palm trading ground will send the consolidated palm oil to the nearest crushing mill. However, the remote distance between the oil palm trading ground will affect the quality of palm oil. Finally, we find that there are not enough buying capacity. Therefore, we should build more crushing mill in a position south of Amphur Muang which overlap with Amphur Muang, Amphur Phaphom and Amphur Pak Panang, for solving the monopoly problem, supporting of the expaned palm oil plantation, and also increasing demand of palm oil.
