analysis was performed using AHP method with ratings to export plantation areas. This method uses social and economic factors.

4.5. Existing of Non Rubber
The conditions of suitable areas for rubber but planted with non rubber other commodities is shown in Table 16. Suitable areas planted with non rubber
were divided into eight conditions, namely moderately suitable S2 shrub areas existing shrub have the biggest area from the total of land about 310,526 hectares
or 29.1. This was followed by highly suitable areas planted with oil palm S1 oil palm about 13,277 hectares 1.2, moderately suitable areas planted with oil
palm S2 oil palm about 44,893 hectares 4.2, highly suitable areas planted with mixed gardens S1 mixed gardens about 77,218 hectares 7.2, moderately
suitable areas planted with mixed gardens S2 mixed gardens about 58,013 hectares 5.4, highly suitable areas existing shrub S1 shrub about 33,549
hectares 3.1 please see Figure 18, high suitable areas planted with paddy

field S1 paddy field about 77,218 ha or 7,2 and moderately suitable areas planted with paddy field about 5,801 ha or 5.4. The next step is analyzing using
AHP with ratings method, especially shrub area. Map of existing of non rubber please see Figure 17.

4.6. Development Area of Rubber Plantation
To select sub regency which has a high production potential of rubber expert judgments are required, with regard to social and economic factors. In this
analysis questionnaires are uses as a tool to get input data from four 4 experts of different disciplines scientific see Appendix 7.
From the results of questionnaires some values were obtained i.e. criteria aspect value 15 from four
experts, followed by value 3 from one expert. For the value of sub criteria social aspect is value 5 from two experts, value 15 from one expert and value 9 from
one expert. For the value of sub criteria economic aspect is value 3 from one expert, value 5 from two experts and followed by value 19 from one expert. Then
this value checked one by one for consistency of judgment. The values are combined into one value using geometric mean method.
T
he consistency ratio to determine comparisons are consistent. Consistency ratio in PCM process is mean consistency in judgments from experts
group to know about vulnerability problem. In this study, consistency ratio CR
48
has value 0.1. Criteria economy has high weight value 0.71 which means developing the economy is the most important criteria than social criteria. In
social criteria, rubber area is most important than the number of rubber farmer, with weight value of 0.72. For economy criteria, ratio income of rubber with non
rubber is most important than ratio cost of rubber with non rubber which has weight value of 0.63 see Appendix 5.
Rating models was evaluated all sub regency of Banyuasin Regency i.e. fifteen 15 sub regency. The result of rating models is shown in Table 17, in

development. The area and percent of priorities of the alternatives is shown in Table 18,
which Rantau Bayur Sub Regency S1has shrub area about 12,998 ha or 1.2, followed by Banyuasin III Sub Regency S2 has shrub area about 4,356 ha or
0.4, Betung Sub regency S2 and S1 has shrub area about 3,753 ha 0.4 and 3,584 ha 0.3, etc. The total area of priorities for rubber plantation development
is 51,960 ha or 4.87 from area of Banyuasin Regency as shown in Figure 19.
