Regional development has the aim of increasing the rate of economic growth and encouraging the rate of regional growth, in this case the regional government must first know the superior commodities in the region. On the other hand, the development and production of leading commodities in Pidie Jaya has tended to stagnate in the past decade, while the interest of the people of Pidie Jaya for the development of coffee commodities is very high. Coffee is an important export commodity for Indonesia which is able to contribute quite a lot of foreign exchange with an average export volume from 2006-2010 of 414,169.6 tons. This position shows that the role of coffee farmers in the national and local economy is quite significant. One of the efforts to encourage the rate of regional economic growth, the Government of Pidie Jaya Regency requires the development of plantation commodity- based industries in the development of its territory, namely through a smallholder coffee plantation development plan which aims to determine the level of suitability of Robusta coffee plantations in Bandar Baru District, Pidie Jaya Regency.
This study uses a descriptive survey method, namely through field survey activities and laboratory analysis. Soil sampling was carried out randomly (random sampling) on each land map unit (SPL) which was formed based on land use, soil type and slope overlay results obtained by 14 land units. Furthermore, analysis and interpretation are carried out to assess the level of soil chemical fertility. The data from the analysis of the soil samples were then used to assess land suitability and compare the characteristics/quality of the land with the requirements for growing Robusta coffee plants.
The results showed that there were 3 land suitability classes, namely S2 class consisting of 2 sub classes spread over 5 SPLs with a total area of 3,448.05 Ha. The S3 class (marginally appropriate) consists of 3 (three) sub-classes spread over 6 SPLs with a total area of 4,078.77 Ha. And the land class is not suitable (N) which is spread over 2 SPLs with a total area of 1,324.64 Ha. The actual land suitability class S2 was improved. The addition of liming, the addition of organic and inorganic fertilizers in low to moderate amounts resulted in potential land suitability with a very suitable class (S1) covering an area of
3,448.95 Ha and for the S3 land suitability class after making terracing, liming, adding Organic and inorganic fertilizers in high to very high amounts resulted in potential S2 land suitability with an area of 3,578.01 Ha for S3 land suitability class because the soil texture factor was very fine with an area of 497.76 Ha.
