Evaluasi Kesesuaian Lahan Untuk Pengembangan Agroforestri Berbasis Kopi Liberika Di Desa Kedabu Rapat Kabupaten Kepulauan Meranti

---

One of the plantation commodities that are currently being intensively developed in Riau Province to be precise in Kedabu Rapat Village, Meranti Islands Regency is Liberika Coffee. People in the production center of Liberika Rangsang Meranti Coffee have been cultivating Liberika Rangsang Meranti Coffee from generation to generation. They grow Liberika Coffee under shade trees, use organic fertilizers, and selectively (ripe select fruit). Sales of Liberika Rangsang Meranti Coffee have penetrated the Malaysian market since 1980, as much as 90 percent of Meranti's Liberika Coffee is accommodated by the Malaysian market, and only 10 percent has penetrated the local market. In 2018, the export of Liberika Meranti Coffee to Malaysia reached 71 tons in the form of green beans or the equivalent of 800 tons of fresh fruit. However, currently the harvest is decreasing, so that in 2019 sales are only 45 tons. The problems include, among others, the intrusion of sea water into the mainland, resulting in a higher level of underground water salinity in Kedabu Rapat Village, reduced agricultural land, inappropriate planting locations, unsuitable planting patterns and some people who are not interested in cultivating Liberika Coffee. Therefore, to improve the production of Liberika Coffee, it is necessary to conduct research the characteristics of the land, evaluate the suitability of the land and how the pattern of agroforestry development based on Liberika Coffee in Kedabu Rapat Village.
This research was conducted for 3 (three) months, from September 2019 to November 2019 in Kedabu Rapat Village, Rangsang Pesisir District, Meranti Islands Regency. The research used survey method, where soil sampling was made by transect with 1 km intervals. Characteristics and quality data of land observed directly in the field consist of soil texture and structure, peat depth, root depth, groundwater level, soil and water pH and soil and water EC. Analysis of soil samples for Organic-C (%), Cation Exchange Capacity (CEC) (me / 100 gr soil), Base Saturation (BS) (%) and Total Nitrogen (TN) was brought to the Soil Laboratory of the Faculty of Agriculture, Riau University. In order to evaluate the land suitability of Liberika Coffee, Coconut, Areca nut and Geronggang, data analysis was carried out using GIS software with scoring and matching techniques on 8 parameters of land characteristics, consisting of rainfall, flood hazard, landslide and erosion hazard, peat depth, soil pH, Organic-C, Cation Exchange Capacity (CEC) and Base Saturation (BS) with plant growth requirements. Land suitability evaluation carried out in stages will produce land suitability classes for the development of agroforestry based on Liberika Coffee with shade plants in the form of Coconut, Areca nut and Geronggang with categories S1 (very suitable), S2 (suitable), S3 (marginally suitable) and N (not suitable).

The results showed that the characteristics of the land in Kedabu Rapat Village included; the climate type is A with Q value between 0 - 14.3% with an average annual rainfall of 1,886 mm / year and an average air temperature ranging from 25.6 ° C-27 ° C, flat topography with a classification of slopes ( 400 cm), very high Organic-C and mineral soils with shallow sulfidic depth (FeS2) with mangrove vegetation, while the settlement area were ± 104.61 acre (4.29%). The pattern of agroforestry development based on Liberika Coffee with Coconut, Areca nut and Geronggang shade plants in Kedabu Rapat Village was used by applying spacing and cropping systems for Spacing of Liberika Coffee 2.5 x 2.5 m, Coconut with a spacing of 10 x 10 m, Geronggang with a spacing of 5 x 5 m and Areca nut between Coconut plants.
