Abstract

This  study specifically aimed to:  (i) identify of pedo-agroclimate characteristics, (ii) evaluate of  potential avaibility land,  suitability  land  and  problems  for food crops development, (iii) develop planting  and land  recource  management.  This  study was conducted  on  the mainland Buton  Regency, the  used  a spatial analysis method employing GIS.   The study  results showed that: (i) the mainland Buton  regency had relatively varied characteristics of land biophysic. For climate aspects, the region had low and uneven distributed rainfall; (ii)  potential land avaibility for food crops development in study area was : 74,664.64 ha, where the land suitability level of S2 of 5,096.52 ha, S3 of 44,521.38 ha, and the rest was N1 and N2.  The Land suitability classes for crop plant in the study area were: S3 and N1 except for cassava, there were S2, S3, and N. Similar problems were found in almost all areas, i.e. high soil pH >7  -8.5 or low 4 - 4.5, P2O5 content was very low, high air humidity  > 90% or low < 30%, high erosion risk, high slope >15 - 25%, high level of surface rocks >40%, high level of surface layer >40%, very high erosion risk, very high slope >25%), shallow effective dept < 20 cm; (iii) the land resource management, suggested were  improvements: i.e: drainage system, nutrient retention through liming and addition of organic matter for CEC and pH, nutrient availability through liming and fertilization, mechanization potency on slopy area, erosion risk level through reducing erosion rate, making terrace, parallel contour planting, cover crop planting, terrace construction for rice at slopes 3 -8%  and  8 - 15%, water availability through improvement of irrigation system.

Abstract

This study aims to determine the priority scale in the management of Arabica coffee plants based on Good Agriculture Practices (GAP) to increase the production, productivity and quality of Arabica coffee in smallholder coffee plantations. The research was conducted in three districts in Enrekang Regency, namely Baroko, Baraka, and Masalle District, respectively, from December 2017 to January 2018. The research was in the form of a survey (literature study, observation, and interviews), the sample selection was carried out using purposive sampling on 30 respondents from Agriculture and Plantation Office of Enrekang Regency, Extension officers, Famers Groups, and coffee plant experts. Quantitative descriptive data analysis using Expert Choice Version 11 was conducted on the survey results for determining the priority scale of GAP components for Arabica coffee. The study results show that the priority scale of applying GAP for coffee plants in Enrekang Regency was the cultivation aspect (46.7%) consisted of pruning, fertilization both types and application method of the fertilizer, pest and disease control, and varieties. Secon priority was the aspect of post-harvest (27.9%) followed by harvest aspect of 25.5%.
