Evaluasi Kemampuan Lahan di Desa Sungai Jelayan Kecamatan Kedawangan Kabupaten Ketapang

Sungai Jelayan Village is one of the villages in Kendawangan District, Ketapang Regency, which still has the potential for sustainable management. Evaluation of land capability is one of the efforts to overcome the reduction of land degradation. Land capability is an assessment of land units for particular uses, assessed from each inhibiting factor. This study aimed to determine the characteristics of the land according to the land capability parameter, assessed the land capability sub-class, and provided suggestions for land use based on the land capability sub-class in Sungai Jelayan Village. The research stages started from preparation, preliminary survey, determination of research location based on land units consisting of soil type, slope class, land use and there were 9 land units, and determination of observation points, as well as field observations and soil sampling, laboratory analysis, data processing and presentation of results. The results obtained 2 soil orders, namely Entisols and Inceptisols. The results of the land capability evaluation were divided into five land capability classes and sub-classes, namely class II-s, III-s, IV-w, V-w, and VIII-es. Improvement efforts or efforts to use land sustainably could be carried out in 5 ways, namely intensive cultivation, moderate cultivation, limited cultivation, nature reserves/protected forests, and intensive grazing.

Tina Wai watershed area 48,132 ha, located in the South Buru and serves as a provider of water for the local community. Land Capability Evaluation and Tina Wai Watershed Land Use in South Buru, Maluku Province, has been performed in order to determine the land capability classification level, and determine the direction and pattern of land use in accordance with their respective land capability class. The research method is a survey method with a pattern of synthetic and analytical approach with a flexible range of observation following the change in shape of physiographic and land use. The results found that Tina has 6 Wai watershed land capability class, ie class III, IV, V, VI, VII, and VIII with factor inhibiting dominated by undulating slopes to very steep, erosion rates to very heavy weight, medium texture soil, permeability rather fast to slow, moderate sensitivity to erosion, rock gravel of moderate-to-many, and the threat of flooding rather frequently. Land capability class has the most extensive is the fourth grade with an area of 24.636 ha, or 51.19%. Referrals for agricultural land use is 29,184.75 ha or 61.89; for plantations, livestock and forest production by 8396.75 ha or 17.38%; for the protected forest of 6,941.25 ha or 14.42%; and for the nature reserves of 3036.00 ha or 6.31%.

Capability Evaluation

Researchers have attempted to incorporate environmental variables into the land-use planning process by use of several ranking and mapping formulations. Most of these are based on some type of classification scheme. More recently, multivariate statistical techniques have been utilized to classify land areas into groups with similar suitability for urban development. A test was made of one of these numerical taxonomic techniques on a data set from Medford Township, New Jersey, and the results analyzed in terms of the pros and cons of these methods. A group of 484 forty-acre grid cells with forty-two environmental variables was collapsed into a ten variable set for ten groups of grid cells having like characteristics. The analysis involved two steps, factor analysis followed by a euclidean-distance-classification algorithm. The results show that numerical taxonomy can greatly facilitate the analysis of large environmental data sets and can help to identify the ecological relationships in quantitative terms. However, the complexity of the statistical methods involved greatly limits the wide application of these techniques, and the use of numerical taxonomic results in land-capability evaluation cannot release the researcher from making many judgmental decisions.

Capability Evaluation

An assessment of the suitability of the arable land in the Dobrich region for its effective agricultural use has been prepared using an eight rate classification where the land valuation strategy guarantees the conservation of natural resources, with particular attention to erosion as a limiting factor. Maps of the area with Land Capability evaluation classes for effective agricultural and erosion control land use and the actual risk of water erosion have been developed.This allows the use of an integrated approach to the definition of soil protection measures - taking into account both soil constraints (labeled with subclass land) and the need for prevention against erosion processes. A set of different soil protection practices is recommended, each determined according to the specific soil, topographical and climatic features of the studied area, determined by the class and subclass of the land and depending on the degree of erosion risk and the way of land use (defined by Physical Blocks, 2016). The agronomic assessments according to the soil and climate conditions of the main agricultural crops are lnked to the detailed large-scale database created in the GIS format and the most suitable places for their cultivation on the territory of the Dobrich region have been identified. The agronomic fitness of arable land for the cultivation of wheat, maize, peaches and vines is assessed. Maps for the degree of their agronomic fitness were prepared. It is clear that almost all of the entire territory has a very good and good land for cultivation of these crops.
