Abstract

Mapping of Subak Rice Fields Based on Geographical Information Systems in Petangan Subak and Pakel II Subak in Ubung Kaja Village, North Denpasar District Subak Petangan and Subak Pakel II are rice fields that have the potential to experience land use change. Based on data from the Central Statistics Agency (BPS) of Bali Province in 2017, the area of ??rice fields in Denpasar City has decreased by an average of 31.86 ha/year or decreased by around 1.28% per year. It is feared that it will experience a decline in the next 5 years. To anticipate further land use changes, a Regional Regulation (Perda) is required for the Protection of Subak Land as an LP2B Area, and is set forth in a Detailed Spatial Plan (RDTR). The purposes of research: knowing the area of ??subak Petangan and Subak Pakel II rice fields, knowing the subak designated in the RTHK area, making a GIS based information database on the potential of subak. According to the RTRW for the City of Denpasar (2011-2031), RTHK in urban areas is at least 30% of the city area. The area of ??Subak Pakel II which is in the RTHK of Denpasar City is 28.3 ha and is designated as a sustainable subak. Based on this, it is necessary to carry out a mapping of paddy fields in Subak Petangan and Subak Pakel II so as to facilitate planning, implementation, monitoring and evaluation of LP2B. The digitization results show that the area of ??Subak Pakel II is 49 ha, while the area of ??Subak Petangan is 36 ha. The area of ??subak rice fields in the RTHK area is 35.6 ha, namely in Subak Pakel II. The area of ??subak non-rice fields in Subak Pakel II is 7.3 ha. Subak land area that is not in the RTHK area is in Subak Pakel II, which is 21 ha.

Abstract

This study aims to determine the actual and potential land suitability, limiting factors, improvement efforts and the making of suitability maps as well as land use directions for several food crops and plantations. The plants evaluated include: rice, corn, sugar palm, coffee, salak and coconut. This research was carried out in Belimbing Village starting from January 2021 to March 2021. Based on the results of overlapping soil type maps, slope maps and land use maps, four homogeneous land units were obtained. The method used is a survey, analysis and classification of land suitability by matching the quality and characteristics of the land with the requirements for plant growth that are evaluated for suitability. The evaluation results show that the actual land suitability class for several food crops and plantations is S3 (marginally suitable) to N (not suitable). The limiting factors in the study area are: temperature, rainfall, dry months, humidity, N-total, P2O5, available K, slope and erosion hazard. Improvement of land suitability class is carried out with improvement efforts, namely the provision of organic matter, fertilization, making planting terraces according to contours and land cover except temperature, rainfall (especially for plantation crops), dry months and humidity because they are permanent limiting factors. Potential land suitability classes for several food crops and plantations evaluated are S1 (very suitable) to S3 (marginally suitable), with limiting factors of temperature, rainfall, slope and erosion hazard. Recommendations for land use in BLIVSw and BLVSw are corn and BLIVKb and BLVKb are sugar palm and coconut.
