Abstract

Banjir dan longsor terutama disebabkan oleh faktor alam seperti curah hujan, topografi, bentuk lahan dan kelokan sungai serta faktor manusia yang meliputi tata guna lahan dan infrastruktur. Tujuan dari penelitian ini adalah menganalisis daerah rawan banjir dan daerah rawan longsor di Wilayah Sungai Konaweha. Penelitian ini dilakukan di DAS Konaweha dengan menggunakan metode survei. Hasil penelitian menunjukkan bahwa tingkat kerawanan banjir di DAS Konaweha tersebar seluas 101.889 hektar (14,60%) 241.794 hektar (34,64%) rawan sedang dan 354.264 hektar (50,76%) merupakan wilayah yang tidak rawan banjir. Daerah dengan tingkat banjir sedang hingga rawan banjir umumnya tersebar di Kabupaten Konawe dan Kolaka Timur. Tingkat kerawanan longsor di DAS Konaweha tersebar di wilayah sesuai dengan tingkat kerawanan longsor yaitu seluas 16.632 hektar (2,38%) kategori tidak rawan, 159.073 hektar (22,79%) rawan, 115.922 hektar (16,62%) kategori kerawanan sedang, 396.388 hektar (56,79%) kawasan rawan dan 9.932 hektar (1,42%) merupakan kawasan sangat rawan longsor.Kata Kunci: Banjir, DAS Konaweha, Longsor, Daerah Rawan

Abstract

The purpose of this study is 1) to identify changes in land use through the interpretation of Landsat imagery from 2007 to 2017 in the Baubau watershed and 2) to analyze the critical level of land and land use planning through land rehabilitation techniques and land conservation. The level of critical land was analyzed based on Scoring through GIS using four types of data, namely Landsat 2017 imagery, scoring standards for critically protected forest areas, protected areas outside the forest area and cultivation areas for agricultural business. The land use plan is based on the 2017 land capability and land cover classes that are overlaid with the use zone (Space Pattern) using the ArGis 10.3 application. The results showed changes in land cover / use from 2007 to 2017 i.e. secondary dryland forests with an area of 2,830.2 ha turned into shrubs, open land, mixed bush dryland agriculture, dry land agriculture and plantations with an area of 756.77 ha (26.74%) . Plantations with an area of 814.06 ha are turned into open land, dry land mixed with bush farming and 34.17 ha (4.20%) of settlements. Shrub land with an area of 1,196.77 ha has been turned into secondary dryland forest, open land, mixed-bush dry land agriculture, dry land agriculture and plantation with an area of 717.71 ha (59.97%). Bush mixed dryland agriculture with an area of 442.73 ha turned into secondary dryland forest, open land, settlements and plantations with an area of 99.58 ha (22.49%). Dry land agriculture with an area of 1,336.3 ha has been transformed into secondary dryland forest, shrubland, mixed shrub agriculture and plantation with an area of 370.81 ha (27.75%). Rice fields with an area of 200.91 ha are plantations and settlements with an area of 8.84 ha (4.40%). Savana with an area of 165.38 ha turned into a settlement of 7.72 ha (4.67%). While the open land with an area of 49.8 ha turned into secondary dryland forest, shrubs and plantations of 24.87 ha (49.94%). The results of the analysis of critical lands show that the Baubau watershed area with a rather critical category of 2,691.25 ha (33.62%), uncritically 2,564.76 ha (32.04%), critical potential 978.55 ha (12.23%), critical 674.61 ha (8.43%) and very critical 119.04 ha (1.49%). While the direction of land structuring is categorized into nine land cover / land use classes, namely secondary dry land forest with an area of 2,558.85 ha (31.97%), plantation 840.25 ha (10.50%), dry land agriculture 447.16 ha (5.59%), reforestation 929.47 ha (11.61%), reforestation 541.67 ha (6.77%), agroforestry 120.45 ha(1,50%), rice fields 172.10 ha(2,15%), partnership patterns 1,235.17 ha (15.43%)  and settlements covering 1,158.80 ha (14.48%).Key words : Babau watershed, Critical Land, Land Arrangement Plan

Abstract

Land suitability analysis becomes important as a source of information about the distribution of land that can be developed for Paddy Rice. The objective of the study was to analyze the level and distribution of land suitability of paddy fields in South Konawe District. This research was conducted in the Sub Districts of Laeya, Palangga, Baito and Lalembuu for 3 months namely October-December 2017. The research method used was a survey method and laboratory analysis of soil samples and data analysis of soil and climate characteristics. Data analysis includes determining the type and intensity of limiting factors, suitability classes and technological recommendations for limiting the development of paddy fields. The results showed that the area of prospective locations in Laeya Sub District was 259 hectares, Palangga Sub District covering 312 hectares, Baito Sub District covering 1,021 hectares and Lalembuu Sub District covering 159 hectares. Types of limiting factors the development of paddy field were low cation exhange capacity (CEC) low N and P levels, acidic pH and moderate drainage. The land suitability class for all locations analyzed was S2 with a category suitable enough for the use of Paddy Rice. The limiting factor improvement technology recommendations were the addition of organic matter, liming, N fertilization, P fertilization and drainage channel construction. The adoption of these recommendations will increase the carrying capacity of land for the growth and production of paddy fields.Keywords:cation exchange capacity, land suitability, land quality,, limiting factors, paddy fields
