Abstract

People's cocoa plantations in Padangguni District are generally located in a steep slope topographic condition with this condition the potential for erosion is very high which can affect land productivity in the community cocoa plantation area. The purpose of this research is to predict the actual erosion rate, determine the erosion hazard index classes, and recommend soil conservation alternatives on different slopes in smallholder cocoa plantations in Padangguni Sub-District, Konawe District. This research was conducted from October to December 2022 in Padangguni Sub-District, Konawe District. The survey method was used in this research, and the prediction of erosion rates was conducted using the USLE method on 3 land units: land unit 1 located in smallholder cocoa plantations with a slope of 6% covering an area of 14.6 ha, land unit 2 with a slope of 24% covering an area of 17.2 ha, and land unit 3 with a slope of 22% covering an area of 60.5 ha. The research results showed that the highest actual erosion occurred in land unit 3 at 1,307.74 tons/ha/year, while the lowest erosion occurred in land unit 1 at 1.12 tons/ha/year. The tolerated erosion rates were 31.61 tons/ha/year for land unit 1, 25.70 tons/ha/year for land unit 2, and 26.95 tons/ha/year for land unit 3. The highest erosion hazard index was found in land unit 3 at 48.52 tons/ha/year with a very high criteria, while the lowest erosion hazard index was found in land unit 1 at 0.04 tons/ha/year with a low criteria. The recommended soil conservation techniques to ensure the sustainability of smallholder cocoa plantations include applying vegetative conservation techniques using plant residues as mulch and mechanical methods through the construction of traditional terraces or roraks. Both scenarios of soil conservation action methods can reduce the actual erosion rate, making them appropriate choices for reducing erosion rates on cocoa plantation lands

Abstract

Petetea'a Village, North Kulisusu District, North buton Regency has potential agricultural land resources that need to be optimized for use, especially for industrial crop commodities such as field rice. This research aims to classify land suitability classes and determine limiting factors and improvement efforts to support field rice production in Petetea'a Village, North Kulisusu District, North Buton Regency. The method used in this research is a direct observation method in the field taking into account the type of soil, slope, land use and type of geology, while the observation method used is drilling. Data from field observations and the results of soil sample analysis in the laboratory were assessed for land suitability using a matching method with plant growth conditions. Of the research show that the land suitability class for fiel rice commodities in Petetea’a Village, North Kulisusu District, North Buton Regency in the quite suitable class (S2), namely in land unit 1, namely in land unit 6 with limiting factors for rooting media, flood danger, land preparation and nutrient retention. The marginal appropriate class (S3) in lan unit 2 has limiting factors in rooting media, land preparation and nutrient retention.land unit 4 is rooting media and nutrien retention, land unit 5 is rooting media and limiting factors in the unsuitable land suitability class (N) in land unit 3 is rooting media and land unit 7 is rooting media and flood hazard. These limiting factors can generally be repaired through efforts to create drainage channels, adding organic materials, planting cover crops on land with a slope of >40 %. This improvement effort increases the suitability class of the land potentially to be quite suitable (S2) on land units 1 and 6, marginally suitable (S3) on land units 2 and 4 and not suitable (N). on land units 3,5 and 7
