Abstract

The increasing use of natural resources due to population growth and economic development, as well as low public awareness of natural resource conservation, has an impact on accelerating damage to river watersheds. The research aims to determine the level of erosion and its distribution, permitted erosion, conservation planning in the Telagawaja Sub-watershed. The research uses a survey method in taking soil samples based on homogeneous land unit maps. Soil samples were analyzed in the laboratory, erosion calculations used the USLE method. The research results show that the Telagawaja sub-watershed has erosion levels ranging from very light to heavy (0.99-472.19 tons/ha/year). Very light erosion 0.99; 1.53; 5.36 tons/ha/year is found in Homogeneus Land Unit (HLU) I, II, and VII. Heavy erosion 186.64; 221.43; 367.14; 472.19 tons/ha/year is found in HLU V, VI, IV, III. Permissible erosion in the Telagawaja sub-watershed is 11-36.1 tons/ha/year, spread across HLU I is 12.82 tons/ha/year; HLU II of 36.10 tons/ha/year; HLU III of 21.73 tons/ha/year; HLU IV of 24.48 tons/ha/year; HLU V of 13.55 tons/ha/year; HLU VI of 11.00 tons/ha/year; HLU VII is 15.05 tons/ha/year. Conservation actions that can be carried out are by increasing the plant management factor (C) of peanuts with straw mulch of 4 tons/ha (HLU III, IV, V and VI), increasing land management actions by making terracing with medium construction benches (HLU III and IV) and good bench terrace construction (HLU V and VI).

Abstract

Tejakula District produces fruits that are very popular with the community, but production is not yet optimal because research on land suitability has never been carried out. The aims of this research are (1) to analyze land characteristics against land suitability classes, (2) to create maps of actual and potential land suitability classes, (3) to plan land use, and (4) to provide information systems. The research used a survey and Laboratorium from March to June 2024, taking soil samples. Actual land suitability class for horticultural fruits in Tejakula District is classified as marginally suitable(S3) to not suitable(N) with limiting factors of rainfall,  root condition, pH, N-total, P2O5, slope, and erosion hazard. Improvement efforts are made through soil processing, fertilizing with organic, Urea, and Phonska, improving irrigation, and making terraces. Based on the land suitability, the districts of Tejakula, as the priority, are developed to plant mango and mangosteen with quite suitable land(S2) with limiting factor temperature at Pacung, Sembiran, Bondalem, Tejakula, Tembok Village, and another Village moderately suitable(S2) with limiting factor root condition, slope. Kingfruit and Raspberryplant are quite suitable(S2) at Sembiran, Julah, Bondalem, Tejakula, Tembok village, with the limiting factor being temperature, and another Village is moderately suitable(S2) with the limiting factor being rainfall and root condition. Grape and avocado are quite suitable (S2) with the limiting factor of temperature at Pacung, Sembiran, Julah, Bondalem, Tejakula village, another village is moderately suitable(S2) with the limiting factor of root condition and slope. Land use planning by improving irrigation and applying organic fertilizer, Urea, Phonska, and making terracing.
