Abstract

Shallot is an important horticultural commodity. Shallot production is influenced by variety, planting material, environment, growing media, and nutrient availability. Optimal sunlight intensity and appropriate nutrient types are essential to achieve high yields. Adequate nutrients can be obtained through the application of animal manure to the growing media. This study aimed to determine the effect of shading and types of animal manure on the yield of Lokananta shallot variety from True Shallot Seed (TSS) grown in Ultisol soil. The research was conducted on Ultisol soil in Pangkalpinang City, Bangka Belitung Islands Province, from April to September 2024. A split-plot design arranged in a Randomized Complete Block Design (RCBD) was used. The main plot was shading treatment (with shading and without shading), and the subplot was types of animal manure (chicken, cattle, goat, swiftlet, and bat manure). Data were analyzed using Fisher's test and the Honestly Significant Difference (HSD) test at a 95% confidence level. The results showed that the treatment without shading produced the best agronomic characteristics of TSS-grown shallots in terms of number of leaves, number of tillers, stem diameter, and number of bulbs across different animal manure types in Ultisol soil. The combination of chicken manure and no shading yielded the best plant characteristics in terms of number of leaves, number of tillers, fresh weight, and dry weight in Ultisol soil. The application of chicken manure showed superior performance in number of tillers, stem diameter, and fresh weight.

Abstract

Land use conversion in the hilly area of Wonosalam, Jombang Regency, has significantly altered vegetation cover, leading to increased soil erosion rates. This study aims to analyze soil erosion magnitude across various land use types and assess the impact of land conversion on erosion levels in Wonosalam Village in 2014, 2019, and 2024. A quantitative approach was applied using the Universal Soil Loss Equation (USLE) model combined with spatial analysis through Geographic Information System (GIS). Data sources include Landsat 8 imagery, land use maps, rainfall data, slope maps, and laboratory analysis of soil physical and chemical properties. Each erosion factor (R, K, LS, C, and P) was analyzed to estimate soil loss (A) in tons/ha/year. The results indicate that the conversion of forest areas into agricultural and residential lands significantly increases erosion rates, especially on slopes steeper than 25%. Conversely, forested areas with dense vegetation show the lowest erosion rates. These findings demonstrate a strong correlation between land use change and erosion acceleration. The study provides valuable insights for soil conservation planning and sustainable land management in the hilly regions of Wonosalam
