Abstract

Watershed is an area that has great potential for degradation. Degraded land is characterized by the loss of topsoil due to erosion. Understanding land sensitivity to erosion plays a crucial role in determining effective soil conservation methods to prevent land degradation, especially agricultural land. This study was conducted in the Bribin Watershed, Gunungkidul, with the aim of analyzing the level of land vulnerability to erosion on agricultural land. Data analysis was carried out spatially by utilizing land system maps and land cover maps. Recommendations for soil conservation on agricultural land are determined based on the level of land sensitivity that has been analyzed. Land sensitivity to erosion in the Bibrin Watershed is classified into four categories, namely very low (0.02%), low (5.03%), moderate (27.82%), and high (67.13%). Various watershed management strategies are applied by considering the level of land sensitivity. The creation of gulud terraces and the return of topsoil as well as reforestation on ex-mining land are soil conservation efforts in controlling erosion.

Abstract

This study aimed to assess the physical and chemical characteristics of soil at four different locations in Gunungkidul Regency, Yogyakarta Special Region, which are representative areas of dryland agroecosystems. The study locations included Sumberejo (Karangmojo), Bandung (Playen), Pringombo (Rongkop), and Gading (Playen). Parameters observed included moisture content, soil pH, soil consistency (dry and wet), specific gravity, organic matter content, and soil texture. The analysis results showed that the highest moisture content was found at Location 3 (8.30%), while the lowest was at Location 1 (6.25%). The soil pH ranged from 6.4–8.1, indicating a soil acidity level ranging from neutral to slightly alkaline. Soil consistency varied from slightly hard to very hard, and from sticky to very sticky under wet conditions. All locations had very high organic matter content, indicating good soil fertility potential. The soil texture was dominated by silt loam, which has a high water and nutrient storage capacity but requires proper aeration management. The results of this study are expected to form the basis for a strategy for sustainable dry land management in the Gunungkidul region.

Abstract

The government has launched a sugar self-sufficiency program to increase sugarcane production. One of the strategies is land extensification by opening and managing new areas based on land suitability that meets the growth requirements of sugarcane. This research aims to identify the land suitability in Banyuroto Village for sugarcane (Saccharum officinarum L.). The research was conducted from February to May 2024 in Banyuroto Village, Nanggulan Subdistrict, Kulonprogo Regency, Yogyakarta. This study used a descriptive exploratory method with a field survey approach to identify land characteristics and evaluate the level of land suitability. Location points were determined using a purposive method with two Land Map Units (LMU) in Sambiroto and Kesoh hamlets. Soil sampling at each LMU was carried out using simple random sampling. Rainfall and air temperature data were obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG) for the period 2019–2023. Observed land characteristics include soil texture, drainage conditions, effective soil depth, soil pH, cation exchange capacity (CEC), organic C content, total nitrogen (N-total), available phosphorus (P-available), percentage of surface rocks, and slope gradient. Calculation and determination of land suitability class, using the matching method, by comparing observed climate and land characteristics with sugarcane growing requirements based on land suitability evaluation criteria. The results show that Banyuroto Village, Nanggulan District, Kulon Progo, has an actual suitability class of S3oa,na for sugarcane cultivation, which means marginally suitable for sugarcane cultivation, with limiting factors being soil drainage and available nutrients. This is likely the cause of less-than-optimal sugarcane productivity. If improvements have been made, such as through soil cultivation (plowing), the creation of an intensive drainage system, and proper KCl fertilizer management, it has the potential to become a suitability class of S2 (fairly suitable).
