Abstract

Soil erodibility is a major factor contributing to soil erosion as well as the intensity of erosion rates. This study aims to validate soil erodibility values based on soil type maps through field measurements of erosion hazard level (EHL) within the Antrokan Sub-watershed area, Jember. Input data included digital maps comprising rainfall data (from 2004 to 2019), soil types, land use allocation, and Digital Elevation Model (DEM). Erosion rate was calculated using the USLE model, which was executed in two steps: (1) processing and interpreting erosion variables (R, K, LS, CP), and (2) calculating and classifying soil EHL. Field measurements indicated that soil erodibility value (K) is higher as compared to the value derived from the soil type maps. This discrepancy impacts the predicted erosion rate, where using measured K values resulted in the severe EHL category, with erosion rate of 1131 t.ha–1.y–1, while using K values based on soil type maps produced erosion rate of 432.2 t.ha–1.y–1, categorized as moderate level. In this sense, validation of soil erodibility data is important for predicting erosion rate using USLE method. In conclusion, the soil conservation implementation to reduce K values is necessary in the Antrokan Sub-watershed area Keywords: Erodibility, Erosion hazard level, Nomograph, Soil type, USLE.

Abstract

Irrigation plays an important factor in supporting agricultural land productivity to improve agricultural production. This is achieved by maintaining a sustainable irrigation system through an effective and efficient irrigation system. One method to asses is by using the Irrigation System Performance Index (IKSI). This study designs an information system for IKSI in the main network system. The assessment of IKSI follows PERMEN PU NO.32/2007, with parameters such as physical infrastructure assessment, crop productivity, supporting facilities, personnel organization, documentation, and P3A. The purpose of this system is to determine the operation and maintenance (O&M) strategies and non-physical management strategies. The Main Network SIG IKSI design includes functionalities such as (i) a data folder system, (ii) an imaging system, (iii) GIS, and (iv) an evaluator of physical and non physical irrigation systems. The results of the program in the Antirogo irrigation area show an IKSI the main network value for physical infrastructure of 85,0% and non physical strategies (crop productivity, supporting facilities, personnel organization, documentation, and P3A) of 70,0% until 80,0%. The results shows that the physical infrastructure needs to be carried out regularly and non-physical strategies need to be maintained and improved. Keywords: Association of Farmer Water Users, Geographic Information System, Irrigation System Performance Index, Irrigation, PAKSI.

Abstract

Cavendish bananas (Musa acuminata Cavendish) have been cultivated in Bondowoso Regency to meet local market demands. Cultivating Cavendish bananas contributes to the potential for emission from global warming (GWP) and environmental quality conditions. This research objective to determine the emission impact and improvement recommendation of Cavendish Bananas production in the Bondowoso Regency as an environmentally friendly product. This research used the Life Cycle Assessment (LCA), which has steps such as goals and scope determining, life cycle inventory, and life cycle impact assessment and interpretations. The results of this research show that in one cycle of Cavendish banana cultivation, total GWP emissions of 95,544 kgCO2eq are generated. This impact is derived from pesticides, chemical fertilizers, diesel fuel consumption, electricity consumption, solid waste, and liquid waste. To minimize these impacts, alternatives such as compost fertilizer, fermented animal feed, processed food from banana hearts, banana chips, wastewater treatment, and the use of solar panels for electricity are needed. If implemented, these alternatives can reduce total GWP emissions by 76% or 72.537 kgCO2eq compared to conventional cultivation.
