Abstract

Erosion is the process of soil or soil particles being moved from one place to another by water. In the context of a watershed, erosion is a significant issue because it reduces soil productivity and increases sedimentation, thus reducing the lifespan of reservoirs. The goal of this research is to assess the predictive value of erosion in the Alue Geudubang Sub-watershed, North Aceh Regency. The research methodology involves a survey which includes a preparation stage, preliminary survey, main survey, data analysis, and presentation of results. Erosion prediction is calculated using the Universal Soil Loss Equation (USLE). The research findings indicate that the highest erosion prediction value is at SPL 10, where low-density mixed garden land, 0-8% slope, and Inceptisol soil type result in a value of 327.57 tonnes/ha/yr (ETol = 26.78 tonnes/ha/yr). Meanwhile, the lowest erosion prediction value is found at SPL 1 with forest land use, 0-8% slope, and Ultisol soil type, yielding a value of 5.01 tonnes/ha/yr (ETol = 16.17 tonnes/ha/yr). The recommended soil conservation technique for SPL 10 is to improve cropping patterns, such as planting high-density patterns combined with creating plant beds, to reduce the erosion rate to 9.83 tonnes/ha/yr (ETol = 26.78 tonnes/ha/yr).

Abstract

The purpose of this study was to determine the effect of the comparison of soaking concentrations of GA 3 on the viability and vigor of seeds of two varieties of papaya. The experiment was carried out in the laboratory and screen house of the Food Crops and Horticulture Seed Supervision and Certification Center (BPSBTPH) of the Food Crops and Horticulture Service, Jawa Barat Province, Bojongsoang, Bandung Regency, at an altitude of 630 m above sea levels from April to May 2023. The design used was an environmental design using a two-factor Split Plot Design which was repeated three times. The first factor as the main plot was the variety consisting of two stages including v1 (Callina variety) and v2 (PY ASA 01 variety). The second factor as a plot for comparison of GA3 concentrations contained 5 levels including k0 (0 mgL-1 water), k1 (50 mgL-1 water ), k2 (100 mgL-1 water), k3 (150 mgL-1 water), k4 (200 mgL-1 water). The experimental results showed an interaction between soaking concentration of GA3 and variations in germination rate, germination rate, root length, plant vitality, and plant dry weight, but no interaction occurred on germination time, plant height, stem diameter, number of leaves, root volume and the extinction ratio. Root (NPA). Testing the immersion concentration of GA3 150 mgL-1 on the Callina variety gave better growth in germination power, germination speed, root length, plant fresh weight, and plant dry weight compared to the PY ASA 01 variety. Independently the variety only had a higher root volume effect on the Callina variety offspring of the PY ASA 01 variety. Meanwhile, the soaking concentration of GA3 affected stem diameter, root volume, and NPA. GA3 immersion concentration of 150 mgL-1 water produced the highest stem diameter, root volume, and NPA. Application of the optimum soaking concentration of GA3 for the Callina variety of 141.87 mgL-1 water resulted in a maximum dry weight of 0.8274 grams, while  the optimum soaking concentration of GA3 for PY ASA 01 of 150.5 mgL-1 water resulted in a maximum dry weight of 0.610 grams.
