Abstract

There are determining factors in agricultural cultivation technologies that significantly affect plant development and productivity. Fertilization is one of the determining factors in agriculture. This research examines the composition of urea fertilizer and cow manure on kalian growth and yield. This research was conducted from 5 October 2021 to 30 November 2021 in Tunggulrejo Village, Jumapolo, Karanganyar, at an altitude of 700 meters above sea level with red latosol soil. This research used a single-factor Complete Randomized Block Design (RAKL) which consisted of 6 trials, and each was repeated four times to obtain 24 problems. The observational data were analysed using an F test with an error level of 5%. The treatment was continued with the DMRT (Duncan's Multiple Range Test) at an error level of 5% when there was an effect during the treatment. The variables used were plant height, number of leaves, leaf area, fresh plant weight, fresh crown weight, dry crown weight, fresh root weight, and dry root weight. The results of the research indicated that the composition of urea fertilizer and the application of cow manure had a significant effect on the growth of leaves of kalian plants; the best and highest number of leaves was 8 (F): Urea 0% + 100% cow manure per plot while the other parameters did not affect plants.

Abstract

In general, landslides occur when the upward slope is higher than the retaining force which is caused by high rainfall intensity, land slope, load and impermeable layer, soil solum thickness, and soil type. The restraining force is generally controlled by the resistance of soil shear, the density and strength of plant roots and the strength of rocks. This disaster also often occurs in Indonesia, which has many mountains that stretch across the country. This research aims to determine landslide-prone areas, landslide types, dominant factors that cause landslides and landslide mitigation in anticipation of the impact of non-structural climate change. The research included 3 stages, such as pre-field, field, and post-field which are interrelated and complementary. The research location is around landslide-prone lands along the southwest slope of Mount Lawu in Karanganyar Regency, Central Java. Based on the results of the research analysis, it indicates that the southwest slope of Mount Lawu, especially in Karanganyar, is highly prone to landslides. Therefore, it is not suitable to be used as agricultural and residential land because of its area of about 6,797.06 ha, and is categorized into three crucial parts, such as areas that are still highly prone to landslides of about 5,005.35 ha (73.64%); landslide-prone area of 1,784.23 ha (26.25%); and slightly landslide-prone area of 7.48 ha (0.11%).
