Abstract

One of the obstacles in increasing maize production in Indonesia is the low efficiency of fertilizer use by plants as a result of low levels of organic matter in the soil. Although it only occupies a portion of approximately 2-10%, the role played by organic matter in the soil is very large, both in physical, chemical and biological aspects. One of the practical and efficient alternatives to increase organic matter in the soil is through the management of cover crops (TPT). In this study, individually or after being combined into one, three types of TPT were stocked before the harvest of the predecessor plant (rice). As a comparison, plots without TPT were also provided. Rice litter together with TPT biomass from each TPT treatment was returned to the soil after rice was harvested in a separate plot pattern. In each TPT treatment plot, fertilization treatments were made with a dose of 0 kg/ha NPK, 100 kg/ha NPK, 200 kg/ha NPK and 300 kg/ha NPK. The experimental results showed that TPT biomass had a positive impact on increasing the growth and yield of sweet corn on vertisol soils. Provision of cover crops in the form of a mixture of cowpea, mung bean and krotalaria tended to have a better effect than individual administration. From the results of this experiment, it is also known that the provision of precursor plant biomass combined with TPT biomass can reduce the use of chemical fertilizers by 50-60% of the maximum plant requirement.

Abstract

Vertisols are soils that have a high cation exchange capacity but tend to have a low organic matter content. Meanwhile, nutrients availability in vertisol tends to be low because these elements are bound by clay particles, so the nutrient availability is limited for plantsThe aim of this research is to investigate the influence of rice husk biochar and corn cob biochar application on the changes in chemical properties of Vertisol soil and the vegetative growth of mung bean (Vigna radiata L.). The study was conducted using a Randomized Complete Block Design (RCBD) with an experimental approach. There were 8 treatments repeated 6 times, resulting in a total of 48 experimental units. The rice husk biochar (P) treatments included the control without rice husk biochar (BSP0), rice husk biochar at a rate of 60 g/kg soil (150 tons/ha) + 2.5 kg soil (BSP1), rice husk biochar at a rate of 30 g/kg soil (75 tons/ha) + 2.5 kg soil (BSP2), and rice husk biochar at a rate of 15 g/kg soil (37.5 tons/ha) + 2.5 kg soil (BSP3). The corn cob biochar (J) treatments included the control without corn cob biochar (BTJ0), corn cob biochar at a rate of 60 g/kg soil (150 tons/ha) + 2.5 kg soil (BTJ1), corn cob biochar at a rate of 30 g/kg soil (75 tons/ha) + 2.5 kg soil (BTJ2), and corn cob biochar at a rate of 15 g/kg soil (37.5 tons/ha) + 2.5 kg soil (BTJ3). The research data were analyzed using Analysis of Variance (ANOVA) at a significance level of 5%. Significant differences between treatments were further analyzed using the Duncan's New Multiple Range Test (BNJ) at a significance level of 5%. The soil analysis was carried out at the Soil Physics and Soil Chemistry Laboratories, Faculty of Agriculture, Universitas Mataram. The results of the research showed that biochar application influenced the chemical properties of the soil (pH, Cation Exchange Capacity, Organic-C) and the growth of mung bean plants in Lombok's Vertisol soil. Biochar did not have a significant effect on the height of mung bean plants at 7 and 14 days after planting (DAP), but it had a significant effect at 21, 28, and 35 DAP. However, the application of biochar did not significantly affect the number of leaves and dry weight of mung bean plants.

Abstract

This research aims to determine changes in land cover on Gili Meno, Gili Trawangan, and Gili Air as small islands in West Nusa Tenggara Province. The method used in this research is a qualitative descriptive method in comparing land cover changes on each island and also spatial analysis using Google Earth satellite image data in 2013 and 2022. The research results show seven land cover classifications consisting of built-up land, open land, stretches of beach sand, water bodies, plantations, bushes, and mangroves. Based on the analysis of land cover changes in Gili Trawangan, Gili Meno, and Gili Air, a trend of increasing built-up land area for ten years from 2013 to 2022. The most significant increase in built-up land occurred on Gili Trawangan, namely 48.14 Ha. It was followed by Gili Air and Gili Meno, respectively 24.86 ha and 23.71 ha. The driving factor for changes in land cover on Gili Matra is policies from the central, provincial, and regional governments regarding the promotion and establishment of Gili Matra as a tourism destination in NTB Province. Furthermore, this policy impacts the growth of tourists and the number of residents. It causes an increase in the need for tourism-supporting facilities. Therefore, there is a change in land cover, which gradually reduces the area of undeveloped land on Gili Matra.
