Abstract

The pakchoy plant also faces various challenges in its growth environment, including exposure to abiotic stressors. Heavy metals, such as lead (Pb), are environmental contaminants that can have significant negative impacts on plants. Therefore, this research aims to investigate the resilience of pakchoy plants (Brassica rapa L.) to concentrations of abiotic stress from the heavy metal Pb. This is achieved through a series of experiments to understand the effects of exposure to the heavy metal Pb on growth and to analyze the accumulation of heavy metals in pakchoy plants. Pakchoy plants (Brassica rapa L.) can grow under conditions of heavy metal Pb stress; however, as the concentration of Pb increases, the growth of the plants becomes progressively slower. This is evidenced by a reduction in height, leaf number, plant biomass, and the accumulation of heavy metal Pb in the plant tissues. Consequently, these plants are categorized as phytoremediators due to their ability to accumulate heavy metal Pb.

Abstract

The principle of food sovereignty is a democratized system of food, transparent, environment-based, local products and markets as the main pillars in achieving sustainable food security. Food sovereignty makes a very real contribution to overcoming food insecurity in areas where there are frequent extreme climates, crop failures, dependence on imported food, and encouraging the provision of long-term healthy food (sustainable) that is accessible to all communities (equitable) and encourages local food production and consumption (local wisdom). Food sovereignty seeks to improve the quality of life of farmers and rural communities. Strategies to build food sovereignty can be through (a) Utilization of biodiversity as a sustainable source of food through diversification of local food, (b) Improvement of agricultural cultivation and quality of food production through research and innovation produced by BRIN, (c) Consistency in the implementation of protection of productive agricultural lands from land use conversion, (d) Support for monetary, fiscal policies and access to finance for farmers, fishermen, and other food producers, (e) Improving the technology of processing/downstreaming food commodities in a productive, efficient, competitive, and sustainable manner, (f) Development of infrastructure and food production facilities appropriately and integrated, (g) Synergy of food development policies between the central and regional governments, and (h) Implementation of import duties on food imports to protect domestic food commodities and products.

Abstract

Vegetable waste that is widely distributed in the Cilegon Banten coconut market contains pathogenic bacteria including Staphylococcus aureus, Listeria monocytogenes, Salmonella thypi, and Escherichia coli. These pathogenic bacteria have the potential to cause extraordinary events (KLB), especially food poisoning. The appeal for vegetable waste managers at the Cilegon Banten coconut market to inhibit the growth of pathogenic bacteria is to adopt a clean lifestyle by diligently washing hands with antibacterial hand washing soap after disposal of widely exposed vegetable waste along with a mixture of other infectious waste. Hand washing soap with the active ingredient telang flower kombucha in this study correlated positively in inhibiting the growth of four pathogenic bacteria. Research results have proven that hand washing soap at a concentration of 40% is the best antibacterial treatment.

Abstract

Planting sunflowers more densely was intended to maximize the use of nutrients, water and light so that you will get maximum results, but populations that were too dense or too low will not provide maximum results. The research aims to obtain the optimal planting distance and number of plants per hole to obtain high quantity and quality results. The research used a Randomized Completly Block Design (RCBD) factorial experiment consisting of two factors with the first factor being the planting distance in rows with four levels, namely J1 = 25 cm, J2 = 30 cm, J3 = 35 cm, and J4 = 40 cm, while the factor second is the plant population per planting hole (P) which consists of 2 levels, namely P1 = one plant per planting hole and P2 = two plants per planting hole. There were 8 experimental treatments which were repeated 3 times, arranged in a randomized completely block design. The research results concluded that there was no interaction between the plant spacing treatment factor and the number of plants per planting hole treatment factor for all research variables except plant height. The highest plant height value was at a shorter planting distance, namely 25-30 cm with one plant per planting hole. The variables number of leaves, flower diameter and flower weight had the highest values ​​in one plant per planting hole. For farmers who want to grow sunflowers, it was recommended to plant one plant per planting hole, the planting distance can be narrowed to get the ideal plant population.
