Drought on agricultural land disrupts the growth and production of soybean plants, application of salicylic acid is thought to be able to suppress water stress. This research aimed to examine the growth and production of soybean plants due to drought stress and the application of salicylic acid. The research design used was 3 x 3 Factorial Complete Randomized Design, three repetitions, so there were 27 experimental units. The first factor was drought stress 80% field capacity, 60% field capacity, and 40% field capacity. The second factor was concentration of salicylic acid 0 mM (control), 0,5 mM, and 1 mM. Parameters observed were number of leaves, leave area, fresh weight of biomass, dry weight of biomass, fresh weight of root, dry weight of root, fresh weight of pod, and dry weight of pod. The results showed that 40% field capacity reduced all parameters observed, while the application of salicylic acid up to 1 mM was not able to increase the fresh weight of pods under conditions of 40% and 60% field capacity. The use of salicylic acid with a concentration of up to 1 mM in severe drought conditions has not been able to reduce the impact of drought stress and maintain the stability of soybean yields.

FOMO (Fear of Missing Out) is a new concept in the study of individual behavior that can influence their decisions in terms of the economy. FOMO is also a study material that is widely mentioned in the financial media today. FOMO has an influential social component to post-decision regret, especially when individuals realize other choices are better made than uncertainty. This study aims to analyze the implications of FOMO in economic activity, especially for consumer behavior and market dynamics. This research uses the SLR (Systematic Literature Review) method in Scopus articles in 2020-2024 with the presentation of analysis through the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) model. Based on the results of predefined inclusion criteria, there are a total of 10 published articles in the last 5 years that analyze in detail about FOMO. These findings show that FOMO (Fear of Missing Out) has a relationship and influence on economic activity in terms of consumer decisions in purchasing investment, fashion products, cosmetics and luxury goods, as well as the use of technology. In addition, based on the results of SLR literature analysis using Watase Uake shows that there are grand theories related to FOMO variables, namely self-determination theory, social determination theory, and attachment theory. FOMO is a variable of economic psychology that exists in individuals at every age. The findings of this study can be a variable of social capital in further research on wise behavior, economics, and individual psychology.

Tomatoes are a popular commodity in Indonesia, with demand increasing every year. The lack of production compared to the demand for tomato commodities requires steps to increase production, one of which is by providing a booster in the form of a natural growth regulator. This study used a Split Plot Design (2x5) with a basic design of Randomized Group Design. The main plot was Tomato Plant Variety, which consisted of two types, namely Fortuna Variety and Servo F1 Variety. The subplots were natural growth regulators consisting of five types: Water, GA3 100 ppm, Sweet Corn Extract equivalent to 100 ppm GA3, Shallot Extract equivalent to 100 ppm, and Moringa Leaf Extract equivalent to 100 ppm GA3. The results showed that the Fortuna tomato variety gave the best results in the parameters of dry weight of biomass per plant and chlorophyll content, while the application of moringa leaf extract gave the best results in the parameter of leaf area.
