Abstract

The use of natural growth regulators offers a sustainable alternative to synthetic compounds in hydroponic systems. This study evaluates the effect of natural plant growth regulators (PGRs) from coconut water and bamboo shoot extract on the growth of green lettuce (Lactuca sativa L.) in a Deep Flow Technique (DFT) hydroponic system and determines the optimal concentration. The experiment, conducted at BPSIP from October to November 2024, used a Completely Randomized Design (CRD) with nine treatments: a control, coconut water, and bamboo shoot extracts at concentrations of 10, 20, 30, and 40 ml L?¹, with three replications. The results showed that PGR applications did not significantly affect most parameters, including plant height at 21 and 35 days after transplanting (DAT), leaf dimensions, fresh shoot weight, and root weight. However, significant effects were observed on plant height at 28 DAT and leaf number at 28 and 35 DAT. Coconut water at 10 ml L?¹ produced the best response for these parameters. These findings confirm that the effectiveness of natural PGRs in DFT hydroponics is concentration-dependent and that under optimal nutrient conditions, their addition does not consistently enhance lettuce growth.

Implementation of health protocols properly and correctly is needed to prevent transmission of the virus in the school environment. However, many students still do not understand how to wash their hands in 6 steps and use protective equipment properly. Objective: To improve a healthy lifestyle for students at SMP Ar-Rohmah Islamic Boarding School during the pandemic Covid-19. Methods: The dedication is carried out with an educational method in the form of hands-on practice on the 6 steps of hand washing and how to use protective equipment correctly. Results: After receiving education, students can apply the 6-step hand washing method and use protective equipment properly and independently. Conclusion: The education that has been carried out has enabled the female students at SMP Ar-Rohmah Islamic Boarding School to apply 6 steps of hand washing and use PPE properly and independently.
