Abstract

This study aims to make hydroponic plant cultivation the right alternative to overcome land limitations without the need for soil media. This study aims to determine the impact of using NPK-based sensors on the development of Caisim plants (Brassica Chinensis Var. Parachinensis) in a hydroponic system. The research design used a Completely Randomized Design (CRD) with two treatments, namely hydroponics with and without the help of IoT-based NPK sensors. Parameters include plant height, number and area of leaves, fresh weight, and dry weight. Data were analyzed using an unpaired T test at a significance level of 5%.  The results show that the use of NPK sensors has a significant effect on most growth indicators, except for dry weight. The application of this sensor has been shown to increase the efficiency of nutrient absorption needed by plants.  Therefore, this technology is worthy of being a modern solution in hydroponic cultivation to optimize production results efficiently.

Abstract

Weeds are plants that humans try to manage because they inhibit the growth of cultivated plants or are harmful to human interests. This study aims to evaluate the effect of teki grass extract (Cyperus rotundus) on the growth of green beans (Vigna radiata) and red spinach (Amaranthus dubius). The research method used a completely randomized design (CRD) with two extract concentration treatments (30% and 50%) applied to both plants. The results showed that treatment with teki extract significantly affected plant growth, with a decrease in height and fresh weight at higher concentrations. The allelopathic effect of the teki extract inhibited the vegetative growth of mung beans and red spinach, indicating that this extract has potential as a bioherbicide agent.
